Abstract
The paper analyses the consequences of groundwater overexploitation by using field level data collected from 2 well irrigated districts of Karnataka. The study result shows that the consequences arising out of groundwater overexploitation are severe in high well interference area compared to low well interference area. As a result, the overexploitation of groundwater has differential impact on different categories of the farmers in terms of cost of drilling, area irrigated per well and adoption of conservation measures. The burden of well failure is more or less equally shared by all categories of farmers but small farmers are the worst victims of resource scarcity. The study suggests maintaining inter well distance to prevent \u2018resource mining\u2019 and to educate farmers to cultivate light water crops. Institutional reforms are necessary to restore surface water bodies and facilitate aquifer recharge.
