Optimal coffee-growing conditions include cool to warm tropical climates, rich soils, and few pests or diseases. The world’s Coffee Belt spans the globe along the equator, with cultivation in North, Central, and South America; the Caribbean; Africa; the Middle East; and Asia. Brazil is now the world’s largest coffee-producing country.
If Earth’s climate continues to warm over the coming decades, obstacles to coffee cultivation will multiply. Consider Arabica coffee (Coffea arabica), the species grown for roughly 70 percent of worldwide coffee production. Arabica coffee’s optimal temperature range is 64°–70°F (18°C–21°C). It can tolerate mean annual temperatures up to roughly 73°F (24°C).
