Global change impacts

Model characteristics

  • Model name: MARINA-Nutrients
  • Version: Global-2.0
  • Application: Global
  • Scales: sub-basins and annual
  • Period: 2010-2050
  • Pollutants: dissolved inorganic (DIN) and organic (DON) nitrogen (N)
  • Sources: point (sewage) and diffuse (agriculture, natural areas)
  • Main inputs: agricultural activities, sewage systems, land use, hydrology
  • Main outputs: river export of DIN, and DON by source and sub-basin

Model outputs (example)

Figure 2: Changes in river export of total dissolved nitrogen between 2010 and 2050 according to a scenario assuming low policy ambitions in agriculture, high economic development and a lot of global warming (the combination of Shared Socio-economic Pathway 5 and Representative concentrative pathway 8.5). The scenario is developed in the INMS project and implemented to the MARINA-Nutrients model (Maryna Strokal, Mengru Wang, et al. under development).
