Abstract
In Galicia (Spain), wildfires are one of the main environmental problems, with
an annual average of close to 8,600 forest fires between 1999 and 2008. Most of
these fires are intentionally ignited. It is therefore crucial for fire prevention
policies to assess human-started fires and their relationship with socioeconomic
aspects. In this paper we focus on the spatial pattern of human presence in the
territory as an important determinant on forest fires ignitions. We identify,
classified and map wildland-urban interface (WUI) and assess fire risk by types
of WUI in a Galician county with one of the highest incidence of forest fires
during the studied period (1999-2008). Following Lampin-Maillet et al.
(Mapping wildland-urban interfaces at large scales integrating housing density
and vegetation aggregation for fire prevention in the South of France. Journal of
Environmental Management 2010) approach, and based on a combination of a
map of buildings, obtained from the National Topographic Base, and the SIOSE
land-cover map (Information system of land use cover in Spain) we
distinguished among 12 types of interfaces. Our results show a significant
relationship between the different types of WUI and the spatial patterns of
wildfire ignition points. The highest density of fire ignition points was found in
non-forest WUI with either dispersed or very dense clustered buildings.
Keywords: wildland-urban interface, forest fires risk, spatial analysis, Galicia.
1 Introduction
In Spain, wildfires are a recurrent phenomenon, with an annual average of
15,000 forest fires and 173,000 ha burned between 1980 and 2010 [3]. A
