Africa is still an unknown continent, unknown in the sense of “not discovered” and there is still so much to discover as regards authors and other artists.
We humans are a talented species, we are flexible and imaginative. Africa, a vast continent, has been left out of the limelight as regards publicity for far too long.
I am happy to hear you are interested in science fiction. Yes, sci-fi would work in Africa, but not the time-travel stuff, “Children of men,” scientific science fiction would work well, showing the possible future, maybe a little “time-travel-come-Scrooge type story, how one can change the present by seeing into the future.

Best of luck,
