Cameroon, Maize, 2008

Cameroon's estimated postharvest losses for maize in 2008 was 306,221 tonnes or 22.0% which had an estimated value of more than 154 million US dollar, which corresponds to 4.5% of national agricultural GDP.

As for nutrition 1,068 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 Household-level storage, Harvesting/field drying, and then Further drying. Highest estimated postharvest maize losses in tonnes were estimated to occur in West.
