Groundwater recharge measures to mitigate climate change impact
Ground water recharge measures to mitigate climate change impact
Over extraction of ground water has its impact on climate change and vice versa too. Year after year since the second half of the last century, the farmers in India are digging deeper and deeper to get water for farming. This is unmatched with the efforts to recharge the same ground water. Diminishing surface water storage facilities add to the woes. In such a situation it is worthwhile to examine (i) whether it is possible to recharge the ground water using the runoff water during rains (ii) whether the existing dry deep borewells can be used to recharge (iii)whether there has to different kinds of recharge structures to suit the soil condition and (iv) how long it would take to realize the result of such recharge by the water users? This is proposed as a pilot project in a selected couple of villages facing acute shortage for ground water and lack facilities for surface water storage.
The activities proposed are:
(i) identify ground water over exploited villages
(ii) study the terrain along with technical experts and get technical suggestions on the proposed plan
(iii) locate the dried borewells by working along with the community and educate the community about the proposed plan
(v) with the participation of the community, make necessary structures to recharge water through the boreholes.
This exercise should help recharge the ground water resource for the community and enable water security for life and livelihood.
If this pilot project succeed further scaling up with the involvement of the community can be planned, and will give evidence for formulating policies in this regard.
