Tanzania, Rice, 2005

Tanzania's estimated postharvest losses for rice in 2005 was 94,334 tonnes or 11.7%.

As for nutrition 337 billion kcal were lost, which is the equivalent of more than 409 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, Threshing and Shelling, 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.
