Kenya, Maize, 2007

Kenya's estimated postharvest losses for maize in 2007 was 469,364 tonnes or 17.3% which had an estimated value of more than 94 million US dollar, which corresponds to 1.4% of national agricultural GDP.

As for nutrition 1,699 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, Household-level storage, and then Further drying. Highest estimated postharvest maize losses in tonnes were estimated to occur in Rift Valley.

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.
