After a wildfire tore through the forest around Kakisa, N.W.T., in 2014, Lloyd Chicot began noticing changes in the lake: the pickerel grew fatter, and the pelicans moved in. Chicot, the chief of Ka'a'gee Tu First Nation, attributes the change partly to climate change and partly to runoff from the fire, which brought nutrients and debris into the lake. "Right after the fire, there was a lot of burnt driftwood and that kind of stuff," he recalled.
On a feedlot in central Alberta, nearly 100 kilometres northeast of Calgary, researchers gathered to watch as floating islands were launched onto a pond created by runoff water. To people driving past on a nearby dirt road, it might not look like much. But the islands are the result of years of research and testing that could help the feedlot business recycle wastewater to the point where it could be used on crops or for cattle. And it could go beyond just that.
Canada's environment minister is denying the Saskatchewan government's allegations that federal scientists purposely trespassed on private farmland and were testing water samples for nitrates or nutrients related to farm runoff. On Sunday, Saskatchewan Minister Responsible for the Water Security Agency Jeremy Cockrill posted a public letter to federal Minister for Environment and Climate Change Canada Steven Guilbeault.
Maitland Conservation (MC), formerly Maitland Valley Conservation Authority (MCVA), has been monitoring two agricultural sub-watersheds to address water quality concerns and the effects of farming practices on local water. Ben Van Dieten, Agricultural Stewardship Technician, and Chris Van Esbroeck, Stewardship Services Coordinator of MC, presented their findings to date on these projects, in terms of how and when sediment and nutrients leave the landscape, and the practices they promote to reduce these losses.
A new University of Saskatchewan smartphone app will help farmers and communities identify hotspots of nutrient contamination in freshwaters and possibly predict where algae blooms — slimy, plant-like green organisms that hinder water quality — are likely to grow. “Tracking how and where agricultural nutrients, which help crops grow, may be washed away with rainfalls and snowmelt is a major concern for both researchers and the public, and that’s where our app comes in,” said Environment and Climate Change Canada scientist Diogo Costa.
