IF had posted a nice historical outline before but I didn't save it. Hope he's around. Sure there was farming, but there's farming to feed families and then there's commercial farming which is entirely different. I don't know about Namibia so much but in other colonial countries blacks were barred from commercial farming. Now it's different. Now no one will be farming unless the socialist run government decrees it soon enough.
Thanks for the link.
