Robusta Coffee Climate Resilience Questioned by Study
A study published on Thursday in the Wiley journal Sustainable Development disputes the common assumption that robusta coffee can better withstand climate change than other coffee varieties. The paper’s lead author, Aaron Davis, senior research leader of crops and global change at the Royal Botanic Gardens, Kew, described the belief in robusta’s superior climate resilience as an "internet myth" that originated roughly ten years ago. Davis noted that earlier research contained methodological errors, such as treating irrigated farms as ideal growing conditions and failing to account for the crop’s vulnerability to drought.
Robusta coffee, often regarded as a lower‑quality alternative to arabica beans, represents a substantial portion of the global coffee supply, with Vietnam and Brazil producing the majority of the tens of millions of bags that reach international markets each year. The study’s conclusions challenge proponents who have promoted robusta as a solution for the coffee industry to adapt to changing climate conditions. With global demand for robusta increasing, any shift in understanding about its climate tolerance affects farmers, traders and consumers alike.
A Vietnamese coffee official, quoted earlier this month, stated that climate‑change adaptation has become an immediate priority for protecting production levels rather than a distant concern. The paper concluded that previous evaluations of robusta’s climate resilience should be regarded as tentative, noting that media outlets, farmers and researchers have frequently cited robusta’s ability to tolerate heat as the sector’s response to climate challenges.
