Conclusions
➢The portfolio approach makes use of location-specific data to not only
capture the socio-ecological dynamics of smallholder food production
diversity but uniquely includes individual food consumption data to inform
knowledge on local dietary gaps.
➢16 location-specific food tree and crops portfolios in East Africa developed
→ flexibility of methodology + potential to scale geographically
➢Food composition data for 90+ food tree species & underutilised crops,
can inform prioritisation of crops for mainstreaming in local (and global)
food systems
➢The portfolios and the database are important tools to support decision-
making for recommending healthier food production in local food systems.
