Economics of Land Degradation and Improvement – A Global Assessment for Sustainable Development


Book Description

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.










Water Resources Management in Ethiopia


Book Description

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.










Forest coversion - soil degradation - farmers´ perception nexus: Implications for sustainable land use in the southwest of Ethiopia


Book Description

Forest conversion - soil degradation - farmers’ perception nexus: Implications for sustainable land use in the southwest of Ethiopia. Resettlements in the forest regions instigate considerable impacts on the natural resource base. This study presents a comparative assessment of the biophysical processes of resource degradation and the farmers’ awareness in a cereal-based farming system of the settlers and an indigenous coffee-based farming system. The study analyzes the extent of forest conversion and soil degradation in the two farming systems. Furthermore, the farmers’ response and coping mechanisms are assessed. The need for providing land management technologies to farmers to use their resources sustainably is emphasized and a review of the resettlement policy is underlined.




Caring for the Land

Sustainable land management, gender, and agricultural productivity: Evidence from Ethiopia's fragile watershed observatory


Book Description

Land degradation is a pressing global challenge, with three billion people residing in degraded landscapes. The global cost of land degradation is estimated to be about $300 billion per year, with Africa south of the Sahara accounting for 26 percent of the total global costs due to land-use and land-cover changes. In Ethiopia, it is estimated that more than 85 percent of land is moderately to severely degraded due to changes in land use and cover, costing the country an estimated US$4.3 billion annually. In order to halt further degradation and support essential restoration through sustainable land management (SLM) and related investments, the Water and Land Resource Center (WLRC) and its consortium of development partners established six learning watersheds in Central and North-Western Ethiopia with the ultimate goal of improving water security and crop and livestock productivity.
