How Global Warming Is Killing Coffee2020|01:44
A new study has found that Robusta coffee trees don’t have as a high of a tolerance for heat as initially thought. When temperatures go slightly above the optimal temperature for the robusta tree production decreases. The optimal temperature for robusta trees is 20.5 degrees Celsius which is significantly lower than expected. Production decreases by 14% every time the temperature rises one degrees Celsius over the optimal temperature. Researchers believe the production potential of robusta could decline if temperatures continue to increase. Its production potential could decline considerably as temperatures increase under climate change, jeopardizing a multibillion-dollar coffee industry and the livelihoods of millions of farmers, Study Authors. The new information will force those in the coffee industry to reassess their switch to using robusta over arabica. Many farmers have started switching to robusta coffee as they believed it could survive heat better than arabica. It’s clear the coffee industry now must adapt it’s production methods to lessen the impact of climate change. These findings provide baseline information for coffee farmers, private sector investors, and governments to adapt their coffee production plans under climate change, - Alessandro Craparo, Study Co-Author.
