Crop production impacts

Model characteristics

  • Model name: MARINA-Plastics
  • Version: China-1.0
  • Application: China
  • Scales: sub-basins and annual
  • Period: 2010-2100
  • Pollutants: macro- (>5mm) and microplastics (<5mm)
  • Sources: crop production (mulching, greenhouse plastics), point sources (sewage), diffuse sources (mismanaged solid waste)
  • Main inputs: application rates of plastics for mulching and greenhouses, residue rates of plastics in soils, population connected to sewage systems, removal efficiencies, hydrology
  • Main outputs: inputs of macro- and microplastics to rivers by source and sub-basin
