Case 20 - Ecosystem Services in Coastal management: Case Wadden Sea the Netherlands
|Please read the OpenNESS case study booklet 'Ecosystem services in operation' for the final outcomes of the cases. More detailed information about the cases and the tools and methods used can be found on Oppla: www.oppla.eu|
The Dutch Wadden Sea has a World Heritage status and is part of a large Natura 2000 network. In this area economic development of the harbours fringing the Wadden Sea is encouraged by government and local politicians to enhance their international competitiveness. The biggest policy challenge for the Wadden Sea, therefore, is to enhance economic development while maintaining ecological quality and integrity of the area. This case study zooms in on maintenance dredging in the marina of the Wadden Isle Schiermonnikoog “Jachthaven Schiermonnikoog”. The objective of this case study is how to manage dredging sludge within a Natura 2000 area. Whereas, at first glance depositing sludge may negatively impact Natura 2000 goals, reuse may also benefit ecosystem services. In the case study an inventory is made on the influence of different scenarios of depositing dredging material on the ecosystem services of the area.
The aim of this case is to explore how assessment of ecosystem services may change the appreciation of management scenarios. Current management of the marina has been based without including Ecosystem Services. One of the interesting findings of this study, taking an Ecosystem Services approach, is that although dredging of the marina can be viewed as negatively impacting the Natura 2000 goals, refraining from dredging and thus blocking the marina for recreational vessels results in more of these vessels getting stranded on the mudflats at low tide, and thus more disturbance for waders, species whose protection is aimed for by Natura 2000.
The case study contact Chris Klok IMARES is involved in TEEB-NL in which this case acts as an example on how biodiversity and ecosystem services contribute to economy and human wellbeing.
