Book Description
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.

Book Description
Combining the expertise of an archaeologist and a geologist, this important study gives a balanced evaluation of South African climatic history, summarizing such diverse evidence as dune systems, stable isotopes, pollen, fossil bones, and the distribution of Stone Age people. Together, these factors show the effects of climatic changes on terrestrial ecosystems in the southern African landscape. A comprehensive overview of the nature, scale, and timing of changes coincident with the worldwide interglacial-glacial-interglacial cycle is also presented. The potentials and pitfalls of palaeonenvironmental reconstructions and the implications for biogeography, human population distributions, and palaeoclimatic models are also featured. Researchers in these areas will appreciate this unique and insightful exploration into the climatic history of this fascinating region.

Book Description
West Africa and the eastern Atlantic stretching from Mauritania in the north to Namibia in the south offer a large latitudinal stretch incorporating nearly symmetrical climatic gradients from the Equator. On the time scale of Quaternary Glacial and Interglacial cycles, today, we possess well-documented and recently published marine sedimentary records showing changes in oceanic and atmospheric circulations and terrestrial fluxes. Deep-sea sediment records contain a wide range of palaeoenvironmental indicators like oxygen and carbon isotopes, alkenones, foraminiferal and other planktonic assemblages over time periods up to and greater than 125,000 years. These are signals of temperature and circulation shifts and allow Interglacial and Glacial comparisons on a regional and inter-hemispheric scale. However, this effort to synthesize the existing knowledge cannot yet aspire to a global modelling. Linking with terrestrial records, albeit spatially patchy and generally lacking a firm chronology, this book points to shorter time scale chronologies from lakes, marshes and river deposits. Diverse and not very wellknown literature, both French and English, is reported here. Lastly, the book records recent knowledge of the first steps of human occupation of frequently hostile environments and considers the environmental impact of ancient and modern societies.* Covers the recent studies about marine Quaternary environments off West Africa, as well as continental Quaternary environments of tropical and sub-tropical West Africa (over 10,000 to 100,000 years)* Compares the parallel between palae-oenvironmental trends according to latitudinal gradients

Book Description
During the Neogene - covering the last 23 Million years - the evolution of the environmental setting in Africa was subject to considerable changes. Natural shifts, slow and rapid, evidenced by modifications in palaeogeography, geodynamics, climate, and vegetation have caused repeated and strong changes of ecosystems in the lower latitudes. Using a variety of proxy data - researched and applied by many authors from numerous disciplines - an attempt is made to reconstruct African landscapes over space and time. Besides such spatio-temporal oscillations in recently humid, semi-humid, and dry areas of Africa, this volume of Palaeoecology of Africa (PoA) focuses on long term interrelationships between ecosystem dynamics and climate change, not ignoring the ever growing and ongoing influence of humans on natural ecosystems since the Quaternary. Regionally, this volume lays a strong focus on Nigeria (Niger Delta). Facing the omnipresent challenges of Global Change, an increasing number of African scientists is involved in palaeoenvironmental and palaeoclimatic research, both theoretical and applied. PoA systematically supports established as well as junior African scientists in the field of sustainable cooperation and academic capacity building. This book will be of interest to all concerned with or interested in up-to-date research on Neogene to Quaternary low latitudes ecosystem changes and their respective interpretation in the framework of natural climate and vegetation change evidenced by a variety of methods that allow to read and learn from the past by following the motto, "The geologic foretime as the key to the present, and possibly to the future." Palynologists, Geologists, Geographers, Archaeologists, and Geomorphologists will find this edition equally useful for their work.
