Malawi, Wheat, 2004

Malawi's estimated postharvest losses for wheat in 2004 was 231 tonnes or 12.5%.

As for nutrition 765 million kcal were lost, which is the equivalent of more than 0 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 Market 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.
