A recent peer-reviewed study highlights a lesser-known risk faced by cocoa production amidst the festive display of Halloween chocolates across stores nationwide. While climate change’s impact on cocoa cultivation has mostly centered on heat and drought, researchers reveal that heavy rainfall poses a more significant threat to cocoa crops.
The surge in cocoa prices in recent years, with a tonne now priced at around $6,000 US, has been attributed to various factors, including heavy flooding in West Africa, a key cocoa-producing region with over two million farmers. Leslie Agyare, founder of Three Mountains Cocoa in Ghana, expressed the challenges posed by excessive rainfall on this year’s cocoa crop.
The study, focusing on Ghana as the world’s second-largest cocoa producer, found that extreme rainfall during flowering stages significantly impacts cocoa yields. The excess moisture can harm delicate cocoa flowers and young pods, leading to lower production. Furthermore, wet conditions increase the risk of fungal infections like black pod disease, affecting cocoa output in countries like Ecuador and Indonesia.
As climate change intensifies extreme rainfall events, farmers face escalating difficulties in cocoa cultivation. While traditional risks like aging trees and illegal mining also threaten cocoa production, experts emphasize the need for interventions such as fungicides and improved drainage systems to mitigate these challenges. Infrastructure investments and operational changes are crucial for enhancing cocoa farming practices and safeguarding future production against climate shocks.
