Résumé
Water scarcity due to recurrent low, erratic rainfall is common in Saurashtra region of Gujarat. During mid-eighties, there was a spell of three consecutive years of low rainfall-about one-third of the annual average. Faced with severe livelihood challenge, some farmers of Rajkot district, Saurashtra region, diverted the small overflows from their farmlands almost as a hunch into their dug wells. These farmers got some crop yield compared to almost no yield of others. This encouraged many other farmers to join the dug well recharging activity. Over the years, the dug well recharging activity expanded to include many other types of water harvesting techniques such as check dams, deepening of old ponds and tanks, construction of new structures, farm bunds, small barriers with pipe outlets at water flow exit areas of farms, and storm water drain training. Farmers attributed their enhanced agriculture and livestock income to increased water availability, which resulted in, among other things, reduction in migration. There have been anecdotal studies, and at best back-of-envelope estimations of how much water had recharged into the ground, that supported agriculture. However, there has been no longitudinal study to identify how the innocuous recharge movement has converted into a social movement around water. This study is concerned with : (i) estimation of groundwater recharge at village/gram panchayat level ; (ii) computing household income change ; (iii) finding evidences to connect enhanced agriculture income and enhanced recharge by farmers with changes in the cropping intensity, pumping hours, shifts in agrarian landuse pattern (from unirrigated to irrigated land categories, and from fallows to unirrigated land), crops and cropping pattern, composition of the water extraction mechanism (WEM) and the change in composition due to availability of more water and assured 8 hours of energy due to implementation of the Jyoti Gram Yojana, investment by farmers on WEM and pipelines, seeds and fertilizers.
