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.

Agricultural water supplies are becoming increasingly uncertain in the western United States due to rising demand from competing water users, environmental restrictions on surface water withdrawals due to water quality and endangered species concerns, and, potentially, climate-induced hydrological changes. Since many rural areas in the West depend economically upon irrigated agriculture, increased water supply variability may not only affect the agricultural sector, but may also have significant regional economic impacts. This study investigates the distribution and magnitude of farm and community level economic impacts of water supply fluctuations through a case study of an irrigation district located in an agriculturally-dependent county in southeastern Oregon. In addition to estimating the value of irrigation water, this study examines the effectiveness of three strategies to mitigate the economic consequences of fluctuating water supplies: 1. increased accuracy of water supply forecasts, 2. additional irrigation technology adoption, and 3. implementation of a water market or water bank. Two models were utilized to estimate the economic impacts. First, a linear programming model written in the General Algebraic Modeling System (GAMS) was used to estimate the profit and revenue effects of four water supply scenarios on six representative farm types. Second, results from the linear program were used to conduct a regional impact analysis in an input-output model to ascertain how the farm revenue effects impact community-level employment and income. Results indicate that expected annual revenue losses due to water shortages under current conditions range from 4 to 14%, while the expected annual profit losses range from 9 to 12%. Expected annual farm profit losses on the large ranches, feedlot operations, and row crop farms comprise 75% of total expected farm profit losses. County-level employment and income losses due to water supply variations in this irrigation district (comprising 16% of irrigated land in the county) were limited to less than 1%, even in the most severe water shortage scenario. Results also suggest that of the three mitigating strategies, additional irrigation technology adoption best reduces farm and community-level economic losses. A doubling of the current levels of sprinkler and drip irrigation technology resulted in a 5% increase in expected farm profits and a 0.1% increase in expected county income. Although water trading and improved accuracy of water forecasts similarly reduced farm profit losses due to water shortages, both resulted in greater expected farm revenue losses and hence greater community-level economic losses.

This article evaluates irrigated agriculture sector response and resultant economic impacts of climate change for a part of the Murray Darling Basin in Australia. A water balance model is used to predict reduced basin inflows for mild, moderate and severe climate change scenarios involving 1, 2 and 4°C warming, and predict 13, 38 and 63% reduced inflows. Impact on irrigated agricultural production and profitability are estimated with a mathematical programming model using a two-stage approach that simultaneously estimates short and long-run adjustments. The model accounts for a range of adaptive responses including: deficit irrigation, temporarily following of some areas, permanently reducing the irrigated area and changing the mix of crops. The results suggest that relatively low cost adaptation strategies are available for a moderate reduction in water availability and thus costs of such a reduction are likely to be relatively small. In more severe climate change scenarios greater costs are estimated. Adaptations predicted include a reduction in total area irrigated and investments in efficient irrigation. A shift away from perennial to annual crops is also predicted as the latter can be managed more profitably when water allocations in some years are very low.

The report assesses the occurrence and impacts of drought, the current policies underlying drought management as well as the mitigation measures and responses adopted in the Near East and North Africa region, with a focus on the Agriculture Sector. It is the third of a series of similar studies carried out in different regions and countries of the world, with the objective of shedding light on drought effects, sensitizing policy-makers for the much needed paradigm shift to pro-active drought management planning and providing guidance for the development of such policies. The studies are carried out by FAO, in collaboration with the Water for Food Institute, University of Nebraska-Lincoln, USA, as a direct contribution to FAO's Strategic Objective "increasing the resilience of livelihoods to disasters" and Strategic Objective "make agriculture, forestry and fisheries more productive and sustainable".
