Deserts edge Sites in the Bronze age

The Desert eadge Sites as a species of settlements of the Bronze Age are composed of other Sites due to different and unfavorable living conditions. So far, a general comparison of how and why the formation, growth, and decline of all these settlements have not been done. Despite these environmental differences, analyzes and interpretations of the formation, progress, and decline of all Bronze Age sites are evaluated with the same criteria. But the marginal areas of desert are largely ecologically poor and lack many sustainable ecological factors for sustainable settlement. The study area of the desert is located between the Indus Valley and Iran and the evidence suggests that these regions appeared in the late fourth millennium, growth has been in the mid-third millennium and decline in the late third millennium and early second millennium BC and the livelihoods were initially based on agricultural and livestock resources and then at the apex of their expansion, largely on the basis of production, access to mineral and industrial, commercial and non-agricultural resources. The main questions included the livelihoods and chronology of this area and some of the goals were to identify and study the process of desert margins formation and the patterns of livelihoods in the desert, distance from the desert, It was further studied and understand the variables that represent the different livelihood, economic and productive structure of desert marginal communities from other Bronze Age sites are examined. The research method is based on historical-analytical method; The results indicate the peak of flourishing these areas in the middle of the third millennium and according to statistical comparisons, nature of many of the desert margin sites, depended on the intermediary role of these areas in economic transactions as an element and the driving force and industrial production and export of raw materials have been crucial to the development of these sites.
