Availability of annually reproducing wild yam species (Dioscorea praehensilis and Dioscorea semperflorens) is considered to be a key factor for the viability of forest hunter-gatherer subsistence in the African rainforests. I here describe the habitat and distribution of wild yam patches, and discuss possible human impacts on the formation of wild yam patches, which currently support long-term forest expeditions by Baka hunter-gatherers in southeastern Cameroon. An analysis of canopy…

TLDR
The issue of whether exploitation of wild yams, including searching for them, digging them up, transporting them to the camp, and cooking and consuming them, could have been practiced in everyday life remains inconclusive.
CENTRAL AFRICAN FORESTS AS HUNTER-GATHERERS' LIVING ENVIRONMENT: AN APPROACH TO HISTORICAL ECOLOGY
While tropical rainforests in central Africa are often assumed as "green desert" where human cannot live by entirely depending on wild food resources, recent studies suggest that hunter-gatherers
Ecological and Edaphic Drivers of Yam Production in West Africa
Yam is an important food and cash crop in West Africa (the yam belt) whose production is traditionally nonsedentary due to its substantial nutrient demand. Population growth, urbanization, and

Much of our success as a species derives from the ability to adapt hunting and gathering to diverse ecologies and incorporate a wide range of food resources. Hunter–gatherers maintain broad dietary
Addressing the wild yam question: how Baka hunter-gatherers acted and lived during two controlled foraging trips in the tropical rainforest of southeastern Cameroon
We designed observational surveys of controlled foraging trips of Baka hunter-gatherers in Cameroon to verify the ‘wild yam question’—i.e. is it possible for human beings to live without agricultural

Growth and Nutrient Use Efficiencies of Yams (Dioscorea spp.) Grown in Two Contrasting Soils of West Africa
TLDR
The nutrient use agronomic efficiencies indicated the impact of both N and K in promoting yields especially under nonfertilized conditions and the beneficial impact of fertilizer on yields was significantly lower in the fertile forest soils.
