Early-Holocene environments in the Wadi Faynan, Jordan

Evidence for early-Holocene environments in the Wadi Faynan in the rift-margin in souther Jordan is described. The early Holocene of Jordan is not well known and palynology, plant macrofossils and molluscs from Wadi Faynan provide evidence for a much more humid-forest-steppe and steppe-environment than the present stony desert and highly degraded steppe. The early-Holocene fluvial sediments in the Faynan catchment are predominantly fine-grained, epsilon crossbedded and highly fossiliferous. They provide convincing evidence for meandering perennial rivers before 6000 cal. BP. It is probable that this early-Holocene landscape was disrupted by the impact of early farmers and by climate change-the 8.1 ka event appears to be marked by desiccation. By the Chalcolithic, environmental degradation was well advanced.

The Haua Fteah, Cyrenaica (Northeast Libya): renewed investigations of the cave and its landscape, 2007

The 1950s excavations by Charles McBurney in the great Haua Fteah cave in northeast Libya revealed a deep (14 m) sequence of human occupation going back at least 100,000 years, with evidence for the presence of both Neanderthals and Modern Humans in the Pleistocene, and for Neolithic farmers in the Holocene. In 2007 a renewed programme of archaeological and geomorphological investigation began with the objective of improving understanding of the caves occupation sequence and, combined with fieldwork in the landscape, of the history of landscape change and human responses to it. The initial season of fieldwork removed the upper c. 4.5 m of backfill in the McBurney trench; established the robustness of the original faces and their suitability for analytical interventions; recorded detailed running sections spanning from the present day to (at least) the Last Glacial Maximum c. 20,000 years ago; and indicated the potential of the surviving archaeology to reveal not just sequence but also activities or ‘taskscapes’ at the site. The geomorphological fieldwork identified rich sequences of later Quaternary deposits (marine, colluvial, alluvial, aeolian) with the potential to provide significant results regarding the history of climate and environment in the region. Archaeological survey around the cave indicates that the variability of the surface lithic evidence appears to reflect real differences in past human behaviour and use of the landscape and not just post-depositional taphonomic processes. Fifty years after the extraordinary pioneering work of McBurney and his colleagues, the new work demonstrates the continued potential of the Haua Fteahs unique occupation sequence and the multi-period ‘human landscapes’ around it to transform understanding of early human societies in North Africa.

Reconnaissance investigation of the palynology of Holocene wadi deposits in Cyrenaica, Libya

Pollen assemblages from the base of silty alluvium in three wadi-fills in Cyrenaica are described. They show evidence for forest clearance and cultivation, including the likely cultivation of olive. This suggests that the samples are broadly of Graeco-Roman age, and that the silty alluvium started to accumulate in these wadis as the result of the landscape impact of agricultural expansion.
