Leading the way to climate resilience
Nature-based Solution and Community-led adaptation
Our mission is to demonstrate that Nature-based Solutions (NBS) are vital for efficient and effective climate adaptation.
ARCADIA brings together 8 European regions and communities — 5 model regions (Italy, Croatia, Austria, Denmark, Sweden); 3 fellow regions (Bulgaria, Romania, and Slovenia) — to accelerate the adoption of NBS and to provide access to the latest, evidence-based knowledge, tools, and services.
Discover more about our objectives and results, our model and fellow regions, resources, and tools to contribute to empower European regions and communities by 2030. Explore and stay informed with the latest news and events!
