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.
Download or read book Multifunctional Wetlands written by Nidhi Nagabhatla and published by Springer. This book was released on 2017-10-25 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how natural or constructed wetlands can be used to reduce pollution of freshwater and coastal ecosystems, while still preserving their biodiversity and ecological functions. Through a series of case histories described in 10 chapters in the monograph, the readers will gain an understanding of the opportunities, as well as the challenges associated with reducing point and non-point source pollution using natural, restored or constructed wetlands. The target audience will be water practitioners involved in projects utilizing integrated watershed management approaches to pollution abatement, as well as researchers who are designing projects focused on this topic.

Download or read book Hypoxia in the Northern Gulf of Mexico written by Virginia H. Dale and published by Springer Science & Business Media. This book was released on 2010-04-12 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot s- port marine life, generally manifests itself in the spring. Since marine species either die or ee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational shing in the Gulf. Since 2001, the hypoxic zone has averaged 2 1 16,500 km during its peak summer months , an area slightly larger than the state 2 2 of Connecticut, and ranged from a low of 8,500 km to a high of 22,000 km . To address the hypoxia problem, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (or Task Force) was formed to bring together represen- tives from federal agencies, states, and tribes to consider options for responding to hypoxia. The Task Force asked the White House Of ce of Science and Technology Policy to conduct a scienti c assessment of the causes and consequences of Gulf hypoxia through its Committee on Environment and Natural Resources (CENR).

Download or read book The Atchafalaya River Basin written by Bryan P. Piazza and published by Texas A&M University Press. This book was released on 2014-02-25 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this comprehensive, one-volume reference, Nature Conservancy scientist Bryan P. Piazza poses five key questions: —What is the Atchafalaya River Basin? —Why is it important? —How have its hydrology and natural habitats been managed? —What is its current state? —How do we ensure its survival? For more than five centuries, the Atchafalaya River Basin has captured the flow of the Mississippi River, becoming its main distributary as it reaches the Gulf of Mexico in south Louisiana. This dynamic environment, comprising almost a million acres of the lower Mississippi Alluvial Valley and Mississippi River Deltaic Plain, is perhaps best known for its expansive swamp environments dominated by baldcypress, water tupelo, and alligators. But the Atchafalaya River Basin contains a wide range of habitats and one of the highest levels of biodiversity on the North American continent. Piazza has compiled and synthesized the body of scientific knowledge for the Atchafalaya River Basin, documenting the ecological state of the basin and providing a baseline of understanding. His research provides a crucial resource for future planning. He evaluates some common themes that have emerged from the research and identifies important scientific questions that remain unexplored.
Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-09-10 with total page 448 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 From the Corn Belt to the Gulf written by Joan I Nassauer and published by Taylor & Francis. This book was released on 2010-09-30 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrients from farms in the Mississippi River Basin are the leading cause of the Gulf of Mexico‘s 'Dead Zone,' a 5,000 to 7,000 square mile region where declining oxygen levels are threatening the survival of marine life. From the Corn Belt to the Gulf explores how new agricultural policy can help alleviate this problem, and at the same time improve water quality overall, enhance biodiversity, improve the quality of life for the people who live and work in Corn Belt communities, and relieve downstream flooding. The themes of the book are the far-reaching environmental impacts of Corn Belt agriculture, including associated economic and social effects at multiple spatial scales - and the potential for future agricultural policy to address those impacts through changes in agricultural landscapes and practices. We know that the environmental 'footprint' of Corn Belt agriculture extends beyond farmland and adjacent lakes and streams to groundwater, rivers, cities downstream, into the Gulf of Mexico, and, ultimately, to global oceanic and atmospheric systems. And we acknowledge that agricultural policies, including commodity support payments, have economic impacts at the national and international levels. Pressing negotiations with America‘s trade partners, along with increasing societal attention to both the costs and environmental effects of current agricultural policy, are creating momentum for policy change. From the Corn Belt to the Gulf presents innovative, integrated assessments of the agriculture and ecological systems in the Mississippi River Basin along with studies of local Iowa agricultural watersheds. Contributors from multiple academic and professional disciplines discuss how agricultural policies have contributed to current environmental conditions, and, in what the authors term 'alternative futures' for agricultural landscapes, envision how new policy can help achieve more beneficial patterns.
