Klappentext 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 analyzed 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. ."..the book presents important contributions towards a more efficient capture and use of rainfall, with a major focus on engineering and agronomic practices, but also elaborating on the necessary genetic enhancement." Zusammenfassung Using case studies from Asia and Africa! this book discusses rainfed and irrigated agriculture! catchment/micro-watershed management approaches! upgrades in science-based development and more investment in rainfed areas. It covers rainwater harvesting! rehabilitation of land and social! environmental and economic impact assessment. Inhaltsverzeichnis 1. Rainfed Agriculture - Past Trends and Future Prospects; 2.
