Download or read book Salinity and Drainage in San Joaquin Valley California written by Andrew C. Chang and published by Springer. This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book documents the history of irrigated agriculture and drainage in the San Joaquin Valley, and describes the hydrology and biogeochemical processes of salts and selenium, remediation technologies for salts and trace elements and policy and management options. The contents are comprised of fourteen chapter-length independent treatises, each depicting with fresh perspective a distinctive salinity drainage topic. The opening chapters detail the evolution of irrigated agriculture, and depict the geochemical and hydrological processes that define the San Joaquin Valley, including the physics, chemistry, and biology attributes that impact water management policies and strategies. Next, the contributors address the biogeochemistry of selenium, the role of plants in absorbing it from soils, and the processes involved in retaining and concentrating dissolved salts in drainage water. Further chapters describe on-farm and plot-level irrigation provisions to reduce agricultural drainage outputs and examine their effects on plant performance. This volume offers realistic policy analysis of water management options for irrigated agriculture in the Valley and assesses their respective outcomes, if implemented. Also included is an international perspective on the sustainability of irrigated agriculture there.

Available in PDF, EPUB and Kindle. Book excerpt: Biotreatment of Agricultural Wastewater is based on a symposium held in Lake Arrowhead, California in 1986, supported by a coalition of federal, state, and local agencies, and sponsored by the engineering firm of Swanson/Oswald Associates (Lafayette, California) and the research and development firms of Aquasearch, Inc. and EcoTechnology Corp. (La Jolla, California). This book is a synopsis of topics covered by world renowned experts on the biology and aquaculture of algae and bacteria and on the engineering of industrial scale systems for biological wastewater treatment and economists that were gathered to evaluate historically proven systems and develop new and innovative approaches to the biological treatment of agriculture wastewater.

This book was released on 2020-03-03 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Agriculture and the Environment written by C.A. Edwards and published by Elsevier. This book was released on 2012-12-02 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until the 1980s, global increases in food production exceeded the concomitant growth of human populations. However, progressively agriculture is becoming unable to meet the world-wide per capita needs for food. Unless there is major international cooperation in addressing the problems associated with population control, it is predicted that the global human population will reach more than 14 billion by the year 2050, with provision of adequate food, fuel and space for such an increased population unachievable. These problems are accentuated by factors such as world-wide reductions in soil fertility, the accelerating degradation of land that is suitable for food production through soil erosion, the world-wide trend for migration of human populations from rural habitats to cities and extremely rapid rates of global deforestation. Possible solutions to global sustainability in agriculture and natural resources must involve an integration of ecological, sociological, cultural, and economic considerations, as well as mandated international and national policies. This publication outlines these problems and attempts to seek solutions.

This book was released on 2012-12-06 with total page 930 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).
Download or read book Environmental Contaminants in Wildlife written by James P. Meador and published by CRC Press. This book was released on 1996-03-20 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have been written about the effects of toxic chemicals on wildlife, but none has focused on the practical question, "How much of a chemical in the tissues of an animal is harmful?" This book deals exclusively with that question. This comprehensive reference will certainly become the standard resource on the topic, offering authoritative and sound advice on many environmental contaminants. With chapters written by outstanding experts in their respective fields, this is not only a scholarly collection of discussions on different chemicals, but, for those who have the day-to-day task of evaluating the harm of environment contaminants to wildlife, this book will provide answers on, for example, how to interpret 1 ppm lead in the liver of a duck or fish. The authors explain the snags of interpreting data that are sometimes conflicting or insufficient, providing the reader with helpful advice on how to cope with such data. Each chapter reviews literature on a specific chemical, followed by a easy-to-understand summary providing technical guidance. For many years this book will remain the preeminent reference on how to interpret contaminant levels of organochlorine pesticides, PCBs, dioxins, PAHs, metals, selenium, and fluorides in wildlife.
