Woody Plants in Dialan and other Ritual Practices within the Biocultural Landscape of Niokolo Koba National Park, Senegal
We examine the ritual use of woody species in seven villages near Niokolo Koba National Park in Senegal, focusing on tree-based rituals within the Dialan belief system. Local communities reported 41 species used in rituals, with Khaya senegalensis, Piliostigma thonningii, Daniellia oliveri, and Anogeissus leiocarpa being the most frequently mentioned. Among these, Khaya senegalensis, Ceiba pentandra, Adansonia digitata, and Ficus gnaphalocarpa ar…
Chemical and isotopic analyses reconstruct multi-scalar copper circulation networks in West Africa
For the past 50 years, copper sourced from the Akjoujt region has been inferred primarily through the enrichment of arsenic in metal samples from archaeological sites in West Africa. However, arsenic is common to a variety of mineral deposit types and this signature was based on early low-resolution spectroscopic data. Here, we apply lead isotopic and bulk chemical analyses to copper metal and ore samples from the region of Akjoujt, in order to i…
Local Communities and Protected Areas
Biodiversity conservation approaches in Africa have often separated human societies from nature, establishing protected areas with restricted resource use and displacing local communities. However, successful conservation and management strategies demand the integration of social and environmental priorities. To this end, we examined the use of woody plants by rural communities around the Niokolo Koba National Park (Senegal). We quantitatively as…
Études archéologiques du peuplement de la moyenne vallée du fleuve Sénégal
Cet article fait la synthèse des résultats de recherches archéologiques faites dans la moyenne vallée du fleuve Sénégal depuis les années 1990. La moyenne vallée du fleuve Sénégal a une écologie riche et diversifiée. Cette zone d’abondance, dans un contexte sahélien, a très tôt attiré les populations victimes des fluctuations de l’isohyète 400 mm. La tradition orale et les sources arabes affirment que la zone fut dominée par des États comme le Té…
A story of abandonment
The authors present a new, interdisciplinary project focusing on the interaction between people and the landscape within abandoned and populated villages following the founding of Niokola-Koba National Park in south-eastern Senegal. In this article, they assess anthropogenic transformations from geoarchaeological, ethnoarchaeological and ethnobotanical perspectives in order to document and preserve the heritage of both displaced and settled agric…
The Shell Midden Sites of Senegambia
There are hundreds of shell midden sites along the Senegambian coastline. The shell middens were first formed during an eustatic event known as the Nouakchottien marine transgression (6,800–4,000 bp). During that marine transgression, the sea shoreline was pushed back hundreds of miles in the interior. This engendered the flourishing of malacological fauna and several fish species. As a result of this, several natural shell midden were formed. Fr…
Ancient Developments in the Middle Senegal Valley and the Inland Niger Delta
The study of West Africa has contributed to the expansion of comparative arid-lands floodplain prehistory, from both the data collection (cultural and historical) and the theoretical aspects. The neoevolutionary approach that often pictures Africa as a backward continent has been successfully challenged. In the Middle Senegal Valley and in the Inland Niger Delta, research on their societies’ complexity done along these two subcontinent’s floodpla…
Genetic Structure of the Western and Eastern African Sahel/Savannah Belt and the Role of Nomadic Pastoralists as Inferred from the Variation of D-Loop Mitochondrial DNA Sequences
The objective of this study was to provide deeper knowledge of the maternal genetic structure and demographic history of the human populations of the Sahel/Savannah belt, the extensive region lying between the Sahara and tropical rainforests, spanning from the Atlantic Ocean to the Red Sea coast. The study aimed to confijirm or disconfijirm archaeological and linguistic data indicating that the region’s populations underwent diversifijication as …

Internal diversification of non‐Sub‐Saharan haplogroups in Sahelian populations and the spread of pastoralism beyond the Sahara
BACKGROUND: Today, African pastoralists are found mainly in the Sahel/Savannah belt spanning 6,000 km from west to east, flanked by the Sahara to the north and tropical rainforests to the south. The most significant group among them are the Fulani who not only keep cattle breeds of possible West Eurasian ancestry, but form themselves a gene pool containing some paternally and maternally-transmitted West Eurasian haplogroups. MATERIALS AND METHODS…

Excavations at Walaldé
Excavation of the five hectare site of Walaldé revealed an occupation by iron-using agropastoralists that began [800–550] cal BC, and continued until [400–200] cal BC. The earliest occupation phase appears to document a period of transitional iron use, with some worked stone in evidence. Smelting and forging slags and tuyeres are present in considerable quantities in the later phase. Copper with the distinctive chemical signature of the Akjoujt m…
