The demonstration cases: where cost-benefit models and decision makers’ preferences meet
With the help of sector specific and macro-economic models, combined with climate scenarios, ToPDAd assesses the cost and benefits of different strategies to adapt to climate change. In addition to cost factors, decision makers have to take into account many other factors too, when they decide on adaptation strategies. How do they balance different needs and tackle the uncertainty in adaptation planning?
It was also presented at a demonstration workshop at the ECCA conference in Copenhagen. In the workshop participants are asked to assess the performance of different strategies from multiple perspectives and in two extreme socio-economic scenarios. 
By structuring the decision context, defining the adaptation strategies and decision criteria, and making performance of the alternatives and valuations explicit, the approach gives a clear picture of which adaptation strategies are found robust and important. Later this year another demonstration of the method will be organised.
The approach can be used instead or as a complement to other decision support approaches such as cost-benefit analysis (CBA).
