This book of 21 chapters is about the ‘how’ of desertification control as opposed to an analysis of the ‘why’ and fills a gap in the desertification-related literature in that it shows what to do in situations ranging from fixing mobile sands to arresting accelerated soil erosion in sloping lands. More than 40 years of work by the Chinese in sandy land reclamation has led to the development of effective techniques. There are numerous illustrations (many in color) to show the successful techniques. This compilation demonstrates that desertification and land degradation can be controlled and reversed with existing techniques in such widely varying environments as the Sahel of Africa to Sri Lanka and the Philippines in SE Asia, from high elevation in Lesotho to low lands on desert margins in Mongolia. Proven approaches include technical interventions, changes in governance and to the legislative framework and policy reform. The contributors are local experts working in-country and bring to the book insights into many little-known aspects of the technical, ecological, social, cultural and economic factors determine success or failure of desertification control efforts. This book will be of great value to professionals from the donor community (World Bank, Asian Development Bank, Islamic Development Bank, UN agencies and NGOs) to graduate student students and land managers tasked with responsibility to arrest and reverse desertification and land degradation. .

This edited volume is devoted to the examination of the implications of the inevitable changes wrought by global change on the welfare and livelihoods of tens of millions of people who live in dryland regions. Global change is more than just climate change and the ramifications of changing trade patterns (geopolitical and economic aspects), the shift to the market economy, demographic factors (population growth, urbanization and re-settlement), receive attention here. Land use change specialists, policy makers and natural resource management agencies will find the book very useful. Chapters focus on examples that are drawn from a number of sources including previously unpublished studies on the impact of climate change, markets and economics on pastoralist and dryland farming households. The key focus is to provide readers with insights into the real world implications of change (including an analysis of the drivers of change) on these vulnerable groups within dryland societies. The role of humans as agents of these changes is canvassed. A regional analysis of the world's drylands is also performed including those in Australia, Argentina, India, North America, China, North Africa, Central Asia and Southern Africa. .

This volume analyzes the global challenges of food security, land use changes, and climate change impacts on food production in order to recommend sustainable development policies, anticipate future food services and demands, and identify the economic benefits and trade-offs of meeting food security demands and achieving climate change mitigation objectives. The key points of analysis that form the conclusions of this book are based on measuring the quantity and quality of land and water resources, and the rate of use of sustainable management of these resources in the context of socio-economic factors, including food security, poverty, and climate change impacts. In six parts, readers will learn about these crucial dimensions of the affects of climate change on food security, and will gain a better understanding of how to assess the trade-offs when combating multiple climate change challenges and how to develop sustainable solutions to these problems. The book presents multidimensional perspectives from expert contributors, offering holistic and strategic approaches to link knowledge on climate change and food security with action in the form of policy recommendations, with a focus on sociological and socio-economic components of climate change impacts. The intended audience of the book includes students and researchers engaged in climate change and food security issues, NGOs, and policy makers.

This book begins with a brief account of the extraordinary sequence of events that led to emergence of grasslands as major vegetation formations that now occupy some of the driest and hottest and the highest and coldest on earth as well as vast steppes and prairies in more temperate climes. It is the story of grasses successfully competing with forests and woodlands, aided and abetted by grazing herbivores and by humans and their use of fire as a tool. It is a story of adaptation to changing climates and the changing biophysical environments. A major focus of the book is the Palaearctic biogeographic realm that extends over some 45 million km² and thus more than 1/3 of the terrestrial ice-free surface on Earth. It comprises extensive grasslands of different types and origin, which can be subdivided into (1) natural grasslands with (1a) steppes (climatogenic in dry climates), (1b) arctic-alpine grasslands (climatogenic in cold climates) and (1c) azonal and extrazonal grasslands (pedogenic and topogenic) as well as (2) secondary grasslands created and sustained by human activities, such as livestock grazing, mowing or burning. Grasslands of the Palaearctic do not only form a major basis for the agriculture of the region and thus its food supply, but are also crucial for other ecosystem services and host a supra proportional part of the realm's plant and animal diversity. To reflect that suitability of grasslands for biodiversity strongly depends on their state, we apply the term High Nature Value grassland to those natural grasslands that are not degraded (in good state) and those secondary grasslands that are not intensified (semi-natural). The situation in a variety of countries where grasslands are evolving under the influence of global climate change is also considered. Case studies are presented on Southern Africa, Eastern Africa, India, China, South America, North America and Australia. The concluding chapter examines a set of themes arising from the chapters that make up the bulk of this book. The following provide a focus: recent history of grassland biomes - brief recap of current thinking and recent trends with special reference to dry grasslands in the Palearctic regions; the current status of grasslands and germplasm resources (biodiversity) - an overview; management systems that ensure sustainability; how to recover degraded grasslands; socio-economic issues and considerations in grassland management; the impacts of environmental problems in grasslands such as future climate change and intensification and the problems/prospects facing pastoralists and other grassland-based livestock producers.
