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.

Book Description
The costs of doing nothing about land degradation are several times higher than the costs of taking action to reverse it. Despite the crucial role land plays in human welfare and development, investments in sustainable land management are low, especially in developing countries. These findings come from the book, Economics of Land Degradation and Improvement¿A Global Assessment for Sustainable Development, which examines the costs of land degradation and what needs to be done to reverse it. The book reveals the cost of land degradation in case studies for 12 countries, analyzes the drivers, and identifies strategies for sustainable land management. It focuses on two kinds of land degradation: long-term loss of value of land ecosystem services due to land use and cover change (LUCC) and the use of land-degrading management practices on cropland and grazing lands that do not undergo LUCC. Six major biomes that accounted for about 86 percent of global land area in 2001 are covered, including forest, shrub lands, grasslands, cropland, barren land, and woodlands. Thirty-three percent of grasslands, 25 percent of croplands, and 23 percent of forests experienced degradation over the last three decades.

Book Description
This book takes a new approach on understanding causes of extreme poverty and promising actions to address it. Its focus is on marginality being a root cause of poverty and deprivation. “Marginality” is the position of people on the edge, preventing their access to resources, freedom of choices, and the development of capabilities. The book is research based with original empirical analyses at local, national, and local scales; book contributors are leaders in their fields and have backgrounds in different disciplines. An important message of the book is that economic and ecological approaches and institutional innovations need to be integrated to overcome marginality. The book will be a valuable source for development scholars and students, actors that design public policies, and for social innovators in the private sector and non-governmental organizations.

Book Description
Why does land management so often fail to prevent soil erosion, deforestation, salination and flooding? How serious are these problems, and for whom? This book, first published in 1987, sets out to answer these questions, which are still some of the most crucial issues in development today, using an approach called ‘regional political ecology’. This approach acknowledges that the reason why land management can fail are extremely varied, and must include a thorough understanding of the changing natural resource base itself, the human response to this, and broader changes in society, of which land managers are a part. Land Degradation and Society is essential reading for all students of geography, agriculture, social sciences, development studies and related subjects.

Book Description
Most African countries strive for both poverty reduction and sustainable land management, yet information on the exact relationship between these goals is limited. This report seeks to fill the gap by demonstrating a strong linkage between poverty and land management. Using Uganda as a case study, the authors show that certain policies, such as investments in soil and water conservation and agroforestry, may simultaneously increase productivity and reduce poverty and land degradation. Other strategies, including development of rural roads, non-farm activities, and rural finance, may reduce poverty without significantly affecting productivity or land management. Some policies, however, will likely involve trade-offs among different goals and will need to have their negative impacts minimized. Those in government, NGOs, the private sector, or academia who are concerned about sustainably reducing poverty in Sub-Saharan Africa will benefit from this analysis of how to pursue these key development goals.

Book Description
Dryland degradation and desertification now affect almost a billion people around the world. Tragically, the biological resources and productivity of millions of acres of land are lost to desertification each year because people remain unaware of strategies and techniques that could improve yields, reduce risk, and begin healing the world's deserts. A Guide for Desert and Dryland Restoration is the first book to offer practical, field-tested solutions to this critical problem. Author David Bainbridge has spent more than 25 years actively involved in restoring lands across the American Southwest. A Guide for Desert and Dryland Restoration presents the results of his years of fieldwork, as well as research and experience from scientists and practitioners around the globe. The book discusses the ecology of desert plants, explores the causes of desertification and land abuse, and outlines the processes and procedures needed to evaluate, plan, implement, and monitor desert restoration projects. It sets forth economical and practical field-tested solutions for understanding site characteristics, selecting and growing plants, and ensuring that they survive with a minimal amount of water and care. Each chapter represents a guide to a critical topic for environmental restoration; extensive photographs, diagrams and drawings give detailed information for immediate application, and additional resources are included in appendixes. A Guide for Desert and Dryland Restoration is the first comprehensive book focused on restoring arid regions, and clearly demonstrates that arid lands can be successfully rehabilitated. In addition to restorationists, the book will be an invaluable resource for anyone working in arid lands, including farmers, ranchers, gardeners, landscapers, outdoor recreation professionals, and activists.

Book Description
This book compiles a set of 26 papers that present the direct, practical experiences and results of a large number of local practitioners and experts that supported the Transboundary agro-ecosystem management project of the Kagera river basin (Kagera TAMP) during the period 2010-2015. The book has been compiled by the Land and Water Division of the Food and Agriculture Organization of the United Nations (FAO) to reflect the wide range of experiences, approaches and tools that were used for promoting participatory diagnostics, adaptive management and adoption of sustainable land and agro-ecosystem management (SLaM) practices from farm to watershed / landscape scale. The project was supported by the Global Environment Facility (GEF), the Governments of the four countries that share the transboundary basin - Burundi, Rwanda, the United Republic of Tanzania and Uganda and project partners. It is hoped that the lessons learned are considered and taken up by the Governments and the TerrAfrica partnership for scaling up and mainstreaming SLaM as part of the wider set of lessons learned from the 36 projects in 26 countries under the Terrafrica Strategic Investment programme, including Kagera TAMP.

Book Description
This book provides an authoritative review of the resources of soils, water, climate, forests and pastures on which agriculture depends. It assesses the interactions between land resources and wider aspects of development, including population and poverty. Unless action is taken, the developing world will face recurrent problems of food security and conflict. The book gives some forcefully-expressed criticisms of current methods of assessing land degradation and placing an economic value on land. It should be read by all involved in rural development, including scientists, economists, geographers, sociologists, planners, and students of development studies. It provides a summary and perspective of the field of land resources, and suggests improvements needed to conserve resources for future generations. The hardback edition of the book received excellent reviews.

Book Description
Land degradation is increasingly considered as a global problem. The extent of degraded and degrading areas adversely impacts on large numbers of people and leads to significant social and economic costs, thus raising the questions: In which way is it worth taking action against land degradation? Where and when should action take place, and what are costs related to certain actions? For policy makers it is important to know the social and economic costs linked to the current and future status of land degradation. A conceptual framework that allows comparing the costs of action against land degradation versus the costs of inaction is provided in this book. The applicability of the framework is illustrated with case studies and prepares the ground for a global assessment on the costs of land degradation.
