Zambia, Sorghum, 2002

Zambia's estimated postharvest losses for sorghum in 2002 was 2,208 tonnes or 13.1%.

As for nutrition 8 billion kcal were lost, which is the equivalent of more than 9 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, Household-level storage, and then Threshing and Shelling. Highest estimated postharvest maize losses in tonnes were estimated to occur in Copperbelt.

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.
