In Mediterranean regions across Europe, the EU-funded Med-IREN project is working with nature through the development, upscaling, and replication of nature-based solutions (NBS) to reduce disasters stemming from more frequent extreme weather events. This is especially relevant given that much of the grey infrastructure built to defend against these risks has been increasingly unable to keep pace with the accelerating impacts of climate change.

The project is exploring how nature-inspired solutions can be integrated with engineering practices to protect communities from floods, wildfires and other climate hazards. In Granollers, the capital of Catalonia’s Vallès Oriental region, northeast of Barcelona, the project team is restoring riverbanks and applying phytoremediation techniques at Can Cabanyes, an eight-hectare riverside nature reserve south of the city.

By planting carefully selected vegetation, the MED-IREN is protecting the reclaimed water distribution system from erosion and flooding. In addition, these plants also help filter and remove contaminants from the water, reducing the need for chemical treatments in polluted areas. Plans are also underway to create a second wetland within the nature reserve to further support water purification and improve flood and erosion control.

Although Catalonia is one of the European regions most exposed to climate-related risks, by implementing diverse strategies that combine sustainable technological innovation and nature-based solutions the region is enabling a proactive response for local communities to actively build resilience to the increasing pace and intensity of climate change.
