Wildfire is a global phenomenon responsible in each summer for tremendous environmental, social and economic losses. In the last two years, many lives were lost during the fires occurred in Portugal, Greece and California. The conjunction of land abandonment, long drought periods, flammable monocultures, lack of forest management and urban development planning, resulted in an unprecedented destruction. This phenomenon have become a persistent threat worldwide, and this risk may increase in the future due to the combination of future fire-prone climate, together with the recent trends of afforestation, land abandonment and fire suppression.
A reflection focused in these variables is essential to understand the recurrence of these extreme fires, and the consequent fatalities that occurred in Portugal, California and Greece. These high-severity mega-fires have also an important impact on the environment as a result of the reduction of vegetation cover and high volatilization of nutrients. Despite the fact that several ecosystems such as the Mediterranean have a high resilience to fires, the high wildfire recurrence is reducing their capacity for recuperation, contributing importantly to land degradation.
The aim of this session is to join researchers that study fire effects on the ecosystems, from prevention to suppression, wildfire modelling, climate change impacts on fire and post-wildfire impacts, either by means of laboratory, field experiments, or numerical modelling. It is time for scientists to join their strengths to give accurate answers to prevent and mitigate the effects of wildfires.
