Gambia's estimated postharvest losses for fonio in 2021 was 34 tonnes or 11.7%.
In the value chain, the majority of the loss is estimated to be happening at Harvesting/field drying, Threshing and Shelling, and then Winnowing. Highest estimated postharvest maize losses in tonnes were estimated to occur in Central River.
