Senegal, Maize, 2020

Senegal's estimated postharvest losses for maize in 2020 was 55,218 tonnes or 16.3%.

As for nutrition 192 billion kcal were lost, which is the equivalent of more than 231 thousand people, in terms of annual nutritional dietary energy requirements. In the value chain, the majority of the loss is estimated to be happening at Harvesting/field drying, Further drying, and then Household-level storage. Highest estimated postharvest maize losses in tonnes were estimated to occur in Kolda.

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.
