This book was released on 2019-04-29 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides diverse information and critical know-how to implement appropriate methodology and cost-efficient monitoring and evaluation systems better suited to assess the impacts of soil conservation and wastershed multi-sectoral development activities. It draws on a worldwide experience of specialists and a large array of ground-truthing projects and programmes. This book will meet its objective if it contributes to convince financing institutions and project managers that integrated watershed management activities have the potential to generate highly desirable impacts for the society at large, which have to be accurately measured by adequate M&E systems.

Download or read book Watershed Erosion Processes written by Tongxin Zhu and published by Springer Nature. This book was released on 2021-09-29 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is a fundamental study of watershed erosion and runoff processes. It utilizes decades of soil erosion data to take a comprehensive and balanced approach in covering various watershed erosion processes. While there are many works on soil erosion and conservation, this book fills the gaps in previously published research by focusing more on mass movement, gully erosion, soil piping/tunnel erosion, and the spatial interactions of different erosion processes. Additionally, the book examines erosion processes in extreme rainfall events, something typically absent in short-term studies but discussed in detail here as the book draws on 60 years of research and observations, including 30 years of the author's own investigations of erosion under a wide range of rainfall conditions. The book is divided into 3 parts, and is intended for soil erosion researchers and practitioners, and postgraduate students studying soil erosion and water conservation. Part 1 opens with a comprehensive and critical review of existing literature on soil erosion processes, discusses this book's place among existing literature, and examines the major erosion processes (rainwash, gully erosion, tunnel erosion, and mass movements) including their controlling factors and mechanisms. Part 2 explores the spatial interactions of these different erosion processes to provide a prerequisite for effective design of comprehensive soil erosion control measures in a watershed. Part 3 evaluates the relative significance of these erosion processes in sediment production, the effectiveness of comprehensive soil and water conservation programs, and the applications of watershed modelling in determining the impact of land-use changes on soil erosion and other ecological processes.

This book was released on 2019-05-16 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.

Available in PDF, EPUB and Kindle. Book excerpt: How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective treatment of persistent agricultural erosion with limited conservation funds requires the identification of critical source areas (CSA) at the subfield scale for watershed scale planning. Publicly available data, physically-based modeling frameworks, and strong conservation district initiatives are now all in place to more directly connect conservation implementation with the underlying physical hydrology. The overall objective of this dissertation was to operationalize physical modeling simulations to identify CSA and inform strategic conservation prioritization. I developed a method for spatially distributing a simplified framework of the Water Erosion Prediction Project (WEPP) model that simulates the physical mechanisms of hillslope hydrology and erosion. A land type characterization of representative WEPP profiles was defined for spatial slope, soil, climate, and management data. Profile simulations mapped to individual flow paths in a regional watershed. This method preserved a higher resolution than the WEPP hillslope approach at 95.6% less computational cost. Simulating multiple conservation practice scenarios identified CSA at the subfield scale as well as conservation practice effectiveness. Erosion decreased by 58% for a change from uniform conventional tillage (CT) to mulch tillage (MT) and by 98% for CT to no-tillage (NT). Treatment of 25% of agricultural area effectively accounted for almost all of this reduction in erosion. Ten-meter conservation buffers were highly effective at reducing sediment delivery to the stream where erosion rates were large.With a voluntary conservation paradigm, identifying CSA is insufficient to promote good conservation. Historically, social and financial drivers of conservation adoption have buffered implementation. A system dynamics model simulated the physical, social, and financial incentive interactions to understand conservation adoption and erosion rates under possible conservation targeting scenarios. Targeting CSA with conservation funding for land retirement with the conservation reserve program and for reduced tillage decreased the total average erosion rate by more than 50%. The most effective use of conservation funds, however, occurs when the diffusion of innovation mechanism is reinforced by broad-scale payments for tillage reduction. By identifying positive feedback, our simulations suggest large potential gains in erosion reduction and conservation fund efficiency are possible. Findings from this work can greatly enhance soil and water conservation planning.
