You will notice that the opening paragraph in that article in African Farming acknowledges this, and reads as follows:
"In 2024, despite poor grain and oilseed harvests, South Africa’s agricultural exports set a new record of $13.7 billion (about R253 billion)."
(Emphasis mine)
And as Earnest noted, that drought they had is now well and truly over. (Either a drought or a flood - sounds a bit like Australia!)
