Diffuse total phosphorus inputs into waters

Total phosphorus inputs into waters have been analysed by the MODIFFUS material flux model for all the diffuse input sources (arable land, permanent grassland, forest, glaciers, urban green space, etc.) and all diffuse input pathways (soil erosion, leaching, run-off, drainage, atmospheric deposition, etc.). The map shows the total input for each land use category in the hectare grid, based on the 2013/18 land use statistics. Average climatic conditions are used and the reference year is 2020.

These modelled values are not equivalent to values measured in the waters because they do not take into account the conversion and deposition processes both on land and in the waters themselves. The results are interpretable for hydrological or administrative units over 50km2 in size, but not for single pixels.
