Figure 2: India – Source of irrigation

Many of the tanks, however, dry up during the summer season when more irrigation is required.

Due to non-use of these 15 percent tanks nearly 1 M-ha of Irrigation potential is lost. Another,

around 2 M-ha of potential is lost due to under utilisation of tanks in use. Loss of potential due to non use is more pronounced in Meghalaya, Rajasthan and Arunachal Pradesh (above 30%), whereas loss of potential due to under utilisation is more than 50 percent in case of Gujarat, Nagaland, Rajasthan, A&N Island and Dadar and Nagar Haveli.
