COST Action CA22164
An International Network Focused on Improving Understanding of Extreme Wildfire Events
While rare and extreme wildfires have occurred in the past, recent catastrophic events point to the emergence of novel fire regimes characterized by extreme wildfire events.
Although significant advances have been made in understanding such events, much work remains to enhance our capability to identify when a wildfire may evolve into an extreme event. This is a complex challenge that requires re-evaluating current paradigms and introducing new frameworks.
NERO addresses this challenge by bringing together wildfire researchers and practitioners to advance the science.

Why It Matters
Extreme wildfire events require coordinated international research and real-world application of scientific knowledge. NERO fosters collaboration between researchers and practitioners, promotes capacity building, and raises awareness among both fire operatives and the public.

What We Do
NERO brings together data and expertise to support the process-based analysis of extreme wildfire events. We raise awareness and build capacity to better anticipate and respond to such events across science, operations, and policy.

Our Vision
We aim to break disciplinary silos and open new avenues for understanding extreme wildfires. By bridging science and practice, we seek to enhance operational capacity across Europe and beyond.
NERO by the Numbers
A growing network of researchers and practitioners shaping the future of extreme wildfire events research across Europe and beyond.
