2. Impacts of changing trends in resource consumption
How pressure on resources affects the future security of places
The water–food–energy “nexus” and how its complex interactions affect:
national water security, including access to safe water
national food security, including food availability
national energy security, including energy pathways and geopolitical issues
The implications of global climate change for the water–food–energy nexus
Detailed examples of two countries with contrasting levels of resource security
The disposal and recycling of consumer items, including international flows of waste
Synthesis, evaluation and skills opportunities
How perspectives on, and priorities for, national resource security vary between places and at different scales
Objective: to gain and understanding of the complexities of 'The Nexus' and how its complex interactions affect:
national water security, including access to safe water
national food security, including food availability
national energy security, including energy pathways and geopolitical issues

CASE STUDY1: MALAWI - Examining synergies in the WFE nexus
Synergy - this is an interaction or cooperation giving rise to a whole that is greater than the simple sum of its parts.
Describe the food-water-energy linkages mentioned in Malawi.
2. Explain how a new style of cooking stove is an example of nexus thinking and will benefit the country that is facing greater water insecurity as a result of climate change..

Rising temperatures can expand sea water and cause rising sea levels to encroach on low lying fresh water supplies in Bangladesh.
Those same rising temperatures, combined with decreasing precipitation levels, can lead to drought in places like California, Sudan, Somalia, and Australia. This drought could lead to crop failures and famine.
Because these changes to water and temperature levels can impact our water and food security, that means they will also affect our energy security, since they are all linked together.
These impacts of climate change will certainly vary around the globe, based on the actual climate changes, levels of economic development, the latitude of a place, and the vulnerability of the population.
In this section, we will take a look at the impacts of climate change on resource security in the Hindu Kush
The concept of the food, water, and energy nexus is extremely relevant to Asia as the region has to feed two-thirds of the world’s population (4.14 billion people) and accounts for 59% of the planet’s water consumption.
With just 3% of the world’s land, South Asia has about one-fourth of the world’s population (1.6 billion people). Rice and wheat, the staple foods in the subregion, require huge amounts of water and energy.
Freshwater, once abundant, is under growing stress due to the increased demand for competing uses, and climate change is creating additional uncertainties.
About 20% of the population of South Asia lacks access to safe drinking water. The increase in water stress and water demand raises questions about how to ensure enough water for growing food without losing hydro- power for energy security.
About 1.3 billion people in South Asia rely on freshwater obtained directly or indirectly from the Hindu Kush Himalayan (HKH) mountain systems.
TASK: Outline why a nexus approach to resource management is important for the Hindu Kush region of South Asia and what effect climate change will have on the Nexus.

Concepts: The process of recycling creates possibilities for increased global interactions. The movement of waste can often pass from wealthier to poorer places.

An analysis of the disposal and recycling of consumer items, including international flows of waste.
Notes to add: Why Have polluting industries relocated to the developing world?
Initially due to financial considerations of cost in terms of labour
Advances in transport e.g. containerisation and telecommunications
Importantly, countries that are less developed tend to have fewer environmental controls.
Theoretically this idea is represented in the diagram of the Environmental Kuznets Curve on the right.
Until recently China imported more than 3 million tonnes of waste plastic and 15 million tonnes of paper and cardboard each year. A third of the UKs waste plastic and paper was exported to china each year.
