The key regions where coffee is grown are experiencing more and more hot days caused by climate change every year, which reduces yields and increases the price, according to the latest study by the “Climate central” research group.
Temperatures above 30 degrees Celsius are “extremely harmful” for Arabica plants, the dominant variety that makes up about 60-70 percent of global production, while they are “suboptimal” for the robusta variety that makes up most of the rest.
According to the analysis of this independent research group, the 25 countries that produce almost all the coffee in the world had an average of 47 more days of heat that harms coffee in the period from 2021 to 2025.
Five countries that account for 75 percent of global coffee production, Brazil, Vietnam, Ethiopia and Indonesia, had high temperatures for 57 days.
Kristina Dal, vice president for science in the “Climate Essential” group, said that climate change poses a serious threat to coffee production, “DW” reports.
“Nearly every major coffee-producing country is now experiencing multiple days of extreme heat that can damage coffee plants, reduce yields and affect quality. Over time, these impacts can spread from the farm to the consumer, directly affecting the quality and cost of your daily coffee,” she said.
According to the group, the recent increase in coffee prices worldwide is “at least partially” caused by extreme weather conditions in coffee-growing regions, and US tariffs on imports from Brazil also play a role.
