Another possibility just popped into my head: maybe Israel and Jewish culture? They don't directly own such a great resource rich land, but they do have a cultural heritage which strongly supports them. We see that all around us.
I don't see anything coming out of Africa, that is for sure.
I don't know enough to totally dismiss something like a Turkey/Muslim civilization resurgence. They are far fallen from their integrity of centuries past. So any recovery would seem to me to be, if possible at all, centuries in the future.
