The 3rd International Conference on Neglected and Underutilized Species (NUS): For a Food-Secure Africa featured presentations from specialists and students in the field from around the world.

A large number of interesting talks and posters were presented by conference participants over the three days. Among them, keynote addresses were delivered on the conference themes by distinguished speakers: Prof. Mary Abukutsa-Onyango, Jomo Kenyatta University of Agriculture & Technology, Dr. Yemi Akinbamijo, Director General, FARA, Ambassador Mary Mubi, Zimbabwe’s Permanent Representative to FAO, Prof. Patrick Van Damme, University of Gent, Belgium, Mr. Gus Le Breton, CEO, Bio-Innovation, Zimbabwe, and Dr. Raymond Vodouhe, Bioversity International, Benin.

Side events were also hosted during the event by Crops for the Future Research Organization, FAO, Bio-Innovation, Zimbabwe and Bioversity International on a range of topics, such as NUS in higher education and value chain development. On the last, day panel discussions on critical issues took place.
