Download or read book Aralkum a Man Made Desert written by Siegmar-W. Breckle and published by Springer Science & Business Media. This book was released on 2011-09-22 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having been the fourth largest lake on the globe roughly 50 years ago, today the Aral Sea no longer exists. Human activities caused its desiccation and the formation of a huge new desert, the Aralkum, which can be regarded as one of the greatest ecological catastrophes and - at the same time - the largest primary succession experiment of mankind. This volume brings together the results of international and interdisciplinary long-term studies on the new desert ecosystem and is divided into four main sections. The first section provides an overview of the physical characteristics of the area and covers geological, pedological, geomorphological and climatological aspects and their dynamics, especially dust-storm dynamics. The second focuses on the biotic aspects and highlights the spatial and temporal patterns of the flora and fauna. In the third section studies and projects aiming to combat desertification by phytomelioration and to develop strategies for the conservation of biodiversity are presented. The book is rounded off with a section providing a synthesis and conclusions.
Download or read book Sustainable Land Use in Deserts written by Siegmar-W. Breckle and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Deserts and Desertification written by Yajuan Zhu and published by BoD – Books on Demand. This book was released on 2022-02-16 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: A desert is an ecosystem in an arid zone in which sand dunes cover the land and sandstorms often occur. Although desert vegetation is sparse, it plays an important role in ecosystem structure and function. Desertification is one of the most severe environmental problems today. Land desertification can be controlled through many measures, such as eco-villages, eco-agriculture, biodiversity conservation, and the combination of engineering and biology. This edited volume provides new insights into the pattern of desert ecosystems and the progress of desertification control. It is a useful resource for researchers in ecology, forestry, and land desertification control.

Download or read book Climate Change in Deserts written by Martin Williams and published by Cambridge University Press. This book was released on 2014-08-11 with total page 653 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reconstructing climatic changes in deserts and their margins at a variety of scales in space and time, this book draws upon evidence from land and sea, including desert dunes, wind-blown dust, river and lake sediments, glacial moraines, plant and animal fossils, isotope geochemistry, speleothems, soils, and prehistoric archaeology. The book summarises the Cenozoic evolution of the major deserts of the Americas, Eurasia, Africa and Australia, and the causes of historic floods and droughts. The book then considers the causes and consequences of desertification and proposes four key conditions for achieving ecologically sustainable use of natural resources in arid and semi-arid areas. Climate Change in Deserts is an invaluable reference for researchers and advanced students interested in the climate and geomorphology of deserts: geographers, geologists, ecologists, archaeologists, soil scientists, hydrologists, climatologists and natural resource managers.
Download or read book War of a Thousand Deserts written by Brian DeLay and published by Yale University Press. This book was released on 2008-11-01 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1830s, after decades of relative peace, northern Mexicans and the Indians whom they called "the barbarians" descended into a terrifying cycle of violence. For the next fifteen years, owing in part to changes unleashed by American expansion, Indian warriors launched devastating attacks across ten Mexican states. Raids and counter-raids claimed thousands of lives, ruined much of northern Mexico's economy, depopulated its countryside, and left man-made "deserts" in place of thriving settlements. Just as important, this vast interethnic war informed and emboldened U.S. arguments in favor of seizing Mexican territory while leaving northern Mexicans too divided, exhausted, and distracted to resist the American invasion and subsequent occupation. Exploring Mexican, American, and Indian sources ranging from diplomatic correspondence and congressional debates to captivity narratives and plains Indians' pictorial calendars, "War of a Thousand Deserts" recovers the surprising and previously unrecognized ways in which economic, cultural, and political developments within native communities affected nineteenth-century nation-states. In the process this ambitious book offers a rich and often harrowing new narrative of the era when the United States seized half of Mexico's national territory.
Download or read book Aeolian Processes as Dust Storms in the Deserts of Central Asia and Kazakhstan written by Gulnura Issanova and published by Springer. This book was released on 2017-01-09 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the aeolian processes in the desert zone of Kazakhstan and Central Asian Deserts, and analyzes the current status of dust and sand storms in Central Asia and Kazakhstan. It also highlights the analyses, dynamics and long-term observations of storms on the basis of numerous cartographic materials and satellite images. Dust/sand storms are a common and important phenomenon in the arid and semi-arid regions of Kazakhstan and Central Asia as well,especially in its southern parts, where areas are covered by a great variety of deserts and offer a significant source of mineral and salt aerosols. The deserts of Kazakhstan mostly cover lowlands and extend from the eastern coast of the Caspian Sea to the piedmonts of the Tien-Shan Mountain. In Kazakhstan and Central Asia desertification processes due to wind erosion in the form of dust/sand storms were observed in semi-desert and desert landscapes.

Book excerpt: Winner of the Stanford Dolman Travel Book of the Year (UK) "William Atkins is an erudite writer with a wonderful wit and gaze and this is a new and exciting beast of a travel book."—Joy Williams In the classic literary tradition of Bruce Chatwin and Geoff Dyer, a rich and exquisitely written account of travels in eight deserts on five continents that evokes the timeless allure of these remote and forbidding places. One-third of the earth's surface is classified as desert. Restless, unhappy in love, and intrigued by the Desert Fathers who forged Christian monasticism in the Egyptian desert, William Atkins decided to travel in eight of the world's driest, hottest places: the Empty Quarter of Oman, the Gobi Desert and Taklamakan deserts of northwest China, the Great Victoria Desert of Australia, the man-made desert of the Aral Sea in Kazkahstan, the Black Rock and Sonoran Deserts of the American Southwest, and Egypt's Eastern Desert. Each of his travel narratives effortlessly weaves aspects of natural history, historical background, and present-day reportage into a compelling tapestry that reveals the human appeal of these often inhuman landscapes.
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 The End of Desertification written by Roy H. Behnke and published by Springer. This book was released on 2016-04-12 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question in the title of this book draws attention to the shortcomings of a concept that has become a political tool of global importance even as the scientific basis for its use grows weaker. The concept of desertification, it can be argued, has ceased to be analytically useful and distorts our understanding of social-environmental systems and their resiliency, particularly in poor countries with variable rainfall and persistent poverty. For better policy and governance, we need to reconsider the scientific justification for international attempts to combat desertification. Our exploration of these issues begins in the Sahel of West Africa, where a series of severe droughts at the end of the 20th century led to the global institutionalization of the idea of desertification. It now seems incontrovertible that these droughts were not caused primarily by local land use mismanagement, effectively terminating a long-standing policy and scientific debate. There is now an opportunity to treat this episode as an object lesson in the relationship between science, the formation of public opinion and international policy-making. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept. Despite an increasingly sophisticated understanding of dryland environments and societies, the uses now being made of the desertification concept in parts of Asia exhibit many of the shortcomings of earlier work done in Africa. It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. This book is an effort to critically examine that experience and accelerate the learning process in other parts of the world.

Download or read book Deserts on the March written by Paul Bigelow Sears and published by . This book was released on 1935 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1935, when Paul Sears set out to write his book Deserts on the March, drought gripped much of the United States, and the Dust Bowl was at its worst. Great dust clouds were blowing as far east as New York and Washington, D.C. The publication of Deserts on the March had a profound impact in awakening America to the task of controlling soil erosion through proper land management and understanding of ecological relationships.Today, global desertification and deforestation continue on a grand scale. Each year about 42,000 square miles of forests are lost -- an area the size of Tennessee. International studies show that desertification -- the expansion of desert-like landscapes into semi-arid environments due to the impact of human influences -- now threatens about one-third of the world's land surface and affects the livelihoods of at least 850 million people.The great strength of Deserts on the March does not lie so much in its precise predictions or policy prescriptions. Rather, this beautifully written book should be read for Sears' ecological wisdom and his sweeping story of man's destruction of the earth."
