Rwanda, All cereals, 2018

In 2018, Rwanda's annual estimated postharvest losses were 69,193 tonnes for maize, 19,190 tonnes for sorghum, 15,064 tonnes for rice, 1,882 tonnes for wheat. The highest and lowest estimated postharvest loss percentages are 16.3% for maize and 12.4% for sorghum. The costliest estimated postharvest losses in USD are for maize: over 20 million USD, which corresponds to 0.8% of national agricultural GDP.

Within the value chain the majority of loss is estimated to be happening at harvesting/field drying for maize, at harvesting/field drying for sorghum, at harvesting/field drying for rice, at household-level storage for wheat. Within Rwanda, the highest postharvest losses in tonnes occur for maize in Eastern, for sorghum in Eastern, for rice in Eastern, for wheat in Northern. Regarding the nutritional losses, the estimated maize grain lost postharvest could have met the annual energy (kcal) dietary requirements of 294,806 people.
