Book Description
Seminar paper from the year 2021 in the subject Agrarian Studies, grade: A, , course: Soil and water conservation, language: English, abstract: The review focuses on the importance of soil and water conservation practices on soil properties in Ethiopia. The study conducted in various parts of the country showed that the implemented soil bund reduced annual runoff and soil loss at different rates. Soil and water conservation have improved the soil physicochemical properties on conserved cropland (BD, SMC, infiltration rate, clay content, pH, CEC, av. K, av. P, SOC and TN) than in the adjacent cropland without soil and water conservation measures. Soil and water conservation, reduce the removal of fertile topsoil and improves soil moisture, which favors crop growth as a result grain yield of the crops were increased at various rates based on agro ecology, crop type and local management practices. In general, the effect of constructed soil and water conservation had clearly showed positive impact on soil physicochemical properties and crop yields. Therefore, to reduce soil erosion sustainably, different soil and water conservation options should be introduced and used considering agro ecology, socio-economic profile and climatic condition of the intervention area. Soil erosion is one of the several major deteriorative processes which results in soil degradation and declining agricultural productivity in Ethiopia due to dense population, high livestock density and intensive crop production in the area. Soil and water conservation practice is one the mechanism used to reduce soil and associated nutrient loss; thus, reduce the risk of production. Efforts were started through soil and water conservation strategy at a large scale on farmland since the mid-1970 and 1980’s. However, soil erosion still persists and become major threats of the Ethiopian region.

Book Description
The Ethiopian economy is predominantly agrarian, where almost half of the GDP is contributed by agricultural sector. However, the performance of the sector is very weak and suffers from various setbacks. Technological backwardness, environmental degradation, population increase and related pressure. The Amhara Regional State is one which highly affected by land degradation through soil erosion. To reverse the severity of the problem, soil and water conservation practices were introduced in different parts of the region including the study area. However, the attempt has been limited. Various factors, such as, households, socio-economic, physical and institutional factors, are attributed for the limited soil and water conservation practices of the past decades. The result of binary logit also showed that, total farm size, household labor availability, training on soil and water conservation practices and farm slopes were the major factors that affect the adoption of improved soil and water conservation practices positively, while farm distance of the households from the residence is negatively significant with plots far to the residences.

Book Description
For as far into the future as we can see, governments will probably topple, power will continue to exchange hands, the climate will undergo continuous change, and the global economy will ebb and flow like the oceans. But for the world's many diverse countries-whether they be highly industrialized or third world-one thing will always remain constant: the need to solve the planet's pressing soil and water conservation problems, as well as implement effective policies. But why do some policy initiatives succeed while others fail? Soil and Water Conservation Policies and Programs: Successes and Failures addresses this very question. Based on an international conference held in Prague, this book debates the strengths and weaknesses of soil and water conservation initiatives implemented in North America, Europe, and Australia. Soil and water conservation policies in the United States, Canada, Germany, Austria, Yugoslavia, and other countries are examined through the eyes of technical and soil scientists. And the book also addresses specialized topics, such as agricultural pollution abatement in Poland, and private farmers and contemporary conservation subsidy programs in the Czech Republic. With its thorough treatment of the subject matter, Soil and Water Conservation Policies and Programs: Successes and Failures contributes to resolving one of the world's most pressing conservation issues.

Book Description
Soil erosion has become a problem of crisis proportions in developing countries around the globe, and better approaches to land management are desperately needed. This book provides analytical frameworks to guide the creation and appraisal of soil erosion control programs. The authors discuss a broad range of important issues involved in designing and implementing more effective soil conservation programs. The book begins with a discussion of the physical and economic dimensions of soil erosion and an estimation of the extent of the problem. It then explains how to improve the evaluation of soil conservation programs by integrating scientific knowledge with economic methods and procedures. A series of practical illustrations graphically demonstrates the application of the concepts derived from the theory. The most important organizational, institutional, technical, and macroeconomic aspects of soil and land management appraisal are outlined, and the major elements of project or program design are also pinpointed and illustrated. Finally, the book suggests areas most in need of future research.

Book Description
First published in 1985. This book examines wide variety of ways in which environmental deterioration, in particular soil erosion, can be viewed and the implicit political judgements that often inform them. Using the context of developing countries, where the effects tend to be more acute due to underdevelopment and climatic factors, this work aims to examine this source of uncertainty and make explicit the underlying assumptions in the debate about soil erosion. It also rejects the notion that soil erosion is a politically neutral issue and argues that conservation requires fundamental social change. This title will be of interest to students of environmental and developmental studies.

Book Description
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.

Book Description
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.
