Climate variability is creating significant challenges for global agriculture, particularly within the cocoa sector. In the Amazon, research indicates that cocoa production is expanding sustainably through family farming on small properties, with minimal impact on recent deforestation in regions like Pará and Rondônia.

However, new research from Harvard University and Ghana suggests that excessive rainfall poses a major threat to global cocoa harvests. Intense rain during sensitive stages like flowering can ruin crops and promote fungal diseases. In Ghana, the combination of excessive rain during the wet season followed by extreme drought accounts for approximately two-thirds of year-to-year yield fluctuations, a trend also observed in Ecuador and Indonesia. These climate-driven fluctuations have contributed to significant volatility in global cocoa prices.
