Botswana, Sorghum, 2009

Botswana's estimated postharvest losses for sorghum in 2009 was 2,977 tonnes or 9.9%.

As for nutrition 10 billion kcal were lost, which is the equivalent of more than 12 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 Household-level storage. Highest estimated postharvest maize losses in tonnes were estimated to occur in Central.

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.
