| 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... |

| This paper investigates the impact of the dissemination of modern irrigation systems, i.e. private wells with pumps, on the livelihood not only among the farmers who have access to wells but also among the farmers who have no access to wells and thus rely solely on traditional irrigation systems called tank irrigation systems. The analysis is based on a village and household data set collected in Tamil Nadu, India where tank irrigation systems have been managed collectively for rice cultivation. Our statistical analyses predict that once declines in collective management occur due to the dissemination of private wells, the rice yield and income of the no-well-access farmers alone will decrease, resulting in increased poverty among them. Our analyses also... |

| The micro irrigation in general and drip irrigation in particular has received considerable attention from policy makers, researchers, economists etc. for its perceived ability to contribute significantly to groundwater resources development, agricultural productivity, economic growth, and environmental sustainability. In this paper, the impact of drip irrigation has been studied on farming system in terms of cropping pattern, resources use and yield. The drip method of irrigation has been found to have a significant impact on resources saving, cost of cultivation, yield of crops and farm profitability. Hence, the policy should be focused on promotion of drip irrigation in those regions where scarcity of water and labour is alarming and where shift towards... |

| Watershed programmes in India are contributing to water resources development, agricultural production and ecological balance. Conventional methods to value them using financial measures attempt to quantify the impacts of watershed development in an isolated manner. In order to evaluate the impacts of watershed programmes in a holistic manner, the Economic Surplus (ES) approach has been applied using the data from a cluster of 10 watersheds in the Coimbatore district of Tamil Nadu. The distributional effects of watershed programmes are also captured through the ES method. Hence, possibilities of using this methodology in the future watershed evaluation programmes could be examined. The study has suggested that people’s participation, involvement of... |

| The study has revealed that over-exploitation of groundwater has effected drastic changes in energy input-use and energy output produced across the regions in Coimbatore district and the Tamil Nadu state. Energy equivalent values have been used for various direct sources of energy (human, animal and mechanical power), indirect sources (fertilizers, pesticides, manures), commercial, non-commercial, renewable and non-renewable energy sources to analyse the economics of energy usage in the agricultural production process in the two different groundwater development regions of the Coimbatore district. Energy inputs usage has been found very high in groundwater less-exploited area of Perur in paddy and cotton crops. For the coconut crop, Palladam block has... |
