Mean threats:
Average age of coffee farmers in Latin America is 56 year
Prices on the world market are versatile
Climate change is causing many problems in (arabica) coffee
plantations (e.g. new pests)
Will we drink coffee in the future?
Yes, we will still drink our cup of coffee
if we look for alternative species in Africa
if we bring back the knowledge to Africa
if we will develop the coffee farms in Africa

We identified during our research a species endemic in Kivu:
Morphologically resembling to Arabica
Genetically closely related to Arabica
Ecologically similar to Arabica
11. 1111Coffea: a botanist‘s view on Coffee
Aim of the project:
Characterizing the species
Conserving the species in/ex-situ
Multiplying the species
Testing the organoleptic characteristics
>> in order to introduce the species in culture and make it
available for farmers and breeders in the RD
Congo
