This book was released on 2018-06-27 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is growing interest in water accounting, why it is needed, what benefits it brings, and equally important, how it can be put into practice. Water accounting is not a new idea, yet it is an alarmingly simple one. It is about quantifying water resources and uses of water, much like financial accounts provide information on income and expenditure. Interest in water accounting is based on the premise that ‘We cannot plan and manage what we do not measure’ – a statement that few would disagree with. However, given the current focus on water as a precious and limiting resource, the risks of extreme floods and droughts, and water’s central role in the 2030 Agenda, it is difficult to understand why so little attention is given to water accounting and to making sure we have enough water. Indeed, estimates suggest that by 2050, if we continue with our current approach to water management, global water demand will exceed supply by over 40%, which would put at risk 45% of global GDP, 52% of the world’s population, and 40% of grain production (WWDR, 2016). This concern is supported by the World Economic Forum that consistently ranks water crises as a top global risk (WEF, 2015). Reports from South Africa (January 2018) suggesting that Cape Town may be the world’s first major city to face the prospect of running out of water following severe drought, is a timely ‘wake-up call’ for everyone to focus on accounting for water.
Download or read book Agricultural Water Management written by National Research Council and published by National Academies Press. This book was released on 2007-03-20 with total page 158 pages. 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.
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.
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 excerpt: In December 2002, a group of specialists on water resources from the United States and Iran met in Tunis, Tunisia, for an interacademy workshop on water resources management, conservation, and recycling. This was the fourth interacademy workshop on a variety of topics held in 2002, the first year of such workshops. Tunis was selected as the location for the workshop because the Tunisian experience in addressing water conservation issues was of interest to the participants from both the United States and Iran. This report includes the agenda for the workshop, all of the papers that were presented, and the list of site visits.

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.
