Book Description
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 title is part of UC Press's Voices Revived program, which commemorates University of California Press's mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1984.

Book Description
"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.

Book Description
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.
