This article describes and analyzes the reintroduction of the “wide green dike” in the Netherlands. It is a noteworthy example of implementation of an innovation in long-term strategic delta planning. The Dutch Delta Program was central herein. Pursuing its ambition to make the Netherlands climate-proof, the Delta Program invited a diverse set of actors to participate in developing a long-term adaptation plan, and also to propose innovative short-term measures to help realize that plan. The wide green dike was actively promoted by a local water board, with involvement of scientists and nature conservation organizations. A stepwise participatory process resulted in national-level recognition of the potential of the wide green dike, particularly due to its “green” and “adaptability” characteristics. Alignment of flood protection and climate adaptation goals with nature conservation objectives, as well as collaboration with new actors, were all crucial in the reintroduction of this innovation.
