Fine-scale anthropogenic nutrient input data for 8 watersheds along the Saint Lawrence River (1981, 2021)

We quantified Net Anthropogenic Nitrogen and Phosphorus Inputs (NANI-NAPI) at two scales (the finest one, the municipality, and a coarser one, the county) for all municipalities and counties of 8 watersheds in Québec, Canada, for 1981 and 2021.

The datasets here report 1) watershed NANI and NAPI values accounted from both scales for 1981 and 2021, 2) municipality-scale NANI values for each municipality in the 8 watersheds, and 3) certain components of the municipality-scale NANI for all municipalities in the Yamaska watershed.
