Available in PDF, EPUB and Kindle. Book excerpt: Non-point source (NPS) control strategies were initiated in California in the late 1980's under the authority of the Porter-Cologne Act and eventually for the development of total maximum daily load (TMDL) plans. Most of the NPS TMDLs developed for California's Central Valley region (CV) were related to pesticides. Efforts to reduce pesticide loads and concentrations began in earnest around 1990. The NPS control strategies either encouraged or mandated the use of management practices (MPs). Although TMDLs were largely developed for pesticides, the resultant MPs would likely have affected the runoff of other potential pollutants (specifically, nutrients). This study evaluates the effectiveness of agricultural NPS control strategies implemented in California's CV between 1990 and 2013 by comparing surface-water nutrient concentration and load trends between two periods. In general, use of MPs were encouraged during a "voluntary" period (1990 to 2004) and mandated during an "enforcement" period (2004 to 2013). Nutrient water-quality data were obtained from U.S. Geological Survey National Water Inventory System (NWIS) and the California Environmental Data Exchange Network (CEDEN). Nutrient concentrations, loads, and trends were estimated by using the recently developed Weighted Regressions on Time Discharge and Season (WRTDS) model. Sufficient total phosphorus (TP), total nitrogen (TN) and nitrate (NO3) data were available to compare the voluntary and enforcement periods for seven sites within the lower Sacramento and San Joaquin basins. For six of the seven sites, flow-normalized mean annual concentrations of TP and NO3 decreased at a faster rate during the enforcement period than during the voluntary period. Concentration changes during similar years and ranges of flow conditions suggest that MPs designed for pesticides, reduced nutrient loads. Results show that enforceable NPS policies, and accelerated MP implementation, limits NPS pollution, and may control runoff of non-targeted constituents such as nutrients.

Download or read book Wetlands written by Committee on Characterization of Wetlands and published by National Academies Press. This book was released on 1995-09-20 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.

Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Download or read book Arid Environments and Sustainability written by Hasan Arman and published by BoD – Books on Demand. This book was released on 2018-05-23 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arid environments are basically associated with water scarcity. Therefore, soils will have an extremely low moisture level to support plant and animal life as well as human social life. Sustainability is the long durability of systems and processes within various adapted environmental conditions. Recently, systematic scientific studies on arid environments and sustainability have become more attractive, critical, and sound than the previous years. Sharing such experiences related to different environmental circumstances will absolutely help scientists and decision-makers to have better interpretation of their own environment. By learning lessons, appropriate, fast, and effective approaches require to implement for overwhelming such problems. Such actions will certainly lead to more secure and sustainable environments for plant, animal, and human life.
