Botswana, Sorghum, 2007

Botswana's estimated postharvest losses for sorghum in 2007 was 698 tonnes or 5.7%.

As for nutrition 2 billion kcal were lost, which is the equivalent of more than 2 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.
