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.

Available in PDF, EPUB and Kindle. Book excerpt: An expert treatise on the origin and evolution of dunes, this classic work was used by NASA in studying sand dunes on Mars and is appropriate for undergraduate and graduate students. The first book to deal exclusively with the behavior of blown sand and related land forms, its accessible style makes it an enduring reference more than half a century after its initial publication. The author studied the sands of North Africa for many years before World War II and is recognized as a leading authority on the subject. His three-part treatment begins with his wind-tunnel experiments, which he conducted to investigate the mechanism of sand transport. First, an account of the observed movement of the individual grains, followed by a chapter on the ground wind and its dependence on the type of surface over which it blows, form a comprehensive view of the interaction between wind and sand. Part Two considers small-scale surface phenomena, such as ripples and ridges, and the closely related subject of size-grading the grains. The third part uses the foregoing results to explain the growth and movement of dunes in general, and the peculiar characteristics of the two main dune types. A method of determining the internal structure of accumulated sand illuminates both the sand's carrying power for motor transport and its water-retention potential. A final chapter, derived from firsthand knowledge, examines the intriguing subject of "singing sand."

Available in PDF, EPUB and Kindle. Book excerpt: 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
