Here are the places in Canada — yes, Canada — vulnerable to drought
This story is part of our series Water at Risk, which looks at some of the risks to the water supply facing parts of Canada, South Africa and the Middle East.
As conservationists and organizations around the globe mark World Water Day Thursday, some scientists are warning that Canada is not immune to water shortages and periods of drought.
These are the parts of the country most at risk: Prairie provinces All three Prairie provinces, stretching from the Rocky Mountains to the shore of Hudson Bay, are vulnerable to drought, says David Price, a scientist for Natural Resources Canada who models climate change outlooks.
A little of the moisture makes it over the mountains, but as summer temperatures rise, the risk of drought across Alberta, Saskatchewan and even Manitoba will grow, he said.
Climate change could mean even hotter summers in the region, making it more vulnerable to drought.
British Columbia has been dependent on snowpack to provide moisture through the spring and summer, but it may get more rain in winter, which would run off the land rather than melting slowly as snow does, Bonsal said.
is accustomed to seeing lots of rain, but with places like the lower Fraser region and Vancouver Island seeing less of it, they’ll have to rely more and more on water reservoirs, according to Pomeroy.
In fact, the shortage has prompted water restrictions in the province and instances of hydrological drought, which is when lakes, rivers and ground water supplies are depleted.
He predicts not much change in Yukon and N.W.T.
Climate change models vary in their predictions of whether water levels in the Great Lakes will rise or fall as weather patterns change.
