Researchers at the National Center for Agronomic Research (CNRA) in Ivory Coast are developing climate-resilient cocoa bean varieties to combat the adverse effects of climate change on cocoa production. This initiative is crucial for a country that produces nearly 40% of the world’s cocoa and relies heavily on the crop for its economy, which contributes 15% to the national GDP and supports approximately five million people.
As climate change leads to unpredictable rainfall patterns, cocoa farmers like Kofi Alexis Amani have witnessed the detrimental impact on their crops. “You can lose everything,” Amani lamented, highlighting the urgency of the situation. The CNRA’s geneticist, Caudou Trebissou, explained that researchers are cross-pollinating cocoa plants to create offspring that can withstand varying levels of water stress. So far, they have identified 11 promising bean varieties that they plan to introduce to the market.
Impact of Climate Change on Cocoa Production
Rainfall in Ivory Coast has been declining since the 1980s, with average annual precipitation dropping to around 1,100 millimeters, significantly below the 1,200 to 2,000 millimeters required for optimal cocoa growth. Maryse Assi, an agronomist at CNRA, noted that this reduction in rainfall has led to decreased flowering and fruit production, as well as declines in soil fertility. Farmers are experiencing firsthand the consequences of these changes, with reports of dry branches and small cocoa pods.
Adaptive Strategies by Farmers
In response to these challenges, farmers are adopting innovative planting strategies. Amani, for instance, has diversified his plantation by interspersing cocoa trees with cashew, iroko timber, and banana trees. This approach not only provides shade for the cocoa pods but also helps retain moisture in the soil. Such adaptive measures are essential as Ivory Coast braces for more extreme weather events, including droughts and heavy rains, predicted to become more frequent in the coming decades.
The urgency of this research is underscored by projections that suggest a potential 20% decline in cocoa production by 2050 if no action is taken. Yves Brahima Kone, head of the cocoa industry’s regulatory body, emphasized the importance of scientific advancements for the future of cocoa orchards in the country. As temperatures continue to rise, with an increase of 1°C recorded between 1991 and 2020, the need for resilient agricultural practices becomes ever more critical.
As the world’s largest consumer of chocolate products, Europe relies heavily on Ivorian cocoa exports, making the success of these research efforts vital not only for local farmers but also for global chocolate supply chains. According to a report by Gulf Today, the future of cocoa production in Ivory Coast hinges on the successful development of these climate-resilient bean varieties.
