Climate-Driven Ecosystem Succession in the Sahara: The Past 6000 Years doi Spatial

Desiccation of the Sahara since the middle Holocene has eradicated all but a few natural archives recording its transition from a “green Sahara” to the present hyperarid desert. Our continuous 6000-year paleoenvironmental reconstruction from northern Chad shows progressive drying of the regional terrestrial ecosystem in response to weakening insolation forcing of the African monsoon and abrupt hydrological change in the local aquatic ecosystem controlled by site-specific thresholds. Strong reductions...

Les techno-complexes Ibéromaurusiens d’Ifri El Baroud (Rif Oriental, Maroc)

This report summarizes the results of excavations conducted by the Institut National des Sciences de l’Archéologie et du Patrimoine and the German Archaeological Institute at Ifri el-Baroud (Gunpowder Cave). The cultural deposits of Ifri el-Baroud showed to be of a depth of up to 3 meters and to have formed between the 19th and 8th century BC, as proved by a series of radiocarbon datings. The upper part of the stratigraphy consists of an “escargotière” from terrestrian snails, the lower part is formed by a...

The Epipalaeolithic–Neolithic transition in the Eastern Rif Mountains and the Lower Moulouya valley, Morocco Spatial

The Neolithic transition, since decades in a particular focus of the Western Mediterranean archaeological research, recently receives new input concerning the chronological frame (Carvalho 2010), the development of regional groups (Manen et al. 2010) or raw material supply (Binder et al. 2010). One of the most interesting topics about this is the variability of the archaeological record in the Southern Iberian Peninsula. This seems to be closely linked to the complexity of the environment and the...

Temporal and spatial corridors of Homo sapiens sapiens population dynamics during the Late Pleistocene and early Holocene doi

“Our Way to Europe – Culture-Environment Interaction and Human Mobility in the Late Quaternary” is a research initiative that is funded since July 2009 by the German Research Foundation (DFG) as a Collaborative Research Centre (CRC). The CRC 806 is based at the University of Cologne, University of Bonn and the RWTH Aachen University. The present special issue of Quaternary International compiles 17 contributions defining the starting points and describing first results of the CRC 806. All contributions...

Looking around Peştera Cu Oase: The beginnings of Upper Paleolithic in Romania Spatial

In contrast to the widely acknowledged anthropological finds in Oase Cave and to the key geographical position of Romanian territory for the assumed dispersion of Anatomically Modern Humans in Europe, the archaeological information regarding the emergence of the Upper Paleolithic in Romania remains poorly known to a broader scientific community. The prolonged theoretical and methodological isolation of the Romanian Paleolithic research has particularly contributed to keeping the regional archaeology out...

Climatic change recorded in the sediments of the Chew Bahir basin, southern Ethiopia, during the last 45,000 years Spatial

East African paleoenvironments are highly variable, marked by extreme fluctuations in moisture availability, which has far-reaching implications for the origin, evolution and dispersal of Homo sapiens in and beyond the region. This paper presents results from a pilot core from the Chew Bahir basin in southern Ethiopia that records the climatic history of the past 45 ka, with emphasis on the African Humid Period (AHP, w15e5 ka calBP). Geochemical, physical and biological indicators show that Chew Bahir...

Top down: New satellite data and ground-truth data as base for a reconstruction of ancient caravan routes. Examples from the Western Desert of Egypt Spatial

Thanks to new satellite data, it is possible to examine deserts area-wide for linear structures. Additionally, digital elevation models can be use to evaluate the geomorphological situation. In conjunction with historical sources and ground-truth data, these data allow us, for the first time, to reconstruct the position of the caravan routes with reasonable accuracy, here exemplified for the extremely arid Western Desert of Egypt. On the central Egyyptian Limestone Plateau where stony ground (hamada, serir)...

Perched groundwater at the northwestern coast of Egypt: a case study of the Fuka Basin doi Spatial

Perched groundwater resources on the northwestern coast of Egypt have thus far been little studied. However, if replenished by rainwater, they can provide a considerable amount of renewable water, i.e., for sustainable irrigation. These resources are limited, show different salinity contents and are endangered by overuse, pollution and by the sea level rising in the context of global warming. This paper presents new climatic data, geomorphologic, geologic, geochemical and hydrological researches in...

Kultur- und Landschaftswandel im ariden Afrika (Exkurs O. Bubenzer: Wüstenränder - sensitive ökologische, ökonomische und soziale Räume) Spatial

In vielen Trockengebieten der Erde haben der Klimawandel, ein überdurchschnittlich hoher Bevölkerungsdruck und eine zunehmende Ressourcen-, Nahrungsmittel- und Energienachfrage zu Landnutzungsänderungen, Migration, Ausweitung von Bewässerungsflächen oder zunehmender Verstädterung und damit einhergehenden Prozessen der Bodendegradation oder gar Desertifikation sowie zu physischem oder ökonomischem Wassermangel geführt. Während in prähistorischer Zeit das menschliche Handeln von den naturräumlichen...

Ages for the Middle Stone Age of Southern Africa: Implications for Human Behavior and Dispersal Spatial

The expansion of modern human populations in Africa 80,000 to 60,000 years ago and their initial exodus out of Africa have been tentatively linked to two phases of technological and behavioral innovation within the Middle Stone Age of southern Africa—the Still Bay and Howieson’s Poort industries—that are associated with early evidence for symbols and personal ornaments. Establishing the correct sequence of events, however, has been hampered by inadequate chronologies. We report ages for nine sites from...

Towards a Reconstruction of Land Use Potential - Case Studies from the Western Desert of Egypt doi Spatial

This chapter is situated in the field among archaeology, geomorphology, and ecology. Two case studies from different east-Saharan landscape units classify and analyse archaeological, geoscientific, and remote-sensing data of Early and Mid-Holocene archaeological sites. The section combines the approaches of landscape ecology and landscape archaeology. The aim is a parameterisation of the research areas with respect to structural and ecological features. The data were used within a Geographical...

Geoarchaeological site documentation and analysis of 3D data derived by terrestrial laser scanning doi

Terrestrial laser scanning was conducted to document and analyse sites of geoarchaeological interest in Jordan, Egypt and Spain. In those cases, the terrestrial laser scanner LMS-Z420i from Riegl was used in combination with an accurate RTK-GPS for georeferencing of the point clouds. Additionally, local surveying networks were integrated by established transformations and used for indirect registration purposes. All data were integrated in a workflow that involves different software and according results....
