“…Most of Southern Africa has a mean precipitation rate of between 50 and 250 mm per year and, overall, precipitation is highly variable. While the average rainfall in South Africa is 495 mm, only 35% of the country receives precipitation of 500 mm per year or more, and 21% of the country receives less than 200 mm of precipitation per year (Food and Agriculture Organization (FAO), 2006; Redelinghuys & Pelser, 2013).
