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 When the Sahara Was Green written by Martin Williams and published by Princeton University Press. This book was released on 2021-10-05 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Green State in Africa written by Carl Death and published by Yale University Press. This book was released on 2016-09-27 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: A provocative reassessment of the relationship between states and environmental politics in Africa From climate-related risks such as crop failure and famine to longer-term concerns about sustainable urbanization, environmental justice, and biodiversity conservation, African states face a range of environmental issues. As Carl Death demonstrates, the ways in which they are addressing them have important political ramifications, and challenge current understandings of green politics. Death draws on almost a decade of research to reveal how central African environmental politics are to the transformation of African states.
Download or read book Africa the Devastated Continent written by A. de Vos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa is not known as one of the more densely populated continents. Yet, the damaging marks of man's activities may be seen there dramatically. Many of Africa's ecological zones are fragile. Large scale soil erosion, resul tant cycles of drought and flash floods, downgrading of fauna and flora are well-known to many in general ways, as well as from detailed examination of a few areas. But large parts of Africa remain inaccessible. Very few students of Africa have the opportunity - or the tenacity - to travel over these vast areas or into the hidden corners that lie beyond the well-known routes of Africa. As FAO's Regional Wildlife and National Parks Officer for Africa, ANTooN DE Vos had the opportunity of travelling widely and studying and reporting on the acceleration of man-made changes in much of the continent. As an experienced practitioner of an important and difficult science, ecology, he has made a significant professional contribution with this book. It is our hope that those who read it will be encouraged to carryon the important work and the concern with this subject to which Dr. DE Vos has devoted so much of his knowledge, energy and personal commitments.
Download or read book Chaos in the Heavens written by Jean-Baptiste Fressoz and published by Verso Books. This book was released on 2024-03-12 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: "If you want to understand the long path to the climate crisis, read this book." –Deborah Coen, Professor of History and the History of Science and Medicine, Yale University Politicians and scientists have debated climate change for centuries in times of rapid change Nothing could seem more contemporary than climate change. Yet, in Chaos in the Heavens, Jean-Baptiste Fressoz and Fabien Locher show that we have been thinking about and debating the consequences of our actions upon the environment for centuries. The subject was raised wherever history accelerated: by the Conquistadors in the New World, by the French revolutionaries of 1789, by the scientists and politicians of the nineteenth century, by the European imperialists in Asia and Africa until the Second World War. Climate change was at the heart of fundamental debates about colonisation, God, the state, nature, and capitalism. From these intellectual and political battles emerged key concepts of contemporary environmental science and policy. For a brief interlude, science and industry instilled in us the reassuring illusion of an impassive climate. But, in the age of global warming, we must, once again, confront the chaos in the heavens.
Download or read book The Arid Frontier written by Hendrik J. Bruins and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Pastoral Continuum written by Paul Spencer and published by Clarendon Press. This book was released on 1998-01-29 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paul Spencer presents the definitive study of the ways of life of the cattle-herding peoples of East Africa, drawing on many years of research. This region has offered a prime example of a traditional culture resisting the inevitability of change; it provides the best-known and most extensive instance both of cattle-pastoralist society and of social organization based primarily on age. Pastoral peoples were once dominant in the East African interior, but development of the market economy has progressively polarized the region and forced them into the most marginal, drought-ridden areas; in this ecological trap they have become a peripheral underclass. The Pastoral Continuum examines the richness and resilience of their cultures and illuminates the role of indigenous practices and institutions in adaptation and survival. The pastoralists' systems of age organization in particular are notable for their resilience: it is demonstrated that these are bound up with problems of growth and succession in family enterprises, and that marriage is a critical link in the web of alliance that governs the problematic relations between old and young. Spencer's exploration of the development of the pastoralist phenomenon yields a unique view of its place in the modern world and its prospects for the future. This landmark work by a leading authority will be of lasting value to any reader interested in traditional social systems of this kind.

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.
