Excerpts from Books and Wikipedia
"Cameroon (population: 24 million), not as well endowed with oil or other raw materials, possesses the region’s strongest agricultural sector by virtue of its higher-latitude location and higher-relief topography. Western Cameroon is one of the more developed parts of Equatorial Africa and includes the capital, Yaoundé, and the principal port of Douala."
