The fires in Hawaii, which have left at least a hundred dead and hundreds missing, have devastated entire towns and villages and have put the issue of how to prevent such intense fires back on the table. World Wildfire Prevention Day is celebrated this Friday 18 August. The increase in the occurrence and recurrence of large wildfires jeopardizes the resilience of socio-ecological systems. Efforts in prevention must be a priority and constant throughout the year. We have a joint responsibility as a society to face this unprecedented problem, which will worsen in the coming years.
