The paper studies groundwater use under optimal and farmer's myopic
groundwater extraction scenarios using a simple optimal control framework in
semi arid watershed of Gujarat. Implications of this extraction pattern have been
examined on the state of groundwater in terms of life of wells. The optimal control
solution suggested a three times increase in well life, with an increase of two times
in volume of groundwater extracted, increasing thereby, the net present value of
benefits from well irrigation by 2.3 times under optimal extraction regime over the
existing myopic regime of profit maximization. Sensitivity analysis done for
varying potential recharge scenario suggested that these results are stable and
marginally increase with higher potential recharge. An optimal extraction with
desired change in cropping system and groundwater allocation based on marginal
value of water has been suggested as the panacea for falling groundwater table.
