This book was released on 2019-05-16 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.

Book Synopsis Imperial Gullies by : Kate Barger Showers
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 Marginality written by Joachim von Braun and published by Springer. This book was released on 2013-08-19 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book takes a new approach on understanding causes of extreme poverty and promising actions to address it. Its focus is on marginality being a root cause of poverty and deprivation. “Marginality” is the position of people on the edge, preventing their access to resources, freedom of choices, and the development of capabilities. The book is research based with original empirical analyses at local, national, and local scales; book contributors are leaders in their fields and have backgrounds in different disciplines. An important message of the book is that economic and ecological approaches and institutional innovations need to be integrated to overcome marginality. The book will be a valuable source for development scholars and students, actors that design public policies, and for social innovators in the private sector and non-governmental organizations.
Book Synopsis Combating Desertification in Asia, Africa and the Middle East by : G. Ali Heshmati
Download or read book Combating Desertification in Asia, Africa and the Middle East written by G. Ali Heshmati and published by Springer Science & Business Media. This book was released on 2013-07-01 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the ‘how’ of desertification control as opposed to an analysis of the ‘why’ and fills a gap in the desertification-related literature in that it shows what to do in situations ranging from fixing mobile sands to arresting accelerated soil erosion in sloping lands. There are numerous illustrations to show the successful techniques. This compilation demonstrates that desertification and land degradation can be controlled and reversed with existing techniques in such widely varying environments as the Sahel of Africa to Sri Lanka and the Philippines in SE Asia, from mountains in Lesotho to low lands on desert margins in Mongolia. Proven approaches include technical interventions, changes in governance and to the legislative framework and policy reform. The book fills a gap in the desertification-related literature in that it shows what to do in situations ranging from fixing mobile sands to arresting accelerated soil erosion in sloping lands.

Book Synopsis Land and Sustainable Development in Africa by : Kojo Sebastian Amanor
Download or read book Land and Sustainable Development in Africa written by Kojo Sebastian Amanor and published by Bloomsbury Publishing. This book was released on 2008-07-15 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book links contemporary debates on land reform with wider discourses on sustainable development within Africa. Featuring chapters and in-depth case studies on South Africa and Zimbabwe, Malawi, Kenya, Botswana and West Africa, it traces the development of ideas about sustainable development and addresses a new agenda based on social justice. The authors critically examine contemporary neoliberal market-led reforms and the legacy of colonialism on the land question. They argue that debates on sustainable development should be placed in the context of structural interests, access and equity, rather than technical management of land and resources. Additionally, they show that these structural factors cannot be transformed by institutional reform based on notions of elective democracy, community participation, and market-reform, but require a far more radical programme to redress the injustices of the colonial system that continue today. The book advocates a commitment to building sustainable livelihoods for farmers, calling for a redistribution of land and natural resources to challenge existing economic relations and frameworks for development.

Book Synopsis Why Evolution is True by : Jerry A. Coyne
Download or read book Why Evolution is True written by Jerry A. Coyne and published by OUP Oxford. This book was released on 2010-01-14 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: For all the discussion in the media about creationism and 'Intelligent Design', virtually nothing has been said about the evidence in question - the evidence for evolution by natural selection. Yet, as this succinct and important book shows, that evidence is vast, varied, and magnificent, and drawn from many disparate fields of science. The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology, geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution.

Book Synopsis Soil Degradation and Restoration in Africa by : Rattan Lal
Download or read book Soil Degradation and Restoration in Africa written by Rattan Lal and published by CRC Press. This book was released on 2019-07-09 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation is a widespread problem in Africa resulting in decreased agricultural productivity while demand for food continues to increase. Degradation is caused by accelerated erosion, acidification, contamination, depletion of soil organic matter and plant nutrients, and salinization. The major cause of soil degradation in Africa is uncontrolled and excessive grazing in the savanna regions followed by deforestation and the use of inappropriate and extractive farming practices. Perpetual neglect of the health of soils in Africa can exacerbate the already serious problems of food and nutritional insecurity and environmental degradation. Food and nutritional security of the growing population of Africa can only be achieved if degraded soils are restored and soils of agroecosystems are managed prudently and sustainably. Ignoring soils and taking the fragile, finite and precious soil resources for granted is the principal cause of poverty, hunger, and environmental degradation. The downward spiral must be reversed through soil restoration measures based on translating science into action. This book describes the soils of Africa, processes of soil degradation, extent and severity of soil degradation, and the impacts of degradation processes on food and nutritional security. Features: Explores the extent and severity of soil degradation in Africa Analyzes the cause–effect relationship between anthropogenic activities and soil degradation Reviews processes of soil degradation in Africa including erosion, salinization, nutrient depletion, and decline of soil organic matter Addresses the effect of climate change on soil degradation in Africa. Explains how soil degradation causes food and nutritional insecurity Part of the Advances in Soil Sciences series, this volume is specifically devoted to the processes and factors that cause soil degradation and the challenges and potential for remediation and restoration of soil health in Africa.
Download or read book Nature Divided written by Timm Hoffman and published by Juta. This book was released on 2001 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the same way that South Africa's people were divided along racial lines, so too was its landscape - into the predominantly communally farmed lands of the homelands and self-governing territories, and commercial farming areas. These divisions, reflected both in former government policy and local practice, have profoundly affected land degradation in South Africa. This book, the product of extensive research, is based on a landmark report on land degradation arising from South Africa's commitment to the UN Convention to Combat Desertification. It reflects the first complete assessment of South Africa's land degradation problem, taking into account not only agricultural and ecological concerns, but also the socio-political and historical contexts. It places previously unavailable information in the hands of those who need it most - politicians, agricultural extension officers, and communal and commercial farmers. It will also be of interest to students and teachers. At once sobering, challenging and optimistic, this book is a call to action. It shows that we are all affected by the extent of land degradation in South Africa.

Book Synopsis Advances in Soil Science by : J.K. Cronk
Download or read book Advances in Soil Science written by J.K. Cronk and published by Springer. This book was released on 1991-12-03 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation is clearly one of the most pressing problems facing man kind. A continuation of soil degradation will eventually lead to a loss in crop productivity even though fertilizers and other inputs often result in increased yields in the short term. Soil degradation also leads to environ mental pollution. A decrease in soil quality invariably leads to a decrease in water quality, and often in air quality. While there is a clear consensus that soil degradation is a major problem, the literature on this subject leaves numerous baffling questions. If statis tics on land degradation are correct, there is a definite cause for concern, and present a mammoth challenge for agricultural scientists. There are those that say the scientific community has over dramatized this issue, and created a credibility problem. Consequently; Volume 11 of Advances in Soil Science was organized by Dr. Rattan Lal who is recognized as a lead ing authority on the subject. The objective of Volume 11 was to assess the types and processes of soil degradation and establish some of the major cause-effect relationships. Volume II documented the seriousness of soil degradation in many parts of the world. Therefore, it seemed immediately important to devote a volume to the principles and technologies for restor ing degraded soils to a productive status. While the land resources are limited, world population is rapidly increasing, particularly in developing countries. Dr.
