It would have been more helpful if you had posted a question or
comment, but I guess you were looking for info on places to go
paddling in africa.

I know nothing about paddling in africa, but you may want to check
out:

Canoeing in South Africa (Southern Book, 1991) by Rory Pennefather

also, i think there is at least one other guidebook to South Africa.
