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
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
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
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.

Book Description
Land is the integrating component of all livelihoods depending on farm, forest, rangeland, or water (rivers, lakes, coastal marine) habitats. Due to varying political, social, and economic factors, the heavy use of natural resources to supply a rapidly growing global population and economy has resulted in the unintended mismanagement and degradation of land and ecosystems. 'Sustainable Land Management' provides strategic focus to the implementation of sustainable land management (SLM) components of the World Bank's development strategies. SLM is a knowledge-based procedure that integrates land, water, biodiversity, and environmental management to meet rising food and fiber demands while sustaining livelihoods and the environment. This book, aimed at policy makers, project managers, and development organization, articulates priorities for investment in SLM and natural resource management and identifies the policy, institutional, and incentive reform options that will accelerate the adoption of SLM productivity improvements and pro-poor growth.

Book Description
This book focuses on the global effects of land degradation, but emphasizes other important levels of land degradation: at the field level, it may result in reduced productivity; at the national level, it may cause flooding, and sedimentation; and, at the global level, it can contribute to climate changes, damaging bio-diversity, and international waters. The effects on climate changes are explored, and the report questions the extent to which land degradation on agricultural land, affects climate change. Does it increase emissions of greenhouse gases? Does it affect land's capacity to serve as a carbon sink? Can appropriate management enhance both land's productivity, and its capacity to store carbon? The carbon cycle in soils is analyzed, indicating land degradation is likely to reduce the ability of soils to serve as carbon sink, and release stored carbon into the atmosphere, and, bio-diversity effects are likely to be adverse. Global benefits of land degradation control, include afforestation, to allow increased carbon sequestration, and provide adequate bio-diversity habitats; and, community-based wildlife management, can provide alternatives to some marginal areas. Although integrating global dimensions into land degradation control projects, may reverse the field level, or national problems it is causing, difficulties and constraints will likely contribute to the failure of these projects.
