D1.2: Report on review of cross-sectoral impact of decisions and types of problems and contexts in which different dimensions of uncertainty play a role: An exploration of tipping points in climate policy responses
Adaptation to climate change is becoming increasingly necessary, with potentially severe climate-induced changes still ahead. Of key relevance for decision-making is the potential existence of points in time where the decision situation changes from one type to another because an impact threshold is exceeded. Such a change in the decision situation is, for instance, when the decision shifts from being the concern of one actor or agency to multiple actors at multiple scales. We call these points adaptation crossroads. Their existence has important implications for adaptation decision support because they are where strategic and transformational adaptation decisions will have to be considered. We present three cases to explore adaptation crossroads and look at the implications for scientific decision support. We draw some first conclusions, present a typology of adaptation crossroads, and lay groundwork for further inquiries into this area.
