The European Commission FP7 funded MEDIATION project (Methodology for Effective Decision-making on Impacts and AdaptaTION) is looking at adaptation decision support tools, in line with its objectives to advance the analysis of impacts, vulnerability and adaptation, and to promote knowledge sharing through the MEDIATION Adaptation Platform (http://www.mediation-project.eu/platform/).
To complement the information on the Platform, a series of Technical Policy Briefing Notes have been produced on Decision Support Methods for Climate Change Adaptation. This Policy Brief (Note 5) provides a summary of Portfolio Analysis. It provides a brief synthesis of the approach, its strengths and weaknesses, the relevance for adaptation, how it considers uncertainty, and presents case study examples. It is stressed that this note only provides an overview: more detailed information is available in MEDIATION deliverables, and sources and links on the MEDIATION Adaptation Platform.
