The itinerary included oases and lakes north west of the Mourdi Depression: a.m. 4 Jan 2009 the Demi Oasis, and in the afternoon and evening the uninhabited Teguedei Oasis and Saline followed by Lake Boko. Lake Boko was again visited early on 6 Jan followed by the south shore of Lake Ounianga Serir Osaia, at midday Lake Katam and in the afternoon the Ounianga Kebir Oasis and the east shore of Lake Ou­ nianga Kebir (Lake Yoa). Early on 6 Jan the expedition visited a small lake east of the Ounianga Kebir Oasis and later a stretch of shore on the southern edge of Lake Yoa. On 5 and 6 Jan 2009 some 525 Marbled Teal were observed on three of the lakes - a surprisingly high number but nonetheless a minimum figure. Due to the short and random observation stops, and as not all lakes in the complex were visited, a number of Marbled Teal probably remained undetected. Nonetheless, the numbers quoted qua­ lifies the Ounianga Lake complex (from N 19°037E 20°29’ to N 18°547E 20°54’) as an important Marbled Teal settlement sites, probably not described to date.

  • Climatic Changes and Cultural Responses During the African
    Climatic Changes and Cultural Responses During the African Humid Period Recorded in Multi-Proxy Data David McGee, Massachusetts Institute of Technology, Cambridge MA USA Peter deMenocal, Columbia University, New York, NY USA Oxford Research Encyclopedia of Climate Science, 2017, doi: 10.1093/acrefore/9780190228620.013.529 Summary The expansion and intensification of summer monsoon precipitation in North and East Africa during the African Humid Period (AHP; c. 15,000–5,000 years before present) is recorded by a wide range of natural archives, including lake and marine sediments, animal and plant remains, and human archaeological remnants. Collectively this diverse proxy evidence provides a detailed portrait of environmental changes during the AHP, illuminating the mechanisms, temporal and spatial evolution, and cultural impacts of this remarkable period of monsoon expansion across the vast expanse of North and East Africa. The AHP corresponds to a period of high local summer insolation due to orbital precession that peaked at ~11–10 ka, and it is the most recent of many such precessionally paced pluvial periods over the last several million years. Low-latitude sites in the North African tropics and Sahel record an intensification of summer monsoon precipitation at ~15 ka, associated with both rising summer insolation and an abrupt warming of the high northern latitudes at this time. Following a weakening of monsoon strength during the Younger Dryas cold period (12.9–11.7 ka), proxy data point to peak intensification of the West African monsoon between 10–8 ka. These data document lake and wetland expansions throughout almost all of North Africa, expansion of grasslands, shrubs and even some tropical trees throughout much of the Sahara, increases in Nile and Niger River runoff, and proliferation of human settlements across the modern Sahara.

  • Modern and Early Holocene Mollusc Fauna of the Ounianga Lakes (Northern Chad): Implications for the Palaeohydrology of the Central Sahara

The confirmed modern fauna of aquatic molluscs at Ounianga comprises three widespread species (Melanoides tuberculata, Biomphalaria pfeifferi and Lymnaea natalensis), of which only the first appears to maintain a thriving population. We recovered seven more species of gastropods, among which one is new to science (Gabbiella ouniangaensis), and one bivalve species from early Holocene outcrops of diatomaceous limestone at Ounianga Serir. All species except one are known to be commonly spread between lake and river systems by birds, and in its entirety this species-rich fossil mollusc fauna of Ounianga Serir resembles that of other Saharan lake sites known to have been hydrologically isolated during the early Holocene. The impoverished modern mollusc fauna, which lacks even the widespread and opportunistic species Bulinus truncatus, may have become established relatively recently through new colonisation events, following eradication of the early Holocene mollusc fauna during a later episode of high salinity or desiccation.

The second group, Ounianga Serir, comprises fourteen lakes separated by sand dunes. Floating reeds cover almost half the surface of these lakes reducing evaporation. At 436 ha, Lake Teli has the largest surface area but is less than 10 m deep.

  • Humans As Agents in the Termination of the African Humid Period
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Frontiers - Publisher Connector REVIEW published: 26 January 2017 doi: 10.3389/feart.2017.00004 Humans as Agents in the Termination of the African Humid Period David K. Wright * Department of Archaeology and Art History, Seoul National University, Seoul, South Korea There is great uncertainty over the timing and magnitude of the termination of the African Humid Period (AHP). Spanning from the early to middle Holocene, the AHP was a period of enhanced moisture over most of northern and eastern Africa. However, beginning 8000 years ago the moisture balance shifted due to changing orbital precession and vegetation feedbacks. Some proxy records indicate a rapid transition from wet to dry conditions, while others indicate a more gradual changeover. Heretofore, humans have been viewed as passive agents in the termination of the AHP, responding to changing climatic conditions by adopting animal husbandry and spreading an agricultural lifestyle across the African continent. This paper explores scenarios whereby humans could be viewed as active agents in landscape denudation. During the period when agriculture was adopted in northern Africa, the regions where it was occurring were at the precipice of ecological regime shifts. Pastoralism, in particular, is argued to enhance Edited by: devegetation and regime shifts in unbalanced ecosystems.

Armitage E-mail: [email protected] Tel +44 (0)1784 276124 Keywords African monsoon, Lake Chad, dust, African Humid Period 1 Abstract From the deglacial period to the mid-Holocene, North Africa was characterised by much wetter conditions than today. The broad timing of this period, termed the African Humid Period, is well known. However, the rapidity of the onset and termination of the African Humid Period are contested, with strong evidence for both abrupt and gradual change. We use optically stimulated luminescence dating of dunes, shorelines and fluvio-lacustrine deposits to reconstruct the fluctuations of Lake Mega-Chad, which was the largest pluvial lake in Africa. Humid conditions first occur at ~15 ka, and by 11.5 ka Lake Mega- Chad had reached a highstand, which persisted until 5.0 ka. Lake levels fell rapidly at ~5 ka, indicating abrupt aridification across the entire Lake Mega-Chad Basin. This record provides strong terrestrial evidence that the African Humid Period ended abruptly, supporting the hypothesis that the African monsoon responds to insolation forcing in a markedly non-linear manner.
