Climate change making a mocha-ry of wild coffee populations

Posted on in with no comments.

If you’re planning on having a cup of coffee in 68 years time, then you might want to think again. Research published in Plos One suggests that by 2080, wild populations of the world’s most popular coffee species, Arabica coffee (Coffea arabica), could be extinct due to climate change. Wild populations of Arabica coffee are important to coffee producers because of their genetic diversity and could be used to develop new strains of coffee in the future. Wild Arabica populations show a range of disease, pest and drought tolerance, all of which have potential advantages in a changing climate. If the wild population of Arabica coffee were to go extinct, coffee producers would struggle to breed coffee that could survive in new conditions. Scientists from the UK and Ethiopia used current data on wild Arabica populations and the climate in those locations to model how the climate might affect the distribution of Arabica suitable sites in the future. Once the …
