Kenya, Maize, 2012

Kenya's estimated postharvest losses for maize in 2012 was 653,659 tonnes or 17.4% which had an estimated value of more than 267 million US dollar, which corresponds to 2.0% of national agricultural GDP.

As for nutrition 2,366 billion kcal were lost, which is the equivalent of more than 2 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, Household-level storage, and then Further drying. Highest estimated postharvest maize losses in tonnes were estimated to occur in Rift Valley.
