Hello, I am Saad-ul-Haque, born in Karachi Pakistan. Currently, I am doing MS in Remote Sensing & GIS from INSTITUTE OF SPACE TECHNOLOGY, Karachi Campus. I am also working here as Research Assistant. Although I have done my Bachelors in Electronic Engineering, but my interest in GIS and Cartography has brought me into this field. Being passionate about Environmental Conservation, my future goal is to research and assess effects of Climate change using Advance Geo-Spatial Techniques. I am honored to be selected in this Fellowship program and looking forward to meet AAG team and all participants of the workshop.

ABOUT OUR RESEARCH
Drought Monitoring in Barani (Rain fed) area of Northern Pakistan
Pakistan predominantly consists of arid and semiarid regions with a diversified climate. The Barani (rainfed) Land covers the Salt Range and the Pothohar Plateau and its agriculture depends on the amount of rainfall. The mean monthly rainfall is 85 mm to 200 mm in summer and 30 to 50 mm in winter. The climate is semi-arid and sub –tropical. Moreover, the region faces direct impact of solar radiation (over 3,000 hours of sunshine/year) causing an increase in the rate of evapo-transpiration. These conditions reduce soil moisture content and affect crop yield. Pakistan’s economy is mainly dependent on agriculture (24% of total GDP).
In the past, several droughts have occurred in this area that left a drastic agricultural and socioeconomic impact.
GOALS / OBJECTIVES :
• To identify drought affected/prone areas and to assess the effects of climate change on the available water resources in the Pothohar Region of Pakistan.
• To develop a methodology to determine drought severity utilizing spatia techniques.
• To suggest possible strategies towards mitigation of drought impacts based on study outcomes.
• To recommend further studies for more effective and operationally reliable use of different vegetation indices for monitoring drought and assessing its impacts.
The objective of this project is to develop a methodology that will help in acquiring the timely information about the onset of drought, its extent, intensity, duration and impacts using state-of-the-art geospatial techniques. This information is required for drought management to better allocate limited resources during drought events and mitigation of drought-related losses. The present study will be carried out with the aim to integrate Satellite Remote Sensing (RS) and Geographical Information System (GIS) for the identification of drought vulnerable areas in barani (rain fed) areas of Pakistan. ‘Arid and extremely arid’ conditions prevail in the study area with a temporal and spatial variation in the amount of rainfall. When there is a decrease in rainfall it results in the reduction of soil moisture and hence the emergence of drought conditions. The decline in the vegetation cover is directly linked with water unavailability. Therefore, the change/decrease in vegetation cover may be alarming and considered as one of the indicators of drought condition. Other indicator that may be used for identification of drought condition is reduced soil moisture along with elevated temperatures. Satellite remote sensing data can provide continuous mapping of temporal changes in vegetation cover, soil moisture content, and land surface temperature.
This study will monitor the behavior of vegetation in the face of reduced water supply. Thus, for a developing country like Pakistan, regular monitoring of the vegetation status along with other relevant data would provide reliable methodology for drought management. Integrating satellite data with GIS techniques can lead to a cost effective drought management. It will help concerned government departments, Non-Governmental Organizations (NGOs) and others to better manage drought related issues and help vulnerable communities that are likely to be affected by future droughts.
