Sognigbe N’Danikou investigates the biological determinants and socioeconomic incentives for domestication of wild-harvested and threatened indigenous edible tree species in West Africa. Model species include Vitex doniana Sweet, Synsepalum dulcificum (Schumach. & Thonn.) Daniell, and Sclerocarya birrea (A.Rich.) Hochst. He focuses on seed ecology and crop physiology investigations to develop agronomic techniques, and modelling the structure-function of species to define sustainable harvesting practices, while quantitative ethnobotany is used to investigate local knowledge and incentives for community engagement in domestication of species.
