Sierra Leone, Maize, 2012

Sierra Leone's estimated postharvest losses for maize in 2012 was 13,352 tonnes or 23.8%.

As for nutrition 46 billion kcal were lost, which is the equivalent of more than 55 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 Market storage. Highest estimated postharvest maize losses in tonnes were estimated to occur in Northern.

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.
