The dataset comprises the simulated loss of freshwater biodiversity intactness (expressed as MSA; scale 0-1) in lakes and rivers worldwide, as well as the simulated concentration of cyanobacteria (harmful algal blooms) in lakes (in range classes related to the WHO standards; Chorus & Welker, 2021), due to nutrient emissions to surface water. The effects have been modelled by the model GLOBIO-Aquatic (Janse et al., 2015; Janse et al., 2023). The data are global at a 30x30 arc minutes resolution, and cover the years 1970, 2010, and 2050 for six INMS scenarios, representing different combinations of SSPs, RCPs and nitrogen policy options.

Provenance & quality
The nutrient emissions and concentrations in surface water have been modelled by the Global Nutrient Model (GNM; Beusen et al., 2022) combined with the global hydrological model PCR-GLOBWB (Sutanudjaja et al., 2018). The missions are the sum of leaching from (agricultural) land, urban emissions, aquaculture and atmospheric deposition.
Land-use and climate projections were based on the IMAGE model (Stehfest et al., 2014).
