Data collection is undertaken on a regular basis and the lessons learned from these practices are used to develop a national vulnerability and adaptation assessment (Government of Norway, 2010, Government of Norway, 2011, GIZ 2013). The evaluation of a specific project may be subject to hindrances. Specifically, the evaluators need to construct a control group for the comparative evaluations of a given project. The ideal benchmark is the fictitious counterfactual scenario, which describes what would have happened if the specific project had not been put in place.
