The land is useless if people have no clue what to do with it
As the report says, "two game farms in the northern province of Limpopo are the first to be targeted for unilateral seizure "
I know the area well. Game farms are established in areas that are largely infertile, but can support indigenous wildlife [that evolved to live in these areas]. If you are good at wildlife management, good at dealing with people, good at providing an international scale of hospitality - lodging, cuisine, wines and liquors - good at providing high quality guides, good and serving either the photographic safari crowd or the hunting safari crowd (and the business do not mix together at all) and build up a rep over a number of years you can make a marginally profitable go of the venture. Lacking any of that, just one thoroughly disgusted client reporting on the internet, and your business will tank in a heartbeat.
With capital, water, and high tech agricultural equipment you might be able to turn the land into some sort of farming operation (although the fact that it hasn't suggests that that is no a profitable option - there is a reason it is a game farm). But small landholding production will not support the farmers farming it much less an extended population.
It's sort of like socializing a space-rocket factory. It's rocket science and you will very quickly be out of the rocket business.
Or no willingness to work your butt off to produce.
