South Africa is a country and north africa is a general geographic location.
Food will not stop the starvation. It would just make people dependant on it. Education in how to farm and produce food, stable governments, infra structure and roads would start solving the problem.
About 3000 miles
Most of northern Africa falls in and around the Sahara desert. So preach farming all you want to the sand. Crops won't grow. South Africa was heavily colonized by Germany and has a large population of German descendants and other caucasian races. The country can be compared to a poor European country, with very rich, middle class, and the endless poverty Africa is known for.
South Africa also has similar climate to Europe, which enabled agricultural to take off and thrive, while it failed farther north. People seem to forget that people lived in Africa first. If agriculture did well there it would have already been implemented. Most of Africa is terrible for growing the crops we depend on in the west.
Colonization in Africa can also be attributed to a lack of diseases; Africa is the only continent in colonial history that repelled European invadors with indigenous forms of disease. These diseases weren't prevalent in south Africa, however as settlers moved farther north they fell victim to completely unknown diseases. Any other questions?
