 This study assesses the sensitivity of coffee yields to temperature and precipitation variation from 1974 to 2017 in Brazil, identifies which coffee producing regions have the highest exposure to climate hazards due to high dependence on coffee production as a proportion of agricultural area and generates a vulnerability index to identify which regions are least able to adapt to climate hazards. The study finds that historical climate change has already resulted in reductions in coffee yield by more than 20% in the southeast of Brazil, with minus Gerais, the largest coffee producing state in Brazil, having among the highest climate hazard and overall climate risk. Negative climate hazard and exposure impacts for coffee producing regions could be potentially offset by targeting climate adaptation support to these high-risk regions.
