Spatial and Temporal Variation in Mesopotamian Agricultural Practices in the Khabur Basin,Syrian Jazira

While archaeologists have long recognized the value of regional analysis to define economic systems, relatively few archaeological data sets—principally settlement patterns, ceramics and lithics—have been used to assess regional-scale spatial variation and temporal change. As with other archaeological data sets, resolution of archaeobotanical data at a regional scale poses some formidable challenges. A new approach in the Near East uses archaeobotanical remains from multiple sites. The data have been drawn from midden assemblages that exhibit high variability between assemblages, requiring the use of random effects logistic regression models that can accommodate high variability. Our approach detects changes over time and over geographical region and tests the statistical significance of these changes. Results show a significant rise in crop-processing wastes, most probably from a specialized focus on barley processing at settlement and storage sites during the 3rd millenniumbc (Ninevite 5 and Early Jazira Periods). This shift to a greater representation of barley-processing by-products represented in middens can most probably be linked with an emerging specialization in pastoral production and re-settlement in arid regions of the northern Mesopotamian steppe in the 3rd millennium bc.
