The updated climate scenarios for the Netherlands, which were published this week in the Klimaatsignaal’21 by the KNMI – Royal Netherlands Meteorological Institute, emphasize the urgency to address sea level rise . As part of the national ‘Kennisprogramma Zeespiegelstijging’, we explored the spatial consequences of different development directions for the long-term sea level rise. The developed research-by-design maps clearly show the urgency of short term actions in order to ensure a safe and livable future.
