Mali, Maize, 2017

Mali's estimated postharvest losses for maize in 2017 was 521,226 tonnes or 15.6%.

As for nutrition 1,819 billion kcal were lost, which is the equivalent of more than 2 million 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 Sikasso.

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.
