Download or read book The Arid Lands written by Diana K. Davis and published by MIT Press. This book was released on 2016-03-25 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Afforestation in Arid Zones written by R.N. Kaul and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing world population is already causing intensive pressure on the most productive areas of the earth's surface. Hopes of improved living standards, if realised, will increase the pressure still further. The need to make better use of less productive areas thus becomes an urgent priority for human endeavour. In this respect, the arid and semi-arid regions of the world, occupying about 11,000 million acres or 4,500 million hectares, roughly one third of the tota11and surface, pose a constant challenge to man's technological skill. Though the possibilities of economic use of the real deserts are inherently limited, there remain vast areas with less extreme conditions where sustained research is capable of yielding substantial gains in pro ductivity. The problem is so large that it can be solved only by the coordinated efforts of workers in many countries and many disciplines. Forestry has a special part to play, not only for its potential value for wood production but still more for the beneficial effects of shelter from desiccating winds which so commonly accompany arid conditions. Mr. KA UL is to be congratulated on his initiative to pool the results of research on afforestation in arid zones in many parts of the world, and to present them in a single volume in the form of separate monographs.

Book excerpt: The international conference Arid Lands: Today and Tomorrow drew more than 400 participants from over 3 S countries to Tucson, Arizona, for one week in October of 19 8 S. The diversity of presenters, disciplines and subject matters addressed contributed to an interesting and informative conference. The papers presented in this volume represent the efforts of scientists and other individuals who, through their various disciplines, are addressing the problems of and opportunities presented by the arid lands of the world. A committee of five scientists reviewed for substance. relevance and their contribution to the conference the 284 abstracts that were submitted. They selected 146 for presentation at the conference and of those papers presented, 128 were received for inclusion in the proceedings.
Download or read book The Postwar Origins of the Global Environment written by Perrin Selcer and published by Columbia University Press. This book was released on 2018-09-25 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the wake of the Second World War, internationalists identified science as both the cause of and the solution to world crisis. Unless civilization learned to control the unprecedented powers science had unleashed, global catastrophe was imminent. But the internationalists found hope in the idea of world government. In The Postwar Origins of the Global Environment, Perrin Selcer argues that the metaphor of “Spaceship Earth”—the idea of the planet as a single interconnected system—exemplifies this moment, when a mix of anxiety and hope inspired visions of world community and the proliferation of international institutions. Selcer tells the story of how the United Nations built the international knowledge infrastructure that made the global-scale environment visible. Experts affiliated with UN agencies helped make the “global”—as in global population, global climate, and global economy—an object in need of governance. Selcer traces how UN programs such as UNESCO’s Arid Lands Project, the production of a soil map of the world, and plans for a global environmental-monitoring system fell short of utopian ambitions to cultivate world citizens but did produce an international community of experts with influential connections to national governments. He shows how events and personalities, cultures and ecologies, bureaucracies and ideologies, decolonization and the Cold War interacted to make global knowledge. A major contribution to global history, environmental history, and the history of development, this book relocates the origins of planetary environmentalism in the postwar politics of scale.

This book was released on 2007-12-07 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Future of Arid Lands, edited by Gilbert White and published in 1956, comprised papers delivered at the "International Arid Lands Meetings" held in New Mexico in 1955. At these meetings, experts considered the major issues then confronting the world’s arid lands and developed a research agenda to address these issues. This book reexamines this earlier work and explores changes in the science and management of arid lands over the past 50 years within their historical contexts.

This book was released on 2021-07-26 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the most recent innovative studies in the field of water resources for arid areas to move towards more sustainable management of the resources. It gathers outstanding contributions presented at the 2nd International Water Conference on Water Resources in Arid Areas (IWC), which was held online (Muscat, Oman) in November 2020. Papers discuss challenges and solutions to alleviate water resource scarcity in arid areas, including water resources management, the introduction of modern irrigation systems, natural groundwater recharge, construction of dams for artificial recharge, use of treated wastewater, and desalination technologies. As such, the book provides a platform for the exchange of recent advances in water resources research, which are essential to improving the critical water situation and to move towards more sustainable management of water resources.
