Global Warming May Shift Where Coffee Is Grown

Perennial US Barista Championship Finalist Sam Lewontin recently talked to TechInsider about global warming and how it may affect where some of the best coffee in the world is grown. Always thoughtful, Lewontin provides an interesting perspective to how rising temperatures could change the future of coffee.

Coffee is generally produced in what is known as the “Coffee Belt”, an imaginary plane stretching around globe between the Tropics of Cancer and Capricorn where the temperature is most suitable for growth. But as the article notes:

…as temperatures in high-altitude coffee-growing regions warm, Lewontin said, the range of altitude in places that have been considered to be strong coffee origins narrows: “So lower altitudes are staying the same, and the band in which you can grow tasty coffee is sort of moving up the mountain.”

And as the temperatures climb, ideal coffee growing conditions may start to expand outside of the Coffee Belt.

This may seem like a good thing, but with the growing girth of the band, the regions in the center — those that once harbored ideal coffee growing conditions — will become too hot. This means that specific regions that are now perfect, such as those in Colombia, Brazil, Ethiopia, and Kenya, may soon become fallow.

And hotter temperatures bring on other challenges, like “roya”, or leaf rust, a devastating disease that thrives in hotter temperatures and can wipe out entire crops. The article mentions that many countries are taking steps to combat the issues that come with hotter temperatures, including experimenting with new coffee hybrids. It also posits that some parts of the world that have traditionally grown robusta—including Vietnam, India, and Uganda—may see a push towards growing arabica in the future.

The whole article can be found here and definitely worth a read.
