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.

After UNCED (United Conference on Environment and Development, Rio de Janeiro, July 1992), a second edition of Desertification was necessary. About 150 corrections, amendments and additions take scientific progress into account. The author also presents an updated chapter in which the results of UNCED are analyzed. This book aims at an understanding of what is commonly called "desertification" - a term which is proposed to be replaced by "land degradation". Each level of technology, excessive or insufficient, creates its own mismanagement. This is reflected in an increase in land degradation and eventually a decrease in soil productivity. The benefit to the reader is an awareness of the ecozones and a global overview of the phenomena, mechanisms and existing solutions.

The United Nations Water Conference (in Argentina in March 1977) and the United Nations Conference to Combat Desertification (in Kenya in August 1977) reflect the worldwide attention that recent global food shortages and growing populations have drawn to the destruction of arable and potentially arable land. This collection of articles focuses on a primary form of such destruction: desertification—the creation of desert-like conditions in arid or semiarid regions either by changes in climate patterns or by human mismanagement, or both. The contributors—representing a range of disciplines—examine and evaluate the social, political, economic, environmental, and technical problems related to the causes and effects of desertification.

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

This is the first comprehensive survey of all the deserts of Arabia, based largely on the author’s 50 years of experience there. The text deals with every kind of desert in the region, from vast sand seas to clay pans and stony plains to volcanic flows. Along with dune types unique to the region the author outlines climatic changes, current ecology and human influence on desertification.

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.

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
