Coffee and cocoa lovers around the world may soon have to bid a bittersweet farewell to their beloved beverages and treats. Not only are coffee and cocoa plants under threat from drought and diseases, but a sharp decline in insect pollinators is also causing serious problems.
The future of coffee and chocolate production has been uncertain for years, partly due to the changing climate. Coffee plants are particularly sensitive to a fungal disease known as coffee plant rust, which has devastated many plantations in Central and South America. Meanwhile, cocoa trees have been attacked by the Cacao Swollen-Shoot Virus (CSSV), which rapidly spread through West Africa.
Now, the situation is becoming even more dire. The decline in insect pollinators, such as bees and butterflies, is putting the production of coffee and cocoa at risk. Insect pollinators play a crucial role in the reproduction and fruit production of these plants. Without pollination, coffee cherries and cocoa pods cannot develop, resulting in a decline in coffee beans and cocoa beans.
A recent study shed light on the complex interrelationship between climate change, land use changes, and their impact on the diversity of pollinating insects. The researchers collected data from over 1,500 locations worldwide where crops are grown, as well as information on more than 3,000 different insect pollinators. The findings revealed a troubling trend – the combination of climate change and agricultural practices has led to significant declines in both the number and diversity of pollinators.
Approximately 75 percent of all crops depend on animal pollination to some extent, making this decline in pollinators a cause for concern. Tropical regions, including areas in Southeast Asia, northern South America, and Sub-Saharan Africa, are particularly at risk. Rising temperatures in these regions exacerbate the challenges faced by coffee and cocoa production.
The study also highlighted the potential impact on other tropical crops, including mango and watermelon. As these crops face scarcity and declining yields, the consequences are not limited to the availability and affordability of coffee and chocolate. Local economies and global trade heavily rely on these crops, and small farmers in affected regions face uncertainty about their income.
Several reasons contribute to the risk faced by these crops. For instance, cocoa trees have short-lived flowers that are primarily pollinated by a specific species of mosquito. However, the preferred environments of these mosquitoes, such as shady and moist areas, are becoming increasingly scarce due to climate change. Global warming also affects the size and flight abilities of butterflies, another important pollinator. Furthermore, many insects struggle to survive in extreme heat, making higher temperatures detrimental to their populations.
The study’s findings reinforce the critical role of pollinators in maintaining agriculture and food security. To combat the decline in pollinators, experts suggest growing natural habitat patches within agricultural land to provide safe spaces for insects. Additionally, developing new plant varieties that can self-pollinate and employing manual or artificial pollination methods are potential solutions, albeit with increased production costs.
However, the most effective approach lies in addressing the underlying problem – climate change. Urgent global action is needed to combat climate change, slow land-use changes, and protect natural habitats. Only by preserving pollinating insects can we ensure the future of coffee and chocolate production, as well as the livelihoods of those who depend on these crops.
The threat to coffee and chocolate production serves as a crucial reminder of the interconnectedness of nature and the importance of taking proactive measures to safeguard our environment and food sources. Without swift action, the decline in pollinators could drive these beloved commodities closer to extinction, leaving a bitter taste for coffee and chocolate enthusiasts worldwide.]
