A new classification of the world's coastlines has been released to improve coastal climate change adaptation at the local, regional and national level and strengthen coordinated climate action worldwide. The classification builds on the Coastal Hazard Wheel that is a universal coastal management framework and is developed by the Coastal Hazard Wheel initiative involving Deltares, the UN Environment Programme-DHI Centre (UNEP-DHI Centre) and the UNEP Copenhagen Climate Centre, with contributions from University of Copenhagen, the Food and Agriculture Organization of the United Nations (FAO), the International Fund for Agricultural Development (IFAD) and the Novo Nordisk Foundation.
