In 2023, storms battered the Hauts-de-France Region in France and the Aa river delta was flooded. This experience revealed how vulnerable the low-lying region is to climate change. The institutions in charge turned to EU-funded Interreg Europe to explore adaptation options to build resilience against both floods and droughts. This work led to a peer review study from Belgium, Estonia, the Netherlands, Spain, and the United Kingdom. As part of this work, water management governance, the possibility of using nature-based solutions, such as meadow areas and flood plains, were discussed and shared with stakeholders from across the region.
