Irrigation tanks which formed the lifeline of villages in Karnataka have deteriorated in their capacity to lend support to village economy. Several factors both historical and contemporary have been responsible for their phase-wise deterioration. The studies on tank rehabilitation and its impacts revealed that the tank rehabilitation has led to improved water storage, enhanced groundwater recharge, increased groundwater extraction, increased area under irrigation, savings in cost of fertilizers due to silt application as an organic amendment, supported livestock activities-are the tangible benefits accrued to the village community. The unequivocally supports justification for rehabilitation of tanks.
