Rwanda, Maize, 2008

Rwanda's estimated postharvest losses for maize in 2008 was 27,444 tonnes or 16.4% which had an estimated value of more than 9 million US dollar, which corresponds to 0.7% of national agricultural GDP.

As for nutrition 99 billion kcal were lost, which is the equivalent of more than 116 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, Further drying, 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.
