Human needs like food and clean water are directly related to good maintenance of healthy and productive soils. A good understanding of human impact on the natural environment is therefore necessary to preserve and manage soil and water resources. This knowledge is particularly important in semi-arid and arid regions, where the increasing demands on limited water supplies require urgent efforts to improve water quality and water use efficiency. It is important to keep in mind that both soil and water are limited resources. Thus, wise use of these natural resources is a fundamental prerequisite for the sustainability of human societies. This book collects 15 original scientific contributions addressing the state of the art of soil and water conservation research. Contributions cover a wide range of topics, including (1) recovery of soil hydraulic properties; (2) erosion risk; (3) novel modeling, monitoring and experimental approaches for soil hydraulic characterization; (4) improvement of crop yields; (5) water availability; and (6) soil salinity. This collection provides more insights into conservation strategies for effective and sustainable soil and water management.
Indigenous soil and water conservation practices are rarely acknowledged in the design of conventional development projects. Instead, the history of soil and water conservation in Africa has been one of imposing external solutions without regard for local practice. There is a remarkably diverse range of locally developed and adapted technologies for the conservation of water and soil, well suited to their particular site and socio-economic conditions. But such measures have been ignored, and sometimes even overturned, by external solutions. Sustaining the Soil documents farmers' practices, exploring the origins and adaptations carried out by farmers over generations, in response to changing circumstances. Through a comparative analysis of conservation measures - from the humid zones of West Africa to the arid lands of the Sudan, from rock terraces in Morocco to the grass strips of Swaziland - the book explores the various factors that influence adoption and adaptation; farmers' perceptions of conservation needs; and the institutional and policy settings most favorable to more effective land husbandry. For the first time on an Africa-wide scale, this book shows that indigenous techniques work, and are being used successfully to conserve and harvest soil and water. These insights combine to suggest new ways forward for governments and agencies attempting to support sustainable land management in Africa, involving a fusion of traditional and modern approaches, which makes the most of both the new and the old.
The book reviews on methods and techniques which have been treated and found useful in semi-arid regions and which might be suitable for use in other condition also. The objective is to make the book relevant for anywhere; where the rainfall is a big problem because of its quantity, distribution or unreliability. It outlines the scale and importance of the problem, difficulties and possibilities for the improvement. It strongly argues and presents evidences that drought is part of the natural order in semi-arid areas and that the recent disasters of degradation and famine in Africa result from misuse and mismanagement of the natural resources which reduced the region's ability to cope with the additional stress of drought.
Combines engineering practices for the solution of erosion and flood control, drainage and irrigational problems. Sufficient hydrologic information--precipitation, infiltration, evaporation, transpiration and runoff--is given as background for design problems discussed later. Makes readers aware that the environment must be considered in the design of soil and water facilities. Features many example problems, with detailed solutions, to facilitate learning.
This bibliography is a list of references to published material on soil erosion and soil and water conservation. Some of these references may not appear to deal directly with erosion or conservation, but they have a pertinent relationship to some phase of the subject.
Streamlined to facilitate student understanding, this second edition, containing the latest techniques and methodologies and some new problems, continues to provide a comprehensive treatment of hydrology of watersheds, soil erosion problems, design and installation of soil conservation practices and structures, hydrologic and sediment yield models, watershed management and water harvesting. It also deals with the special requirements of management of agricultural and forested watersheds. This book is designed for undergraduate students of agricultural engineering for courses in hydrology, and soil and water conservation engineering. It will also be of considerable value to students of agriculture, soil science, forestry, and civil engineering. KEY FEATURES Emphasises fundamentals using numerous illustrations to help students visualise different phenomena Offers lucid presentation of field practices Presents the analysis and design of basic hydraulic structures Devotes an entire chapter to watershed management Provides numerous solved design problems and exercise problems to develop a clear understanding of the theory Gives theoretical questions, and objective type questions with answers to test the students’ understanding.
Have agricultural management efforts begun in the desperation of the Dust Bowl brought us to where we need to be tomorrow? Questions about the environmental footprint of farming make this book required reading. Approximately 62% of the total U.S. land area is used for agriculture, and this land also provides critical ecosystem functions. Authors from each region of the continental United States describe the progress of soil and water conservation to date and visualize how agricultural production practices must change in future years to address the newest challenges.
