This book was released on 2015-11-11 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume deals with land degradation, which is occurring in almost all terrestrial biomes and agro-ecologies, in both low and high income countries and is stretching to about 30% of the total global land area. About three billion people reside in these degraded lands. However, the impact of land degradation is especially severe on livelihoods of the poor who heavily depend on natural resources. The annual global cost of land degradation due to land use and cover change (LUCC) and lower cropland and rangeland productivity is estimated to be about 300 billion USD. Sub-Saharan Africa (SSA) accounts for the largest share (22%) of the total global cost of land degradation. Only about 38% of the cost of land degradation due to LUCC - which accounts for 78% of the US$300 billion loss – is borne by land users and the remaining share (62%) is borne by consumers of ecosystem services off the farm. The results in this volume indicate that reversing land degradation trends makes both economic sense, and has multiple social and environmental benefits. On average, one US dollar investment into restoration of degraded land returns five US dollars. The findings of the country case studies call for increased investments into the rehabilitation and restoration of degraded lands, including through such institutional and policy measures as strengthening community participation for sustainable land management, enhancing government effectiveness and rule of law, improving access to markets and rural services, and securing land tenure. The assessment in this volume has been conducted at a time when there is an elevated interest in private land investments and when global efforts to achieve sustainable development objectives have intensified. In this regard, the results of this volume can contribute significantly to the ongoing policy debate and efforts to design strategies for achieving sustainable development goals and related efforts to address land degradation and halt biodiversity loss.
Download or read book The Political Economy of Soil Erosion in Developing Countries written by Piers Blaikie and published by Routledge. This book was released on 2016-05-20 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil erosion has been recognized as one of the biggest problems of agriculture worldwide and even more so in developing countries. This dissertation models the dynamic effects of soil erosion both at the farm level and its off-site cumulative effects on inland wetlands by using optimal control theory. Based on a productivity approach, two empirical procedures are derived from the theoretical model. One procedure relies on a limited data set to estimate the shadow price of soil erosion. The other procedure estimates the off-site impacts of soil erosion on wetland services, specifically flood control, that have been gradually reduced due to sedimentation between 1975 and 2001. These estimates of on-site and off-site impacts of soil erosion are then used to assess the cost of agricultural modernization due to environmental degradation and to establish a baseline for policy analysis. The empirical studies are done in a watershed of about 1.4 million hectares located in the south of CÃ3rdoba, Argentina, where agricultural modernization driven, mainly by market forces, has been gradually moving away from low input to intensive agriculture. This transformation is causing an increase in production but it is also reducing the long-term productivity of agriculture had and degrading wetlands. The results show that agricultural modernization has gradually increased the cost of soil erosion. Between 1986 and 1999, the total cost imposed by agricultural modernization was between $182 and $316 million in real 2000 dollars. Assuming that the historical trend holds, the baseline measured by the net present value loss (at a 6% of discount rate) for the next 30 years will be about $121 million, which includes $81 million lost due to future wetland degradation and $40 million lost due to increasing the soil erosion rate on-site. The results also suggest that loss of wetland services by degradation can be as important as the loss of the wetlands themselves. However, the former is often ignored in the political agenda. Finally, the study concludes that along with agricultural modernization, a policy to control soil erosion and prevent inland wetland degradation should be established.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This is the second of two volumes that together provide a global overview of the impact of agriculture on soil degradation, tracing the most critical drivers like the use and abuse of agrochemicals, mechanization, overgrazing, irrigation, slash and burn agriculture, and the use of plastics. Soil degradation caused by agriculture practices is a complex issue which depends on the interaction of social, economic, political, and environmental aspects. In this book, expert contributors elucidate the extension of the effects of agriculture on soil degradation in Europe, a continent with different cultures and political backgrounds that affect agricultural practices. Readers will also find in this book authoritative solutions to minimize the effects of agriculture intensification and land-use in this continent. Divided into 12 chapters, the book offers a European perspective on soil quality and sustainable management, including case studies about the impact of chemical agents like fertilizers, herbicides, pesticides, and soil acidification and microplastics pollution in agriculture practices from countries such as Croatia, Czech Republic, Estonia, Latvia and Lithuania, Germany, Portugal and Greece, Hungary, Iceland, Italy, Slovenia, Spain, Sweden, and Ukraine. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.

This book was released on 2020-11-27 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2020 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, language: English, abstract: Physical soil and water conservation technologies including soil and stone bunds, cut-off drains and ditches/waterways were implemented in different place of Ethiopia particularly in the north and North West parts to minimize soil degradation. Regarding to this many research findings investigated the rate of soil erosion, the type of technologies adopted to reduce soil erosion and their effects on agricultural production. However their ecological and socio- economic impacts (particularly ecological impacts) were not highly investigated. Therefore this study was conducted at Gondar Zuria Woreda Northwest Ethiopia to investigate ecological and socio-economic impacts of physical SWC technologies. For this purpose both quantitative and qualitative designs were employed. A multistage sampling approach was used to identify the research subjects. Quantitative and qualitative data were collected via structured questionnaire, semi-structured key informant interview, FGDs and through field observations. The findings were analyzed with the help of descriptive and inferential statically tools. Land sat satellite image with Arc-GIS was employed to analyze the bio-physical dynamics of the study areas. Ten major factors those estimated as obstacles to implement physical soil and water conservation technologies in the study areas such as size of land; money; households labor; farmers knowledge (training); land tenure, farmers perception, sex, time and culture constraints were determined using logit regression model. Owing to this, the finding indicated that farm households who implemented each of (all) the newly installed physical SWC technologies were significantly greater than who did not implemented each of (all) technologies.

Download or read book Productivity Effects of Cropland Erosion in the United States written by Pierre R. Crosson and published by Routledge. This book was released on 2016-03-17 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1970’s, agriculture in the United States seemed to be booming. With an extra demand for crops, extra acres were taken on to increase production which was predicted to increase further with an ever-growing population. However, concerns were beginning to be raised over the adequacy of land for crops as potential croplands began to be converted into urban areas as well as the effects of soil erosion decreasing the quality of these croplands. Originally published in 1983, this study investigates the threats to crop productivity in the U.S. with a focus on human-made problems. This title will be of interest to students of environmental studies.
