Abstract
In this paper we present a new approach for evaluating forest fire static risk. This
new methodology, based on cartographic data integration, has been applied to
Alta Murgia National Park, located in the South East of Italy, to identify fire
more vulnerable areas. The static risk resulted strongly dependent on factors
which are constant or which are varying very slowly with time, such as
morphological factors (exposition, inclination), environmental static factors (soil
use and vegetation coverage) and human factors (urban areas extension, road
network, restoring activity centres, fire recurrence during the past five years at
least). Moreover, on the short time, fire risk (particularly fire start and
development) results strictly related to different factors such as vegetation factors
(types and density, maintenance management rules), orographic factors (altitude,
sides exposition and inclination, insulation), meteorological factors (air
temperature, air humidity, wind velocity and direction, last ten days cumulated
rain). The methodology we used is based on a step by step procedure for the
calculation of any of the factors mentioned above. Data processing has been
realized in a GIS (Arcview 3.2) environment using overlay procedures. The
result is a chart representing five levels of fire risk (static) with a resolution of 30
m. Significantly helpful resulted fuzzy logic applications for previous indicators
integration. This kind of procedure, which allows remote sensing data as well as
local measured data assimilation, gives to local authorities a highly versatile tool
for fire risk localisation and for Alta Murgia Park resources optimal planning and
management.
