Mauritania, All cereals, 2021

In 2021, Mauritania's annual estimated postharvest losses were 10,958 tonnes for rice, 10,468 tonnes for sorghum, 2,848 tonnes for maize, 444 tonnes for millet. The highest and lowest estimated postharvest loss percentages are 17.2% for maize and 8.8% for millet. The costliest estimated postharvest losses in USD are for rice: over 12 million USD.

Within the value chain, for all crops the majority of loss is estimated to be happening at harvesting/field drying. Within Mauritania, the highest postharvest losses in tonnes occur for rice in Trarza, for sorghum in Hodh ech Chargui, for maize in Gorgol, for millet in Hodh ech Chargui. Regarding the nutritional losses, the estimated rice grain lost postharvest could have met the annual energy (kcal) dietary requirements of 45,057 people.
