Malawi, Wheat, 2009

Malawi's estimated postharvest losses for wheat in 2009 was 349 tonnes or 12.7%.

As for nutrition 1 billion kcal were lost, which is the equivalent of more than 1 thousand 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 Household-level storage. Highest estimated postharvest maize losses in tonnes were estimated to occur in Southern Region.

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.
