Understanding the impact of climate stressors on coffee yield is crucial for farmers and researchers. This study focuses on how different climate factors affect coffee production in Yunnan, China. Researchers examined four main stressors: drought, chill, and heat stress, using advanced statistical models. They analyzed a vast dataset to identify critical growth stages and the most influential climate indicators.
• The flowering stage is the most affected by drought stress, with higher vapor pressure deficit (VPD) leading to significant yield losses.
• Chill stress during the maturity stage shows that lower temperatures can drastically reduce coffee yield, with a notable loss for each degree drop.
• Heat stress has a lesser impact but is still a factor to consider, especially in certain regions.
• The study highlights spatial variations in stressors, with drought stress being most severe in central areas and chill stress affecting the northwest.
Understanding these impacts is vital for developing strategies to mitigate climate effects on coffee production. As climate change progresses, knowing how to adapt and protect coffee yields becomes increasingly important for the industry and local economies.
