Tanzania, Sorghum, 2012

Tanzania's estimated postharvest losses for sorghum in 2012 was 117,192 tonnes or 12.4%.

As for nutrition 397 billion kcal were lost, which is the equivalent of more than 481 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 Household-level storage. Highest estimated postharvest maize losses in tonnes were estimated to occur in Dodoma.

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.
