Rainfed Agriculture: Unlocking the Potential (Comprehenisve Assessment of Water Management in 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. 41RgwoL0SGL._SS500_.pdf......Page 1 696B7A72d01......Page 2 Contents......Page 6 Contributors......Page 8 Series Foreword......Page 11 Foreword......Page 13 Preface......Page 14 Acknowledgements......Page 16 1 Rainfed Agriculture – Past Trends and Future Prospects......Page 18 2 Zooming in on the Global Hotspots of Rainfed Agriculture in Water-constrained Environments......Page 53 3 Water Resource Implications of Upgrading Rainfed Agriculture – Focus on Green and Blue Water Trade-offs......Page 61 4 Tectonics–Climate-linked Natural Soil Degradation and its Impact in Rainfed Agriculture: Indian Experience......Page 71 5 Determinants of Crop Growth and Yield in a Changing Climate......Page 90 6 Yield Gap Analysis: Modelling of Achievable Yields at Farm Level......Page 98 7 Can Rainfed Agriculture Feed the World?

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.

"This book is based on research undertaken by a team of leading scientists from 10 global organizations. Chapters consider the potential of rainfed agriculture on the basis of case studies for different regions in Asia and Africa with the aim to assess the need of water for achieving food security and reducing poverty. 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."--Publisher's website Based on the case studies from varied agricultural and ecological regions in Asia and Africa, this book discusses 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.
