This book provides a comprehensive presentation of the realization of improved rainfed agriculture yield in semi-arid and dry land areas. The incentive of watershed programs is to increase the return on investment with over 20% for 65% of the projects that are currently underperforming. Besides techniques to improve the livelihood of the many small-scale farmers in developing countries, it includes examples and case studies for further support. The methods discussed have recently shown to be successful and economically remunerative in India and in various African countries. Intended for professionals (investors, policy makers), researchers and (post) graduate students working on dry land and sustainable agriculture and water and natural resources management. Suited for courses in dry land agriculture, soil and water management and watershed development.

A watershed is simply the geographic area through which water ows across the land and drains into a common body of water, whether a stream, river, lake, or ocean. The watershed boundary will more or less follow the highest ridgeline around the stream channels and meet at the bottom or lowest point of the land where water ows out of the watershed, the mouth of the waterway. Watersheds are important because the surface water features and stormwater runo- within a watershed ultimately drain to other bodies of water. It is essential to consider these downstream impacts when developing and implementing water quality protection and restoration actions. Management of the environment has been primarily focused on specic issues such as air, land, and water.

It is supported by suitable examples and diagrams. The broad chapters included in the book are: Rainfed agriculture: Introduction, types, characteristics, distribution and importance; History of rainfed agriculture & watershed in India; Problems and prospects of rainfed agriculture in India; Soil and climatic conditions prevalent in rainfed areas; Drought: types, effect of water deficit on physio- morphological characteristics of the plants, Mechanism of crop adaptation under moisture deficit condition; Water harvesting: importance, its techniques, Efficient utilization of water through soil and crop management practices, Study of mulches and antitranspirants; Management of crops in rainfed areas; Contingent crop planning for aberrant weather conditions; Concept, objective, principles and components of watershed management, factors affecting watershed management; Integrated watershed development. The need for comprehensive information on rainfed farming relevant to undergraduate and postgraduate students of agriculture has been felt for quite some time. The advanced, diverse and need-based topics have been together for a systematic and comprehensive reading by the students and faculty in agriculture. The materials on subject matter is set forth in such a manner and order as to enable them to better understand and follow to a reasonable degree of uniformity and their approach to the problems of rainfed agriculture.

Rainfed agriculture is generally overlooked by development investors, researchers and policy makers due to limited confidence in its ability to increase agricultural production and development. However, research undertaken by a team of leading scientists from global organizations demonstrates its potential in achieving food security, improving livelihoods and most importantly addressing issues of equity and poverty reduction in dryland areas - the hot spots of poverty. On the basis of case studies from varied agricultural and ecological regions in Asia and Africa, chapters discuss the need for adopting new paradigms between rainfed and irrigated agriculture, catchment/micro-watershed management approaches, upgrades in science-based development and more investments in rainfed areas. Yield gaps for major rainfed crops are analysed globally and possible ways and means including technological, social, and institutional options to bridge the yield gaps are discussed in detail. Covering areas such as rainwater harvesting and its efficient use, the rehabilitation of degraded land and assessment methods for social, environmental and economic impacts, this book will be necessary for both academics and policy makers working in water management, agriculture and sustainable development.

Rapidly increasing population in the dynamic semi-arid agro-ecosystems in sub-Saharan Africa (SSA) highlights the necessity to increase food production, while at the same time safe-guarding other ecological systems that support human development and well-being. In the past, increases in crop production to keep pace with population growth in this region were largely achieved through the expansion of cultivated area. Today, we must also consider ways of improving the productivity of already existing cropping systems. elopment-oriented research and describes the integrated research approach of the SSI program, its interconnected research projects - their scope and methodologies

Focusing on the technical, social, and economic issues involved in watershed management, this interdisciplinary author team focuses on bettering land use practices and the condition of soil water resources. Integrated Watershed Management in the Global Ecosystem is a volume composed from an international symposium of the world's leading experts

The book “Textbook of Rainfed Agriculture and Watershed Management” has been written to fulfill the requirement of undergraduate students of agriculture faculty considering the syllabus of V Dean’s committee of ICAR. This book attempt to present the available information on dryland/rainfed agriculture and watershed management in a very simple, and lucid language in easily understandable manner. The book contains chapters on an introduction to rainfed agriculture, soil and climate, drought, soil and water conservation techniques, water harvesting, crop management, contingent crop planning for aberrant weather conditions and watershed management. The student community may harness the benefit from this book by understanding the fundamentals of dryland/ rainfed agriculture and watershed management. I hope this book will be very useful for the students, teachers, extension specialists and others interested in rainfed agriculture.
