Costa Rica has long ranked among the world's leading coffee producers and exporters, thanks to its volcanic soil, mild climate, and abundant rainfall. In recent years, however, persistent high temperatures and drought have been eroding its growing environment.

With water shortages during the flowering period, greater susceptibility to disease, aging trees, and labor shortages piling up, export volumes and foreign exchange earnings are coming under pressure. Faced with these challenges, the government has launched a low-carbon coffee program, while research institutions are promoting drought-resistant varieties and adaptive farming methods in an effort to cushion the impact of climate change.
