It\u2019s sometimes reported<\/a> that one in every three bites of food depends on bees. As is often the case when an easy to grasp notion spreads, there\u2019s a dose of truth and a dollop of exaggeration. <\/p>\n

The stat is based on a 2007 study<\/a> that found that 35 percent of the world\u2019s food crops depend on animal pollinators of one kind or another to enable pollination and seed production.<\/p>\n

While some crop pollination happens naturally, there\u2019s a commercial side to this as well. And that\u2019s where buzzing honey bees enter the picture. They represent by far the most commercialized provider<\/a> of pollination services, with farmers across the world paying beekeepers to ferry their hives into fields of apples and almonds so that the bees flit from flower to flower, transferring pollen and allowing the fruit and nuts to develop.<\/p>\n

My own research<\/a> has focused on the vital importance of honey bees to California\u2019s almond production, an industry worth US$11 billion<\/a> to California\u2019s economy. And in fact, almonds are also vital to the health of American beekeeping operations. <\/p>\n

As the world celebrates Honey Bee Day<\/a> on Aug. 18, I thought it\u2019d be a good time to explore the economics of beekeeping. <\/p>\n

The beekeeping business<\/h2>\n

Most of us do not think of honey bees as livestock. We tend to imagine them buzzing around flowers in the wild, minding their own business until we occasionally get in the way of their stingers. However, for the majority of honey bee colonies in the United States, thinking of them as livestock is the best characterization. <\/p>\n

Beekeepers, also known as apiarists, utilize the natural population dynamics of honey bee colonies to produce honey and provide pollination services. Beekeepers move<\/a> their colonies all over the country tracking forage to cut down on supplemental feeding costs and provide colonies with pest and disease treatments when necessary. <\/p>\n

The more than 20,000 beekeepers in the U.S. differ in how they operate, but a typical migratory pattern might go as follows: The beekeeping year begins in January waiting for almonds to bloom in California. Once almond bloom is over, the beekeeper moves colonies up through the Pacific Northwest pollinating apples and other spring-blooming crops. In May, the beekeeper takes the colonies to North Dakota to produce honey from clover, canola and sunflowers. <\/p>\n

As honey production slows in the fall, the beekeeper returns to California to await almond pollination in January, and the cycle begins all over again. <\/p>\n

It is difficult to pinpoint how many beekeepers reside in each state due to the migratory nature of beekeeping operations, however most beekeepers have at least one of their home bases in either North Dakota or South Dakota. There is a lot of potential for honey production in these areas, in fact North Dakota typically produces at least twice as much honey<\/a> as any other state.<\/p>\n

Research<\/a> has found that the beekeeping industry is dominated<\/a> by large enterprises that manage, on average, around 4,000 colonies. Such operations control about half of all U.S. bee colonies.<\/p>\n

But even as beekeepers move around to keep their bees healthy and happy, winter always takes a toll. Historically, beekeepers have expected around 15 percent of their colonies to die from October to April because of the cold temperatures and lack of winter forage. Loss rates have almost doubled to 28 percent<\/a> since the early 2000s due to<\/a> a combination of stress, pests, diseases and pesticide exposure. <\/p>\n

The actual population of honey bee colonies, however, has been little affected<\/a>. That\u2019s because beekeepers have adjusted their practices by creating more colonies going into the winter months to deal with the high loss rates. Beekeepers can create more colonies by purchasing additional queens from honey bee queen breeders<\/a> and splitting one colony into two. <\/p>\n

This comes with a cost, however, and is making beekeeping less profitable, which could eventually drive many beekeepers out of business.<\/p>\n

Bees love almonds<\/h2>\n

And more beekeepers closing down would be bad news for the world\u2019s food supply because many crops, including apples, watermelon, cherries and cucumbers, currently rely on<\/a> commercially raised honey bee colonies for pollination. <\/p>\n

Perhaps no crop needs them more than California almonds. And likewise, no single crop matters more to beekeepers\u2019 bottom lines than California almond pollination, which currently makes up over a third<\/a> of U.S. beekeeping revenues. <\/p>\n

California is the world\u2019s biggest supplier of almonds<\/a>, making up 77 percent of all production in 2017. If you have eaten an almond recently, chances are it came from a tree in California\u2019s Central Valley.<\/p>\n

Most varieties of almond trees require cross-pollination \u2013 the transfer of pollen from one tree variety to another \u2013 to produce any nuts at all. Almond trees are not wind pollinated easily, so for commercial orchards in California, this requires honey bee colonies to efficiently pollinate and produce nuts. <\/p>\n

You may be envisioning a single honey bee hive in a beautiful orchard of flowering almond trees. If so, you are partly right, but the scale is hard to fathom. <\/p>\n

Roughly 1 million acres of almond trees collectively bloom over a three-week period every February, creating spectacular scenic views but also putting enormous pressure on the farmers to pollinate them quickly. Each almond acre requires roughly two<\/a> honey bee hives, each of which typically houses one colony of about 20,000 bees. With 2 million hives needed, that\u2019s well more than half of the total U.S. hive population. <\/p>\n

The logistics of pollinating almond trees<\/h2>\n

This is quite the logistical feat so let\u2019s take a closer look to see how it\u2019s done.<\/p>\n

In 2017, beekeepers in North Dakota, Idaho, Florida and other states shipped 1.7 million colonies to California to pollinate almond trees, or about 64 percent<\/a> of the total population as of Jan. 1. The bees travel in semi-truck loads of 400 to 500 colonies each. <\/p>\n
