註釋

Episodes of extreme wildfires around the world together with the evidence of physical limits in extinction capacity under extreme fire conditions show that strategies focusing on fire suppression are not effective to deal with novel fire risks. Although upgrading analytical capacities and technological based solutions in emergency management is necessary, in the current context of climate change, fire regime changes point to the need of a paradigm shift from fire suppression to fire resilience. The present research aims at operationalizing this adaptation gap by applying a new transdisciplinary approach consisting in the use of unplanned fires as landscape planning tools, a window of opportunity where emergency responders can turn wildfires into prescribed burnings, and in such a contra-intuitive way emergency management can increase landscape resilience at medium-long term. This disruptive fire policy is based on the conceptualization of the fire ecological flow, a novel concept defining the quantity, quality and timing of fire required to achieve a regime footprint in a particular socioecological system that provides for human uses, maintains essential processes to support healthy forest ecosystems while reducing the vulnerability to collapse in front of extreme events or simultaneity.Based on landscape modeling, we identify key environmental factors to assess potential impacts depending on different alternatives and fire ecological flows. Thus, potential benefits, vulnerabilities, and areas for improvement to mitigate adverse effects have been identified. This strategic innovation at the socioecological scale represents the first official attempt approved in Europe for managing unplanned fires as an ecological process and restoring fire regimes in the current climate emergency context. Although the framework is implemented in the specific region of the Aran, it may have a wider application in the Pyrenees as well as in other European mountain areas sharing similar challenges.
