“…At Qasr al‐Deir, Tallet et al (2012) and Bravard, Mostafa, Cargia, et al (2016) describe yardangs derived from spring mound deposits that incorporate Roman pottery. In the Dakhla Oasis, Bravard, Mostafa, Davoli, et al (2016) also described spring mounds that also captured sediment, in that case, accumulated from irrigation soils.…”

Holocene large lake development and desiccation: Changing habitats in the Kharga Basin of the Egyptian Sahara

The Sahara Desert, known today as one of the world's great wildernesses, was periodically dotted with large lakes that formed during the Holocene pluvial periods. As the lakes dried, the fertile and flat‐lying damp muds formed a rich habitat that was occupied by human settlers before being abandoned, as the area dried out completely. In Kharga, our work shows that a combination of pluvial periods with short term storage in the Upper Nubian aquifer, access to artesian water in the Lower Nubian Aquifer and over‐flow water from the Nile via the Wadi Toshka created a biodiverse environment which, although drier today, sustained refugia of plants and animals throughout the Holocene.

“…Let us consider the question at the broader regional scale of the Western desert of Egypt oases. Recent geoarchaeological surveys in Dakhla oasis (260 km southward from Bahariya), in the ancient town of Trimithis, revealed evidence of irrigation dating from the end of the Third Intermediate Period (840-740 BCE) to the 3rd century CE (Bravard et al 2016b). Several successive phases of sediment accretion or deflation were observed, reflecting periods when, respectively, wind-blown particles were trapped by the roughness of humid cultivated soils or, on the contrary, drying of the environment and crop decline were accompanied by significant wind erosion of soils.…”

The End of the “Green Oasis”: Chronological Bayesian Modeling of Human and Environmental Dynamics in the Bahariya Area (Egyptian Sahara) from Pharaonic Third Intermediate Period to Medieval Times

et al. 2019

After the sharp transition to aridity that followed the “Green Sahara” episode 5500 years ago, human settlements took refuge in Egyptian oases, which have to varying extents been “Green Oases” for centuries. In that period, synchronous with the beginning of historical times, the desert’s aridity is generally regarded as broadly comparable to the current period. Natural and anthropogenic deposits studied during 13 excavation campaigns in Bahariya Oasis (Egyptian Desert) suggest that a fairly clear transition from a relatively green environment to much more arid landscapes occurred in the first millennia BCE and CE. This article aims at establishing the chronology of human occupations and environmental change within this period, by combining archaeological and radiocarbon data, using Bayesian modeling. It reveals that the drying up of the environment experienced by desert farmers occurred at some point between the reigns of Antoninus Pius and Caracalla (2nd–3rd century CE). The accuracy of the produced chronological models made it possible to highlight synchronisms between the end of this “Green Oasis” phase and comparable aridification phenomena on regional and interregional scales. Similar degradation processes on remote sites inside the Roman Empire might be explained by globalized anthropogenic agencies overlapping with a broader climatic drying.
