Dennis Arp was feeling optimistic last summer, which is unusual for a beekeeper these days.
Thanks to a record wet spring, his hundreds of hives, scattered across the central Arizona desert, produced a bounty of honey. Arp would have plenty to sell in stores, but more importantly, the bumper harvest would strengthen his bees for their biggest task of the coming year.
Like most commercial beekeepers in the US, at least half of Arp’s revenue now comes from pollinating almonds. Selling honey is far less lucrative than renting out his colonies to mega-farms in California’s fertile Central Valley, home to 80% of the world’s almond supply.
But as winter approached, with Arp just months away from taking his hives to California, his bees started getting sick. By October, 150 of Arp’s hives had been wiped out by mites, 12% of his inventory in just a few months. “My yard is currently filled with stacks of empty bee boxes that used to contain healthy hives,” he says.
This shouldn’t be happening to someone like Arp, a beekeeper with decades of experience. But his story is not unique. Commercial beekeepers who send their hives to the almond farms are seeing their bees die in record numbers, and nothing they do seems to stop the decline.
A recent survey of commercial beekeepers showed that 50 billion bees – more than seven times the world’s human population – were wiped out in a few months during winter 2018-19. This is more than one-third of commercial US bee colonies, the highest number since the annual survey started in the mid-2000s.
Beekeepers attributed the high mortality rate to pesticide exposure, diseases from parasites and habitat loss. However, environmentalists and organic beekeepers maintain that the real culprit is something more systemic: America’s reliance on industrial agriculture methods, especially those used by the almond industry, which demands a large-scale mechanization of one of nature’s most delicate natural processes.
Environmental advocates argue that the huge, commercially driven proliferation of the European honeybees used on almond farms is itself undermining the ecosystem for all bees. Honeybees out-compete diverse native bee species for forage, and threaten the endangered species that are already struggling to survive climate change. Environmentalists argue a better solution is to transform the way large-scale agriculture is carried out in the US.
Like all bees, honeybees thrive in a biodiverse landscape. But California’s almond industry places them in a monoculture where growers expect the bees to be predictably productive year after year.
Commercial honeybees are considered livestock by the US Department of Agriculture because of the creature’s vital role in food production. But no other class of livestock comes close to the scorched-earth circumstances that commercial honeybees face. More bees die every year in the US than all other fish and animals raised for slaughter combined.
“The high mortality rate creates a sad business model for beekeepers,” says Nate Donley, a senior scientist for the Center for Biological Diversity. “It’s like sending the bees to war. Many don’t come back.” (...)
This year Arp’s bees, like more than two-thirds of the United States’ commercial honeybee population, will spend February in the toxic chemical soup of California’s Central Valley, fertilizing almonds one blossom at a time.
Pesticides are used for all kinds of crops across the state, but the almond, at 35m lb a year, is doused with greater absolute quantities than any other. One of the most widely applied pesticides is the herbicide glyphosate (AKA Roundup), which is a staple of large-scale almond growers and has been shown to be lethal to bees as well as cause cancer in humans. (The maker, Bayer-owned Monsanto, denies the cancer link when people use Roundup at the prescribed dosage. So far this year three US courts have found in favour of glyphosate users who developed forms of lymphoma; thousands more cases are pending.)
On top of the threat of pesticides, almond pollination is uniquely demanding for bees because colonies are aroused from winter dormancy about one to two months earlier than is natural. The sheer quantity of hives required far exceeds that of other crops – apples, America’s second-largest pollination crop, use only one-tenth the number of bees. And the bees are concentrated in one geographic region at the same time, exponentially increasing the risk of spreading sickness. (...)

The high price of growth
When the phenomenon called colony collapse disorder was first identified in 2006, after a record number of honeybees mysteriously disappeared or died outside their hives, it was linked to a variety of factors including loss of habitat and climate change. But the primary culprit was pesticides. Researchers found that a class of pesticides called neonicotinoids was especially lethal to bees.
Last May, the EPA pulled a dozen “neonics” from the market following a successful lawsuit brought by beekeepers and environmental groups.
But there are many chemicals that are not labeled as bee toxic, even though they can make bees sick and weaken their immune systems. While bees may survive the pollination season, they may not last the winter or may take back substances that gradually poison the entire colony.
Those on the almond growers’ side acknowledge there is a huge problem. “The bee mortality rate is too high and is unacceptable,” says the entomologist Bob Curtis, a pollination consultant for the Almond Board of California. “It is only because of the hard work and creativity of beekeepers that [almond growers] have gotten the bees they need.”
The almond board’s “best practice” guidelines encourage beekeepers to spend as little time in California’s Central Valley as possible. Honeybees can travel up to three miles in search of varied forage, so even if the almond grower is doing everything right to protect a pollination investment, the cotton or grape farmer down the road may be spraying bee-toxic chemicals on crops.
Even as almond production has steadily ramped up for decades, the number of commercial hives in the US has remained at a steady 2.7m colonies since the early 2000s. With all the challenges beekeepers face, just maintaining the bare minimum is a struggle.
