Malawi, Maize, 2010

Malawi's estimated postharvest losses for maize in 2010 was 640,980 tonnes or 18.7% which had an estimated value of more than 147 million US dollar, which corresponds to 7.2% of national agricultural GDP.

As for nutrition 2,224 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 Household-level storage, Harvesting/field drying, and then Further drying. Highest estimated postharvest maize losses in tonnes were estimated to occur in Central Region.
