Gain an in-depth understanding of the drivers, social processes and formal & informal institutions that enable or hinder climate adaptation and social transformations, and co-develop, together with stakeholders, desirable, efficient and robust adaptation strategies in face of deep uncertainty about climate change.
Climate change adaptation is a continuous learning process involving actors and organizations at all levels. In many cases this involves overcoming social dilemmas through collective action (Bisaro and Hinkel 2016).
Despite the large uncertainty about sea-level rise, long-term decisions can be improved by applying decision analytical methods that take into account future learning about sea-level rise (e.g. real-option analysis, adaptation pathway analysis) (Hinkel et al. 2019).
Adapting to 21st century sea-level rise is, for most places, technically feasible, and for about 90% of the coastal population this is much cheaper than retreating from the coast. However, for the remaining 10%, comprising rural and poorer areas, adaptation costs are very high relative to local GDP and cannot be met without national transfers and international support (Lincke and Hinkel 2018, 2021).
Governing coastal adaptation is a political process that raises distributive conflicts. Powerful actors can capture these processes following their political and/or economic interests, potentially undermining adaptation outcomes (Gussmann and Hinkel 2021).
