I'll make prediction that by 2035 South Africa will be indistinguishable from any other African dungheap nation. The infrastructure will be barely functioning, with constant power outages, no running water and sewage being drained into the rivers untreated. the major cities will look like something out of a post-apocalypse movie and the citizenry will be back to barely subsisting on whatever bushmeat they can scrounge up.

From what I have been reading, all that you mention is already starting to happen.
