A type of scientific modelling often used by the environmental sciences and environmental policy analysis. The modelling is integrated because environmental problems do not respect the borders between academic disciplines. Integrated assessment models therefore integrate knowledge from two or more domains into a single framework; knowledge at different scales could be integrated as well. Integrated modelling is referred to as assessment because the activity aims to generate useful information for policy making, rather than to advance knowledge for knowledge's sake.
