The Great Lakes are the world’s largest freshwater system, covering about 3% of Canada’s surface area. But, they’re responsible for 35% of Canada’s gross domestic product. Many factors currently threaten the Great Lakes, including climate change, and growing populations. These threats could also lead to economic consequences for the region.
The research team applied a new model to identify how climate change scenarios could impact water security and the economy in the Great Lakes. Ultimately, their findings can be used to minimize impacts of disruptions in water supply on the economy of the Great Lakes.Garcia-Hernandez, J.A., and Brouwer, R. (2020).
