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.

Land Degradation explores the substantial decrease in an area's biological productivity or usefulness to humans due to human activities. The second edition of Johnson and Lewis's well-received text thoroughly examines this growing area of study using a global perspective, as well as up-to-date information. The various case studies cover the history of land degradation, look at local and regional effects of human interactions with the environment, and compare creative destruction with destructive creation.

Soils and Landscape Restoration provides a multidisciplinary synthesis on the sustainable management and restoration of soils in various landscapes. The book presents applicable knowledge of above- and below-ground interactions and biome specific realizations along with in-depth investigations of particular soil degradation pathways. It focuses on severely degraded soils (e.g., eroded, salinized, mined) as well as the restoration of wetlands, grasslands and forests. The book addresses the need to bring together current perspectives on land degradation and restoration in soil science and restoration ecology to better incorporate soil-based information when restoration plans are formulated. - Incudes a chapter on climate change and novel ecosystems, thus collating the perspective of soil scientists and ecologists on this consequential and controversial topic - Connects science to international policy and practice - Includes summaries at the end of each chapter to elucidate principles and key points

This edited book covers all aspects of forest deforestation and degradation in detail and their link to land degradation. Poor natural resource management is often a contributory factor in the depletion of resources particularly like degradation of land which hinders the goals to achieve land degradation neutrality (LDN). Sustainable Development Goal (SDG) target 15.3 states: “By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought, and floods, and strive to achieve a land degradation-neutral world.” To achieve the set goals a comprehensive multidirectional approach is required involving policymakers, field functionaries, researchers, and above all educators. The book compiles the field experiences and wisdom of some of the best researchers and authors working in the field of land degradations for quite a long time. The objective of the book is to disseminate the status of land degradation, the importance of achieving land degradation and share success stories of reclaiming Land degradation, and suggests means and ways of achieving land degradation neutrality. This book act as a repository of knowledge on Land degradation neutrality for students, researchers and practitioners, and policy planners.

Major advances in the use of geographic information systems have been made in both anthropology and archaeology. Yet there are few published discussions of these new applications and their use in solving complex problems. This book explores these techniques, showing how they have been successfully deployed to pursue research previously considered too difficult--or impossible--to undertake. Among the projects described here are studies of land degradation in the Peruvian Amazon, settlement patterns in the Pacific northwest, ethnic distribution within the Los Angeles garment industry, and prehistoric sociopolitical development among the Anasazi. Following an introduction that discusses the theory of geographic information systems in relation to anthropological inquiry, the book is divided into sections demonstrating actual applications in cultural anthropology, archaeology, paleoanthropology, and physical anthropology. The work will be of much interest within all these communities.

Space-critical infrastructures represent an interdependent system of systems consisting of workforce, environment, facilities, and multidirectional interactions. These are essential for the maintenance of vital societal functions such as health, safety, security, mobility, and the economic and social well-being of people, and their destruction or disruption would have a significant impact on society as a whole. In all, 79 nations and government consortia currently operate satellites, with 11 countries operating 22 launch sites. Despite creating new challenges, this multi-actor environment offers opportunities for international cooperation, but making the most of these opportunities requires a holistic approach to space-critical infrastructure, away from strictly defined space technologies and towards understanding the resilience of complex systems and how they are intertwined in reality. This book presents papers from the NATO Advanced Research Workshop (ARW), entitled Critical Space Infrastructure: From Vulnerabilities and Threats to Resilience, held in Norfolk, Virginia, USA from 21-22 May 2019. The ARW brought together representatives from academia, industry, and international organizations in an effort to deepen scientific and technological understanding of space-critical infrastructures and explore the implications for national and international space security and resilience. It examined space as a critical infrastructure from a multidisciplinary perspective in accordance with NATO’s Strategic Concept. The 29 chapters in the book are divided into six sections covering space infrastructure: governance; cybersecurity; risk, resiliency and complexity; emerging technologies such as block chain, artificial intelligence and quantum computing; application domains; and national approaches and applications.

’’Desertification’’ means land degradation in arid, semiarid, and dry sub-humid areas resulting from various factors, including climatic variations and human activities. Combat Desertification advocates for the importance of inclusive cooperation to restore and rehabilitate degraded land and contribute towards achieving the overall Sustainable Development Goals. Land has been an overlooked component in sustainable development for years. Now, we view land as a vital link to provide solutions to cope with many other development challenges such as climate change, secure water and energy resources, promoting inclusive growth, and so on. It is widely accepted that satellite remote sensing and Geo-informatics system offers considerable advantages for land degradation and desertification assessments. With a comprehensive spatial coverage it is intrinsically synoptic, and provides objective, repetitive data which contribute to resource assessments and monitoring concepts of the process of desertification. However, if these observations can be coupled with GIS-based ecological modeling concepts, they may develop their full capacity to be used for modifying and adapting mitigation strategies.
