Coastal regions are among the most climate‑sensitive areas on Earth. Around 41% of the global population and 60% of megacities are located in coastal zones. Climate change is expected to raise mean sea levels and intensify extreme events such as storm surges. Because many natural habitats lie close to the coast, these ecosystems face mounting risks from both human activities and natural forces — including pollution, habitat destruction, and climate change itself.

Rising seas, shifting storm patterns, and prolonged droughts accelerate erosion by disrupting the natural flow of sediment. This erosion undermines ecosystems that provide critical services: reducing shoreline loss, filtering water, and protecting communities from floods. When these systems collapse, the consequences cascade, destabilising coastal regions, threatening livelihoods, and placing tourism, industry, and wildlife at particular risk.

Solutions for Restoring Coasts: Efforts to restore Europe’s coasts are gaining momentum. In 2025, WWF released a report outlining “10 key principles for effective marine and coastal restoration”, designed to ensure that restoration is lasting, science‑based, and aligned with the EU’s Nature Restoration Law.
Research using advanced computer models has shown that raising flood barriers (dykes) in priority coastal areas could reduce damages by more than 80% across one‑quarter to one‑third of Europe’s coastline. This evidence underscores that focusing resources on high‑value regions is the most effective and economically sound strategy for defending against future floods.
Europe has also invested in large‑scale initiatives such as the CLIMAREST project, which addresses coastal vulnerability by combining protection with ecological restoration. These projects highlight the importance of integrating engineering solutions with ecosystem‑based approaches to build resilience.

The Way Forward: Coastal restoration in Europe must go beyond piecemeal interventions. It requires:
– Radical transparency in restoration projects, ensuring they are science‑driven rather than symbolic.
– Integrated strategies that combine natural solutions (wetlands, dunes, seagrass meadows) with engineered defenses.
– Community engagement, recognising that coastal populations are both the most vulnerable and the most critical actors in sustaining change.
By restoring ecosystems and reinforcing defenses, Europe can safeguard its coasts against climate extremes while preserving the habitats and livelihoods that depend on them.
