Rwanda, Sorghum, 2018

Rwanda's estimated postharvest losses for sorghum in 2018 was 19,190 tonnes or 12.4%.

As for nutrition 65 billion kcal were lost, which is the equivalent of more than 76 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 Eastern.

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.
