This project aims to explore how mega-fires phenomena is currently evolving in this country, which factors are determining their occurrence and the consequences for ecosystems and human well-being.

Objectives


  • Evaluate how mega-fires in the 10 or 20-year return time are trending in the last three decades (from 1990 to 2017) in Portugal (but also in comparison to other countries in the European Mediterranean region

  • Analyze the consequences and effects of mega-fires for forest 'health' and biodiversity at several levels and scales

  • Assess which factors are related to mega-fire occurrence and their increased frequency

  • Assess the relation between mega-fires and burn severity - is average burnt severity increasing along with the maximum size of mega-fires?

  • (...)
