Nigeria, Sorghum, 2021

Nigeria's estimated postharvest losses for sorghum in 2021 was 828,876 tonnes or 12.3% which had an estimated value of more than 507 million US dollar.

As for nutrition 2,851 billion kcal were lost, which is the equivalent of more than 3 million 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 Kano.
