South Africa, Wheat, 2022

South Africa's estimated postharvest losses for wheat in 2022 was 11,404 tonnes or 4.3%.

As for nutrition 37 billion kcal were lost, which is the equivalent of more than 42 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 Household-level storage, Harvesting/field drying, and then Market storage. Highest estimated postharvest maize losses in tonnes were estimated to occur in Western Cape.

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.
