Important deviations arediscussed and improvements are suggested.The second publication 14 describes an analysis of the importance of risk perceptivevalues among stakeholders for the management decision in a much debated sedimentremediation case in Oslo harbor Norway. Perceptive affecting factors (PAF) areidentified and items to be addressed within a successful stakeholder involvement modelare discussed.In the third paper 15 environmental impacts, not only relating to the contamination itself,but also to energy and resource use connected with the remediation effort areinvestigated. The life cycle assessment (LCA) methodology is adapted to marineconditions and the environmental footprint of different sediment capping materials forremediation of the contaminated Grenland fjord in Norway are evaluated.11
IntroductionThe fourth paper 16 describes a participatory “bottom-up” multicriteria involvementprocess (MIP) for involvement of stakeholders in contaminated sediment managementand evaluates the model for future sediment remediation in Bergen harbor, Norway. Theproposed methodology builds on the quantitative principles of multicriteria decisionanalysis, but also incorporates group interaction and learning through qualitativeparticipatory methods.Finally, in paper five 17 an integrative “top-down” decision model incorporating social,environmental and economical values in the decision by use of stochastic multicriteriaanalysis is proposed. This model incorporates the different analytical approaches likerisk analysis (RA), life cycle assessment (LCA), multicriteria analysis (MCA) andeconomic valuation methods. The model is evaluated for the Grenland fjord remediationproject.The papers are highly interconnected and respond in plural to the research question andthe sub questions as shown in Figure 2.Figure 2Structure of thesis and relation between the papers and theresearch questions12
