Tanzania, Maize, 2022

Tanzania's estimated postharvest losses for maize in 2022 was 789,762 tonnes or 17.9%.

As for nutrition 2,858 billion kcal were lost, which is the equivalent of more than 3 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 Mbeya.

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.
