Parkia biglobosa, the African locust bean, is a perennial deciduous tree in the family Fabaceae. It is found in a wide range of environments in Africa and is primarily grown for its pods that contain both a sweet pulp and valuable seeds. Where the tree is grown, the crushing and fermenting of these seeds constitutes an important economic activity. Various parts of the locust bean tree are used for medicinal and food purposes. As a standing tree, locust bean may have a positive effect on the yield of nearby crops, like other leguminous plants.

Coffea stenophylla, also known as highland coffee or Sierra Leone coffee, is a species of Coffea originating in West Africa. As of 2020, it is not commercially cultivated, because its low yield and small berries make it inferior to the two economically dominant species Coffea arabica and Coffea canephora (robusta). Research is being done to evaluate the sensory and agronomic benefits of commercially cultivating it as a method of expanding the genetic diversification of global coffee stock and increasing resilience to both climate change and crop disease pressures.
