CAP-AUX-MEULES, CANADA (AFP) – In the Gulf of Saint Lawrence, on the small Magdalen islands, foot paths are caving in, cliffs are receding and the sand dunes are disappearing, leaving homes vulnerable to the lashing waves.
The archipelago, part of Quebec province in eastern Canada, is in a race against time – and the elements – to survive global warming. Residents are feeling the effects of climate change on a daily basis.
“The Magdalen islands are in the front row when it comes to the changes taking place. We are miniscule faced with the immensity of it all,” said Mayka Thibodeau from CERMIM, a research centre focused on sustainable development.
The changes seem to be coming fast and furious, leaving the roughly 13,000 residents reeling, as they realise their island home will need to adapt quickly and radically in the decades to come if it is to survive.
The islands’ picturesque shores have already been eroded, receding by an average of half a metre a year, according to a study by the University of Quebec at Rimouski (UQAR).
It’s a figure that concerns Diane Saint-Jean and her partner – they live on the coast and worry the next big storm could sweep their home into the water.
“We were rather naive, we were sure there would be a solution. But nature proved us wrong,” said Saint-Jean, her voice shaky as she stares at the nearby cliffs, which are slowly disappearing.
The two women live in La Martinique, a slim band of territory that links the archipelago’s two main islands.
They have spent thousands of dollars to reinforce the cliff at the foot of their yard, but in September 2022, Hurricane Fiona struck with brute force, quickly washing away the giant rocks meant to protect their property.
“We woke up one morning and realised we’d thrown away our money. But what can we do?” rued Saint-Jean, a retired nurse.
Erosion is a bit of a sensitive topic for most residents on the Magdalen islands, which were first populated in the 18th Century and are located more than five hours by boat from continental Canada.
Everyone here remembers spots that are now gone – especially houses that had to be moved because of the risk of flooding.
The situation is a headache for local authorities, who must invest millions of dollars for emergency work.
In Cap-aux-Meules, in the center of town, part of the pedestrian walkway collapsed in 2018, leaving the hospital, a retirement home and a cemetery in the direct path of dangerous waves.
Last year, local authorities built a huge gravel beach, using 143,000 tonnes of stones along an 800-metre stretch to raise the shoreline. It was not the first time the tactic had been used.
“Solutions exist but they are extremely expensive and these projects have to be maintained.
So each time we intervene, it’s a tax burden for the future,” explained Jasmine Solomon, who monitors erosion for the local government.
“We likely won’t be able to protect everything. There are spots that are going to need to change, that’s for sure.”
In recent years, extreme weather events have become more frequent and more devastating as a result of climate change.
The Magdalen islands are notably losing one of their most important defences in winter: ice.
It has always served as a sort of shield, but without it the coasts are completely exposed when rough storms hit.
With each cycle of freezing and thawing, the red sandstone cliffs crumble more easily.
“One storm can erase a dune, a cliff, or even open up a breach” in the coastline, said director of local environmental organisation Attention Fragiles Marie-Eve Giroux.
In addition to raising awareness about ecological issues in local schools, her group works on dune restoration, especially by replanting them with beachgrass, which helps keep the sand in place as its roots create a natural net.
Many times, the dunes are the shoreline’s only defence against the waves.
The islands are in danger of being lost to rising waters, a fate shared by other low-lying areas around the world. They are also gradually sinking.
“We must look at all realistic scenarios and not bury our heads in the sand,” said Thibodeau.
“We don’t just want to endure what is to come. We want to be part of the solution.”
She explains the many projects undertaken by CERMIM to restore the beaches including the use of mollusk shells to make concrete. The idea is to turn the islands into a sort of living laboratory in the global battle against climate change.
