2 . A groundbreaking new study finds that coffee beans are bigger and more plentiful when birds and bees team up to protect and pollinate (授粉) coffee plants.
Without these winged helpers, some traveling thousands of miles, coffee farmers would see a 25% drop in crops, a loss of roughly $1,066 per acre of coffee. That’s important for the $26 billion coffee industry — including consumers, farmers, and corporations who depend on nature’s unpaid labor — but the research goes beyond that.
The study in the Proceedings of the National Academy of Sciences is the first to show, using real-world experiments at 30 coffee farms, that the contributions of nature — in this case, bee pollination combined with pest (害虫) control by birds — are larger than their individual contributions.
“Until now, researchers have typically calculated the benefits of nature separately, and then simply added them up, which actually underestimates the benefits biodiversity provides to agriculture and human wellbeing,” says lead expert Alejandra. “But nature is an interacting system, full of important synergies (协同). We show the ecological and economic importance of these interactions in one of the first experiments in actual farms.”
For the experiment, researchers dealt with coffee plants across 30 farms, excluding birds and bees with a combination of large nets and small bags. They tested four key situations: bird activity alone, bee activity alone, no bird or bee activity at all, and finally, a natural environment, where bees and birds were free to pollinate and eat insects like the coffee berry borer, one of the most damaging pests affecting coffee production worldwide. The combined positive effects of birds and bees on fruit set, fruit weight and fruit uniformity — key factors in quality and price — were greater than their individual effects, the study shows.
“Birds, bees, and millions of other species support our lives and livelihoods, but face threats like habitat destruction and climate change,” says Alejandra. “One important reason we measure these contributions is to help protect the many species that we depend on, and sometimes take for granted.”
