Senegal, All cereals, 2018

In 2018, Senegal's annual estimated postharvest losses were 116,609 tonnes for rice, 83,128 tonnes for millet, 68,016 tonnes for maize, 26,186 tonnes for sorghum. The highest and lowest estimated postharvest loss percentages are 16.3% for maize and 8.8% for millet. The costliest estimated postharvest losses in USD are for rice: over 75 million USD, which corresponds to 2.2% 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 Senegal, the highest postharvest losses in tonnes occur for rice in Saint-Louis, for millet in Fatick, for maize in Kolda, for sorghum in Kaffrine. Regarding the nutritional losses, the estimated rice grain lost postharvest could have met the annual energy (kcal) dietary requirements of 488,344 people.
