Staff Research Highlight - Comparative Valuation of Three Ecosystem Services in a Canadian Watershed Using Global, Regional, and Local Unit Values

Staff Research Highlight - Comparative Valuation of Three Ecosystem Services in a Canadian Watershed Using Global, Regional, and Local Unit Values

This new study, authored by Dr. Tariq Aziz, aims to compare ecosystem services values derived from three different sources: locally derived unit values specific to the Grand River Watershed, unit values from a regional database, and unit values compiled in the global Ecosystem Services Valuation Database (ESVD).

HGS RESEARCH HIGHLIGHT – Effect of topographic slope on the export of nitrate in humid catchments: a 3D model study

Agricultural nutrient runoff refers to the movement of excess nutrients, such as nitrogen and phosphorus, from agricultural lands into water bodies such as rivers, lakes, and oceans. While nutrients are essential for plant growth, excessive runoff can have significant impacts on both human and ecosystem health.

HGS RESEARCH HIGHLIGHT – Testing high resolution numerical models for analysis of contaminant storage and release from low permeability zones

This study by researchers at the University of Guelph and Colorado State University tests out different numerical groundwater flow and transport models to simulate contamination diffusing into and subsequently out of low permeability zones.

HGS RESEARCH HIGHLIGHT – Evaluating Domestic Well Vulnerability to Contamination From Unconventional Oil and Gas Development Sites

HGS RESEARCH HIGHLIGHT – Evaluating Domestic Well Vulnerability to Contamination From Unconventional Oil and Gas Development Sites

This study by researchers at Yale University and the Institute of Technology investigates how vulnerable groundwater wells are to contamination by the growing unconventional oil and gas development industry, which is expanding quickly and, in some cases, negatively impacting groundwater quality and posing a risk to public health by contaminating drinking water sources.

HGS RESEARCH HIGHLIGHT –  Landscape restoration after oil sands mining: conceptual design and hydrological modelling for fen reconstruction

HGS RESEARCH HIGHLIGHT – Landscape restoration after oil sands mining: conceptual design and hydrological modelling for fen reconstruction

This study by researchers at the University of Waterloo investigates whether fen peatlands could be reconstructed on post-mine sites. Oil sand extraction can be very harmful to the natural land surface and can have lasting impacts on local ecosystems. This paper focuses on the fen peatlands that cover 65% of the landscape in Fort McMurray, Alberta. Our ability to reinstate these peatlands after mining operations has not truly been tested at large scales, and there are many uncertain factors that can impact reclamation plans for these sensitive wetlands.
