Available in PDF, EPUB and Kindle. Book excerpt: This report contains a collection of papers from a workshopâ€"Strengthening Science-Based Decision-Making for Sustainable Management of Scarce Water Resources for Agricultural Production, held in Tunisia. Participants, including scientists, decision makers, representatives of non-profit organizations, and a farmer, came from the United States and several countries in North Africa and the Middle East. The papers examined constraints to agricultural production as it relates to water scarcity; focusing on 1) the state of the science regarding water management for agricultural purposes in the Middle East and North Africa 2) how science can be applied to better manage existing water supplies to optimize the domestic production of food and fiber. The cross-cutting themes of the workshop were the elements or principles of science-based decision making, the role of the scientific community in ensuring that science is an integral part of the decision making process, and ways to improve communications between scientists and decision makers.
Book Synopsis Urban Agriculture and Small Farm Irrigation by : Tyler Pratt
Download or read book Urban Agriculture and Small Farm Irrigation written by Tyler Pratt and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The landscape of water in Utah is changing due to population growth, conversion of agricultural land to urban development, and increasing awareness of water scarcity. The Utah Division of Water Resources forecasts that the currently developed water supplies will not be enough to provide for Utah0́9s future population, and is pursuing conservation and new development to meet the state0́9s anticipated needs. Along with the urban growth Utah is experiencing a growing urban and small farm agricultural sector, but knowledge of water use in these operations is limited. Further research in this area aids in understanding the impact of land use change on the state0́9s hydrology, aids the state water authorities in water use estimates, assists farmers in moving towards wiser water management, and helps Utah State University Extension better meet the needs of small irrigators. My research creates a clearer picture of urban and small farm agricultural irrigation in Utah. For the 2015 growing season I performed irrigation evaluations for 24 urban and small farms in Cache Valley, and I explore the results from both case study and statistical perspectives. My results show a great degree of heterogeneity with irrigation efficiencies ranging from 6% to 100%. In general, small fields had greater irrigation depths than large fields, and surface irrigated fields applied higher depths than sprinkle and drip irrigated fields. Yet a big influence on efficiency was management, as fields relying on a set schedule had higher depths than fields that were irrigated inconsistently due to other factors. Therefore, water conservation programs focused on reducing irrigated area or providing technological alternatives may not result in true water savings if the effect of management is ignored. In particular, urban and small farmers need increased awareness of how management can result in savings of time and money, and improved knowledge of how to measure application rates, improve application uniformity, and scheduling techniques. With improvements in these areas, water management on urban and small farms can be improved, therein helping the urban and small farm irrigators themselves as well as the state in meeting its future water needs.

Book Synopsis Irrigation Management by : Martin Burton
Download or read book Irrigation Management written by Martin Burton and published by CABI. This book was released on 2010 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many countries irrigated agriculture consumes a large proportion of the available water resources, often over 70% of the total. There is considerable pressure to release water for other uses and, as a sector, irrigated agriculture will have to increase the efficiency and productivity of its water use. This is particularly true for manually operated irrigation systems managed by government agencies, which provide water for a large number of users on small landholdings and represent 60% of the total irrigated area worldwide. Drawing on the author's 30 years of experience in some 28 countries, this book offers knowledge of the management of irrigation and drainage systems, including traditional technical areas of systems operation and maintenance, and expanding managerial, institutional and organizational aspects. Chapters provide guidelines to improve management, operation and maintenance processes, which move management thinking out of traditional public-sector mindsets to a more customer-focused, performance-oriented service delivery. As a practical guide to improve efficiency and productivity in irrigated agriculture, this book will be essential reading for irrigation managers and technicians as well as students and policy makers in water management, agriculture and sustainable development.

Book Synopsis Sustainable Water Management in Smallholder Farming by : Sara Finley
Download or read book Sustainable Water Management in Smallholder Farming written by Sara Finley and published by CABI. This book was released on 2016-07-27 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is critical to all human activities, but access to this crucial resource is increasingly limited by competition and the effects of climate change. In agriculture, water management is key to ensuring good and sustained crop yields, maintaining soil health, and safeguarding the long-term viability of the land. Water management is especially challenging on smallholder farms in resource-poor areas, which tend to be primarily rainfed and thus highly dependent on unreliable rainfall patterns. Sustainable practices can help farmers promote the development of soils, plants and field surfaces to allow maximum retention of water between rains, and encourage the efficient use of each drop of water applied as irrigation. Especially useful for farmers' groups, agricultural extension workers, NGOs, students and researchers working with farmers in dryland areas, this comprehensive yet concise book is a practical and accessible resource for anyone interested in sustainable water management.

Book Synopsis Drip Irrigation for Agriculture by : Jean-Philippe Venot
Download or read book Drip Irrigation for Agriculture written by Jean-Philippe Venot and published by Routledge. This book was released on 2017-07-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Initially associated with hi-tech irrigated agriculture, drip irrigation is now being used by a much wider range of farmers in emerging and developing countries. This book documents the enthusiasm, spread and use of drip irrigation systems by smallholders but also some disappointments and disillusion faced in the global South. It explores and explains under which conditions it works, for whom and with what effects. The book deals with drip irrigation 'behind the scenes', showcasing what largely remain 'untold stories'. Most research on drip irrigation use plot-level studies to demonstrate the technology’s ability to save water or improve efficiencies and use a narrow and rather prescriptive engineering or economic language. They tend to be grounded in a firm belief in the technology and focus on the identification of ways to improve or better realize its potential. The technology also figures prominently in poverty alleviation or agricultural modernization narratives, figuring as a tool to help smallholders become more innovative, entrepreneurial and business minded. Instead of focusing on its potential, this book looks at drip irrigation-in-use, making sense of what it does from the perspectives of the farmers who use it, and of the development workers and agencies, policymakers, private companies, local craftsmen, engineers, extension agents or researchers who engage with it for a diversity of reasons and to realize a multiplicity of objectives. While anchored in a sound engineering understanding of the design and operating principles of the technology, the book extends the analysis beyond engineering and hydraulics to understand drip irrigation as a sociotechnical phenomenon that not only changes the way water is supplied to crops but also transforms agricultural farming systems and even how society is organized. The book provides field evidence from a diversity of interdisciplinary case studies in sub-Saharan Africa, the Mediterranean, Latin America, and South Asia, thus revealing some of the untold stories of drip irrigation.
