The Marker Wadden finds a good balance between traditional wisdom and technology advance. On the one hand, based on the polder model, a traditional consensus way of planning and decision-making in the Netherlands, the Marker Wadden project is created by an alliance of both public and private bodies sitting together and their opinions acknowledged. On the other hand, it boldly explores in both philosophy and technique, and a new nature has been achieved by using innovative techniques and natural processes. Marker Wadden will be of great importance in a time of climate change. Wetland design and construction can contribute to sustainable water management, improve local ecosystems, and provide greater resilience of river deltas in storms and floods.
