Field Measurement of Soil Erosion and Runoff
Soil erosion: the greatest challenge for sustainable soil management
Author: Food and Agriculture Organization of the United Nations
Publisher: Food & Agriculture Org.
ISBN: 9251314268
Category : Technology & Engineering
Languages : en
Pages : 104
Book Description
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.

Soil Erosion in Europe
Author: John Boardman
Publisher: John Wiley & Sons
ISBN: 0470859113
Category : Science
Languages : en
Pages : 878
Book Description
Provides a unique and comprehensive assessment of soil erosion throughout Europe, an important aspect to control and manage if landscapes are to be sustained for the future. Written in two parts, Soil Erosion in Europe primarily focuses on current issues, area specific soil erosion rates, on and off-site impacts, government responses, soil conservation measures, and soil erosion risk maps. The first part overviews the erosion processes and the problems encountered within each European country, whilst the second section takes a cross-cutting theme approach. Based on an EU-funded project that has been running for four years with erosion scientists from 19 countries Reviews contemporary erosion processes and rates on arable and rangeland in Europe Looks at current issues, such as socio-economic drivers, controlling factors specific to the country and changes in land use

Predicting Rainfall Erosion Losses
Author: Walter H. Wischmeier
Publisher:
ISBN:
Category : Agricultural conservation
Languages : en
Pages : 70
Book Description
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.

ISBN: 9780309036498
Category : Technology & Engineering
Languages : en
Pages : 142
Book Description
This new volume is the first independent analysis of an important national data base, the National Resources Inventory. It cites potential uses of the NRI in controlling soil erosion; determining land use; deciding conservation treatment; classifying soils; and protecting groundwater quality. Methods for soil conservation activities, ranging from the ranking of the lands most susceptible to erosion to the measurement and prediction of both wind and water erosion, are recommended throughout the volume.

The meeting was also one of a series organised by the IGBP 1 GCTE Soil Erosion Network, which is a component of GCTE's Land Degradation Task (3.3.2) (Ingram et aI., 1996; Valentin, this volume). One aim of the GCTE Soil Erosion Network is to evaluate the suitability of existing soil erosion models for predicting the possible impacts of global change upon soil erosion. Due to the wide range of erosion models currently, in use or under development, it was decided to evaluate models in the following sequence Favis-Mortlock et al., 1996): • field-scale water erosion models • catchmenr-scale water erosion models • wind erosion models • models with a landscape-scale and larger focus. As part of this strategy, the first stage of the GCTE validation of field-scale erosion models was carried out at the Oxford NATO-ARW. I A list of Acronyms fonns Appendix A.

Land and Water Integration and River Basin Management
Author: Food and Agriculture Organization of the United Nations
Publisher: Food & Agriculture Org.
ISBN: 9789251036556
Category : Business & Economics
Languages : en
Pages : 100
Book Description
Since water sustains life, effective management of water resources demands a holistic approach, linking social and economic development with protection of natural ecosystems. The effective management links land and water resources across the whole of a catchment area or groundwater aquifer. The Workshop addressed the broader issues of water management in the context of land use and the environment and within the framework of river basin management. More specifically, the Workshop dealt with: defining land and water linkages; developing a conceptual framework to predict land, water and plant nutrient interaction; establishing a landscape and river basin approach to integrated management of natural resources; and drafting a programme of action including applied research and modelling, education, extension and manuals and field projects aimed at promoting integrated management of natural resources. This publication contains the report and recommendations of the Workshop and edited versions of eight papers which were presented and discussed in the Workshop.
