Cost and benefits of intermediate water storage structures: case study of diggies in Rajasthan

This paper assesses the cost and benefits of "diggies”, the intermediate water storage structures in the Indira Gandhi Nehar Pariyojana project in Rajasthan. A diggi helps provide reliable water deliveries to farms and that in turn expects to increase crop production. Our analysis shows that through better water control, farmers with diggi's have increased cropping intensity, input application and crop productivity. The net value of crop production per ha of irrigated area of farms with diggi's is 68% higher than that of farms without diggi. A cost-benefit analysis shows that diggi is a financially viable intervention for farms with size larger than 4 ha
