Uganda, Maize, 2003

Uganda's estimated postharvest losses for maize in 2003 was 402,352 tonnes or 17.2%.

As for nutrition 1,456 billion kcal were lost, which is the equivalent of more than 1 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, Household-level storage, and then Further drying. Highest estimated postharvest maize losses in tonnes were estimated to occur in Eastern.

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.
