Fire scenario definition
Luis GALIANA & Cristina MONTIEL
Territorial sphere which features shared characteristics in the initial conditions and possible evolution and impact of wildfire
Instrument for the establishment of homogeneous strategies of wildfire prevention and extinction
Fire scenarios are defined at the national, regional and local scale (different objectives andmethods)

Regional Fire Scenarios(1:50.000)
CONCEPTUAL BASIS = WILDFIRE GENERATION
1st Generation: - Area with continuous fuel load- Recent abandonment of farmlands
(Quite large wildfire perimeters)2nd Generation: - 10-15 years of abandonment of agricultural and forest management
- Fuel continuity and homogeneity (shrubland)(High fire propagation intensity and spread)3rd Generation: - High fuel density and vertical continuity(Crown fire out of control)4rd Generation: - Wildland-urban Interfaces
- Fuel continuity and estates(Great fire intensity and jumps)
The concept of wildfire generation is associated with the different stages of landscapeevolution. It relates to a model of wildfire evolution towards a situation of predominance oflarge wildfires, which show high intensity and overwhelm control capacity. All this relatedto the variations of available fuel, framed within a determined spatial and temporal context, which prompt changes in action strategies
