“…2). Paleolakes Chalbi (Nyamweru 1989), Chew Bahir (Foerster et al 2012;Golubtsov and Habteselassie 2010;Grove et al 1975;Umer et al 2004), and Suguta (Garcin et al 2009;Garcin et al 2012;Junginger et al 2014) show concurrent desiccation, reflecting a change in local climate and a reduction in Omo River inflows. Later transgression phases inferred for Lake Turkana may have been part of a regional pluvial phase based on recharge of smaller water bodies in the southern Ethiopian Plateau (Lamb et al 2000;Umer et al 2004) and the northern Kenyan Highlands (Barker et al 2001;Butzer et al 1972;Hamilton 1982;Olago et al 2000).…”

Throughout the Holocene, Lake Turkana has been subject to drastic changes in lake levels and the subsistence strategies people employ to survive in this hot and arid region. In this paper, we reconstruct the position of the lake during the Holocene within a paleoclimatic context. Atmospheric forcing mechanisms are discussed in order to contextualize the broader landscape changes occurring in eastern Africa over the last 12,000 years. The Holocene is divided into five primary phases according to changes in the strand-plain evolution, paleoclimate, and human subsistence strategies practiced within the basin. Early Holocene fishing settlements occurred adjacent to high and relatively stable lake levels. A period of high-magnitude oscillations in lake levels Afr Archaeol Rev (2015) ensued after 9,000 years BP and human settlements appear to have been located close to the margins of the lake. Aridification and a final regression in lake levels ensued after 5,000 years BP and human communities were generalized pastoralists-fishers-foragers. During the Late Holocene, lake levels may have dropped below their present position and subsistence strategies appear to have been flexible and occasionally specialized on animal pastoralism. Modern missionary and government outposts have encouraged the construction of permanent settlements in the region, which are heavily dependent on outside resources for their survival. Changes in the physical and cultural environments of the Lake Turkana region have been closely correlated, and understanding the relationship between the two variables remains a vital component of archaeological research.Résumé Tout l'Holocène, le lac Turkana a été soumis à des changements drastiques dans l'altitude des lacs et les stratégies de subsistance des gens utilisent pour survivre dans cette région chaude et aride. Dans cet article, nous reconstruisons la position du lac au cours de l'Holocène dans un contexte paléoclimatique. Mécanismes de forçage atmosphériques sont discutées afin de contextualiser les changements de paysage plus larges qui se produisent en Afrique orientale au cours des 12.000 dernières années. L'Holocène est divisé en cinq phases principales en fonction des changements dans l'évolution altitude du lac, paléoclimats et les stratégies de subsistance humains pratiqués dans le bassin. Premiers établissements de pêche de l'Holocène ont eu lieu à proximité d'altitude d'eau élevés et relativement stables. Une période d'oscillations de grande amplitude dans l'altitude du lac s'ensuit après 9000 années BP et les établissements humains semblent avoir été situé à proximité des marges sur le lac. Aridification et une régression finale du altitude des lacs s'ensuit après 5000 années BP et les communautés humaines sont généralisées éleveurs-pêcheurs-cueilleurs. Au cours de l'Holocène tardif, les altitudes des lacs pourraient avoir chuté en dessous de leur position actuelle et les stratégies de subsistance semblent avoir fait preuve de souplesse et de temps en temps spécialisé sur le pas...

“…A spike in terrigenous dust from collected offshore from the western Sahara ( Figure 3G; deMenocal et al, 2000;Adkins et al, 2006), abrupt reductions in the distribution of Guineo-Congolian plant taxa after 4500 years BP north of 20 • N (Hély et al, 2014) and lake level reconstructions from Lake Mega-Chad (Armitage et al, 2015) and Ethiopia (Gillespie et al, 1983;Gasse and Van Campo, 1994;Gasse, 2000) infer abrupt hydrological regime shifts to dry conditions (see also Tierney and deMenocal, 2013). Curiously, potassium content of sediments from the now-dry Lake Chew Bahir, located in southern Ethiopia indicates a slow, but steady transition to a xeric landscape in phase with orbital precession (Foerster et al, 2012), which is in contrast to nearby hydrological proxies in northern Kenya that show rapid changes in the hydrological cycle that culminated in an 80 m regression in the level of Lake Turkana at 4500 years BP (Garcin et al, 2009(Garcin et al, , 2012Junginger et al, 2014;Bloszies et al, 2015). Such discordance in proxy data, even at scales of hundreds of kilometers, is typical for the terminal AHP.…”

Garcin et al [50] suggested high paleolake levels for Lake Suguta for the periods 16,500 to 15,000 y BP, a high stand at 12,800 y BP and a high lake level from 11,800 y BP to 8500 y BP.

The Delineation of Paleo-Shorelines in the Lake Manyara Basin Using TerraSAR-X Data

Abstract:The purpose of this paper is to describe the delineation of paleo-shorelines using high resolution microwave images and digital image processing tools, and with that to contribute to the understanding of the complex landscape evolution of the Lake Manyara Basin. The surroundings of Lake Manyara are the focus of several paleo-archeological investigations, since the location is close to Olduvai Gorge, where paleo-anthropological findings can be traced back to homo habilis. In the catchment of Lake Manyara two hominin-bearing sites (0.78 to 0.63 Ma), lots of vertebrate fossils and hand axes from different periods were found. Understanding the development and extent of the lake is crucial for understanding the regional paleo-environment of the Quaternary. Morphological structures of shorelines and terraces east of Lake Manyara were identified from TerraSAR-X StripMap images. By applying a Canny edge detector, linear features were extracted and revised for different image acquisitions using a contextual approach. Those features match literature and field references. A digital elevation model of the region was used to map the most distinct paleo-shorelines according to their elevation.
