Subproject 3 is developing environmental extensions to the PRINCE framework in order to develop indicators for pressures linked to agricultural and other land-based production systems (especially timber). Specifically, it looks at:

  • how changes in the way land is used affect overall greenhouse gas emissions, primarily the carbon emissions resulting from forests being replaced by agricultural land;
  • environmental pressures linked to the release of nutrients associated with land-based production – particularly nitrogen and phosphorus from fertilizers and manure – which can cause eutrophication. Other sources of these substances, including wastewater and emissions to air, will also be counted;
  • release of greenhouse gases other than CO2 from livestock rearing (e.g. methane from enteric fermentation and manure handling, along with nitrous oxide from manure handling and fertilized agricultural soils).

The team

The Subproject 3 team is led by Christel Cederberg of Chalmers University of Technology.

Key activities

  • All three strands of research will include gathering, assessing and refining available data sets; compiling them into environmental extension databases compatible with the PRINCE framework defined in Subproject 2; and reporting on data refinements, gaps and additions.

  • Developing an indicator for emissions effects of land-use change will involve calculating carbon emissions using remote sensing data on land-use change and carbon stocks in cleared vegetation, using methodologies recently developed by consortium members.

  • Developing eutrophying footprints is a relatively recent phenomenon, and most attempts have been linked to food production. This work will involve determining the most appropriate measures for nitrogen and phosphorus for consumption-based modeling, as well as integrating this data with on other sources of eutrophying chemicals.

Outputs

  • Data tables on all three sets of emissions

  • Scientific paper documenting the agricultural system data improvements and integration within a consumption-based accounting framework, with preliminary results for Sweden

  • Summary report on the work package
