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.

Value chain

Production quantity and estimated postharvest losses in % per value chain step. Please note that once loss has occurred at harvesting, the percentage loss in the next stage is a percentage of what remained, not of the original amount.
