Important to bear in mind this is only a projection, and trendlines change with human effort and choices, but in this case the recent revisions have been upward--the world should work to change that.
This is one of the lower estimates and yes obviously depends on many things including various natural constraints. There are also higher estimates and as as time goes on all of them have been adjusted upwards.
All the same for them to fall away significantly either TFR needs to fall or life expectancy will. Given the population of Africa was 100 million just over a century ago and it it set to double by 2050, that would be an increase of 2500% in 150 years.
