It is an age old problem but one that has been getting worse with global warming.
Polar bears need sea ice to hunt and survive.
Each year the polar bears of Hudson Bay get into trouble and threaten people in the small communities along the shore, as they roam the shore area waiting for ice to form.
This has led too often to a need to destroy the bears when they threaten the villages.
Since 2010, the World Wildlife Fund - Canada has been involved in a successful program to try to prevent bear-human encounters and so reduce the need to kill the bears.
David Miller, WWF-Canada president and CEO says with steadily decreasing sea ice coverage due to climate change, polar bears in the Western Hudson Bay population are spending more time on shore in summer and away from their primary food source: seals caught from the sea ice. While waiting for the ice to freeze, some scavenge food along the coast, and are attracted to communities.
This year (September - December, 2015) the community of Arviat experienced 190 encounters with polar bears with two bears threatening human life put down under Defense of Life and Property regulations. There have been 20 attacks on humans in recent years.
The bears are attracted by the smell of meat left for the Inuit dog teams, or left out for the families themselves, and of course the odors from town dumps.
Bears roaming into or near villages can be very dangerous. Up until 2010, when the WWF-Canada began its program to chase bears out, an average of 10 bears a year were being killed under DLP regulations. Since then the average is down to one a year.
The WWF has been funding patrols to detect the bears near villages and chase them away before they pose a risk.
The daily patrols in peak bear season (September - December), take particularly at night, significantly reduce conflicts. Patrol teams have a range of tools including loud detonating devices, rubber bullets, beanbags, flares and live rounds.
Persistent bears are trapped using seal meat, and then physically transported far away from the community.
"WWF is pleased to see that our ongoing partnership with the Hamlet of Arviat is continuing to pay off for both community members and the polar bears," said Miller. "We are now working to share these successes with other northern communities to expand the program."
The WWF-Canada is now expanding the successful Arviat model to new communities in the Canadian Arctic, and sharing experiences with northern communities in other parts of the polar bear's range by hosting a front-line operators' workshop on Hudson Bay in March of 2016.
Field-testing of different management and deterrence techniques is also ongoing, including waste management and devices that release loud noises to scare bears away.
