Book excerpt: Soil erosion is a major environmental issue with a worldwide impact and direct and indirect effects on soil productivity and consequently on human survival. Although a natural process, soil erosion has increased significantly due to human intervention, especially in the last centuries, through diverse activities such as intensive agriculture, overgrazing, urban sprawl, deforestation, and industrial and mining activities. Presently, soil erosion and degradation promoted by human action have reached extreme levels, necessitating urgent measures to promote soil conservation and rehabilitation. This book presents perspectives on soil erosion occurring in different parts of the world as well as some successful initiatives and strategies for soil conservation and rehabilitation.

Download or read book Predicting Rainfall Erosion Losses written by Walter H. Wischmeier and published by . This book was released on 1978 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Land Rights and Expropriation in Ethiopia written by Daniel W. Ambaye and published by Springer. This book was released on 2015-02-13 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis provides a new approach to the Ethiopian Land Law debate. The basic argument made in this thesis is that even if the Ethiopian Constitution provides and guarantees common ownership of land (together with the state) to the people, this right has not been fully realized whether in terms of land accessibility, enjoyability, and payment of fair compensation in the event of expropriation. Expropriation is an inherent power of the state to acquire land for public purpose activities. It is an important development tool in a country such as Ethiopia where expropriation remains the only method to acquire land. Furthermore, the two preconditions of payment of fair compensation and existence of public purpose justifications are not strictly followed in Ethiopia. The state remains the sole beneficiary of the process by capturing the full profit of land value, while paying inadequate compensation to those who cede their land by expropriation. Secondly, the broader public purpose power of the state in expropriating the land for unlimited activities puts the property owners under imminent risk of expropriation.

Download or read book Social and Ecological System Dynamics written by Krystyna Stave and published by Springer. This book was released on 2018-07-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a social—ecological system description and feedback analysis of the Lake Tana Basin, the headwater catchment of the Upper Blue Nile River. This basin is an important local, national, and international resource, and concern about its sustainable development is growing at many levels. Lake Tana Basin outflows of water, sediments, nutrients, and contaminants affect water that flows downstream in the Blue Nile across international boundaries into the Nile River; the lake and surrounding land have recently been proposed as a UNESCO Biosphere Reserve; the basin has been designated as a key national economic growth corridor in the Ethiopian Growth and Transformation Plan. In spite of the Lake Tana Basin’s importance, there is no comprehensive, integrated, system-wide description of its characteristics and dynamics that can serve as a basis for its sustainable development. This book presents both the social and ecological characteristics of the region and an integrated, system-wide perspective of the feedback links that shape social and ecological change in the basin. Finally, it summarizes key research needs for sustainable development.
Download or read book Importance of irrigated agriculture to the Ethiopian economy capturing the direct net benefits of irrigation written by Fitsum Hagos and published by IWMI. This book was released on 2009 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis. Our results show that irrigation yields 219.7% higher income compared to the rainfed system while its current and future contribution to agricultural GDP is estimated to be about 5.7 and 12% although irrigation covers about 5 and 9% of the total cultivated land area, respectively.

This book was released on 2018-05-10 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: We document the state of the extension system in Ethiopia and review the empirical evidence on the links between the key extension services provided, adoption of modern inputs, and agricultural productivity. In particular, we take stock of the provision of agricultural extension services, synthesize the evidence on the performance of the system, and suggest ways that it might contribute to accelerating agricultural growth and poverty reduction in the years ahead.

Download or read book Coffee Atlas of Ethiopia written by Aaron P. Davis and published by Royal Botanic Gardens Kew. This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This richly illustrated volume is the first complete atlas of coffee production in Ethiopia, birth-place of coffee drinking and the main home of wild arabica coffee (Coffea arabica). Around 15 million Ethiopians are coffee farmers, and Ethiopia is Africa's largest coffee producer and one of the most important coffee-growing regions of the world, renowned for its diversity of flavour profiles, including those of the celebrated coffees of Harar, Limu, Sidamo, and Yirgacheffe. The aim of the Coffee Atlas of Ethiopia is to inform the reader about the coffee landscape of Ethiopia. It shows where coffee is grown, where the natural coffee forests are located, and where coffee could be grown. The atlas maps are accompanied by information on coffee farming, environment and climate, and a description of the main coffee areas. Also included in the atlas are key coffee origins, coffee towns and coffee delivery centres, as well as other useful items. The atlas can be used to assess the potential and vulnerability for coffee farming in Ethiopia, as well as provide a logistics resource for the coffee sector and those otherwise working with, or interested in, coffee. It is also an essential reference for resource managers.

Download or read book World Soil Erosion and Conservation written by David Pimentel and published by Cambridge University Press. This book was released on 2009-03-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land degradation from soil erosion has been considered by many to be a problem of significant proportion, affecting some 30-50% of the earth's land surface. At the time of the first publication of this book in 1993, estimates indicated that 10-15 million hectares of land were being lost each year through erosion and salinisation from irrigation and that at such a rate of loss, topsoil reserves on most sloping lands would be depleted within two hundred years. Since humankind's dependency on the land for food is almost total, soil erosion represents a real threat to the security of our food supply. The need for the immediate conservation of the world's soil resources is therefore clear. As part of the response to this need, the International Union for the Conservation of Nature's Commission on Ecology convened a special working group to consider the problem of world soil erosion and to propose practical solutions for soil conservation. This important book presents the outcome of their work.
