Late Quaternary Environmental Change addresses the interaction between human agency and other environmental factors in the landscapes, particularly of the temperate zone. Taking an ecological approach, the authors cover the last 20,000 years during which the climate has shifted from arctic severity to the conditions of the present interglacial environment.

Holywell Coombe, an embayment in the chalk scarp overlooking Folkestone, Kent, was designated a geological Site of Special Scientific Interest in 1985 because it contains richly fossiliferous Late Quaternary sediments providing a unique archive of the last 13,000 years. The construction of the Channel Tunnel across the Holywell Coombe SSSI brought about a major rescue excavation, funded by Eurotunnel, that set an important precedent in Earth Science conservation. This multidisciplinary investigation has added enormously to our understanding of the environment and natural history of the Late-glacial and Holocene. The climatic complexity of the Late-glacial is recorded in the nature of the sediments, the fossils recovered from them and the soils developed within them. From the Neolithic, and especially during the Early Bronze Age, the slopes were destabilized as a result of forest clearance, leading to the accumulation of hillwash. Archaeological excavations in the hillwash have revealed evidence of prehistoric occupation and agricultural activity in the coombe. Eurotunnel also funded biological surveys of the local terrestrial and aquatic habitats. Combining these with the fossil evidence, it has been possible to document the pedigree of our present fauna and flora, providing one of the most detailed and comprehensive studies of its kind. With contributions from eminent Quaternary scientists from several countries, this work will be an important resource for researchers, lecturers and postgraduate students in Quaternary sciences - geology, geography, biology, ecology and archaeology - as well as for government bodies concerned with nature conservation and environmental protection.

The global climate changes that led to the expansion and contraction of high latitude ice sheets during the Quaternary period were associated with equally dramatic changes in tropical environments. These included shifts in vegetation zones, changes in the hydrology and ecology of lakes and rivers, and fluctuations in the size of mountain glaciers and sandy deserts. Until recently it was thought that such changes were triggered by fluctuations in the distribution of polar ice cover. Now there is increasing recognition that the tropics themselves have acted as drivers of global climate change over a range of timescales. The aim of Quaternary Environmental Change in the Tropics is to provide a synthesis of the changes that occurred in tropical terrestrial and marine systems during the Pleistocene and Holocene, complementing data-derived reconstructions with output from state-of-the-art climate models. It is targeted at final-year undergraduate students and research specialists, but will provide an introduction to tropical Quaternary research for a variety of other readers.

Due to political pressures, prior to the 1990s little was known about the nature of human foraging adaptations in the deserts, grasslands, and mountains of north western China during the last glacial period. Even less was known about the transition to agriculture that followed. Now open to foreign visitation, there is now an increasing understanding of the foraging strategies which led both to the development of millet agriculture and to the utilization of the extreme environments of the Tibetan Plateau. This text explores the transition from the foraging societies of the Late Paleolithic to the emergence of settled farming societies and the emergent pastoralism of the middle Neolithic striving to help answer the diverse and numerous questions of this critical transitional period. * Examines the transition from foraging societies of the Late Paleolithic to the emergence of settled farming societies and the emergent pastoralism of the middle Neolithic * Explores explanatory models for the links between climate change and cultural change that may have influenced the development of millet agriculture * Reviews the relationship between climate change and population expansions and contraditions during the late Quaternary

The South Atlantic plays a significant role as a link between the Antarctic Ocean and the North Atlantic, both in terms of the heat budget of the North Atlantic and the circulation of the entire ocean. The heat and mass exchanges between the Antarctic Ocean and the South Atlantic during the Late Quaternary have been investigated over the past ten years, including their impact on world climate. This has required the study of present-day early diagenetic processes in the water column and sediments, as well as sediment properties that have a close relationship to environmental parameters ("proxies"), which can be used to decipher past conditions (temperature, salinity, productivity, etc.). The interdisciplinary research project "The South Atlantic in the Late Quaternary - Reconstruction of material budgets and current systems" was a long-term scientific program at Bremen University. This program benefited from the sample material gained on several expeditions with the research vessels Meteor and Polarstern. This book presents the summarized results of the various topics of study in 30 articles arranged in seven sections.

Ice Age Earth provides the first detailed review of global environmental change in the Late Quaternary. Significant geological and climatic events are analysed within a review of glacial and periglacial history. The melting history of the last ice sheets reveals that complex, dynamic and catastrophic change occurred, change which affected the circulation of the atmosphere and oceans and the stability of the Earth's crust.

Founded in 1966, the internationally recognized and acclaimed Series ‘Palaeoecology of Africa’ publishes interdisciplinary scientific papers on landscape evolution and on former environments of the African continent. Beginning with topics such as changes in climate and vegetation cover, the papers expand horizons and interconnections to various types of environmental dynamics from the Cainozoic up to the present; moreover, the aspect of human influence since the Late Quaternary is related to many of the areas studied. Volume 31 presents four comprehensive papers on long- and short-term processes of landscape evolution (geological history, neotectonics and proxy Quaternary alluvia), as well as a recent regional perspective on environmental problems in Southern Cameroon. The book acts as a showcase for successful North-South cooperation and capacity building for empowering African Universities. It is problem oriented and applied, and illustrates how scientific and interdisciplinary cooperation can work. In the framework of the German Research Foundation’s (DFG, Deutsche Forschungsgemeinschaft) funded "Rain Forest Savanna Contact" project (2003-2009) two abbreviated English versions of PhD theses are here published, one by J. Eisenberg on neotectonics and the other by M. Sangen on river sediments in rain forest-savanna transitional zones. Complementary articles are an introduction on geological history, by B. Kankeu et al. and a paper on environmental risks by M. Tchindjang et al., together these complete the results of this joint German-Cameroonian research project. This book will be of interest to all concerned with ecosystems dynamics, tropical forests, savannas and related development problems of Third World countries, especially regional planners, ecologists, botanists, earth scientists and students of the Quaternary (e.g. LGM and Holocene ecosystem dynamics, Global Change). It will be valuable for advanced undergraduates and postgraduates as a reference for new research articles on the topic of long‐term geologic‐tectonic and Quaternary landscape evolution in an up‐to‐now not well explored marginal area of the Western Congo basin.
