干旱区生态环境知识资源中心

The present work aims at setting the bases for the critical study of settlement patterns and resource management among Holocene hunter-gatherer and agro-pastoral groups in arid margins. The case study is set on the SW margin of the Thar Desert, in N Gujarat, an ecotone sensitive to the slightest shifts in precipitation patterns (Indian Summer Monsoon). The potential significance of published and newly acquired archaeological information is discussed in the light of physiographical data collected from satellite imagery and field exploration. The review of available and newly acquired records includes: (a) The integration of field and remote observation of regional traits and (b) The definition of active morphological processes that may bias archaeological preservation and visibility. A synthetic geoarchaeological map of the study area is proposed that integrates physiographical and archaeological evidence at the regional scale. The potential significance of the archaeological evidence in the region (i.e. presence/absence/concentration of archaeological materials in different physiographical units) is discussed in terms of preservation and visibility. At this stage, results are considered at the regional level of macroscopic units. The results constitute the first step towards the full multi-scalar integration of landscape architectures, stratified archaeological sites and surface sediments at regional and local levels.
