Coffee production in Ethiopia, the birthplace of Arabica coffee, is at a critical crossroads as climate change reshapes growing conditions across the country's diverse agroecological zones [1][2].
Over 4.7 million smallholder farmers manage 95% of Ethiopia's coffee in forest-based systems that are increasingly vulnerable to rising temperatures, changing rainfall patterns, and extreme weather events [4]. Recent research reveals a complex picture: while some areas may see expanded suitability, others face significant losses, and the interaction with EU deforestation regulations creates new challenges for future production areas [6].
"Ethiopia's coffee forests are currently the lifeline for millions of people and a critical genetic resource-base for the planet. Over 95% of these forests are managed by roughly 4.7 million smallholder farmers in the highlands, and the coffee-value chain supports more than twenty-five million people across the country."

"Many areas in the region that could become newly suitable for coffee production may not be commercially viable... The heterogeneity of primary local drivers of coffee suitability means that micro-scale spatial analyses of climate change impacts on coffee production could provide valuable insights for other regions in planning targeted and effective climate adaptation strategies."
Long-term analysis across five major coffee districts reveals significant changes [10].

Wild Coffea arabica populations in Ethiopia possess remarkable ecophysiological diversity for drought adaptation [5][9].
Plants from drier, variable climates show the highest phenotypic plasticity, suggesting rapid adaptation potential to changing conditions [5].
The profound ecophysiological diversity in wild coffee populations emphasizes their importance as genetic resources for breeding climate-resilient cultivars [5][9].
"The specific adaptations to drought stress suggest a high potential for breeding of improved cultivars and stresses the need for conservation of the profound ecophysiological diversity... In-situ conservation within the evolutionary dynamic ecosystems of the natural habitat of Coffea arabica allows the preservation of genes for stress resistance as they co-evolve with their changing environment."

A 2025 study based on 44 interviews and 30 focus groups identified three types of institutions shaping climate resilience [7].
Government agencies providing information, technology transfer, and leadership development [7]
Challenges: Financial constraints, human resource shortages
Businesses and service organizations offering financial support and market linkages [7]
Challenges: Lack of modern equipment, limited reach
Unions, cooperatives, and membership organizations building community capacity [7]
Challenges: Farmers' resistance to change
"Policymakers and agricultural practitioners [must] assess the efficacy of climate interventions, identify areas for improvement, and translate these findings into practice to enhance the resilience of the coffee sector."
Institutional contributions: Information dissemination, technology transfer, financial support, leadership development [7]

"Local coffee-farmer associations often collectively manage large coffee-forest, where annual coffee-yields are well known. But how much carbon these forests store, the biodiversity benefits they provide, and which areas qualify for certified carbon projects remain poorly quantified." [4]
Coffee-based agroforestry systems provide [4]:
Dr. Belachew Gizachew: "With accurate methods, these coffee-forests could unlock significant opportunities to sell high-quality carbon credits on international markets." [4]
Current challenge: Farmers replacing coffee with khat due to unreliable income; carbon payments could provide steady alternative [4]
