Inorganic Pollution, Driver of Environmental Change: eDrivers Project for the St. Lawrence System

The data used to characterize inorganic pollution come from the global cumulative impacts assessment on habitats and available on the NCEAS online data repository.

Inorganic pollution was modeled using impervious surface area (i.e. artificial surfaces such as paved roads) under the assumption that most of this pollution source comes from urban runoff. Inorganic pollution originating from point-sources or in areas lacking paved roads is therefore not captured by this layer. The data obtained was aggregated at the watershed scale.

It is possible to consult the scientific report of the eDrivers project: Characterizing Exposure to and Sharing Knowledge of Drivers of Environmental Change in the St. Lawrence System in Canada and the additional data. It is possible to consult the application eDrivers.
