Available in PDF, EPUB and Kindle. Book excerpt: Nutrient enrichment of water resources by inputs of nitrogen and phosphorus, which can lead to eutrophication is still a water quality problem in agriculturally dominated watersheds around the world. Internationally, wetlands both constructed and natural are increasingly being used to help reduce both point and non-point source nutrient and contaminant loss from agricultural practices. This publication contains papers presented at the international symposium on "Nutrient Management in Agricultural Watersheds: A Wetlands Solution," which was held during May, 2004 in Wexford, Ireland. The symposium was the result of an international collaboration between the Teagasc Research Centre, Johnstown Castle, Ireland, National Parks and Wildlife, Department of Environment, Heritage and Local Government, Ireland and the Soil and Water Science Department at the University of Florida, Gainesville, USA. These proceedings cover aspects of water quality within agricultural watersheds; management practices to mitigate contaminant and nutrient loss from agriculture; wetland biogeochemistry; wetland functions and values within agricultural dominated landscapes; case studies of wetlands used to retain nutrient and contaminant loss from agriculture; and finally some management and policy issues concerning wetlands are presented. This book provides a good interdisciplinary synthesis of international experiences both in Europe and the USA on the use of wetlands within agricultural watersheds.

This book was released on 2020-12-04 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.

Available in PDF, EPUB and Kindle. Book excerpt: Using the Chesapeake Bay as a case study, Agriculture and Phosphorus Management discusses the impact and management of phosphorus in watersheds. Although urban and other sources contribute phosphorus to the Bay, the papers presented focus on how its role in agriculture impacts water quality. They review the new guidelines and legislation slated for implementation by 2002 directed towards sustainable nutrient management and strategies for implementing them. Phosphorus, an essential element for plant and animal growth, has long been recognized as necessary to eliminate deficiencies and to maintain profitable crop and livestock production. It can increase the biological productivity of surface waters by accelerating eutrophication. Human activities accelerate the rate of eutrophication - principally by increasing the rate at which phosphorus enters the aquatic system. Written by experts from a range of disciplines Agriculture and Phosphorus Management provides a deeper understanding of the diverse, dynamic, and complex factors controlling the impact of agricultural phosphorus management on production and water quality. Each contributor addresses the questions: what do we know, what do we still need to know, where are the major gaps in our knowledge, and how does the information relate to phosphorus management strategies in the Bay Watershed, and other watersheds? As a result this series of papers provides a unique collection of information of regional, national, and international significance and gives prioritized phosphorus management options for not only the Chesapeake Bay Watershed, but for watersheds around the world.
Download or read book Nutrient Control Actions for Improving Water Quality in the Mississippi River Basin and Northern Gulf of Mexico written by National Research Council and published by National Academies Press. This book was released on 2009-07-13 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large area of coastal waters in the northern Gulf of Mexico experiences seasonal conditions of low levels of dissolved oxygen, a condition known as hypoxia. Excess discharge of nutrients into the Gulf of Mexico from the Mississippi and Atchafalaya rivers causes nutrient overenrichment in the gulf's coastal waters and stimulates the growth of large algae blooms. When these algae die, the process of decomposition depletes dissolved oxygen from the water column and creates hypoxic conditions. In considering how to implement provisions of the Clean Water Act to strengthen nutrient reduction objectives across the Mississippi River basin, the U.S. Environmental Protection Agency (EPA) requested advice from the National Research Council. This book represents the results of the committee's investigations and deliberations, and recommends that the EPA and U.S. Department of Agriculture should jointly establish a Nutrient Control Implementation Initiative to learn more about the effectiveness of actions meant to improve water quality throughout the Mississippi River basin and into the northern Gulf of Mexico. Other recommendations include how to move forward on the larger process of allocating nutrient loading caps-which entails delegating responsibilities for reducing nutrient pollutants such as nitrogen and phosphorus-across the basin.

Available in PDF, EPUB and Kindle. Book excerpt: If you work in the water quality management field, you know the challenges of monitoring and controlling pollutants in our water supply. The increasing problem of agricultural nonpoint source pollution requires complex solutions. Agricultural Nonpoint Source Pollution: Watershed Management and Hydrology covers the latest techniques and methods of managing large watershed areas, with an emphasis on controlling non-point source pollution, especially from agricultural run-off. Written by leading experts, the book includes topics such as: nitrate and phosphorus pollution, pesticide contamination, erosion and sedimentation, water-table management, and watershed management. The authors discuss the effects of agricultural run-off - one of the most intransigent problems now faced by environmental engineers and hydrologists. They explore each issue with an eye towards the integrated management of water quality and water resources over a defined area or region. This single-source reference gives you a complete understanding of the whats, whys, and hows of nonpoint source pollution - and more importantly of how to monitor and manage it. Agricultural Nonpoint Source Pollution: Watershed Management and Hydrology provides a broad but detailed overview that helps you to comprehend the intricacies of the problem and puts you on the path to finding the answers.
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.

Available in PDF, EPUB and Kindle. Book excerpt: The diffuse runoff of agricultural nutrients, also called agricultural nonpoint source pollution (NPS), is a widespread threat to freshwater resources. Despite decades of research into the processes of eutrophication and agricultural nutrient management, social, economic, and political barriers have slowed progress towards improving water quality. A critical challenge to managing agricultural NPS pollution is motivating landowners to act against their individual farm production incentives in response to distant ecological impacts. The complexity of governing the social-ecological system requires improved understanding of how policy shapes farmer behavior to improve the state of water quality. This dissertation contributes both theoretically and empirically to NPS pollution governance by examining the impacts of water quality policy design on farmer nutrient management decision making and behavior. In the first study, I theoretically contextualize the issue of agricultural NPS pollution in the broader discussion of environmental public goods dilemmas to suggest that an increased focus on the link between policy and behavior can improve sustainable resource management. I propose two empirical approaches to study the policy-behavior link in environmental public goods dilemmas: 1) explicit incorporation of social psychological and behavioral variables and 2) utilization of actor mental models, or perceptions of the world that guide decision making, to identify behavioral drivers and outcomes. In the second and third studies, I then use these approaches to examine how water quality policies for agricultural NPS collectively change farmer behavior to reduce nutrient emissions. The second chapter uses a quantitative, survey-based approach to examine the relationship between mandatory policy design and behavior change in New Zealand. I find that a shift to mandatory policy is not immediately associated with increased adoption of nutrient management practices, but the mandatory policy design is important for potential future behavior change and long-term policy support. In the third study, I combine qualitative methodology with network analysis of qualitative data to examine a spectrum of agricultural NPS pollution policies in Vermont, USA and Taupo and Rotorua, New Zealand. I use farmer mental models to examine behavior change within each of the regions, the perceived drivers of behavior change and perceived outcomes of the policy. In this study, farmers across all three regions cite mandatory water policy as a key behavioral driver, but in each region, policy design interacts with the social-ecological context to produce distinct patterns of behaviors and perceived outcomes. Taken together, this dissertation demonstrates that agricultural NPS pollution policy design must consider the interactions between policy and other social-ecological behavioral drivers in order to achieve long term water quality improvements.
