A Free Tool to Help Farmers Pick the Right Coffee Trees for 2050
Planting a coffee tree is a 20-year bet on the future. You’re picking a variety today that has to survive droughts, temperature swings, and disease pressure that won’t fully reveal themselves until the 2040s. Get it wrong, and the tree underperforms — or dies — long before it pays for itself.
That’s the central problem World Coffee Research (WCR) and the Alliance of Bioversity International and CIAT are trying to solve with CafeClima, a free web platform launched this week that matches climate projections with actual variety performance data from trials spanning 23 countries.
What CafeClima Actually Does
The platform walks users through a five-step process. Pick a location, and CafeClima pulls up localized climate data — current conditions and projections for 2050 using internationally recognized datasets (NEX-GDDP, CHIRPS, CHIRTS, WorldClim). Then it finds “climate twins”: trial sites around the world that already have the climate your farm is heading toward. If your plot in Huila, Colombia is going to feel like a particular valley in Central America by 2050, the platform shows how 26 different arabica varieties performed in that analog environment.
The performance data comes from WCR’s International Multilocation Variety Trial (IMLVT), a decade-long research effort that’s tested the world’s top-performing arabica varieties across 18 countries. It’s the largest dataset on coffee variety performance ever assembled, covering everything from yield and disease resistance to cup quality across dramatically different growing conditions.
“The world needs to replace billions of coffee trees,” said Dr. Jennifer “Vern” Long, WCR’s CEO. “The only thing more costly than inaction is action without insight.”
The Scale of the Problem
The numbers paint a stark picture. Research suggests roughly half the land currently suited for arabica production could become unsuitable by 2050. Across the coffee belt, an estimated 4 million hectares of aging trees need replacement — an area equivalent to the combined coffee footprint of Brazil, Vietnam, Colombia, and Ethiopia.
Yet only about 5% of the world’s 11.5 million smallholder coffee farmers have received any kind of investment support for renovation. A 2025 TechnoServe report pegged the total cost at $4 billion over seven years. Roughly $1.2 billion has been invested in coffee renovation and rehabilitation over the past two decades — a fraction of what’s needed.
Without better data, that money risks being wasted. A farmer who replants with a variety that can’t handle the heat or rainfall patterns of 2040 hasn’t just lost a few years — they’ve lost the productive life of the tree.
Who Funded It
TechnoServe supported the platform’s development with funding from the U.S. Department of Agriculture. UK tea-and-coffee company Taylors of Harrogate and German specialty roaster Coffee Circle provided additional targeted funding. WCR itself is backed by more than 200 member companies across 30 countries.
Dr. Eric Rahn of the Alliance of Bioversity International called CafeClima “a unique decision-support tool that informs climate-resilient coffee combining variety selection with climate information able to reduce future uncertainty.”
Why This Matters
Most farmers replanting today rely on local knowledge, nursery availability, or whatever a government extension program recommends. Those are reasonable starting points, but they don’t account for where the climate is heading over the next two decades. CafeClima doesn’t replace local expertise — it adds a layer of global data that didn’t exist in accessible form before.
The platform is free, available in English and Spanish, and aimed not just at farmers but at the agronomists, funders, and investors who shape replanting decisions across the supply chain. You can explore it at cafeclima.worldcoffeeresearch.org.
For coffee drinkers, the stakes are personal: the beans in your bag five or ten years from now depend on which trees get planted this season. CafeClima is trying to make sure the right ones go in the ground.
