Speaking as an African... You don't know what you are talking about. Most of the starvation is caused by dumb ass politicians. Zimbabwe on its own could probably feed most of Africa, unfortunately all the farms got stolen by Mugabe and "redistributed" which means given to the party faithful and families of politicians none of whom have a clue how to run a commercial farm.
All the rest of the starving countries have similar dumb political problems.
In central Africa the ground is so fertile you can literally toss an apple core on the ground and come back 3 weeks later to see an apple tree starting to grow.
Run properly Africa could probably feed most of the world.
