Tanzania, Millet, 2008

Tanzania's estimated postharvest losses for millet in 2008 was 32,749 tonnes or 10.8%.

As for nutrition 118 billion kcal were lost, which is the equivalent of more than 143 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, Transport from field, and then Winnowing. 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.
