This study employs an array of quantitative methods to analyze village agricultural practices during a time of regional urban abandonment at the end of the Early Bronze Age in the Southern Levant. Coordinated cluster and canonical discriminant analyses of stratified archaeobotanical assemblages from the village of Tell Abu en-Ni’aj, Jordan support a detailed portrait of changing crop management at a sedentary agrarian community during Early Bronze IV, a period marked by widespread mobile pastoralism. Our quantified analyses of carbonized plant remains are augmented with stable isotope composition data for major cultigens to offer an innovative perspective on Early Bronze IV agrarian life in the northern Jordan Valley. Seeds from seven occupation phases spanning the time period from about 2500 to 2200 cal BC indicate increasing primary reliance on Hordeum vulgare (hulled barley), and only modest cultivation of wheat, mostly Triticum dicoccum (emmer) over this time span. Constrained incremental sum of squares (CONISS) cluster analysis and canonical discriminate analysis (CDA) illustrate significant shifts in crop cultivation, and possibly related animal management, including a major transition at about 2375 cal BC. Our analyses further highlight the most important plant taxa that contributed to these shifts. Cultivated crops, wild species and chaff are more ubiquitous in the earlier phases at Tell Abu en- Ni’aj, while percentages of H. vulgare and ubiquities of Lens culinaris (lentil) increase in the later phases. Lower seed densities, weed ubiquities and chaff to cereal ratios suggest more distant crop processing after about 2375 cal BC. Values of Δ13C for the major cereals, which provide a proxy for water availability, indicate dry farming of barley and preferential watering of wheat. This study proposes that a suite of changes occurred between the earlier and later phases at Tell Abu en-Ni’aj, which portray generally diminished, more remote crop production, possibly amid greater drought stress, leading to village abandonment. We illustrate a multi-faceted analytical approach suitable for interpretation of comparable archaeobotanical evidence and inference of agrarian dynamicselsewhere in prehistory.
