Bees are responsible for pollinating key crops like apples, and their decline now threatens crop yields. Pikist
Without bees, future generations may not be able to identify with adages like, ‘An apple a day keeps the doctor away.’
Crop yields for key crops like apples, cherries and blueberries are down across the U.S. because of a lack of bees in agricultural areas, a Rutgers University-led study published Wednesday in The Royal Society found. This could have “serious ramifications” for global food security, reported The Guardian.
The scientists wanted to understand the degree to which insect pollination, or lack thereof, actually limits current crop production. Surveying 131 locations across major crop-producing areas of the U.S., they found that five out of seven crops showed evidence of “pollinator limitation” and that yields could be boosted with full pollination, the study said.
“The crops that got more bees got significantly more crop production,” said Rachael Winfree, an ecologist and pollination expert and the senior author of the paper, reported The Guardian. “I was surprised, I didn’t expect they would be limited to this extent.”
The research further noted that pollinator declines could “translate directly” to decreased production of most of the crops studied and that wild bees “contribute substantially” to the pollination of most studied crops.
Declines in both managed honeybees and wild bees raise serious concerns about global food security, the study said, because most of the world’s crops rely on pollinators.
Bees and other pollinators like bats and birds underpin the global food system, but their populations are dwindling due to human activity including settlement building, pesticide use, monoculture farming and climate change. This is part of what many are calling the “insect apocalypse,” a precipitous decline in insects across the globe.
