Book Description
Provides a unique and comprehensive assessment of soil erosion throughout Europe, an important aspect to control and manage if landscapes are to be sustained for the future. Written in two parts, Soil Erosion in Europe primarily focuses on current issues, area specific soil erosion rates, on and off-site impacts, government responses, soil conservation measures, and soil erosion risk maps. The first part overviews the erosion processes and the problems encountered within each European country, whilst the second section takes a cross-cutting theme approach. Based on an EU-funded project that has been running for four years with erosion scientists from 19 countries Reviews contemporary erosion processes and rates on arable and rangeland in Europe Looks at current issues, such as socio-economic drivers, controlling factors specific to the country and changes in land use

Book Description
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.

Book Description
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.

Book Description
Eutrophication, caused by phosphorus enrichment, is not a new environmental problem. The persistence of eutrophication in an era when many point-source phosphorus inputs have been curtailed has turned the focus of attention to agricultural phosphorus. A workshop was held in Ireland in 1995 to discuss factors controlling phosphorus losses to water from agriculture. This book presents the proceedings of the workshop and consists of 18 chapters by the invited speakers and three chapters with the 45 poster papers displayed at the workshop.

Book Description
Based on the proceedings of the annual conference of the Institute of British Geographers, held at Coventry Polytechnic in January 1989. The papers in this volume give a comprehensive overview of soil erosion, covering topics in erosion processes, assessment and prediction and policy. There are several general review articles as well as more focused contributions from geomorphology, computing, agronomy, soil science, sedimentology, geology and agricultural economics.
