Yet again we are reminded of the reality in this story from PERC.
You’ve heard the story: Honeybees are disappearing. Beginning in 2006, beekeepers began reporting mysteriously large losses to their honeybee hives over the winter. The bees weren’t just dying—they were abandoning their hives altogether. The strange phenomenon, dubbed colony collapse disorder, soon became widespread. Ever since, beekeepers have reported higher-than-normal honeybee deaths, raising concerns about a coming silent spring.
The media swiftly declared disaster. Time called it a “bee-pocalypse”; Quartz went with “beemageddon.” By 2013, National Public Radio was declaring “a crisis point for crops” and a Time cover was foretelling “a world without bees.” A share of the blame has gone to everything from genetically modified crops, pesticides, and global warming to cellphones and high-voltage electric transmission lines. The Obama administration created a task force to develop a “national strategy” to promote honeybees and other pollinators, calling for $82 million in federal funding to address pollinator health and enhance 7 million acres of land. This year both Cheerios and Patagonia have rolled out save-the-bees campaigns; the latter is circulating a petition calling on the feds to “protect honeybee populations” by imposing stricter regulations on pesticide use.
A threat to honeybees should certainly raise concerns. They pollinate a wide variety of important food crops—about a third of what we eat—and add about $15 billion in annual value to the economy, according to the U.S. Department of Agriculture. And beekeepers are still reporting above-average bee deaths. In 2016, U.S. beekeepers lost 44 percent of their colonies over the previous year, the second-highest annual loss reported in the past decade.
But here’s what you might not have heard. Despite the increased mortality rates, there has been no downward trend in the total number of honeybee colonies in the United States over the past 10 years. Indeed, there are more honeybee colonies in the country today than when colony collapse disorder began.
Beekeepers have proven incredibly adept at responding to this challenge. Thanks to a robust market for pollination services, they have addressed the increasing mortality rates by rapidly rebuilding their hives, and they have done so with virtually no economic effects passed on to consumers. It’s a remarkable story of adaptation and resilience, and the media has almost entirely ignored it.
The Bee Business
The chief reason commercial beekeeping exists is to help plants have sex. Some crops, such as corn and wheat, can rely on the wind to transfer pollen from stamen to pistil. But others, including a variety of fruits and nuts, need assistance. And since farmers can’t always depend solely on bats, birds, and other wild pollinators to get the job done, they turn to honeybees for help with artificial insemination. Unleashed by the thousands, the bees improve the quality and quantity of the farms’ yields; in return, the plants provide nectar, which the bees use to produce honey.
Honeybees are essentially livestock. Their owners breed them, rear them, and provide proper nutrition and veterinary care to them. Unlike bumblebees and wasps, honeybees are not native to North America; the primary commercial species, the European honeybee, is thought to have been introduced by English settlers in the 17th century.
Commercial beekeepers are migratory. They truck their hives across the country in tractor trailers on a journey to “follow the bloom,” stacking their hives on semis and moving at night while the bees are at rest. Most travel to California in the early spring to pollinate almonds. After that, they take their own routes. Some go to Oregon and Washington for apples, pears, and cherries; others to the apple orchards of New York. Some pollinate fruits and vegetables in Florida in the early spring, followed by blueberries in Maine.
Like any such transit project, accidents happen—as when one beekeeper, Lane Miller, crashed his truck in a canyon near Bozeman, Montana, in 2014. More than 500 hives—about 9 million sleepy, angry bees—spilled onto the roadway. “The bees were so agitated you could barely see the beekeepers or the wreckage itself,” said the local fire chief at the time. After 14 hours, hundreds of stings, and a crew of emergency beekeepers, the road finally reopened.
Still, the migration is mostly uneventful. After blooming season, beekeepers shift their focus from pollinating crops to making honey. Many commercial crops that require honeybee pollination, such as almonds and apples, do not provide enough nectar for the bees to produce surplus honey. So in the summer, beekeepers often head to the Midwest, where they essentially pasture the bees, turning their hives loose in fields near sunflower, clover, or wildflowers, which supply large amounts of nectar and allow the bees to make plenty of honey. When summer ends, the beekeepers truck their bees back south to spend the winter in warmer climates.
Some observers claim that this annual migration is contributing to colony collapse. As the food writer Michael Pollan put it in The New York Times in 2007, “the lifestyle of the modern honeybee leaves the insects so stressed out and their immune systems so compromised that, much like livestock on factory farms, they’ve become vulnerable to whatever new infectious agent happens to come along.” But it is precisely this modern-livestock lifestyle and the active markets for pollination services that have allowed non-native honeybees to flourish on our continent. They are the reason honeybee populations have remained steady even in the face of disease and other afflictions.
The Fable of the Bees
Before the 1970s, it was widely believed among academics that the pollination industry’s very existence was a problem. In a 1952 paper, the appropriately named economist J.E. Meade argued that honeybee pollination was an “unpaid factor” in apple farming, since orchard owners and beekeepers did not coordinate their production decisions. Both produce what economists call “positive externalities,” or spillover benefits for the other, causing inefficiencies. Since “the apple-farmer cannot charge the beekeeper for the bee’s food, which the former produces for the latter,” Meade believed that certain “subsidies and taxes must be imposed.” (Indeed, Washington established a honey price-support program in 1952 with the goal of promoting pollination. The program was briefly eliminated in 1996, but has since been resurrected.)
But then another economist, Steven Cheung, investigated how the honeybee pollination market actually worked. In a 1973 study, he found plenty of contracting between beekeepers and orchard owners to overcome the problem Meade had identified. All he had to do was open the yellow pages of the phone book to find listings for pollination services. “The fable of the bees,” as Cheung called it, was blackboard theorizing. Real-life farmers and beekeepers were solving this problem on their own.
Sometimes the farmers paid the beekeepers to pollinate their crops; other times the beekeepers paid the farmers for the right to place hives in their orchards. It all depended on which activity—pollination or honey production—generated more value in that instance. Sometimes the exchange involved both money and honey. Meade, meanwhile, had gotten his central example backward: Apple pollination does not yield much honey, so the beekeeper charges the apple farmer, not the other way around.
