Transcript of Casuality and management of forest fires in Mediterranean en

good afternoon!!!!!

Forest Fires
Natural disturbance in the Mediterranean area.

Incidence growth in the last decades

Study of casuality
"Hazard-chain" model (Hohenemser et al., 1985)
Lot of inversion in extinction. Favor naturalized stands.
Prevention (land use planning).
Debate of casuality of Forest Fires:
Why incidence growth?
Climate change; Human behaviour

Decline of traditional agriculture
compact forest masses on abandoned agricultural lands
Energy transition towards fossil fuels
no more use of biomass in domestic and industrial activities
New conservation and leisure functions of forest
open to urban population neglecting traditional uses
"Hazard chain" model
Developed by Clark University researchers in the 1980s (Hohenemser et al., 1985).
To assess more closely the relationships between casuality and management of forest fires.
Initiating event
Accident sequences
Undesired outcome
Human wants and needs
Conventional approach
Adaptation for forest fires management
Main management options land use - initiating event
initiating event - outcome
Alternative approach
Main management options in upstream parts of the chain
From management based on ignition control
To management based on
land use policies
Study case:
Bages area

Location of the study area of the affected area by the fire of July 4, 1994
In 1999,
about 98% of the forest area
colonized former agricultural fields
Bages has;
Highest forest cover in Catalonia =~ Europe
Lowest productivity in the continent

land use change and reduction of agricultural land
uncontrolled expansion of woodland
the problem is the inability to control the small number of fires
that are responsible for most of the area burnt

small proportion of fires are caused by careless conduct

the conservation of the forest masses of Catalonia

the Forestry Law of 1988
1st objective
agricultural abandonment
the low profitability of forestry facilitate the

CAUSED continuous growth of biomass
the unexpected effect of the law was turning existing forest masses

into ‘‘fire bombs’’
After the fires of 1994 and 1998, this error was RECOGNIZED

agricultural abandonment
rural depopulation
lack of resources
Using the hazard chain framework developed
by Clark researchers,
to compare conventional and alternative management options

policy orientation and social concerns

Thank you
for your attention!!
any questions??
