Abstract
There has been a growing realization for rehabilitation and restoration of
irrigation tanks with farmers’ participation. The study has presented the
costs and benefits of tank rehabilitation and financial feasibility of
investment in tank rehabilitation. The total annual income has been found
higher in the rehabilitated tanks than the non-rehabilitated tanks and
amongst the rehabilitated tanks, panchayat tanks with community well
has depicted the highest annual income. The investment analysis has
revealed the net present worth to be positive, the B-C ratio to be more than
1.5 and the internal rate of return to be more than the opportunity cost of
capital. This shows that all the three investments in tank rehabilitation are
economically viable. The study has suggested that rehabilitation work
should be undertaken in all the non-rehabilitated tanks also. Besides,
efforts should be made to provide supplemental irrigation to crops and to
improve the PWD tank management regime.
