Adaptation and Social Learning (ASL)

Research line leader: Jochen Hinkel

Goal of the process

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.

Major findings

  • 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).
