Groundwater depletion is experienced in several districts of Tamil Nadu state and Coimbatore district is heading in that direction. The average well failure rate is 47% for open wells and 9% for bore wells. The total cost of depletion for new wells varies from Rs 1,999 per ha to Rs 90,975 per ha. The electricity subsidy to the farmers has varied from Rs 22,621 per ha for coconut growers to Rs 25,498 per ha for banana growers as on 2004. The cost of irrigation per cubic metre (m3) is less on large farms. The average net return with free electricity varies from Rs 0.14 per m3 to Rs 1.38 per m3 and is drastically reduced when electricity is priced at an economic cost, i.e. Rs −1.15 to Rs −0.14 per m3. The shift in cropping pattern towards high value crops helped the farmers to some extent to bear the cost of externalities arising out of depletion. The social cost caused by groundwater overdraft is about Rs 554.3 million, which may increase when the well density increases further. Suggested policy options are to change the cropping pattern to less water-consuming crops, to invest in watershed development activities, to change inefficient pumpsets and to adopt well spacing norms.

<p>Civilization has been experiencing frequent changes in the climate due to global warming.</p> <div> <p>The developing nations are worst affected as they are largely dependent on the local precipitation and soil moisture for their livelihood generations. The changing climate with extended summer, change in the rainfall pattern (intensity and duration) and variations of onset and departure of seasons are directly impacting the cultivation, status of natural vegetation, surface and sub-surface water, and other natural resources in a watershed area. Among the various efforts, watershed development approach, in which intervention is more site-specific in nature and can address the local requirements, is found to be more effective at micro levels. The vulnerability of climatic changes is mainly due to water stress, degradation of natural vegetations, degradation in the health and hygiene conditions, and poor information communication technology. The present article highlights these issues, impact of watershed development project in the Himalayan region and identifying the adaptation mechanism through watershed programs. A site specific action, research methods including primary and secondary data collections, GIS, remote sensing and statistical techniques were used. The study on the Jusho Bakro micro-watershed treated by TERI under the program DROP has been found to be effective in drawing possible adapting mechanism to withstand the changing climate and its severity on the natural resources and the livelihood of the community.</p> </div> <p>&nbsp;</p>
