Crop, livestock, and forestry productions systems are important sources and sinks of greenhouses gases, but estimates of the magnitude of gas fluxes are more uncertain than those for other economic sectors such as transportation and electricity generation. Recent improvements in process-level un-derstanding, modeling software, and observational data used for model testing have increased the accuracy of model predictions, but substantial uncertainty remains, particularly regarding the potential for different management practices to mitigate emissions. The chapters in this volume demonstrate that both simple methods and complex models have strengths and limitations depending on stake-holder interest, scale of application, and other factors. Future improvement can be facilitated by or-ganizing model input and testing data into web-accessible databases and by making model algorithms more available and transparent.

This book provides standards and guidelines for quantifying greenhouse gas emissions and removals in smallholder agricultural systems and comparing options for climate change mitigation based on emission reductions and livelihood trade-offs. Globally, agriculture is directly responsible for about 11% of annual greenhouse gas (GHG) emissions and induces an additional 17% through land use change, mostly in developing countries. Farms in the developing countries of sub-Saharan Africa and Asia are predominately managed by smallholders, with 80% of land holdings smaller than ten hectares. However, little to no information exists on greenhouse gas emissions and mitigation potentials in smallholder agriculture. Greenhouse gas measurements in agriculture are expensive, time consuming, and error prone, challenges only exacerbated by the heterogeneity of smallholder systems and landscapes. Concerns over methodological rigor, measurement costs, and the diversity of approaches, coupled with the demand for robust information suggest it is germane for the scientific community to establish standards of measurements for quantifying GHG emissions from smallholder agriculture. Standard guidelines for use by scientists, development organizations will help generate reliable data on emissions baselines and allow rigorous comparisons of mitigation options. The guidelines described in this book, developed by the CGIAR Research Program on Climate Change, Agriculture, and Food Security (CCAFS) and partners, are intended to inform anyone conducting field measurements of agricultural greenhouse gas sources and sinks, especially to develop IPCC Tier 2 emission factors or to compare mitigation options in smallholder systems.

Human-induced climate change is an important environmental issue worldwide, as scientific studies increasingly demonstrate that human activities are changing the Earth's climate. Even if dramatic reductions in emissions were made today, some human-induced changes are likely to persist beyond the 21st century. The Kyoto Protocol calls for emissions reporting that separates out management-induced changes in greenhouse gases from those changes caused by indirect human effects (e.g., carbon dioxide fertilization, nitrogen deposition, or precipitation changes), natural effects, and past practices on forested agricultural lands. This book summarizes a September 2003 workshop where leaders from academia, government and industry came together to discuss the current state of scientific understanding on quantifying direct human-induced change in terrestrial carbon stocks and related changes in greenhouse gas emissions and distinguishing these changes from those caused by indirect and natural effects.

Soil carbon sequestration can play a strategic role in controlling the increase of CO2 in the atmosphere and thereby help mitigate climatic change. There are scientific opportunities to increase the capacity of soils to store carbon and remove it from circulation for longer periods of time. The vast areas of degraded and desertified lands throughout the world offer great potential for the sequestration of very large quantities of carbon. If credits are to be bought and sold for carbon storage, quick and inexpensive instruments and methods will be needed to monitor and verify that carbon is actually being added and maintained in soils. Large-scale soil carbon sequestration projects pose economic and social problems that need to be explored. This book focuses on scientific and implementation issues that need to be addressed in order to advance the discipline of carbon sequestration from theory to reality. The main issues discussed in the book are broad and cover aspects of basic science, monitoring, and implementation. The opportunity to restore productivity of degraded lands through carbon sequestration is examined in detail. This book will be of special interest to professionals in agronomy, soil science, and climatology.

Global climate change is a natural process that currently appears to be strongly influenced by human activities, which increase atmospheric concentrations of greenhouse gases (GHG). Agriculture contributes about 20% of the world’s global radiation forcing from carbon dioxide, methane and nitrous oxide, and produces 50% of the methane and 70% of the nitrous oxide of the human-induced emission. Managing Agricultural Greenhouse Gases synthesizes the wealth of information generated from the GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) effort with contributors from a variety of backgrounds, and reports findings with important international applications. Frames responses to challenges associated with climate change within the geographical domain of the U.S., while providing a useful model for researchers in the many parts of the world that possess similar ecoregions Covers not only soil C dynamics but also nitrous oxide and methane flux, filling a void in the existing literature Educates scientists and technical service providers conducting greenhouse gas research, industry, and regulators in their agricultural research by addressing the issues of GHG emissions and ways to reduce these emissions Synthesizes the data from top experts in the world into clear recommendations and expectations for improvements in the agricultural management of global warming potential as an aggregate of GHG emissions

As the United States moves to a low-carbon economy in order to combat global warming, credits for reducing carbon dioxide emissions will increasingly become a commodity that is bought and sold on the open market. Farmers and other landowners can benefit from this new economy by conducting land management practices that help sequester carbon dioxide, creating credits they can sell to industry to "offset" industrial emissions of greenhouse gases. This guide is the first comprehensive technical publication providing direction to landowners for sequestering carbon and information for traders and others who will need to verify the sequestration. It will provide invaluable direction to farmers, foresters, land managers, consultants, brokers, investors, regulators, and others interested in creating consistent, credible greenhouse gas offsets as a tradable commodity in the United States. The guide contains a non-technical section detailing methodologies for scoping of the costs and benefits of a proposed project, quantifying offsets of various sorts under a range of situations and conditions, and verifying and registering the offsets. The technical section provides specific information for quantifying, verifying, and regulating offsets from agricultural and forestry practices.

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.

Soil carbon sequestration and preservation of present stocks reduces net global greenhouse gas emission and can contribute significantly to both Nordic and international goals of limiting serious climate change. In order to achieve this, sustainable use of soil resources, better soil and water management practices, and restoration of degraded soils is needed. Protection and restoration of soil organic carbon are also key solutions to many of the most pressing global challenges facing mankind today. Highlighting the importance of the soil and the multiple benefits of soil organic carbon sequestration has never been more needed than now.
