Book Synopsis Physics of desertification by : F. El-Baz
Download or read book Physics of desertification written by F. El-Baz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deserts are parts of the Earth that receive little or no rain; 25 cm or less per year. The physical processes that act upon these parched lands are vastly different from those that shape the more humid parts of the terrestrial landmasses. In the desert, wind is a major agent of erosion and transportation. As the results of recent space missions have indicated, this is also true in the case of the planet Mars. Thus, our understanding of desert processes sheds light on fundamental planetary processes that may apply on any planetary body that is enveloped by a windy atmosphere. An understanding of the physical layout of arid lands, and the nature of processes that initiate changes therein is also fundamental to thoughtful utilization of these lands for the benefit of mankind. It is with this in mind that we prepared this book for publication. We believe that the collection of articles in this book will be useful to scientists who are interested in desert landforms and processes, and to planners of economic develop ment of arid lands. The book also serves as a guide for students as to the state of our knowledge in this field as well as to the topics that require additional research.

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.

Book Synopsis Combating Desertification and Land Degradation by : Janet Hooke
Download or read book Combating Desertification and Land Degradation written by Janet Hooke and published by Springer. This book was released on 2017-03-09 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports an approach developed to research and apply methods of assessing patterns of processes in the landscape, and suitability of different types of vegetation to mitigate soil erosion and sediment flux. Practical guidelines on a spatially strategic approach to management of land degradation at a range of spatial scales were produced. Originally developed for the Mediterranean environment, it has much wider potential global application. It provides researchers with methods to acquire the knowledge necessary for such an approach and provides practitioners with guidance on implementation and benefits of targeted methods of soil erosion control. It includes substantial information about processes and vegetation in the Mediterranean environment and the species effectiveness in soil erosion control.
Book Synopsis Desertification and Risk Analysis Using High and Medium Resolution Satellite Data by : Alberto Marini
Download or read book Desertification and Risk Analysis Using High and Medium Resolution Satellite Data written by Alberto Marini and published by Springer Science & Business Media. 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.

Book Synopsis Desertification, Land Degradation and Sustainability by : Anton Imeson
Download or read book Desertification, Land Degradation and Sustainability written by Anton Imeson and published by John Wiley & Sons. This book was released on 2012-01-24 with total page 346 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.
Book Synopsis Desertification by : Monique Mainguet
Download or read book Desertification written by Monique Mainguet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controversial, and often discussed with passion and vehemence, desertification is a problem on whose solution the survival of millions of humans is dependent. This book aims at an understanding of what is commonly called "desertification" - a term which has a connotation of irreversibility, spreading and emergence of desert-like landscapes: "land degradation" is proposed to replace it. The purpose is to present what has happened in reality, and what might be done. Illustrative worldwide analyses allow a more realistic evaluation of global land degradation. Each level of technology, excessive or insufficient, creates its own mismanagement. This is reflected in a decrease in soil productivity and eventually land degradation. The benefit to the reader is an awareness of the ecozones which have undergone the most severe land degradation, and a global overview of the phenomena, mechanisms and existing solutions.
Book Synopsis The End of Desertification? by : Roy H. Behnke
Download or read book The End of Desertification? written by Roy H. Behnke and published by Springer. This book was released on 2016-04-12 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question in the title of this book draws attention to the shortcomings of a concept that has become a political tool of global importance even as the scientific basis for its use grows weaker. The concept of desertification, it can be argued, has ceased to be analytically useful and distorts our understanding of social-environmental systems and their resiliency, particularly in poor countries with variable rainfall and persistent poverty. For better policy and governance, we need to reconsider the scientific justification for international attempts to combat desertification. Our exploration of these issues begins in the Sahel of West Africa, where a series of severe droughts at the end of the 20th century led to the global institutionalization of the idea of desertification. It now seems incontrovertible that these droughts were not caused primarily by local land use mismanagement, effectively terminating a long-standing policy and scientific debate. There is now an opportunity to treat this episode as an object lesson in the relationship between science, the formation of public opinion and international policy-making. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept. Despite an increasingly sophisticated understanding of dryland environments and societies, the uses now being made of the desertification concept in parts of Asia exhibit many of the shortcomings of earlier work done in Africa. It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. This book is an effort to critically examine that experience and accelerate the learning process in other parts of the world.

Book Synopsis Desertification: Causes, Impacts & Consequences by : Roy H. Behnke
Download or read book Desertification: Causes, Impacts & Consequences written by Roy H. Behnke and published by Springer. This book was released on 2015-11-16 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amongst the first in the new Springer-Praxis Earth System Science Series ‘Desertification: The Interplay of Science, Politics and Public Opinion’ describes how the process of desertification, a man-induced process that leads to soil nutrient depletion and reduction of biological productivity has heavily affected Sahelian droughts. The team of global experts takes our current understanding of desertification to a far broader level covering wider environmental science and public policy issues. This innovative new book attempts to distinguish between desertification hysteria and the considerable real threat that the process poses to many semi-arid landscapes and to those who inhabit them with particular focus on current scientific understandings of the mechanisms that drive desertification and reviews of the regional, continental and world-wide evidence for desertification. The book is structured into six core parts. The first part by Roy Behnke sets the scene and explains the event and related problems. The team explains how spheres and events interact and the related problems. Part 2 by Camilla Toulmin examines the evolution in thinking & ideas about desertification, the confrontation of new data & field experience with policy and legal frameworks set within the context of rising concerns about climate change. Part 3, written by Alessandra Giannini explores the scientific causes of desertification. He explores sea surface temperatures, albido and climate forecasts for the Sahel and the significant impact of climate change on desertification. Part 4 discusses regional and international implications, with David Thomas revealing the extent and causes of desertification in drylands outside the Sahel. In particular he explores desertification in the Mediterranean, sub-Saharan Africa, the former Soviet Union, China, Australia and the US, and there‘s a further section on global databases on desertification. Michael Mortimer delivers a fresh review of drought adaptation and shows how it will be conducted in order to separate the myths from reality, identifying both the scope and the limitations of adaptive capacity in managing the economic and environmental impacts of drought. In the final section of the book, Mark Stafford Smith reveals some key lessons and helps us make sense of the history of Sahelian desertification, desertification science and policy making, and how to avoid future mistakes and the challenges that lie ahead.
