We collected a sample of 185 participants, professional and voluntary firefighters, who directly participated in suppression activities for the Pedrógão Grande and October 2017 wildfires in Portugal. They were on duty in 149 fire stations in the Central Region of Portugal. A questionnaire was sent via Google Form to participants, based mainly on close-ended and two open-ended questions. It was structured into topics concerning the characteristics of wildfire events, the problems that occurred during the suppression activity, the emotional response of participants to the events, the lessons learned, and the consequences. We found significant differences between the two groups in their perception of wildfire characteristics and their perception of the worst fires they had ever experienced. Some differences were f...

Method’s implementation passes through methodical principles of inspection of the fire scene at ground level and or from an elevated position, the step by step analysis of marks left by fire, the examination and record of materials present.

It is necessary to learn how to coexist with wildfires. Several initiatives have been proposed to increase buildings resistance and the reduction of fuels. In this chapter is discussed the Fire Smart Territory (FST) concept, as a holistic planning philosophy, acting at territory level. On the one side, it presents an alternative to fuel management, a very expensive activity, proposing the introduction or maintenance of productive activities that break landscape continuity and connectivity, assuring a blanket reduction of fuel load, contributing to decrease vulnerability of the exposed local communities and, consequently, losses and damage. On the other side, the perspective of acting on concerned communities, by empowering them, can be obtained through training, recovery of traditional wisdom, and knowledge, and enhancing their resilience leading to reduction of vulnerability and retur...

Recent events in Portugal, Chile, Greece, Australia, Canada, and the USA provide evidence that EWEs are an escalating worldwide problem, exceeding all previous records. Despite the challenges put by climate change, the occurrence of EWEs and disasters is not an ecological inevitability. In this chapter the rationale of the definition of EWEs and the integration of potential consequences on people and assets in a novel wildfire classification scheme are proposed and discussed. They are excellent instruments to enhance wildfire risk and crisis communication programs and to define appropriate prevention, mitigation, and response measures which are crucial to build up citizens' safety.

In one stand (S(1)) the trees were completely burned ('charred’), in the other one (S(2)) the trees were only ‘scorched’, with a crown in part still alive
