Man-made Deserts


Book Description

The history of civilizations is a record of struggles against the progressive dessication of civilized lands. The more ancient the civilization, the drier and more wasted, usually, is the supporting country.




Aralkum - a Man-Made Desert


Book Description

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.




Sustainable Land Use in Deserts


Book Description

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.




The Arid Lands


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.




Climate Change in Deserts


Book Description

A synthesis of the environmental and climatic history of every major desert and desert margin, for researchers and advanced students.




Desert Edens


Book Description

How technological advances and colonial fears inspired utopian geoengineering projects during the late nineteenth and early twentieth centuries From the 1870s to the mid-twentieth century, European explorers, climatologists, colonial officials, and planners were avidly interested in large-scale projects that might actively alter the climate. Uncovering this history, Desert Edens looks at how arid environments and an increasing anxiety about climate in the colonial world shaped this upsurge in ideas about climate engineering. From notions about the transformation of deserts into forests to Nazi plans to influence the climates of war-torn areas, Philipp Lehmann puts the early climate change debate in its environmental, intellectual, and political context, and considers the ways this legacy reverberates in the present climate crisis. Lehmann examines some of the most ambitious climate-engineering projects to emerge in the late nineteenth and early twentieth centuries. Confronted with the Sahara in the 1870s, the French developed concepts for a flooding project that would lead to the creation of a man-made Sahara Sea. In the 1920s, German architect Herman Sörgel proposed damming the Mediterranean in order to geoengineer an Afro-European continent called “Atlantropa,” which would fit the needs of European settlers. Nazi designs were formulated to counteract the desertification of Eastern Europe and Central Asia. Despite ideological and technical differences, these projects all incorporated and developed climate change theories and vocabulary. They also combined expressions of an extreme environmental pessimism with a powerful technological optimism that continue to shape the contemporary moment. Focusing on the intellectual roots, intended effects, and impact of early measures to modify the climate, Desert Edens investigates how the technological imagination can be inspired by pressing fears about the environment and civilization.




The Immeasurable World


Book Description

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.




Deserts on the March


Book Description

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."




When the Sahara Was Green


Book Description

The little-known history of how the Sahara was transformed from a green and fertile land into the largest hot desert in the world The Sahara is the largest hot desert in the world, equal in size to China or the United States. Yet, this arid expanse was once a verdant, pleasant land, fed by rivers and lakes. The Sahara sustained abundant plant and animal life, such as Nile perch, turtles, crocodiles, and hippos, and attracted prehistoric hunters and herders. What transformed this land of lakes into a sea of sands? When the Sahara Was Green describes the remarkable history of Earth’s greatest desert—including why its climate changed, the impact this had on human populations, and how scientists uncovered the evidence for these extraordinary events. From the Sahara’s origins as savanna woodland and grassland to its current arid incarnation, Martin Williams takes us on a vivid journey through time. He describes how the desert’s ancient rocks were first fashioned, how dinosaurs roamed freely across the land, and how it was later covered in tall trees. Along the way, Williams addresses many questions: Why was the Sahara previously much wetter, and will it be so again? Did humans contribute to its desertification? What was the impact of extreme climatic episodes—such as prolonged droughts—upon the Sahara’s geology, ecology, and inhabitants? Williams also shows how plants, animals, and humans have adapted to the Sahara and what lessons we might learn for living in harmony with the harshest, driest conditions in an ever-changing global environment. A valuable look at how an iconic region has changed over millions of years, When the Sahara Was Green reveals the desert’s surprising past to reflect on its present, as well as its possible future.
