Coffee affected by global warming 🌍
Growing coffee requires certain essential weather conditions. Arabica, for example, which accounts for 2/3 of the world market, grows at an average annual temperature of around 19°C. A climate that is vulnerable to global warming and temperature increases.
Coffee is therefore not spared from global warming. Especially since coffee species are also subject to deforestation and the spread of diseases. According to a study by the Australian Climate Institute, almost 50% of coffee plantations could suffer from rising temperatures, extreme weather conditions or the development of diseases. Worse still, nearly 60% of species are threatened with extinction.
Hope in a new species 🌱
Scientists have recently rediscovered an endangered West African wild species called “Coffea Stenophylla”. Native to Sierra Leone, the coffee species is also found in Côte d’Ivoire and Guinea but in small numbers. Coffea Stenophylla has the advantage of being grown at an average annual temperature of about 25°C, which is about 6°C higher than Arabica. There is therefore a real potential in the cultivation of Coffea Stenophylla, especially as it has similar taste characteristics to Arabica.
Aaron Davis, Director of Coffee Research at the Royal Botanic Kew Gardens, said: “Sustaining the coffee supply chain is vital to addressing climate change – coffee drives a multi-billion dollar global industry, supports the economies of many tropical countries and provides a livelihood for more than 100 million coffee farmers. Finding a coffee species that grows at higher temperatures and has excellent flavour is a unique scientific discovery – this species could be critical to the future of high quality coffee.”.
Coffea Stenophylla could therefore become an alternative to Arabica if the species continues to be affected by global warming. A hope for coffee lovers! ☕
