For sure it's whites losing their land. There used to be around 55,000 whites, it's now down to 25,000, mostly from South Africa and German descent. They own farms in the semi-desert south-east, where they farm with sheep, and along the eastern border, and then across the north-central part, where they are mostly catlle and game farmers. More than 50% of the Namibian population of just over 1.5 million lives in the far northern parts, where the fertile Okavango delta is. Very little of that land is owned by whites. The land earmarked for redistribution is that in the central and eastern parts. Namibia already imports most food, and has a very small and sensitive economy that can be totally destroyed by something like this. I don't know why the politicians deem it necessary to go this way, there is no way they will lose any elections.
FWIW: I have a coin from "Ostafrika" from 1912; I think that is Tanzania today. Haven't seen any from Cameroon or German West Africa yet, though I'm sure they made some.
