The overall performance of watershed development programmes has been examined in the state of Tamil Nadu. The impacts of major watershed development programmes have been outlined in terms of biophysical impacts, environmental impacts, socio-economic impacts and overall economic impacts. It is pointed out that the watershed development activities have made significant positive impacts on various biophysical aspects such as soil and water conservation, soil fertility, soil and water erosion in cropped area, changes in cropping pattern, cropping intensity, production and productivity of crops. Watershed development activities have shown significant positive impacts on water table, perenniality of water in wells, water availability for cattle and other domestic uses, etc. The overall economic impacts have been evaluated in terms of NPV, IRR and BCR. The peoples’ participation in watershed development activities has been found satisfactory but the optimal level is yet to be achieved. Training of farmers has been found effective in disseminating technical knowledge. According to the study, the future strategy should be the movement towards a balanced approach of matching the supply-driven menu with a set of demand-driven activities. Peoples’ participation, involvement of Panchayati Raj Institutions, local user groups and NGOs along side institutional support from different levels, viz. the Union Government, the state, the district and block levels should be ensured to make the programme more participatory, interactive and cost-effective. Convergence of various rural development programmes around the watershed could be ensured to promote holistic development of watersheds. For its continued success, the programme, should be economically efficient, financially viable, technically feasible and socially acceptable while ensuring equity. For, sustainable development, regular and routine monitoring of environmental parameters is important as environmental enhancement increases the credibility and acceptability of the programme.

Drip irrigation has received considerable attention from policy makers because of its significant contribution towards resource saving, enhanced agricultural productivity and environmental sustainability. This paper explores the potential benefits of drip irrigation adoption by addressing the social benefits and costs in Southern India. The study shows that adoption of drip irrigation technology has resulted in significant external and private benefits. The social benefit–cost ratio (SBCR) ranged from 4.33 to 5.19 at a 2% discount rate under different scenarios across regions. This confirms that a wide adoption of drip irrigation produces sufficient social benefits to justify the subsidization of drip irrigation. Water management policy should focus attention on the promotion of drip irrigation in regions where water and labour scarcity are critical.

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 21.15 to Rs 20.14 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.
