The archaeology and ethnoarchaeology of rain-fed cultivation in arid and hyper-arid North Africa

Rain-fed cultivation in drylands—especially in arid and hyper-arid areas—is often considered to play a minor role in human subsistence. Drawing upon the results of ethnoarchaeological research in North Africa, this paper reviews non-irrigated agricultural practices in the absence of anthropogenic water-harvesting structures, and presents a proposal for how such practices can be identified in the drylands of the past. An improved understanding of the long-term development of rain-fed cultivation augments our knowledge of past land-use strategies and can inform future models of sustainable agriculture in some of the world's driest regions.
