The aim of the WADWAD project is to develop an innovative, climate-resilient and ecosystem-based action plan for the Wadden Sea's land-sea transition zones. This trilateral action plan will be designed on the basis of knowledge from various scientific disciplines, the expertise of decision-makers from politics, administration and management and the opinions of local coastal residents. The focus here is on creating knowledge about the regional effects of the complex interrelationships between sediment dynamics, climate change and ecosystem loss. This will make it possible to develop ecosystem-based adaptation scenarios that offer concrete, local solutions to the challenges of sea level rise and climate change.
