Within the North German initiative "Norddeutsch und Nachhaltig - Mit Bildung Zukunft sichern" (NuN), the International Wadden Sea School (IWSS) has been re-certified as "Bildungspartner für Nachhaltigkeit" (educational partner for sustainable development).

The tour was conducted in the framework of the Memorandum of Understanding between South Korea and the Trilateral Wadden Sea Cooperation, that was signed in 2009 and updated in May 2023.

Upon invitation of the Common Wadden Sea Secretariat (CWSS), the Hamburg Wadden Sea National Park Authority (NPV HH) visited the Wilhelmshaven office on 8 June for personal exchange.

The Trilateral Wadden Sea Cooperation (TWSC), with the Wadden Sea Plan (2010) at its backbone, operates to conduct a shared policy and management strategy for the protection and sustainable management of the area, with the imperative of safeguarding its Outstanding Universal Value (OUV).

Since 2009, the Republic of Korea and the countries of the Trilateral Wadden Sea Cooperation have been in mutual exchange – on topics such as management, environmental education, and sustainable tourism, but also on the Wadden Sea’s experience in becoming a World Heritage Site.
