Available in PDF, EPUB and Kindle. Book excerpt: It now seems incontrovertible (as Alessandra Giannini has demonstrated) that the series of Sahelian droughts that began in the early 1970s were driven by changes in sea surface temperatures and that they were not caused by local land use mismanagement in the Sahel itself. Combined with the apparent re-greening of the Sahel, these findings effectively close a long-standing policy and scientific debate (in which the lead authors of this book participated) on the causes and extent of desertification in the Sahel. The opportunity now presents itself to treat this debate as a historical object lesson in the relationship between science, the formation of public opinion, and international policy-making in the context of climate change. In short, what might the ‘great Sahelian desertification boondoggle’ have to tell us about current attempts to come to grips with climate change?

Book excerpt: This book (with a foreword by eminent desertification specialist, Dr. Alan Grainger of Leeds University) provides a synthesis of what desertification means in the present day context of worldwide concerns about land degradation in the face of global (including climate) change, burgeoning populations, urbanization, and loss of biodiversity. It defines and describes desertification in its many forms and examines efforts to combat land degradation. The authors present some models that relate to the current impact of climate change on desertification as well as the medium to long term, and offer case studies on efforts to combat desertification in the major regions of the world. In the last chapter, we attempt to synthesize the whole book in the context of the post-2015 agreements on climate change (the Paris Accord) and the UN Sustainable Development Goals (SDG). Chapters concerning the historical context of desertification consider the definition and meanings associated with the word desertification; discuss the global extent and severity of the many types of desertification; and explain the current status of desertification in the post-2015 context. The book also discusses the impacts of desertification on ecosystems and people along with biodiversity; dust and sand storms from desertified landscapes; and the people affected by desertification. Chapters also focus on desertification and climate change, and consider the nexus between climate, soil, water and people; climate variability, land use and livelihoods affected by desertification are also analyzed. Chapters on combating desertification focus on combating desertification and act as an overview of proven practices with a detailed case study from China. Finally, synthesis and conclusions are consider the future of those affected by desertification, dealing firstly with medium to long term future outlooks and secondly with attempting to sum up the trends.
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.
Download or read book The Causes and Progression of Desertification written by Helmut Geist and published by Routledge. This book was released on 2017-09-08 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an examination into the causes and prospects of desertification through a systematic review of 132 sub national case studies. It uses a meta-analytical model to determine whether proximate causes and underlying driving forces fall into any patterns, to identify mediating factors, feedbacks, cross-scalar dynamics and typical pathways. It shows a limited set of recurrent core variables in varying combinations to drive desertification. Most prominent root causes are climatic factors, institutions, national policies, population growth and remote economic influences that lead to local cropland expansion, overgrazing and infrastructure extension, associated with desertification as a potential but not necessary outcome. Some factors are geographically robust; most of them are region and time specific.

Download or read book Land Surface Remote Sensing written by Mehrez Zribi and published by Elsevier. This book was released on 2016-11-08 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land Surface Remote Sensing: Environment and Risks explores the use of remote sensing in applications concerning the environment, including desertification and monitoring deforestation and forest fires. The first chapter covers the characterization of aerosols and gases by passive remote sensing. The next chapter presents the correlation of optical images for quantifying the deformation of the Earth's surface and geomorphological processes. The third chapter is examines remote sensing applications in the mining environment. The fourth chapter depicts the strong potential of radar imagery for volcanology and urban and mining subsidence studies. The next two chapters deal respectively with the use of remote sensing in locust control and the contribution of remote sensing to the epidemiology of infectious diseases. In the last ten years, spatial observation of the Earth—particularly continental surfaces—has expanded considerably with the launch of increasing numbers of satellites covering various applications (hydrology, biosphere, flow of surface, snow, ice, landslide, floods). This has paved the way for an explosion in the use of remote sensing data. This book offers essential coverage of space-based observation techniques for continental surfaces. The authors explore major applications and provide a corresponding detailed chapter for the physical principles, physics of measurement, and data processing requirements for each technique, bringing you up-to-date descriptions of techniques used by leading scientists in the field of remote sensing and Earth observation. - Provides clear and concise descriptions of modern remote sensing methods - Explores the most current remote sensing techniques with physical aspects of the measurement (theory) and their applications - Provides chapters on physical principles, measurement, and data processing for each technique described - Describes optical remote sensing technology, including a description of acquisition systems and measurement corrections to be made

Download or read book Drought written by Ben Cook and published by Columbia University Press. This book was released on 2019-04-30 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is fundamental to all life. From the Dust Bowl of the 1930s, to the extreme water shortages that have struck California in recent years, modern societies often take its abundance for granted until it unexpectedly becomes scarce. Drought is one of the many problems anthropogenic climate change may exacerbate, but it is also a complex phenomenon at the intersection of a range of scientific disciplines and public policy issues. In this innovative book, Benjamin I. Cook brings together climate science, hydrology, and ecology to provide a synthetic overview of drought and its environmental and social consequences. Cook introduces readers to the hydroclimate and its components, explaining the global water cycle, the earth’s climate system, and the distribution of water resources. He discusses drought dynamics and variability over time, the climatological context and ecological effects, and environmental issues such as desertification, land degradation, and groundwater depletion. He also considers the socioeconomic impacts of drought and the role of drought risk management policy, especially in light of how climate change is expected to affect drought risk and severity. Cook gives special attention to paleoclimate and the role of drought in the crises of ancient civilizations. A scientifically comprehensive and approachable overview of water issues throughout the world, Drought is a critical interdisciplinary text that will be essential reading for a broad range of students in earth science and environmental and sustainability studies.
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.

This book was released on 2008-11-27 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work becomes with methodological rigor a part of the innovative proposals for the characterization of the areas at risk of desertification. The complexity of the phenomenon of desertification, which involves extended surfaces in all continents, is one of the most alarming processes of the environmental degradation of our Planet and threatens the health and the living conditions of over a billion of persons. The food crisis, in continuous increase, ask for the world of research to urgently supply reassuring solutions concerning the acquisition of indicators, which are easy to monitor and concur to control the phenomenon in order to fight its acceleration. The constant but different combination that determines the diffusion of deserti- cation in the territories, attributable mostly to climatic changes and the activities of the man, makes our job challenging and complicated, since it varies from region to region. We are aware of all this and therefore we think that the methodological approach of survey of the data is an extremely important element to locate of the phenomenon and to monitor its course. This work, which is characterized for its multi-disciplinary approach, suggests solutions that we wish will quickly find concrete applications at international level.

Download or read book Desertification Land Degradation and Sustainability written by Anton Imeson and published by John Wiley & Sons. This book was released on 2011-12-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desertification offers a comprehensive overview of the subject and clearly emphasizes the link between local and global desertification processes and how past and current policy has affected arid environments and their populations. This text adequately applies the research undertaken during the last 15 years on the topic. Desertification has become increasingly politicized and there is a need to present and explain the facts from a global perspective. This book tackles the issues surrounding desertification in a number of ways from differing scales (local to global), processes (physical to human), the relationship of desertification to current global development and management responses at different scales. Desertification has been mainstreamed and integrated into other areas of concern and has consequently been ignored as a cross cutting issue. The book redresses this balance. Making use of much original data and information that has been undertaken by many scientists andpractitioners during the last decade in different parts of the world, Desertification, Land Degradation and Sustainability is organised according to the principles of adaptive management and hierarchy theory and clearly explains desertification within a framework of evolving and interacting physical and socio-economic systems. In addition to research data the book also draws from the National Action Plans of different countries, the IPCC Fourth Assessment on Climate Change and the Millennium assessments. Clearly structured throughout, the content of the book is organised at different scales; local, regional and global. It also specifically explains processes linking top-down and bottom- up interactions and has a strong human component. The historical, cultural and physical context is also stressed. Clearly organised into the following distinct sections: a) Concepts and processes b) Data c) Impacts d) Responses e) Case studies. This text is essential for anyone studying desertification as part of an earth and environmental science degree.
