Overview

• Valencian authorities have greenlit over 8,000 homes in Alicante, 11,000 in Castellón and nearly 5,000 in Valencia within zones classified at high flood risk
• Greenpeace’s Destrucción a toda costa 2025 report forecasts average beach retreat of 15–26 meters and a sea-level rise of 0.20–0.27 meters by 2050 along Spain’s coast
• In the Basque Country, beaches such as Gaztetape in Getaria and Muriola in Barrika could disappear entirely by mid-century without urgent adaptation measures
• Coastal wetlands and dune systems like the Marismas del Odiel in Andalusia and the Marjal de Pego-Oliva in Valencia face extreme inundation threats as development encroaches
• A post-DANA decree has relaxed construction norms up to 200 meters from the shoreline, enabling large-scale tourism and housing projects without new resilience safeguards
