ABSTRACT
Freshwater eutrophication, the oversupply of nutrients to an ecosystem, is one of the major environmental challenges around the world. By combining systems dynamic, empirical and expert judgment models into a single object-oriented Bayesian network, we aim to assess trade-offs in ecological, social and economic values from improving lake ecological condition through nutrient abatement measures in South-Eastern Norway. We find the integrated systems model is a useful tool for determining where additional data would be most useful, but that uncertainty limits its application to EU policy on eutrophication control.
