Ghana, Millet, 2002

Ghana's estimated postharvest losses for millet in 2002 was 17,747 tonnes or 11.2%.

As for nutrition 64 billion kcal were lost, which is the equivalent of more than 75 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, Winnowing, and then Transport from field. Highest estimated postharvest maize losses in tonnes were estimated to occur in Upper West.

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.
