Lack of evidence-based Knowledge (including risk assessment and cascading effects) on fire behavior in Wildland Urban Interface areas
- Difficulty to accurately anticipate the fire development and the cascading effects in WUI areas.
- Heterogeneity of the conditions inside WUI areas, notably concerning fuel categories (buildings, gardens and natural vegetation) and spatial distribution patterns.
- Scattered presence of individuals and groups of people in an actively burning area
- Lack of risk assessment models adapted to the specific characteristics of fire behaviour and propagation in WUI areas
