Organisational Structure

The Trilateral Wadden Sea Cooperation comprises of two levels of decision making, the Council of Ministers and the Wadden Sea Board.

The Council of Ministers

The Trilateral Wadden Sea Governmental Council gathers the ministers responsible for Wadden Sea affairs from the three countries every three years. At the conference they discuss Wadden Sea matters, and provide political leadership, harmonisation and decision-making between the three governments.

The Wadden Sea Governmental Conferences 

The Council meetings are held within the context of the Wadden Sea Conferences. The Conferences are a forum for stakeholders from the whole Wadden Sea Region aimed to inform policy-making and the Cooperation in its work.

The Conference

The signing of the joint Ministerial Council Declaration by Parliamentary State Secretary Ursula Heinen-Esser of the Federal Ministry for the Environment, Germany, chair of the Conference; Karen Ellemann, Minister of Environment, Denmark and Gerda Verburg, Minister of Agriculture, Nature and Food Quality, the Netherlands concluded a very successful and productive Wadden Sea Conference on the Wadden island of Sylt on 18 March 2010. The Conference was the 11th Trilateral Governmental Conference in the framework of the Dutch-German-Danish cooperation on the protection of the Wadden Sea, the world’s largest tidal barrier island system, since the first Conference in The Hague in 1978.

A revised Wadden Sea Plan was adopted. The 2010 Wadden Sea Plan updates the trilateral policies and management since the first Wadden Sea Plan was adopted at the 8th Conference in Stade in 1997. The Wadden Sea Plan constitutes the common framework for the protection and sustainable management of the Wadden Sea as an ecological entity. It is also the common management plan for the Wadden Sea World Heritage Site.

In addition to agreements to enhance the international cooperation to protect the migratory birds, for which the Wadden Sea is a key site, climate, sea level rise, coastal protection and alien species were high up on the minister’s agenda. Climate change and its consequences such as enhanced sea level rise, increased temperatures, and increasing sediment deficits will have impacts on the ecology and landscape of the Wadden Sea and may affect the safety of the inhabitants. It was agreed that there is a further need to strengthen the natural processes of the Wadden Sea in order to cope with such changes and to further cooperate in developing common strategies and enhancing the knowledge. For invasive species, which is an issue of concern for all parts of the Wadden Sea, a common approach will also be developed in the coming period.

Shipping safety was again on the agenda. It remains an issue which is of great concern for the region since an accident can have potentially enormous impact, ecologically and economically. It is of the highest priority that safety is kept on a high level and that everything is done to prevent accidents. The ministers agreed to a number of actions in this field including to continue to raise the awareness of the significance of the Wadden Sea amongst the maritime sector.

A highlight of the Conference was the signing of the 2010 Joint Declaration on the Protection of the Wadden Sea in a formal signing ceremony at the Kurhaus in Westerland. The 2010 Joint Declaration replaces the Joint Declaration, signed at the 1982 Wadden Sea Conference in Copenhagen, which had become progressively outdated. It will not alter the spirit or legal status of the Cooperation. This will remain a formal (but not legally binding) Cooperation between the governments of the three countries. In conjunction with the signing of the 2010 Joint Declaration new governance structures will be launched and replace the existing structures. The Trilateral Wadden Sea Board is the governing body of the Cooperation. Peter Ilsøe, Denmark, was appointed by the ministers as the first chairman of the Board.

The Sylt Conference introduced a new element into the Wadden Sea Conference. During the open session of the Conference an interactive discussion with the ministers, stakeholders and guests on “A Vision for the Wadden Sea - Steps to Achievement” was held. The overall objective for this session was to encourage all participants that they have a part to play in achieving the vision for the Wadden Sea. The session was moderated by Dr. Andy Brown who had earlier evaluated the Cooperation and had gained a considerable knowledge of the Cooperation. This session was much appreciated by the participants because it was felt that this was a central function of the Conferences: To obtain the good ideas and commitment of key stakeholders for the protection of the Wadden Sea, and a fruitful continuation of the Wadden Sea Cooperation.

The Sylt Conference was a milestone in the Wadden Sea Cooperation. One of the most productive periods of the cooperation was concluded with a new foundation for the Cooperation and new and pioneering future objectives.

The chair of the Cooperation has been transferred to Denmark for the next three-year period until 2013.

The 10th Trilateral Governmental Conference on the Protection of the Wadden Sea was held on the Dutch Wadden Sea island of Schiermonnikoog on 2-3 November 2005 under the chairmanship of the Dutch Minister for Agriculture, Nature and Food Quality, Cees Veerman. The German and the Danish governments were represented by Parliamentary State Secretary Simone Probst and Deputy Director General Anne-Marie Rasmussen.

The conference made the start with the actual nomination of a major part of the Wadden Sea as World Heritage Site. After the preceding consultations, Germany and The Netherlands will now make a start with the nomination procedure.

A further issue discussed at the meeting was the report of the Wadden Sea Forum installed at the previous conference in Esbjerg in 2001 under the chair of the Queen’s Commissioner of Fryslan Ed Nijpels. The report of the Wadden Sea Forum “Breaking the Ice” was welcomed by the conference and it was decided to continue the work of the Forum in the next period under the chairmanship of the chairman of county council of Ditmarschen, Jürgen Klimant. A primary task of the Forum will be to implement the action plan which it has drawn up on the basis of the strategy encompassed in “Breaking the Ice”.

A key element in the work of the cooperation in the next period is the further development of the Wadden Sea Plan into a management plan in the sense of the Habitats Directive and other directives. This is wholly in line with the intentions of the Joint Declaration 1982 which remains the basis for the cooperation. European Union legislation constitutes the overall main framework for the cooperation and the further development of the Wadden Sea Plan will ensure that this will be carried out in a coordinated way.

Another issue discussed was shipping safety. A package of measures was adopted and agreement was reached to focus on a number of areas in the forthcoming period, such as
emergency towing and pollution response. The International Wadden Sea School will be continued until the next conference. The IWSS was launched on the occasion of the 25 year cooperation in 2003 and has been a successful project to link schools and students from the area for a future sustainable conservation of the Wadden Sea as a shared area.
