The issue of water in South Asia seen from the perspective of human development. Report analyses the impact of water on people's ability to survive and prosper in the context of reduced supply of and increased demand for water because of growing population, increased economic activities and the effects of climate change. Economies of most South Asian countries are growing, but are the people, facing inadequate health, education and food insecurity benefitting from these economies? Can this growth be sustained without efforts to mitigate the impact of climate change? And in view of reduced water supply, can this region afford not to cooperate with its neighbours on water sharing? These are some of the issues the Report tries to analyze and address. The high quality of analytical work and the wealth of data on water and human development in South Asia collected for this Report will be valuable for policy makers and the academic community.
