Project

GoCoase- Governing climate change adaptation at the Baltic Sea Coast

Start of Project 08/2018
-
End of Project 12/2021

In GoCoase, climate change adaptation strategies for the German Baltic Sea coast in Mecklenburg-Western Pommerania are developed and evaluated in close cooperation with decision-makers. The project provides information on how individuals and decision-makers evaluate different coastal protection measures and weigh the costs and benefits of adaptation options. GoCoase will analyse possible institutional change due to climate adaptation challenges and discuss the assessment results with decision makers. The involvement of stakeholders in coastal protection strategies will also be analysed.

Update on the project´s process

Projected design loads and adaption potentials of soft coastal protection measures were identified. Likewise, an institutional analysis was completed to describe the current state of coastal protection. Press releases regarding formal and informal decision rules in coastal protection were evaluated. A public survey representative for Germany was conducted in order to determine the benefits of different adaptation strategies to climate change on the coast in Mecklenburg-Western Pomerania. The results will be compared with the costs of the adaptation strategies in a further work step. 

Contributions from all sub-projects on the topics of climate change adaptation on the coast were published in the magazine "Meer & Küste". A webinar was co-organised at the ECCA 2021 conference (ecca21.eu) and a thematic session was approved at the EAERE 2021 conference (eaere.org).

Preliminary results of the project

The analysis of the survey data identified three groups of people with different preferences. One group (23 % of the sample) has no positive appreciation for coastal adaptation to climate change. People in this group are not willing to pay for adaptation strategies. The second group (39 % of the sample) are willing to pay for an increase in dyke height only. Whereas the third group (38 % of the sample) prefers extensive changes. People in this group would be willing to pay for wider beaches, higher dykes, more cliff protection, as well as, for example, managed realignment of dykes and dunes for the creation of new habitats for animal and plant species.
