Senegal's estimated postharvest losses for fonio in 2016 was 762 tonnes or 23.6%.

In the value chain, the majority of the loss is estimated to be happening at Harvesting/field drying, Threshing and Shelling, and then Market storage. Highest estimated postharvest maize losses in tonnes were estimated to occur in Sédhiou.
