Guinea-Bissau's estimated postharvest losses in tonnes for maize ranged from 1,164 tonnes in 2011 to 4,977 tonnes in 2013. The estimated loss percentages have been unchanged over time at 18.0%.
Within the value chain, the majority of the postharvest maize loss is estimated to be happening at Harvesting/field drying. In Guinea-Bissau, on average the highest quantity of maize production occurs in Oio. Regarding nutritional losses, the number of people whose annual energy (kcal) dietary requirements could have been met with the estimated maize lost postharvest ranged from 4,840 people in 2011 to 20,694 people in 2013.
