This book collates, reviews and synthesizes information on how soil organic carbon (SOC) stocks differ among major terrestrial biomes of the U.S.A. Information on soil inorganic carbon (SIC) stocks for different terrestrial biomes of the U.S.A. will also be presented. The book deliberates options for increasing SOC stocks and enhancing SOC sequestration in terrestrial biomes by soil and land-use management practices. It concludes with an overview of terrestrial biomes of the U.S.A. where targeted soil and land-use management practices may result in the greatest increases in SOC stocks and enhancements in SOC sequestration.

To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

This book will collate, review and synthesize information on how Organic Agriculture (OA) practices affect and are affected by climate change, in comparison to the more widely used conventional agricultural practices. Pros and cons of OA practices will be discussed separately for croplands, pasture lands, mixed livestock cropping systems, vegetable fields, fruit and tree orchards, and vineyards. The book concludes with an overview on how conventional and OA practices can be prudently and discriminately combined to identify and adopt climate-resilient agro-ecosystems under site-specific conditions.

Discover the latest available knowledge on ways to reduce CO2 in the atmosphere! The problem of quickly mounting CO2 emissions in the fast-developing Latin American region was addressed in a symposium held in Piracicaba, Brazil, in June 2004. Carbon Sequestration in Soils of Latin America presents the latest available knowledge in soil C sequestration and improved land and soil management which can also lead to other positive effects, such as greater fertility of soil and higher crop yields. This text, in easy-to-understand language, comprehensively reviews ways to best transform various soils from being a source of carbon released into the atmosphere to become a sink for carbon absorption. Carbon Sequestration in Soils of Latin America presents a full-rounded explanation of this information in four sections. The first section gives detailed background information about the region, its climate, and the differing soils, along with basic concepts behind the science. The second section describes recommended management practices and rates of soil C sequestration. The third section thoroughly deals with methods of assessment of soil C. The last section provides a summary of recommendations for further research and development. The book is extensively referenced and contains numerous figures, tables, and photographs. Topics in Carbon Sequestration in Soils of Latin America include: soil eco-regions and principal biomes of Latin America soil carbon stock in principal ecosystems of Latin America rates of carbon sequestration in different eco-regions for predominant land use and management the role of the Amazon region in mitigating climate change the importance of tropical savannas of Latin America in mitigating global warming innovative methods of assessment of soil carbon pool trading carbon credits designing pilot soil carbon sequestration projects potential of soil carbon sequestration in Latin America priorities and recommendations for future research Carbon Sequestration in Soils of Latin America is a comprehensive, essential resource for land managers, policymakers, educators, students, and researchers.

During the last decades, soil organic carbon (SOC) attracted the attention of a much wider array of specialists beyond agriculture and soil science, as it was proven to be one of the most crucial components of the earth’s climate system, which has a great potential to be managed by humans. Soils as a carbon pool are one of the key factors in several Sustainable Development Goals, in particular Goal 15, “Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification and halt and reverse land degradation and halt biodiversity loss” with the SOC stock being explicitly cited in Indicator 15.3.1. This technical manual is the first attempt to gather, in a standardized format, the existing data on the impacts of the main soil management practices on SOC content in a wide array of environments, including the advantages, drawbacks, and constraints. This manual presents different sustainable soil management (SSM) practices at different scales and in different contexts, supported by case studies that have been shown with quantitative data to have a positive effect on SOC stocks and successful experiences of SOC sequestration in practical field applications. Volume 2 includes a description of hot spots of SOC stocks. This manual defines hot spots of SOC as areas that represent a proportionally little of the global land surface but on which SOC storage is highly effective; bright spots as large land areas with low SOC stocks per km2 that represent a potential for further carbon sequestration.

Better Manage Soil C for Improved Soil Quality In the United States, soil has fueled the availability of abundant, safe food, thus underpinning economic growth and development. In the future we need to be more vigilant in managing and renewing this precious resource by replacing the nutrients and life-sustaining matter that we remove for
