New Model of Climate-Change Effects on Coffee Availability and Bee Pollinators

Areas in Latin America suitable for growing coffee face predicted declines of 73-88 percent by 2050. However, diversity in bee species may save the day, even if many species in cool highland regions are lost as the climate warms. The research, co-authored by David Roubik, senior scientist at the Smithsonian Tropical Research Institute, will be published in an early online Proceedings of the National Academy of Sciences edition between Sept. 11-15.

“For my money, we do a far superior job of predicting the future when we consider both plants and animals (or in this case the bees) and their biology,” Roubik said. “Traditional models don’t build in the ability of organisms to change. They’re based on the world as we know it now, not on the way it could be as people and other organisms adapt.”

A research team modeled impacts for Latin America, the largest coffee-growing region under several global-warming scenarios—considering both the plants and the bees. The team consisted of bee experts from the Smithsonian in Panama; the International Center for Tropical Agriculture in Vietnam; the Tropical Agricultural Research and Higher Education Center in Costa Rica; Conservation International and the University of Vermont in the U.S.; CIRAD in France; and CIFOR in Peru.
