This paper analyzes barriers and opportunities for effective adaptation planning in cities. In particular we focus on the preparation and adoption of adaptation strategies and action plans by urban planners. To guide the discussion we develop a two-tier framework of variables influencing decision-making which is based on bounded rationality. We argue that whether or not urban planners take action to foster adaptation to climate change depends on three first-tier variables: information incentives and resources. In addition we point out that each of these variables may itself be a function of a set of underlying second-tier variables including the natural and socio-economic environment actor-specific characteristics of the decision-maker and the institutional environment. Within this framework we specify barriers and opportunities for effective adaptation planning as hampering or promoting characteristics of these first- and second-tier variables. We apply and test the framework within the context of four case studies carried out in Lima (Peru) Santiago (Chile) Berlin and Sangerhausen (both Germany). -- Climate change adaptation ; urban planning ; barriers |
