Late Holocene economic specialisation through aquatic resource exploitation at Kobadi in the Méma,Mali

Following the last humid phase of the Late Holocene, human groups left the Saharan latitudes of northern Mali at around 2500 cal. years BC to settle further south. The Kobadi population was among the first Neolithic human groups to enter the Niger Inland Delta in central Mali. People adapted to their new environment by intensifying one of their former subsistence practices, namely fishing. The rich and diversified ichthyofauna exploited was dominated by large Nile perches and a variety of catfish taxa. It testifies to relatively stable hydrological conditions: a fluvial lake which was probably linked permanently to the main Niger River. Fish were caught with harpoons and probably also with diverse fishing devices such as nets, baskets and fences. Preparation processes prior to cooking cannot be determined, but fish were probably cooked on hot coals or stones, the left‐overs of the meals being discarded randomly at the site. Intense exploitation of the aquatic environment near Kobadi provided an abundant, secure and predictable source of protein. Besides fish and riparian mammals, reptiles such as turtles, monitors and crocodile were hunted. Domestic cattle provided milk and/or meat. These animals were either raised at the site or obtained by means of exchange with pastoral groups roaming the hinterlands. From the 2^nd millennium BC, the focus on aquatic resources at Kobadi, mostly through the intensification of fish exploitation, may demonstrate the beginning of economic specialisation in the Niger Inland Delta.
