About the Cooperation

Since 1978, the Netherlands, Germany and Denmark have cooperated to protect the Wadden Sea as an ecological entity. The Guiding Principle of the Trilateral Wadden Sea Cooperation is to “achieve, as far as possible, a natural and sustainable ecosystem in which natural processes proceed in an undisturbed way”.

The Cooperation is based on the “Joint Declaration on the Protection of the Wadden Sea”, which was first signed in 1982 and then updated in 2010. The Joint Declaration is a declaration of intent, and includes the objectives and areas of the cooperation and the institutional and financial arrangements. For over 30 years, the Cooperation has united partners from politics, nature conservation, science and administration, along with local stakeholders, who together represent an enormous store of knowledge and experience.

It is a world wide unique example of effective transboundary ecosystem-based collaboration in order to conserve a World Heritage site.

The Trilateral Wadden Sea Cooperation:

  • protects and conserves the Wadden Sea as an ecological entity through common policies and management.
  • monitors and assesses the quality of the Wadden Sea ecosystem in collaboration with national and regional authorities and scientific institutions as a basis for effective protection and management.
  • cooperates internationally with other marine sites on protection, conservation and management.
  • engages the public in the protection of the Wadden Sea through awareness-raising activities and environmental education.
  • secures the sustainable development of the Wadden Sea with respect to its natural and cultural values.

In 2012 the Communication Strategy for the Trilateral Wadden Sea Cooperation has been developed with the participation of the Cooperation stakeholders. The Communication Guidelines can be downloaded here: English, German.
