Book Description
An argument that the perception of arid lands as wastelands is politically motivated and that these landscapes are variable, biodiverse ecosystems, whose inhabitants must be empowered. Deserts are commonly imagined as barren, defiled, worthless places, wastelands in need of development. This understanding has fueled extensive anti-desertification efforts—a multimillion-dollar global campaign driven by perceptions of a looming crisis. In this book, Diana Davis argues that estimates of desertification have been significantly exaggerated and that deserts and drylands—which constitute about 41% of the earth's landmass—are actually resilient and biodiverse environments in which a great many indigenous people have long lived sustainably. Meanwhile, contemporary arid lands development programs and anti-desertification efforts have met with little success. As Davis explains, these environments are not governed by the equilibrium ecological dynamics that apply in most other regions. Davis shows that our notion of the arid lands as wastelands derives largely from politically motivated Anglo-European colonial assumptions that these regions had been laid waste by “traditional” uses of the land. Unfortunately, such assumptions still frequently inform policy. Drawing on political ecology and environmental history, Davis traces changes in our understanding of deserts, from the benign views of the classical era to Christian associations of the desert with sinful activities to later (neo)colonial assumptions of destruction. She further explains how our thinking about deserts is problematically related to our conceptions of forests and desiccation. Davis concludes that a new understanding of the arid lands as healthy, natural, but variable ecosystems that do not necessarily need improvement or development will facilitate a more sustainable future for the world's magnificent drylands.

Book Description
First published in 1995. This title presents the proceedings of The Second International Conference on Range Management in the Arabian Gulf, 1990. The objectives of the Conference were to: evaluate progress made following the First Conference; exchange information on range management development; review advances in applicable technologies; discuss potential strategies for range enhancement and assemble pertinent recommendations for enactment. As such, these proceedings will serve as a reference base for researchers, professors, lecturers, and students alike, both at advanced undergraduate and graduate levels.

Book Description
Controversial, and often discussed with passion and vehemence, desertification is a problem on whose solution the survival of millions of humans is dependent. This book aims at an understanding of what is commonly called "desertification" - a term which has a connotation of irreversibility, spreading and emergence of desert-like landscapes: "land degradation" is proposed to replace it. The purpose is to present what has happened in reality, and what might be done. Illustrative worldwide analyses allow a more realistic evaluation of global land degradation. Each level of technology, excessive or insufficient, creates its own mismanagement. This is reflected in a decrease in soil productivity and eventually land degradation. The benefit to the reader is an awareness of the ecozones which have undergone the most severe land degradation, and a global overview of the phenomena, mechanisms and existing solutions.
