A walk: The dikes of the future

Monday 8 May 2023, 9:30 am - 12 pm
A Radboud Gesture

Due to rising sea levels, more frequent extreme rainfall and drier summers, more and more will be asked of our dikes in the future. In the next thirty years, 1,500 kilometers of dikes will have to be reinforced in the Netherlands alone. We currently reinforce dikes mainly by making them higher or wider with extra soil. But researchers Nils van Rooijen and Hans de Kroon think that it can also be done more efficiently. If we allow more flowers and herbs to grow on our dikes, this will bring many benefits. Not only do dikes become stronger due to deeper rooting, insects also benefit from greater plant diversity. And what's more, the blooming dikes look beautiful. During this walk, Hans de Kroon and Nils van Rooijen take you up the dike and show you what grows and blooms. They also will tell you about the Future Dikes project, a project that investigates how we can strengthen Dutch dikes with a species-rich grass covering. 

Starting point: De Bastei, Lange baan 4
