Soil degradation has serious global impacts on agronomic, economic, and sociopolitical conditions, however, statistics regarding the degree of these impacts has been largely unreliable. This book aims to standardize the methodology for obtaining reliable and objective data on soil degradation. It will also identify and develop criteria for assessing the severity of soil degradation, providing a realistic scenario of the problem.

This new edition of Soil Erosion Research Methods retains the themes and layout of the first edition. However, most chapters have been revised and some additional chapters have been added. There are new chapters on modeling wind and water erosion. Extensive revisions and updating have been done in chapters dealing with assessment of erosivity and erodibility, erosion, crop productivity, measuring sediment yield from river basins and field plot techniques. There is extensive updating of current statistics on the global magnitude of soil erosion by water and wind and on denudation rates. Several new authors have made significant improvements in revising and updating available information.

This publication deals with soil erosion and sedimentation. Soil erosion and associated sediment deposition are natural landscape-forming processes that can be greatly accelerated by human intervention through deforestation, overgrazing, and non-sustainable farming practices. Soil erosion and sedimentation may not only cause on-site degradation of the natural resource base, but also off-site problems— downstream sediment deposition in fields, floodplains and water bodies, water pollution, eutrophication and reservoir siltation, etc. —with serious environmental and economic impairment. There is an urgent need for accurate information to quantify the problem and to underpin the selection of effective soil-conservation technologies and sedimentation-remediation strategies, including assessment of environmental and economic impacts. Existing classical techniques to document soil erosion are capable of meeting some of these needs, but they all possess important limitations. The quest for alternative techniques for assessing soil erosion, to complement existing methods, directed attention to the use of environmental radionuclides, in particular fallout as tracers to quantify rates and establish patterns of soil redistribution within the landscape. The concept of a project on the use of environmental radionuclides to quantify soil redistribution was first formulated at an Advisory Group Meeting convened in Vienna, April 1993, by the International Atomic Energy Agency (IAEA).

This study was designed to validate the use of visible and near infrared spectroscopy for characterizing soil properties and develop a protocol based on geographical information systems (GIS), spatial analysis and satellite remote sensing for modeling attributes of land degradation in a tropical agricultural landscape. The study had three main objectives: to develop and validate spectral models for predicting soil properties, to map the spatial distribution of soil organic carbon using (SOC) using a GIS-based spatial model and to test the use of ASTER satellite data for interpolating measurements of soil organic carbon in the landscape. Data were collected in two adjunct districts of Siaya and Vihiga in western Kenya.

From the presentations and discussions a set of conclusions is drawn concerning our ability to feed the world population and the steps which must be taken to ensure that we achieve this aim. This book is essential reading for practitioners and students of agronomy, forestry, soil science and ecology concerned with natural resource management, and presents information which will also be of value to economists, policy makers and environmentalists with an interest in global issues.

Since carbon sequestration in soils reduces the amount of carbon available to the atmosphere, the Kyoto Protocols have heightened interest in soil carbon pools and their effect on carbon fluxes. Assessment Methods for Soil Carbon addresses many of the questions related to the measurement, monitoring, and verification of organic and inorganic carbon in soils. The major topics covered are: carbon pools; soil sampling and preparation, analytical techniques for soil carbon; soil erosion and sedimentation; remote sensing, GIS and modeling; procedures for scaling carbon data from point and local measurements to regional and even national scales; and economic and policy issues. In Assessment Methods for Soil Carbon, leading researchers show that we now have the ability to measure, monitor, and verify changes to soil carbon. The book establishes the need for standardized methods that can be used by anyone, and helps us better understand the link between the pedosphere (soils) and the atmosphere. It also shows the importance of developing links between the economics of carbon sequestration and the amounts sequestered, and highlights the need for scientists and policy makers to interact to ensure that policies fit within the scope of present technologies.
