The Universal Soil Loss Equation (USLE) enables planners to predict the average rate of soil erosion for each feasible alternative combination of crop system and management practices in association with a specified soil type, rainfall pattern, and topography. When these predicted losses are compared with given soil loss tolerances, they provide specific guidelines for effecting erosion control within specified limits. The equation groups the numerous interrelated physical and management parameters that influence erosion rate under six major factors whose site-specific values can be expressed numerically. A half century of erosion research in many States has supplied information from which at least approximate values of the USLE factors can be obtained for specified farm fields or other small erosion prone areas throughout the United States. Tables and charts presented in this handbook make this information readily available for field use. Significant limitations in the available data are identified.

This book gathers recent international research on the association between aggressive rainfall and soil loss and landscape degradation. Different contributions explore these complex relationships and highlight the importance of the spatial patterns of precipitation intensity on land flow under erosive storms, with the support of observational and modelling data. This is a large and multifaceted area of research of growing importance that outlines the challenge of protecting land from natural hazards. The increase in the number of high temporal resolution rainfall records together with the development of new modelling capabilities has opened up new opportunities for the use of large-scale planning and risk prevention methods. These new perspectives should no longer be considered as an independent research topic, but should, above all, support comprehensive land use planning, which is at the core of environmental decision-making and operations. Textbooks such as this one demonstrate the significance of how hydrological science can enable tangible progress in understanding the complexity of water management and its current and future challenges.

This book analyses climate change influences on rainfall erosivity and soil erosion across Central Asia, provides an overview (past and projections) on the Central Asian countries where projected changes in rainfall erosivity and erosivity density are the greatest, and discusses the potential impacts on the environment across the region. This analysis is accomplished primarily using the RUSLE model with past and future climate projections, spatiotemporal variations of rainfall erosivity and soil erosion based on WorldClim, and Coupled Model Intercomparison Project Phase 5 (CMIP5) climate models (for Central Asia and separately Kazakhstan). The relationship between precipitation characteristics and erosion has been well established, but spatial and temporal projections of future rainfall erosivity in a changing climate in Central Asia have not been published significantly. Therefore, assessing rainfall erosivity and its consequences can assist specialists and researchers in achieving the best practices for soil conservation. The result of this type of research is all-encompassing, and may reflect normal variations in other parts of the world (for example, the arid and semi-arid regions) and is inherently limited to the Central Asian region.
