The evo- lutionary journey shaped by gathering, eating and trading habits is largely overlooked. In Cameroon, a country undergoing a food transition, the Agropolis Foundation's 'Arbopolis' project used a participatory approach that brought together growers, consumers and researchers to demonstrate the importance of safou (the fruit of Dacry- odes edulis) in diet and cultural practices. These findings will bolster the resilience of local food systems and sup- port the sustainable management of this species' genetic resources. 076 ; 098 ; 082
