This book presents the natural, environmental and scenic richness of the world’s coastal and marine areas classified by UNESCO as “Natural World Heritage Sites”. Representing well-preserved areas of exceptional significance to the planet and to humankind, they include a total of 49 marine sites, formed by reefs, atolls and gulfs, and 35 coastal sites in all oceans and all continents with exception of Antarctica. They are being protected and preserved from most degrading uses for future generations as an important legacy from the past. Exploring their richness, this book analyzes and explains these sites in a clear, understandable, scientific way, and is of interest to all who work in or care about the geosciences, environmental sciences and biosciences.

Early descriptions and considerations of the characteristics of modern eolian sand deposits, mostly in the great sand seas of the world, date back to the 1880's and 1890's, when pioneer geologists and explorers wrote their classic papers on desert dunes. One or two decades later, interest in eolian processes greatly increased when wind-formed deposits were recognized in ancient sandstones in many parts of the world and in rocks of many ages. Throughout the 20th century, as the science of geology has expanded and the programs of the U.S. Geological Survey have proliferated to keep pace, dune studies have had a similar growth. Work was initially concentrated mostly on the description of dune forms or morphology and on analysis of textural features; by midcentury, however, major contributions had been made to the physics of eolian sand by detailed studies and interpretations of minor eolian structures, by statistical analyses of cross-strata dip directions, and by the development of systems for dune classification. Most recently, interest has been renewed in detailed grain studies, in the study of cross-strata, and in interpretation of dune patterns by means of aerial photographs and Landsat imagery. A major feature of this report on global sand seas is the compilation and comparison of available data based on many different methods of investigation. The application of these studies to economic problems, which is described in one chapter, clearly illustrates the importance of eolian deposits to our present culture and to human welfare. H.

This unique richly-illustrated account of the landforms and geology of the world’s coasts, presented in a country-by-country (state-by-state) sequence, assembles a vast amount of data and images of an endangered and increasingly populated and developed landform. An international panel of 138 coastal experts provides information on “what is where” on each sector of coast, together with explanations of the landforms, their evolution and the changes taking place on them. As well as providing details on the coastal features of each country (state or county) the compendium can be used to determine the extent of particular features along the world’s coasts and to investigate comparisons and contrasts between various world regions. With more than 1440 color illustrations and photos, it is particularly useful as a source of information prior to researching or just visiting a sector of coast. References are provided to the current literature on coastal evolution and coastline changes.

A revised introduction to aeolian geomorphology written by noted experts in the field The new, revised and updated edition of Aeolian Geomorphology offers a concise and highly accessible introduction to the subject. The text covers the topics of deserts and coastlines, as well as periglacial and planetary landforms. The authors review the range of aeolian characteristics that include soil erosion and its consequences, continental scale dust storms, sand dunes and loess. Aeolian Geomorphology explores the importance of aeolian processes in the past, and the application of knowledge about aeolian geomorphology in environmental management. The new edition includes contributions from eighteen experts from four continents. All the chapters demonstrate huge advances in observation, measurement and mathematical modelling. For example, the chapter on sand seas shows the impact of greatly enhanced and accessible remote sensing and the chapter on active dunes clearly demonstrates the impact of improvements in field techniques. Other examples reveal the power of greatly improved laboratory techniques. This important text: Offers a comprehensive review of aeolian geomorphology Contains contributions from an international panel of eighteen experts in the field Includes the results of the most recent research on the topic Filled with illustrative examples that demonstrate the advances in laboratory approaches Written for students and professionals in the field, Aeolian Geomorphology provides a comprehensive introduction to the topic in twelve new chapters with contributions from noted experts in the field.

Physical landscapes are one of the most fascinating facets of our Planet, which tell stories about the evolution of the surface of the Earth. This book provides up-to-date information about the geomorphology of the selected ‘classic’ sites from around the world and shows the variety of geomorphological landscapes as moulded by different sets of processes acting over different timescales, from millions of years to days. The volume is written by nearly fifty geomorphologists from more than twenty countries who for many years have researched some of the unique sceneries on the planet. The thirty six chapters present each continent of the world. They describe landscapes of different origin, so that the reader can learn about the complexity of processes behind the sceneries. This is a useful reference book, linking geomorphology with global initiatives focused on nature conservation.

With his penchant for nature, science, writing and photography, the desert ecologist, Dr Joh R Henschel, could not help but document the conversations about the natural world with his friend Zophosis Moralesi, a Toktokkie as beetly as can be. The Toktok Talkie articles were first published as weekly newspaper columns between 2011 and 2013, and these are now collated in this book. In it, Joh reveals some of his musings about nature and his observations of peoples' relationships to it. He deftly interweaves the human defiance of nature, symbolised by the Ancient Mariner, with nature's many values and ultimate power of having the last word, presented by a humble messenger, the Toktokkie beetle, Zophosis moralesi. His first experience of the Namib in 1977 became love at first sight. Since then he has been conducting research in the Namib and several deserts world-wide, reported in numerous scientific papers and technical documents. After spending over three decades in Namibia, Joh and his wife, Theresa, moved to Kimberley in South Africa in 2013, where he joined the National Research Foundation to continue arid land research through the South African Environmental Observation Network (SAEON).

This open access book richly illustrates the first, and comprehensive, account of the country’s biomes and ecoregions, the driving forces that account for their diversity and vulnerability, and the ecological principles that provide an understanding of the patterns and processes that have shaped landscapes, ecoregions, and ecosystems. Angola encompasses the greatest diversity of terrestrial biomes and is the second richest in terms of ecoregions, of any African country. Yet its biodiversity and the structure and functioning of its ecosystems are largely undocumented. The author draws on personal field observations from over 50 years of involvement in ecological and conservation studies in Angola and across Southern Africa. The vast recent literature published by researchers in neighboring, better resourced countries provides depth to the accounts of ecological principles and processes relevant to Angola and thus contributing to the understanding and sustainable management of its natural resources.
