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....

Early MIS 3 occupation of Mochena Borago Rockshelter, Southwest Ethiopian Highlands: Implications for Late Pleistocene archaeology, paleoenvironments and modern human dispersals doi Spatial

Between 70 and 50 ka BP, anatomically modern humans dispersed across and out of Africa to eventually populate all inhabitable continents. Knowledge of paleoenvironments and human behavioral patterns in Africa prior to and during these dispersals is crucial for understanding how and why hunter-gatherers were able to adapt rapidly to the new environments they encountered. However, few well-dated sites from this time period are known from the Horn of Africa, one of the purported staging areas for population...

L’impact environnemental sur la formation des assemblages lithiques unifaciaux et bifaciaux « micoquiens » ou« MMO » d’Europe central. Transitions, ruptures et continuité en Préhistoire.

Research of the last two decades has considerably changed our notion of the cultural units connected with the late Middle Palaeolithic of Europe. The revision of lithic assemblages from Middle Palaeolithic sites in Germany resulted in a new understanding of the relationship between techno-typological entities of artefact assemblages, on the one hand, and the utilization of prehistoric natural landscape, on the other hand.

Jungpleistozäne Küstenveränderungen am Roten Meer und die Ausbreitung des Modernen Menschen (B.Sc. thesis University of Cologne) Spatial

This Bachelor of Science thesis will show the changes of the coastal area of the Red Sea at the time of the Upper Pleistocene and their effects on the dispersal of anatomically modern humans (AMH). Thus insights about possible routes of migration of AMH out of Africa shall be gained. For this research the palaeoclimate, the sea level changes and the tectonic processes will be decribed. By reconstruction of coastal areas it will be shown that a trespassing of the Bab al-Mandab strait at the mouth of the Red...

The Palaeolithic site Sima de Las Palomas de Teba, Southerrn Spain – Site formation processes and chronostratigraphy Spatial

Abstract (The Palaeolithic site Sima de las Palomas de Teba, Southern Spain Site formation processes and chronostratigraphy: The rockshelter sequence consists of 6 m thick stonerich silty clay loam including several archaeological levels with artefacts of Mousterian affinity, bone and charcoal. Stratigraphy and site formation processes were characterised by sedimentological, geochemical and micromorphological investigations. Sediments were dated using IRSL and OSL and the time of the last heating of burnt...

Black Carbon: fire fingerprints in Pleistocene loess-palaeosol archives in Germany doi Spatial

Past environmental changes were frequently accompanied by changes in fire regimes. However, the extent to which the residue of ancient fires (black carbon, BC) is abundant in Pleistocene palaeosols remains largely unknown, and whether, and to which degree its occurrence and composition relates to pedogenetic processes and palaeoenvironmental change. We studied three Pleistocene loesspalaeosol sequences from western Germany for systematic variation in BC quantity and quality during Marine Isotope Stages 5e...
