Demonstration description - visualisation of robust adaptation strategies: Deliverable D4.3

This report presents a novel decision support methodology for climate change adaptation decisions, which is tested in demonstration cases with stakeholders. Additionally, guidelines and experiences from the use of the method are presented. Through the case-themes ToPDAd has produced several specific assessment tools. Together, these models provide decision makers with a flexible, new toolset to support their adaptation policies and business choices. To demonstrate the potential of the toolset to inform decisions, ToPDAd developed two demonstration cases. The first demonstration case was presented at the ECCA conference in Copenhagen in May 2015 and the second is presented in the final workshop of ToPDAd project in Brussels in October 2015. The themes that will be demonstrated are, first, power sector adaptability in Northern Europe, and secondly, effects of drought on French electricity supply. Both case-themes are described in this deliverable. The goal of the demonstration is to 1) demonstrate the developed Strategy Robustness Visualisation Method (SRVM) and test it, 2) to bring the important climate change adaptation issues under discussion and support the case theme related decision-making and 3) to demonstrate the relevance of the modelling results in a simulated real life decision environment. The demonstration case development started at the beginning of 2014 and the second demonstration case is to be presented and reported in October 2015. The demonstration utilises SRVM which combines two decision support methodologies, namely Multi-Criteria Decision Analysis (MCDA) and Robust Decision-Making (RDM). By structuring the decision context, defining the adaptation strategies and decision criteria, and making performance of the alternatives and valuations explicit, the approach gives participants in the workshops a clear picture of which adaptation strategies are found robust and important. The approach can be used instead or as a complement to other decision support approaches such as cost-benefit analysis (CBA).
