Botswana, Sorghum, 2020

Botswana's estimated postharvest losses for sorghum in 2020 was 1,659 tonnes or 6.6%.

As for nutrition 6 billion kcal were lost, which is the equivalent of more than 6 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 Threshing and Shelling, Harvesting/field drying, and then Transport from field. Highest estimated postharvest maize losses in tonnes were estimated to occur in Chobe.

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.
