| Summary: | North Gujarat is naturally endowed with one of the richest alluvial aquifers of India but its uncontrolled exploitation for irrigation has resulted in many undesirable consequences. A major hydrological opportunity for rejuvenation of the aquifer system is provided by the availability of unutilized flows from Narmada basin. It is proposed to divert this water to north Gujarat through the Narmada main canal, and use the existing canal networks and village ponds and tanks in the region to activate a decentralized recharge process. This paper examines its physical and economic feasibility. An evaluation of two recharge scenarios in north Gujarat shows that using pumped water for recharging outside the designated command area may prove to be an uneconomical proposition, unless there is substantial increase in the productivity of water. Recharge within the command would be much more economical. |
