Industrial, agricultural, and natural pollution pose a critical problem for the Prairie provinces of Canada, with significant environmental and health concerns. This study addresses a critical knowledge gap by assessing the cumulative impacts of pollutants in the Prairie region, which hosts 40 % of the Canada's indigenous population, often living near these pollution sources. By innovatively integrating Sentinel-5P satellite data, Google Earth Engine, ArcGIS, and Python, we show the trends in CO, NO₂, HCHO, SO₂, and aerosols from 2019 to 2023 at high resolution for the entire region, which sheds new light on the dynamics that operate beyond conventional air quality monitoring.

Anthropogenic inputs of nitrogen and phosphorus to lakes have increased worldwide, causing phytoplankton chlorophyll concentrations to increase at many sites, with negative implications for biodiversity and human usage of lake resources. However, the conversion of nutrients to chlorophyll varies among lakes, hindering effective management actions to improve water quality. Here, using a rich global dataset, we explore how the relationship between chlorophyll-a (Chla) and nitrogen and phosphorus and inferred nutrient limitation is modified by climate, catchment, hydrology and lake characteristics.
