Important results from the project
The project has achieved its objective and contributed to increased knowledge and experience to improve Swedish competitiveness in the planning and management of nature-based protective dikes. This has led to increased resilience in coastal settlements. By building a prototype dike with different vegetation surfaces, the method has been validated, with guidelines and guidance developed. The project has also promoted cross-sector collaboration between academia, business, and the public sector.
Expected long term effects
The results are expected to influence how future protective dikes in Sweden are built, which should increase biodiversity without compromising flood protection. The cross-sector collaboration enables the dissemination of project results, which strengthens society´s ability to build flood-proof protective dikes for low-lying coastal settlements. The project shows how climate adaptation measures can be combined with efforts for biodiversity, which is expected to inspire many actors.
Approach and implementation
The project was divided into the following phases: Planning: Design and siting of the prototype embankment, Q1 2022 Implementation: Construction of prototype embankment, Q2-Q3 2022 Follow-up: Inventory and measurement of prototype swell, Q3 2022-Q3 2023 Analysis: Analysis of prototype embankment, Q-Q4 2023 The project followed the schedule, but it became clear that one growing season for evaluating the re-establishment of vegetation was too short, so an extension of 1 year was granted.
