Maize is a staple food for over 300m Africans. There are several varieties of maize some of which are suitable for drought prone areas. Most African cultures produce maize in large scale thanks to modern technology and mechanization.
It is a relatively cheap form of food even to people operating on a stretched budget. It is the most popular flour that comes after wheat and rice. It is popular in most kitchens, remote enclaves on the further north and even on the southern divide of Africa.
