        <dc:description>This study has estimated the supply augmentation of groundwater recharge due to creation of water&#13;
harvesting structures and has assessed the cost-effectiveness of rainwater harvesting for groundwater&#13;
recharge on watershed basis in one of the sub-watersheds of the Kolar district, Peninsular India — a&#13;
typically hard-rock area. The study is based on the primary data for the year 2008-09 collected from a&#13;
sample of 90 farmers having irrigation bore-wells in the selected watershed named Thotli. The study has&#13;
indicated that the annual draft of irrigation water exceeds the annual recharge, causing a negative balance.&#13;
On an average, the returns per rupee investment have been found to be ` 1.80 on farm pond, ` 1.78 on&#13;
recharge pit and ` 1.39 on field bund. The cost incurred to impound a metre cube of water has been found&#13;
as ` 3.01 in the case of field bund, where estimated recharge benefit is 5.6 m3, ` 1.67 /m3 in the case of&#13;
recharge pit (with an estimated recharge benefit of 720 m3), and ` 1.33 /m3 in the case of farm pond (recharge&#13;
benefit of 1350 m3). The discounted cost-benefit analysis of the investment on water harvesting structures&#13;
has indicated that the investment on water harvesting structures is cost-effective and financially-viable.</dc:description>
