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.

This controversial book argues that the reality of the expanding desert is not so much an objective scientific fact as a political, social and observational construct. Examines the origin of the desertification myth, how it spawned multimillion dollar research initiatives and became a leading environmental issue. Uses new research findings to demonstrate that this highly vaunted problem is extremely smaller and less locally significant than previously accepted. Includes a wealth of illustrations from global examples.

Desertification and land degradation are complex phenomena, and we need to understand their causes, consequences, and means to mitigate and combat their impact. Therefore, this book aims to explain the concept and characteristics of drylands, desert and desertification, land degradation, wastelands, and the concept of ecosystem services. It also discusses various types of processes of land degradations, their characteristics, physics and indicators along with mapping, monitoring and assessment of methods involved. Concept of Ocean Biological Deserts is discussed along with international and regional efforts towards combating land degradation and desertification. Key Features: • Provides all the aspect of desertification and land degradation at one place • Includes comprehensive methods to monitor different desertification/land degradation processes • Comprehensive overview of the mapping, monitoring and modelling techniques • Role of space borne data in identifying, monitoring and combating desertification is evaluated and reported with real case studies • Explains the concept of ocean biological deserts, their characteristics and mapping

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.

Essay from the year 2014 in the subject Politics - Topic: Development Politics, grade: 1,5, University of Warwick, language: English, abstract: Drought and desertification threaten the livelihood of more than 1.2 billion people across 110 countries. Around 2 billion people live in “dry-lands”, which occupy around 40 per cent of the earth ́s land surface, while 90 per cent of the people who live in drylands are from DC (Kingsbury et al. 2012,314). Drought and desertification effect strongly the development of a country. The town Baga in Nigeria, was once a fisherman ́s village. It was at the coast of the Tschad lake, now it is more than 30km away from the lake. The increasing desertification of the region at Tschad lake drove the city to become agriculturally centred, the outcome of desertification for the local population is significant. This essay argues for a strong impact of “environmental” problems like desertification and deforestation on the development of a country. This essay wants to highlight the importance of these problems for development science. The key argument of this essay is the reciprocal influence between development and environmental problems. Development often generates environmental problems, which in turn aggravates future development.

Lands lost to desert may effectively be lost for ever, so desertification is humanity's most obvious despoliation to the planet. It is certainly one of the most serious environmental problems facing the world today. In this book the author describes what is happening and where. Although the problem is greatest in developing countries, it is by no means confined to them. Australia, Africa, the USA and India are all affected. In the 1970s an international Plan of Action was drawn up to bring the phenomenon under control, but it was never implemented. Now that the situation is more serious than ever before, this book urges new action and describes many of the myriad ways in which it is possible to arrest the progress of desertification. It describes, too, not just the failures, but the considerable successes that have been achieved. Originally published in 1990

Desertification has re-emerged as a topic of global significance as a consequence of the United Nations Conference on Environment and Development. When first addressed over a generation ago, attention was drawn to the compelling, spectacular images of sand dunes engulfing farmlands and parched cattle dying around wells. Research tended to focus on these events as unusual phenomena that involved the unfortunate collision of climate and `irrational' land use. Since then, the work of many researchers has shown us that desertification is a multifaceted problem that involves climatic, biogeochemical, political, and socio-economic processes that operate more or less continuously but at rates that vary in time and space. No attempts to arrest or reverse desertification that ignore this complexity are likely to succeed. In a single volume, `Desertification in Developed Countries' describes the multiple dimensions of desertification as well as the novel approaches that have been used to address it within the economies of developed countries. This is done from the perspectives and experiences of the numerous authors who have contributed to this book.

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.
