Nigeria, Rice, 2008

Nigeria's estimated postharvest losses for rice in 2008 was 425,019 tonnes or 11.9%.

As for nutrition 1,483 billion kcal were lost, which is the equivalent of more than 1 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 Kaduna.

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.
