There is increasing evidence that artificial light at night (ALAN) alters behaviour, space usage, migration, physiology, development and reproduction in almost all groups of organisms, including plants and micro-organisms. PRW, in the context of the Trilateral Dark Sky initiative, has commissioned a review of this in cooperation with the Common Wadden Sea Secretariat and the Partnership hub.

An interview with Frank Ahlhorn. Since August 2020 I am the Managing Director of the Wadden Sea Forum (WSF), an independent multi-stakeholder forum for the trilateral Wadden Sea region.

The current mud dynamics in the Wadden Sea are strongly influenced by human activities and interventions, including dredging waterways and the use of mud for land reclamation. In this context, mud is understood to mean sediment with a grain size of less than 63 micrometers. For the trilateral Wadden Sea, a good insight into the mud balance is lacking. The Wadden Academy and Programme towards a Rich Wadden Sea (PRW) asked Deltares to start a study on this. Where does the mud come from, what happens to the mud in the Wadden Sea and what are the possible consequences of human intervention. This report Where Mud matters – Towards a Mud Balance for the Trilateral Wadden Sea
Area: Mud supply, transport and deposition provides the first mud balance for the trilateral Wadden Sea.

This is a strategy for climate adaptation on the Wadden coast that sets priorities, inspires and looks forward towards an attractive, integrated, climate-resistant future in the 21st century. We here offer a perspective on the future of the Wadden coast in the form of an adaptation strategy. PRW is supported in this project by Strootman Landschapsarchitecten. Several working sessions with sounding board groups and experts have provided valuable input and lively discussion. This report is the result.

A report on how manual cockle-raking may affect availability of cockles Cerastoderma edulefor oystercatchers Haematopus ostralegus in the Dutch Wadden Sea.

In January 2020 the third Total Count of the East Atlantic Flyway was organized. All waterbirds wintering along the coast from Norway till South Africa were counted. This collaboration and simultaneous count is of upmost importance to gain insight into the trends of the various bird populations using the Flyway. The now published basic report gives a first overview of the bird numbers counted in 32 countries along the Flyway.  (Pdf, 12 Mb)
