Neuwerk (Germany), a small tidal island in the Wadden Sea and part of ICLEI Member City Hamburg, is becoming a valuable example of how remote communities can build resilience to climate change. With rising sea levels and stronger storm surges posing growing risks, the island is working closely with the City of Hamburg through the RescueME project to plan for the future.

Despite its size – just 3.3km² – Neuwerk faces complex challenges. Reaching the island depends on tides, ferry routes change yearly, and infrastructure is limited. Yet its residents are known for their adaptability and strong community ties. As Dr Katharina Greve from the Hamburg Wadden Sea National Park Authority explains, “People living on small islands are already very resilient – but they still need support.”

To guide that support, Hamburg and local partners are using "serious games" developed by Fraunhofer. This interactive planning tool brings stakeholders together to explore scenarios, test ideas, and uncover gaps in preparedness – from emergency response to population ageing.

Neuwerk is also recognised as a cultural landscape: shaped over centuries by both natural forces and human adaptation. Features like the island’s protective dike, its traditional horse-cart transport, and the iconic 700-year-old watchtower – now set to be restored – are part of its living heritage.

By integrating local knowledge and long-term thinking, Hamburg is helping ensure that life on Neuwerk remains viable – and that lessons from the island inform wider climate adaptation efforts.
