Water as Leverage for Climate Adaptation: Wadden Sea Region Terschelling Call for Action Harmonising the different objectives through a natureinclusive vision 1. In need of a long term vision A long term vision on the village, harbour and transport of people and goods is needed. The regional vision is needed for the further development and densification of West-Terschelling wherein the water issues are linked to the challenge of providing affordable starter homes. There are plans to build 135 homes with extra attention for affordable homes for starters because the housing prices on the island are increasing. This new densification should be developed in an integral way, which may involve disconnecting the rainwater discharge, providing maximum rainwater collection, applying sufficient infiltration or adapting to sea level rise. Although high water protection is the most urgent issue, we also need to think about selfsufficiency in freshwater, building materials or renewable energy. There is a need for a regional vision that uses the water problematics as a leverage for the different challenges of Terschelling. Important actors that should be included are the municipality, the province, ‘Rijkwaterstaat’ and SOS- Terschelling. SOS-Terschelling is a local organisation forming the voice of many residents. Since the design of the harbourfront has a major impact on the experience of the Wadden Sea for the residents and the visitors, it is crucial that they are sufficiently involved and can participate in the redesign. 2. A future proof design for the harbour Terschelling already has a redesign of the harbourfront on the table, but the challenge of providing flood protection that is viable in the long term is not adequately addressed. The project team needs to work with the existing design and propose a feasible and integrated project where a static wall is replaced by a natureinclusive process that provides longterm protection. 3. Creating solutions to work on climate adaptation in Natura2000 areas Terschelling strives towards an integrated plan, including nature improvement. This can be done both on the island, in the harbour and fairways in the Wadden Sea. Working with nature based solutions needs to be a cornerstone in the approach. Nature based solutions are specifically needed to deal with the areas under the protection of Natura2000. The principle of 14 Terschelling
Setting the Scene for a Call for Action ‘nature for nature’ has already been applied elsewhere in the wadden region and means that the existing nature could be changed by another type of nature. Terschelling sees potential in using the mudflats for the protection of the harbour or by strengthening its biodiversity with the help of seaweed or seafood crops. An integral solution could possibly be found by using the artificial mudflats and using them as protective dunes by dropping sand on top of the breakwaters. These kinds of solutions require ecological, technical and juridical expertise to be implemented. To make the solutions realistic to implement and to form an example for other cities, it is also necessary to look into the financial feasibility. This situation of a town lying outside the dikes (buitendijks) occurs in 11 more locations in the Netherlands. A nature-inclusive flood protection for Terschelling could form an example for them and for many coastal towns where this problem will arise in the future. This means that the proposal must be financially feasible so that other municipalities can apply similar principles. It has already been suggested that a large artificial dike could be too expensive, making it more realistic to shift the logistical path, to make the homes floodadaptive or to even relocate the housing towards a safer area. These decisions have to be supported by a cost-benefit analysis. 4. Pilot projects and partnerships Develop four or five pilot projects which are needed and envisage the vision for the future. The pilot projects need to be integral, feasible, inclusive and scalable. It is crucial to develop pilot partnerships which have the intention and capacity to develop and implement the projects in the following phase. To do so, the case of Terschelling asks for multi-disciplinary teams consisting of experts in: • Climate proof regional planning of harbours and housing areas; • Hydromorphology and sediment movements; • Juridical regulations on Natura2000; • Nature-inclusive design; • Technical engineering; • Bankability and costs-benefits analysis; • Process facilitation (and participation).
