By 2050, 1,500 kilometers of dikes must be reinforced in the Netherlands. Our country is vulnerable now that sea levels are rising and the risk of extreme weather is increasing.

Residents have been waiting for compensation for years. What lessons can be learned? An urgent question in view of the major dike reinforcement task that is yet to come.
