Café Aficionado: Prized Arabica plants are in danger of extinction

Researchers at the Royal Botanic Gardens in Kew and the Environment and Coffee Forest Forum in Addis Ababa, Ethiopia looked at how climate change might make some land unsuitable for Arabica plants, which are highly vulnerable to temperature change and other dangers including pests and disease.

They came up with a best-case scenario that predicts a 38 per cent reduction in land capable of yielding Arabica by 2080. The worst-case scenario puts the loss at between 90 per cent and 100 per cent.

There is a “high risk of extinction” says the study, which was published in the academic journal Plos One.

That would be bad news for both coffee drinkers and coffee-producing countries such as Ethiopia, Brazil and Colombia, which in 2009/2010 shipped some 93 million bags of coffee around the world, worth an estimated $15.4 billion.

Most coffee is made from Arabica beans. They are prized for their genetic diversity and grow best at between 18 C and 21 C. Above that, the plants ripen too quickly — which affects taste — or grow too slowly. Other coffee stems from Robusta beans.

The study goes on to note that its results are “conservative” because it did not take into account the large-scale deforestation of the Arabica-suitable highland forests of Ethiopia and South Sudan.

  1. Thank you for keeping the subject of climate change alive. Such an important issue that we all need to keep in mind when we elect our government representatives. Also, we can do our part in many small ways by reducing our consumption of fossil fuels by driving less, and passing legislation to protect our environment.
