How does climate change affect coffee production?

The narrative surrounding coffee and climate change often focuses on the 'disappearance' of coffee, but the reality is more nuanced: it is a crisis of stability and equity. Coffee, especially the high-value Arabica species, requires specific, stable temperature ranges. As global temperatures rise, the bioclimatic suitability of traditional growing regions is shifting, forcing production to higher altitudes or entirely new latitudes. This transition is not merely an agronomic hurdle; it is a profound economic shock for the 80% of the world’s coffee produced by smallholders. The mechanism of impact is multifaceted: extreme weather—such as prolonged droughts or intense, unseasonal precipitation—disrupts the delicate flowering and fruiting cycles of the coffee plant. Simultaneously, warmer climates expand the range of pests and pathogens, such as coffee leaf rust, which thrive in these new conditions. A common misconception is that technological fixes, such as new hybrid varieties, are a panacea. While hybrids can offer 29–61% higher output, they often demand increased labor and chemical inputs, which can trap farmers in cycles of debt and dependency. Furthermore, most global interventions prioritize 'sectoral resilience'—ensuring the supply chain remains functional for importers—rather than the 'household resilience' of the farmers themselves. True adaptation requires moving beyond simple productivity metrics to support diversified livelihoods and local, site-specific agroforestry practices that protect the soil and the farmer’s long-term economic autonomy.
