Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides an overview of the principles required for a service orientation in the management of irrigation and drainage systems. The material covered is designed to emphasize an area largely neglected in the irrigation and drainage management literature. The dominating philosophy underlying this book is that irrigation and drainage systems must be managed as a service business responsive to the needs and changing requirements of its customers. It is postulated that this service approach to the management of irrigation and drainage systems consitutes a key element of the startegy that is needed to improve the current level of performance of many irrigation and drainage systems worldwide. Enhanced performance of irrigation is a prerequisite if we are to face the enormous challenge of producing greater quantities of food to meet the demand of a growing population. This is particularly the case in an environment with increasing competition for water from industry and urban water users, set against mounting concerns about environmental sustainability.

Book excerpt: Water scarcity has become one of the greatest challenges facing humankind today. Its scarcity is compounded by climate change and increasing demand from a growing population. In South Africa, over 60% of the available freshwater resources are used in agriculture, mainly in irrigated agriculture. There is an urgent need to promote sustainable irrigation technologies that optimize food production without increasing water applied and with positive environmental spinoffs. Sustainable irrigation technologies and practices could enhance water use efficiency (WUE) and productivity in agriculture and reduce environmental burdens, including energy use. This chapter highlights some of the innovative irrigation practices and technologies that enhance food production and, at the same time, reduce water use in agriculture. The chapter broadly discusses WUE and water productivity (WP) in irrigated agriculture from engineering and agronomic perspectives. The chapter further highlights some of the environmental impacts of irrigation expansion and the possible solutions. We further provide the importance of accurate spatial information on irrigated areas to inform policy on irrigation expansion. The Water Research Commission (WRC) of South Africa has been spearheading research on the sustainable use of water for the past 50 years as part of its research agenda. In Ting, D. S.-K.; O’Brien, P.

Download or read book Producing More Rice with Less Water from Irrigated Systems written by Luis Catasús Guerra and published by IWMI. This book was released on 1998 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, we have witnessed a growing scarcity of and competition for water around the world. As the demand for water for domestic, municipal, industrial, and environmental purposes rises in the future, less water will be available for agriculture. But the potentials for new water resource development projects and expanding irrigated area are limited. We must therefore find ways to increase the productivity of water used for irrigation. This paper reviews the literature on irrigation efficiency and on the potential for increasing the productivity of water in rice-based systems. It stresses the continuing confusion over the concepts of irrigation efficiency and water productivity. It identifies the reasons for the wide gap between water requirement and actual water input (both irrigation diversions and rainfall) in irrigated rice production systems and discusses potential opportunities for increasing water productivity both on-farm and at the system level. Based on the reported low farm and system level irrigation efficiencies, the potentials for water savings in rice production appear to be very large. But we do not know the degree to which various farm and system interventions will lead to sustainable water savings in the water basin until we can quantify the downstream impact of the interventions. Studies on the economic benefits and costs, and environmental aspects of alternative interventions are also lacking. This paper emphasizes the need to measure the productivity of water at farm, system, and basin levels, and to understand how the productivity at one level relates to the productivity at another. Without water balance studies to measure productivity at these different scales, it is not possible to identify the potential economic benefits of alternative interventions and the most appropriate strategies for increasing irrigation water p productivity in rice-based systems.

This book was released on 2019-04-21 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: For nearly a century, scientific advances have fueled progress in U.S. agriculture to enable American producers to deliver safe and abundant food domestically and provide a trade surplus in bulk and high-value agricultural commodities and foods. Today, the U.S. food and agricultural enterprise faces formidable challenges that will test its long-term sustainability, competitiveness, and resilience. On its current path, future productivity in the U.S. agricultural system is likely to come with trade-offs. The success of agriculture is tied to natural systems, and these systems are showing signs of stress, even more so with the change in climate. More than a third of the food produced is unconsumed, an unacceptable loss of food and nutrients at a time of heightened global food demand. Increased food animal production to meet greater demand will generate more greenhouse gas emissions and excess animal waste. The U.S. food supply is generally secure, but is not immune to the costly and deadly shocks of continuing outbreaks of food-borne illness or to the constant threat of pests and pathogens to crops, livestock, and poultry. U.S. farmers and producers are at the front lines and will need more tools to manage the pressures they face. Science Breakthroughs to Advance Food and Agricultural Research by 2030 identifies innovative, emerging scientific advances for making the U.S. food and agricultural system more efficient, resilient, and sustainable. This report explores the availability of relatively new scientific developments across all disciplines that could accelerate progress toward these goals. It identifies the most promising scientific breakthroughs that could have the greatest positive impact on food and agriculture, and that are possible to achieve in the next decade (by 2030).

This book was released on 2012-05-04 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an outcome from the International Expo 'Water and Sustainable Development' held in Zaragoza (Spain) in 2008. Support from the Spanish Ministry of Environment, Caja Rioja, Government of Aragon, and the World Bank is acknowledged. 'Few resources will play a more important role in shaping our economic future, or face more daunting challenges, than water. This internationally acclaimed team of experts has produced a first-rate volume that is full of intriguing, practical ideas for meeting those challenges in a rich variety of institutional settings.' Tom Tietenberg, Mitchell Family Professor of Economics, Emeritus, Colby College, USA 'This volume brings together two critical but interrelated dimensions of water challenge, i.e. water pollution, particularly from non-point sources, and water conservation. The editors are well known experts on the subject as are the contributors.' R. Maria Saleth, International Water Management Institute, Sri Lanka and Associate Editor, Water Policy 'The profound contribution of this volume is that it brings together various economic concepts and policy dilemmas regarding water shortages, non-point source pollution, efficiency of water use and irrigation technology. Recommended reading for anyone working in the area of water management.' Henk Folmer, University of Groningen and Wageningen University, The Netherlands As countries face deteriorating water and environmental quality as well as water shortages, pollution control and the efficiency of water use become of paramount importance. Agriculture is one of the main non-point polluters of water bodies and irrigation for agriculture is one of the main consumers of water. While it is very hard to regulate pollution from agriculture, attempts have been made via economic and command and control instruments, and also through investments in technologies and ecosystems recovery. Coping with non-point pollution takes the form of both policy intervention and technology development. Likewise it is recognized that irrigation efficiency varies across countries, influenced by both technology and supporting adoption policies. Countries that lead in irrigation technology and supporting policies have certain traits in common. They face very high scarcity and are pushed to find innovative solutions, both technical and policy related. The recent multibillion investments in irrigation technologies in Spain, and similar proposals in Australia, for example, highlight the potential of irrigation technologies to cope with scarcity and water quality degradation. This book reviews all of the above issues, presents experiences in selected countries, and assesses the degree of success of alternative policies for coping with non-point water pollution and improving irrigation efficiency.
