Where are robusta and arabica coffee grown in Cameroon?

In Cameroon, coffee cultivation is geographically distributed based on the specific requirements of the two main varieties:

• Robusta coffee: This variety, which constitutes the majority of the country's coffee crop, is grown in the warm and humid southern regions of Cameroon.1
• Arabica coffee: This variety is cultivated on the western high plateau.1

While Robusta is primarily associated with the southern lowlands, it is also grown in the western high plateau alongside Arabica. Generally, Arabica requires higher elevations—typically between 600 and 2,000 meters—to thrive in a cool subtropical climate, whereas the hardier Robusta can be grown at lower altitudes ranging from sea level to 600 meters.123
