Download or read book Martian Gullies and their Earth Analogues written by S.J. Conway and published by Geological Society of London. This book was released on 2019-01-21 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gullies on Mars resemble terrestrial gullies involved in the transport of abundant material down steep slopes by liquid water. However, liquid water should not be stable at the Martian surface. The articles in this volume present the two main opposing theories for Martian gully formation: climate-driven melting of surficial water-ice deposits and seasonal dry-ice sublimation. The evidence presented ranges from remote-sensing observations, to experimental simulations, to comparison with Earth analogues. The opposing hypotheses imply either that Mars has been unusually wet in the last few million years or that it has remained a cold dry desert – both with profound implications for understanding the water budget of Mars and its habitability. The debate questions the limits of remote-sensing data and how we interpret active processes on extra-terrestrial planetary surfaces, even beyond those on Mars, as summarized by the review paper at the beginning of the book.
Download or read book Imperial Gullies written by Kate Barger Showers and published by Ohio University Press. This book was released on 2005 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once the grain basket for South Africa, much of Lesotho has become a scarred and treeless wasteland. The nation's spectacular gullying has concerned environmentalists and conservationists for more than half a century, In Imperial Gullies: Soil Erosion and Conservation in Lesotho, Kate B. Showers documents the truth behind this devastation. Showers reconstructs the history of the landscape, beginning with a history of the soil. She concludes that Lesotho's distinctive erosion chasms, called dongas, often cited as an example of destructive land-use practices by African farmers, actually were caused by colonial and postcolonial practices. The residents of Lesotho emerge as victims of a failed technology. Their efforts to mitigate or resist implementation of destructive soil conservation engineering works were thwarted, and they were blamed for the consequences of policies promoted by international soil conservationists since the 1930s. Imperial Gullies calls for an observational, experimental and, most importantly, a fully consultative and participatory approach to address Lesotho's serious contemporary problems of soil erosion. The first book to bring to center stage the historical practice of colonial soil science and a cautionary tale of western science in unfamiliar terrain it will interest a broad, interdisciplinary audience in African and environmental studies, social sciences, and history. "Showers shows how local people understood that colonial contour conservation methods and road building actually stimulated gully erosion, something colonial scientists failed to realize. Overall it is undoubtedly one of the most important books written to date on any part of the environmental history of Africa. Moreover it stands out in the discipline of environmental history in general as an unusually sophisticated work of great insight and explanatory power."---Richard H. Grove, author of Green Imperialism: Colonial Expansion, Tropical Island Edens and the Origins of Environmentalism, 1600-1860 Kate B. Showers is a visiting research fellow and senior research associate at the Centre for World Environmental History, University of Sussex, England. She has lived in rural Lesotho and has served as head of research, Institute of Southern African Studies, National University of Lesotho.

Download or read book Gully Erosion Studies from India and Surrounding Regions written by Pravat Kumar Shit and published by Springer Nature. This book was released on 2019-11-19 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers the scientific basis for the ample evaluation of badland management in India and some surrounding regions. It examines the processes operating in the headwaters and main channels of ephemeral rivers in lateritic environments of India. In particular, the book covers a range of vital topics in the areas of gully erosion and water to soil erosion at lateritic uplands regions of India and other regions in Asia. It explores the probable gully erosion modeling through Remote Sensing & GIS Techniques. It is divided into three units. Unit I deals with the introduction of badland, types of badland and the process of badland formation. Unit II is devoted to a description of quantitative measurements. Unit III deals with the control and management processes related to various issues from different regions. As such this book serves as a reference book for research activities in this area. It is an efficient guide for aspiring researchers in applied geography, explaining advanced techniques to help students recognize both simple and complex concepts.
