Download or read book Water Quality and Agriculture written by James Shortle and published by Springer Nature. This book was released on 2021-06-12 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water pollution control has been a top environmental policy priority of the world’s most developed countries for decades, and the focus of significant regulation and public and private spending. Yet, significant water quality problems remain, and trends for some pollutants are in the wrong direction. This book addresses the economics of water pollution control and water pollution control policy in agriculture, with an aim towards providing students, environmental policy analysts, and other environmental professionals with economic concepts and tools essential to understanding the problem and crafting solutions that can be effective and efficient. The book will also examine existing policies and proposed reforms in the developed world. Although this book addresses and has a general applicability to major water pollutants from agriculture (e.g., pesticides, pharmaceuticals, sediments, nutrients), it will focus on the sediment and nutrient pollution problem. The economic and scientific foundations for pollution management are best developed for these pollutants, and they are currently the top priorities of policy makers. Accordingly, the authors provide both highly salient and informative cases for developing concepts and methods of general applicability, with high profile examples such as the Chesapeake Bay, Lake Erie, and the Gulf of Mexico Dead Zone in the US; the Baltic Sea in Northern Europe; and Lake Taupo in New Zealand.

Download or read book Water pollution from agriculture a global review Executive summary written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-06-27 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water pollution is a global challenge that has increased in both developed and developing countries, undermining economic growth as well as the physical and environmental health of billions of people. Although global attention has focused primarily on water quantity, water-use efficiency and allocation issues, poor wastewater management has created serious water-quality problems in many parts of the world, worsening the water crisis. Global water scarcity is caused not only by the physical scar city of the resource but also by the progressive deterioration of water quality in many countries, reducing the quantity of water that is safe to use.The 2030 Agenda for Sustainable Development acknowledges the importance of water quality and includes a specific water quality target in Sustainable Development Goal (SDG) 6 .The 2030 Agenda for Sustainable Development is expected to strongly influence future policies and strategies and to ensure that the control of water pollution is elevated in international and national priorities.

Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Download or read book Water Implications of Biofuels Production in the United States written by National Research Council and published by National Academies Press. This book was released on 2008-02-09 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: National interests in greater energy independence, concurrent with favorable market forces, have driven increased production of corn-based ethanol in the United States and research into the next generation of biofuels. The trend is changing the national agricultural landscape and has raised concerns about potential impacts on the nation's water resources. To help illuminate these issues, the National Research Council held a colloquium on July 12, 2007 in Washington, DC. Water Implications of Biofuels Production in the United States, based in part on discussions at the colloquium, concludes that if projected future increases in use of corn for ethanol production do occur, the increase in harm to water quality could be considerable from the increases in fertilizer use, pesticide use, and soil erosion associated with growing crops such as corn. Water supply problems could also develop, both from the water needed to grow biofuels crops and water used at ethanol processing plants, especially in regions where water supplies are already overdrawn. The production of "cellulosic ethanol," derived from fibrous material such as wheat straw, native grasses, and forest trimmings is expected to have less water quality impact but cannot yet be produced on a commerical scale. To move toward a goal of reducing water impacts of biofuels, a policy bridge will likely be needed to encourage growth of new technologies, best agricultural practies, and the development of traditional and cellulosic crops that require less water and fertilizer and are optimized for fuel production.

Download or read book Drinking Water Supply and Agricultural Pollution written by G.J. Schrama and published by Springer Science & Business Media. This book was released on 2012-02-02 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural pollution (with nitrates and pesticides) is one of the biggest threats to drinking water resources. At many places regional and local water authorities, together with the water supply industry, are involved in preventive action aimed at farming practices. Three national case studies (Germany, The Netherlands, and the United Kingdom) analyse these efforts within the context of problematical national agricultural policy and the need to implement EU directives on water quality. Additional case studies cover the role of the European Union, while the same problem in a different setting is analysed for the United States. The central question of how national and European governments can reinforce the control capacity of the actors at the regional and local level, is treated from the theoretical perspective of the policy network approach.

Available in PDF, EPUB and Kindle. Book excerpt: How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.
