The study was done under the "Strategic Analyses of India’s National River Linking Project", of the Challenge Programme on Water and Food (CPWF) to estimate the available runoff in the potential regions to mitigate the terminal drought in the dominant rainfed districts of India.
It developed a criterion and identified the dominant rainfed districts for major rainfed crops in India, made an assessment of the surplus runoff available for water harvesting and supplemental irrigation in these districts, estimated the regional water use efficiency and increase in production due to supplemental irrigation for different crops across the dominant districts and made a preliminary estimate of the economics of the proposed intervention.
The study concludes the following -
