Coffee and cocoa are emblematic of this history. Often considered inseparable, grown in the same areas, both dependent on the London and New York stock exchanges, subject to speculative global markets, they are two topicspecific chapters of the Atlas on Regional Integration in West Africa.
There are two kinds of coffee: Arabica (Coffea arabica), cultivated at higher altitudes, and Robusta (Coffea canephora), better adapted to hot, humid regions. Arabica, which has a lower caffeine content than robusta (1.4% and 2.5% respectively), is considered more aromatic. It is more popular with consumers, whereas Robusta has a more intense body [1].
[1] Robusta is used mainly for producing soluble coffee. Its second use is in the preparation of Arabica/Robusta mixtures for inexpensive coffees.
