Water availability and landuse during the Upper and Epipaleolithic in southwestern Syria

Paleolithic research often assumes that environmental conditions played a major role in shaping human evolution. To study this relationship we present a spatially explicit approach based on the assumption that the distribution of water within the landscape is an essential component of local environmental conditions. Here, we analyze the relation of wetness and human landuse patterns from the Upper Paleolithic (UP) and Epipaleolithic (EP) of Western Syria. In particular the spatially explicit character of the approach enables the detection of a significant change in landuse patterns during the UP and EP accompanied by a significant shift in the wetness characteristics of the preferentially used areas. These results are discussed against the background of published data on climatic conditions in order to identify both a possible time frame and triggers for this change in landuse. While we conclude an increased influence of natural conditions on the spatial behavior for the UP, we suggest an additional influence of cultural circumstances in shaping EP spatial behavior. For the region studied we argue that the bounded pattern observed during the UP changes to a spatially flexible pattern during the Late Natufian.
