Modeling foraging ranges and spatial organization of Late Pleistocene hunter–gatherers in the southern Levant – A least-cost GIS approach

Abstract

This study takes a regional approach to understanding the nature of Near Eastern hunter–gatherer spatial organization near the height of the Last Glacial Maximum, circa 21,000 calibrated years ago. To do so, we reconstructed the paleogeography and paleovegetation and then employed least-cost GIS analysis to model foraging ranges and potential annual territorial extent associated with a selection of excavated and dated sites throughout the southern Levant. Settlement trends in the region as a whole are explored first, followed by a case study of annual settlement scenarios in the arid Azraq Basin on the eastern edge of the Levant, focusing on its distinctive large aggregation sites.The results of the study reveal that potential maximum daily foraging ranges as well as habitats and habitat zone heterogeneity within these foraging ranges differed greatly across the region. Due to variance in potential plant and animal productivity, settlement patterns undoubtedly differed significantly across the southern Levant particularly with respect to the number of moves per year, the importance of fusion–fission strategies, the seasonality of relocation tactics, and the importance of group territoriality. These variances in annual settlement options and emerging patterns within the southern Levant at the height of the Last Glacial Maximum provide baseline conditions for understanding divergences in adaptive trajectories within the wider region.
