Water Productivity In Rainfed Agriculture

by Hodson Makurira, Water Productivity In Rainfed Agriculture Books available in PDF, EPUB, Mobi Format. Download Water Productivity In Rainfed Agriculture books, The challenge of water scarcity as a result of insufficient seasonal rainfall and dry spell occurrences during cropping seasons is compounded by inefficient agricultural practices by smallholder farmers where insignificant soil and water conservation efforts are applied. The hypothesis of this research is that many of the past research efforts have taken a fragmented approach to deal with the challenges facing subsistence farmers in rainfed systems. The research has been conducted in the semi-arid Makanya catchment of northern Tanzania and has successfully applied different analytical techniques to better understand soil and water interactions at field scale. It has been demonstrated that there is indeed scope to increase crop water productivity provided the local farmers adopt more efficient cultivation techniques. Substantial yield increases occur as a result of diverting runoff and these further improve when other techniques such as ripping, application of manure and cover cropping are introduced. This confirms that no single solution exists to solve the problem of low yields in rainfed farming systems. However, even with these promising results, the research has shown that there is room to further improve the efficiency of crop water use through improvement in research approaches and exploration of better techniques.

Water Productivity In Agriculture

by J. W. Kijne, Water Productivity In Agriculture Books available in PDF, EPUB, Mobi Format. Download Water Productivity In Agriculture books, First title in a major new seriesAddresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental securityDraws from scientists having a multitude of disciplines to approach this important problemIn a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.

Rainfed Agriculture

by Suhas Pralhad Wani, Rainfed Agriculture Books available in PDF, EPUB, Mobi Format. Download Rainfed Agriculture books, 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.

Key Concepts In Water Resource Management

by Jonathan Lautze, Key Concepts In Water Resource Management Books available in PDF, EPUB, Mobi Format. Download Key Concepts In Water Resource Management books, The vocabulary and discourse of water resource management have expanded vastly in recent years to include an array of new concepts and terminology, such as water security, water productivity, virtual water and water governance. While the new conceptual lenses may generate insights that improve responses to the world’s water challenges, their practical use is often encumbered by ambiguity and confusion. This book applies critical scrutiny to a prominent set of new but widely used terms, in order to clarify their meanings and improve the basis on which we identify and tackle the world’s water challenges. More specifically, the book takes stock of what several of the more prominent new terms mean, reviews variation in interpretation, explores how they are measured, and discusses their respective added value. It makes many implicit differences between terms explicit and aids understanding and use of these terms by both students and professionals. At the same time, it does not ignore the legitimately contested nature of some concepts. Further, the book enables greater precision on the interpretational options for the various terms, and for the value that they add to water policy and its implementation.

by David Molden, Water For Food Water For Life Books available in PDF, EPUB, Mobi Format. Download Water For Food Water For Life books, Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development.

Water And Sustainable Agriculture

by Iván Francisco García-Tejero, Water And Sustainable Agriculture Books available in PDF, EPUB, Mobi Format. Download Water And Sustainable Agriculture books, Irrigated agriculture, a vital component of general agriculture, supplies fruits, vegetables, and cereals consumed by humans and grains fed to animals. Consequently, agriculture is the largest user of fresh water globally, and irrigation practices in many parts of the world are biologically, economically, and socially unsustainable. Water management should balance the need for agricultural water and the need for a sustainable environment. Water-use efficiency is the prime challenge in worldwide farming practices where problems of water shortages are widespread. Currently, agriculture is undergoing significant changes in innovative irrigation, fertilizer technology, and agronomic expertise. These elements constitute a vital platform for sustainable agricultural success and for preventing environmental damage. This review presents several processes linked to environmental irrigation, balancing environmental protection with improved agricultural production.
