As Halloween approaches, chocolate lovers may face a bittersweet reality as a new study highlights a lesser-known threat to cocoa production. While climate change poses risks like heat and drought, the most significant danger to cocoa crops is heavy rainfall, according to a recent peer-reviewed research led by environmental fellow Anna Lea Albright from Harvard University.
Market data reveals a sharp increase in cocoa prices over the years, with current prices around $6,000 per tonne compared to the $2,000 to $3,000 range seen since 2014. Factors such as heavy flooding in West Africa have contributed to the spike, impacting the region’s two million cocoa farmers.
Leslie Agyare, founder of Three Mountains Cocoa in Ghana, expressed concerns over the challenges posed by excessive rainfall, hindering farmers’ ability to harvest their crops. While climate change exacerbates extreme rainfall events, the study suggests potential interventions to safeguard cocoa production.
The research, focusing on Ghana as the world’s second-largest cocoa producer, identifies extreme rainfall during flowering as a key factor limiting yields. Wet conditions can lead to fungal infections like black pod disease, impacting cocoa trees in countries like Ecuador and Indonesia as well.
With warmer air holding more moisture, the study underscores the intensification of heavy rain events during the wet season. Despite El Niño reducing extreme rain risks in West Africa, the region faces drought concerns during critical periods for cocoa production.
Apart from climatic risks, the study also addresses non-climactic threats such as aging trees and illegal activities like gold mining, highlighting the need for sustainable cocoa farming practices. Experts emphasize the importance of infrastructure development and improved farming techniques to mitigate the impact of climate shocks on cocoa production.
As the challenges mount, the future of cocoa farming in West Africa remains uncertain. Rising prices and climate uncertainties may prompt shifts towards alternative chocolate sources like cocoa-free options, driven by concerns over supply chain resilience and sustainability.
Major players in the food industry, such as Nestlé, are exploring cocoa-free chocolate alternatives, signaling a potential shift in the chocolate market landscape. However, the transition away from traditional cocoa farming could have profound implications for smallholder farmers in the region, underscoring the need for sustainable solutions to secure the future of cocoa production.
