Gambia, Maize, 2012

Gambia's estimated postharvest losses for maize in 2012 was 3,550 tonnes or 18.0%.

As for nutrition 12 billion kcal were lost, which is the equivalent of more than 15 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, Household-level storage, and then Further drying. Highest estimated postharvest maize losses in tonnes were estimated to occur in Upper 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.
