The Neolithic and ‘Pastoralism’ Along the Nile: A Dissenting View

A largely accepted paradigm in African recent prehistory considers pastoralism to be the main subsistence source of food-producing communities along the Sudanese Nile valley from the 6th millennium cal BC onwards. This paradigm is constraining the development of a wider theoretical perspective that assumes, instead, a regionally differentiated picture of the economic and social organisation of local communities in northeastern Africa. This paradigm is thus the strongest impediment to achieving reliable and convincing syntheses of the transition from food collection to food production in this area. New data from Upper Nubia and central Sudan open the way for different and more complex scenarios and a new understanding of the local transition from agro-pastoral to agricultural practices. A more systematic data-based approach helps to change radically our perception of different Neolithic trajectories. Moreover, it helps to place in a different perspective—based on various levels of identity formation processes—change and continuity along the chrono-cultural sequence, as well as the different meanings that each local group confers on apparently similar acts in the context of the funerary ideology.

     

Mesolithic Site Formation and Palaeoenvironment Along the White Nile (Central Sudan)

The Mesolithic period represents a key stage in the human history of Sudan, but its complexity is not yet fully understood. Since the beginning of prehistoric research in this region, efforts were made to understand Mesolithic site formation processes and post-depositional disturbances. Responsibility for the destruction of most Mesolithic sites’ deposits rests mainly on later use of the ancient mound-like settlements as burial places by Meroitic and post-Meroitic people. Excavations at several sites in the El Salha and Al Khiday areas (White Nile, south of Omdurman) have provided recent progress in our knowledge of Mesolithic living structures in their palaeoenvironmental contexts. Detailed stratigraphic and geoarchaeological investigations enabled us to distinguish, within the sequences identified at excavated mounds, the existence of basal archaeological strata still in situ that had remained unaffected by subsequent anthropogenic disturbances and to understand the functional aspects of several archaeological features associated with Mesolithic living floors. This offers the opportunity to reassess the Mesolithic cultural sequence in the region and reconsider some statements on the economic and social aspects of Mesolithic life and landscape exploitation strategies.     

Wild Food: Plants,Fish and Small Animals on the Menu for Early Holocene Populations at al-Khiday,Central Sudan

Al-Khiday, located on the bank of the White Nile in Sudan, offers an exceptionally preserved stratigraphic sequence, providing a unique opportunity to use organic residue analysis to investigate diet and subsistence during the Khartoum Mesolithic and the Early Neolithic, a period of nearly 3500 years (7000–4500 cal BC). While the vast and diverse Mesolithic fish assemblage indicates a strong reliance on products from aquatic habitats, floodplains, vegetated marshes, and open water, results from the lipid residue analysis suggest that the fish were not cooked in ceramic pots, but consumed in other ways. Rather, pots were more specialized in processing plants, including wild grasses, leafy plants, and sedges. These results, confirmed by experimental analysis, provide, for the first time, direct chemical evidence for plant exploitation in the Khartoum Mesolithic. Non-ruminant fauna (e.g., warthog) and low lipid-yielding reptiles (e.g., Adanson’s mud turtle and Nile monitor lizard), found in significant numbers at al-Khiday, were likely also cooked in pots. There is little evidence for the processing of wild ruminants in the Mesolithic pots, suggesting either that ruminant species were not routinely hunted or that large wild fauna may have been cooked in different ways, possibly grilled over fires. These data suggest sophisticated economic strategies by sedentary people exploiting their ecological niche to the fullest. Pottery use changed considerably in the Early Neolithic, with ruminant products being more routinely processed in pots, and while the exploitation of domesticates cannot be confirmed by a small faunal assemblage, some dairying took place. The results provide valuable information on Early and Middle Holocene lifeways in central Sudan.
