GAO Report on Adapting to Climate Change
Government Accountability Office, Climate Change: Selected Governments Have Approached Adaptation Through Laws and Long-Term Plans, Report to the Honorable Matthew Cartwright, House of Representatives, GAO-16-454, May 2016.
This report focuses on fiscal exposure to climate-related risks and describes (1) how selected governments have approached enhancing resilience to weather-related disasters through climate change adaptation and (2) steps the U.S. government has taken to enhance resilience through climate change adaptation. GAO reviewed literature and government documents; interviewed U.S. and other government officials and stakeholders; and selected a non-generalizable sample of four countries—Mexico, the Netherlands, the Philippines, the United Kingdom—and the European Union for further examination, based on criteria including stakeholder recommendations.

Increasing Water Security
Shah, Tushaar, Increasing Water Security: The Key to Implementing the Sustainable Development Goals, Global Water Partnership (GWP), Stockholm, Sweden, http://www.gwp.org, Background Paper No. 22, 2016.
The new UN Development Agenda and the Sustainable Development Goals (SDGs) adopted in 2015 embodies universal aspirations for achieving a better, more just, equitable, peaceful, and sustainable future and invites us to accept and embrace comprehensiveness and interconnectedness.
The Agenda fully recognizes that water is embedded in all aspects of development – food security, health, and poverty reduction – it is essential for economic growth, and it sustains the natural ecosystems on which everything else depends. The inclusion of the ‘water goal’ (SDG6) puts responsibility for water management and increasing water security in the hands of the water and water using sectors. The Agenda champions the need for an integrated approach to water resources management and provides a ‘green light’ to countries to implement their IWRM plans.
This GWP Technical Committee Background Paper is a timely response to the SDGs. It reviews the IWRM approach and its evolution over the past 25 years towards increasing water security – its successes and disappointments. It is essentially a simple idea which has gradually gained international acceptance, yet putting it into practice has not proved to be easy. IWRM has not been without its critics. Those who have tried to operationalize it have often applied a ‘one-size-fits-all package’ which does not recognize the unique nature of physical, social, economic, political, and environmental circumstances which determine how a country puts IWRM into practice. So it is not surprising that the outcome was often disappointing.
But there are also successes and based on these experiences this review concludes with some strong proposals for successful implementation. It suggests a framework to guide implementation based on the stage of a country’s economic and social evolution with each stage requiring different inputs and actions that are appropriate to a nation’s needs and capabilities. It also suggests a balance is needed between learning from rich countries and adapting to local conditions. The next step is to provide more detailed guidance for wise implementation of IWRM and in turn SDG6.
Congress on Sustaining Western Water
Congress on Sustaining Western Water, Renewable Resources Journal, Renewable Natural Resources Foundation, Vol. 30-2016, No. 1.
The past four years have seen extreme drought in the western United States with no relief in sight. While precipitation patterns in this region are highly variable, the National Climate Assessment predicts that drought trends will likely intensify over this century and beyond, with longer-term droughts anticipated. Nevertheless, population in the western states has increased rapidly, and the region continues to support significant agricultural production. Strategies for coping with drought have a long history in the region, but it will be a challenge to adapt and apply these strategies to severe projected droughts. This report is a summary of the presentations, findings and recommendations of expert speakers and delegates present at the Renewable Natural Resources Foundation’s 2015 Congress on Sustaining Western Water. Professionals from RNRF member organizations and leaders from government, industry, academia and nonprofit organizations attended the meeting.
EPA Releases Report on Conditions in Nation’s Wetlands
EPA has just released the National Wetland Condition Assessment: A Collaborative Survey of the Nation’s Wetlands. The report finds that less than half of wetland area, 48%, is in good condition based on plant community. Of the stressors the NWCA examined, physical alterations to wetland habitat such as surface compaction, ditches, or plant removal are the most widespread: 27% of wetland area nationally has high stress levels for surface hardening and vegetation removal, and 23% of wetland area has high stress levels for ditching. This is the first national monitoring study of the overall condition of wetlands conducted with a statistically-valid random sample approach.
Municipal Freshwater Scarcity
Government Accountability Office, Municipal Freshwater Scarcity, Report to Congressional Requestors, Technology Assessment, GAO 16-474, April 2016.
Water scarcity occurs when the demand for water in a given area approaches or exceeds available water supplies. A water utility facing scarcity may attempt to address it by reducing its demand on existing water supplies, increasing its water supplies, or both. Many mature technologies are available to address both of these areas. For example, a utility could try to improve the efficiency of its distribution system in order to reduce its demand on existing water supplies. Utilities can choose from wide variety of mature technologies to detect leaks, manage pressure, meter water flow, and assess the condition of pipes. Similarly, a utility may be able to increase supplies through choosing from many mature technologies that are available to treat nontraditional water sources such as seawater, brackish water, treated municipal wastewater, or storm water captured from developed surfaces.
Based on GAO’s nationwide survey of municipal water utilities, the percentage of utilities that treat nontraditional water sources for municipal use varies significantly across the United States. According to GAO’s statistical analysis, much of this regional variation can be explained by differences in underlying utility and watershed characteristics. In particular, very large utilities, utilities serving water-stressed areas, and utilities that manage additional services such as wastewater or storm water services are most likely to treat nontraditional water sources for municipal use. GAO also analyzed survey data regarding the challenges that municipal water utilities face in treating nontraditional water. The results of that analysis suggest that utilities that have experience treating nontraditional water sources find it easier to address financial, regulatory, and other challenges than utilities that have only studied the feasibility of doing so.
SECURE Water Act Report
The SECURE Water Report identifies climate change as a growing risk to Western water management and cites warmer temperatures, changes to precipitation, snowpack and the timing and quality of streamflow runoff across major river basins as threats to water sustainability. Water supply, quality and operations; hydropower; groundwater resources; flood control; recreation; and fish, wildlife and other ecological resources in the Western states remain at risk.
The report, which responds to requirements under the SECURE Water Act of 2009, shows several increased risks to western United States water resources during the 21st century. This is the second report produced for Congress. The first report was produced in 2011.

GAO Report on Drinking Water
Government Accountability Office, Drinking Water: EPA Needs to Collect Information and Consistently Conduct Activities to Protect Underground Sources of Drinking Water, Report to Congressional Requestors, GAO-16-281, Feb. 2016.
The Environmental Protection Agency (EPA) has not collected specific inspection and complete or consistent enforcement information, or consistently conducted oversight activities, to assess whether state and EPA-managed Underground Injection Control (UIC) class II programs are protecting underground sources of drinking water. EPA guidance calls for states and EPA regions to report certain information and for EPA to assess whether programs are effectively protecting underground sources of drinking water, but the agency does not. Specifically:
EPA annually collects summary data from state and EPA-managed programs on the types of inspections they conduct. However, these data are not specific enough to determine the number of different types of inspections that states and EPA regions are to conduct to meet their annual goals. Such goals are specified at the well level (e.g., to inspect 100 percent of wells associated with emergency responses). Under federal internal control standards, managers are to compare actual performance to planned or expected results and analyze significant differences. Without well-specific data on inspections, EPA cannot assess whether state and EPA-managed programs are meeting annual inspection goals.
EPA collects information on unresolved significant violations of state and EPA-managed programs to determine if the agency needs to take action to enforce applicable program requirements. However, GAO's analysis of a nongeneralizable sample of 93 significant violations for fiscal years 2008 through 2013 found that state and EPA-managed programs did not report data on such violations completely or consistently. For example, of 29 such violations that had not been enforced after 90 days as required, programs reported 7 to EPA. According to EPA and state officials, the cause was inconsistent interpretations of EPA's reporting guidance. EPA officials said they are aware that the data reported on such violations are not complete or consistent, but the agency has not clarified in guidance what data programs should report. Until it does so, EPA does not have reasonable assurance that it has the data needed to assess if it must take enforcement action.
EPA has not consistently conducted oversight activities necessary to assess whether state and EPA-managed programs are protecting underground sources of drinking water. For example, GAO found in June 2014 that EPA does not consistently conduct oversight activities, such as annual on-site program evaluations. According to EPA guidance, such evaluations should include a review of permitting and inspection files or activities to assess whether the state is protecting underground water. In California, for example, EPA did not regularly review permitting, and in July 2014, after a state review of permitting, EPA determined that the program was out of compliance with state and EPA requirements. EPA officials said that they have few resources to oversee UIC class II programs, but EPA has not conducted a workforce analysis consistent with GAO's work on strategic human capital management to identify the resources needed for such oversight. Without conducting such an analysis, EPA will not be able identify the human capital or other resources needed to carry out oversight of the UIC class II programs to help ensure that they protect underground sources of drinking water.

White House Report on Sustainable Water Resources
Commitments to Action on Building a Sustainable Water Future, White House, March 22, 2016.
Water challenges are facing communities and regions across the United States, impacting millions of lives and costing billions of dollars in damages. Recent events, including record-breaking drought in the West, severe flooding in the Southeast, and the water-quality crisis in Flint, MI, have elevated a national dialogue on the state of our Nation’s water resources and infrastructure. This dialogue is increasingly important as a growing population and changing climate continue to exacerbate water challenges. On March 22, 2016—World Water Day—the Obama Administration hosted the first-ever White House Water Summit to shine a spotlight on the importance of cross-cutting, creative solutions to solving the water problems of today, as well as to highlight the innovative strategies that will catalyze change across the ways in which we use, conserve, protect, and think about water in the years to come. As part of the Summit, the Administration called on institutions and organizations from all sectors to make new commitments to build a sustainable water future in the United States. In response, institutions and organizations made the commitments in this document, as reported and described by respondents.

Grading the condition of the water infrastructure
Every four years, American Society of Civil Engineers (ASCE) sends the nation a Report Card for America’s Infrastructure, which grades the current state of its national infrastructure on a scale of A through F. In 2013, ASCE’s most recent Report Card gave the nation’s infrastructure an overall grade of D+, a slight rise from the 2009 Report Card. As highlighted in figure 1 below, in the water arena all categories were rated at D or below except for ports which were rated C. ASCE indicates that since 1998, grades in all categories have been near failing primarily due to delayed maintenance and underinvestment.
Grades for America’s Infrastructure

The cost to the nation to remediate identified deficiencies and support modernization of the national infrastructure by 2020 is in excess of $3.6 trillion. Figure 2 identifies ASCE’s estimated funding needs for water infrastructure, the expected funding given past history and the $187 billion funding gap that exists as a result. The ASCE figures are supported by information available from the federal agencies involved and other infrastructure reports.

Managing Western Fish, Wildlife and Plants in an Era of Changing Climate and Increasing Drought
An Approach to Scenario Planning in the Colorado River Basin: The Colorado River Basin Water Supply and Demand Study
Truckee River Basin Study
WASHINGTON - The Bureau of Reclamation has released its study of the Truckee Basin in California and Nevada, projecting that climate change may impact water supplies in the 21st century. Now available online, this study provides water managers with information to better understand the basin’s water supply and demand from now until 2099, and also identifies potential options to help them meet future demands.
"The Truckee Basin is an important source of water for eastern California and western Nevada and includes the iconic Lake Tahoe," Reclamation Commissioner Estevan López said. "Reclamation and its partners now have the necessary information to develop options to ensure a sustainable water supply into the future."
Reclamation developed the study in partnership with the Truckee Meadows Water Authority, Tahoe Regional Planning Agency, Truckee River Flood Management Authority and Placer County Water Agency.
The Truckee Basin headwaters begin around Lake Tahoe. The basin includes the Truckee and Carson rivers and Pyramid Lake and encompasses the cities of Carson City, Reno and Sparks, as well as Reclamation's Newlands Project, all in Nevada.
According to the basin study, the Truckee Basin is heavily dependent on the Sierra Nevada’s snowpack and available supply is dependent on the availability to capture, store and manage water. Precipitation within the basin can vary greatly from the high elevations in the Sierra Nevada to the desert regions around Pyramid Lake. Year-to-year precipitation can also vary greatly, with several years of below- average precipitation being common.
The mean average annual temperature in the basin is anticipated to increase by up to five degrees Fahrenheit by the end of the twenty-first century, while annual precipitation within the basin may decrease slightly. The increase in temperature will change the timing and intensity of runoff, with more precipitation falling as rain instead of snow. Runoff will begin earlier, thus impacting the amount of water that can be stored in Truckee reservoirs because of current flood management requirements.
Also, limited storage within the basin will impact water supplies. For example, because of the earlier runoff, the ability to meet full storage after April will be reduced. Due to warming, basin reservoirs are also projected to have higher rates of evaporation, and will be less resilient during future droughts. Lake Tahoe’s surface is projected to drop below its natural rim more frequently, causing flows into the Truckee River at Tahoe Dam to cease; making Truckee supplies dependent on smaller reservoirs with limited capacity.
The study also found that the frequency and magnitude of flood events may increase within the basin. The likelihood of the basin experiencing more floods like the one in 1997 that heavily impacted downtown Reno and Sparks, as well as floods of lesser intensity, will increase 10 to 20 percent by 2050 and 30 to 50 percent by 2099.
Finally, the basin study identified structural and non-structural options to balance water supply benefits with flood risks, including working with the U.S. Army Corps of Engineers to allow flexibility in managing reservoir flood space, among other options.
The Truckee Basin Study is a part of WaterSMART. The report is available online at www.usbr.gov/watersmart/bsp.
Waters to which the Clean Water Act applies
EPA and the Army Corps’ “Waters of the United States” Rule: Congressional Response and Options, Claudia Copeland, January 20, 2016, Congressional Research Service, 7-5700, www.crs.gov, R43943
On May 27, 2015, the Army Corps of Engineers (the Corps) and the Environmental Protection Agency (EPA) finalized a rule revising regulations that define the scope of waters protected under the Clean Water Act (CWA). Discharges to waters under CWA jurisdiction, such as the addition of pollutants from factories or sewage treatment plants and the dredging and filling of spoil material through mining or excavation, require a CWA permit. The rule was proposed in 2014 in light of Supreme Court rulings in 2001 and 2006 that created uncertainty about the geographic limits of waters that are and are not protected by the CWA. The rule, which becomes effective August 28, 2015, replaces EPA-Corps guidance that has governed permitting decisions since the Court’s rulings.
According to EPA and the Corps, their intent in proposing the rule was to clarify CWA jurisdiction, not expand it. Nevertheless, the rule has been extremely controversial, especially with groups representing property owners, land developers, and agriculture, who contend that it represents a massive federal overreach beyond the agencies’ statutory authority. Most state and local officials are supportive of clarifying the extent of CWA-regulated waters, but some are concerned that the rule could impose costs on states and localities as their own actions become subject to new requirements. Most environmental advocacy groups welcomed the proposal, which would more clearly define U.S. waters that are subject to CWA protections, but beyond that general support, some in these groups favor an even stronger rule. The final rule contains a number of changes to respond to criticisms of the proposal, but the revisions may not satisfy all critics of the rule.

Since 2005, Canada has followed international developments in transboundary groundwater issues in cooperation with its southern neighbor the United States (USA) within the Internationally Shared Aquifer Resources Management Initiative (ISARM) of UNESCO. As a result, 10 Transboundary Aquifer Systems (TAS) were identified along the border between Canada and the USA. This study is an extensive review of the current state of the 10 TAS. Documentation of scientifically-based knowledge on TAS is an important step in identifying potential issues in policies that might be adopted to address shared water-resource issues.

GAO Report on Water in the Energy Sector
Government Accountability Office, Water in the Energy Sector, Reducing Freshwater Use in Hydraulic Fracturing and Thermoelectric Power Plant Cooling, Technology Assessment, Report to Congressional Requestors, GAO-15-545, August 2015.
Many regions within the United States experience moderate to exceptional drought forcing state officials to make difficult choices regarding energy and water. Competition for freshwater continues to increase due to industrial, municipal, and especially agricultural and energy sector demand. The thermoelectric power industry, for example, accounted for 38 percent of all freshwater withdrawals in the United States in 2010.
GAO has issued a series of six reports on the interdependencies between energy and water. In this report, GAO assessed advanced and emerging technologies that can reduce water use in hydraulic fracturing and thermoelectric power plant cooling. GAO also examined the impact of regional differences in thermoelectric power generation on water use in water-stressed versus unstressed areas of the United States.
Waterless and water-efficient fracturing technologies such as gas-based fracturing or foams have been used to reduce the use of freshwater in hydraulic fracturing operations, although the main benefit is enhanced hydrocarbon recovery. The geologic formation characteristics of shale plays largely determine their use. According to experts GAO consulted, hydraulic fracturing operators are managing their water resources more efficiently—for example, by treating produced water for recycle and reuse—as an important part of their overall strategy to reduce cost, improve operational efficiency, and reduce the demand for freshwater.
GAO Report on Floods and Crops
Government Accountability Office, Climate Change, Better Management of Exposure to Potential Future Losses is Needed for Federal Flood and Crop Insurance, Report to Congressional Requestors, GAO-15-28, Oct. 2014.
The May 2014 National Climate Assessment indicates that the frequency and/or severity of many weather and climate extremes may increase with climate change. Public and private property insurers can bear a large portion of the financial impact of such weather-related losses. In the public sector, federal insurance includes the National Flood Insurance Program (NFIP), managed by the Federal Emergency Management Agency (FEMA), and the federal crop insurance program, managed by the Risk Management Agency (RMA).
Since GAO’s 2007 report on flood and crop insurance, exposure growth in hazard-prone areas has increased losses, and climate change and related increases in extreme weather events may further increase such losses in coming decades. Scientific and industry studies GAO reviewed generally found that increasing growth and property values in hazard-prone areas have increased losses to date and that climate change may compound this effect. From 2007 through 2013, data from the Federal Emergency Management Agency (FEMA) and the Risk Management Agency (RMA) show that exposure to potential losses for insured property grew from $1.3 trillion to $1.4 trillion (8 percent). According to industry data, private sector exposure to such loss grew from $60.7 trillion to $66.5 trillion (10 percent) from 2007 through 2012. Federal exposure to uninsured loss also increased by 46 percent over this period, based on a 2013 analysis by the Congressional Research Service. According to the studies GAO reviewed, climate change may substantially increase losses by 2040 and increase losses from about 50 to 100 percent by 2100.
GAO recommends that FEMA and RMA take additional steps to encourage flood and crop insurance policyholders to adopt building and agricultural practices that reduce long-term risk and federal exposure to losses. FEMA agreed with GAO’s recommendation, and RMA neither agreed nor disagreed with GAO’s recommendation.
GAO Report on Great Lakes
Government Accountability Office, Great Lakes Restoration Initiative, Improved Data Collection and Reporting Would Enhance Oversight, Report to the Chairman, Subcommittee on Water Resources and Environment, Committee on Transportation and Infrastructure, House of Representatives, GAO-15-526, June 2015.
The Great Lakes Restoration Initiative (GLRI) seeks to address issues such as water quality contamination and nonnative, or “invasive,” species that threaten the health of the Great Lakes ecosystem. A Task Force of 11 federal agencies, chaired by the EPA Administrator, oversees the GLRI. Task Force agencies conduct work themselves or through agreements with nongovernmental organizations, academic institutions, or other entities.
Among other things, GAO recommended in its draft report that EPA determine if it should continue using the Great Lakes Accountability System (GLAS) or acquire a different system and ensure that the agency develops guidance for entering data and establishes data quality control activities. EPA took action to address these recommendations as GAO completed its work. GAO reviewed the actions taken and determined that the recommendations had been addressed. As a result, GAO removed the recommendations.
Hydrology and Water Security
Gordon Young, Siegfried Demuth, Anil Mishra, and Christophe Cudennec, Hydrological Sciences and Water Security: An Overview, Proceedings of the 11th Kovacs Colloquium, Paris, France, June 2014.
This paper provides an introduction to the concepts of water security including not only the risks to human wellbeing posed by floods and droughts, but also the threats of inadequate supply of water in both quantity and quality for food production, human health, energy and industrial production, and for the natural ecosystems on which life depends. The overall setting is one of constant change in all aspects of Earth systems. Hydrological systems (processes and regimes) are changing, resulting from varying and changing precipitation and energy inputs, changes in surface covers, mining of groundwater resources, and storage and diversions by dams and infrastructures. Changes in social, political and economic conditions include population and demographic shifts, political realignments, changes in financial systems and in trade patterns.
There is an urgent need to address hydrological and social changes simultaneously and in combination rather than as separate entities, and thus the need to develop the approach of ‘socio-hydrology’. All aspects of water security, including the responses of both UNESCO and the International Association of Hydrological Sciences (IAHS) to the concepts of socio-hydrology, are examined in detailed papers within the volume titled Hydrological Sciences and Water Security: Past, Present and Future.

Costs of Inaction at the Salton Sea
Cohen, Michael J., Hazard’s Toll, the Costs of Inaction at the Salton Sea, Pacific Institute, CA, Sept. 2014.
The Salton Sea, a 350 square mile saltwater lake in southeastern California, faces disaster. In the next fifteen years:
The amount of water flowing into the lake will decrease by about 40%;
Its surface will drop by twenty feet and its volume will decrease by more than 60%;
Salinity will triple; and
The shrinking lake will expose 100 square miles of dust–generating lake bottom to the region’s blowing winds, worsening the already poor air quality in the region.
The deteriorating conditions at the Salton Sea will have adverse impacts on public health, property values, agricultural production, recreational revenue, and the region’s habitat value for birds and wildlife generally. These impacts impose costs on people in the area.
The high costs of the California Natural Resources Agency’s proposed ‘preferred alternative’ have inhibited deliberation and deterred any meaningful investment in the revitalization of the Salton Sea. The assumption seems to be that delaying action at the Salton Sea will result in business as usual, with no additional costs. This is clearly not the case. Because the Salton Sea has changed over the past decade and will soon enter a period of very rapid deterioration, the costs of inaction are escalating rapidly. When a project is implemented dramatically affects the inaction costs estimated above. Postponing decisions and actions for the Salton Sea imposes significant costs on the people and property owners in the region, and lesser costs on Californians generally.
EPA Report on Stream Connectivity
U.S. EPA. Connectivity of Streams and Wetlands to Downstream Waters: A Review and Synthesis of the Scientific Evidence (Final Report). U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-14/475F, 2015.
The objective of the Clean Water Act is to restore and maintain the chemical, physical, and biological integrity of the nation’s waters. The U.S. Environmental Protection Agency’s (U.S. EPA’s) Office of Research and Development developed this report to inform rulemaking by the U.S. EPA and U.S. Army Corps of Engineers (U.S. ACE) on the definition of “waters of the United States” under the Clean Water Act (CWA). Its purpose is to summarize current scientific understanding about the connectivity and mechanisms by which streams and wetlands, singly or in aggregate, affect the physical, chemical, and biological integrity of downstream waters. The focus of the review is on surface and shallow subsurface connections of small or temporary streams, nontidal wetlands, and certain open waters. Because this report is a technical review of peer-reviewed scientific literature, it neither considers nor sets forth legal standards for CWA jurisdiction, nor does it establish EPA policy.
EPA identified five categories of functions by which streams, wetlands, and open waters influence the timing, quantity, and quality of resources available to downstream waters:
• Source: the net export of materials, such as water and food resources;
• Sink: the net removal or storage of materials, such as sediment and contaminants;
• Refuge: the protection of materials, especially organisms;
• Transformation: the transformation of materials, especially nutrients and chemical contaminants, into different physical or chemical forms; and
• Lag: the delayed or regulated release of materials, such as storm water.
These functions are not mutually exclusive; for example, the same stream
or wetland can be both a source of organic matter and a sink for nitrogen.
USGS Report on Water-Energy Nexus
Healy, R.W., Alley, W.M., Engle, M.A., McMahon, P.B., and Bales, J.D., 2015, The water-energy nexus—An earth science perspective: U.S. Geological Survey Circular 1407, 107 p., http://dx.doi.org/10.3133/cir1407.
Water availability and use are closely connected with energy development and use. Water cannot be delivered to homes, businesses, and industries without energy, and most forms of energy development require large amounts of water. The United States faces two significant and sometimes competing challenges: to provide sustainable supplies of freshwater for humans and ecosystems and to ensure adequate sources of energy for future generations. This report reviews the complex ways in which water and energy are interconnected and describes the earth science data collection and research that can help the Nation address these important challenges.
The earth sciences have been a cornerstone in developing our current understanding of the water-energy nexus. A full understanding of the nexus, however, is limited by uncertainty in our knowledge of fundamental issues, such as the quantity of freshwater that is available, the amount of water that is used in energy development, the effects that emerging energy development technologies have on water quality and quantity, and the amount of energy required to treat and deliver freshwater. Enhanced data collection and research can improve our understanding of these important issues and thereby lay the groundwork for informed resource management.
Relevant earth science issues analyzed and discussed herein include freshwater availability; water use; ecosystems health; assessment of saline water resources; assessment of fossil-fuel, uranium, and geothermal resources; subsurface injection of wastewater and carbon dioxide and related induced seismicity; climate change and its effect on water availability and energy production; byproducts and waste streams of energy development; emerging energy-development technologies; and energy for water treatment and delivery.
Water Use Trends in the United States
Donnelly, Kristina and Heather Cooley, Water Use Trends in the United States, Pacific Institute, Oakland, CA, April 2015.
Total water use in the United States declined markedly in the five-year period ending in 2010, according to data released from the United States Geological Survey (USGS). Total water use in the U.S. is now lower than it was in 1970, despite continued population and economic growth. The Pacific Institute analyzes and explains the factors contributing to this positive news, while including a cautionary note, in a new report released on April 15.
The Pacific Institute, an internationally-renowned independent think tank focused on water issues reviewed the USGS’ most recent data collection, along with historical, national water use data. Remarkably, water use in 2010 was down in all sectors – agriculture, municipal and industrial, and thermoelectric power. The Pacific Institute’s new report shows that reductions in water use for thermoelectric power generation – the single largest use of water in the U.S. – accounted for nearly two-thirds of the reduction in water use between 2005 and 2010. This represents an important reversal of a 25-year trend of increasing water use to produce energy. In addition, water use for agricultural irrigation was at its lowest level in more than 40 years, even while the number of acres irrigated increased.
The report shows that, from 2005 – 2010, per capita water use in the United States declined 17% to 1,200 gallons per person per day, levels not seen since the 1940s and the single largest decline in any five-year period. Moreover, the economic productivity of water – which measures the dollars of Gross Domestic Product per unit of water used – increased by 20% during that period to an all-time high of $11.49 per 100 gallons, an indication that the U.S. produces far more wealth, with less water than at any time in the past.
While these trends reveal overall improvements in the management of our nation’s water, the current pace of its use is still not sustainable. Continued population and economic growth, along with the impacts of climate change, will strain the amount of water available for a thirsty nation.
“The data suggest that national water use is moving in the right direction, but this doesn’t mean the work is done or that existing efforts are sufficient,” states lead author Kristina Donnelly. “We must continue to improve water use efficiency in our homes, businesses, and on America’s farms in order to ensure a sustainable water supply for the nation.”
Water Use in the Denver Basin
Binney, Peter D., "Conjunctive Use in the Denver Basin: The Three Way Agreement" (2000).Water and Growth in the West (Summer Conference, June 7-9).
The rapidly developing communities in the south Denver area include a series of incorporated towns, special purpose (metropolitan and water) districts and unincorporated areas of Arapahoe and Douglas Counties. Recent projections indicate that this area will see a four-fold increase in their water demands at the ultimate build-out level.
These communities lie outside the Combined Service Area of the Denver Water Board and have been developing their own water supplies to meet their municipal demands. Approximately two thirds of their water supplies are developed from the non-tributary groundwater supplies in the Denver Basin that underlie these communities. Because of the physical nature of this aquifer, it is considered a non-renewable water resource and so the primary water supply is depleting as water is withdrawn for consumptive uses. County commissioners and utility managers have recognized that eventually new and sustainable water resources will have to be developed for this area and have initiated a process to identity when and how those water sources could be developed.
The Douglas County Commissioners have supported the development of the South Metro Water Supply Study Board (“Study Board”) as the responsible special-purpose district to investigate the alternatives available for developing these new water sources. The Study Board has responded to a series of resolutions that have resulted in a three-way agreement with the Denver Water Board and the Colorado River Water Conservation District. The planning process also responds to the Denver Water Board’s 1995 Resource Statement that outlines the terms under which this well established water utility will consider co-operative efforts or water supply contracts with new areas of demand outside the Combined Service Area..
The participants in that Agreement have all recognized that the key to successfully addressing the many issues involved will require a level of co-operation and collaboration that has been atypical of water development in the West. Limited and drought-prone water resources coupled with increasingly complex regulatory and decision-making settings have severely restricted the ability of municipalities to structurally develop water resources to meet future consumptive demands. Co-operative planning, development and operation of regional water resources between the basin-of-origin, existing water utilities and the new growth areas as well as regulators and the public interest are seen as a viable way in which water supply infrastructure needs will be met in the future.
Adapting to Climate Change in California
Davis, Frank W. and Elizabeth Chornesky, Adapting to Climate Change in California, Bulletin of the Atomic Scientists, 2014 70:62, University of California, Santa Barbara.
Many aspects of the Californian approach to controlling the greenhouse gases that cause climate change now have a sufficient track record to provide potential models or lessons for national and even international action. In comparison, the state’s efforts on climate change adaptation, although multifaceted, are less well developed and thus far have focused largely on information sharing, impact assessments, and planning. Still, adaptation could advance more quickly in California than in many other regions, given relatively high public awareness and concern, extensive scientific information, a strong tradition of local and regional planning, and some enabling policies and institutions. Much more political support and sufficient financing will have to be mustered at state and local levels to enable new projects and initiatives to cope with sea level rise, water management, and ecosystem adaptation, not to mention public health and other key areas of concern. Even so, California’s initial efforts to adapt to unavoidable changes in climate may offer insights for other governments that will, inevitably, need to fashion their own adaptation strategies.
EPA Report on Fracking
The EPA released its peer-reviewed analysis of over two years of data from the FracFocus Chemical Disclosure Registry 1.0. FracFocus is a publicly accessible website, managed by the Ground Water Protection Council (GWPC) and Interstate Oil and Gas Compact Commission, where oil and gas production well operators can disclose information about ingredients used in hydraulic fracturing fluids at individual wells.
Along with the report, the EPA is making available the:
The FracFocus 1.0 data analysis will be combined with a broad review of existing literature, other EPA research, and input we’ve collected through our outreach efforts in the Draft Assessment of Potential Impacts of Hydraulic Fracturing on Drinking Water Resources. When final, the Assessment will provide a new lens to help our states and communities better understand the potential impacts on our drinking water resources from hydraulic fracturing.
About 115 million people—more than one-third of the Nation’s population—rely on groundwater for drinking water. As the Nation’s population grows, the need for high-quality drinking-water supplies becomes even more urgent.
Over the last two decades, USGS scientists have assessed water quality in source (untreated) water from 6,600 wells in extensive regional aquifers that supply most of the groundwater pumped for the Nation’s drinking water, irrigation, and other uses. This comprehensive sampling, along with detailed information on geology, hydrology, geochemistry, and chemical and water use, can be used to explain how and why aquifer vulnerability to contamination varies across the Nation.
The recently completed national summary report of the quality of the Nation’s groundwater is now available online.

B. I. Cook, T. R. Ault, J. E. Smerdon, Unprecedented 21st century drought risk in the American Southwest and Central Plains. Sci. Adv. 1, e1400082 (2015).
In the Southwest and Central Plains of Western North America, climate change is expected to increase drought severity in the coming decades. These regions nevertheless experienced extended Medieval-era droughts that were more persistent than any historical event, providing crucial targets in the paleoclimate record for benchmarking the severity of future drought risks.
We use an empirical drought reconstruction and three soil moisture metrics from 17 state-of-the-art general circulation models to show that these models project significantly drier conditions in the latter half of the 21st century compared to the 20th century and earlier paleoclimatic intervals.
This desiccation is consistent across most of the models and moisture balance variables, indicating a coherent and robust drying response to warming despite the diversity of models and metrics analyzed. Notably, future drought risk will likely exceed even the driest centuries of the Medieval Climate Anomaly (1100–1300 CE) in both moderate (RCP 4.5) and high (RCP 8.5) future emissions scenarios, leading to unprecedented drought conditions during the last millennium.
Cody, Betsy A., et al, Water Resource Issues in the 114th Congress, Congressional Research Service, 7-5700, R42947, Jan. 23, 2015.
The 114th Congress faces many water resource development, management, and protection issues. Congressional actions shape reinvestment in aging federal infrastructure (e.g., dams, locks, and levees) and federal and nonfederal investment in new infrastructure, such as water supply augmentation, hydropower projects, navigation improvements, and efforts to restore aquatic ecosystems. These issues often arise at the regional or local levels, but often have a federal connection.
Ongoing issues include competition over water, drought and flood responses and policies, competitiveness and efficiency of U.S. harbors and waterways, and innovative and alternative financing approaches. The 114th Congress also may continue oversight of operations of federal infrastructure during drought and low-flow conditions, past large-scale flooding issues (e.g., Hurricane Sandy, Hurricane Katrina, Missouri and Mississippi River floods), and balancing hydropower generation, recreational use, and protection of threatened and endangered species.
In addition to oversight, each Congress also provides appropriations for major federal water resource agencies, such as the U.S. Army Corps of Engineers (Corps) and the Bureau of Reclamation (Reclamation).
Because of recent water conditions, disasters, or legal or agency developments, certain river basin issues are particularly likely to receive congressional attention during the 114th Congress. The Columbia River, Missouri River, and Sacramento and San Joaquin River (Central Valley Project) basins fall into this category. Other potential topics of congressional interest include emergency drought or flood legislation, private and public hydropower, water research and science investment and coordination, aging infrastructure, and environmental policy.
Poddar, Sandeep, Water – Threat of the Century, Green University Review of Social Sciences, Vol. 01, Issue 01, June 2014.
Population growth, climate change, and mismanagement of water resources and unnecessary waste of water threatens the sources of potable water. Agriculture and energy resources also face problem due to water scarcity. Global warming can cause a severe condition by 2100. In spite of using ground water in the agricultural sector, waste water can be used, keeping in mind the proper disinfection and pollution criteria. With increase of population, the global food production requirement is going to be double over the next 40 years to meet the needs. And we cannot increase the usage of river and ground water.
Russo, Tess, Katherine Alfredo, and Joshua Fisher, Sustainable Water Management in Urban, Agricultural, and Natural Systems, Water, 2014, 6, 3934-3956.
Sustainable water management (SWM) requires allocating between competing water sector demands, and balancing the financial and social resources required to support necessary water systems. The objective of this review is to assess SWM in three sectors: urban, agricultural, and natural systems. This review explores the following questions: (1) How is SWM defined and evaluated? (2) What are the challenges associated with sustainable development in each sector? (3) What are the areas of greatest potential improvement in urban and agricultural water management systems? And (4) What role does country development status have in SWM practices?
The methods for evaluating water management practices range from relatively simple indicator methods to integration of multiple models, depending on the complexity of the problem and resources of the investigators. The two key findings and recommendations for meeting SWM objectives are: (1) all forms of water must be considered usable, and reusable, water resources; and (2) increasing agricultural crop water production represents the largest opportunity for reducing total water consumption, and will be required to meet global food security needs. The level of regional development should not dictate sustainability objectives, however local infrastructure conditions and financial capabilities should inform the details of water system design and evaluation.
International Groundwater Resources Assessment Centre (IGRAC)
IGRAC has published the new Transboundary Aquifers of the World Map (TBA Map). The TBA Map 2014 shows 608 identified transboundary aquifers, including 226 transboundary ‘groundwater bodies' as defined in the European Union Water Framework Directive (EU WFD), underlying almost every nation.
The TBA Map 2014 shows the state of information presently available on the occurrence and extent of transboundary aquifers world-wide. The map provides a global overview of these important shared water resources and intends to encourage further research and assessment thereof. The map is based on the most recent inventory results of many active working groups around the world. Inventories and assessment of TBAs across the world, followed by information exchange among states sharing an aquifer are considered prerequisites for appropriate TBA governance. This map aims to contribute to raising awareness on the importance of the governance of shared aquifer resources and to building the much needed global knowledge base. Full detail on the methodology creating this map as well as definitions and additional information such as on the legend are given on the back side of the map.
There are now 608 identified transboundary aquifers, including 226 transboundary ‘groundwater bodies' as defined in the European Union Water Framework Directive (EU WFD), underlying almost every nation. At present there are 83 TBAs in Africa, 73TBAs in Americas, 138 TBAs in Asia and 1 TBA in Oceania. In Europe 87 TBAs have been identified and 226 transboundary groundwater bodies (GWB). The number of TBAs and GWB has been increasing steadily since the first ‘Transboundary Aquifers of the World Map' was released in 2009 (380) and in 2012 (455). It is likely that new TBAs will still be identified in the future and that the delineation of existing TBAs may be refined once further studies are conducted.

Chesapeake Bay Program
The Chesapeake Bay is the nation’s largest estuary and its watershed is home to nearly 18 million people. In 1983, the Chesapeake Bay Agreement established the Chesapeake Bay Program, a landscape-level partnership charged with bay restoration. Al Todd served as the Bay Program’s U.S. Forest Service liaison from 1992-98 and now is executive director of the nonprofit Alliance for the Chesapeake Bay. Todd spoke with the Sustainable Forests Roundtable about the Bay Program, which relies heavily on forests to reach its restoration goals.
More information about the Chesapeake Bay Program can be found on the web at http://sustainableforests.net/chesapeake-bay-program-2000-partners-watershed-18-million-people/
“All future developments have to be offset; there can be no new sources of pollution, essentially. Some see that as a real opportunity in the realm of forests. Forests are a permanent offset to many of these issues, whether that means future reinvestments in restoration, urban forestry or protection of existing forests. Water conservation was high on our list, so we did fairly extensive forest mapping on the watershed to see where the highest value of forest is for watershed protection and watershed resilience. We were able to use data from a variety of GIS databases – soils, water supply protection, patch dynamics, fisheries info.
Sea level rise is going to have a huge financial impact. On the mitigation side, obviously that’s where we’re trying to talk trees. In the long run, globally, that’s part of our solution. Environmental markets, working on cap and trade. We do tree planting for carbon offsets.
The two biggest water quality threats are manure from agriculture and stormwater runoff. One of our biggest struggles is around social issues, receptivity – what types of incentives will work. There are a lot of tools, but we still struggle with trying to get private landowners to participate. But we can kind of be the broker for federal programs. The farmers really do like to work with a nonprofit or conservation group versus the government. Many of them just wouldn’t prefer letting the government on their farm.”
Assessment of Mercury Contamination in Streams
A new USGS report presents a comprehensive assessment of mercury contamination in streams across the United States. It highlights the importance of environmental processes, monitoring, and control strategies for understanding and reducing stream mercury levels.
Methylmercury concentrations in fish exceed the human health criterion in about one in four U.S. streams.
Mercury contamination of fish is the primary cause of fish consumption advisories, which currently exist in every state in the nation. Mercury can travel long distances in the atmosphere and be deposited in watersheds, thus contaminating fish even in areas with no obvious source of mercury pollution.
“Understanding the source of mercury, and how mercury is transported and transformed within stream ecosystems, can help water resource managers identify which watersheds are most vulnerable to mercury contamination. They can then prioritize monitoring and management actions,” said William Werkheiser, USGS Associate Director for Water.
Some of the highest fish mercury levels were found in southeastern U.S. streams draining forested watersheds containing abundant wetlands.
Wetlands provide ideal conditions for atmospherically deposited mercury to be converted to methlymercury — which enters the aquatic food web and ultimately bioaccumulates in fish, especially top predator game fish such as largemouth bass. Thus, wetland construction or restoration (for example, to improve habitat or to filter nutrients and sediment) should balance the potential for increased methylmercury production against the anticipated ecological and water-quality benefits of the wetlands.
Elevated mercury levels also were noted in areas of the western U.S. affected by historical gold and mercury mining.
Fish mercury levels were lowest in urban streams, despite an abundance of sources of inorganic mercury. This occurs because urban streams lack conditions, such as wetlands, that are conducive to production and bioaccumulation of methylmercury.
In contrast to other environmental contaminants, mercury emission reduction strategies need to consider global mercury sources in addition to domestic sources. Reductions in domestic mercury emissions are likely to result in lower mercury levels in fish in the eastern U.S., where domestic emissions contribute a large portion of atmospherically deposited mercury. In contrast, emission controls will provide smaller benefits in the western U.S., where reduced domestic emissions may be offset by increased emissions from Asia.
Atmospheric mercury emissions from municipal and medical waste incineration, metallurgical processes, and other sources have been reduced in the U.S. by more than 60 percent since 1990. Mercury concentrations in lake sediment, fish tissue, and precipitation have decreased in some areas of the U.S. during recent decades, coincident with mercury reduction legislation. The development of a national monitoring approach will be critical to track the effectiveness of future management actions.
GAO Report on USDA Climate Change Efforts
Climate Change: USDA’s Ongoing Efforts Can Be Enhanced with Better Metrics and More Relevant Information for Farmers, Report to the Ranking Member, Committee on Energy and Commerce, House of Representatives, U.S. Government Accountability Office, GAO-14-755, Sept. 2014.
The U.S. Department of Agriculture’s (USDA) climate change priorities for agriculture include, among other things, providing better information to farmers on future climate conditions. These priorities generally align with national priorities set by the Administration, which include promoting actions that reduce greenhouse gas emissions, advancing climate science, developing tools for decision makers, and developing better projections of future climate conditions. USDA is engaged in research efforts aimed at better understanding climate change’s impacts on agriculture and providing technical assistance to farmers. Through the use of existing conservation and energy programs, USDA aims to reduce greenhouse gas emissions and sequester (store) carbon so it is not released, or is actively withdrawn, from the atmosphere.
GAO recommends that USDA develop performance measures that better reflect the breadth of USDA climate change efforts and use its performance plans and reports to provide information on how the agency plans to achieve its goals and the status of its efforts. GAO also recommends that USDA develop and provide information to farmers on the economic costs and returns of taking certain actions in response to climate change. USDA concurred with these recommendations.
New USGS Study Summarizes 20 year Occurrence and Trends of Pesticides in U.S. Streams and Rivers
Levels of pesticides continue to be a concern for aquatic life in many of the Nation’s rivers and streams in agricultural and urban areas, according to a new USGS study spanning two decades (1992-2011). In contrast, pesticide levels seldom exceeded human health benchmarks.
Over half a billion pounds of pesticides are used annually in the U.S. to increase crop production and reduce insect-borne disease, but some of these pesticides are occurring at concentrations that pose a concern for aquatic life.
The proportion of streams with one or more pesticides that exceeded an aquatic-life benchmark was similar between the two decades for streams and rivers draining agricultural and mixed-land use areas, but much greater during the 2002-2011 for streams draining urban areas. Fipronil, an insecticide that disrupts the central nervous system of insects, was the pesticide most frequently found at levels of potential concern for aquatic organisms in urban streams during 2002-2011. Fipronil registration and subsequent use in the U.S. began during the late 1990’s and it was used as an alternative to organophosphate insecticides for residential and commercial applications during the early-2000’s.
1992, there have been widespread trends in concentrations of individual
pesticides, some down and some up, mainly driven by shifts in pesticide use due
to regulatory changes, market forces, and introduction of new pesticides.

Government Accountability Office, Missouri River Flood and Drought, Experts Agree the Corps Took Appropriate Action, Given the Circumstances, but Should Examine New Forecasting Techniques, GAO-14-741, Sept. 2014.
The Missouri River stretches from western Montana to St. Louis, Missouri. The Corps manages six dams and reservoirs on the river to provide flood control and for other purposes, such as recreation and navigation. The Corps bases reservoir release decisions on the guidance in the Master Manual. In the 2011 flood, the Corps managed the highest runoff volume since 1898, resulting in record reservoir releases. Subsequently, drought occurred in the basin in 2012 and 2013.
GAO was asked to review the Corps’ release decisions and communication during the flood and drought. This report examines (1) experts’ views on the Corps’ release decisions; (2) experts’ recommendations to improve the Corps’ release decisions; and (3) stakeholders' views on the Corps’ communication, as well as any suggested improvements. GAO worked with the National Academy of Sciences to convene a meeting of nine experts to discuss the Corps’ data, forecasts, and release decisions. GAO also interviewed 45 Missouri River basin stakeholders, including state and local agencies, among others, to discuss their views on the Corps’ communication. The views of stakeholders are not generalizable.
What GAO Recommends
GAO recommends that the Corps evaluate the pros and cons of incorporating new forecasting techniques into its management of the Missouri River reservoirs. The Department of Defense concurred with the recommendation.
Amarasinghe, U. A.; Smakhtin, V. 2014. Global water demand projections: past, present and future. Colombo, Sri Lanka: International Water Management Institute (IWMI). 32p. (IWMI Research Report 156). doi: 10.5337/2014.212
Water demand projections (WDPs) are widely used for future water resource planning. Accurate WDPs can reduce waste or scarcity associated with overdevelopment or underdevelopment, respectively, of water resources. Considering that the projection period of some WDPs have now passed, this paper examines how closely such past projected withdrawals match current water withdrawals to identify lessons that can be learned and strengthen future studies on WDPs. Six WDPs conducted before 1990 and seven conducted after 1990 are analyzed in detail. The review shows that the pre-1990 WDPs, which considered population as the main driver of change, overpredicted current water use by 20 to 130%. Unrealistic assumptions on the norms of water use in different sectors were the main reasons for large discrepancies.
The post-1990 WDPs had sophisticated modeling frameworks. They integrated many exogenous and endogenous drivers of food and water supply and demand, with refined estimation procedures for domestic and industrial sectors. Yet, the post-1990 WDPs of the ‘business as usual’ (BAU) scenarios show substantial underestimation globally, and large deviations for sectors and countries, from the current water-use patterns; the sustainable water use scenarios are even more downward biased. The average per capita domestic water withdrawals at present already exceed projections made by the BAU scenario for 2025. Still, many low-income countries have fairly low levels of withdrawals. The demand projections for the industrial sector are no better; the relatively large differences are in the low-income countries. BAU projections for the agriculture sector are mostly under- or over-estimated (-11% to 3%). For India, the underestimation ranges from 20 to 90 billion cubic meters (Bm3) or 3 to 14% of the total water withdrawals. For China, they over-estimated the demand by 37-54 Bm3 or 7 to 11% of the total withdrawals. The projections for many small countries also differ substantially compared to their current water withdrawals. Moreover, there is no analysis that assesses the accuracy of projections.
Overall, the value of long-term country-level projections in global WDPs is inadequate for local water resource planning. The accuracy and value of global WDPs could be increased, if past trends, spatial variation across and within countries, and influence of rapidly changing key exogenous and endogenous drivers of water demand in different sectors are taken into account. For individual countries, short-term projections and sensitivity analysis can be more useful.
Great Lakes Restoration Initiative Provides Funding to Target Harmful Algal Blooms in Lake Erie, Sept. 3, 2014
WASHINGTON -- U.S. Environmental Protection Agency Administrator Gina McCarthy today announced that the Great Lakes Restoration Initiative (GLRI) will provide almost $12 million to federal and state agencies to protect public health by targeting harmful algal blooms (HABs) in western Lake Erie. The funding builds upon the GLRI’s on-going efforts to reduce algal blooms and will be made available to Ohio, Michigan and Indiana state agencies and to the U.S. Geological Survey, the USDA Natural Resources Conservation Service and the National Oceanic and Atmospheric Administration.
“The importance of clean water cannot be overstated, which is why the Great Lakes Restoration Initiative is taking further action to target harmful algal blooms in western Lake Erie,” said EPA Administrator Gina McCarthy. “This important funding will address the immediate need for state and federal agencies to protect public health and build upon on-going efforts to reduce harmful algal blooms.”
The new FY 2014 funding will be used to:
· Expand monitoring and forecasting to help drinking water treatment plant operators and beach managers minimize health impacts associated with HABs;
· Increase incentives for farmers in western Lake Erie watersheds to reduce phosphorus runoff that contributes to HABs; and
· Improve measurement of phosphorus loads in Lake Erie tributaries.
In early August, the City of Toledo issued a "Do Not Drink" order for almost 500,000 people in northwest Ohio and southeast Michigan when a drinking water treatment plant was adversely impacted by microcystin, a toxin produced in connection with HAB outbreaks on Lake Erie. In addition to generating toxins that pose risks to human health, HABs create low oxygen "dead zones" and harm shoreline economies.
On August 13, EPA Regional Administrator, Susan Hedman, convened a meeting of federal and state agencies to identify opportunities for collaboration to minimize HAB-related risks in the western Lake Erie Basin. GLRI funding announced today targets immediate needs identified during that meeting. The group will continue to focus resources on this issue in FY 2015 and beyond.
McCarthy, who chairs the Great Lakes Interagency Task Force, which oversees
the Great Lakes Restoration Initiative, made the announcement today at the task
force meeting in Washington, D.C.

Government Accountability Office, Drinking Water, EPA Program to Protect Underground Sources from Injection of Fluids Associated With Oil and Gas Production Needs Improvement, Report to Congressional Requestors, GAO-14-555, June 2014.
Every day in the United States, at least 2 billion gallons of fluids are injected into over 172,000 wells to enhance oil and gas production, or to dispose of fluids brought to the surface during the extraction of oil and gas resources. These wells are subject to regulation to protect drinking water sources under EPA’s UIC class II program and approved state class II programs. Because much of the population relies on underground sources for drinking water, these wells have raised concerns about the safety of the nation’s drinking water.
The Environmental Protection Agency’s (EPA) role in the Underground Injection Control (UIC) class II program is to oversee and enforce fluid injection into wells associated with oil and gas production, known as class II wells. EPA has approved 39 states to manage their own class II programs, and EPA regions are responsible for managing the programs in remaining states. EPA regions and states use a mix of resources to manage class II programs, including EPA grant funding, state funding, and federal and state personnel. EPA’s UIC grant funding has remained at about $11 million for at least the past 10 years.
EPA is not consistently conducting two key oversight and enforcement activities for class II programs. First, EPA does not consistently conduct annual on-site state program evaluations as directed in guidance because, according to some EPA officials, the agency does not have the resources to do so. The agency has not, however, evaluated its guidance, which dates from the 1980s, to determine which activities are essential for effective oversight. Without such an evaluation, EPA does not know what oversight activities are most effective or necessary. Second, to enforce state class II requirements, under current agency regulations, EPA must approve and incorporate state program requirements and any changes to them into federal regulations through a rulemaking. EPA has not incorporated all such requirements and changes into federal regulations and, as a result, may not be able to enforce all state program requirements. Some EPA officials said that incorporating changes into federal regulations through the rulemaking process is burdensome and time-consuming. EPA has not, however, evaluated alternatives for a more efficient process to approve and incorporate state program requirements and changes into regulations. Without incorporating these requirements and changes into federal regulations, EPA cannot enforce them if a state does not take action or requests EPA’s assistance to take action.
For over 30 years, EPA and states have managed regulatory programs with safeguards that are designed to prevent contamination of underground sources of drinking water from the injection of fluids associated with oil and gas production. As domestic oil and gas production and the demand for underground injection wells continue to increase, EPA faces additional challenges maintaining sufficient oversight and enforcement of these different programs and requirements in a budget-constrained environment. States have been partners with EPA in managing their programs, yet face similar budgetary constraints. To meet its responsibilities to oversee and enforce class II program requirements, it is important that EPA ensures that state programs have information on risks to underground sources of drinking water posed by underground injection, that its oversight and enforcement are focused and efficient, and that it obtains sufficient information to monitor and report on the program nationally.
EESI Issue Brief on Government Climate Change Publications
There has been an outpouring of reports from both domestic and international governmental bodies supporting the existence, causes, and need for action concerning climate change. On this website are summaries of a selected number of these publications. Depending on the authoring body, each report has a varying focus, but they all support the common theme that climate change is happening, its causes are anthropogenic, and planning and action need to begin now to address current and future impacts. It is clear that water resources are closely connected to what happens in climate change, and for that reason the issue brief is important to all water resources specialists.
The issue brief (August 2014) has been prepared by the Environmental and Energy Study Institute (EESI), and is available at http://www.eesi.org/papers/view/summarizing-recent-governmental-climate-change-publications
Tracking the Source and Quantity of Nutrients to the Nation’s Estuaries
New maps and data tables that describe nutrient loading to major estuaries throughout the conterminous U.S. are now available online on the National Water-Quality Assessment (NAWQA) Program web page titled Tracking the Source and Quantity of Nutrients to the Nation's Estuaries. These new web pages describe the major sources and contributing areas of nutrients to 115 estuaries along the Atlantic Coast, Gulf of Mexico, and the Pacific Northwest coast and from 160 watersheds draining into the Great Lakes.
In addition to the new web pages, water resource managers interested in a particular stream, reservoir, or estuary can use the online, interactive SPARROW model Decision-Support System (DSS) to estimate how reductions in nutrient sources affect downstream nutrient loads at a stream outlet. A new reporting feature within the DSS provides summary information on the amounts and sources of nutrients from upstream states or major hydrologic regions. For instance, output from the new reporting feature shows the amount of nitrogen contributed from each of the 31 states that drain into the Gulf of Mexico from the Mississippi River Basin.
This combination of national maps and an online decision support system are provided to improve access to water-quality modeling information that can be used in the development of nutrient reduction strategies and inform nutrient policies across the Nation.
and Partners Release New Hydrologic Projections for Contiguous United States
WASHINGTON - The Bureau of Reclamation has released new hydrologic projections that will help local water managers answer questions about future climate, stream flow and water resources. This new scientific data uses the updated World Climate Research Program climate projections that have been scaled to a finer resolution (downscaled) for water management decision support systems.
"Reclamation is helping water managers prepare for the impacts of climate change with the release of this information, supporting the President's Climate Action Plan," Acting Reclamation Commissioner Lowell Pimley said. "Researchers and planners can use these future climate and hydrology projections to assess societal impacts and explore adaptation options."
The hydrologic data was derived from new downscaled climate projections using the Coupled Model Inter-comparison Project Phase 5 (CMIP5) data from the World Climate Research Program that was made available by Reclamation and collaborators in May 2013. To develop the new hydrologic projections, the group translated 97 of those downscaled CMIP5 climate projections into fine resolution projections of hydrology for the contiguous United States.
The new hydrology projections are available at http://bit.ly/1rwh1kS. Scientists and engineers can use this website to quickly access and download the new information.
The World Climate Research Program develops global climate projections through its CMIP roughly every five to seven years. Results from CMIP3 were released in 2007 and later used in Reclamation research and assessments including the 2011 SECURE Water Act Report and WaterSMART Basin Studies completed in the Colorado, Yakima and St. Mary - Milk River basins.
These new hydrology projections were developed by Reclamation, U.S. Army Corps of Engineers and National Corporation for Atmospheric Research in collaboration with Climate Analytics Group, Climate Central, Lawrence Livermore National Labs, Santa Clara University, Scripps Institution of Oceanography and U.S. Geological Survey.

Tortajada, Cecilia, Water Resources: An Evolving Landscape, Chapter 26, 2013.
This chapter presents the history of thinking on water resources and how it has evolved over time. It analyzes paradigms proposed by the international community during the last half century in light of their decisive influence on the content (though not the implementation) of water policies in virtually all developed and developing countries. While paradigms have been an important part of global thinking, at the local level they have represented more of a concept than a reality. This may be why, in the second decade of the twenty-first century, formulation and implementation of efficient policies and management practices benefiting humankind and the environment have still not been achieved.
Gleick, Peter H., Roadmap for Sustainable Water Resources in Southwestern North America, Proceedings of the National Academy of Sciences, Washington, 2010.
The management of water resources in arid and semiarid areas has long been a challenge, from ancient Mesopotamia to the modern southwestern United States. As our understanding of the hydrological and climatological cycles has improved, and our ability to manipulate the hydrologic cycle has increased, so too have the challenges associated with managing a limited natural resource for a growing population. Modern civilization has made remarkable progress in water management in the past few centuries. Burgeoning cities now survive in desert regions, relying on a mix of simple and complex technologies and management systems to bring adequate water and remove wastewater. These systems have permitted agricultural production and urban concentrations to expand in regions previously thought to have inadequate moisture.
However, evidence is also mounting that our current management and use of water is unsustainable. Physical, economic, and ecological limits constrain the development of new supplies and additional water withdrawals, even in regions not previously thought vulnerable to water constraints. New kinds of limits are forcing water managers and policy makers to rethink previous assumptions about population, technology, regional planning, and forms of development. In addition, new threats, especially the challenges posed by climatic changes, are now apparent. Sustainably managing and using water in arid and semiarid regions such as the southwestern United States will require new thinking about water in an interdisciplinary and integrated way. The good news is that a wide range of options suggest a roadmap for sustainable water management and use in the coming decades.
The Water-Energy Nexus: Challenges and Opportunities, U.S. Department of Energy, 2014.
Energy and water systems are interdependent.
We cannot assume the future is like the past in terms of climate, technology, and the evolving decision landscape.
Water scarcity, variability, and uncertainty are becoming more prominent, potentially leading to vulnerabilities of the U.S. energy system.
It is time for a more integrated approach to address the challenges and opportunities of the water-energy nexus.
DOE has strong expertise in technology, modeling, analysis, and data that can contribute to understanding the issues and solutions across the entire nexus.
Collaboration with DOE’s many current and potential partners is crucial.

Water is an essential natural resource that impacts all aspects of life: Clean and abundant supplies of water are vital for supporting the production of food, public health, industrial and energy development, and a healthy environment. Water is an integral part of energy extraction, production, and generation. It is used directly in hydroelectric power generation and is used extensively for thermoelectric power plant cooling and emissions control. Water is also used for energy resource extraction such as gas shale fracking and development, biofuels production, coal and uranium mining and processing, as well as for oil and natural gas refining and energy resource transportation.
Government Accountability Office, Freshwater: Supply Concerns Continue, and Uncertainties Complicate Planning, Report to Congressional Requestors, GAO-14-430, May 2014.
The nation’s water bodies have long supplied Americans with abundant freshwater, but recent events, such as the ongoing California drought, have focused attention on competing demands for this limited resource. In the United States, the states are primarily responsible for managing freshwater resources, and many federal agencies influence states’ management decisions. In 2003, GAO issued a report providing an overview of trends in freshwater availability and use, as well as states’ views on ways the federal government could assist states to help meet future water management challenges.
GAO was asked to report on changes since 2003. This report examines (1) issues related to freshwater availability and use; (2) expectations for water availability and use over the next 10 years and how these expectations may affect water planning; (3) steps, if any, states have taken to manage freshwater resources; and (4) actions, if any, federal agencies have taken to support management of freshwater availability and use and perspectives from state water managers, experts, and literature on what the federal government can do to enhance its support. GAO conducted a survey of 50 state water managers with a response rate of 100 percent. GAO also reviewed reports and documents from entities, such as federal agencies and environmental organizations, and interviewed federal officials and experts, including environmental and industry officials, to understand freshwater issues across the nation. GAO is not making recommendations

OVERVIEW AND REPORT FINDINGS
CLIMATE CHANGE IMPACTS IN THE UNITED STATES
These findings distill important results that arise from this National Climate Assessment. They do not represent a full summary of all of the chapters’ findings, but rather a synthesis of particularly noteworthy conclusions.
1. Global climate is changing and this is apparent across the United States in a wide range of observations. The global warming of the past 50 years is primarily due to human activities, predominantly the burning of fossil fuels.
Many independent lines of evidence confirm that human activities are affecting climate in unprecedented ways. U.S. average temperature has increased by 1.3°F to 1.9°F since record keeping began in 1895; most of this increase has occurred since about 1970. The most recent decade was the warmest on record. Because human-induced warming is superimposed on a naturally varying climate, rising temperatures are not evenly distributed across the country or over time. See page 18.
2. Some extreme weather and climate events have increased in recent decades, and new and stronger evidence confirms that some of these increases are related to human activities.
Changes in extreme weather events are the primary way that most people experience climate change. Human-induced climate change has already increased the number and strength of some of these extreme events. Over the last 50 years, much of the United States has seen an increase in prolonged periods of excessively high temperatures, more heavy downpours, and in some regions, more severe droughts. See page 24.
3. Human-induced climate change is projected to continue, and it will accelerate significantly if global emissions of heat-trapping gases continue to increase.
Heat-trapping gases already in the atmosphere have committed us to a hotter future with more climate-related impacts over the next few decades. The magnitude of climate change beyond the next few decades depends primarily on the amount of heat-trapping gases that human activities emit globally, now and in the future. See page 28.
4. Impacts related to climate change are already evident in many sectors and are expected to become increasingly disruptive across the nation throughout this century and beyond.
Climate change is already affecting societies and the natural world. Climate change interacts with other environmental and societal factors in ways that can either moderate or intensify these impacts. The types and magnitudes of impacts vary across the nation and through time. Children, the elderly, the sick, and the poor are especially vulnerable. There is mounting evidence that harm to the nation will increase substantially in the future unless global emissions of heat-trapping gases are greatly reduced.24 See page 32.
5. Climate change threatens human health and well-being in many ways, including through more extreme weather events and wildfire, decreased air quality, and diseases transmitted by insects, food, and water.
Climate change is increasing the risks of heat stress, respiratory stress from poor air quality, and the spread of waterborne diseases. Extreme weather events often lead to fatalities and a variety of health impacts on vulnerable populations, including impacts on mental health, such as anxiety and post-traumatic stress disorder. Large-scale changes in the environment due to climate change and extreme weather events are increasing the risk of the emergence or reemergence of health threats that are currently uncommon in the United States, such as dengue fever. See page 34.
6. Infrastructure is being damaged by sea level rise, heavy downpours, and extreme heat; damages are projected to increase with continued climate change.
Sea level rise, storm surge, and heavy downpours, in combination with the pattern of continued development in coastal areas, are increasing damage to U.S. infrastructure including roads, buildings, and industrial facilities, and are also increasing risks to ports and coastal military installations. Flooding along rivers, lakes, and in cities following heavy downpours, prolonged rains, and rapid melting of snowpack is exceeding the limits of flood protection infrastructure designed for historical conditions. Extreme heat is damaging transportation infrastructure such as roads, rail lines, and airport runways. See page 38.
7. Water quality and water supply reliability are jeopardized by climate change in a variety of ways that affect ecosystems and livelihoods.
Surface and groundwater supplies in some regions are already stressed by increasing demand for water as well as declining runoff and groundwater recharge. In some regions, particularly the southern part of the country and the Caribbean and Pacific Islands, climate change is increasing the likelihood of water shortages and competition for water among its many uses. Water quality is diminishing in many areas, particularly due to increasing sediment and contaminant concentrations after heavy downpours. See page 42.
8. Climate disruptions to agriculture have been increasing and are projected to become more severe over this century.
Some areas are already experiencing climate-related disruptions, particularly due to extreme weather events. While some U.S. regions and some types of agricultural production will be relatively resilient to climate change over the next 25 years or so, others will increasingly suffer from stresses due to extreme heat, drought, disease, and heavy downpours. From mid-century on, climate change is projected to have more negative impacts on crops and livestock across the country – a trend that could diminish the security of our food supply. See page 46.
9. Climate change poses particular threats to Indigenous Peoples’ health, well-being, and ways of life.
Chronic stresses such as extreme poverty are being exacerbated by climate change impacts such as reduced access to traditional foods, decreased water quality, and increasing exposure to health and safety hazards. In parts of Alaska, Louisiana, the Pacific Islands, and other coastal locations, climate change impacts (through erosion and inundation) are so severe that some communities are already relocating from historical homelands to which their traditions and cultural identities are tied. Particularly in Alaska, the rapid pace of temperature rise, ice and snow melt, and permafrost thaw are significantly affecting critical infrastructure and traditional livelihoods. See page 48.
10. Ecosystems and the benefits they provide to society are being affected by climate change. The capacity of ecosystems to buffer the impacts of extreme events like fires, floods, and severe storms is being overwhelmed.
Climate change impacts on biodiversity are already being observed in alteration of the timing of critical biological events such as spring bud burst and substantial range shifts of many species. In the longer term, there is an increased risk of species extinction. These changes have social, cultural, and economic effects. Events such as droughts, floods, wildfires, and pest outbreaks associated with climate change (for example, bark beetles in the West) are already disrupting ecosystems. These changes limit the capacity of ecosystems, such as forests, barrier beaches, and wetlands, to continue to play important roles in reducing the impacts of these extreme events on infrastructure, human communities, and other valued resources. See page 50.
11. Ocean waters are becoming warmer and more acidic, broadly affecting ocean circulation, chemistry, ecosystems, and marine life.
More acidic waters inhibit the formation of shells, skeletons, and coral reefs. Warmer waters harm coral reefs and alter the distribution, abundance, and productivity of many marine species. The rising temperature and changing chemistry of ocean water combine with other stresses, such as overfishing and coastal and marine pollution, to alter marine-based food production and harm fishing communities. See page 58.
12. Planning for adaptation (to address and prepare for impacts) and mitigation (to reduce future climate change, for example by cutting emissions) is becoming more widespread, but current implementation efforts are insufficient to avoid increasingly negative social, environmental, and economic consequences.
Actions to reduce emissions, increase carbon uptake, adapt to a changing climate, and increase resilience to impacts that are unavoidable can improve public health, economic development, ecosystem protection, and quality of life. See page 62.

Carter, Nicole T., Energy-Water Nexus: The Energy Sector’s Water Use, Congressional Research Service, 7-5700, R43199, 2013.
Water and energy are critical resources that are reciprocally linked; this interdependence is often described as the water-energy nexus. Meeting energy-sector water needs, which are often large, depends upon the local availability of water for fuel production, hydropower generation, and thermoelectric power plant cooling. The U.S. energy sector’s use of water is significant in terms of water withdrawals and water consumption. In 2005, thermoelectric cooling represented 41% of water withdrawn nationally, and 6% of water consumed nationally. The majority of the anticipated increase in water consumption by 2030 is attributed to domestic biofuel and oil and gas production. Policy makers at the federal, state, and local levels are faced with deciding whether to respond to the growing water needs of the energy sector, and if so, which policy levers to use (e.g., tax incentives, loan guarantees, permits, regulations, planning, or education). Many U.S. energy sector water decisions are made by private entities, and state entities have the majority of the authority over water use and allocation policies and decisions.
Conventional hydropower accounts for approximately 8% of total U.S. net electricity generation, and more than 80% of U.S. electricity is generated at thermoelectric facilities that depend on cooling water. Water availability issues, such as regional drought, low flow, or intense competition for water can curtail hydroelectric and thermoelectric generation. An assessment of the drought vulnerability of electricity in the western United States found broad resiliency, while also identifying the Pacific Northwest and the Texas grid at higher risk. Future withdrawals associated with electric generation may grow slightly, remain steady, or decline depending on a number of factors. These include reduced generation from facilities using once-through cooling because of compliance with proposed federal cooling water intake regulations or shifts in how electricity is generated (e.g., less from coal and more from wind and natural gas).
Energy choices represent complex tradeoffs; water use and wastewater byproducts are two of many factors to consider when making energy choices. For many policymakers, concerns other than water.—low-cost reliable energy, energy independence and security, climate change mitigation, public health, and job creation.—are more significant drivers of their positions on energy policies.
Copeland, Claudia, Energy-Water Nexus: The Water Sector’s Energy Use, Congressional Research Service, 7-5700, R43200, 2013.
Water and energy are resources that are reciprocally and mutually linked, because meeting energy needs requires water, often in large quantities, for mining, fuel production, hydropower, and power plant cooling, and energy is needed for pumping, treatment, and distribution of water and for collection, treatment, and discharge of wastewater. This interrelationship is often referred to as the energy-water nexus, or the water-energy nexus. There is growing recognition that .“saving water saves energy..” Energy efficiency initiatives offer opportunities for delivering significant water savings, and likewise, water efficiency initiatives offer opportunities for delivering significant energy savings. In addition, saving water also reduces carbon emissions by saving energy otherwise generated to move and treat water.
This report provides background on energy for facilities that treat and deliver water to end users and also dispose of and discharge wastewater. Energy use for water is a function of many variables, including water source (surface water pumping typically requires less energy than groundwater pumping), treatment (high ambient quality raw water requires less treatment than brackish or seawater), intended end-use, distribution (water pumped long distances requires more energy), amount of water loss in the system through leakage and evaporation, and level of wastewater treatment (stringency of water quality regulations to meet discharge standards). Likewise, the intensity of energy use of water, which is the relative amount of energy needed for a task such as pumping water, varies depending on characteristics such as topography (affecting groundwater recharge), climate, seasonal temperature, and rainfall. Most of the energy used for water-related purposes is in the form of electricity. Estimates of water-related energy use range from 4% to perhaps 13% of the nation’s electricity generation, but regional differences can be significant. In California, for example, as much as 19% of the state’s electricity consumption is for pumping, treating, collecting and discharging water and wastewater.
Topics for research to better understand water-related energy use include studies of energy demands for water at local, regional, and national scales; development of consistent data collection methodology to track water and energy data across all sectors; development and implementation of advanced technologies that save energy and water; and analysis of incentives, disincentives, and lack of incentives to investing in cost-effective energy or water efficiency measures.

In 1950 the global population was just over 2.5 billion. Now, in 2013, it is around 7 billion. Although population growth is slowing, the world is projected to have around 9.6 billion inhabitants by 2050. Most of the population increase will be in developing countries where food is often scarce, and land and water are under pressure. To feed the global population in 2050 the world will have to produce more food without significantly expanding the area of cultivated land and, because of competition between a greater number of water users, with less freshwater. On top of land and water constraints, food producers face climatic and other changes which will affect food production.
There remains great uncertainty as to how climate change will affect any given locality, but it seems likely that it will have a profound effect on water resources. Projected rises in average temperature, more extreme temperatures, and changes in precipitation patterns are likely to alter the amounts and distribution of rainfall, ice and snow melt, soil moisture, and river and groundwater flows.
Climate Change, Energy Infrastructure Risks and Adaptation Efforts, Report to Congressional Requestors, Government Accountability Office, GAO-14-74, 2014.
GAO was asked to examine the vulnerability of the nation’s energy infrastructure to climate change impacts. This report examines: (1) what is known about potential impacts of climate change on U.S. energy infrastructure; (2) measures that can reduce climate-related risks and adapt energy infrastructure to climate change; and (3) the role of the federal government in adapting energy infrastructure and adaptation steps selected federal entities have taken. GAO reviewed climate change assessments; analyzed relevant studies and agency documents; and interviewed federal agency officials and industry stakeholders, including energy companies at four sites that have implemented adaptive measures.
Dörendahl, Esther I. (2013): Boundary work and water resources: Towards improved management and research practice?, ZEF Working Paper Series, No. 122
This paper explores the potential of ‘boundary work’ perspectives for enhancing current approaches in water resources management and research with a focus on developing countries. Boundary work thinking is analyzed in the context of three currently leading approaches for water and natural resources management, i.e. Integrated Water Resources Management, Adaptive Management, and the Ecosystem Approach. Given the political dimension of water resources management, questions of governance are merged into the boundary work perspective. The paper introduces the Boundary Work framework as developed by Mollinga, discusses the potential of the framework for enhancing water resources management and research practice and proposes amendments to the framework.
G. Pegram, Y. Li, T. Le. Quesne, R. Speed, J. Li, and F. Shen. 2013. River basin planning: Principles, procedures and approaches for strategic basin planning. Paris, UNESCO.
Water provides the lifeblood of natural systems, societies and economies. People have lived near and on rivers, lakes, wetlands and deltas for many centuries. Rivers provide a multitude of services such as water supply, waste assimilation, fisheries, energy production, flood attenuation, spiritual, cultural and recreational benefits, and the habitat that supports a wide range of ecosystems.
It is precisely because water resources provide so many functions that planning for their use is so complex. The demands on rivers increasingly exceed their natural capabilities, resulting in over abstraction, pollution, alien infestation, floodplain alteration and habitat destruction. These failures are usually the consequence of poor decision-making, inadequate management and inappropriate planning. Effective basin planning is the starting point for sustainable management of river basins.
The practice of basin planning has developed over time in response to the changing demands placed on river systems by societies, and the changing conditions of rivers. The first attempt to manage the hydrological cycle in a coherent way was undertaken in China about two millennia ago. The concept of the river basin as a unit of management became more widely established in the middle of the nineteenth century. It was the massive water resources infrastructure development that took place across the world between 1920 and 1970 that ushered in a phase of ‘water resources development planning’. At the core of these initiatives was the view that river basin planning is primarily a technical activity that can be undertaken by engineers, with the objective of optimizing the benefits derived from infrastructure development and operation.
During the 1970s and 1980s it became evident that engineering solutions were no longer adequate to address the multifaceted problems of management, particularly the trade-offs between competing interests and values. The development of new approaches was influenced by a number of emerging trends in the water and environmental sectors:
▶ The exhaustion of options for technical, engineering solutions to problems. For example, it was no longer possible to construct new infrastructure to meet growing demand for water.
▶ The recognition of the importance of functioning aquatic ecosystems, and the rapid global decline in the health of freshwater ecosystems.
▶ The increasing costs associated with water supply and waste management.
▶ A desire for more decentralized management and greater stakeholder engagement.
These trends led to new approaches to water resources management and basin planning. These approaches were first articulated in the 1990s in the concept of integrated water resources management (IWRM). Many countries have since embarked on policy and law reforms, in most cases embracing the suite of approaches typically associated with IWRM, including basin planning. While enabling important progress, these reforms have highlighted some of the limitations of IWRM. These have included recognition of the approaches to planning in the context of limited information and imperfect institutions, the ongoing importance of infrastructure, the development of approaches to basin-scale environmental management, and decision-making in societies undergoing rapid economic and social change. In this context, more strategic approaches to basin planning and management are developing, building on the lessons from implementation in recent decades.

Historically, federal conservation programs have focused on solving environmental and natural resource problems on individual farms. While improvements have been made in water quality and wildlife habitat at the farm scale, landscape-scale environmental benefits in streams, lakes, and bays, for example, are less commonly documented. Excess nutrients (nitrogen, N, and phosphorus, P) continue to impair thousands of waterways, and eutrophication leads to hypoxia (low oxygen levels that harm aquatic life) or dead zones in water bodies around the country. This report focuses on the Mississippi River Basin.

More than a decade ago, EPRI identified water availability constraints as a major issue facing current operations and future development of the electric power sector in the United States and internationally. As a result, EPRI initiated research to assess and reduce both current and future vulnerabilities to water shortages. This report derives and applies algorithms for calculating water consumption by the U.S. electric power, municipal, and agricultural sectors. Using the most recent available national data sets, a national water consumption budget is calculated based on the spatial resolution of U.S. counties as well as United States Geological Survey (USGS) medium-sized watersheds.
Web Site: Abrupt Impacts of Climate Change: Anticipating Surprises, Climate Change at the National Academies, 2014.
Both abrupt changes in the physical climate system and steady changes in climate that can trigger abrupt changes in other physical, biological, and human systems present possible threats to nature and society. Abrupt change is already underway in some systems, and large scientific uncertainties about the likelihood of other abrupt changes highlight the need for further research. However, with recent advances in understanding of the climate system, some potential abrupt changes once thought to be imminent threats are now considered unlikely to occur this century. This report summarizes the current state of knowledge on potential abrupt changes to the ocean, atmosphere, ecosystems, and high latitude areas, and identifies key research and monitoring needs. The report calls for action to develop an abrupt change early warning system to help anticipate future abrupt changes and reduce their impacts.

On January 30th, EPA Administrator Gina McCarthy announced phase II of the National Stormwater Calculator Climate Assessment Tool. The tool provides decision-makers with an easy-to-use, customizable resource to identify and incorporate green infrastructure and low impact development techniques to reduce storm water runoff. The updated tool includes changes in seasonal precipitation levels; the effects of more frequent, high-intensity storms; and changes in evaporation rates based on climate change scenarios validated by the Intergovernmental Panel on Climate Change. The Stormwater Calculator and Climate Assessment Tool package was originally mentioned as part of the President’s Climate Action Plan. The announcement was made during a keynote speech at the 14thNational Conference and Global Forum on Science, Policy, and the Environment.
Ekness, Paul A., Ecohydrologic Impacts of Climate and Land Use Changes on Watershed Systems: A Multi-Scale Assessment for Policy (2013). Open Access Dissertations. Paper 789.
Maintaining flows and quality of water resources is critical to support ecosystem services and consumptive needs. Understanding impacts of changes in climate and land use on ecohydrologic processes in a watershed is vital to sustaining water resources for multiple uses. This study completes a continental and regional scale assessment using statistical and simulation modeling to investigate ecohydrologic impacts within watershed systems.
Watersheds across the continental United States have diverse hydrogeomorphic characters, mean temperatures, soil moistures, precipitation and evaporation patterns that influence runoff processes. Changes in climate affect runoff by impacting available soil moisture, evaporation, precipitation and vegetative patterns.
scale runoff is affected by soil moisture and vegetative cover. Cover crops,
low tillage farm practices and natural vegetation contribute to less runoff. Developing
policies that encourage protection of soil structure could minimize runoff and aid in
maintaining sustainable water resources. Best Management Practices and Low impact
development at the national level with continued stormwater legislation
sustainable land use policy will improve water quantity and quality.

With the topic of The Future of Water Resources in the United States and 18 articles on topics ranging from water law and pricing to floods, drought management and agriculture, and authors such as Gerald Galloway, Debra Knopman, Ben Grumbles and Brenda Bateman, this is already being called one of Water Resources IMPACT's best issues ever.
Climate Change: Federal Efforts Underway to Assess Water Infrastructure Vulnerabilities and Address Adaptation Challenges, Government Accountability Office, GAO-14-23, Nov. 2013.
The effects of climate change on water resources have already been observed and are expected to continue. The Corps and Reclamation own and operate key water resource management infrastructure, such as dams and reservoirs. Adaptation—adjustments in natural or human systems to a new or changing environment that exploits beneficial opportunities or moderates negative effects—can be used to help manage the risks to vulnerable resources. In 2009, a law—commonly referred to as the SECURE Water Act—and a presidential executive order directed federal agencies to address the potential impacts of climate change.
Clean Water Act: Changes Needed If Key EPA Program Is to Help Fulfill the Nation’s Water Quality Goals, Government Accountability Office, GAO-14-80, Dec. 2013.
GAO was asked to examine the TMDL program, specifically (1) EPA’s and states’ responsibilities in developing and implementing TMDLs, (2) what is known about the status of long-established TMDLs, (3) the extent to which such TMDLs contain features key to attaining water quality standards, and (4) the extent to which TMDLs exhibit factors that facilitate effective implementation. GAO asked water resource experts to review a random sample of 25 long-established TMDLs and surveyed state officials who are responsible for implementing a representative sample of 191 long-established TMDLs.

The year 2013 ties with 2003 as the fourth warmest year globally since records began in 1880. The annual global combined land and ocean surface temperature was 0.62°C (1.12°F) above the 20th century average of 13.9°C (57.0°F). This marks the 37th consecutive year (since 1976) that the yearly global temperature was above average. Currently, the warmest year on record is 2010, which was 0.66°C (1.19°F) above average. Including 2013, 9 of the 10 warmest years in the 134-year period of record have occurred in the 21st century. Only one year during the 20th century—1998—was warmer than 2013.

FACT SHEET: Climate Adaptation at the Federal Level, by Rachel Hampton and John-Michael Cross, Environmental and Energy Study Institute, Jan. 2014.
Climate change adaptation is a risk-management strategy characterized by adjustments to natural or human systems in response to actual or expected climate change. Climate adaptation (or resiliency) efforts can vary widely based on the needs of a region, but they commonly include better climate information and decision-making tools, new building and infrastructure standards, and infrastructure modifications that improve resiliency to storm water or extreme temperatures.
Due to concerns over national climate vulnerability and unavoidable increases in climate risk in the coming decades, policymakers have expanded their focus beyond climate mitigation to include resiliency efforts. Many efforts are ongoing at the state and local level. Although progress by the federal government has lagged, strides have been made in the last few years. Action at the federal level can serve to provide guidelines and resources to states and cities, promote collaboration, and improve financing availability. This fact sheet explores federal climate resiliency efforts, the majority of which are in progress.
Hightower, Mike, Danny Reible, and Michael Webber, Workshop Report: Developing a Research Agenda for the Energy-Water Nexus, Sandia National Laboratory, Texas Tech University, and University of Texas, for the National Science Foundation, 2013.
The energy-water nexus has attracted public scrutiny because of the concerns about their interdependence and the possibility for cascading vulnerabilities from one system to the other. There are trends toward more water intensive energy, (such as biofuels, unconventional oil and gas production, and regulations driving more water consumption for thermoelectric power production) and more energy intensive water (such as desalination, or deeper ground water pumping and production). To address these and other concerns, the National Science Foundation sponsored a workshop in June 2013 to bring together technical, academic, and industry experts from across the country to help develop a research agenda. The results of the workshop are presented in this report, which includes the highest priority research directions identified, plus supporting materials.

The California Water Plan has been under development for some years. The most recent effort was in 2013, with collaborative work of the University of California at Davis, the California Department of Water Resources, and the U.S. Environmental Protection Agency. A good deal of the plan relies on the use of indicators and analyses of water sustainability. See the following link for more information:
In addition, the 2013 report can be found as follows:
Shilling, Fraser, The California Water Sustainability Indicators Framework: Draft Final Report, University of California, Davis, 2013.
The Water Sustainability Indicators Framework grew out of regional projects developing indicators for water and watershed condition. The California Water Plan Update 2013 team decided to incorporate sustainability indicators into the Update in response to recommendations from the 2009 Update advisory process. This report describes the work completed in two phases by the UC Davis team between 2011 and 2013. The first phase (henceforth Phase I) involved developing an analytical framework and approach (henceforth Framework) for developing and evaluating indicators. The second phase (henceforth Phase II) involved pilot testing the Framework at the state and regional scales and development of a web-based reporting and decision-support tool. The report is divided among these two phases, with the intent that the bulk of the report would be included in the California Water Plan Update 2013, Volume IV – Technical Appendices.
The Phase I report describes the progressive development and use of sustainability indicators from vision and goal setting to reporting and knowledge-building. It describes the disaggregation of goals into measurable objectives in the presence of tribe, stakeholder, and agency contributions, and the identification of indicators corresponding to the goals and objectives. It describes the use of a novel method for measuring sustainability performance that involves comparing condition to defined desired and undesired targets. The scores that result from the comparison can be reported at various scales, depending on the fineness and extent of the data. Finally, the Framework describes reporting conditions and trends in various formats, including a report card in narrative, tabular, and/or map form.
The Phase II report describes the testing of the Framework at the state scale and the region scale. The statewide reporting is primarily at the Hydrologic Region (HR) scale, with additional reporting at finer scales where possible, based on the US Geological Survey’s Hydrologic Unit Code (HUC) system for watershed classification. The Santa Ana Watershed Protection Authority (SAWPA) region was chosen after consideration of multiple candidate regions because of complexity of the region, availability of a stakeholder process, and capacity of SAWPA to partner with the UC Davis team. The Council for Watershed Health assisted with this regional project, under contract with SAWPA.
U.S. EPA. Watershed Management Optimization Support Tool (WMOST) v1: User Manual and Case Study Examples. US EPA Office of Research and Development, Washington, DC, EPA/600/R-13/174, 2013.
The Watershed Management Optimization Support Tool (WMOST) is intended to be used as a screening tool as part of an integrated watershed management process such as that described in EPA’s watershed planning handbook (EPA 2008).1 The objective of WMOST is to serve as a public-domain, efficient, and user-friendly tool for local water resources managers and planners to screen a wide-range of potential water resources management options across their watershed or jurisdiction for cost-effectiveness as well as environmental and economic sustainability (Zoltay et al 2010).
Examples of options that could be evaluated with the tool include projects related to stormwater, water supply, wastewater and water-related resources such as Low-Impact Development (LID) and land conservation. The tool is intended to aid in evaluating the environmental and economic costs, benefits, trade-offs and co-benefits of various management options. In addition, the tool is intended to facilitate the evaluation of low impact development (LID) and green infrastructure as alternative or complementary management options in projects proposed for State Revolving Funds (SRF).
WMOST is a screening model that is spatially lumped with a daily or monthly time step. The model considers water flows but does not yet consider water quality. The optimization of management options is solved using linear programming. The target user group for WMOST consists of local water resources managers, including municipal water works superintendents and their consultants. This document includes a user guide and presentation of two case studies as examples of how to apply WMOST. Theoretical documentation is provided in a separate report (EPA/600/R-13/151).
U.S. EPA. BASINS (Better Assessment Science Integrating Point & Non-Point Sources), EPA Web Site, 2013.
Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) is a multipurpose environmental analysis system designed to help regional, state, and local agencies perform watershed- and water quality-based studies.
It was developed by the U.S. Environmental Protection Agency to assist in watershed management and TMDL development by integrating environmental data, analysis tools, and watershed and water quality models.
A geographic information system (GIS) provides the integrating framework for BASINS. GIS organizes spatial information so it can be displayed as maps, tables, or graphics. GIS allows the user to analyze landscape information and display relationships among data. Through the use of GIS, BASINS has the flexibility to display and integrate a wide range of information (e.g., land use, point source discharges, and water supply withdrawals) at a scale chosen by the user.
Bosshaq, M.R., et al, Measuring Indicators and Determining Factors Affecting Sustainable Agricultural Development in Rural Areas – A Case Study of Ravansar, Iran, International Journal of AgriScience, Vol. 2(6): 550-557, 2012.
In many developing countries continuous economic growth depends on rural regeneration by means of socio-political development. It is therefore crucial to ensure sustainability in the agricultural sector in terms of levels of production and local employment in those countries that depend on food and fiber production. This paper aims to evaluate sustainability indicators in the Ravansar area and Iran in general.
The methodology used in this study was by collection of primary data and field observations. Data interpretation was done with a descriptive statistical method. Samples for statistics were taken from heads of rural households in Ravansar villages. Subjects were randomly selected for inclusion in samples and the questionnaire was evaluated by use of Cochran's formula. The sample consisted of 188 cases. The Cronbach alpha coefficient was used to make calculations that determined the reliability of questionnaires, for which there three parts with evaluation percentages of 0.72, 0.73, 0.79.
Results showed that 38.70 percent of indicators were in the unstable group, 22.58 percent in the somewhat stable group and 38.70 percent were in the stable group. Results of the regression analysis based on the stepwise method showed that the four variables of education level, household income, average land size, and total land ownership had a 56% influence on agricultural sustainability of the Ravansar rural region.
Alley, W.M., Evenson, E.J., Barber, N.L., Bruce, B.W., Dennehy, K.F., Freeman, M.C., Freeman, W.O., Fischer, J.M., Hughes, W.B., Kennen, J.G., Kiang, J.E., Maloney, K.O., Musgrove, MaryLynn, Ralston, Barbara, Tessler, Steven, and Verdin, J.P., 2013, Progress toward establishing a national assessment of water availability and use: U.S. Geological Survey Circular 1384, 34 p.
The Omnibus Public Land Management Act of 2009 (Public Law 111-11) was passed into law on March 30, 2009. Subtitle F, also known as the SECURE Water Act, calls for the establishment of a “national water availability and use assessment program” within the U.S. Geological Survey (USGS). A major driver for this recommendation was that national water availability and use have not been comprehensively assessed since 1978.
This report fulfills a requirement to report to Congress on progress in implementing the national water availability and use assessment program, also referred to as the National Water Census. The SECURE Water Act authorized $20 million for each of fiscal years (FY) 2009 through 2023 for assessment of national water availability and use. The first appropriation for this effort was $4 million in FY 2011, followed by an appropriation of $6 million in FY 2012.
The National Water Census synthesizes and reports information at the regional and national scales, with an emphasis on compiling and reporting the information in a way that is useful to states and others responsible for water management and natural-resource issues. The USGS works with Federal and non-Federal agencies, universities, and other organizations to ensure that the information can be aggregated with other types of water-availability and socioeconomic information, such as data on food and energy production. To maximize the utility of the information, the USGS coordinates the design and development of the effort through the Federal Advisory Committee on Water Information.
A National Water Census is a complex undertaking, particularly because there are major gaps in the information needed to conduct such an assessment. To maximize progress, the USGS engaged stakeholders in a discussion of priorities and leveraged existing studies and program activities to enhance efforts toward the development of a National Water Census.
Harich, Jack and Philip Bangerter, Finding True North at the U.S. EPA With Root Cause Analysis, Australian Centre for Sustainable Business & Development, University of Southern Queensland, 2013.
In 2010 the U.S. Environmental Protection Agency (EPA) underwent a fundamental change in mission by “recognition that the goal of sustainability is our ‘true north.’ ” Subsequently in 2011, at the EPA’s request, the National Research Council completed a study known as the “Green Book.” Its purpose was to “provide an operational framework for integrating sustainability as one of the key drivers within the regulatory responsibilities of EPA.” The book describes the framework and recommends that the “EPA should adopt or adapt the comprehensive Sustainability Framework proposed in Figure S-1.”
This paper analyzes the Sustainability Framework and concludes that as presently designed it is not capable of achieving its stated goal. The steps and tools described in the Green Book are for solution “assessment and management.” Assessment is inspection, so this is an inspection driven process. It will tend to drive research toward the same class of popular solutions that for over forty years has failed to solve the sustainability problem because popular solutions do not resolve root causes. Furthermore, as this paper explains, you cannot inspect quality in. You can only build it into the product in the first place.
To fix these flaws and allow the EPA to “adapt” the Green Book framework so that it has a high probability of success, this paper presents the Quality Driven Framework. This framework, as well as most of the main points in this paper, has broad applicability to any environmental agency, not just the U.S. EPA.
FUTURE CONFERENCE: Shale Development and Hydraulic Fracturing, Capturing Unconventional Opportunities, American Society of Mechanical Engineers, San Diego, March 17-19, 2014.
Great Lakes Restoration Initiative (GLRI), Report to Congressional Requestors, Government Accountability Office, GAO-13-797, Sept. 2013.
Approximately $1.3 billion has been appropriated to the GLRI, created in fiscal year 2010, which an interagency Task Force of 11 federal agencies, chaired by the EPA Administrator, oversees. In 2010, the Task Force issued an Action Plan for fiscal years 2010 to 2014 to develop a comprehensive approach to restoring the health of the Great Lakes ecosystem. GAO was asked to review the GLRI. This report examines (1) how the GLRI is implemented by the Task Force agencies and other stakeholders, (2) the methods that EPA has in place to assess GLRI progress, (3) the progress identified by the Task Force agencies and nonfederal stakeholders, and (4) the views of nonfederal stakeholders on factors, if any, that may affect or limit GLRI progress. GAO analyzed the Action Plan, surveyed 205 non-federal recipients of GLRI funding, and interviewed Task Force agency officials and nonfederal stakeholders.
Richter, Brian D., et al, Tapped Out: How Can Cities Secure Their Water Future? Water Policy 15, 335-363, International Water Association, 2013.
Cities around the world are struggling to access additional water supplies to support their continued growth because their freshwater sources are becoming exhausted. Half of all cities with populations greater than 100,000 are located in water-scarce basins, and in these basins agricultural water consumption accounts for more than 90% of all freshwater depletions. In this paper we review the water development histories of four major cities: Adelaide, Phoenix, San Antonio and San Diego. We identify a similar pattern of water development in these cities, which begins with the exhaustion of local surface and groundwater supplies, continues with importation of water from other basins, and then turns to recycling of wastewater or storm water, or desalination of either seawater or brackish groundwater. Demand management through water conservation has mitigated, to varying degrees, the timing of water-system expansions and the extent to which cities rely on new sources of supply. This typical water development pattern in cities is undesirable from a sustainability perspective, as it is usually associated with serious ecological and social impacts as well as sub-optimal cost effectiveness. We highlight case examples and opportunities to invest in water conservation measures, particularly through urban–rural partnerships under which cities work with farmers to implement irrigation conservation measures, thereby freeing up water for ecological restoration and use by cities.
Bhatti, Asif M., et al, Water Resources Management: Pathways for Sustainable Economic Growth and Poverty Eradication, Society for Social Management Systems, 2012.
Water is essential not only for sustaining quality of life on the earth, but also for economic growth and poverty eradication. Due to rapid increase in population, the demand for water will increase over time. The nations that are well endowed in fresh water resources have an economic advantage over those less fortunate. Water resources management is a cost effective strategy; contributing to the economic prosperity and poverty reduction through several pathways, while strengthening systems and capacity for longer-term climate risk management. The access to safe and adequate water improves health, fulfills multiple needs of households, contribute to food and fiber production and poverty elimination. The prime purpose of the present paper is to enhance the understanding of the factors that influence water demand by deeply examining the water use in domestic, agricultural and industrial sectors in Pakistan. The driving forces and key issues, related to socio-economic development, that influence the future water availability and demand are also examined. Pakistan is a country that is facing a water crisis not because of physical scarcities of the resources, but because of lack of knowledge, experience, technology and co-ordination among different institutions. The empirical evidence shows that better management coupled with effective policy, intensified political will, appropriate investments, awareness, climatic change adoption and institutional strengthening are promising pathways for sustainable water resources management. In order to meet the water demand for environment, economic and people’s life, there is scope for significant improvement in the efficiency of water utilization, which if achieved should enhance the overall sustainability.
The Importance of Water to the U.S. Economy, Office of Water, Environmental Protection Agency, Nov. 2013.
EPA is releasing a Synthesis Report on the Importance of Water to the U.S. Economy. This report is intended to help raise the awareness of water’s importance to our national economic welfare, and to summarize information that public and private decision-makers can use to better manage the nation’s water resources. It highlights EPA’s review of the literature and practice on the importance of water to the U.S. economy, identifies key data gaps, and describes the implication of the study’s findings for future research. EPA hopes this report will be a catalyst for a broader discussion about water’s critical role in the U.S. economy.
Herrick, Charles N. and Joanna L. Pratt, Communication and the Narrative Basis of Sustainability: Observations from the Municipal Water Sector, Sustainability 2013, 5, 4428-4443, Oct. 2013.
Numerous studies attempt to operationalize sustainability and seek to characterize objective, or at least standardized, metrics of sustainable conditions and/or operations. In this paper, we suggest that sustainability is better viewed as an emergent quality, defined in terms of specific institutions and situations. Observations from the water sector suggest that sustainability is not merely a matter of ―bolting on technologies‖, but a complex synthesis of institutional factors, social value perspectives, technologies and engineered artifacts, and natural or environmental conditions.
Although physio-chemical properties, ecological processes and thresholds, and technological factors must inform deliberations, we suggest that the realization of sustainability is at base a narrative enterprise. Observations articulated in this essay were derived through an ensemble research approach including a targeted literature review, a three-phase survey of 18 U.S. water utilities, and a workshop with water sector professionals, regulators, and experts in sustainability and organizational change.
Koundouri, Phoebe and Osiel Gonzalez Davila, The Use of Ecosystem Services Approach in Guiding Water Valuation and Management: Inland and Coastal Waters, Dept. of International and European Economic Studies, Athens University of Economics and Business, Oct. 2013.
In this chapter we develop an interdisciplinary methodology for identifying water-related ecosystem functions into ecosystem services for humans, which are then monetarily evaluated using market and non-market valuation methods. We then apply this methodology to selected case studies on inland and coastal waters and show how these results facilitate the implementation of the EU Water Framework Directive and the EU Marine Strategy Framework Directive.
Pasi, Nidhi and Richard Smardon, Inter-Linking of Rivers: A Solution for Water Crisis in India or a Decision in Doubt, J. of Science Policy and Governance, Vol. 2, Issue 1.
The acute spatial and temporal variations in precipitation patterns have greatly influenced water resources planning, management, and development in India. Specifically, these patterns have led to the development of several water transfer projects in the country. The Inter-Linking of Rivers (ILR) project is a grand example of such a water transfer project. In this paper, we will discuss major justifications and challenges to the implementation of the ILR project and discuss potential alternative policy recommendations for water resources management and planning in India.
Regional water transfer is an attempt to redistribute water from “surplus” to “deficit” zones within India. The ILR project in India envisions linking 37 rivers of 20 major basins in the country through 31 links and canals. The project has been promoted as a solution to the ‘paradox of floods and drought’ in India and will also provide water for irrigation and power generation. However, several issues have been raised and debated on the basis of technical feasibility, environmental, social, ethical, institutional, financial, and political criteria, which question the very rationale, viability and decision-making process of the project. These concerns make it difficult to determine when water transfer can be justified as desirable.
recommendations put forward the need for a fundamental change in thinking and
water resources management in India. The policy recommendations encompass both
and politics of water resources management and planning. The recommendations
present the need
for a bottom-up, participatory, decentralized, and interdisciplinary approach
to water management.
Special emphasis is on understanding demands and justified water needs at the local
level; priority to localized and traditional solutions; efficiency improvements
in agricultural and
irrigation systems; pricing of irrigation water use; education outreach; and an
increased research focus on the different facets of Indian River

U.S. EPA (Environmental Protection Agency). (2013) Watershed modeling to assess the sensitivity of streamflow, nutrient, and sediment loads to potential climate change and urban development in 20 U.S. watersheds. National Center for Environmental Assessment, Washington, DC; EPA/600/R-12/058F. Available from the National Technical Information Service, Alexandria, VA, and online at http://www.epa.gov/ncea.
Watershed modeling was conducted in 20 large, U.S. watersheds to characterize the sensitivity of streamflow, nutrient (nitrogen and phosphorus), and sediment loading to a range of plausible mid-21st century climate change and urban development scenarios. The study also provides an improved understanding of methodological challenges associated with integrating existing tools (e.g., climate models, downscaling approaches, and watershed models) and data sets to address these scientific questions. The study uses a scenario-analysis approach with a consistent set of watershed models and scenarios applied to multiple locations throughout the nation. Study areas were selected to represent a range of geographic, hydrologic, and climatic characteristics. Watershed simulations were conducted using the Soil Water Assessment Tool (SWAT) and Hydrologic Simulation Program―FORTRAN (HSPF) models. Scenarios of future climate change were developed based on statistically and dynamically downscaled climate model simulations representative of the period 2041−2070. Scenarios of urban and residential development for this same period were developed from the EPA’s Integrated Climate and Land Use Scenarios (ICLUS) project. Future changes in agriculture and human use and management of water were not evaluated.
provide an improved understanding of the complex and context-dependent
climate change, land-use change, and water resources in different regions of
the nation. As a
first-order conclusion, results indicate that in many locations future
conditions are likely to be
different from past experience. Results also provide a plausible envelope on
the range of streamflow
and water quality responses to mid-21st century climate change and urban development
in different regions of the nation. In addition, in many study areas the
simulations suggest a
likely direction of change of streamflow and water quality endpoints.
evaluating the implications of different methodological choices help to improve
foundation for conducting climate change impacts assessments, thus building the capacity
of the water management community to understand and respond to climate change. This
information is useful to inform and guide the development of response
strategies for managing
Jaeger, W. K., et al. (2013), Toward a formal definition of water scarcity in natural-human systems, Water Resour. Res., 49,4506–4517, doi:10.1002/wrcr.20249.
Water scarcity may appear to be a simple concept, but it can be difficult to apply to complex natural-human systems. While aggregate scarcity indices are straightforward to compute, they do not adequately represent the spatial and temporal variations in water scarcity that arise from complex systems interactions. The uncertain effects of future climate change on water scarcity add to the need for clarity on the concept of water scarcity.
Starting with a simple but robust definition—the marginal value of a
unit of water we highlight key aspects of water scarcity and illustrate its many
biophysical and socioeconomic determinants. We make four central observations. First,
water scarcity varies greatly across location, time, and a multitude of uses that are valued
either directly or indirectly by society. Second, water scarcity is fundamentally a
normative, anthropocentric concept and, thus, can and should be distinguished from the related,
purely descriptive notion of water deficit. While such an anthropocentric perspective may
seem limiting, it has the potential to encompass the vast range of interests that society has
in water. Third, our ability to understand and anticipate changes in water scarcity requires
distinguishing between the factors that affect the value or benefits of water from
those affecting the costs of transforming water in space, time and form. Finally, this robust and
rigorous definition of water scarcity will facilitate better communication and understanding
for both policymakers and scientists.

This document is explaining our Water Governance Assessment Tool and belongs to the INTERREG IVb DROP project (“Benefit of governance in DROught adaPtation”). First we will explain some background of the project and the tool. In Section 2 we will unfold the general Governance Assessment Tool with its five dimensions and four quality criteria. Section 3 will mention some specific background for governance of drought resilience, that will be incorporated in Section 4 that will specify for each of the five dimensions some specific topics of interest when applying the Tool to issues of drought resilience. Section 5 will stipulate some points of attention when applying the Tool in both data-gathering and –analysis.
The Economic Benefits of Protecting Healthy Watersheds, EPA 841-N-12-004, 2012, on the EPA web site Healthy Watersheds. To find the fact sheet go to the main web site and load the publication number into the search box.
Healthy intact watersheds provide many ecosystem services that are necessary for our social and economic well-being. These services include water filtration and storage, air filtration, carbon storage, nutrient cycling, soil formation, recreation, food and timber. Many of these services have not been monetized and therefore the economic contributions of healthy intact ecosystems are often under-valued when making land use decisions. Ecosystem services provided by healthy watersheds are difficult to replace and most often very expensive to engineer. An engineered ecosystem service replacement may only provide a fraction of the services provided by highly functioning natural systems.
Nelitz, Marc, et al, Tools for Climate Change Vulnerability Assessments for Watersheds, Prepared for Canadian Council of Ministers of the Environment, PN 1494, 2013.
This compendium of tools was prepared for use by technical experts, adaptation planners and resource managers to develop climate change vulnerability assessments of water quantity and water quality at a watershed scale.
Drawing guidance from the Intergovernmental Panel on Climate Change (IPCC) this compendium defines vulnerability assessment as a process for assessing, measuring, and/or characterizing the exposure, sensitivity, and adaptive capacity of watersheds to climate change. The purpose of a vulnerability assessment is to generate knowledge that improves understanding of the implications of climate change. The knowledge generated by a vulnerability assessment can inform allocation of resources for climate change planning and adaptation.
Hill, Margot, Adaptive Capacity of Water Governance: Cases from the Alps and Andes, International Mountain Society, 33(3):248-259. 2013.
The Alps and the Andes are both considered water towers in their respective continents and are thus significant not only for their own water needs but also for those of lowland regions farther downstream. As climate change impacts on the hydrology of mountain regions are increasingly observed, attention is turning to the adaptive capacity of the water governance regimes in mountain communities. This paper explores the adaptive capacity of two contrasting water governance regimes in the Swiss Alps and the Chilean Andes.

Water is essential both to human survival and to the ecosystems on which people depend. Although Maine is blessed with abundant water sources, managing them is crucial for both short and long-term uses. The authors describe the varying time and spatial scales involved in managing water resources, pointing out that policy decisions made at one time can have far-reaching consequences. They provide illustrations of water-resource projects from Maine’s Sustainability Solutions Initiative, ranging in size from Sebago Lake to vernal pools on individual properties.
Murrill, Brandon, Hydraulic Fracturing and the National Environmental Policy Act (NEPA): Selected Issues, Congressional Research Service, 7-5700, R42502, 2012.
This CRS report was prepared for members and committees of Congress. The National Environmental Policy Act (NEPA) requires federal agencies to consider the potential environmental consequences of the actions they propose to take by preparing one of three NEPA documents. Actions that fit within a categorical exclusion (CE) undergo a relatively low level of review because these are actions that an agency has found do not have a significant effect on the environment. A CE may not be used when extraordinary circumstances occur. An environmental assessment (EA) provides a more comprehensive level of review and may be prepared when an agency wishes to determine whether an action requires the preparation of an environmental impact statement (EIS). An EIS is the most comprehensive NEPA document; it requires, among other things, that the agency explain how the proposed action will affect the environment; what unavoidable adverse effects will result; and what alternatives to the proposed action exist. The report covers the approaches used by the USDA Rural Development Agency and the Delaware River Basin Commission.
Jafari, Ashfaque and G. Jagmohan Das, Integrated Conjunctive Use Model, Ins. J. Engg. Res. & Sci. & Tech., Vol. 2, No. 3, Aug. 2013.
Increasing shortages of water supplies coupled with deteriorating quality of the sources has made the earlier paradigms of water resources planning irrelevant. Today's planner needs to adopt a holistic systems approach which considers surface water and ground water as complementary resources paving the way for implementation of conjunctive use concept. In the present study, the conjunctive use model is constructed as an allocation model of surface water and ground water which is constrained by system dynamics comprising of recharge-discharge boundaries of ground water aquifers and inflow-outflow of surface water bodies.
The resulting non-linear programming model is solved by employing Sequential Unconstrained Minimization Technique. Finite element method is employed for solving the governing groundwater flow equation and the resulting hydraulics are incorporated in the optimization model by adopting unit response matrix technique.
The validity of the developed integrated model is demonstrated by applying it to a field problem. The results indicate that the developed mathematical model is robust and capable of simulating the system hydraulics satisfactorily and is responding to the demand variations, cost variations, surface water mass balance and ground water draw down constraints reliably.
Government Accountability Office: Unconventional Oil and Gas Production, Opportunities and Challenges of Oil Shale Development, Testimony Before the Subcommittee on Energy and Environment, Committee on Science, Space, and Technology, House of Representatives, GAO-12-740T, 2012.
Fossil fuels are important to both the global and U.S. economies, and “unconventional” oil and gas resources—resources that cannot be produced, transported, or refined using traditional techniques—are expected to play a larger role in helping the United States meet future energy needs. With rising energy prices one such resource that has received renewed domestic attention in recent years is oil shale.
Oil shale is a sedimentary rock that contains solid organic material that can be converted into an oil-like product when heated. About 72 percent of this oil shale is located within the Green River Formation in Colorado, Utah, and Wyoming and lies beneath federal lands managed by the Department of the Interior’s Bureau of Land Management, making the federal government a key player in its potential development. In addition, the Department of Energy (DOE), advances energy technology, including for oil shale, through its various offices, national laboratories, and arrangements with universities.
Friedrich, Mark Alexander, Hydraulic Fracturing and Energy Security, the Cases of Bulgaria and Poland, Central European University, Budapest, Hungary, 2013.
This thesis seeks to explain how shale gas affects the approaches to energy security taken by Bulgaria and Poland. It claims that the decisions regarding hydraulic fracturing taken by different states have to be seen in the context of the international system, thus through the lens of International Relations theory. This paper argues that Bulgaria and Poland have chosen very different approaches to hydraulic fracturing. However, these approaches are ultimately just a reflection of the two country’s energy policy in general. The cases show the complexity of how to pursue an energy strategy and the multiple factors that influence it. The implication of this finding is that what matters most for achieving energy security is consistency in politics.
Juwana, I., et al, Indicator-Based Water Sustainability Assessment-A Review, Science of the Total Environment, Vol. 438, pp. 357-371, 2012.
In the past few decades, there have been extensive efforts on measuring sustainability. One example is the development of assessment tools based on sustainability indicators. Several individuals and organizations have suggested various indices for assessing sustainability. This paper focuses on the review of water sustainability assessment using the indicator-based approach. It discusses major definitions of sustainable development that have been proposed and more specific concepts of sustainability based on sustainability principles and criteria. It then proceeds with the review of existing definitions, principles and guidelines on sustainable water resource management. The paper then explores elements of indicator-based water sustainability assessment. These elements include the selection of components and indicators, obtaining sub-index values, weighting schemes for components and indicators, aggregation of components and indicators, robustness analysis of the index, and interpretation of the final index value. These six elements are explored considering four existing water sustainability indices and two other sustainability indices that are thought to be useful for the development and use of water sustainability indices.
EPA: Climate Change and Watersheds: Exploring the Links, Science Matters Newsletter, 2013.
EPA water scientists and their partners are studying how climate change may affect watersheds—the network of rivers and streams that feed into larger water bodies such as big rivers, lakes, and oceans. A recent EPA report, referred to as the 20 Watersheds Report, combines climate change models and watershed simulations to develop a better understanding of what changes to streams and rivers we might expect over the next several decades.
Shi, Daniel, et al, America’s Water Risk: Water Stress and Climate Variability, Columbia Water Center, Columbia University, Feb. 2013.
The emerging awareness of the dependence of business on water has resulted in increasing awareness of the concept of “Water Risk” and the diverse ways in which water can pose threats to businesses in certain regions and sectors. Businesses seek to secure sustainable income. To do so, they need to maintain a competitive advantage and brand differentiation. They need secure and stable supply chains. Their exposure risks related to increasing scarcity of water can come in a variety of forms at various points in the supply chain. Given increasing water scarcity and the associated deterioration of the quantity and quality of water sources in many parts of the world, many “tools” have been developed to map water scarcity risk or water risk.
A clear understanding of shortages induced by droughts, in terms of the magnitude, duration and recurrence frequency will better inform the water businesses and water related sectors. To properly diagnose water risk, one needs to examine both existing demand and variations in renewable water supply at an appropriate spatial resolution and unit.
Here, we provide ways to estimate this risk and map it for the USA at a county level. The measures of water risk are estimated using over sixty years of precipitation and the current water use pattern for each county.
EPA: 2012 National Water Program Strategy: Response to Climate Change.
EPA's National Water Program 2012 Strategy: Response to Climate Change sets out long-term goals and specific actions that are EPA's contributions to national efforts to prepare for, and build resilience to, the impacts of a changing climate on water resources. The 2012 Strategy is organized around five long-term programmatic vision areas: protecting water infrastructure; coastal and ocean waters; watersheds; and, water quality. The EPA National Water Program looks forward to working with state, tribal, and local governments, as well as other partners to implement actions that address climate change challenges in these areas.
The 2012 Highlights of Progress report provides a summary of the major climate change-related accomplishments of EPA's national and regional water programs in 2012. This is the fourth climate change progress report for the National Water Program and the first progress report organized around the five long-term programmatic vision areas described in the National Water Program 2012 Strategy: Response to Climate Change.
Padowski, Julie and James Jawitz, Water Availability and Vulnerability of 225 Large Cities in the United States, Water Resources Research, Vol. 48, 2012.
This study presents a quantitative national assessment of urban water availability and vulnerability for 225 U.S. cities with population greater than 100,000. Here, the urban assessments account for not only renewable water flows, but also the extracted, imported, and stored water that urban systems access through constructed infrastructure. These sources represent important hydraulic components of the urban water supply, yet are typically excluded from water scarcity assessments.
Results from this hydraulic-based assessment were compared to those obtained using a more conventional method that estimates scarcity solely based on local renewable flows. The inclusion of hydraulic components increased the mean availability to cities, leading to a significantly lower portion of the total U.S. population considered ‘‘at risk’’ for water scarcity (17%) than that obtained from the runoff method (47%). Water vulnerability was determined based on low-flow conditions, and smaller differences were found for this metric between at-risk populations using the runoff (66%) and hydraulic-based (54%) methods.
The large increase in the susceptible population between the scarcity measures evaluated using the hydraulic method may better reconcile the seeming contradiction in the United States between perceptions of natural water abundance and widespread water scarcity. Additionally, urban vulnerability measures developed here were validated using a media text analysis. Vulnerability assessments that included hydraulic components were found to correlate with the frequency of urban water scarcity reports in the popular press while runoff-based measures showed no significant correlation, suggesting that hydraulic-based assessments provide better context for understanding the nature and severity of urban water scarcity issues.
Becker, Jackson Jae, Microalgae Biofuel Production in the Desert Southwest, 2012.
As evidence of global climate change continues to become more apparent, the world is exploring ways for humans to live sustainable lives on Earth. The combustion of fossil fuels contributes to climate change by introducing greenhouse gases to the atmosphere, and the need for an alternative fuel source is increasingly important. Biofuels from microalgae may provide a fuel source that could meet energy demands while and be less harmful to the environment than fossil fuels. Microalgae production for the use of biofuels provides a renewable, environmentally friendly, and sustainable alternative to fossil fuels. Only requiring light, water, and carbon dioxide, algae has the capability to grow virtually anywhere, however the Southwestern region of the United States would make the most suitable environment for microalgae production. With high amounts of solar radiation, very few cloudy days, and consistent annual temperatures suitable for algae cultivation, the desert Southwest would be the most appropriate area for the production of American energy.
Giupponi, Carlo, Using Modern Decision Support Systems for Evidence Based Policy Making in IWRM in Developing Countries, Universita Ca Foscari di Venezia, Dipartimento di Economia, and Euro-Mediterranean Centre for Climate Change (CMCC).
Decision support systems (DSS) tools in the water management sector are usually developed upon hydrologic simulation models, to which they provide at least an interface for facilitated use beyond the restricted group of model developers. They quite often provide also routines for decision analysis and decision making (e.g., optimization methods). In some cases they also include functionalities targeting the management of participatory processes (e.g., elicitation of stakeholders’ preferences, group decision making, and conflict resolution).
The EU funded SPLASH project (Coordinating European Water Research for Poverty Reduction, http://www.splash-era.net/) has thus included in its activities the writing of this report on Using modern decision support systems for evidence based policy making in IWRM developing countries with a general objective to harness the potential of modern decision support systems for policy making in the field of integrated water resources management in developing countries.
Government Accountability Office, GAO-13-253, Climate Change, Various Adaptation Efforts are Underway at Key Natural Resource Management Agencies, May 2013.
This report examines (1) steps key federal natural resource management agencies—Forest Service, NOAA, Fish and Wildlife Service, National Park Service, and Bureau of Land Management—have taken since 2007 to address adaptation and (2) how these agencies have collaborated at the national level on adaptation since 2007. GAO analyzed the agencies’ climate change adaptation guidance and planning documents and interviewed agency officials. GAO also visited one field location for each agency, selected using a non-probability approach, so the results are not generalizable to all of the agencies’ field locations.
Waylen, Kerry and Julia Martin-Ortega, Report on Knowledge Exchange Workshops on an Ecosystem Services Approach, The James Hutton Institute, Aberdeen, Scotland, UK, 2013.
The WATERS project aims to support the planning processes of decentralized environmental management, in particular to take better account of the pressures caused by future environmental change. To achieve this, VSO volunteers working in 4 districts (Nsjane, Chikhwawa, Salima and Karonga, in Malawi) are working closely with district officials to support their environmental district planning processes and to stimulate the involvement of the local village level committees
In this context, a series of knowledge exchange workshops were organized by The James Hutton Institute in collaboration with LEAD-SEA. The focus of the workshops was an Ecosystem Services Approach (ESAp), using this to promote system thinking in environmental planning and in the involvement of local communities. These workshops initiate a dialogue on how ESAp concepts can usefully inform planning processes for natural resource management and climate change adaptation, supported by the WATERS project. There were three types of knowledge exchange workshops, all held in May 2013:
• Cross-district workshop including high-level officials from the four districts, associated NGO staff and the VSO volunteers.
• District level workshops focused on teams of district officials and other local stakeholders (e.g. NGOs acting locally)
• Village-committee level workshops involving representatives of VNMRCs, other relevant local committees (e.g. health, family planning), extension workers and NGOs
Akhmouch, A. (2012), Water Governance in Latin America and the Caribbean: A Multi-Level Approach, OECD Regional Development Working Papers, 2012/04, OECD
The water debate in relation to poverty alleviation has one dimension that is often sidelined: its relationship with public governance. This report attempts to shed some light on the governance of water policy in Latin American and Caribbean (LAC) countries. It argues that public governance of water in most LAC countries is fragmented, as it is in the OECD area as well, and that greater efforts to co-ordinate water with other policy areas are crucial to maximize the impact on poverty reduction. It emphasizes the need to design water policies in a more integrated manner and implement effective water governance tools and mechanisms that are context-specific, flexible and beneficial to the poor.
Hughes, Sara and Robert Wilkinson, The Role of Governance in Shaping Freshwater Management in America: Toward Integrated Resources Planning, Prepared for the Performance of Environmental Governance Systems: Comparing America and China, Nanjing, China, 2013.
Freshwater is one of the world’s most precious resources, and managing it sustainably is a critically important goal. Fresh water and healthy aquatic ecosystems provide valuable services that society has come to depend on. While many factors determine the outcomes of freshwater management in the U.S., the aim of this paper is to examine the extent to which we can attribute these outcomes to the operation and evolution of governance systems. In this paper, we refer to “governance” as the steering influence of the rules, decision making processes, and incentives provided by both governmental and non-governmental actors, including the private sector and civil society.
In short, while the principles and objectives for freshwater management have changed significantly over the last 100 years, governance has remained a key factor determining freshwater management outcomes in the U.S. Governance systems have helped to distribute authority and incentives in freshwater management; they shape our responses to social and environmental change, and they determine whose voices are heard, and in what decision making venues. In turn, governance systems have created freshwater management challenges and solutions, and they will continue to do so in the future. As society’s goals for freshwater management change, our governance systems may also need to be changed. New challenges and expectations are confronting local, state and national level agencies in the U.S. that are designed to execute basic service functions in a static environment. Governance innovations – such as integrated resources planning and collaborative decision-making – have important potential to address these new challenges.

The articles include such topics as state preemption, regulatory issues, horizontal drilling, water management, clean energy, climate change, the Gulf oil spill, and others.
Implementation of ORD Strategic Research Plans: A Joint Report of the Science Advisory Board and ORD Board of Scientific Counselors, EPA-SAB-12-012, 2012.
This report was submitted to the Administrator of the Environmental Protection Agency, as a blueprint for future actions within the Office of Research and Development (ORD). It covers all aspects of ORD, not just water resources concerns. Some important highlights of the report are:
• The Air, Climate and Energy program should include a plan for energy research and indicate how this research will integrate with the plans for climate and air quality research.
• The Chemical Safety for Sustainability program should demonstrate how its research products impact upon end users (e.g., risk managers, policy makers) and how it brings value for informing decisions.
• The Safe and Sustainable Waters program should identify and seek opportunities for leveraging research of other federal agencies and engage with communities in setting the program’s research priorities and research development. Program linkages with sustainability, nutrient management and green infrastructure are critical to the success of this program.
• ORD should develop and implement a strategic vision for the Human Health Risk Assessment program to enhance linkages among the program’s four thematic areas and other research programs, particularly the Chemical Safety for Sustainability program.
• The Homeland Security Research Program, a valuable national resource, should evaluate its potential contributions to sustainability and consider adopting a broader mission that considers the multiple benefits of its products and application of its research to help respond to a wide variety of environmental disasters.
• The Sustainable and Health Communities program should focus its science questions and research more clearly; articulate how it will interact with local communities, state environmental agencies and regional offices; and clearly distinguish research from implementation of environmental programs.

Benson, Reed D., Federal Water Law and the “Double Whammy”; How the Bureau of Reclamation Can Help the West Adapt to Drought and Climate Change, University of New Mexico School of Law, 2011.
The water resources of the American West—especially the Southwest—are at risk from climate change, as an already arid region grows even drier, warmer, and prone to drought. The dual threat of drought and climate change is a particular challenge for the U.S. Bureau of Reclamation (USBR), which operates hundreds of federal water projects throughout the region. USBR has some authority to deal with these problems under the 2009 SECURE Water Act (for climate change) and the 1992 Drought Relief Act (for drought). This article considers USBR’s climate change and drought programs, examining both the authorities and the implementation. It concludes with recommendations on how USBR could better use the Drought Relief Act to help reduce the impacts of future water shortages.
Veljkocic, Nebojsa D., Sustainable Development Indicators: Case Study for South Morava River Basin, Serbian Environmental Protection Agency, Ministry of Environment, Mining and Spatial Planning, Republic of Serbia, 2013.
The subject of this research study is the elaboration and evaluation of indicators of sustainable development in the field of river basin management. The aggregate indicator entitled Ecoregion Sustainable Development Index is identified by calculation of an average value by the procedure of leveling of proportion changes of three key indicators (demographic emission index, water quality index, and industrial production index). The developed aggregate indicator of sustainable development is calculated and analyzed for South Morava river basin in Serbia, for the period from 1980 to 2010. The beneficiaries of these indicators are the experts from the field of environmental protection and water management, who should use it for elaboration of reports directed towards the creators of economic development policies and river basin management planning. Elaborated according to the given methodology, the indicator Ecoregion Sustainable Development Index is available for the decision makers on the national level, internationally comparative and it provides the conditions for further elaboration and application.
Breen, Sarah-Patricia and Sarah Minnes, Water and Watershed Management: A Regional Development Perspective, Canadian Regional Development: A Critical Review of Theory, Practice, and Potentials, Social Sciences and Humanities Research Council of Canada, March 2013.
This paper focuses on water and watershed management and its links with regional development. A watershed can be defined as a unique area of land serving as a natural management unit which captures precipitation, filters and stores water, and regulates its release. Watersheds are defined by complex relationships between human and natural processes, encompassing the interaction between soil, vegetation, animals, people, water, and climate. The study of watershed management includes all relevant characteristics, often with the overall goal of sustainable distribution of water and other watershed resources.
Book Review: Maxwell, Steve, The Future of Water: A Startling Look Ahead, American Water Works Association, and Zetland, David, The End of Abundance: Economic Solutions to Water Scarcity, Aguanomics Press. Both reviewed by G. Tracy Mehan III. Environmental Forum, May/June 2012.
Shifts in migratory patterns, driven by water shortages and escalating costs, are some of the transformations outlined in Steve Maxwell’s very readable new book, The Future of Water: A Startling Look Ahead, written with Scott Yates. It surveys the United States and the globe to assess trends and potential solutions to what he does not hesitate to call “an inexorable planetary crisis.” A growing population, poverty, government water and energy subsidies, failure to price the resource, overconsumption, and an overall failure of political will and governance have contributed to this crisis.
Applying the lessons of economics and incentives to water management is the aim of Dr. David Zetland in his fine new volume, The End of Abundance: Economic Solutions to Water Scarcity. He believes the water sector can encourage better stewardship and a greater degree of social harmony by substituting pricing and market allocation of limited water supplies for political management.
N.C. Dey, et al, Assessing Environmental and Health Impact of Drought in the Northwest Bangladesh, J. Environmental Science and Natural Resources, 4(2): 89-97, 2011.
Drought, the result of regional climatic variability is one of the dominant threats to environment. This study focuses on the biophysical, environmental and health issues concerning drought occurrence in northwest region of Bangladesh. Using both primary and secondary data, the analysis revealed that, during the drought period, rainfall as the dominant factor of supplying surface water and normalizing the dryness of the nature was almost 46% lower than the previous (normal) years. Similarly, average monthly sunshine hours in the drought year was about 7% higher compared to that of the normal year. On an average, groundwater level declined more than one meter compared to the previous years. Thus, many of the tubewells turned dry or failed to supply the required quantity of water for household and irrigation purposes. A significant number of surface water bodies including ponds, ditches, canals and streams had little volume of low quality water. In normal years, cent percent households used hand tubewells (HTWs) as the major source of drinking water, while in the drought period only 90% households could use HTW water since substantial proportion of the HTWs turned dry. People had to collect drinking and domestic water from far distance to meet the basic requirements. Increase in temperature and prevalence of severe dust during drought periods compared to the normal years caused different health hazards including dysentery and diarrhea due to unsafe drinking water.

Global Water Partnership, (GWP), established in 1996, is an international network open to all organizations involved in water resources management: developed and developing country government institutions, agencies of the United Nations, bi- and multilateral development banks, professional associations, research institutions, non-governmental organizations, and the private sector. GWP was created to foster Integrated Water Resources Management (IWRM), which aims to ensure the coordinated development and management of water, land, and related resources by maximizing economic and social welfare without compromising the sustainability of vital environmental systems.
GWP promotes IWRM by creating fora at global, regional, and national levels, designed to support stakeholders in the practical implementation of IWRM. The Partnership’s governance includes the Technical Committee (TEC), a group of internationally recognized professionals and scientists skilled in the different aspects of water management. This committee, whose members come from different regions of the world, provides technical support and advice to the other governance arms and to the Partnership as a whole. The Technical Committee has been charged with developing an analytical framework of the water sector and proposing actions that will promote sustainable water resources management. The Technical Committee maintains an open channel with the GWP Regional Water Partnerships (RWPs) around the world to facilitate application of IWRM regionally and nationally.
Worldwide adoption and application of IWRM requires changing the way business is conducted by the international water resources community, particularly the way investments are made. To effect changes of this nature and scope, new ways to address the global, regional, and conceptual aspects and agendas of implementing actions are required.
Seungho Lee, Comparative Research on River Basin Management in Korea and Japan, Korea University, Seoul, 2011.
This research aims to explore the mode of River Basin Management (RBM) in Korea and Japan with a comparative perspective. The efforts of implementation of RBM in Korea have included the several attempts to enact the Basic Water Bill, and river basin environmental offices and committees in the four major rivers. Japan has also endeavored to introduce policy efforts to accommodate the new approach including the establishment of river basin comprehensive water resources management committees. Despite such policy efforts, the comparative analyses indicate a series of challenges. The first challenge is to transfer the relevant power from center to river basins. Second, there is a lack of laws and regulations to support a set-up of RBM. Third, river basin organizations are not compatible with the current administrative systems in Korea and Japan. Fourth, river basin organizations require independent funding. Fifth, there are conflicts between ministries involved in water management. It is concluded that more emphasis should be placed on establishment of adequate institutions and legal settings in order to establish RBM in these countries alongside political commitment.
Summary of the High-Level Meeting of the Global Thematic Consultation on Water in the Post-2015 Development Agenda, The Hague, the Netherlands, March 21-22, 2013.
The High-Level Meeting of the Global Thematic Consultation on Water in the Post-2015 Development Agenda took place from 21-22 March 2013, in The Hague, the Netherlands. The meeting consisted of the Multi-Stakeholder Dialogue on Water in the Post-2015 Development Agenda, also called “Wings for Water,” which took place on 21 March, and the celebration of International World Water Day on the theme of water cooperation, which took place on 22 March. The meetings, hosted by the Netherlands, brought together representatives of governments, international organizations, civil society, religious bodies, the private sector and youth, to discuss the outcomes of the Global Thematic Consultation on Water in the Post-2015 Development Agenda and the Dutch “Wings for Water” Initiative outcome, the “Wake Up Call on Water.” The high-level segment took place on the afternoon of 22 March with the convening of the High-Level Forum on the Global Thematic Consultation on Water in the Post-2015 Development Agenda, which endorsed the outcomes of the Global Thematic Consultation.
Sustainability and the U.S. EPA, National Research Council, National Academies Press, 2013.
An ad hoc committee under the NRC has authored a consensus report, released in August 2011, for the U.S. Environmental Protection Agency (EPA)'s Office of Research and Development (ORD) to help define their efforts to incorporate sustainability concepts into agency programs. This report builds on existing sustainability efforts that ORD has conducted by strengthening the analytic and scientific basis for sustainability as it applies to human health and environmental protection within the Agency's decision-making process. Dissemination activities are being planned for 2013. The report covers many more topics in addition to water resources.
Journal of Contemporary Water Research and Education, Issue 147, Scale Interactions, Universities Council on Water Resources, Southern Illinois University, Carbondale, Illinois, March 2012.
The challenge is to articulate the conditions under which scale imposed constraints are systematic and to develop models that compensate or standardize scale-based variation. Following this point of view, different model structures would be needed to accurately represent the phenomenon at different scales. For instance, studies of water demands at the national or sub-national scale would need lesser bundles of attributes to define the problem than studies at the local scale – wherein many more factors interact and become important (distance to water source, number of households having access, duration, timing etc.). Primary issues therefore center on gaining a better understanding of how to effectively measure and characterize scale; how to use scale information in judging the fitness of data for a particular use; how to automate scale change or scaling and simultaneously represent data at multiple scales; and how scale and change in scale affect information content, analysis, and conclusions about patterns and processes in water resources, hydrology, and climate. The papers in this issue address these concerns.
Government Accountability Office, Oil and Gas, Interior Has Strengthened Its Oversight of Subsea Well Containment, but Should Improve Its Documentation, GAO-12-244, February 2012.
On April 20, 2010, an explosion and fire on board the Deepwater Horizon, an offshore drilling rig, resulted in 11 deaths and the largest oil spill in U.S. history in the Gulf of Mexico. After this event, the Department of the Interior (Interior), which oversees oil and gas operations in federal waters, suspended certain offshore drilling operations. After developing new guidance, Interior resumed approving drilling operations in the Gulf of Mexico. GAO was asked to examine (1) the industry’s improved capabilities for containing subsea wells (those on the ocean floor) in the Gulf of Mexico; (2) Interior’s oversight of subsea well containment in the Gulf of Mexico; and (3) the potential to use similar subsea well containment capabilities in other federal waters, such as those along the Alaskan coast. This report documents the results of this investigation.
Ford, Rachel N., Managing Great Lakes Water as a Common Pool Resource: Barriers to and Opportunities for Collective Action Among Irrigators in Southwest Michigan, Michigan State University, 2012.
In response to the Great Lakes-St. Lawrence River Basin Water Resources Compact, which protects the region against diversions of water outside of the Great Lakes- St. Lawrence River Basin, the State of Michigan has created a water use program to be implemented by the Michigan Department of Environmental Quality (DEQ). The program regulates large-quantity water withdrawals (LQWs) of greater than 100,000 gallons per day to prevent adverse resource impacts (ARIs), defined as reduction of the index flow in streams and subsequent decline of fish populations. The rivers and their corresponding watersheds in the state were segmented into over 5,000 catchment areas to be used as management units for the identification and mitigation of ARIs. An assessment process consisting of an online screening tool and a site-specific review uses data on aquifer yields, stream index flow, and fish population response to categorize each new or increased LQW according to the risk of ARI. Should an ARI be detected in a catchment, all registered and permitted large-quantity water appropriators potentially will be convened into a water user committee to create a management plan for reducing water use in the area. The dynamics of these negotiations are unknown. This research explores a case study of agricultural irrigators in Southwest Michigan for conditions that influence transaction costs of negotiating and monitoring rules of a water reduction management plan. The identification of these potential barriers and opportunities for collective action results in suggestions for the DEQ to reduce transaction costs and improve the efficacy of the water use program in Michigan.
Kumar, M. Dinesh, et al, Capacity Building in Water Resource Sector of India, Institute for Resource Analysis and Policy, Hyderabad, 2012.
http://irapindia.org/Capacity%20Building.pdf (You may have to paste this link in your browser for it to work properly)
With mounting water scarcity, the priorities for the water agencies of the country have broadened from mere water development to encompass water allocation and water resources management. But, the institutional capacity building of the agencies responsible for water resources and services management hasn’t kept pace with the changing times. Building institutional capacity warrants primarily the following: i] framing the right kind of water policies; ii] crafting the right kind of rules and regulations, institutions and instruments; and, iii] fostering the needed organizational changes among the agencies concerned for water allocation and sustainable water resources management.
The paper highlights three sets of key issues facing them. They are: a] team building of professionals with multi-disciplinary skills, to provide research and expert inputs for policy formulation, institutional design and design of economic instruments; and, b] mobilizing resources and skills for creating new organizations including development of local institutions, and restructuring wherever needed; and, c] augmenting the overall strength of technical staff in various departments engaged in water resources management and water-related services. Availability of multitude of professional agencies which can undertake tailor-made capacity building activities for various stakeholders is a critical issue. The paper argues that focus of the state and central governments should now be on building world-class human resource base, with trainers, researchers and water management professionals with multi disciplinary skills.
Sarukkalige, Ranjan, et al, Evaluation of the Impacts of Land Use on Storm Water Quality: Case Study from Western Australia, International Journal of Environmental Science and Development, Vol. 3, No. 1, Feb. 2012.
This study evaluates the impacts of land use on storm water quality. Storm water samples were collected from three main land use areas; residential, commercial and industrial lands around the Town of Victoria Park in Western Australia. Each sample was tested to measure important water quality parameters. Time variation of storm water flow, rainfall intensity and storm water quality clearly showed that the highest concentration of pollutants in storm water occurs during the first flush event. Further analysis shows that the commercial storm water demonstrated the cleanest appearing storm water with lowest amounts of suspended solids whereas the industrial storm water had the dirtiest appearing storm water quality. Nutrients in the residential storm water have the lowest nitrate, ammonia and phosphate concentrations. Overall, the industrial land use site recorded the worst storm water quality. Study further provides recommendations for water quality improvement and management controls.
K. Shreelakshmi et al, Situation Analysis on Climate Change, Ecosystems for Life: A Bangladesh-India Initiative, International Union for Conservation of Nature, 2012.
Bangladesh and India share three major river systems: the Ganga, the Brahmaputra and the Meghna. Along with their tributaries, these rivers drain about 1.75 million sq km of land, with an average runoff of 1,200 cu km. The GBM system also supports over 620 million people. Thus, the need for cooperation on trans-boundary waters is crucial to the future well-being of these millions.
Ecosystems for Life will develop, through dialogue and research, longer-term relationships between various stakeholder groups within and between the countries. It will develop a common understanding to generate policy options on how to develop and manage natural resources sustainably such that livelihoods and water and food security improve. Inter-disciplinary research studies will be conducted by bringing together experts from various fields from both countries so that relevant issues are holistically grasped.
The initiative centers around five broad thematic areas:
• food security, water productivity and poverty;
• impacts of climate change;
• inland navigation;
environmental security; and
• biodiversity conservation.
Hezri, Adnan and Rospidah Ghazali, A Fair Green Economy?, Studies of Agriculture, Energy and Waste Initiatives in Malaysia, United Nations Research Institute for Social Development, December 2011.
Malaysia’s national green economy framework reflects a mainstream economics framing, such as that of the United Nations Environment Program (UNEP) and the Organization for Economic Co-operation and Development (OECD). That is, it attempts to strengthen the economy via incentives, the tax system, pricing, regulatory frameworks and prioritized investments. Its target group, however, is industries located in urban centers and not the poor communities living in the rural areas of Malaysia. Consequently, the social dimension is not clearly spelled out in terms of program and policy tools, despite the fact that “improving the quality of life for all” is one of the four pillars of Malaysia’s National Green Technology Policy. This is manifested in the country’s green policy design, evincing an urban bias. Given this scenario, the empirical section of this paper surveys piecemeal greening projects in a subnational context, particularly in Malaysia’s rural frontier where poverty is still a major challenge. These projects are not officially considered a part of the country’s recent response to the green economy agenda. Through case studies of agriculture, renewable energy and waste-to-wealth initiatives, the paper illustrates that green economy in Malaysia has most potential when it arises from the engagement of communities. The paper explores the contribution of these three sectors in meeting social policy objectives, as well as the challenges. Specifically, the paper investigates the benefits from a greener economy that will accrue to society members who are disadvantaged economically and geographically.
Ajeagah, Gideon, et al, Bacteriological and Environmental Characterization of the Water Quality in the Danube River Basin in the Galati Area of Romania, African Journal of Microbiology Research, Vol. 6(2), 16 January 2012.
http://www.academicjournals.org/AJMR Click on Archive, then click on issue of 16 January 2012, Vol. 6(2). The paper is further down the list of authors.
In order to contribute with date to the Danube River Basin which is a prime European waterway, this analysis was carried out on the one hand to investigate the possibilities of sanitary risks that are incurred by the riverside population as they are engaged in professional recreational activities that impose a direct contact between man and water, that is intensely developed along the aquatic system and on the other hand to indicate a clear cut picture of the final level of coliforms and Escherichia coli that is actually present in the Galati industrial segment of the Danube River. Total coliforms, faecal coliforms and E. coli could attain values reaching 1.5×103, 9.5×102 and 6.4×103 CFU/ml, respectively for the aquatic ecosystems analysed. A variation of these parameters with respect to the ecodynamical characteristic of the Danube water quality such as temperature, pH, total dissolved solids, salinity and hydrogen sulphite reveal the preponderant role that abiotic factors play in the dispersion of bio-contaminants in a broad basin ecosystem. While the persistence of E. coli during the sampling period from June to September confirm the fact that there is a continuous faecal pollution of this medium. The high presence of organic pollutants in this medium, combined with the presence of coliforms and E. coli, could be related to an accumulation of waste matter all along the ecosystem, also due to the lack of wastewater treatment plants for domestic and industrial discharges, the high impact of human activities across the international river basin and the difficulties encountered in the natural operational processes of self purification.
Wan-Jiun Chen and Shyue-Cherng Liaw, Evaluation of Economic Values for Watershed Management in Northeastern Taiwan, Chinese Culture University and National Taiwan Normal University, Taiwan.
A watershed can generate benefits for residents for providing multiple services. However, the quest for services from a watershed and the consequent benefits are not identical for different groups of people. This paper took upstream Lanyang watershed (ULW) in Taiwan for a case study to investigate the opinions from different related groups of people and to assess the economic values generated from this upstream watershed for them. The Lanyang watershed is located in northeastern Taiwan. Two groups of related people are under investigation. One is the local residents of this upstream watershed, and the other is the downstream residents. Consistent with the behavior of rent-seekers, divergent interests arouse their opinions toward watershed management. Both groups of people concern about land and water conservation to ensure the safety of their lives and property. In addition, upstream residents devote much attention to local economic development. The economic value of ULW is higher for local ULW residents, with comparison of the downstream residents. Initiating eco-tourism and transforming agriculture for recreation purpose in this upstream watershed can create jobs, increase local income without further destructive exploitation. These are suggested as feasible and sustainable development practices for effectively integrating multiple but divergent needs from different groups of people. Public involvement management can support the success of sustainable development of this watershed.
EPA Hydraulic Fracturing Study, Summary of Technical Roundtables
On November 14–16, 2012, the U.S. Environmental Protection Agency (EPA) conducted a series of five technical roundtables focused on each stage of the water cycle, as defined in the study plan for EPA’s Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources. In this study, each stage of the cycle is associated with a primary research question:
• Water acquisition: What are the possible impacts of large volume water withdrawals from ground and surface waters on drinking water resources?
• Chemical mixing: What are the possible impacts of hydraulic fracturing fluid surface spills on or near well pads on drinking water resources?
• Well injection: What are the possible impacts of the injection and fracturing process on drinking water resources?
• Flowback and produced water: What are the possible impacts of flowback and produced water (collectively referred to as “hydraulic fracturing wastewater”) surface spills on or near well pads on drinking water resources?
• Wastewater treatment and waste disposal: What are the possible impacts of inadequate treatment of hydraulic fracturing wastewater on drinking water resources?
Based on feedback from the November 2012 roundtables, EPA will host in-depth technical workshops to address specific topics in greater detail. EPA believes a transparent, research-driven approach with significant stakeholder involvement can address questions about hydraulic fracturing.
Knapen, M.J.R., et al, Evaluating and Improving OpenMI as a Model Integration Platform Across Disciplines, 19th International Congress on Modeling and Simulation, Perth, Australia, December 2011.
OpenMI is a open source software standard for dynamically linking models at runtime, which can potentially be used in many domains, but is currently mainly applied in the water and environmental domains. This paper examines the use of OpenMI in several multi-disciplinary large projects that worked on integrated models. These projects operated in the disciplines of agriculture, land use, nitrogen cycling, forestry, hydrology and economics. The overall objective is to investigate the strengths and weaknesses of integrated modelling according to open frameworks based on standards in general, and OpenMI in particular, based on feedback from both software developers and modelers that contributed to the aforementioned projects on the use of OpenMI, combined with the authors’ knowledge and experience. Recommendations for improvements of OpenMI specific and integrated modelling in general are presented.
The OpenMI (http://www.openmi.org/ ) is a data and model integration framework, designed to take independent data and computing systems and provide a standard means of describing how time series are communicated between the systems. It has been developed from the need to answer integrated hydrological catchments management questions within the EU 5th framework program project. The OpenMI is available under the terms of the open source license LGPL (SDK implementations might apply the even less restrictive MIT open source license) with the aim of easier dissemination.
The OpenMI is under development and under the supervision of the OpenMI Association, which has as its main objectives to promote its development, use, management and maintenance. It is an entirely open international group of organizations and people, with a small core team that supports, responds to and is guided by a growing active worldwide user community.
EPA-SAB-12-012: In September 2012 the EPA Science Advisory Board sent their recommendations to the EPA Administrator. This report covers all aspects of the Office of Research and Development, and goes far beyond water resources. The report can be found at:
The Science Advisory Board (SAB) and the Executive Committee of Office of Research and Development (ORD’s) Board of Scientific Counselors (BOSC) have strongly supported the consolidation of EPA’s research programs as part of an integrated transdisciplinary approach to research that aligns with your priorities and takes a systems approach to sustainability. Over the past year, the ORD has realigned its research into six new program areas: Air, Climate and Energy; Safe and Sustainable Water Resources; Sustainable and Healthy Communities; Chemical Safety for Sustainability; Human Health Risk Assessment; and Homeland Security Research. ORD requested that the SAB and the BOSC provide advice on implementation of these new program areas. The SAB and the BOSC agree that ORD has made remarkable progress towards integrated transdisciplinary research, systems approaches and sustainability despite changes in leadership over the past year. The Strategic Research Action Plans developed by ORD for its six research programs are important achievements. These plans crystallize and communicate ORD’s new approach to its mission.
The report provides recommendations to strengthen each research program. Some highlights are listed below:
· The Air, Climate and Energy program should include a plan for energy research and indicate how this research will integrate with the plans for climate and air quality research.
· The Chemical Safety for Sustainability program should demonstrate how its research products impact upon end users (e.g., risk managers, policy makers) and how it brings value for informing decisions.
· The Safe and Sustainable Waters program should identify and seek opportunities for leveraging research of other federal agencies and engage with communities in setting the program’s research priorities and research development. Program linkages with sustainability, nutrient management and green infrastructure are critical to the success of this program.
· ORD should develop and implement a strategic vision for the Human Health Risk Assessment program to enhance linkages among the program’s four thematic areas and other research programs, particularly the Chemical Safety for Sustainability program.
· The Homeland Security Research Program, a valuable national resource, should evaluate its potential contributions to sustainability and consider adopting a broader mission that considers the multiple benefits of its products and application of its research to help respond to a wide variety of environmental disasters.
· The Sustainable and Health Communities program should focus its science questions and research more clearly; articulate how it will interact with local communities, state environmental agencies and regional offices; and clearly distinguish research from implementation of environmental programs.
EPA Healthy Watersheds Initiative, Government web site, 2012.
EPA has launched an initiative called “Healthy Watersheds” that emphasizes protection and conservation of aquatic ecosystems. The initiative is being introduced on a Web site which provides information on tools to identify and protect healthy watersheds and their components. The Web site provides critical information for making strategic decisions to both protect and restore our nation’s waters. State officials will benefit greatly from the Healthy Watersheds initiative since they generally operate at the scale needed to implement strategic conservation decisions and are well-suited for assessing and managing watershed resources. Local governments, watershed practitioners, and regional agencies will also benefit from this initiative.
Symmonds, Graham and Trevor Hill, Smarter Water: Ensuring Water Sustainability Via Infrastructure, Incentives, and Information, Global Water Resources, Phoenix, Arizona, 2011.
All nations are now recognizing that the world’s water is a finite resource subject to increased variability in both availability and quality by climate change and population growth. To survive in this new reality, water managers must not only increase the availability of conservation infrastructure – dual water mains etc – they must also increase the availability of information available to consumers and provide direct incentives for conservation.
Addressing this water crisis requires a fundamental change in planning and infrastructure deployment employed for water resources; a change from the largesse policies of the past to stewardship of the future and a commitment to engage the consumer in active conservation. By combining the new water delivery paradigm emphasizing the “right water for the right use” with a concerted rate incentive program and data rich information for consumer, significant operational and infrastructure efficiencies are achieved while promoting water conservation at the user level.
Shu-Quing Yang, et al, Novel Separation, Protection, and Prevention (SPP) Water Management Strategy and Its Applications, School of Civil, Mining, & Environmental Engineering, University of Wollongong, New South Wales, Australia, 2011.
Clean freshwater is the most precious resource in the world and the development of water resources has had a very long history, as early as humans changed from being hunters and food collectors to modern civilization. At very early stage, people had to rely on creeks, rivers and lakes for their water demand that was relatively small, and today humans have accumulated the knowledge and techniques for water storage, building artificial lakes or reservoirs to meet their huge water demand due to industrialization and urbanization. The world’s earliest large dam was the Sadd-el-kafara Dam built in Egypt between 2950 and 2690 B.C. Up to now, water from lakes and reservoirs is still the main source for people’s water supply. However these large water bodies suffer two problems incurred by nature and human being, one is sedimentation and the other water pollution. Two of them jointly reduce the available amount of clean water and deteriorate the water quality. Consequently, approximate 1.1 billion people lack of safe drinking water and between 2 and 5 million people die annually from water-related disease. It is understandable that with the population growth in the world, it is difficult to provide sufficient clean water to meet the demand; on the other hand, our natural systems are under pressure from drought (too little), floods (too much), pollution (too dirty), climate change, and other stresses. This creates serious challenges for water management. Within a generation, water demand in many countries is forecast to exceed supply by an estimated 40%. In other parts of the world prone to flooding, catastrophic floods normally expected once a century could occur every 20 years instead.
Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources, EPA 601/R-12/011, Dec. 2012. http://www.epa.gov/hfstudy/pdfs/hf-report20121214.pdf
Movahedi, Reza and Hadi Fathi, Analysis of Sustainable Water Resource Management in Agriculture: Case of Kurdistan, Iran, International Journal of Agriculture: Research and Review, Vol. 2 (2), 53-58, 2012.
The purpose of this research was to analyze the supportive policies and dimensions of sustainable water resources management (SWRM) in agriculture of Kurdistan Province in Iran. The research method was quantitative research. Total population of experts in the study included all agricultural extension experts (n= 135) of agricultural organizations of Kurdistan Province, Iran. Based on frequency of respondents about important rate of supportive policies regarding SWRM in agriculture, 76.3% of respondents stated that encouraging farmers to use sustainable methods had very high importance. In reference to the frequency of respondents about extension system roles on realization of SWRM dimensions in agriculture, 71.2% of respondents stated that increasing knowledge of farmers regarding SWRM had very high importance for supporting SWRM in agriculture.
Kilic, Murat and Suer Anac, Sustainable Management of Large Scale Irrigation Systems: A Decision Support Model for Gediz Basin, Turkey, Ege University, Department of Irrigation and Agricultural Structures, Izmir, Turkey.
While water on a global scale is plentiful, 97% of it is saline and 2.25% is trapped in glaciers and ice, leaving only 0.75% available in freshwater aquifers, rivers and lakes. About 70% of this fresh water is used for agricultural production, 22% for industrial purposes and 8% for domestic purposes. Increasing competition for water for domestic and industrial purposes is likely to reduce the water available for agriculture.
In developing countries, agriculture continues to be an important economic sector as it makes a significant contribution to national incomes and economic growth. As water scarcity intensifies in many regions of the world, better management of irrigation is becoming an issue of paramount importance. Generally, optimal multi-cropping patterns and irrigation areas associated with appropriate reservoir operation and irrigation scheduling are essential for increasing the overall efficiency of reservoir-irrigation systems.
In this investigation, the real-time irrigation programming model MONES 4.1 developed by Kilic was applied to the irrigation system known as Sector VII which is served by 28 tertiary canals in the Right Bank Irrigation System of Ahmetli Regulator in the Lower Gediz Basin, Turkey. Irrigation programs from the model for different periods were analyzed, and the results were compared with the actual irrigation applications in the system.
Hamdan, Sami, Artificial Recharge of Groundwater with Stormwater as a New Water Resource: Case Study of the Gaza Strip, Palestine, Institut fur Angewandte Geowissenshaften, Technische Universitat Berlin, 2012.
Due to the existing deficit in the water resources budget in the Gaza Strip, the groundwater quality was deteriorated and salinity reached more than 1500 mg/l as chloride ion. Moreover the groundwater level declined continuously until it reached few meters below sea levels in most areas. The average annual rainfall amounts to 350 mm giving a bulk volume of rainfall fallen on the Gaza Strip amounting to 114 Mm3 every year, from which only 45 Mm3/year is infiltrated naturally to groundwater, and the rest either evaporates or flows to the sea.
Non-conventional water resources such as desalination, wastewater reuse and storm water harvesting are needed to bridge the gap in water resources budget. Desalination is faced by financial constraints in addition to problems of available power. Urban stormwater harvesting became an important water resource that plays a significant role in enhancement of water resources management. It has a potential input of about 28 Mm3 per year as runoff, from which 22 Mm3 come from urban areas in cities only based on the existing land use.
Most of the scarce water countries promote rainwater harvesting system (RWH) as one of the strategic water resources due to growing demand of water. RWH is practiced commonly in remote areas especially in the villages, where connecting water pipes is not economically feasible. Qualitatively, the harvested rooftop storm water runoff in Gaza has proved to be suitable for artificial recharge and close to WHO drinking water standards, where low concentrations of chloride and nitrate were found. The measured concentrations of lead, cadmium, iron, zinc, chromium, aluminum and copper were in the acceptable limits set by WHO for drinking purposes.
Oil and Gas: Information on Shale Resources, Development, and Environmental and Public Health Risks, Government Accountability Office, GAO-12-732, Sept. 2012.
Estimates of the size of shale oil and gas resources in the United States by the Energy Information Administration (EIA), U.S. Geological Survey (USGS), and the Potential Gas Committee––three organizations that estimate the size of these resources—have increased over the last 5 years, which could mean an increase in the nation’s energy portfolio. For example, in 2012, EIA estimated that the amount of technically recoverable shale gas in the United States was 482 trillion cubic feet—an increase of 280 percent from EIA’s 2008 estimate. However, according to EIA and USGS officials, estimates of the size of shale oil and gas resources in the United States are highly dependent on the data, methodologies, model structures, and assumptions used to develop them. In addition, less isknown about the amount of technically recoverable shale oil than shale gas, in part because large-scale production of shale oil has been under way for only the past few years. Estimates are based on data available at a given point in time and will change as additional information becomes available. In addition, domestic shale oil and gas production has experienced substantial growth; shale oil production increased more than fivefold from 2007 to 2011, and shale gas production increased more than fourfold from 2007 to 2011.
Oil and gas development, whether conventional or shale oil and gas, pose inherent environmental and public health risks, but the extent of these risks associated with shale oil and gas development is unknown, in part, because the studies GAO reviewed do not generally take into account the potential long-term, cumulative effects. For example, according to a number of studies and publications GAO reviewed, shale oil and gas development poses risks to air quality, generally as the result of (1) engine exhaust from increased truck traffic, (2) emissions from diesel-powered pumps used to power equipment, (3) gas that is flared (burned) or vented (released directly into the atmosphere) for operational reasons, and (4) unintentional emissions of pollutants from faulty equipment or impoundments—temporary storage areas.
Similarly, a number of studies and publications GAO reviewed indicate that shale oil and gas development poses risks to water quality from contamination of surface water and groundwater as a result of erosion from ground disturbances, spills and releases of chemicals and other fluids, or underground migration of gases and chemicals. For example, tanks storing toxic chemicals or hoses and pipes used to convey wastes to the tanks could leak, or impoundments containing wastes could overflow as a result of extensive rainfall. According to the New York Department of Environmental Conservation’s 2011 Supplemental Generic Environmental Impact Statement, spilled, leaked, or released chemicals or wastes could flow to a surface water body or infiltrate the ground, reaching and contaminating subsurface soils and aquifers.
addition, shale oil and gas development poses a risk to land resources and
wildlife habitat as a result of constructing, operating, and maintaining the
infrastructure necessary to develop oil and gas; using toxic chemicals; and
injecting fluids underground. However, the extent of these risks is unknown.
For example, the studies and publications GAO reviewed on air quality
conditions provide information for a specific site at a specific time but do
not provide the information needed to determine the overall cumulative effects
that shale oil and gas activities may have on air quality. Further, the extent
and severity of environmental and public health risks identified in the studies
and publications GAO reviewed may vary significantly across shale basins and
also within basins because of location- and process-specific factors, including
the location and rate of development; geological characteristics, such as
permeability, thickness, and porosity of the formations; climatic conditions; business
practices; and regulatory and enforcement activities.
Note: Hydraulic fracturing is now the subject of an extensive study being carried out by the U.S. Environmental Protection Agency. See http://www.epa.gov/hfstudy/ The EPA plan for the study is also located on this site.
Sustainable Development of Algal Biofuels in the United States, Board on Energy and Environmental Systems, National Research Council, National Academies Press, Washington, 2012.
production of renewable fuels, including algal biofuels, has the potential to meet the
dual goals of improving energy security and decreasing greenhouse-gas (GHG) emissions
from the transportation sector in the United States. Biofuels produced from
cyanobacteria1 offer potential advantages over terrestrial plant-based
biofuels, such as high biomass
productivity and the ability to grow in cultivation ponds or photobioreactors
on nonarable lands using saline water or wastewater sources. However, along
with potential environmental
and social benefits, production of algal biofuels could result in significant resource
inputs and in negative environmental and other detrimental effects, as is true
of all forms of
At the request of the Department of Energy, Office of Energy Efficiency and Renewable Energy’s (DOE-EERE) Biomass Program, the National Research Council (NRC) convened a committee of 15 experts to examine the sustainable development of algal biofuels. The purpose of this study was to identify and anticipate potential sustainability concerns associated with a selected number of pathways for large-scale deployment of algal biofuels, discuss potential strategies for mitigating those concerns, and suggest indicators and metrics that could be used and data to be collected for assessing sustainability across the biofuel supply chain to monitor progress as the industry develops. In addition, the committee was asked to identify indicators that are most critical to address or have the greatest potential for improvement through DOE intervention and to suggest preferred cost and benefit analyses that could best aid in the decision-making process.
Paul T., Fundamental Changes to EPA’s
Research Enterprise: The Path Forward, Environmental Science and
Technology, 2012, 46, 580-586.
Since 2010, significant changes have been made to the U.S. Environmental Protection Agency’s (EPA) research enterprise. All of EPA’s actions and decisions are based on science and research. Whether it is crisis response, chemical assessment, or regulatory decision making, none of the Agency’s work to protect human health and the environment would be possible without the data, tools, science, and information provided by its researchers and the broader scientific community. The Agency has recently undertaken a major effort to realign its research portfolio in order to more effectively address pressing environmental challenges and better serve the Agency’s decision making functions into the future. Principles of the path forward include Sustainability, Systems, Integrated Trans-Disciplinary Research, Solutions, and Acting Catalytically. A program of Safe and Sustainable Water Resources is part of this initiative.
The Clean Water Act at 40, WE&T, OCTOBER 2012, Water Environment Federation.
special report reflects on the regulatory, technological, and financial
advances spurred by the Clean Water Act as well as looks forward to what’s next
for water quality and the sector.
Turning 40 is associated with reflection and renewal. Looking at the past, one makes changes, or at least resolutions, for the future. As we consider the 40th anniversary of the Clean Water Act (CWA), we in the water sector will construct a slideshow of happy memories and accomplishments: rivers and lakes returned to health, vibrant urban waterfronts, millions of Americans enjoying recreational opportunities in waterways they once would have avoided. These images are real, and CWA has resulted in tremendous progress. CWA commonly and rightfully is labeled the most successful of our national environmental statutes. But as we prepare to slice the birthday cake, many water professionals think CWA is beginning to show its age. They are frustrated by what many see as stalled progress and continuing difficulty in solving 2012’s water quality challenges — challenges that are not addressed very well under 1972’s law.
Specific suggestions for modernizing CWA have included:
• allowing for greater targeting of priority pollution on a watershed basis;
• better integrating of CWA and Safe Drinking Water Act (SDWA) requirements;
• using market-based solutions, such as water quality trading, incentives, or regulatory strategies, to encourage adoption of innovative technologies for point and nonpoint sources; and
• creating a new funding paradigm that provides adequate money for state administration of CWA and the capital projects undertaken by local governments.

Zakar, Muhammad Zakria, et al, Climage Change-Induced Water Scarcity: A Threat to Human Health, Research Journal of South Asian Studies, Vol. 27, No. 2, July-December 2012, pp. 293-312.
Climate change might affect the development of water scarcity least in some areas of the world. Water scarcity means not only the availability but also the quality of water and sanitation. Climate change might reduce the capacity of the state to provide health care to the population. Thereby, climate change has direct and indirect impacts on human security and hence health effects may result from (climate change induced) water scarcity. Mainly developing countries will be affected by water scarcity due to their population increase. Water scarcity may lead to a reduction of institutional resources and thereby to a lack in the health care system. Therefore, climate change causes different factors which may promote local and/or transnational conflicts. This impacts the human security and health. Even though climate change is not the only reason for water scarcity, it may affect political and social conflicts and has thereby impact on populations’ health.
Due to increasing concentration of carbon dioxide and other greenhouse gases in the atmosphere, several hydro-meteorological variables are likely to be significantly impacted. Reservoir operations, crop production, erosion processes, runoff production and many other hydrological processes are likely to be impacted by the ongoing climate change. This paper presents a comprehensive review of climate change impact on hydro-meteorological variables in several river basins around the world. The hydro-meteorological variables considered in this study include maximum temperature, minimum temperature, precipitation, and streamflow. A review of local weather generators to model hydrological impact of climate change has also been presented. Changes in the frequency of hydro-climatic extremes may be one of the most significant consequences of climate change. Therefore, a review of impacts of climate change on hydrological extremes has also been presented.

Even though it is probably true that in more recent times the water planning and management procedures used in most parts of the world appear to have been reasonably adequate, it is now becoming increasingly questionable. A sustainable approach is now required. Yet, it is quite one thing to say “sustainable” in every breath, and another to create a sustainable system when the definition is so vague. A number of questions will certainly have to be answered if water resources experts are to become successful ‘sustainable water resource developers’. Unified concepts for designing, operating, and maintaining water resource systems that could assure planners of a sustainable product are still to be developed.

Organization for Economic Cooperation and Development (OECD), Review of the Implementation of the OECD Environmental Strategy for the First Decade of the 21st Century, Making Green Growth Deliver, Meeting of the Environmental Policy Committee (EPOC) at Ministerial Level, 29-30 March 2012.
OECD Environment Ministers adopted the OECD Environmental Strategy for the First Decade of the 21st Century on 16 May 2001. The following day, the OECD Meeting of Council at Ministerial level endorsed the Strategy. At our meeting on 29-30 March 2012, we took stock of the progress that we have made over the intervening decade. This followed on from two interim reviews along the way. We submit this report to the OECD Council at Ministerial level on the lessons that can be learned to help guide future action. The Strategy was intended to provide directions for environmentally sustainable policies in OECD Member countries, and to guide the future work of the OECD in the field of environment. Given the multiple and cross-sectoral pressures on the environment, many of the policy actions identified in the Strategy fell outside the responsibility of Environment Ministries. Their implementation depended on a whole-of-government response.
The fundamental objective of the Strategy was to maintain ecosystem integrity, particularly climate, biodiversity and water. Four other objectives were also established: decoupling environmental pressures from economic growth (particularly in the energy, transport and agriculture sectors); improving information for decision-making; enhancing the interface of social and environmental policies; and improving global environmental governance and cooperation. Ten years on we must conclude that the objectives of the Strategy have not been fully achieved. Despite significant improvements on some environmental fronts, it is clear that much work remains. Environmental pressures have not been reduced to the extent needed to maintain ecosystem integrity and to ensure environmentally sustainable development. Although uncertainties remain about environmental thresholds, crossing them would entail real reductions in well-being and welfare. There is an urgent need for more ambitious policies to tackle environmental pressures. But such policies will only be acceptable and effective if they demonstrate that they take full account of economic and social considerations. For this reason, the active engagement of other Ministers will be essential, including those responsible for Finance, Economy and Trade, as well as the private sector, trade unions and NGOs.
The OECD Environmental Strategy is a living document that will continue to provide a reference for the Environment Policy Committee‟s Strategic Vision and guide its priorities. The OECD‟s Green Growth Strategy must now guide us and relevant OECD committees in integrating environmental and economic policies and pursuing green growth objectives.
Reza Ardakanian and Dirk Jaeger (eds.), Water and the Green Economy, Capacity Development Aspects, United Nations University, Water for Life, UN Water, May 2012.
book consists of 11 chapters that concern global aspects of water as it relates
to capacity development.
More and more societies are looking to transfer their economies into green economies. This begs questions such as what are the characteristics of a green economy, and what will it take to accomplish it with respect to capacity development needs within the water supply and sanitation sector?
While the “green
economy” concept still needs to be defined and agreed in detail, UNEP’s working
definition considers a green economy to be one which results in improved human
well-being and social equity, while significantly reducing environmental risks
and ecological scarcities: “In its simplest expression, a green economy can be
thought of as one which is low carbon, resource efficient and socially
inclusive”. Furthermore, the green
economy approach “seeks, in principle, to unite under a single banner the
entire suite of economic policies ... of relevance to sustainable development”.
As such, this approach includes already
approved holistic management approaches such as integrated water resources
management and combines principles of social inclusiveness, resource and energy
efficiency, while assuring biodiversity and sustainable ecosystem services.
In its Green Economy Report, UNEP2 (2011) provides six key messages with respect to water:
1. Water, a basic
necessity for sustaining life, goes undelivered to many of the world’s poor.
2. The existing inadequacies in provision of water and sanitation services generate considerable social costs and economic inefficiencies.
3. Continuing current
practices will lead to a massive and unsustainable gap between global supply
and demand for water withdrawal. This is exacerbated by failure to collect and
treat used water to enable subsequent uses.
4. The availability of an adequate quantity of water, of sufficient quality, is a service provided by ecosystems.
investment in water-dependent ecosystems, in water infrastructure and in water
management can be expected to expedite the transition to a green economy.
6. When investment is coupled with improvements in institutional arrangements, entitlement and allocation system, the expansion of Payments for Ecosystem Services (PES), and the improvement of water charging and finance arrangements, the amount that needs to be invested in water can be reduced significantly.
This book fills a gap in current knowledge when it comes to connecting capacity development, water, and green economy practices. Of particular importance are capacity development practices for knowledge transfer and adaption/adoption; capacity development practices for technology development/adoption/transfer; individual capacity development practices; and institutional capacity development practices.
April 30-May 1: The Institute of Medicine of the National Academies recently held a workshop on hydraulic fracturing for extraction of natural gas from shale rock formations. The link to the workshop may be found at http://www.iom.edu/frackingHIA, and the series of presentations is on the right-hand side of the page, organized by author last name.
Natural gas extraction from shale rock formations, which includes hydraulic fracturing (commonly referred to as “hydrofracking”), is increasingly in the news as the deployment of the technologies has expanded, rural communities have been transformed overnight, public awareness has increased, and regulations are developed. The expanding use of shale gas extraction across the United States occurs in a context in which there are demands to reduce greenhouse gas emissions, desires to decrease dependency on foreign energy, controversies over other energy sources like offshore drilling, nuclear energy, biofuels and the proposed Keystone pipeline, and slower advancements of renewables like wind and solar energy technologies.
Shale gas extraction in the
United States is an opportunity because of the existence of thermagenic methane reservoirs in
geologic formations such as the Marcellus and Utica shale formations. Formerly
inaccessible, the higher cost of petroleum based fuels has motivated efforts to extract and market this
methane at depths up to 7,000 feet. Because of the geology of the shale—at depths of at least 100
ft and with gas stored within natural fractures or joints rather than in large pools—conventional
gas extraction techniques are not effective. Hydrofracturing utilizes technological advances
in horizontal drilling and fracturing techniques. It differs from conventional gas extraction
techniques in that it involves: higher volume of fracking fluids (millions of gallons of fluid
versus less than 100,000 gallons of fluid) to stimulate gas release; directional drilling to access
more natural joints; the use of “slickwater” to allow for pumping over 1.5 to 2.0 miles of
horizontal pipe; and multi-well pads. Combining these technologies has made gas extraction from
organic-rich shale formations economically feasible in the last 15 years.

Government Accountability Office, Information on the Quantity, Quality, and Management of Water Produced During Oil and Gas Production, Report to the Ranking Member, Committee on Science, Space, and Technology, House of Representatives, GAO-12-156, January 2012.
A significant amount of water is produced daily as a byproduct from drilling of oil and gas. A 2009 Argonne National Laboratory study estimated that 56 million barrels of water are produced onshore every day, but this study may underestimate the current total volume because it is based on limited, and in some cases, incomplete data generated by the states. In general, the volume of produced water generated by a given well varies widely according to three key factors: the hydrocarbon being produced, the geographic location of the well, and the method of production used. For example, some gas wells typically generate large volumes of water early in production, whereas oil wells typically generate less. Generally, the quality of produced water from oil and gas production is poor, and it cannot be readily used for another purpose without prior treatment. The specific quality of water produced by a given well, however, can vary widely according to the same three factors that impact volume—hydrocarbon, geography, and production method.
Oil and gas producers can choose from a number of practices to manage and treat produced water, but underground injection is the predominant practice because it requires little or no treatment and is often the least costly option. According to federal estimates, more than 90 percent of produced water is managed by injecting it into wells that are designated to receive produced water. A limited amount of produced water is disposed of or reused by producers in other ways, including discharging it to surface water, storing it in surface impoundments or ponds so that it can evaporate, irrigating crops, and reusing it for hydraulic fracturing. Managing produced water in these ways can require more advanced treatment methods, such as distillation. How produced water is ultimately managed and treated is primarily an economic decision, made within the bounds of federal and state regulations.
The management of produced water through underground injection is subject to the Safe Drinking Water Act’s Underground Injection Control program, which is designed to prevent contamination of aquifers that supply public water systems by ensuring the safe operation of injection wells. Under this program, the Environmental Protection Agency (EPA) or the states require producers to obtain permits for their injection wells by, among other things, meeting technical standards for constructing, operating, and testing and monitoring the wells. EPA also regulates the management of produced water through surface discharges under the Clean Water Act. Other management practices, such as disposal of the water into surface impoundments, irrigation, and the reuse of the water for hydraulic fracturing, are regulated by state authorities.
Several federal agencies, including EPA; the Department of Interior’s Bureau of Reclamation and U.S. Geological Survey; and a number of Department of Energy national laboratories, have undertaken research and development efforts related to produced water. These efforts have included sponsoring and issuing studies that describe the volume and quality of produced water, options for managing produced water and associated regulatory issues, as well as options for improving existing technologies for treating produced water and developing new technologies, such as more cost-effective filters.

Seperovic, Enes and Alma Imamovic, Bosnia and Herzegovina Within the Concept of Transboundary River Basin Management, ISSN 1512-5785, 2011.
Transboundary river basin management is a challenge everywhere in the world. EU Water Framework Directive set principles and objectives of transboundary river basin management for EU member states but usually followed by non-members states sharing with them river basins. Bosnia and Herzegovina has taken direction towards cooperation on transboundary river basin management as member of commissions and signing bilateral agreements. Due to the complex institutional arrangements of water management sector in BH problems, related to the activities within the international bodies such as ICPDR, exist. Recommendations for improvements of transboundary river basin management are dominantly related to the improvements within the country’s water management sector. Understanding and positive attitude towards good cooperation with riparian countries is present in BH.
Azmi, Mohammad, et al, A National-Scale Assessment of Agricultural Development Feasibility Using Multi-Criteria Decision Making (MCDM) Approaches, Advances in Natural and Applied Sciences, 5(4): 445-457, 2011.
Problem Oriented Approach in Integrated Water Resources Management (IWRM), requires that outcomes of water resources development be assessed based on water resources sustainability at basin level. In planning models, assessment of options and structural and non-structural actions and plans are also assessable based on the variations of these criteria in view of the current situation. Hence, study and prioritization of options in Iran entails the selection and measurement of water resources sustainability criteria at basin level. Agriculture sector as the world’s main consumer of water has a significant role in water allocation in different countries. In the present study, three multi-criteria decision making methods of AHP, TOPSIS and ELECTRE have been used to rank the feasibility of agricultural development in second order basins of Iran. Next, existing trend of agricultural development will be compared with the obtained rankings of MCDM methods. Results reveal that there are signs of agricultural disharmonious and unsustainable development in some of second order basins of Iran.

framework is built, wherein hydrological/water quality model is used to measure
watershed sustainability. For this framework, watershed sustainability has been
defined and quantified by defining social, environmental and biodiversity indicators.
By providing weights to these indicators, a “River Basin Sustainability Index”
is built. The watershed sustainability is then calculated based on the concepts
of reliability, resilience and vulnerability.
The framework is then applied to a case study, where, based on watershed management principles, four land use scenarios are created in GIS. The Soil and Water Assessment Tool (SWAT) is used as a hydrology/water quality model. Based on the results the land uses are ranked for sustainability and pol-icy implications have been discussed. This results show that land use (both type and location) impact watershed sustainability. The existing land use is weak in environmental sustainability. Also, riparian zones play a critical role in watershed sustainability, although beyond certain width their contribution is not significant.
Venkateswarlu, Climate Change: Adaptation
and Mitigation Strategies in Rainfed Agriculture, Delhi, Feb. 7-9, 2011.
Climate change impacts on agriculture are being witnessed all over the world, but countries like India are more vulnerable in view of the high population depending on agriculture and excessive pressure on natural resources. The warming trend in India over the past 100 years (1901 to 2007) was observed to be 0.510 C with accelerated warming of 0.21oC per every10 years since 1970.
projected impacts are likely to further aggravate yield fluctuations of many
crops with impact on food security and prices. Cereal productivity is projected
to decrease by 10-40% by 2100 and greater loss is expected in rabi.
There are already evidences of negative impacts on yield of wheat and paddy in
parts of India due to increased temperature, increasing water stress and
reduction in number of rainy days.
Modeling studies project a significant decrease in cereal production by the end of this century. Climate change impacts are likely to vary in different parts of the country. Parts of western Rajasthan, Southern Gujarat, Madhya Pradesh, Maharashtra, Northern Karnataka, Northern Andhra Pradesh, and Southern Bihar are likely to be more vulnerable in terms of extreme events. For every one degree increase in temperature, yields of wheat, soybean, mustard, groundnut and potato are expected to decline by 3-7%. Similarly, rice yields may decline by 6% for every one degree increase in temperature. Water requirement of crops is also likely to go up with projected warming and extreme events are likely to increase.

for a precious resource. A report of the Energy and Water in a Warming
World initiative. Cambridge, MA: Union of Concerned Scientists. November 2011.
This report—the first on power plant water use and related water stress from the Energy and Water in a Warming World initiative—is the first systematic assessment of both the effects of power plant cooling on water resources across the United States and the quality of information available to help public- and private-sector decision makers make water-smart energy choices.
analysis starts by profiling the water use characteristics of virtually every
electricity generator in the United States. Then, applying new analytical
approaches, we conservatively estimate the water use of those generators in
2008, looking across the range of fuels, power plant technologies, and cooling
systems. We then use those results to assess the stress that power plant water use
placed on water systems across the country.
We also compare our results with those reported by power plant operators to the U.S. Energy Information Administration (EIA) for 2008. We examine both the withdrawal and consumption of freshwater. Withdrawal is the total amount of water a power plant takes in from a source such as a river, lake, or aquifer, some of which is returned. Consumption is the amount lost to evaporation during the cooling process. Withdrawal is important for several reasons. Water intake systems can trap fish and other aquatic wildlife. Water withdrawn for cooling but not consumed returns to the environment at a higher temperature, potentially harming fish and other wildlife. And when power plants tap groundwater for cooling, they can deplete aquifers critical for meeting many different needs. Consumption is important because it too reduces the amount of water available for other uses, including sustaining ecosystems.
Climate Change Adaptation, Federal Efforts to Provide Information Could Help Government Decision Making, Government Accountability Office, Testimony Before the Subcommittee on Oceans, Atmosphere, Fisheries, and Coast Guard, Committee on Commerce, Science, and Transportation, U.S. Senate, Nov. 16, 2011.
This testimony addresses (1) the data challenges that federal, state, and local officials face in their efforts to adapt to a changing climate, (2) the actions federal agencies could take to help address these challenges, and (3) federal climate change strategic planning efforts. The information in this testimony is based on prior work, largely on GAO’s recent reports on climate change adaptation (GAO-10-113) and federal climate change funding (GAO-11-317). These reports are based on, among other things, analysis of studies, site visits to areas pursuing adaptation efforts, and responses to a web-based questionnaire sent to federal, state, and local officials.

Profound pressure on water resources affects health, the economy and sustainable development. Industrialization, intensification of agriculture and growing populations followed by increases in water demands accentuate the necessity for sufficient high-quality water resources. Conflicts between amount of use and availability, coupled with all the driving forces and pressures on the quality of water resources highlite the need for sustainable management of water resources.
Yang, et al, Prioritization of Water
Management Under Climate Change and Urbanization Using Multi-Criteria Decision
Making Methods, Hydrology and Earth System Sciences Discussions, 8,
This paper quantifies the transformed effectiveness of alternatives for watershed management caused by climate change and urbanization and prioritizes five options using multi-criteria decision making techniques. The climate change scenarios (A1B and 5 A2) were obtained by using a statistical downscaling model (SDSM), and the urbanization scenario by surveying the existing urban planning. The flow and biochemical oxygen demand (BOD) concentration duration curves were derived, and the numbers of days required to satisfy the environmental flow requirement and the target BOD concentration were counted using the Hydrological Simulation Program-Fortran (HSPF) 10 model. In addition, five feasible alternatives were prioritized by using multi-criteria decision making techniques, based on the driving force-pressure-state-impact-response (DPSIR) framework and cost component. Finally, a sensitivity analysis approach for MCDM methods was conducted to reduce the uncertainty of weights. The result indicates that the most sensitive decision criterion is cost, followed by criteria response, 15 driving force, impact, state and pressure in that order. Since it is certain that the importance of cost component is over 0.127, use of the groundwater collected by subway stations will be the most preferred alternative in this application. All applications are carried out on watersheds in Korea.

Burke, Sophia, et al, Migration and Global Environmental Change: Quantifying Change in Ecosystem Services and Exposure to Hazards in the Mediterranean Basin Over the Next 50 Years That Might Be Relevant to Migration, Kings College London, UK, Oct. 2011.
This report examines the environmental drivers of migration in the
Mediterranean, with particular focus on the role of ecosystem services and the
impact of environmental hazards as potential push and pull factors.
Environmental drivers are just one set of potential drivers for migration
described in the Foresight ‘drivers of migration’ pentagon alongside
demographic, social, political and economic drivers. In the complex and diverse
Mediterranean political, social and economic landscapes, environmental drivers
rarely work in isolation of the other drivers, except in rare cases of
migration forced by hazard.
Nevertheless, environment plays a part and so we must consider how environmental drivers help to define the ecosystem services and disservices (such as hazards) that might combine with political, social and economic factors to provide push or pull conditions which then encourage migration. Moreover, the environment is rarely static and, given pressures on the global environment in general and the Mediterranean environment in particular, we need to analyze how ecosystem service provision and hazardscapes might change in the future and what the potential implications of such change might be for encouraging particular types of migration.
The substantial role of non-environmental drivers (i.e. politics, social, cultural and economic factors) is covered by a separate report.
Mehan, G. Tracy III, The Business of Water: It is Time to Embrace a New Model for Water Services, Bureau of National Affairs, 2011.
Water utilities in America are facing the sobering truth that there is nowhere else to turn other than to a model of business self-sufficiency for the financial and technical resources necessary to carry out their mission, according to G. Tracy Mehan III, the author of this article. He says that in a strange twist of fate, water utilities must become more business-like in how they value their water, wastewater, and more critically, their very sophisticated and capital-intensive services. They will have to manage water demand as much as water supply, and price the resources effectively while accounting for the poor and needy within their service areas.
This article is written in conjunction with the Second Annual Water Resources Summit, ‘‘Sustaining Our Nation’s Water Resources Summit—Answering the Call for Stewardship,’’ sponsored by The Horinko Group.

Asthana, Vandana and A.C. Shukla, The Logistics of Developmental and Water Governance in India, Prepared for the Fourth Annual Critical Studies Conference, Sept. 7-11, 2011.
This paper covers water policy in the region of Delhi in India. There are many policy pressures associated with production processes that have resulted from globalization. In addition to the concept of planned intervention to form policy, it is important to study the result of overlap among local, sub-national, national, and global scales as well as how inclusion or exclusion affects water policy. The interaction among all these levels helps to determine how a particular version of water policy achieves legitimacy. A close examination of these interactions aids in understanding how power mediates policy processes. In this view, water policy is largely about how actions determine the possibility of change in what the actors do. Therefore, making water policy involves the application of expertise and institutional techniques that affect how water is used.

Policies and Options for Water Use in Improved Areas in Egypt, Options Mediterrannées, A n° 98, 2011 ─ Dialogues
on Mediterranean water challenges: Rational water use, water price versus value
and lessons learned from the European Water Framework Directive.
The problem of water scarcity is complex, as it includes climate change, desertification, as well as increased demand by different water user sectors. The concept of sustainable water use is based on three main issues, economic efficiency, social equity and environmental integrity. The vision of the Ministry of Water Resources and Irrigation is that a new approach of water management is needed to consider the diverse range of resource-use features and its interactions to elaborate sustainable water resources management strategies. The study presented here concentrates on these aspects in general and gives some findings on water saving options in the improved areas of Egypt. It reflects on the actual approaches to water saving strategies. Therefore the current state of water management policies, indicator development and participation approaches was investigated. The implementation of an effective integrated strategy or policy for water management, and water saving, needs also to be based on a comprehensive and integrated assessment of the water bodies. At the same time, successful practices of water use need to be disseminated. It is essential to enable a quantification and qualification of system aspects for successful evaluation.
Tenhunen, John, et al, TERRECO: A Flux-Based Approach to Understanding Landscape Change, Potentials of Resilience and Sustainability in Ecosystem Services, 2011 TERRECO Science Conference October 2 – 7, 2011; Karlsruhe Institute of Technology, Garmisch-Partenkirchen, Germany.
The Millenium Assessment has provided a broad perspective on the ways and degree to which global change has stressed ecosystems and their potential to deliver goods and services to mankind. Management of natural resources at regional scale requires a clear understanding of the ways that ongoing human activities modify or create new system stressors, leading to net gains or losses in ecosystem services.
Ever since information from the
International Biological Program (IBP) was summarized in the 1960s, we know
that ecosystem stress response, recovery and resilience are related to changes
in ecosystem turnover of materials, nutrient retention or loss, resource use
efficiencies, and additional ecosystem properties that determine fluxes of
carbon, water and nutrients (Odum 1969, 1985). At landscape or regional scale,
changes in system drivers influence land-surface to atmosphere gas exchange
(water, carbon and trace gas emissions), the seasonal course of soil resource
stores, hydrology, and transport of nutrients and carbon into and through river
systems. In today’s terminology, shifts in these fluxes indicate a modification
of potential ecosystem services provided to us by the landscape or region of
interest, and upon which we depend.
Ongoing modeling efforts of the TERRECO project (DFG GRK1565) carried out in S. Korea focus on describing landscape and regional level flow networks for carbon, water, and nutrients, but in addition monetary flows associated with gains and losses in ecosystem services. The description is embedded within a framework which examines the trade-offs between agricultural intensification versus yield of high quality water to reservoirs for drinking water supply. The models also quantify hypothetical changes in flow networks that would occur in the context of climate, land use and social change scenarios.
Shadrack, Vulnerability of Peoples
Livelihoods to Water Resources Availability in Semi Arid Areas of Tanzania,
Journal of Water Resource and Protection, 2011, 3, 678-685 doi:10.4236/jwarp.2011.39078
Published Online September 2011 (http://www.SciRP.org/journal/jwarp).
In semi-arid areas of Tanzania vulnerability context is depicted as the starting component for policy process analysis through the sustainable livelihood approach. Giving vulnerability a high prominence in this analysis allowed the research to consider all kinds of vulnerabilities as central issues to the ways in which livelihoods are shaped. Hence the Sustainable Livelihood framework was used in this research as the comprehensive framework for assessing the contributing factors to limited water resources availability to sustain people’s livelihoods. The study revealed that, changes in the quantity, timing, intensity and duration of rainfall as a result of climate change contributes to greater water stress and making people more vulnerable. Due to over-abstraction upstream of the Great Ruaha River, it implies that, people depending on the water resources downstream of the Great Ruaha River catchment are vulnerable. Their livelihoods are at risks as they don’t have water for irrigation and other economic activities. The study also revealed that, both vulnerability and livelihood strategies are derived through natural water availability which features droughts, climate change and the link between water availability, agricultural production, and outcomes.

unprecedented about the final decade or so of the 20th Century was not so much
the pace of change in technology — which supposedly is always “unprecedented” —
but our collective willingness to question whether Man had got his relationship
with the Environment “about right”. It was as though the rarity of the approach
of a new millennium had evoked just as uncommon and profound a questioning, no
less so for water professionals and environmental engineers than for people
from all manner of other walks of life.
This Sustainability Concepts Paper is marked by that experience. Having become used to decades of the water-based paradigm, for removing the biological residuals of the city’s metabolism and returning them to the aquatic environment, we had ceased to question what might otherwise have been — had the water closet not been so successful at some critical juncture in the competitive technological stakes of the mid-19th Century. The Paper takes this experience of the “great sustainability debate” of the 1990s, first to record the role of customary environmental engineering therein — almost its fall from grace by default — and, second, to set out a vision and challenge for it.
Hipel, Keith, et al, Water Resources in Canada: A Strategic Viewpoint, Report to the Inter American National Academies of Science, 2011.
All levels of government in Canada should adopt an adaptive, integrative and participatory approach to water governance from a systems thinking perspective for proactively addressing existing strategic water problems as well as unforeseen difficulties that will arise in the future. In consultation with all levels of government and key stakeholders, Canada should develop a comprehensive national water policy that reflects the values of Canadians and has precedence over international trading agreements. Because of its vastness and the rich diversity of climate regions and ecosystems, Canada has many regional water problems to solve such as melting glaciers in the Rocky Mountains, droughts in the Prairies, high water demand in the oil sands, flooding in Manitoba, fluctuating water levels and pollution in the Great Lakes, expanded hydroelectric power developments in northern Quebec and Labrador, and the threat of water exports, especially from the Great Lakes. A wide variety of challenging water related problems to tackle occur in many regions of Canada: groundwater overexploitation, contaminants of emerging concern, brownfield prevention and redevelopment, bottled water, and the increasing negative impacts of climate change. Accordingly, specific recommendations are put forward for achieving enlightened water governance in Canada as well as internationally. Moreover, connected governance innovations related to climate change, energy and trade are also formulated.
Ximing Cai, et al, Can Water Allocation in the Yellow River Basin Be Improved?, International Food Policy Research Institute, Discussion Paper 01117, 2011.
In 1999, the Government of China enforced a cross-provincial, quota-based Water Allocation Agreement that was developed in 1987 and titled Unified Water Flow Regulation (UWFR) to ensure that flow to the Yellow River mouth would not be cut off. This policy was in line with the refocus of the Government, over the last decade, on sustainable water use and keeping the Yellow River healthy. The policy enforcement ended more than two decades of flow-cutoffs, that is, periods when the Yellow River did not reach the Bohai Sea at its mouth, during an increasing number of days every year. While the UWFR was an important step forward in protecting the water resources in Northern China, the allocation did not take into account the value of water in various uses and water users who had to give up water resources, chiefly irrigators in the upstream and midstream provinces were not compensated. Could alternative water management options have brought about a better outcome for irrigators and the downstream ecosystem? We analyze this question using a Multi-Agent System (MAS) modeling framework for the Yellow River Basin (YRB). We find that compared to the baseline scenario simulating UWFR management, water trading among irrigation districts would result in a small decline in water consumption, a significant increase in agricultural GDP, and a small increase in total basin GDP. Overall GDP increase would be much higher if domestic and industrial uses became active water trading sectors.
Varela-Ortega, Consuelo, Participatory Modeling for Sustainable Development in Water and Agrarian Systems: Potential and Limits of Stakeholder Involvement, EAAE 2011 Congress, Change and Uncertainty, Zurich, Switzerland, 2011.
Public participation is increasingly advocated as a necessary feature of natural resources management. The EU Water Framework Directive (WFD) is such an example, as it prescribes participatory processes as necessary features in basin management plans. The rationale behind this mandate is that involving interest groups ideally yields higher-quality decisions, which are arguably more likely to meet public acceptance. Furthermore, failing to involve stakeholders in policy-making might hamper the implementation of management initiatives, as controversial decisions can lead pressure lobbies to generate public opposition.
approach to public participation is to hold open meetings for groups or
individuals to provide input. While these strategies have been used for decades,
they are not necessarily sufficient for some processes as they are frequently
biased towards the interests of participants of well-organized place-based
groups. Hence, public participation has developed into an expanding body of
knowledge that comprises a variety of techniques and practices. For instance,
wherever significant uncertainties exist ongoing stakeholder participation
might be needed to address management and governance problems adequately. Joint
involvement of water managers, stakeholders and experts may in turn require
decision support tools that build on transparency and flexibility to reach
sound action plans and instruments.
While participatory processes should ideally empower participants to have a direct impact on policy, this can be difficult in regions where a participatory tradition is lacking. This is particularly true if competing uses make the setting at hand a conflicting one. Following upon this argument, this paper explores the role of an informal public participation process held in the Upper Guadiana basin, Spain. It is hypothesized that informal, non-binding fora might provide valuable additions to conflictive contexts, not only contributing to broaden the knowledge about the basin under consideration, but also facilitating adaptation to socio-economic and environmental challenges.

Victor Pochat, International
Agreements, Institutions and Projects in La Plata River Basin, International Journal of Water Resources Development, 27:3, 497-510,
La Plata River basin is one of the most important river systems in the world, mainly due to its degree of development. In 1967, the Intergovernmental Coordinating Committee of La Plata Basin Countries (CIC) was established and, two years later, the riparian countries signed the La Plata Basin Treaty, broadly comprehensive regarding its competence, as well as a framework agreement which has facilitated the implementation of numerous bilateral or multilateral agreements that characterize the current state of co-operation. Since the 1990s, with support from international organizations, a number of projects—at sub-basin or river level—have been carried out, and, in 2001, the development of a Framework Programme for the La Plata basin was agreed. The strengthening of CIC in order to foster synergies among the different institutions and projects towards an integrated basin management approach is expected.

Blanco-Gutierrez, Irene, et al, Integrated Economic-Hydrologic Analysis of Policy Responses to Promote Sustainable Water Use Under Changing Climatic Conditions, 2011 EAAE Congress, Change and Uncertainty, Zurich, Switzerland, 2011.
Water is a vital resource, but also a critical limiting factor for economic and social development in many parts of the world. The recent rapid growth in human population and water use for social and economic development is increasing the pressure on water resources and the environment, as well as leading to growing conflicts among competing water use sectors (agriculture, urban, tourism, industry) and regions. In Spain, as in many other arid and semi-arid regions affected by drought and wide climate variability, irrigated agriculture is responsible for most consumptive water use and plays an important role in sustaining rural livelihoods. Historically, the evolution of irrigation has been based on publicly-funded irrigation development plans that promoted economic growth and improved the socio-economic conditions of rural farmers in agrarian Spain, but increased environmental damage and led to excessive and inefficient exploitation of water resources.
The present study analyzes the effects of national and European water policies under normal and dry climate conditions, using a novel hydro-economic model based on the integration of a multiscale economic optimization model and a hydrology water management simulation model built in WEAP. Application of the model was carried out in the Middle Guadiana basin, a surface irrigated area located on the south-western of the Iberian Peninsula in Spain.

Both environmental and human challenges, such as deforestation and desertification, require scientifically sound simulations of physical phenomena to better understand the past and to better predict future trends for improved decision support. However, many scientific problems cannot be processed using a single computer and require computing capability from many distributed computers. The problems should be solved by interdisciplinary efforts instead of by a single science community. Using dust storm forecasting as a case study, the study investigates how interoperability technologies can facilitate data access service, model input integration, model coupling, and output utilization and dissemination.

Integrated Water Resources Management (IWRM) is one example of integrated approach to natural resources management that has been widely promoted during the past decades. In this thesis, IWRM is understood as a strategic management procedure that integrates the natural resources and society (users and institutions) around a body of water. Numerous international conferences and meetings have promoted IWRM as a key approach to water management and subsequently a way to sustainable development. Yet, practical implementation of IWRM on the ground has had uneven success.

that Cause Water Pollution, 2011 International Conference on Environmental
and Agricultural Engineering, IACSIT Press, Singapore, 2011.
There are many water quality problems in both developing and developed countries. Of all the environmental concerns that developing countries face, the lack of adequate water of good quality is probably the most serious. The sustainable management of water quality has policy, technical, institutional and financial components. In many developing countries restricted funding is usually combined with fragile or unstable institutions and limited technical capabilities to deal with an expanding range of water quality problems. At the technical level, there has been great progress in western nations in developing more cost effective monitoring, analytical protocols, and assessment methods. This flows not only from better scientific knowledge, but also from recognition that conventional monitoring programs are inefficient, expensive, and often not very useful. Regrettably, financial institutions and ODA programs tend to reinforce conventional approaches in developing countries with the result that these countries have little opportunity to develop a new, more appropriate and more sustainable data paradigm. In lesser developed countries where public health is the major concern, the traditional model of a centralized monitoring program often does not work, suggesting that a new model of decentralized community-based monitoring would be more effective.
ROS, LY Tem, and Anna Thompson, Catchment
Governance and Cooperation Dilemmas: A Case Study from Cambodia, CDRI
Policy Brief 2011, No. 9.
A catchment or river basin refers to an area of land that is drained by a single river and its tributaries. Integral to the health of a catchment are elements such as soil, water, wildlife and vegetation, all of which form a life support ecosystem. Modern global catchment governance policy has turned to the theory of Integrated Catchment Management (ICM) in the last three decades. Such policy is soon to be introduced in Cambodia as a means to achieve sustainable water resources management at catchment level. This approach recognizes the importance of cooperation between all stakeholders within a catchment, based on the perspective that a catchment is a relevant territorial space which cuts across pre-existing administrative boundaries containing different groups of users and governance systems.
Coulibaly, Naga, An Opensource GIS Tool for Integrated Water Resources Management (IWRM) in a Basin, Indian Institute of Technology, Bombay, 2011.
Challenges faced by more and more countries in their struggle for economic and social development are increasingly related to water. Growth in population, increased economic activity and improved standards of living lead to increased competition for and conflicts over the limited freshwater resource. Also, water pollution is inherently connected with human activities linked to domestic, agricultural and industrial wastes. Integrated Water Resources Management (IWRM) is a process which can assist countries in their endeavor to deal with water issues in a cost-effective and sustainable way.
This study aims to design a prototype of Decision Support System (DSS) using free and open source software which allows management and analysis of current and historical data for a sustainable management of water resource in a drainage basin. Specifically it is to collect water resources, socio-economic and environmental data, design and implement a database and create a Spatial Decision Support System for water management.
Maskey, Stuty, Using the Advocacy Coalition Framework to Understand Challenges in Urban Water Policy Reforms: A Case Study of the Melamchi Water Supply Project in Nepal, Oregon State University, 2011.
The Himalayan mountain range is one of the world’s largest sources of fresh water, and Nepal, situated at the foothills of the Himalayas, is endowed with ample water resources. In spite of this water abundance, drinking water supply in many parts of the country is inadequate, particularly in the capital, Kathmandu Valley. For a long time now, Kathmandu residents have been struggling with an increasing urban water shortage. In 2000, as a part of the urban water sector reform program, the Government of Nepal (GoN) entered into a loan agreement with the Asian Development Bank (ADB) to construct the multi‐million dollar Melamchi Water Supply Project.
This Project provides a sound case study to understand urban water policy challenges in Nepal. This much‐hyped project has been mired in controversy ever since its inception and subsequent loan‐agreement. The development of the project was halted due to numerous controversies ranging from charges of social injustice to environmental concerns, and the project deadline has been revised more than three times.
This paper analyzes how differences in beliefs and values lead to the formation of conflicting coalitions that stand firm to protect their core beliefs. By applying the Advocacy Coalition Framework, this paper then examines how coalitions interact, negotiate, reorganize, and adapt to changing policy conditions, to survive and to advance the policy making process.
BP Barber, Water Resources Master Plan for the Laurens County Water and Sewer Commission, Laurens, South Carolina, 2011.
Located between Greenville and Columbia, Laurens County is in a position to benefit economically from its location in the upstate of South Carolina. To take advantage of potential economic opportunities, the County will need adequate water and wastewater systems to support potential growth. The resources required to effectively operate these systems will need to be developed and managed properly to maintain a high quality of life for the residents of the County. To provide guidance for sustainable development and management of the County’s Water Resources, the Laurens County Water and Sewer Commission (LCWSC) authorized BP Barber to assist with preparation of a Water Resources Master Plan. This report documents the work, findings, and recommendations developed as part of this planning process. An overview of each Section in the report is provided in this Executive Summary.
Nelson, Robert H., The New Holy Wars, Economic Religion vs. Environmental Religion in Contemporary America, Pennsylvania State University Press, 2011, Book Review by G. Tracy Mehan III.
Excerpt: The author “aims to deconstruct modern economics and the environmental movement, purporting to reveal them as literal religions. These are attenuated Protestant sects, “Calvinism minus God,” complete with a Creation story, Garden of Eden, the Fall, and a path to Salvation.” The review also includes a discussion of the 2005 documentary /Grizzly Man/ by the German director Werner Herzog which might involve another kind of “secular theology” as described by Nelson.
Government Accountability Office, Climate Change Adaptation, Aligning Funding with Strategic Priorities, Testimony Before the Subcommittee on Financial Services and General Government, Committee on Appropriations, U.S. Senate, GAO-11-876T, 2011.
This testimony addresses (1) the actions federal, state, and local authorities are taking to adapt to climate change; (2) the challenges that federal, state, and local officials face in their efforts to adapt and actions federal agencies could take to help address these challenges; and (3) the extent to which federal funding for adaptation and other climate change activities is consistently tracked and reported and aligned with strategic priorities. The information in this testimony is based on prior work, largely on GAO’s recent reports on climate change adaptation and federal climate change funding.
Andrea Rodriguez, Adaptation Funding to
Climate Change under the Global Environment Facility: An Analysis of Bolivia’s
Adaptation Projects, Uppsala University, 2010
Adaptation finance has recently become an essential component to address international climate change impacts. The Global Environment Facility (GEF) is the main mechanism providing financial adaptation assistance from developed to developing countries. Under this mechanism, Bolivia figures as the country with more projects than any other eligible country, giving the impression that Bolivia receives favorable treatment when resources are allocated. This study analyzes the process by which Bolivia receives funding for adaptation projects using the principle of good governance and elements of accountability, fairness and effectiveness in the allocation of resources, to understand how such adaptation projects are granted.
Rezaian, Sahar, et al, Water Consumption Management using WEAP&Conceptual Models, Case Study: Golestan Province, Iran, 2011 2nd International Conference on Environmental Science and Development, Singapore
Iran is located among the world’s arid and semiarid lands climatically, so its water consumption management is of vital importance. Golestan province as one of the important poles of Iran’s farming and agricultural products is not excluded and in terms of water supply has not a desirable situation. Due to over pumping and reduction in precipitation, groundwater reserves have not been in satisfactory condition. Exploitation of surface water does not conform to any management principle as well. On the other hand due to population growth, development of agricultural and industrial activities, as well as decreasing trend of water resources, setting up a principled approach for water consumption is an undeniable fact. In this study, water supply sources were identified in various parts of the region. Consequently, the role of major water consumption sections in the quantitative change of water resources was determined. Finally the obtained results were used to project the conceptual model for quantitative changes of water resources in order to achieve sustainable development in different parts of this province. The result of the conceptual model shows that about 371.51million cubic meters of water in Golestan province is lost due to lack of adequate reserves. On the other hand, reviews of different management scenarios indicated that the problem of water shortages in this province cannot be resolved alone with construction of new dams. Meanwhile a modified consumption pattern is considered as an effective and complementary step in sustainable water consumption management.
Kragt, Marit E., et al, How Integrative Modeling Can Break Down Disciplinary Silos, University of Western Australia, Working Paper 1121, Crawley, Australia, 2011
Effective management of environmental systems requires assessments of multiple (physical, ecological, and socio-economic) issues and integration of knowledge from various disciplinary experts. Integrative research faces widely acknowledged theoretical and practical challenges. In this paper, we argue that model development aimed at integrating multidisciplinary inputs can overcome many of these difficulties. Environmental models can act as a shared goal and provide a framework for successful integrative research. Modellers often have the more generalist background and overarching perspective required to develop a shared understanding of a system. Modellers are therefore well-placed to facilitate integrative processes. We discuss the challenges of integrative research and discuss how modellers, and model development, can facilitate successful integration through: definition of common research questions and objectives; conceptual modelling; identification of project participants; aligning terminologies; and stressing the importance of communication and trust.

Mehan, G. Tracy III, A Symphonic Approach to Water Management: The Quest for New Models of Watershed Governance, J. of Land Use and Environmental Law, Florida State University, 2010
While the largest of the nation’s watersheds will be governed according to their own tailor-made ways, the most common, logical means of effectuating a symphonic watershed governance model across the country is through the instrumentality of water, wastewater, and stormwater utilities that need to assume a greater leadership role in their respective home watersheds. This requires that utility managers redefine their roles in terms of watershed protection, community involvement, and facilities management. Simply managing a facility is no longer sufficient. The problem extends far beyond their immediate service area to the entire basin, catchment, drainage or watershed.
Hussain, Ijaz, Water Demand Management and Economic Value of Water in the Indus Basin, Department of Economics, University of Sargodha, Pakistan, 2007
The present study was conducted on Water Demand Management and Economic Value of Water in the Indus Basin. To fulfill the objective of the study secondary and primary data sets were used. The primary data for study was collected through a farm survey of nearly 120 farmers on distributaries in Sargodha district. The data for supply and demand was taken from secondary sources. The sources include but not limited to the Agricultural Statistics of Pakistan, 2005-06, Economic Survey, 2006, the Water and Power Development Authority. The crop yield stress data was taken from Mona Reclamation project and Punjab Agriculture Research Institute, Faisalabad. Water supply and demand was estimated by using water balance equations.
In order to calculate the Economic Value of Irrigation Water residual imputation approach was used. The change in net income method can be adapted to mathematical programming models (LP model) of farm situations to approximate a functional relationship between net benefits and irrigation water use .
Waslekar, S., The Blue Peace, Rethinking Middle East Water, Strategic Foresight Group, C-306, Mumbai, India, 2011.
The issue of access to water resources, particularly in lean seasons, will impact the way political relations and alliances are framed in the future, even more significantly than it already does. The costs of failing to manage water are counted in terms of poverty, conflict, impaired growth and lost biodiversity. New political behavioral norms and processes are emerging. What was common sense and vision in the past is no longer the case. What can be agreed upon today and tomorrow is not the same as before. The conditions have changed in a way that the solutions of the past are not effective anymore. The rules of the game are evolving at an unprecedented speed. The response is not easy. It is all about fostering a new diplomacy, the “blue diplomacy” with the objective of fostering the blue peace.

Ritzma, H.P., Adapting to Climate Change: Examples from the Netherlands, Wageningen University and Research Centre, Wageningen, the Netherlands, 2011.
In the Netherlands, adaptation measures focus on the water management system as well as the spatial planning. The selection of adaptation measures mainly depends on the type of land use. For the three major types of land types, i.e. the low-lying peatlands in the western part of the country, the higher sandy soil areas in the east and southeast and the marine clay areas in the reclaimed polder areas, adaptation measures, for both agriculture and nature, adaption strategies are discussed are discussed.
Mahmud-ul-Islam, S., Land Use Change Detection of the Buriganga River (Bangladesh) Using GIS Tools and its Water Management for Promoting a Sustainable Environment, ISSN 1651-064X, Royal Institute of Technology, Stockholm, Sweden, 2011.
This research work recommends promoting a sustainable environment in the Dhaka city area and healthier life for its inhabitants. It is essential to save the surrounding river system especially the Buriganga River. An integrated river basin organization is highly necessary to implement an IWRM approach to save the river. The present study reveals that a governmental weak institutional setup and lack of enforcement of existing laws and policy are the main obstructions to saving the Buriganga River.
Glassman, Diana, et al, The Water-Energy Nexus, Adding Water to the Energy Agenda, World Policy Institute, March 2011.
To enhance the quality of discussion and decision-making on the water-energy nexus, this policy paper provides the context needed to evaluate key tradeoffs. We present a comprehensive, user friendly guide to the most credible available data about water consumption per unit of energy produced across a spectrum of traditional and alternative energy technologies. We identify data holes and important issues that merit further attention. We also have created a glossary to help non-experts decipher energy jargon.
Based on existing data, the most startling finding is that (with some notable exceptions) both traditional and existing alternative energy technologies are evolving toward higher water consumption per unit of energy produced.
Both emerging petroleum and alternative transportation fuels consume more water than conventional petroleum-based fuels:
• Petroleum from the Canadian oil sands extracted via surface mining techniques can consume 20 times more water than conventional oil drilling. As a specific example of an underlying data weakness, this figure excludes the increasingly important steam-assisted gravity drainage technique (SAGD) method. We encourage future researchers to fill this hole.
• Irrigated first-generation soy- and corn-based biofuels can consume thousands of times more water than traditional oil drilling, primarily through irrigation. More research is needed to evaluate second and third generation biofuels.
The picture on electricity generation is mixed:
• Among conventional power plants, gas-fired plants consume the least amount of water per unit of energy produced. Coal- and oil-fired plants consume roughly twice as much water as gas-fired plants. Nuclear consumes approximately three times as much. The nuclear figure may seem surprisingly low in light of the public debate around nuclear water; this reflects frequent confusion between water withdrawal (which tends to be much higher) and water consumption. More research is needed on contemplated future projects including modular nuclear energy.
• One of the “cleaner” coal technologies, the integrated gasification combined cycle process, reduces a coal plant’s water consumption by half, while also reducing carbon emissions and other pollutants. However, contemplated carbon capture technologies could increase a coal plant’s water consumption by 30%-100%.
• Wind and solar photovoltaic electricity consume minimal water and are the most water efficient forms of conventional or alternative electricity production.
• The installed base of the solar thermal form of electricity generation (as opposed to photovoltaic) consumes twice as much water as coal and five times as much as gas-fired power plants.
• Natural gas produced by a technique called hydraulic fracturing is a game-changer that could alter the entire energy mix of transportation fuels and electricity generation. The main water issue here involves pollution, which is beyond the scope of this paper; however, additional research is needed on consumption, particularly in order to reflect substantial changes in the technology and its application to oil. Current data indicate that natural gas produced by hydraulic fracturing consumes seven times more water than conventional gas extraction but roughly the same amount of water as conventional oil drilling.

EPRI has just published this report, which uses the most current data to frame freshwater availability/water resource sustainability across the U.S and across all water using sectors. The report also includes several scenarios to frame how the issue may develop over the next 25 years. This is a framing study which identifies potential geographical areas of concern and explores trends and interrelationships among the water using sectors. More refined analyses are needed to evaluate alternative water management plans for specific localities. As with all analyses of this nature, there are multiple assumptions and caveats; hence, one should read the text to fully understand what these are before citing figures or tables.
2011: Bekiroglu, Sultan, and Omer Eker, The Importance of Forests in a Sustainable Supply of Drinking Water: Istanbul Example, African Journal of Agricultural Research, Vol. 6(7), pp. 1794-1801, 4 April 2011.
Istanbul has administrative, social and economic, drinking water problems. The forest areas of Istanbul are more important to drinking water than any other of the forest’s activities, because most of the drinking water dams are located in forest areas. This study is aimed at determining the differences between past and present forestry applications concerning drinking water production in Istanbul for a 600 year period.
The level of future drinking water problems in Istanbul was also estimated. Using descriptive analysis method similarities and differences between past and present forestry applications in producing drinking water were identified. Furthermore, the trend of Istanbul’s water demand and supply for the 2010 and 2030 term was also predicted with a scenario.
This study indicates that Istanbul city has historically experienced drinking water and forest resources shortages. In the past administrators were very keen to conserve forest areas and drinking water resources for the city. Various regulations to protect and improve the utilization of water resources have been created throughout the history of Istanbul. These measures today are not as effective as they once were which causes exploitation and destruction of water resources.

To date there has been limited research on integrated water resource management from a global perspective. This paper gives an overview of current and impending water problems while assessing the investment needs for integrated water management as a possible solution to projected water challenges. The analysis compares a business as usual case to a scenario in which investments improve water efficiency use across sectors to curb demand, increase innovative supply from desalination, and enhance conventional water resource management measures. Systems dynamics modeling is employed to represent the structural factors in the context of an integrated framework including cross-sectoral linkages. The analysis concludes that water sustainability is feasible, but would require investments in the range of $145 billion per year between 2011 and 2050, and timely, effective action.

Arid regions and their cities are vulnerable to future water scarcity because climate change threatens to reduce supply and rapid growth increases demand. The study of water sustainability in these regions and cities transcends concern about these topics, and includes the dynamics of water-energy relationships, tradeoffs involved in the use of irrigated landscaping for temperature control, and feedbacks between urban growth, the economy, and the environment. It requires analysis of how complex human and biophysical systems function at a range of scales and calls for new tools for risk assessment and decision support incorporating decision making under uncertainty.

Gomes, Carla, Computational Sustainability, Computational Methods for a Sustainable Environment, Economy, and Society, The Bridge, 2009.
Key issues in the development of policies for sustainable development will entail complex decisions about the management of natural resources. Making these decisions implies significant computational contributions and will require cooperation among disciplines that do not usually work together. The idea of computational sustainability represents the needed cooperation among these fields, to consider the whole system and how it can be made more sustainable. Biodiversity and species conservation, with special emphasis on marine resources, is studied as an example. Agrarian systems and pastoralism are similarly considered.
In all these cases, the demand for improved data and computational systems is in evidence. For example, large-scale sensor networks may be expected to impose increasingly heavy demands on natural resources management. One implication is the development of the Smart Grid, a composite of information and power networks that would weave together users and consumers in ways that are not now possible. The energy needed for such efforts would put natural energy resources as both something that must be managed, as well as something that is needed to make the network a reality.
The solution to this kind of systems analysis requires computational models of great sophistication, which largely do not exist today. Development of system models would go far beyond the kind of computer science now taught. Research in this field would require scientists from different fields to work together; natural resource specialists, operations researchers, mathematicians, economists, and policy analysts to name just a few. The focus would be on developing comprehensive computational models that can be used to make more sustainable decisions about natural resources and how they are used. Computational sustainability opens up fundamentally new territory for intellectual progress, with the promise of contributing unique societal benefits.

the visible manifestations of globalization are the greater international
movement of goods and services, financial capital, information, and people.
There are also technological developments, more international cultural exchanges,
increased freedom of trade in new products and services, immigration, political
changes, and ecological consequences. This study links the Maastricht
Globalization Index with Sustainability Indices to analyze whether more
globalized countries are doing better in terms of sustainable development and
its dimensions. The results seem to suggest that the process of globalization
may render world development more sustainable. The study can be found at https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0B8FZ9WSEG7a2NmUzNTY1NjEtYWRjMS00NjAwLWFiMjAtYzRjNmRjODZiNjc0&hl=en_US

The global future lies before us as a highly uncertain and contested landscape with numerous perils along the way. This study explores possible pathways to sustainability by considering four different scenarios for the twenty-first century. The analysis reveals vividly the risks of conventional development approaches and the real danger of socio-ecological descent. However, there is also Great Transition scenario-implying a civilization of enhanced human well-being and environmental resilience. This option includes a suite of strategic and value changes for getting there. A fundamental shift in the development paradigm is found to be an urgent necessity for assuring a sustainable future and a hopeful opportunity for creating a better world.

2011: A recent study on Water Sustainability in Uzbekistan is Schieder, Tina-Maria, Analysis of Water Use and Crop Allocation for the Khorezm Region in Uzbekistan Using an Integrated Hydrologic-Economic Model, Rheinische Friedrich-Wilhelms-Universitat, Bonn, Germany, 2011. This document can be found at http://hss.ulb.uni-bonn.de/2011/2493/2493.pdf
Sustainable and efficient water management is of central importance for the dominant agricultural sector, the population, and the environment of the Khorezem region. The region is situated in the lower Amu Darya river basin in the Central Asian Republic of Uzbekistan and the delta region of the Aral Sea. Deterioration of the ecology is due to vast expansion of the agricultural area, the utilization of marginal land, and very intensive production of cotton on much of the agricultural land. Supplying food for increasing population and coping with the arid climate require intensive irrigation. Current irrigation strategies are not flexible enough to cope with supply-demand problems, and the political system has promoted unsustainable water use rather than preventing it.
The focus of the study is analysis of more economical and efficient water management and crop allocation. To adequately analyze underlying conditions, an integrated water management model is used. To promote an interdisciplinary approach, hydrologic, climatologic, agronomic, institutional, and economic relationships are integrated into one coherent optimization model for the region.
Simulations with the model indicate that a modification of the regional water supply has a large influence on the total irrigation, ground water, and drainage system, as well as the soil water budget. Low water supply would cause a shift in crop allocation to less water demanding crops such as vegetables, wheat, alfalfa, and fruits. At higher water supply levels, cultivation of water-demanding rice would become more advantageous. Other results show that better distribution and irrigation systems would reduce infiltration losses. Potential changes indicate that the cotton sector could be restructured to less water-demanding crops with higher economic values. Cotton sector reform would lead to a general redistribution of acreage with compensation for losses caused by abolition of cotton subsidies. However, the abolition of subsidies implies greater risk for farmers. Water pricing could help induce environmental awareness and promote conservation.

The Marcellus Shale formation stretches from Tennessee to New York, and it is estimated that there may be enough natural gas housed in these structures to supply the United States for approximately 100 years at current consumption rates. Positive effects include possible lower energy costs, about 280,000 jobs, and millions of dollars in local revenue. The fracking process involves cracking open the shale by injecting water, sand, and chemicals at extremely high pressure. However, along with the produced gas there are risks, benefits, and implications for sustainability.
USGS DOCUMENTS: Because of the spirited dialogue surrounding this issue, a search was carried out for USGS documents that relate to the geology of the problem (see http://www.usgs.gov). A large number of highly technical documents were found, and for this message four were selected that may help to improve understanding of the issue. The documents are:

2011: Claudia Pahl-Wostl, et al: Adaptive and Integrated Management of Water Resources
This paper is available as part of a book for sale from several sources. The book is Water Resources Planning and Management, Grafton and Hussey (eds.), Cambridge University Press, www.cambridge.org, $83.26 (Amazon), 2011. It includes 35 papers on water resources.
The paper can be seen on-line, and can be viewed at:
The impacts of climate change on freshwater resources will primarily be due to changes in temperature, rising sea levels, and increased precipitation variability. Changes in precipitation, evaporation, and snowmelt will cause widespread impacts in the hydrologic cycle relating to availability and quality. Climate induced changes in land use, population, and urbanization will increase the intensity of demand and the vulnerability to extreme events.
The authors include extensive literature references to support their views, and examine tools like Integrated Water Resources Management to cope with the impacts. Managers might be assisted by dashboard-like models, that enable them to see quickly the results of their decisions on the real world. Finally, the conclusions reached are that much of the problem falls not into the technical realm, but into that of management and governance.
The Council on Environmental Quality (CEQ), Executive Office of the President, has released a draft report for comments on this subject. The report is the Draft National Action Plan: Priorities for Managing Freshwater Resources in a Changing Climate, June 2, 2011.
The report contains a number of recommendations, as follows: Government agencies and citizens should collaboratively manage freshwater resources in response to a changing climate in order to assure adequate water supplies, protect human life, health and property, and protect water quality and aquatic ecosystems. To accomplish that goal, the draft Action Plan identifies specific actions Federal agencies should take, including:
• Establish a planning process to adapt water resources management to a changing climate that includes better coordinating Federal agencies and maintaining strong engagement with state, local and tribal governments, stakeholders and the public.
• Improve the quality of water resources and climate change information available to decision-makers.
• Expand the use of water efficiency practices and technologies.
• Develop a toolbox of the most effective freshwater conservation practices to help state and local officials and facility managers identify and adopt these practices.
• Develop a pilot climate change vulnerability index for a major category of water facilities, such as drinking water systems, to help facility managers prioritize their adaptation responses.
• Develop a “one stop” internet portal for up-to-date data and information on water resources and climate change.

This report covers the concerns about risks to drinking water supplies from the hydraulic fracturing process. EPA is now undertaking studies to determine the effects. There will be Retrospective Case Studies to investigate reported instances of drinking water resource contamination or other impacts in areas where hydraulic fracturing has already occurred. Three to five sites across the US will be investigated. A report of interim research results will be completed in 2012, mostly focusing on the Retrospective Studies.
Prospective Case Studies will involve sites where hydraulic fracturing will occur after the research is initiated. Sampling will be done before, during, and after the process is carried out. Two to three sites in different regions of the US will be included. A second report in 2014 will include more information about the long-term results of the research.
The draft study plan will be submitted to the EPA Science Advisory Board for review before being finalized. Stakeholders and the public will have an opportunity to provide comments to the Board during the review.
March 2011: The Omnibus Public Lands Act (Section 9506 of Public Law 111–11, Appendix A, which incorporates the SECURE Water Act) calls for a report to Congress that describes the current scientific understanding of each impact of global climate change on freshwater resources of the United States.
This draft report identifies key actions to improve the Nation’s capacity to detect and predict changes in freshwater resources that are likely to result from a changing climate. In addition, a series of next steps for Federal agencies is provided. The ultimate goal is to help decision-makers and water resource managers by facilitating improvements in observational, data acquisition, and modeling capabilities.
The draft report is available at http://acwi.gov/Rpt.Congress3.18.11.pdf
March 2011: The Government Accountability Office (GAO) carried out a study titled Amount of Energy Needed to Supply, Use, and Treat Water is Location-Specific and Can Be Reduced by Certain Technologies and Approaches. This study can be found at http://www.gao.gov/products/GAO-11-225
Few nationwide studies have been conducted on the amount of energy needed to provide drinking water and wastewater services, and these studies do not consider all stages of the lifecycle in their analysis. The energy demands of the urban water lifecycle vary by location. Important factors include topography of the service area, the level and type of treatment provided, and the quality of the source water. Systems relying on ground water as a drinking water source generally use less energy than systems relying on surface water, because ground water usually contains fewer contaminants and therefore requires less treatment.
Installing more efficient equipment, adopting water conservation measures, and upgrading infrastructure are some approaches that can decrease energy use. Technologies to identify potential pipeline leaks throughout water systems can reduce water loss and consequent energy requirements. Barriers to more efficient operation may include the costs to retrofit plants with better equipment and competing priorities at treatment facilities, and other factors.

Osooli, Nooshin et al,
A Survey: Factors Affecting the Sustainable Water Resources Management (SWRM) in Agriculture Under Drought Conditions in Lorestan, Iran. World Applied Sciences Journal 12 (4): 476-484, 2011.
Drought is one of the climatic phenomena that would always cause some damages for human societies. Drought occurs in all climatic regimes of Iran with different intensities. Low precipitation rate has resulted in decreasing river discharge, early exploitation of wells and early aquifer loss in Lorestan Province in recent years. Therefore, it has worsened the drought crisis. The agricultural sector of the province has showed very vulnerable and its crop yield has quite decreased due to inefficient water resources management.
As its main objective, the research was conducted to study the factors affecting the sustainable water recourses management in agriculture under drought conditions in this province. This survey was conducted on a number of 220 wetland farmers and 70 experts linked to the subject and selected by Cochran Formula and cluster sampling method. The data were analyzed with Confirmatory Factor Analysis (CFA) Method and the LISREL 8.5 Software. The results indicated that all economic, technical, farming, socio-cultural and educational-extensive factors had significant effects on the sustainable management of water resources in Lorestan Province under drought conditions with 99% certainty.
Among these factors, technical
ones had the highest effect and ranking. However, socio-cultural factors showed
the lowest effect and ranking. Moreover, the amounts of the effects produced by
the indexes of these factors were based upon the amounts of standardized factor
loads and their ranking was on the same basis.
Analysis of Sustainable Water Resources Management (SWRM) in Agriculture in Khuzestan Province, Iran. African Journal of Agricultural Research, Vol. 6(1), pp 1-6, January 2011.
The purpose of this research was to analyze the supportive policies and dimensions of sustainable water resources management (SWRM) in agriculture of Khuzestan Province of Iran. The research method was a quantitative approach. Total population of experts in the study included all agricultural extension experts (n = 96) in Khuzestan Province, Iran. Based on frequency of respondents about important rate of supportive policies regarding SWRM in agriculture, 70.8% of respondents stated that encouraging farmers to use sustainable methods had very high importance. In reference to the frequency of respondents about extension system roles on realization of SWRM dimensions in agriculture, 52.8% of respondents stated that conservation of water resources had very high importance for supporting SWRM in agriculture.

This paper develops a systematic assessment of the sustainability of ecosystem services provided by rivers impacted by water storage projects. Given the conflicting preferences among stakeholders and the incomplete understanding about river ecology, managing water resources sustainably is a difficult problem. To address this problem, the methods of multi-criteria analysis and graph analysis are applied, in accordance with integrated water resource management, to assess the potential of investing in water storage projects and explore sustainable solutions through the construction of an ecosystem services index.
Mehan, Tracy: Water Management in the Collaborative Mode, WE&T, Feb. 2011, Vol. 23, No. 2. http://www.wef.org/publications/page_wet.aspx?id=9331&page=ca§ion=Viewpoint
In this article the author reviews the foundations of cooperative decision making over time, with examples like the work on Governing the Commons. This theory has led to practical application in various parts of the nation, that involve both government and non-government organizations that have stakes in water problems. Some of the examples are reminiscent of how alternative dispute resolution (ADR) is used to achieve solutions that are not traditional, and where the balance of power is such that extended gridlock could occur if solutions are not found that are acceptable to many stakeholders. Solutions of this kind are an important part of sustainable water resources management.
January 2011, National Academy of Science: A Review of the Proposed Revisions to the Federal Principles and Guidelines Water Resources Planning Document
Since it was issued in 1983, the federal document Economic and Environmental Principles and Guidelines for Water and Related Land Resources Implementation Studies (the P&G) has guided water resources project planning for four federal agencies. Since the early 1980s, however, there have been many changes in the national water resources planning landscape. In light of these developments, many groups -- including committees of the National Research Council -- have recommended that the P&G be reviewed and modernized. In 2007 the U.S. Congress directed the Secretary of the Army to revise the P&G. Congress also directed the Secretary to consult with other entities, including the National Academy of Sciences. The Council on Environmental Quality (CEQ) released its "Proposed National Objectives, Principles and Standards for Water and Related Resources Implementation Studies" in December, 2009. The present report from the National Research Council constitutes a review of the 2009 document issued by the CEQ.
study Examining Water Reuse
Implementation Challenges in Texas: Identification of Education Deficits,
2010-2011, has been published by Baylor University. The study can be found
of Texas faces unique water resource challenges in the coming decades,
highlighted by an
increasing gap between water supply and demand associated with a projected
doubling of the State’s
population over the next 40 years. Interannual climate variability further
stresses efficient water
management in a State with a dramatic west-to-east rainfall gradient,
projections of prolonged
droughts, and corresponding shifts in reliance on groundwater to surface water supplies for potable source water.
Water reuse (beneficial potable and nonpotable uses of treated wastewater) is recognized as an important approach to increase water use efficiency and diversify water resource management portfolios. However, current projections in the current Texas Water Plan indicate that water reuse will represent only 7.5% of total water demand in 2050. Thus, this project investigated why potable water reuse practices have not been more widely employed in Texas. An initial conceptual model employing a shifting the burden archetype identified infrastructure and research funding, risk communication, and reuse outreach and education as leveraging points to facilitate change.
Findings from this study identify the critical need to develop and increase water reuse, environmental health and risk education at the undergraduate level as intervention strategies to facilitate increased implementation of potable reuse practices in the Texas. Accredited undergraduate programs in environmental health science appear poised to support this activity.
National Report, Responding to National Water Resources Challenges, Building Strong Collaborative Relationships for a Sustainable Water Resources Future, U.S. Army Corps of Engineers, Civil Works Directorate, August 2010.
As important as water is to life, livelihood, and leisure, water is a resource that is often taken for granted until too much of it appears or too little is available to satisfy basic societal needs. Managing water resources as a collaborative endeavor is becoming increasingly crucial as society faces demographic, economic, institutional and climate changes manifesting across the U.S. and around the globe. These changes portend a different understanding of the risks associated with the occurrence, location, intensity and impacts of extreme events—including floods and droughts.
changes will inevitably aggravate the competition for water in already stressed
regions or emanating
from population shifts to arid and semi-arid regions, and along our lakes,
rivers and coastlines.
Change will also affect water quality by stimulating sea level variations and,
from different patterns in the movement of sediments, lead to intrusion of
chemicals, other contaminants, and invasive species into water bodies and
related land resources. Such change will accelerate the loss of wetlands and
sensitive habitats, threaten species and reduce ecosystem services. The
resulting challenges facing the Federal government, the states, and interstate
and local governments in our management—our collective stewardship—of public
water resources come into focus as a shared responsibility for which
collaboration is an imperative, not an elective choice.
Water resource planning to address these contemporary needs involves envisioning, formulating and assessing solutions against a backdrop of complex, but sometimes limited, scientific information which is not always completely understood. Planning processes are often seen as fragmented and expensive, while at the same time challenged to accommodate diverse stakeholder perspectives without being tinged with political realities. Although such planning is typically iterative by nature, its efforts are all too often limited in perspective and scope, stymied by constrained funding, and subsumed by higher priorities.
deliberate, comprehensive planning is needed—intergovernmental by design—and
founded on an appreciation of the interconnectivity among and between natural
systems and human activities. More collaborative planning, both transparent and
inclusive, embracing the systems perspective of watersheds, river basins,
estuaries and coastal reaches is needed to realize the promise of concerted integrated
water resources management.
The water challenges facing the Nation are compelling and the needs are great. Resolving water issues successfully will take time, funding and commitment by decision makers and stakeholders at all levels of government. To succeed we must act with a sense of urgency to improve the management of critical water resources—especially in an era where the variety of changes threatens the sustainability of all natural resources. The time to act is now.
initiative represents a dialogue exploring the perspectives of the states,
interstate, and stakeholder perspectives on water resources planning and
challenges throughout the Nation. The U.S. Army Corps of Engineers was motivated
to further this dialogue because we seek to continue to move our own Civil Works
program towards a paradigm based on collaboration, sustainability and the
embrace of integrated water resources management—and we have concluded that
success cannot be achieved alone—a sustainable water resources future can only
be realized through a true intergovernmental partnership.
One desired outcome almost universally expressed by participants in this dialogue is to better articulate the roles and align the objectives across disparate water agencies, stakeholders, interests, sectors and all levels of government; however, with full recognition of the primacy of state water rights and responsibilities.
This report represents only the first phase of a journey ultimately aimed at improving water management through more effective collaboration between state, interstate and Federal water resources agencies. The document attempts to summarize the input from the diverse range of Federal, state, interstate, tribal, and nongovernment representatives who gave of their time and energy to join together and lay the groundwork towards a sustainable water future. It provides a synthesis of the issues and themes voiced during the dialogue, along with some general recommendations and suggested actions (next steps) for advancing integrated water resources management (IWRM).

Many thanks to the Deputy Chief, Research and Development, US Forest Service, for sending along this new report.
The aim of the report is to enhance and inform public dialogue about forest sustainability in the US and beyond. It contains information on the social, economic, and ecological dimensions of forest sustainability. Current forest conditions on the nation’s private and public forests are described using a set of seven criteria and 64 indicators. Recent activities promoting sustainable forests at the national, regional, and local levels are also highlighted.
Tsakiris, G., et al, Proactive Management of Water Systems to Face Drought and Water Scarcity in Islands and Coastal Areas of the Mediterranean (PRODIM), National Technical University of Athens, 2010.
Most of the islands and coastal zones of the Mediterranean suffer from droughts and water shortages which cause heavy impacts on economies, societies and the environment at local or regional scales. The PRODIM project aimed at producing rational, comprehensive, easy to use and applicable methods for assessing drought severity. Models of preparedness plans were devised, ready to be customized according to local or regional natural and socio-economic conditions.
Guidelines for facing water shortages and road maps for effective participation of stakeholders, administration officers, institutions and the public in decision making, were formulated. Simplification of the multiple character of droughts (severity, areal extent, duration, etc.) led to a uni-dimensional approach, which can be easily understood and implemented by people of different backgrounds and disciplines. The methodology was applied and refined through case studies carried out in Greece, Italy, Cyprus and Malta.
This general description of the project should help those faced with design of management plans for regions that have similar challenges.
Farrell, David et al, Drought Early Warning and Risk Reduction: A Case Study of the Caribbean Drought of 2009-2010, Global Assessment Report on Disaster Risk Reduction, 2010.
Hydrometeorological disasters are the most frequently occurring disasters in the Caribbean. Many of the Small Island Developing States (SIDS) in the Caribbean, as well as the lowlying coastal regions of South and Central America, are particularly vulnerable to hydrometeorological and climate hazards due to their geology, topography, significant coastal urbanization, small climate sensitive economies and lack of significant economic diversity.
As a result, reducing their vulnerability to climate and hydrometeorological hazards is critical if many of these states are to increase or sustain their current level of socio-economic development into the future. Drought represents one of the most frequently occurring climate hazards in the Caribbean with recent droughts resulting in economic losses and national anxiety for many Caribbean SIDS. While droughts are a frequent occurrence in the region, the region’s adaptation to such events is quite poor. This paper illustrates the impacts of the most recent drought in the Caribbean through island specific examples. The examples show the sensitivity of key economic sectors (in particular water and agriculture) to drought and the low resilience of the region to drought.
This low resilience is due to limited national and regional capacity in key areas, systemic problems within countries that limit information sharing between key stakeholder institutions, inadequate policies, and limited finances to implement and sustain key activities. We conclude that unless more is done to increase the region's resilience to drought, the region will be challenged to sustain and enhance its socioeconomic development under range of future climates and increasing climate variability currently being forecast.
Areas where more needs to be done include (i) enhancing the quality, delivery and targeting of climate services to national and regional stakeholders, (ii) increasing data sharing, enhancing collaborations between national, regional and international stakeholders, (iii) policy reform with respect to Integrated Water Resources Management (IWRM), and (iv) public education. We conclude that if significant improvements are not made with respect to adaptation to drought, many Caribbean SIDS will find it difficult to adapt to future regional climates which are expected to be marked by on average longer drier conditions than present.
Water for Business, Initiatives Guiding Sustainable Water Management in the Private Sector, World Business Council for Sustainable Development, International Union for Conservation of Nature, Version 2, March 2010.
Every business depends and impacts on water resources. Some use it to process raw materials and manufacture goods. Some use it for cooling and cleaning. For others, it is a central ingredient in the goods they produce, or it is required to consume the product they sell.
The future of business depends on the sustainability of water resources, which are increasingly under pressure. Globally, per capita availability of freshwater is steadily decreasing and the trend will inevitably continue as the world’s population swells towards 9 billion, emerging economies increase consumption levels and climate change unfolds.
For the global economy to carry on expanding at the same pace without improvements in efficiency, worldwide annual water consumption would have to rise from 4,500 km3 today to 6,900 km3 in 2030 – that is 40% above current accessible, reliable supply.
Some of the key questions facing business today include: How might water availability and allocations restrict my company’s supply chain? What effects will the lack of water security have on my markets? Will my customers have enough water to enable them to use my products or services? Can I justify my water consumption with regard to other users, including environmental requirements? And also: Can I boost my revenues by providing solutions? The global business community increasingly recognizes the water challenge, but to respond effectively it needs guidance, tools, standards and schemes to enable change to more sustainable practices. Since 2006, many new initiatives and concepts have emerged to address this need, driven by business leaders in the field, civil society and governments. Most are global with multistakeholder representation; but some are also addressing more and more the specificities of water usage for a particular sector (the beverage industry and the mining sector for example). Water risks are increasingly capturing the attention of the capital markets as reflected by the recent launch of the CDP Water Disclosure.
The WBCSD and IUCN have joined forces to produce this guide to help business better understand and meet the water challenge. The WBCSD has been actively working on water issues for over 10 years and has helped move water up everybody’s business agenda. The WBCSD recently produced a set of tools intended to help member companies integrate water issues.
Purpose and scope
The world is in desperate need of tools for sustainable water management. Some exist and are widely used, others are still under development. This guide is aimed at helping business identify which initiatives and approaches will most suit their needs, and to help developers of schemes understand opportunities for increasing impact through consensus building and joint action.
The key objectives of this document are to:
• Provide a structured overview of major initiatives to improve understanding of “who is doing what”;
• Help build a common language for business on water sustainability;
• Support the identification of risks and opportunities, gaps and complementarities;
• Demonstrate leadership and facilitate business engagement in relevant initiatives.
Berger, Markus and Matthias Finkbeiner, Water Footprinting: How to Address Water Use in Life Cycle Assessment?, Sustainability, 2010, 2, 919-944, ISSN 2071-1050 http://www.mdpi.com/2071-1050/2/4/919/pdf
As freshwater is a vital yet often scarce resource, the life cycle assessment community has put great efforts in method development to properly address water use. The International Organization for Standardization has recently even launched a project aiming at creating an international standard for “water footprinting”. This paper provides an overview of a broad range of methods developed to enable accounting and impact assessment of water use. The critical review revealed that methodological scopes differ regarding types of water use accounted for, inclusion of local water scarcity, as well as differentiation between watercourses and quality aspects. As the application of the most advanced methods requires high resolution inventory data, the trade-off between “precision” and “applicability” needs to be addressed in future studies and in the new international standard.
Mathews, Kevin, The Water Imperative: Blue is the New Green, Sustainability Summit, Arlington, Virginia, December 7, 2010.
This presentation covers the efforts of Nestle’ Waters North America (NWNA) to carry out a program of water sustainability, showing how their products impact water resources and what actions the company is taking. To frame the issue, the point is made that most of the world’s population will experience water stress by 2025. Climate change is expected to cause major changes, leading to increased competition among water users. Because of increasing rates of consumption, and the fact that there is no substitute for it, water may become the “oil” of the 21st century.
In 2007, Nestle’ and five other world business leaders launched the CEO Water Mandate. The UN Global Compact Project was designed to help companies reduce their water use throughout their supply chains. Over the past 10 years, Nestle’ has reduced its water usage ratio by 28 percent. Industrial methods include irrigation water reuse, filler flush timers, reuse of air conditioner condensate, and cleaning in place. The NWNA approach considers the whole supply chain from raw material to end of life disposal of the product.
The Beverage Industry Environmental Roundtable (BIER) is a partnership of leading beverage companies including Nestle’, Coca Cola, Bacardi, Pepsico, Beam, Coors, and others, to quantify and improve water use and efficiency, share best practices, reduce greenhouse gas emissions, and quantify water footprinting. Other partnerships include water education, sustainable land and water use (with the Nature Conservancy), and a sustainable agriculture initiative. Case studies with companies like Anheuser-Busch have shown positive results.
Kant, Krishna, NSF Briefing on Sustainability Programs, Presentation at INFOCOM 2010, March 17, 2010.
NSF programs cover a variety of topics that relate to sustainability, and funding supports them to various degrees. Funding through 2009 shows a steady increase, and further funding is sought for succeeding years. A 2009 study resulted in findings about how sustainability is important for the whole economy. There are a number of general topics for which NSF has allocated sustainability funding. These include Computing, Environment, Climate Research, Earth System Modeling, Biodiversity, Water Sustainability and Climate, Ocean Acidification, Climate Change Education, Science, Education, and Engineering, and others (given in a table). Contacts are given for more information about these topics.
The USGS has published the report Maupin, M.A., and Arnold, T.L., 2010, Estimates for self-supplied domestic withdrawals and population served for selected principal aquifers, calendar year 2005: U.S. Geological Survey Open-File Report 2010-1223, 10 p. This report can be found at http://pubs.usgs.gov/of/2010/1223/
The National Water-Quality Assessment Program of the U.S. Geological Survey has groundwater studies that focus on water-quality conditions in principal aquifers of the United States. The Program specifically focuses on aquifers that are important to public supply, domestic, and other major uses.
Estimates for self-supplied domestic withdrawals and the population served for 20 aquifers in the United States for calendar year 2005 are provided in this report. These estimates are based on county-level data for self-supplied domestic groundwater withdrawals and the population served by those withdrawals, as compiled by the National Water Use Information Program, for areas within the extent of the 20 aquifers.
In 2005, the total groundwater withdrawals for self-supplied domestic use from the 20 aquifers represented about 63 percent of the total self-supplied domestic groundwater withdrawals in the United States; the population served by the withdrawals represented about 61 percent of the total self-supplied domestic population in the United States.
The December 2010, Vol. 2, No. 1 Journal of Management and Public Policy is a special issue on water. This biannual peer reviewed international journal is published in June and December every year by the Management Development Research Foundation, New Delhi, India. The online edition of the journal is available at http://www.jmpp.in as an open access journal. The December issue is the “current issue.” You can find earlier issues by going to the archive list on the left-hand side of the home page. Here is a brief description of the contents:
Adam Smith in his famous book ‘An Inquiry into the Nature and Causes of the Wealth of Nations’ has pronounced the famous diamond-water paradox, where he argues that water is priceless, even compared to diamond because water is imperative for life. The diamond-water paradox proves that scarcity makes diamond costly. Growing urbanization and industrialization has made water a costly product. Trans-national corporations are catching the market for safe drinking water as well as other uses of water. Global evidence proves that market for water is costly and risky if it is not properly regulated by government. Public policy for the distribution of water is very important at a time when neither the public water bodies nor the private water bodies are sensitive to the use and misuse of water. There are certain loopholes in the system, which need to be taken care of properly when we have global task like providing safe drinking water to one billion people on this earth as a part of the Millennium Development Goal (MDG). The current issue of Journal of Management & Public Policy presents a critical analysis of public policy on water. This issue is an important collection because the mixture of developed and developing countries’ experiences makes us aware about what and how water policy should be framed.
Clear Gold: Water As a Strategic Resource in the Middle East, Center for Strategic and International Studies, Washington DC, December 2010.
Study description: http://www.csis.org/publication/clear-gold
Water is a fundamental part of the social contract in Middle Eastern countries. Along with subsidized food and fuel, governments provide cheap or even free water in order to ensure the consent of the governed. But when subsidized commodities have been cut in the Middle East, instability has often followed. Water’s own role in prompting unrest has so far been relatively limited, but that record is unlikely to hold. Water has no substitutes, and while cheap in its natural state, water is expensive to process and transport. Future water scarcity will be much more permanent than past shortages, and the techniques governments have used in responding to past disturbances may not be enough.

A report has been located from the Global Water System Project, specifically the proceedings The Global Dimensions of Change in River Basins, University Club, Bonn, Germany, Dec. 6-8, 2010. The report can be found at:
This proceedings contains 20 papers from various parts of the world. Some selected subjects include:
Impact of global change on large river basins, River flow projections in a changing climate, Impacts of national and international actors on river basin management, Effect of changing anthropogenic and climate conditions on BOD loading and water quality, Water resources planning and management regions: new insights for defining regions.
The Sustainable Society Foundation has launched the new update of the Sustainable Society Index, SSI-2010. This is already the third edition of the SSI, after SSI-2006 and SSI-2008. The SSI, based on 24 indicators, comprises the three wellbeing dimensions of sustainability in its broad sense: Human, Environmental and Economic Wellbeing. The SSI has been calculated, like the previous editions, for 151 countries.
Since this is the third edition, SSI can make comparisons over time, however cautiously. It shows that the world at large has grown in wealth, but that this increase has hardly been used for progress on the way towards sustainability. The overall index slightly increased in the past four years from 5.8 to 5.9.

Alteration of Streamflow Magnitudes and Potential Ecological Consequences: A Multiregional Assessment, Ecological Society of America, Front Ecol Environ 2010; doi: 10.1890/100053,
Most River Flows across the U.S. are Altered by Land and Water Management, Leading to Ecological Degradation. This USGS assessment provides the most geographically extensive analysis to date of streamflow alteration. Findings show that the amount of water flowing in streams and rivers has been significantly altered from land and water management in nearly 90 percent of waters that were assessed in the nationwide USGS study. Flow alterations are a primary contributor to degraded river ecosystems and loss of native species whose survival and reproduction are tightly linked to specific flow conditions. These consequences can also affect water quality, recreational opportunities and the maintenance of sport fish populations. Flows are altered by a variety of land- and water-management activities, including reservoirs, diversions, subsurface tile drains, groundwater withdrawals, wastewater inputs, and impervious surfaces, such as parking lots, sidewalks and roads. The severity and type of stream flow alteration varies among regions, due to natural landscape features, land practices, degree of development, and water demand. Differences are especially large between arid and wet climates. In wet climates, watershed management is often focused on flood control, which can result in lower maximum flows and higher minimum flows. Extremely low flows are the greatest concern in arid climates, in large part due to groundwater withdrawals and high water use for irrigation.
In September 2010, the New Zealand Land and Water Forum issued Report of the Land and Water Forum, A Fresh Start for Freshwater. This document is available on the Land and Water Forum website at http://www.landandwater.org.nz/land_and_water_forum_report.pdf.
This report covers a variety of land and water problems in New Zealand, which may be similar to those faced by others. Although some water bodies have good quality, problems are mounting because of the failure to set limits, for example on nutrients. This has implications for institutional arrangements at different government levels. The growing problem of scarcity should be managed better, so that water is allocated on a rational basis. A permit system is in place, but changes are needed to make it easier to transfer permits between users. Rural water infrastructure should be improved so as to increase the availability of water, and promote economic development. Across the board improvement in water science is needed, including research and application to data collection, storage, and utilization. In urban areas, stakeholders should be engaged to develop comprehensive water and wastewater management plans. Because of the major impact of floods, policies should be developed to connect land management with impacts on the river systems. A series of recommendations is included that are intended to accomplish the needed changes in land and water management.
We Finance Urban Water Challenges To Come: Do We Need A New Business Model?World
Water Congress and Exhibition, International Water Association, Montreal, Sept.
article points out that the traditional approach of simply providing the
engineered facilities for water is no longer adequate to present needs within a
watershed. Multiple requirements are now the norm. The economics of water
pricing affect demand, and thereby the behavior of water users. Recent examples
include the development of price management strategies that attempt to balance
water use by differential pricing. In addition, future water sources may become
smaller and more decentralized, and rely on a mixture of nontraditional water
sources within a watershed. Attempts are also underway to include the non-human
needs of the ecology in the management plan, and to develop ways to distinguish
among the differing needs for water of different quality. This complex mixture
of elements then becomes the basis for sustainable water management in a given
The natural watershed and the local hydrologic cycle then become more important to developing a viable approach. Some examples of the resulting changes include the use of green roofs, water gardens, and expanded use of trees and plants, rather than only relying on engineered solutions. The resulting smaller systems have implications for local water pricing, financing, and how benefits are realized for users in the watershed. This is far from business as usual, and requires a new role for government in fostering this decentralized approach. Specifically, integrating the full value of water into management practices is a significant departure from underpriced supplies that many now enjoy. Reaching this new goal will challenge all aspects of water supply and demand economics in the nation.

Water Resources Sustainability, AWRA Watershed Update, Jan.-June 2010, Vol. 8, No. 1,
The article covers definitions of water resources sustainability, for example as seen by the 1983 Brundtland Commission, and defined by the Daly Rules for Sustainability. One important point is the comparison between the rate of water use and the rate at which water can be replenished. A systems analysis approach is also included, which discusses how water sustainability is affected by long duration, the use rate, moderate solutions to problems, and the flexibility of solutions.
Peak Water Limits to Freshwater Withdrawal and Use, National Academy of Sciences, June 22, 2010, Vol. 107, No. 25, 11155-11162,
Observers may be familiar with the concept of “peak oil,” in which a nonrenewable resource is assumed to have passed its peak of production. Some descriptions claim that the world is now on the downward trend because less oil remains to be recovered. This paper applies the concept to water, which is generally considered a renewable resource.
Three kinds of peak water are described. Peak renewable water occurs where flow constraints limit total water availability over time. Peak nonrenewable water is observable in groundwater systems where production rates substantially exceed natural recharge rates, and where overpumping or contamination leads to a peak of production followed by a decline. Peak ecological water is defined as the point beyond which the total costs of ecological disruptions and damages exceed the total value provided by human use of the water.
Elevated nutrients in the Nation’s Streams and Groundwater—A Continuing Issue, National Water Quality Assessment Program, Circular 1350, USGS. http://water.usgs.gov/nawqa/nutrients/pubs/circ1350/
The information describes nutrient concentrations in the Nation's water resources, key sources of nutrients, factors affecting nutrient concentrations, potential effects on humans and aquatic life, and changes in concentrations since the early 1990s. Implications of the findings touch on many environmental issues, including those related to (1) developing nutrient criteria for surface water bodies, (2) reducing nutrients to receiving waters, (3) setting realistic expectations for water-quality improvements following nutrient reduction strategies, and (4) managing elevated nutrients in drinking water from surface-water intakes and wells.
Wastewater Infrastructure Financing: Stakeholder Views on a National Infrastructure Bank and Public-Private Partnerships, General Accountability Office, GAO-10-728, June 2010.
One important aspect of water sustainability is maintaining water quality. Communities will need hundreds of billions of dollars in coming years to construct and upgrade wastewater infrastructure. For this reason, the General Accountability Office (GAO) was asked to prepare a short report to ascertain stakeholders views on issues of financing, especially how public and private options could work together.
This report may well serve as the basis for future policy making, as the nation attempts to cope with this important water resources problem.

Water Dependency of Energy Production and Power Generation Systems, VWRRC Special Report No. SR46-2009, Virginia Water Resources Research Center, Virginia Polytechnic Institute and State University, Blacksburg, Virginia, July 2009.
Water and energy systems constitute the foundation for modern infrastructures around the world. In the U.S., energy and power generation systems are major users of freshwater resources. Energy production systems considered in this study include primary fuel sources like coal, natural gas, and petroleum, biofuels, and synthetic fuels. Power generation technologies considered include hydroelectric, fossil fuel thermoelectric, nuclear, geothermal, solar thermoelectric, and hydrogen. Water use efficiency of various energy/power technologies is expressed in gallons of water per BTU generated.
Results of the study show that natural gas is the most water efficient energy source, while biofuels are the least efficient. Synthetic fuel production processes are also water efficient, but these technologies mostly depend on hydrocarbon feedstock such as coal and natural gas. In terms of power generation, hydroelectric power is the most water efficient, while nuclear power is the least efficient.
Water Consumption in the Production of Ethanol and Petroleum Gasoline, Engineering Management (2009) 44:981-997, DOI 10.1007/s00267-009-9370-0
Water consumption was analyzed for a number of sources, such as ethanol, conventional fuel feedstocks, oil sands, etc. It appears that water consumption varies not only with region, but also according to the technologies employed, and recovery processes. Crop irrigation is the most important factor in the production of corn ethanol. Nearly 70 percent of US corn used for ethanol is produced in regions where 10-17 liters of water are consumed to produce one liter of ethanol. Water requirements for switchgrass ethanol production vary from 1.9 to 9.8 liters of water per liter of ethanol produced. For most gasoline produced from conventional sources, the water consumed is 2.8 to 6.6 liters for each liter of gasoline. For most of the oil from Canadian oil sands, about 5.2 liters of water are consumed for each liter of gasoline produced. The differences in water consumption emphasize the need for water management plans as part of energy production.

The future adequacy of freshwater resources is difficult to assess, owing to a complex and rapidly changing geography of water supply and use. Numerical experiments combining climate model outputs, water budgets, and socioeconomic information along digitized river networks demonstrate that (i) a large proportion of the world’s population is currently experiencing water stress and (ii) rising water demands greatly outweigh greenhouse warming in defining the state of global water systems to 2025. Consideration of direct human impacts on global water supply remains a poorly articulated but potentially important facet of the larger global change question.

An Integrated Indicator Based on Basin Hydrology, Environment, Life, and Policy: The Watershed Sustainability Index
Water Resources Management (2007) Vol.21, No.5, 883-895, DOI: 10.1007/s11269-006-9107-2
This study considers Hydrology, Environment, Life, and water resources Policy (HELP) as the most important elements in the watershed, and combines them with a pressure-state-response approach to develop an overall watershed sustainability index. The study recognizes the availability of good data as a critical requirement for carrying out such studies. Within each of the major categories (e.g., hydrology) a number of indicators are used to develop numerical ratings. The overall watershed sustainability index is a linear sum of the components. The authors apply the method to a UNESCO watershed in Brazil, as an example.

Bayarsaihan, T. and D. McKinney (eds.), Past Experience and Future Challenges, Cooperation in Shared Water Resources in Central Asia, Almaty, Kazakhstan, Sept. 26-28, 2002.
Water and environmental management problems in Central Asia first gained international notice as a result of the ecological crisis brought on by the shrinking of the Aral Sea. The catchments of the Amu Darya and Syr Darya rivers, which both exit to the sea, together form the Aral Sea basin. From 1960 to 1990, the Aral Sea’s area was halved when inflows were diverted to support cotton and rice production in downstream deserts. An ecological disaster resulted as a vibrant fishery was destroyed, surrounding ecosystems devastated, and the health and livelihood of a million people irrevocably damaged.
challenge of regional water management for these semi-arid lands is no less acute
today. Attention has now turned primarily to the need for balance between upstream
hydropower and downstream irrigation interests—even as steps continue to address economic and social hardships facing those
still living around the Aral Sea.
Gleick, Peter, Water in Crisis: Paths to Sustainable Water Use, Ecological Applications, 8(3), Ecological Society of America, 1998.
A wide range of ecological and human crises result from inadequate access to, and the inappropriate management of, freshwater resources. These include destruction of aquatic ecosystems and extinction of species, millions of deaths from water-related illnesses, and a growing risk of regional and international conflicts over scarce, shared water supplies. As human populations continue to grow, these problems are likely to become more frequent and serious. New approaches to long-term water planning and management that incorporate principles of sustainability and equity are required and are now being explored by national and international water experts and organizations. Seven ‘‘sustainability criteria’’ are discussed here, as part of an effort to reshape long-term water planning and management. Among these principles are guaranteed access to a basic amount of water necessary to maintain human health and to sustain ecosystems, basic protections for the renewability of water resources, and institutional recommendations for planning, management, and conflict resolution. ‘‘Backcasting’’ a positive future vision of the world’s water resources as a tool for developing rational policies and approaches for reducing water related problems is also discussed in the context of the Comprehensive Freshwater Assessment prepared for the United Nations General Assembly in 1997.
