Many Mainers earn their livelihoods from harvesting bounty — including blueberries and lobsters — from the land and sea.

And Samuel Belknap and Kourtney Collum, the first students to enroll in the University of Maine’s new anthropology and environmental policy doctoral program, want to preserve those storied traditions, as well as the state’s natural resources.

Belknap and Collum say the doctorate program, which focuses on “understanding human society and culture in cross-cultural perspective and their pivotal role in implementing successful environmental policy,” is an ideal fit for their interests.

“It is so applicable and has an interdisciplinary framework,” says Collum. “I can look at issues holistically.”

Collum favors a multifaceted approach. She double-majored in anthropology and environmental studies at Western Michigan University, and earned her master’s in forest resources at UMaine.

Belknap agrees. He earned his undergraduate degree in anthropology and a master’s in Quaternary and climate studies, both from UMaine. “No problem is one-dimensional and no one person can solve everything,” he says.

His doctoral thesis, “Abrupt Climate Change and Maine’s Lobster Industry,” proposes collaboration between lobstermen and policymakers to better protect the state’s iconic industry, especially in the wake of abrupt environmental changes.

Experienced lobstermen possess valuable information, says Belknap. They have knowledge of the industry, concerns about both climate change and fishing regulations, and about how they’ve adapted their behavior in response to both.

Policymakers will be better informed and better positioned to craft policies customized for various situations if they routinely involve lobstermen in the regulatory process, Belknap says.

Belknap, who grew up in Damariscotta, Maine, knows his way around a lobster buoy. He learned to haul traps from his grandfather, a retired physician.

“I grew up lobstering,” Belknap says. “My wife jokes that I’m clumsy because I learned to walk on a boat, not land.”

Belknap worked as dock manager at his family’s lobster pound prior to starting his doctorate and respects lobstering as a way of life.

Abrupt climate change could threaten that way of life for the roughly 5,000 lobstermen in the state, as well as coastal communities in Maine and around the planet, he says.

Last summer, warmer water temperature in the Gulf of Maine contributed to lobsters molting a month or more earlier than usual, which resulted in a glut of crustaceans on the market. And then the price per pound plummeted.

“It’s humbling,” Belknap says of how quickly a temperature fluctuation of 1.5 to 2 degrees caused the drastic ripple effect. Another sudden change in temperature might have the opposite effect on the lobster population, he says.

Belknap doesn’t have to look far in space or time to see examples of that.

In September 1999, huge numbers of lobsters died within a few days in Long Island Sound. It devastated the local industry, which languished for more than a decade. Scientific reports have indicated warmer ocean water was — and remains — a culprit.

And last summer, lobsters in water off New York, Rhode Island and Connecticut were afflicted with a shell disease, with warming ocean water was again cited as a factor.

How policymakers and Maine lobstermen work together to deal with abrupt climate changes could be a model for other fisheries regionally, nationally and globally, says Belknap.

Practical application of knowledge is also important for Collum, whose doctoral dissertation will explore the impact of the declining bee population on wild blueberry growers and the growers’ ability to conserve wild pollinators.

Because many crops rely on insect pollination to produce fruits and vegetables, the global decline of bees – due to pesticides, habitat loss and disease — threatens food security and the livelihood of farmers who produce food.

The lowbush blueberries that grow in Maine are completely dependent on insect — mostly bee — pollination to produce fruit. Without bees, there are no blueberries for Sal — or anyone else.

Commercial honeybees are crucial for the intensive agriculture practiced in the U.S, says Collum. But research suggests, through conservation efforts, native bees can provide a significant amount of pollination without the cost associated with renting commercial hives, she says.

Last year, Maine blueberry growers imported 70,000 commercial honeybees to pollinate about 60,000 acres of wild blueberries, she says. The busy bees trucked to Maine generally start their trek in California, where they pollinate almonds, and make multiple work stops en route.

The cost to blueberry producers to pay for pollination has risen significantly, says Collum, bringing into question whether the practice is financially sustainable.

She’ll therefore explore the ability of farmers to integrate the use of both wild and commercial bees to pollinate crops and increase the yields.

Because Maine has more than 240 bee species — at least 40 of which pollinate blueberries, Collum says it’s a good place for farmers and researchers to collaboratively figure out the best practices to protect, promote and utilize wild, native bees to pollinate crops.

Collum will explore obstacles that growers in Maine and Canada have to increasing their use of wild bees to pollinate lowbush blueberries. She’ll also study what influence government policies and programs have on the way growers manage pollination of crops and how growers can adapt to changing ecological conditions.

Growers of other crops that want to transition to utilizing wild bees, where applicable, could apply the findings, she says.

Collum, who grew up in Monroe, Mich., near the border of Ohio, is used to working in the field and on the trails.

She fell in love with Maine when she was a college intern working on a trail crew at Baxter State Park in Millinocket. As a field coordinator for Rocky Mountain Youth Corps in Colorado, Collum battled the pine beetle infestation. And she worked on an ecotourism project in New Zealand, building trails, battling invasive gorse and planting native trees.

Collum urges people to know where their food comes from, to build relationships with local farmers and to support those doing their best to reduce chemical inputs. She also encourages people do what they can to protect bees, including not using pesticides around their homes and planting bee-friendly gardens.

Collum and Belknap both want to make a positive difference in the state they love and ensure that ensuing generations of lobstermen, farmers and foresters have the opportunity to make livings from the land and sea.
