摘要

Large distribution of historical agricultural installations in the desert zone of the southern Levant, mainly from the Byzantine - Early Muslim periods (1600-1000 y BP) indicates that the region was highly productive in the past. That could have been achieved either because of a more humid climate, or by sophisticated runoff harvesting techniques utilized by the ancient farmers under a desert climate. Among all, the most important factor enabling the existence of the desert agriculture was runoff harvesting. Our study assess a multi-disciplinary approach testing the relationship between diverse geological strata, their ability to cause runoff and the possible preferences made by the ancient farmers to utilize these rock properties. Utilizing GIS methods we generated high-resolution maps, highlighting the present runoff potential both on a single lithology slope level and on the drainage basin scale. By applying this methodology we show that high correlation (80%) exists when testing the spatial emplacement of runoff-farming installations constructed during the Byzantine - Early Muslim periods on the present best runoff yielding drainage basins under the present climatic conditions. This hints at the long, stability of the environmental and probably climatic conditions in the southern Levant regions during the late Holocene. (C) 2016 Elsevier Ltd. All rights reserved.
