DMCC Coffee Centre Warns: Climate Volatility Threatens the Future of Global Coffee
DUBAI – September 2025 – Qahwa World – Coffee is more than a beverage. It is a lifeline for over 25 million smallholder farmers, a $200 billion industry, and a cultural anchor with more than two billion cups consumed daily. Yet today, the global coffee sector faces one of the greatest challenges in its long history, according to the DMCC Coffee Centre, part of the Dubai Multi Commodities Centre (DMCC).
In its latest report, released under the Future of Trade Agri Commodities Series, the DMCC Coffee Centre published a special edition on coffee, warning that lands where coffee has thrived for centuries may no longer be suitable for cultivation in the coming decades.
According to the report, coffee’s vulnerability to climate change is stark. Unlike many other crops, coffee can only be cultivated in limited geographical zones, often at specific altitudes and within narrow temperature ranges. Any disruption in this balance — whether through droughts, frosts, or fungal diseases such as coffee leaf rust — can devastate entire harvests. Recent years have offered a preview of this future. In Vietnam, prolonged drought cut production by 20% and exports by 10% in the 2023/24 season. In Brazil, the world’s largest producer, one of the worst droughts in history pushed Arabica prices up by more than 80% in 2024. These are not isolated events but warning signals of a changing climate destabilizing a vital crop.
Research cited in the report projects that by 2050, half of today’s coffee-growing land may become unsuitable. Arabica, which accounts for 60–70% of global production and is prized for its quality, is the most at risk. Dependent on cooler climates with clearly defined wet and dry seasons, Arabica is highly sensitive to even modest increases in temperature. Robusta, known for its greater heat tolerance, may also face challenges under worsening climate conditions.
“The reality is that producers often have customers who have pre-booked volumes months in advance,” said Mike Butler, Associate Director of Coffee at DMCC. “If crops fail, they cannot deliver. This puts enormous pressure on farmers and traders, making climate volatility the new normal.”
These pressures are already reshaping market dynamics. When Arabica prices surge, major brands increasingly turn to Robusta to fill the gap, often blending higher proportions into espresso and instant products. But as Garfield Kerr, President of the Specialty Coffee Association (SCA) and founder of Mokha1450 in Dubai, explains: “Specialty coffee consumers will notice the difference. While efforts are underway to develop specialty-grade Robusta, its flavor profile remains distinct.” This divergence could redefine what consumers drink, as well as where and how coffee is cultivated in the decades ahead.
The effects of climate change extend beyond farms to disrupt the global trade system. Shortages in Brazil or Vietnam ripple across supply chains, triggering price spikes and reshaping import decisions worldwide. Exchange-based pricing, once a reliable benchmark for roasters, is increasingly disconnected from the realities of specialty markets. Butler notes: “We are in a complex situation. Exchange pricing has become speculative and detached from the actual market, especially in premium segments.”
For smallholder farmers — who produce 80% of the world’s coffee — volatility is a fight for survival. Most lack the resources to withstand failed harvests or price shocks. When yields collapse, so too does income, jeopardizing education, healthcare, and food security for millions of families. The DMCC Coffee Centre report stresses the urgent need for investment in climate adaptation strategies that enable farmers to continue producing under increasingly hostile conditions.
Among the most promising solutions is agroforestry, where coffee is cultivated alongside trees and diverse crops to shield plants from heat, improve soil fertility, conserve water, and diversify incomes. Developing drought-resistant coffee varieties is another frontier. Kerr highlights Yemen as a potential leader, where farmers have for centuries produced resilient coffees in arid, high-temperature conditions. “I expect Yemen to become an industry leader in producing drought-resistant coffees,” he says, “because its farmers and agronomists already grow coffee in hotter climates with less water.”
The urgency of innovation extends beyond agriculture. International institutions and trade hubs must foster collaboration, data-sharing, and investment to support producers. The International Coffee Organization, in partnership with the International Trade Centre, has launched a Coffee Sustainability Support Database cataloguing more than 400 climate and sustainability initiatives worldwide. From training farmers in composting techniques to supporting cooperative-led climate projects, such efforts highlight the collective action required to build resilience.
Still, adaptation alone may not suffice without broader systemic change. Consumers increasingly demand proof that their coffee is produced sustainably and ethically, and regulators are responding with measures such as the European Union Deforestation Regulation. Compliance requires end-to-end traceability, raising costs but also creating opportunities for new technologies like blockchain and AI-powered monitoring to ensure that sustainability commitments are verifiable.
The DMCC Coffee Centre concludes that the global coffee sector stands at a crossroads. Climate change is already disrupting production, and risks are intensifying. While forecasts suggest that production could reach a record 178.7 million 60-kg bags in 2025/26, long-term threats loom over both supply and the livelihoods of millions of farmers. At the same time, solutions — from agroforestry to resilient varieties, from digital transparency to circular economy models — are emerging. The question is not whether the industry will change, but whether it can adapt quickly enough to safeguard coffee’s future.
For an industry that spans continents and cultures, the message is clear: without urgent action, climate volatility could reshape the coffee world beyond recognition. But through innovation, cooperation, and resilience, coffee can remain what it has always been — not just a drink, but a global connector, an economic pillar, and a cultural force.
