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 Manure Use for Fertilizer and for Energy written by James M. MacDonald and published by DIANE Publishing. This book was released on 2010 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 5% of all U.S. cropland is currently fertilized with livestock manure. Expanded environmental regulation through nutrient management plans will likely lead to wider use of manure on cropland, at higher production costs, but with only modest impacts on commodity demand, or farm structure. While current use is limited, expanded gov¿t. support could lead to a substantial increase in manure use as a feedstock. However, current energy processes are unlikely to compete with fertilizer uses of manure, because they leave fertilizer nutrients as residues, in more marketable form, and because manure-to-energy projects will be most profitable in regions where raw manure is in excess supply, with the least value as fertilizer.

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 The California Nitrogen Assessment written by Thomas P. Tomich and published by Univ of California Press. This book was released on 2016-06-14 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is indispensable to all life on Earth. However, humans now dominate the nitrogen cycle, and nitrogen emissions from human activity have real costs: water and air pollution, climate change, and detrimental effects on human health, biodiversity, and natural habitats. Too little nitrogen limits ecosystem processes, while too much nitrogen transforms ecosystems profoundly. The California Nitrogen Assessment is the first comprehensive account of nitrogen flows, practices, and policies for California, encompassing all nitrogen flows—not just those associated with agriculture—and their impacts on ecosystem services and human wellbeing. How California handles nitrogen issues will be of interest nationally and internationally, and the goal of the assessment is to link science with action and to produce information that affects both future policy and solutions for addressing nitrogen pollution. This book also provides a model for application of integrated ecosystem assessment methods at regional and state (subnational) levels.

Download or read book Improving Potassium Recommendations for Agricultural Crops written by T. Scott Murrell and published by Springer. This book was released on 2022 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book highlights concepts discussed at two international conferences that brought together world-renowned scientists to advance the science of potassium (K) recommendations for crops. There was general agreement that the potassium recommendations currently in general use are oversimplified, outdated, and jeopardize soil, plant, and human health. Accordingly, this book puts forward a significantly expanded K cycle that more accurately depicts K inputs, losses and transformations in soils. This new cycle serves as both the conceptual basis for the scientific discussions in this book and a framework upon which to build future improvements. Previously used approaches are critically reviewed and assessed, not only for their relevance to future enhancements, but also for their use as metrics of sustainability. An initial effort is made to link K nutrition in crops and K nutrition in humans. The book offers an invaluable asset for graduate students, educators, industry scientists, data scientists, and advanced agronomists.
