India is a large country with regional differences in per-capita water supply and demand. Attempts to describe the water situation in India at a national level are often misleading due to the tremendous diversity in the water situation across the country. This Report analyzes the spatial variation of water supply and demand across river basins in India. The study identifies basins that are water-scarce because of inadequate water availability to meet the effective demand. It also identifies issues that are important for estimating the future water demand and for the formation of policy for future water-resources development and management.

Increasing income and urbanization are triggering a rapid change in food consumption patterns in India. This report assesses India's changing food consumption patterns and their implications on future food and water demand. According to the projections made in this study, the total calorie supply would continue to increase, but the dominance of food grains in the consumption basket is likely to decrease by 2050, and the consumption of non-grain crops and animal products would increase to provide a major part of the daily calorie supply. Although the total food grain demand will decrease, the total grain demand is likely to increase with the increasing feed demand for the livestock. The implications of the changing consumption patterns are assessed through consumptive water use (CWU) under the assumptions of full or partial food self-sufficiency.

This paper seeks to identify some promising policy options which could be part of a strategic and holistic effort to address India’s future water challenges. Significant increases in agricultural water productivity would be a major factor in reducing the need for developing new water sources. Crop diversification, appropriately targeted to account for the present agricultural systems and available water resources, will increase productivity. Furthermore, much more emphasis needs to be placed on effective management of the groundwater resources through renewed efforts to enhance artificial recharge and conservation. Also, efforts should be revived to improve the existing surface irrigation systems. In particular, systems could be reconfigured to provide a more reliable water supply and allow effective community level management, where appropriate. Finally, while some of the increasing demands from domestic and industrial users will be met by the development of groundwater and reallocation of water from the agricultural sector, this will not be sufficient. Given that such conditions are emerging in states with high economic growth and relatively water scarce basins, this will require the further development of water resources. In some cases, these conditions along with the demand for reliable water for high value crops, will be part of the justification for inter-basin transfers.
