Sierra Leone, Rice, 2002

Sierra Leone's estimated postharvest losses for rice in 2002 was 76,497 tonnes or 18.1%.

As for nutrition 266 billion kcal were lost, which is the equivalent of more than 317 thousand people, in terms of annual nutritional dietary energy requirements. In the value chain, the majority of the loss is estimated to be happening at Harvesting/field drying, Threshing and Shelling, and then Market storage. Highest estimated postharvest maize losses in tonnes were estimated to occur in Northern.

Value chain

Production quantity and estimated postharvest losses in % per value chain step. Please note that once loss has occurred at harvesting, the percentage loss in the next stage is a percentage of what remained, not of the original amount.
