Cote d'Ivoire was estimated to have exported 28 000 tonnes of maize over the same period, including 22 000 tonnes to Mali. Consequently, it is difficult to evaluate the growing interdependence between policies, flows and production, biasing interpretation of the real capacity of supply to meet food demand. This information is an essential contribution in food security and nutrition policies and provides the basis for calculating food energy supply. Consumption of maize H and sorghum is overestimated and H of rice underestimated.
