Abstract

The recent success in dating dry farming terraces by Optically Stimulated Luminescence (OSL) enables scholars to evaluate for the first time construction events of terraces in their true social and economic context. Presented here are 36 new ages from two study areas located along the Upper Soreq catchment, highlands of Jerusalem, Israel. Field operations were targeted at locating Bronze Age and Iron Age agricultural activities while evaluating possible methodological limitations in using OSL for dating terraces. The results convincingly show that in the Mediterranean highland environment, soil erosion and rebuilding activities have only a mild impact on the resulting OSL dating. When combining the new ages with the ~60 ages that were published previously in the study area, it is possible to conclude that in the more favorable ecological niches of the highlands of Jerusalem terraces began ca 2400–2200 years ago. This was followed by two or three waves of wide-scale terracing, taking place mainly in the last 800 years. Finally, we were able to recognize a unique ecological niche that preserved ancient (ca 2500 years old) pre-terracing activities as it was not densely covered by later terraces.
