Integrating Environmental Water Research Across Multi Scales and Disciplines 

Water is our most precious natural resource. All human activities, from agriculture and industrial processes to domestic uses, depend on water of sufficient quantity and quality. This is also true for natural ecosystems. In contrast to highly visible water quantity stressors, such as flash floods and prolonged droughts, changes in water quality are often more gradual and more difficult to detect, and their cumulative impacts more difficult to predict and manage. Water quality deterioration, however, poses more pervasive and chronic risks to the economy, human health and the ecological life-support systems of the planet.  

Water quality degradation is a global phenomenon. In Canada, for example, harmful and nuisance algal blooms are a persistent problem for many freshwater bodies, including the iconic Laurentian Great Lakes, while many of our First Nations communities still live under drinking water advisories. Globally, awareness is also growing that climate change adaptation must be an integral part of planning and implementing effective water management policies and practices.

    Ecohydrology Professors Philippe Van Cappellen and Fereidoun Rezanezhad are co-Investigators on two new research projects on building sustainable net-zero emissions in Canada by 2050, funded by the Government of Canada's Environmental Damages Fund through the Climate Action and Awareness Fund (CAAF).

    Philippe and Fereidoun are co-Investigators on Can-Peat: Canada's peatlands as nature-based solutions to climate

  2. Nov. 22, 2022New paper presents a global dataset on the timing and rates of increase of chlorophyll-a concentrations in northern lakes

    Lakes in cold regions are key ecosystems. However, the environmental controls on the biological productivity of these lakes – including surface temperature, ice phenology, nutrient loads, and mixing regime – are increasingly altered by climate warming and land-use changes.

  3. Oct. 12, 2022New research paper examines the impact of winter pulsed warming and snowmelt on nitrogen cycling in agricultural soils

    A research paper by ERG group member Danielle Green published in Frontiers in Environmental Science examines the effects of winter pulsed warming and snowmelt on nitrogen cycling in agricultural soils. The field-scale lysimeter experiment results show that increased winter pulsed warming and snowmelt over the non-growing season causes increased loss of nitrogen from agricultural soils as nitrous oxide emissions in silt loam soils and nitrate leaching in loamy sand soils.
