Changing desert areas for land use implies a lot of ecological problems. These and related ones are dealt with in this book covering various interdisciplinary and international aspects. Large areas in arid and semi-arid regions are already polluted in various ways. One of the biggest problems is the anthropogenic salinization by inadequate means of agriculture and irrigation. Additionally, most arid areas in the world are dramatically overgrazed. Methods and practices of a sustainable land use in deserts are urgently needed in many arid regions. This book gives a broad survey on some of the affected regions of the world as well as some case studies from elsewhere (Aral Sea, Negev desert, Namib desert etc.). Thus, basic and applied sciences are brought together. Water management in deserts, grazing systems or reclamation of desertified areas are among the topics of this book, as well as social and economic aspects

This book presents the outcome of the Towards Sustainable Land Use in Asia (SLUAS) project, which was the pilot undertaking for development in a series of projects on land use. Monsoon Asia, with its huge and still increasing population and rapid socioeconomic changes, is regarded as a major hot spot of global change in general and of land use change in particular. The major issues include urbanization, rural development, land-related problems such as food problems, and disasters in the context of global change and sustainability. Future Earth, the new international research framework established by International Council for Science (ICSU), the International Social Science Council (ISSC), and other international academic or funding organizations for a sustainable world, has chosen the Global Land Project (GLP) as one of the first such international projects it has endorsed that originated from International Geosphere/Biosphere Programme (IGBP) and/or International Human Dimensions Programme (IHDP). This endorsement is a clear indication of the importance of the issues related to land use and its changes. Land use change is an essential driving force of environmental change, a result of socioeconomic and environmental changes, and is a major environmental change itself. Because of this complex and multifaceted nature and the difficulties in obtaining relevant data with historical depth, this phenomenon has not been studied fully in the context of global change or sustainability. It is hoped that this book is of use to those who are concerned about the present and future land use in the world.

"Because of the major opportunities and risks associated with it, and the complexity of the subject, bioenergy policy has in a short time become a challenging political task for regulators and planners - a task that can only be accomplished through worldwide cooperation and the creation of an international framework. WBGU's (German Advisory Council on Global Change) central message is that the sustainable potential of bioenergy, which can be tapped all over the world, should be utilized - provided that threats to sustainability are avoided. In particular, the use of bioenergy must not endanger food security or the goals of nature conservation and climate change mitigation."--Publisher's description
