Much attention has been given to above ground biomass and its potential as a carbon sink, but in a mature forest ecosystem 40 to 60 percent of the stored carbon is below ground. As increasing numbers of forests are managed in a wide diversity of climates and soils, the importance of forest soils as a potential carbon sink grows. The Potential of U.S. Forest Soils to Sequester Carbon and Mitigate the Greenhouse Effect provides researchers and policy makers with an understanding of soil processes and their relation to carbon dynamics, as well as strategies to monitor and techniques to measure forest soil carbon. It covers the effects of management on soils in a wide range of forest ecosystems together with policy options that are effective and benefit both the forest community and the over all environment. This valuable reference provides forest managers, urban planners, land owners, policy makers, and the general public with guidance that will allow for a holistic approach to land management, environmental quality, and improved forest productivity.

This collection represents a unique set of essays on the role of theory in shaping the practice of medicine across disciplinary boundaries. In the context of this volume, "theory” relates to the conceptual models, frameworks, knowledge representations, metaphors and analogies that inform the problem-solving efforts of practitioners seeking to develop novel dialogues both within and across disciplinary boundaries. Contributors to this volume include computational scientists, chemists, medical researchers, biologists and philosophers, all drawing on personal experience in their respective fields to produce a genuinely interdisciplinary range of perspectives on the common theme of theory in medical thinking and multidisciplinary research practice. * Selected and edited papers from the 10th North American Forest Soils Conference held in Saulte Ste. Marie, Ontario, Canada, July 20-24, 2003 * A unique spin-off from Elsevier's highly regarded journal, Forest Ecology and Management * An estimated 400 pages of the latest findings in forest soil ecology from the most prominent researchers in the field

In 2008, agricultural greenhouse gas sources accounted for about 6% of total U.S. greenhouse gas emissions. The U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2008 was developed to provide a comprehensive assessment of the contribution of U.S. agriculture and forestry to greenhouse gas emissions and carbon sequestration. It provides extensive, in-depth emissions and sinks estimates for livestock, cropland, and forests, as well as energy consumption in livestock and cropland agriculture. Estimates are provided at State, regional, and national scales, categorized by land ownership and management practices where possible. Charts and tables. This is a print on demand edition of an important, hard-to-find publication.

This report assesses the potential of U.S. cropland to sequester carbon, concluding that properly applied soil restorative processes and best management practices can help mitigate the greenhouse effect by decreasing the emissions of greenhouse gases from U.S. agricultural activities and by making U.S. cropland a major sink for carbon sequestration. Topics include: Describe the greenhouse processes and global tends in emissions as well as the three principal components of anthropogenic global warming potential Present data on U.S. emissions and agriculture's related role Examines the soil organic carbon (SOC) pool in soils of the U.S. and its loss due to cultivation Provides a reference for the magnitude of carbon sequestration potential Analyzes the primary processes governing greenhouse gas emission from the pedosphere Establishes a link between SOC content and soil quality Outlines strategies for mitigating emissions from U.S. cropland Discusses soil erosion management Assesses the potential of using cropland to create biomass for direct fuel to produce power Details the potential for sequestering carbon by intensifying prime agricultural land The Potential of U.S. Cropland to Sequester Carbon and Mitigate the Greenhouse Effect provides an exceptional framework for the adoption of science-based management methods on U.S. cropland, encouraging appropriate agricultural practices for the sustainable use of our natural resources and the improvement of our nation's environment.

Grazing lands represent the largest and most diverse land resource-taking up over half the earth's land surface. The large area grazing land occupies, its diversity of climates and soils, and the potential to improve its use and productivity all contribute to its importance for sequestering C and mitigating the greenhouse effect and other conditions brought about by climate change. The Potential of U.S. Grazing Lands to Sequester Carbon and Mitigate the Greenhouse Effect gives you an in-depth look at this possibility.

Evidence has been mounting for some time that intensive row-crop agriculture as practiced in developed countries may not be environmentally sustainable, with concerns increasingly being raised about climate change, implications for water quantity and quality, and soil degradation. This volume synthesizes two decades of research on the sustainability of temperate, row-crop ecosystems of the Midwestern United States. The overarching hypothesis guiding this work has been that more biologically based management practices could greatly reduce negative impacts while maintaining sufficient productivity to meet demands for food, fiber and fuel, but that roadblocks to their adoption persist because we lack a comprehensive understanding of their benefits and drawbacks. The research behind this book, based at the Kellogg Biological Station (Michigan State University) and conducted under the aegis of the Long-term Ecological Research network, is structured on a foundation of large-scale field experiments that explore alternatives to conventional, chemical-intensive agriculture. Studies have explored the biophysical underpinnings of crop productivity, the interactions of crop ecosystems with the hydrology and biodiversity of the broader landscapes in which they lie, farmers' views about alternative practices, economic valuation of ecosystem services, and global impacts such as greenhouse gas exchanges with the atmosphere. In contrast to most research projects, the long-term design of this research enables identification of slow or delayed processes of change in response to management regimes, and allows examination of responses across a broader range of climatic variability. This volume synthesizes this comprehensive inquiry into the ecology of alternative cropping systems, identifying future steps needed on the path to sustainability.

This book reviews the state of agricultural climate change mitigation globally, with a focus on identifying the feasibility, opportunities and challenges for achieving mitigation among smallholder farmers. The purpose is ultimately to accelerate efforts towards mitigating land-based climate change. While much attention has been focused on forestry for its reputed cost-effectiveness, the agricultural sector contributes about ten to twelve per cent of emissions and has a large technical and economic potential for reducing greenhouse gases. The book does not dwell on the science of emissions reduction, as this is well covered elsewhere; rather, it focuses on the design and practical implementation of mitigation activities through changing farming systems. Climate Change Mitigation and Agriculture includes chapters about experiences in developed countries, such as Canada and Australia, where these efforts also have lessons for mitigation options for smallholders in poorer nations, as well as industrialising countries such as Brazil and China. A wide range of agroecological zones and of aspects or types of farming, including livestock, crops, fish farming, fertilizer use and agroforestry, as well as economics and finance, is included. The volume presents a synthesis of current knowledge and research activities on this emerging subject. Together the chapters capture an exciting period in the development of land-based climate change mitigation as attention is increasingly focused on agriculture's role in contributing to climate change.
