Pollution due to livestock production

Model characteristics

  • Model name: MARINA-Multi
  • Version: Global-2.0 (published as MARINA-Global-L in Li et al., 2022)
  • Application: Global
  • Scales: sub-basins and annual
  • Period: 2010-2100
  • Pollutants: nitrogen, phosphorus,
  • Sources: diffuse sources (manure application on land) and point sources (direct discharges of manure to rivers) from livestock production
  • Main inputs: livestock numbers, manure excretion rates, land use, crop production, hydrology
  • Main outputs: inputs of multiple pollutants to rivers by source and sub-basin
