Water Harvesting And Watershed Management
About this eBook
PREFACE People want a right environment and infrastructure for sustained growth and better living. There needs to be a firm and time bound global commitment for boosting this emergence. In the end for a new global order, India has a crucial role to act, mainly because the country is an example of dynamism and energy. We took a commodity centered approach in our first green revolution in India in the mid-sixties in five major cereals-Rice, Wheat, Bajra, Maize and Jowar. From 1950 onwards, we made a considerable progress in modern day agriculture producing 212.05 million tons of food grains in 2003-04. We achieved the record highest yield of 212.85 million tons of food grains in 200102 in the country, although we produced the lowest food grains of 174.19 million tons in the worst-hit drought year of 2002-03, and this was the lowest production of foods in the country in last 10 years. We are still in search of more foods for meeting our increasing demand for more than a billion people in the country. We have to ensure the end of chronic hunger and malnutrition, especially the women and children by 2010. Now, there is a need for practice utilization of new farm technologies and in depth advice on ecology, economy and equity, and precision farming with holistic approach. These are all to be achieved through sustainable agriculture, spurring an Evergreen Revolution. This book Technologies for Watershed Management and Water Harvesting has dealt with the paradigm shift ensuring supply of water to every field in the rain-fed areas of drylands drought prone, arid and semi-arid regions, and this would remove hunger and poverty from these problem areas restoring ecological balance, providing green cover over deuded areas, bringing in more rains, and improving the environmental situations. It is more expected that employment, economy, ecology, export and equity five e s will be solved in the country in the very near future. The author has written this hand book on watershed development projects and water harvesting technologies as a practical reference document and has tried to highlight various topics in 13 chapters, viz. Role of watersheds in production agriculture, its activities, Implementation, approach, experience, drought management strategies, rainfed farming scenario in India. Upgrading rainfed agriculture, water harvesting concept and technologies for gainful use of water, Management of proper participation and community organizations in watershed management, role of NGOs, foreign counterparts, soil conservation techniques, application of biotechnology in agriculture, agri-business, alternative farmings on mushroom, sericulture, aquaculture, livestock animals, forage crops and grasses, vision for 2020 onwards etc.
