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.

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.

Download or read book Lake and Reservoir Restoration written by G. Dennis Cooke and published by Elsevier. This book was released on 2013-10-22 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake and Reservoir Restoration deals with the eutrophication process and the methods to protect, restore, and manage lakes and reservoirs. The most common in-lake techniques or procedures, plus nutrient diversion, are reviewed with regard to their scientific basis, methods of application, known effectiveness, feasibility, drawbacks, and costs. Areas for further research and development are also highlighted. This book is comprised of 16 chapters organized into four sections. After an introduction to the theory of the problem and the restoration technique, the discussion turns to the various restoration methods such as those used for physical and chemical control of nutrients. Diversion and advanced waste treatment, hypolimnetic withdrawal, and dilution and flushing are considered along with phosphorus precipitation and inactivation, sediment oxidation, sediment removal, and hypolimnetic aeration. Case studies and success stories are presented and the costs and potential negative impacts of the methods are examined. The following chapters focus on methods to control plant biomass, including artificial circulation, water-level drawdown, harvesting, biological control, and surface and sediment covers. A chapter on liming acidified lakes concludes this text. This monograph will be useful to professional limnologists and engineers, on-site lake or reservoir managers, and those who are interested in learning about the problems and management of lakes and reservoirs.

Download or read book Climate Rationality written by Jason S. Johnston and published by Cambridge University Press. This book was released on 2021-08-19 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most environmental statutes passed since 1970 have endorsed a pragmatic or 'precautionary' principle under which the existence of a significant risk is enough to trigger regulation. At the same time, targets of such regulation have often argued on grounds of inefficiency that the associated costs outweigh any potential benefits. In this work, Jason Johnston unpacks and critiques the legal, economic, and scientific basis for precautionary climate policies pursued in the United States and in doing so sheds light on why the global warming policy debate has become increasingly bitter and disconnected from both climate science and economics. Johnston analyzes the most influential international climate science assessment organizations, the US electric power industry, and land management and renewable energy policies. Bridging sound economics and climate science, this pathbreaking book shows how the United States can efficiently adapt to a changing climate while radically reducing greenhouse gas emissions.
Download or read book Modeling Phosphorus in the Environment written by David E. Radcliffe and published by CRC Press. This book was released on 2006-11-14 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite advances in modeling, such as graphical user interfaces, the use of GIS layers, and databases for developing input files, the approaches to modeling phosphorus (P) have not changed since their initial development in the 1980s. Current understanding of P processes has evolved and this new information needs to be incorporated into the current models. Filling this need, Modeling Phosphorus in the Environment describes basic approaches to modeling P, how the current models implement these approaches, and ways to improve them. The book sets the scene with a review of general approaches to modeling runoff and erosion, P in runoff, leaching of P, stream processes that affect P, and an examination of the important issue of model uncertainty. It describes state-of-the-science watershed-scale P transport models including dynamic semi-disturbed models, models of intermediate complexity, and two lumped models. Phosphorus Indexes (PIs) represent one end of the modeling spectrum and the book takes a comprehensive look at PIs developed in each state, and illustrates some of the problems encountered when incorporating PIs into farm-scale manure management software. The book discusses monitoring data, which is critical for calibrating models, and concludes with suggestions for improving the modeling of P. From researching mechanisms to applying regulations, the uses of phosphorus models have increased as our knowledge of the effects of phosphorus in the environment has increased. Drawing on contributions from experts, the book gives you the tools to select the model that best fits your needs.
Download or read book Governance Networks in Public Administration and Public Policy written by Christopher J. Koliba and published by CRC Press. This book was released on 2010-07-23 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: What do public administrators and policy analysts have in common? Their work is undertaken within networks formed when different organizations align to accomplish some kind of policy function. To be effective, they must find ways to navigate complexity and generate effective results. Governance Networks in Public Administration and Public Policy describes a variety of trends and movements that have contributed to the complexity of these systems and the challenges that must be faced as a result. Providing a theoretical and empirical foundation in governance networks, the book offers a conceptual framework for describing governance networks and provides a holistic way to conceive their construction. The text details the skills and functions of public administrators in the context of networked relationships and presents the theoretical foundations to analyze governance networks. It identifies the reforms and trends in governing that led to governance networks, explains the roles that various actors take on through networked relationships, highlights the challenges involved in the failure of networked activities, and illustrates how policy tools are mobilized by these relationships. Be a part of building governance networks 2.0! The author’s website contains support materials such as PowerPoint® presentations, writable case study templates, and other useful items related to building the field’s capacity to describe, evaluate, and design governance networks using the framework of this book.

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.
