Ghana, All cereals, 2018

In 2018, Ghana's annual estimated postharvest losses were 414,426 tonnes for maize, 91,340 tonnes for rice, 39,230 tonnes for sorghum, 20,255 tonnes for millet. The highest and lowest estimated postharvest loss percentages are 18.0% for maize and 11.2% for millet. The costliest estimated postharvest losses in USD are for maize: over 142 million USD, which corresponds to 1.2% of national agricultural GDP.

Within the value chain, for all crops the majority of loss is estimated to be happening at harvesting/field drying. Within Ghana, the highest postharvest losses in tonnes occur for maize in Eastern, for rice in Volta, for sorghum in Northern, for millet in Northern. Regarding the nutritional losses, the estimated maize grain lost postharvest could have met the annual energy (kcal) dietary requirements of 1,693,066 people.
