Guinea-Bissau, Millet, 2006

Guinea-Bissau's estimated postharvest losses for millet in 2006 was 1,689 tonnes or 11.2%.

As for nutrition 6 billion kcal were lost, which is the equivalent of more than 7 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 Gabú.

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.
