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.

The research presented in this book demonstrates how an integrated ‘systems’ approach to farming in the watershed context increases the effectiveness of a production system and improves people’s livelihoods. It takes an integrated approach, using one watershed in Ethiopia as a ‘laboratory’ or model case study to focus on the interaction and interdependence between land, water, crops, soil, water harvesting, supplemental irrigation, forestry, socio-economic aspects, livestock and farm tools. A range of linked studies was conducted with active participation of the farming community and other relevant stakeholders, such as the local offices of agriculture and extension services. The starting point for the work was the premise that previous efforts to solve farming system constraints using a piecemeal approach or discipline-specific focus have not been successful. Thus, addressing agricultural and environmental constraints through a holistic approach enables the generation of comprehensive technologies to sustainably improve the natural resource base and livelihoods of communities. The authors discuss trade-offs and resource allocation, demonstrating how the environment can be protected while also improving productivity. A unique feature is the methodology developed for the selection of suitable fields and farmers to implement new approaches or improved technologies, to achieve production increases while reducing degradation of sensitive agro-ecosystems. It is also shown how the watershed scale is a valuable basis for assessing the protection of fragile lands.

Sub-Saharan Africa, the poorest region worldwide, has only recently begun to fully address the issues of meeting the water needs of its rapidly growing population, to reduce the deepening poverty besetting the region and to accelerate economic growth. The Nile Basin, characterized by sharp spatial and temporal variations in water resources and including countries with different economies, social and political structures and capacities, illustrates the challenges of developing and managing the waters of the Nile River and its tributaries, lakes and wetlands equitably among its 10 riparian countries. Ethiopia, the major source of the Nile but one of the poorest countries in the Nile Basin, has recently begun to implement plans to harness more Nile water through hydroelectric and irrigation development both for national use and for transboundary development as part of the Nile Basin Initiative. The Ethiopian government and communities, by using different management approaches and resources, are trying to boost water, energy and food production, strengthen conservation efforts and mitigate potential repercussions of water resources development. These initiatives and programs have not been comprehensively examined. In this study, the editors address these and other issues surrounding water resources management in all economic and water sectors in Ethiopia within the setting of the Nile Basin, the first comprehensive treatment of this subject. The wide scope of this book is consistent with the tenets of integrated water resources management, which demand that all water uses be managed in an integrated fashion for optimum and sustainable benefits to all water users, both humans and ecosystems. This book reveals the impacts of various resource management approaches and practices in Ethiopia and the Nile Basin. Specifically, it examines how deforestation and prevailing land use practices have exacerbated soil aridity and flood events, why irrigated agriculture and hydropower development have caused floodplain degradation, livelihood hardships and water-related diseases, where industrial and agricultural development is increasingly polluting water resources, how household water supplies can be obtained through rainwater harvesting and the dependence on hydropower reduced through alternative energy sources and how misguided government policies have impeded efforts to deal with these and other challenges. Results reveal dynamic interrelationships between these processes and identify the human and environmental driving forces, which must be understood in effective integrated water resources management. Another unique contribution of this book is the examination of the role of government and communities in managing water resources in Ethiopia. Results show that the top-down approach used by the socialist Derg government in soil and water conservation and social programs exacerbated water problems and reduced community participation. Moreover, the failure of its economic program reduced agricultural production, increasing dependency on relief food and further impeding community initiatives in soil and water conservation activities. Many elements of central planning persist in spite of the decentralization drive by the current government, but there is evidence that integration of the top-down and bottom-up approaches to water resources management is necessary (and feasible) to strengthen and up-scale programs to the national level. The book identifies a number of customary water and soil management practices and institutions that may strengthen especially community-based rainwater harvesting, small-scale irrigation, reforestation, soil and water conservation and flood control efforts. This is an important book for researchers and students of resources management, rural development, hydrology and African studies.

This book provides a succinct but comprehensive presentation of key geomorphological locations and topics including information about geomorphological heritage and maps to visit the most important sites. Apart from often being remarkably scenic, landscapes reveal stories that often can be traced back in time tens of million years and include unique events. This is particularly true for Ethiopia where spectacular examples of different landforms are present. Its geomorphology varies from highlands, marked by high volcanoes and incised by deep river gorges, to the rift valley lakes endorheic systems and the below sea level lowlands with characteristic landscapes which are unique in the world. Landscapes and Landforms of Ethiopia highlights all these topics including essential information about geology and tectonic framework, past and present climate, hydrology, geographical regions and long-term geomorphological history. It is a highly informative book, providing insight for readers with an interest in geography and geomorphology.

Ethiopia is facing environmental and poverty challenges, and urgently needs effective management of its environmental resources. Much of the Ethiopian landscape has been significantly altered and reshaped by centuries of human activities, and three-quarters of the rural population is living on degraded land. Over the past two decades the country has seen rapid economic and population growth and unparalleled land use change. This book explores the challenges of sustaining the resource base while fuelling the economy and providing for a growing population that is greatly dependent on natural resources for income and livelihoods. Adopting a political ecology perspective, this book comprehensively examines human impacts on the environment in Ethiopia, defining the environment both in terms of the quantity and quality of renewable and non-renewable natural resources. With high levels of economic production and consumption also come unintended side effects: waste discharges, emissions of pollutants, and industrial effluents. These pollutants can degrade the quality of water, air, land, and forests as well as harm the health of people, animals, and other living organisms if untreated or disposed of improperly. This book demonstrates how the relationship between society and environment is inherently and delicately interwoven, providing an account of Ethiopia’s current environment and natural resource base and future considerations for environmentally sustainable development.

Soils represent the result of a complex set of interacting processes and are an integral component of the environment. Yet soils remain the most undervalued and misused of the Earth's resources. This work examines the fundamental importance of soils. Combining practical analysis and interpretation with a theoretical approach, the authors discuss the properties of soils, debate the environmental factors that influence their development, and address their resulting spatial characteristics on a global scale. Examining the impact of environmental controls on soil formation this book also analyzes the role of soils as components of natural environmental systems, and soil-human interactions. A glossary of terms aids the less scientific reader. Adopting macro and micro-scale, pure and applied, spatial and temporal, and natural and human related approaches, this book offers an understanding of soils within an environmental context. As environmental problems, such as pollution, acidification, erosion and climatic change become matters of greater concern, this work offers an understanding for readers across a spectrum of environmentally-related subjects.
