英文摘要	India is a water stressed country and projected to face an acute water crisis in the next 10 years (2020 to 2030). Due to hydrological limits, the utilizable water cannot be increased in the country. However, prudent policies are needed to judiciously use water in different sectors of the economy. It is important to account for the green (rainwater), blue (irrigation), and gray (wastewater) water flow in the economy (Mekonnen and Hoekstra Hydrology and Earth System Sciences 15:1577 1600,2011), especially in agriculture as it is the most water intensive sector in the country. The study estimates water saving from adopting alternate cropping patterns and irrigation technologies in 2030. In this context, four simulation exercises are conducted. These include shifting government procurement from staple to coarse cereals, upgrading irrigation technologies, adopting a water saving genomic variety of rice, and reducing irrigation subsidies in agriculture. The Input-Output framework is used to estimate inter-sector flows of water withdrawal and consumption in different sectors of the economy in 2030. Results reveal shifting government procurement from staple to coarse cereals saves 20.86 billion cubic meters (BCM) of blue water, however, trade-offs between green, blue, and gray water must be considered in the context of climate change. In comparison, adopting a genomic variety of rice saves 42.58 BCM of blue water. The highest blue water saving is estimated in upgrading irrigation technology, and ranges from 588.06 BCM to 1445.54 BCM. Increasing the average irrigation cost by 30 per cent saves 104.3 BCM of blue water, implying the importance of pricing incentives in water conservation in agriculture.
