Effect of Integrated Watershed Management Programmes on Farming in Rainfed Tracts of Tamil Nadu: An Evaluation

Abstract

As a holistic approach, watershed development activities turn out to be very effective and convenient to manage water and land resources efficiently in the rainfed areas. The present study aimed to conduct an impact assessment of watershed development programmes in Thoothukudi, Krishnagiri, Perambalur districts of Tamil Nadu by using indicators on biological, physical, social and economic aspects. In the study area, watershed development structures are found to be satisfactory and contributed for additional storage capacity, rise in water table and prolonged water availability, increasing irrigation intensity and cropping intensity which resulted from enhanced gross cropped area, crop productivity and assured access to water. More number of water harvesting structures has to be developed by engaging private investments in constructing check dams, farm ponds, percolation ponds etc. in the farms. Creating awareness about responsibilities of stakeholders in maintenance of all the assets created in the watershed areas will ensure more empowerment of the community.
