Five years ago, a unique project was launched in the Markermeer: the construction of Marker Wadden. Using clay, silt, and sand, an archipelago of islands was created where nature can flourish. Nature filmmaker Cees van Kempen made a documentary about this example of Dutch ingenuity: Marker Wadden, a wonderful nature story. The construction of the Afsluitdijk and Houtribdijk dikes closed off the Markermeer, causing biodiversity to decline rapidly. In Marker Wadden, you can see how nature is developing rapidly on these new islands. Birds, insects, plants, and fish are appearing, and breeding birds are once again finding peace and space.
