Forests across Africa provide food and support for millions of people. However, these natural food systems are shrinking, according to new research.
The traditional knowledge used to sustain these forest food sources is also disappearing. This knowledge is vital for harvesting and using many forest plants and animals.
The study assessed traditional and indigenous knowledge on forest and tree-based food species in Africa's biodiversity hotspots. It looked at their conservation status and how they are used.
This loss of knowledge threatens the availability of important food sources for many rural communities. It also impacts biodiversity conservation efforts.
Researchers warn that the shrinking food systems and fading knowledge could have serious consequences for food security.
Efforts to conserve both the forest resources and the indigenous knowledge are needed to protect these vital food systems.
