Résumé
The study focused to assess the economic viability of tank rehabilitation and benefits accrued to farmers after rehabilitation in the selected five community based tank systems in Haveri district of Karnataka. A sample of 25 farmers from each tank command was selected comprising of 125 sample farmers. Tabular analysis was employed to compute socio-economic features, cropping pattern, cropping intensity. Budgeting technique was employed to analyze cost and returns and financial feasibility measures were used to evaluate investment feasibility on tank rehabilitation. Out of the total investment of Rs.18.48 lakh in the tank rehabilitation highest investment was made towards desiltation (35.80%) followed by excavation of irrigation canals (21.15%), revetment (19.07%), etc. The extent of gross cropped area was increased by 21.94 per cent after rehabilitation with substantial area increase under kharif paddy, rabi sorghum and summer groundnut. The cropping intensity increased after tank rehabilitation was from 177.78 to 209.03 per cent. With increased availability of irrigation water after rehabilitation a substantial increase in the per acre crop yields of all crops in the range between 23 to 36 per cent with higher net returns which was about two and half times more than before rehabilitation thereby incremental net return from the total command area from all tanks was Rs.23.54 lakh per annum from 453.40 acres. The investment analysis has revealed a positive NPW, B:C ratio greater than unity and IRR was more than the opportunity cost of capital with a payback period of 4 to 5 years in all the five rehabilitated tanks indicated economic viability of tank rehabilitation. About 64.80 per cent of respondents opined that a moderate increase in ground water recharge after rehabilitation. The study suggested the need for increased efforts of tank rehabilitation for greater impact on the livelihood of farmers and inturn on farm economy.
