There May Not Be One "Cure-All" Climate-Resilient Coffee

What to know:

Climate-related issues, including warmer temperatures, unpredictable weather, and coffee diseases like coffee leaf rust, continue to threaten global coffee production
In recent years, coffee varieties like robusta have been touted as “answers” to climate change; however, recent research shows that robusta coffee isn’t as climate-resilient as previously believed
A study published in October of 2026 shows that growing coffee varieties in environments they’re compatible with may matter more than focusing on a single “cure-all” climate-resilient coffee variety

As climate change continues to pose a threat to the global coffee industry, researchers and producers are still searching for coffee varieties capable of withstanding warmer temperatures, unpredictable weather, and disease. Several months ago, a study was published by the journal Sustainable Development that challenged the widely-held notion that robusta coffee is more climate-resilient than arabica. Now, even newer research suggests that there may not be a single variety equipped to handle climate change.

The study, which was published in Scientific Reports in October of 2026 and funded by member companies of World Coffee Research, examined how different arabica coffee varieties perform across a wide range of growing conditions. Researchers evaluated 32 varieties at 30 sites across 17 countries, comparing their yields and susceptibility to coffee leaf rust: one of the most prominent threats to coffee production. Explains the study: “Identifying varieties that combine high productivity with disease resistance across diverse environments is critical for climate adaptation.”

Different climates, different results

One of the study’s biggest findings was the importance of what the researchers call “genotype-by-environment interactions.” In other words, location matters more than you’d think—and a coffee variety that thrives in one environment may not perform the same way somewhere else.

Researchers found that yield stability was closely associated with temperature. Some varieties were better adapted to cooler environments, while others performed better in warmer climates with more stable temperatures. Coffee leaf rust was more complicated, with disease severity influenced by a combination of temperature, rainfall, humidity, and temperature variability.

The study also highlighted several promising varieties. F1 hybrids H1 Centroamericano and EC16 demonstrated the strongest overall combination of productivity and coffee leaf rust resistance, followed by the introgressed variety Parainema. However, the researchers note that these varieties still had “distinct climatic preferences and trade-offs in yield stability.”

The study also indicated that, under projected 2025-2055 climates, coffee will shift toward favoring warmer climates, with sites such as Buginyanya (Uganda), Copán (Honduras), and Flor Amarilla (El Salvador) becoming increasingly representative of future coffee-growing climates.

Redefining “climate-resilient” coffee

Another notable finding was the performance of introgressed, or hybrid, varieties—arabica coffees containing genetic material introduced from other coffee species. According to the researchers, these varieties “consistently outperformed pure arabica varieties,” while pure arabicas demonstrated lower yields and greater susceptibility to coffee leaf rust.

For the coffee industry, the findings complicate the idea of a universally “climate-resilient” coffee variety. Instead of searching for one coffee capable of thriving everywhere, climate resilience may require identifying which varieties are best suited to specific growing environments.

Ultimately, the researchers say their findings provide a foundation for “climate-informed variety deployment and breeding strategies.” As growing conditions continue to shift, understanding the relationship between variety and environment could help the industry more than fixating on a single “cure-all” variety.
