The Delice Valley in north-central Anatolia is one of the regions where Hatti societies lived during the Early Bronze Age. This region has rarely been explored in terms of its geology, geomorphology, and human-environment interactions throughout the Bronze Age. The focus of the Delice Valley Survey is to build a holistic approach to assess complex socio-ecological dynamics in the region from the perspective of the longue duree. This paper examines the paleoclimatic conditions, the settlement systems, the production capacity of agropastoral systems, and the changes in the political economy in the Delice Valley during the Early Bronze Age and the Iron Age. The results of the first season of fieldwork suggest that the Delice Valley was settled intensively only during certain periods. Although paleoclimatically suitable for denser settlement, the area showed significantly lighter settlement patterns during the Middle and Late Bronze ages.
