Book Description
The twelve contributions in this volume represent the results of a ten year interdisciplinary workshop on "desert margins" - concerned with the geomorphological, geochemica, mineralogical, sedimentological, soil scientific characterisation of (semi-) deserts in Spain, Africa, Arabia and China. Desert sediments and soils as well as processes and characteristics of their formation are regarded from different geoscientific perspectives. The subjects of research include the development of desert soils and landscapes, the formation of (alluvial) loess, swamp ores, fulgurites and floodout sediments and focus on the reconstruction of palaeoecological events and changes. A critical study of dating methods rounds off the book.

Book Description
The environmental setting within the Central Sahara was subject to considerable changes during Late Quaternary, mainly driven by major global climate variations, although human impact increased constantly since Early Holocene.Such global events can be reconstructed with the help of reliefs, sediments and palaeosoils and their specific morphological

Book Description
The Sahara-Sahel borderland occupies a critical geographical position due to its recurrent latitudinal shifts, continually having a strong impact on humans, animals and plants. Gobero is located at the southern limits of the present Sahara, in Niger. The archaeological record at this site encompasses the re-occupation of the Sahara ca 10,000 years ago until approximately 2000 years ago. During this long period, Gobero witnessed significant fluctuations in climate and water resource availability that resulted in cycles of human occupation, abandonment and re-occupation around a natural basin occupied by a palaeolake, until desertification became an irreversible process and the area turned into a no-return frontier for its occupants. This book presents the archaeological, anthropological and environmental data collected during the 2005 and 2006 field seasons at Gobero. Various factors highlight the extraordinary significance of this site. Thanks to its geographical position, straddling the ancient shifting border(s) of the Sahara and the Sahel, the Gobero's archaeological record reveals critical population movements in this part of Africa and different economic and technological strategies its inhabitants employed to adapt to changing environmental conditions. The presence of both settlement and burial features at Gobero gives a comprehensive view of the cultural, social, economic and funerary traditions of the people who lived and died at this site during almost the entire Holocene. The results from these archaeological investigations provide a term of reference for future research and interpretations of past human occupations in the Sahara, as well as North and West Africa.

Book Description
Availability of water and desiccation of important water reservoirs is a vital challenge in semi-arid to arid climates with growing economy and population. Low quantities of precipitation and high evaporation rates leave the water supply vulnerable to human activity and climatic variations. Endorheic basins of Northern Iran were hydrologically landlocked within geological timescales and thus bear evidence of past variations of water resources in generations of water related landforms, like abandoned lake level shorelines, alluvial fans and stream terraces. Understanding the development of these landforms reveals crucial information about past water reservoirs and landscape history. This study offers a comprehensive approach on understanding the geomorphological development of the landscape throughout Late Pleistocene and Holocene times. It integrates remote sensing and geographic information system analysis, with geomorphological and stratigraphical mapping fieldwork and detailed sedimentological investigations. The work shows the importance of analytical geomorphological mapping for delineating stratigraphic units of the Iranian Quaternary. Thus, several phases of drying and lake level retreat were identified in parallel geoarchives and could be dated to a time span from today to Late Pleistocene. The findings link the fate of the citizens of the ancient city of "Tepe Hissar" to their access to water and to the power of geomorphological processes, which started changing their environment.

Book Description
The Nile Basin contains a record of human activities spanning the last million years. However, the interactions between prehistoric humans and environmental changes in this area are complex and often poorly understood. This comprehensive book explains in clear, non-technical terms how prehistoric environments can be reconstructed, with examples drawn from every part of the Nile Basin. Adopting a source-to-sink approach, the book integrates events in the Nile headwaters with the record from marine sediment cores in the Nile Delta and offshore. It provides a detailed record of past environmental changes throughout the Nile Basin and concludes with a review of the causes and consequences of plant and animal domestication in this region and of the various prehistoric migrations out of Africa into Eurasia and beyond. A comprehensive overview, this book is ideal for researchers in geomorphology, climatology and archaeology.

Book Description
Many dryland regions contain archaeological remains which suggest that there must have been intensive phases of settlement in what now seem to be dry and degraded environments. This book discusses successes and failures of past land use and settlement in drylands, and contributes to wider debates about desertification and the sustainability of dryland settlement.

Book Description
Ecohydrology emerges as a new field of research aiming at furthering our understanding of the earth system through the study of the interactions between the water cycle and vegetation. By combining the analysis of biotic and abiotic components of terrestrial ecosystems, this volume provides a synthesis of material on arid and semiarid landscapes, which is currently spread in a number of books and journal articles. The focus on water-limited ecosystems is motivated by their high sensitivity to daily, seasonal, and decadal perturbations in water availability, and by the ecologic, climatic, and economic significance of most of the drylands around the world. Conceived as a tool for scientists working in the area of the earth and environmental sciences, this book presents the basic principles of eco-hydrology as well as a broad spectrum of topics and advances in this research field. The chapters collected in this book have been contributed by authors with different expertise, who work in several arid areas around the World. They describe the various interactions among the biological and physical dynamics in dryland ecosystems, starting from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns.
