Available in PDF, EPUB and Kindle. Book excerpt: Agricultural production in the semi-arid western United States is dependent on irrigation. Population in the seventeen western states has been and is expected to continue increasing. Groundwater levels are declining throughout the region with long-term pumping and increased demands leading to greater pumping lifts and costs, land subsidence, and salt water intrusion into groundwater basins. Construction and operation costs of future water development in these states will be great, both in dollars and in economic and social effects. Competition for the available water supply due to increased demands in both agricultural and non-agricultural sectors continues to increase. Although considerable attention has been given to some aspects of declining water supplies for irrigated agriculture in particular areas, this is the first volume to adress in a comprehensive manner the effects of scarce water supplies on agricultural production and the resultant impacts at regional, state, national, and international levels. Over seventy experts, representing all the major physical and social sciences as well as industries examine the issues and conclude that important decisions must be made at all levels of government and private enterprise if the prosperity and quality of life in the region are to be maintained. Specific technical, economic, institutional, and managerial solutions are recommended to forestall an impending water crisis. All segments of society--agriculturalists, urbanites, food processors, land developers, environmentalists, and others--have major stakes in the outcome of any action for future water supplies and distribution in the West.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Frequent droughts and rapidly depleting groundwater reserves have deepened the water scarcity crisis in Jordan. Even though most farms use 'water-saving' technologies, groundwater depletion continues at an alarming rate. We investigate how perceptions of physical water availability in the past are related to farmers' current irrigation behaviour--frequency of irrigation and methods used in determining irrigation need. Using primary data from a survey of 414 commercial farms in Mafraq and Azraq governorates, we find that respondents who perceived reduction in physical water availability and faced agricultural losses in the past irrigated more frequently and were more likely to use self-judgement in determining irrigation need. These relationships were more pronounced for smaller farms, farms with sandy soil, mono-cropping farms and farms where the owner was the manager. These effects were lower for farms that preferred internet-based and in-person approaches for receiving irrigation advice. In addition, while the frequency of irrigation was higher among stone-fruit farms, the probability of using self-judgement in determining irrigation need was higher in olive farms and vegetable farms. We argue that farmers' irrigation behaviour must be considered for groundwater management policy and planning in Jordan."--Page 6.

This book was released on 2003 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study attempts to re-frame the current thinking on groundwater development and the implications for food security. Groundwater is important in agriculture as it provides a reliable fallback when rainfeeding fails. It is therefore instrumental in managing risk and optimizing food production. However accessing groundwater has become habit and turned to dependency. Resources limits on many key aquifers have been exceeded and competition for groundwater has become intense. This study highlights the role of adaptive strategies in dealing with aquifer management and indicates directions of research and management.

Available in PDF, EPUB and Kindle. Book excerpt: Agricultural water management is a vital practice in ensuring reduction, and environmental protection. After decades of successfully expanding irrigation and improving productivity, farmers and managers face an emerging crisis in the form of poorly performing irrigation schemes, slow modernization, declining investment, constrained water availability, and environmental degradation. More and better investments in agricultural water are needed. In response, the World Bank, in conjunction with many partner agencies, has compiled a selection of good experiences that can guide practitioners in the design of quality investments in agricultural water. The messages of 'Shaping the Future of Water for Agriculture: A Sourcebook for Investment in Agricultural Water Management' center around the key challenges to agricultural water management, specifically: - Building policies and incentives - Designing institutional reforms - Investing in irrigation systems improvement and modernization - Investing in groundwater irrigation - Investing in drainage and water quality management - Investing in water management in rainfed agriculture - Investing in agricultural water management in multipurpose operations - Coping with extreme climatic conditions - Assessing the social, economic, and environmental impacts of agricultural water investments 'Shaping the Future of Water for Agriculture' is an important resource for those interested and engaged in development with a focus on agricultural water.

Download or read book Essays on the Economics of Groundwater Depletion and Management in Irrigated Agriculture written by Gabriela Perez-Quesada and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The depletion of groundwater stocks reduces the flow of economic value and the production of goods from the resource. This dissertation quantifies these effects in the context of the High Plains Aquifer in the central US. One particular challenge in estimating these effects that we overcome is that feedback effects from irrigation behavior affect resource conditions, which creates an endogeneity concern. We also provide new insights on the potential of collective efforts by irrigators to manage the resource. We study how heterogeneity in resource and user characteristics affect their individuals' willingness to support efforts to collectively reduce water use. The first chapter estimates how changes in groundwater stocks affect the returns to agricultural land. We avoid bias from feedback effects by exploiting hydrologic variation in pre-development saturated thickness that was determined by natural processes in previous geological eras. Simulation results reveal that the average annual present value of returns to land are expected to decrease in the High Plains region by $120.6 million in 2050, and by $250.5 million in 2100. The most severe decreases in returns to land are expected to occur in Texas, Kansas, and Colorado. When the initial saturated thickness is less than 70 feet, most of the economic impact (63%) of a decrease in the stock of groundwater occurs through an adjustment in irrigated acreage (extensive margin), while 37% occurs through reduced irrigated rental rates (intensive margin). When saturated thickness is larger, nearly all of the response is at the extensive margin. The second chapter examines how observed differences in the stock of groundwater affect corn production. To account for the endogeneity of groundwater stock, we exploit variation in current saturated thickness due to variation in pre-development saturated thickness. Simulation results reveal that the annual production of corn would decrease by 48.1 million bushels in the north portion of the High Plains Aquifer due to a uniform 10 ft decrease in saturated thickness, whereas the annual production of corn would decrease by 15.7 million bushels in the south. Further, we find that when initial saturated thickness is less than 70 ft, most of the impact on corn production of a decrease in the stock of groundwater occurs through an adjustment in irrigated acres in both the north and the south. When saturated thickness is larger than 70 ft, then the adjustment is mostly through a change in cropping patterns on irrigated land in the south but still through irrigated acres in the north. The third chapter uses unique data obtained from consequential stated preference surveys in Kansas to explore the factors that influence farmers preferred reductions in groundwater use through a water conservation program implemented by a Groundwater Management District. Our results reveal that farmers located in areas where the aquifer is more depleted support larger reductions in groundwater use. But we also find that characteristics of the users matter as much or more than the status of the aquifer in determining support. Opposition to reductions in water use are strongest among farmers who strongly agree that water rights are a private property, landlords and those who irrigate a larger proportion of their farm. Further, we evaluate farmers' preferences for the methods of assigning water allocations. We find that none of the options are preferred by a majority of farmers and there is no clear evidence that aquifer characteristics or observed farmer characteristics are the key factors affecting the probability that a farmer ranks a method as the best option. This makes it difficult for groundwater managers to identify which method is more likely to be considered fair by farmers. Our results are informative for managers of water throughout Kansas, the High Plains and other regions where conserving water resources is a high priority and localized and stakeholder-driven conservation plans could be a solution.
Download or read book Safe Use of Wastewater in Agriculture written by Hiroshan Hettiarachchi and published by Springer. This book was released on 2018-03-09 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a broad and global level description of the current status of wastewater use in agriculture and then brings the readers to various places in the MENA Region and Europe to explain how some countries and regions have addressed the challenges during implementation. On a global scale, over 20 million hectares of agricultural land are irrigated using wastewater. This is one good, and perhaps the most prominent, example of the safe use potential of wastewater. Water scarcity and the cost of energy and fertilisers are among the main factors driving millions of farmers and other entrepreneurs to make use of wastewater. In order to address the technical, institutional, and policy challenges of safe water reuse, developing countries and countries in transition need clear institutional arrangements and more skilled human resources, with a sound understanding of the opportunities and potential risks of wastewater use. Stakeholders in wastewater irrigation who need to implement from scratch or improve current conditions, find it difficult to gather the necessary information on practical implementation aspects. The main objective of this book is to bridge that gap.
Download or read book Sustainability of Irrigated Agriculture written by L.S. Pereira and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigated agriculture and the use of water resources in agriculture face the challenges of sustainable development. Research has advanced our knowledge of water use by crops, soil-water-solutes interactions, and the engineering and managerial tools needed to mobilize, convey, distribute, control and apply water for agricultural production. However, the achievements booked in user practice have revealed the need for new developments in the areas of resource conservation, control of environmental and health impacts, modernisation of technologies and management, economic viability and the social acceptance of changes. The contributions to Sustainability of Irrigated Agriculture cover most of the relevant disciplines. Besides its multidisciplinarity, the different origins, experience, backgrounds and practices of the authors provide a wide, in-depth analysis of the various aspects of water resource utilization in agriculture. The papers review scientific, technical and managerial aspects, highlighting the main problems, issues and future developments. The book covers the different aspects of sustainability, including environmental, technical, economic, institutional and social ones. Advances in irrigation science and engineering are dealt with, both on- and off-farm. Special attention is paid to the different components of water quality management, to the transfer of technology, and to capacity building.
