Drylands, which cover over half the world's area, have witnessed rapid development, exploitation and change with the discovery of mineral reserves, urbanization and population growth. Environmental management is critical to the conservation and sustainable use of resources. This comprehensive text offers a systematic study of the physical nature of drylands and the history of human response to and uses of these harsh landscapes. Detailed case studies, including urban as well as pastoral drylands from California to Soviet Central Asia, the Middle East, the Sahara and Australia, contrast different management approaches and problems.

This second edition provides an account of modern environmental issues and the physical and socio-economic framework in which they are set. It explains the principles and applications of the different parts of the Earth's system: the lithosphere, atmosphere, hydrosphere and biosphere, and explains the interrelationships within and between these systems. It explores the present environmental crisis, examines how the planet Earth fits in the wider universe and explores human-environment interactions. (Midwest).

We have always had land in which the agricultural productivity is limited because there is not enough moisture. Systems of farming and burning often degrade dryland further until it is desert. Today, however, the problem is becoming much more serious. Over 20 per cent of the world's population lives in dryland areas, and unless action is taken drylands will increase dramatically. This book focuses on the people who live and .farm in the drylands, their use of land resources and the economic returns from their decisions. In a clear and thorough economic appraisal, the authors show how it is still possible to arrest the problem. Originally published in 1989

Drylands have been cradles to some of the world’s greatest civilizations, and contemporary dryland communities feature rich and unique cultures. Dryland ecosystems support a surprising amount of biodiversity. Desertification, however, is a significant land degradation problem in the arid, semi-arid and dry sub-humid regions of the world. Deterioration of soil and plant cover has adversely affected 70% of the world’s drylands as a result of extended droughts as well as mismanagement of range and cultivated lands. The situation is likely to worsen with high population growth rates and accompanying land-use conflicts. The contributions to The Future of Drylands – an international scientific conference held under the leadership of UNESCO – address these issues and offer practical solutions for combating desertification along with conserving and sustainably managing dryland ecosystems. Major themes include the conservation of dryland biological and cultural diversity and the human dryland interface. This volume documents how our improved understanding of drylands provides insight into the health and future prospects of these precious ecosystems that should help ensure that dryland communities enjoy a sustainable future.

The arid frontier has been a challenge for humanity from time immemorial. Drylands cover more than one-third of the global land surface, distributed over Africa, Asia, Australia, America and Southern Europe. Disasters may develop as a result of complex interactions between drought, desertification and society. Therefore, proactive planning and interactive management, including disaster-coping strategies, are essential in dealing with arid-frontier development. This book presents a conceptual framework with case studies in dryland development and management. The option of a rational and ethical discourse for development that is beneficial for both the environment and society is emphasized, avoiding extreme environmentalism and human destructionism, combating both desertification and human livelihood insecurity. Such development has to be based on appropriate ethics, legislation, policy, proactive planning and interactive management. Excellent scholars address these issues, focusing on the principal interactions between people and dryland environments in terms of drought, food, land, water, renewable energy and housing. Audience: This volume will be of great value to all those interested in Dryland Development and Management: professionals and policy-makers in governmental, international and non-governmental organizations (NGOs), as well as researchers, lecturers and students in Geography, Environmental Management, Regional Studies, Development Anthropology, Hazard and Disaster Management, Agriculture and Pastoralism, Land and Water Use, African Studies, and Renewable Energy Resources.
