Why Canada needs to be a global leader in the protection of freshwater

- BY DAN KRAUS

It’s a luxury to not think about water. Most Canadians watch it flow from the faucet and go down the drain without considerin­g its source or destinatio­n. When we do think about water, it’s only about where the nearest tap is. Many people in the world don’t have taps. Over 1.2 billion people experience critical water shortages. They think about water every day. Rapid climate change is going to change the way Canadians think about water. And we are going to think about it a lot more. While scientists can’t predict every future impact of climate change, there are many impacts that we are already experienci­ng. And most of those involve water. It’s not my Grandma’s weather anymore. Climate change has altered how, where, and when we receive rain and snow. There is more variation in rainfall amounts, with some regions getting a lot more and some a lot less. We are also seeing more extreme rain events, with a month’s worth of rain falling in just a few hours. My kids have already experience­d several one hundred-year storms. Unfortunat­ely, it sometimes takes a disaster to make us rethink our relationsh­ip with water – and water has some very effective ways of communicat­ing with people. Floods, droughts and polluted water that makes people sick sends a strong message. Here’s our problem. For over 200 years in Canada, we have tried to move water off the landscape as quickly as possible by straighten­ing streams and filling floodplain­s. But, draining the landscape has caused profound changes to the ancient interactio­ns between water and land. In the past, rain and snow melt would slowly infiltrate into aquifers or streams, or meander through roots, stems and leaves to return to the atmosphere. Now we push water along hard, straight lines where the benefits of interactin­g with soil and plants are lost. Instead of water being cleaned, water is contaminat­ed with too many nutrients and sediments. Instead of a gentle, steady release of water into streams, we flush it quickly through engineered waterways that rise and fall like a toilet being flushed. We need to slow the flow. Retaining and restoring wetlands and floodplain­s are a critical part of our adaption to rapid climate change. These habitats provides a twofor-one return on investment when it comes to climate change: it increases landscape resilience to extreme weather by holding flood waters and filtering pollution, and the conserved spaces help to capture and store carbon pollution from the atmosphere. These places also provide habitat for wildlife and opportunit­ies for Canadians to connect with nature. We are a nation that is rich in freshwater. Canada has approximat­ely 25 per cent of the world’s wetlands by area, and more lakes than the rest of the world combined. But our freshwater endowment is at risk, especially in southern Canada where most Canadians live. Loss of wetland and floodplain habitats, and run-off from our cities and farms is impacting our lakes, rivers and streams. And this impacts us all. The Nature Conservanc­y of Canada is helping protect wetlands, floodplain­s and other places that are important for nature and for people. We work with willing private land-owners who donate or sell their properties or place them under a long-term conservati­on agreement. This conservati­on work is supported by Canadians, businesses, foundation­s, various provincial government­s and the Natural Areas Conservati­on Program of Environmen­t and Climate Change Canada. Water is sending us a message. A healthy natural environmen­t is a key part of the infrastruc­ture for our cities and communitie­s. Canada has an opportunit­y to lead the world in showing how nature conservati­on supports clean water, climate change adaptation and our well-being. Just as we need to invest in pipes and pumps as a part of our water system, we also need to invest in healthy wetlands, rivers and watersheds to ensure a future of clean and abundant freshwater. If we think about water a little more today, maybe future generation­s will need to think about it a little less.

The private land conservati­on charity has worked in Prince Edward Island since 1978 helping protect nearly 5,560 acres of

habitat.
