Africa population explosion
- Increased food production
- Improved hygiene & medicine
- Less warfare
- Settlement in peaceful lands brought by fixed boundaries
Africa’s population to have leveled off long ago. In fact, it has been exploding recently for many reasons: the adoption of crops native to the New World (especially corn, beans, sweet potatoes, and manioc, alias cassava), broadening the agricultural base and increasing food production beyond that previously possible with native African crops alone; improved hygiene, preventive medicine, vaccinations of mothers and children, antibiotics, and some control of malaria and other endemic African diseases; and national unification and the fixing of national boundaries, thereby opening to settlement some areas that were formerly no-man’s lands fought over by adjacent smaller polities.
