Senegal, Rice, 2012

Senegal's estimated postharvest losses for rice in 2012 was 60,329 tonnes or 13.7% which had an estimated value of more than 53 million US dollar, which corresponds to 2.1% of national agricultural GDP.

As for nutrition 210 billion kcal were lost, which is the equivalent of more than 252 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 Saint-Louis.

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.
