The Economics and Management of Water and Drainage in Agriculture by Ariel Dinar,David Zilberman Pdf
Jan van Schilfgaarde, USDA Agricultural Research Service and National Research Council Committee on Irrigation-Induced Water Quality Problems In 1982, a startling discovery was made. Many waterbirds in Kesterson National Wildlife Refuge were dying or suffering reproductive failure. Located in the San Joaquin Valley (Valley) of California, the Kesterson Reservoir (Kesterson) was used to store agricultural drainage water and it was soon determined that the probable cause of the damage to wildlife was high concen trations of selenium, derived from the water and water organisms in the reservoir. This discovery drastically changed numerous aspects of water management in California, and especially affected irrigated agriculture. In fact, the repercussions spilled over to much of the Western United States. For a century, water development for irrigation has been a religiously pursued means for economic development of the West. The primary objective of the Reclamation Act of 1902 was, purportedly, the development ofirrigation water to support family farms which, in turn, would enhance the regional economy (Worster, 1985).

The Fall and Rise of the Wetlands of California's Great Central Valley by Philip Garone Pdf
This is the first comprehensive environmental history of California’s Great Central Valley, where extensive freshwater and tidal wetlands once provided critical habitat for tens of millions of migratory waterfowl. Weaving together ecology, grassroots politics, and public policy, Philip Garone tells how California’s wetlands were nearly obliterated by vast irrigation and reclamation projects, but have been brought back from the brink of total destruction by the organized efforts of duck hunters, whistle-blowing scientists, and a broad coalition of conservationists. Garone examines the many demands that have been made on the Valley’s natural resources, especially by large-scale agriculture, and traces the unforeseen ecological consequences of our unrestrained manipulation of nature. He also investigates changing public and scientific attitudes that are now ushering in an era of unprecedented protection for wildlife and wetlands in California and the nation.

Preliminary Planning Alternatives for Solving Agricultural Drainage and Drainage-Related Problems in the San Joaquin Valley by U. S. Department Of The Interior Pdf
Excerpt from Preliminary Planning Alternatives for Solving Agricultural Drainage and Drainage-Related Problems in the San Joaquin Valley: Executive Summary The severity of the toxics problem has been known only a relatively short time. It came into focus about 6 years ago with the discovery of migratory bird deaths and deformities linked to high levels of selenium in agricultural drainage water at Kesterson Reservoir. Concentrations of drainage-water contaminants and rates of deformities higher than those found at Kesterson are now being found associated with evaporation ponds in the Tulare Basin, in the southern part of the valley. Drainage problems affecting agriculture are almost as old as irrigated agriculture in the valley. As early as the 18go's, some cultivated lands were forced out of production because of salt and drainage problems. Despite the long history of drainage problems, efforts to solve them have been fragmented and remain uncompleted. Many people involved in drainage issues believe that a sustainable, long-term solution to the problems affecting agriculture will have to be accomplished in several phases. The first, and probably most critical, phase involves solving the problem of toxicants such as selenium. Understanding of drainage conditions and problems in the valley has been greatly improved in the last few years, and critical evaluation of potential measures for solving those problems is required. Some 70 individual options that potentially could contribute to management of the problems have been identified by the Drainage Program, including measures that are currently being practiced as well as those that are as yet unproven and still under investigation. This report presents preliminary planning alternatives utilizing several of these options, all of which represent currently available technologies. The alternatives represent short-term or interim fixes to address problems expected to exist in the year 2000; in most cases, however, the measures and associated benefits would extend for many years. The Drainage Program is in the process of developing additional alternatives to meet both short and long-term needs.
