Nigeria, Rice, 2020

Nigeria's estimated postharvest losses for rice in 2020 was 954,142 tonnes or 11.7% which had an estimated value of more than 970 million US dollar.

As for nutrition 3,329 billion kcal were lost, which is the equivalent of more than 4 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 Winnowing. Highest estimated postharvest maize losses in tonnes were estimated to occur in Niger.
