Socio-geographic analysis of wildland fires: causes of the 2006's wildfires in Galicia (Spain)

Aim of study: To propose a methodology to establish motivations underlying wildland fire episodes by analyzing both the socioeconomics of the affected territory and the geographical distribution of the wildfire. Area of study: The wildfires occurred during 2006 in Galicia, in the NW of Spain, were analyzed and compared regard to the previous years. Material and methods: The proposed methodology in this study is divided into four steps: (a) definition of the forest context, (b) fire episode and socioeconomic data collection, (c) geospatial representation through map production, and (d) joint analysis and data interpretation. A combined analysis of the spatial and temporal coincidence of wildfire and the socioeconomic activities is performed. Main results: A combined analysis of the spatial and temporal coincidence of wildfire dynamics and the socioeconomic activities allow us to assess and to interpret wildfire causes and motivations of socioeconomic groups. In our area study, a broad analysis indicates that wildfire recurrence within this region is related to an accelerated rural flight process which exacerbates the conflict between rural and urban models. Research highlights: The socio-geographical analysis of a territory's wildfire dynamics enables us to establish possible causes and motivations of their origins. Providing the specific contextual and socioeconomic information, this methodology has potential applicability across varied study locations.
