9000 years of human resilience


The evolution of Lake Abhe’s paleoshorelines reveals 9000 years of human resilience in the face of climate change

by Lamya Khalidi

In a study published in Quaternary Science Reviews, a multidisciplinary archaeology-geoscience collaboration involving French and Ethiopian teams led by Lamya Khalidi, a researcher at the CNRS (CEPAM, University Côte d’Azur), has led to the description of the first Holocene human occupation sequence (from 11000 to 3300 before the present) and the discovery of the first known potter-pastoral sites in the Ethiopian Afar. Based on the study of 7 recently discovered archaeological sites in the Abhe paleolake basin, this team from the CEPAM, Geoazur, the French Center for Ethiopian Studies (CFEE), TRACES, MNHN, IPGS-EOST, Palévoprim and the Ethiopian Authority for Research and Conservation of Cultural Heritage (ARCCH) has carried out a reconstruction of the fluctuations of the level of Lake Abhe in relation to human occupation strategies by correlating new archaeological and geomorphological data and 37 new C14 dates. Over a period of 9000 years, the sites cover two major humid-arid transitions of the African Humid Period (AHP) during which the water level of Lake Abhe varied by more than 5000 km2 and hunter-gatherers turned to herding. This study reveals that the establishment of mixed economies was mainly in response to highly fluctuating environmental conditions in one of the world’s most arid regions.
