ICFBR 2011International Conference on Fire Behaviour and RiskAlghero, Italy - October 4-6, 2011personnes aux sources de danger se produise non pas dans les maisons, mais dans les rues, lorsqu‘elles se dirigent vers un lieuplus sûr. Par ailleurs, en ce qui concerne la Méditerranée, les cas montrent que les maisons sont faites avec des matériauxfondamentalement non inflammables et lorsque celles-ci brûlent et sont détruites, c‘est parce que le feu pénètre et enflammeles matériaux inflammables à l‘intérieur de la maison. Dans la plupart des pays de la Méditerranée, une plus grande densité demaisons substitue généralement une réduction de combustibles disponibles. Ainsi, la maison et la densité de routes, ainsi quel‘agrégation modifient fortement l‘expansion de l‘incendie, le comportement de l‘incendie, et également la distribution spatialedu risque (Caballero et coll., 2007). Cet article examine les opportunités et les limites de différents types de modèlesd‘interface péri-urbaine (WUI) par rapport à la gestion efficace d‘une urgence d‘incendie en fonction de situations réelles danslesquelles l‘éducation et la formation des personnes sont aussi importantes que la gestion du combustible et la préparation desstructures pour la conception et le développement d‘une communauté résistant à l‘incendie.34
ICFBR 2011International Conference on Fire Behaviour and RiskAlghero, Italy - October 4-6, 2011WUI.4 - An analysis on Wildland Urban Interface in PortugalRibeiro L.M. 1 , Viegas D.X. 21. Forest Fire Research Centre (CEIF/ADAI); Rua Pedro Hispano n 12, 3030 - 289 Coimbra, Portugal; 2. CEIF/ADAI.Dep. Mechanical Engineering, Univ. of Coimbra, Portugalluis.mario@adai.ptThe problem of forest fires in the Wildland-Urban Interface (WUI) is a growing issue not only in Portugal butworldwide where fires tend to coexist with increasing frequency and danger with human presence in dwellings orsettlements. Some of the worst wildfire disasters involving human losses are precisely associated with the approach offire to settlements, as was the case of Greece in 2007 or Australia in 2009. A simple definition of WUI is thephysical space where vegetation and structures coexist in a fire prone environment. In Portugal this is applicable to alarge extension of the territory. Although there is some work done is European countries, there is still a gap in theresearch and understanding of the WUI problem concerning its characterization and real extent. This work aims topresent a diagnostic analysis and characterization of the problem performed for Portugal. The main objective was theproduction of a WUI risk map at a regional level identifying high priority areas in terms of structural and humanexposure to wildfire. Given the scale of the work as well as the financial means and input data available for this studythe methodology used is mainly based on the use of free data sources. A catalogue for the identification of WUIsituations and the respective associated risk was the basis for its assessment. This catalogue, that was adapted frompublished bibliography, aims to be representative of Portugal, and it allows a fast and precise way to identify WUIsituations comparing real cases to an intuitive photographic key. This photographic key associates a risk class to eachWUI typology. The catalogue of WUI situations is divided into 3 groups, according to the main land use wherebuildings are established: A) forests, B) shrub lands and C) agro-forestry. In total 21 different situations compose the3 groups of the catalogue. Each one of these situations has a correspondent risk value associated, from 1 (low) to 4(very high). The work consisted of an individual analysis of each of the considered regions (Portuguese districts). Inevery district a value of presence for each situation of the catalogue was attributed. Values of presence range from 0(non-significant) to 3 (very frequent). The results were then merged with other relevant information (land use, firehistory…) in order to produce individual analysis for each district. The proposed methodology can be adapted toother regions of Europe with similar types of house construction. Extension of the typology to other types ofstructures is the vicinity of the forest or rural areas is being developed.Keywords: wildland-urban interface; risk assessment; free data sourcesIl problema degli incendi forestali nell‘interfaccia urbano-rurale (WUI) è un tema sempre più importante non solo inPortogallo ma in tutto il mondo, in quanto gli incendi tendono a coesistere, a causa della crescente frequenza epericolo, con la presenza dell'uomo nelle abitazioni o negli insediamenti. Alcuni dei disastri più gravi che comportanoperdite umane sono appunto legati alla prossimità dell‘incendio agli insediamenti, come visto nel caso della Grecia nel2007 o dell‘Australia nel 2009. Una semplice definizione della WUI è lo spazio fisico dove la vegetazione e lestrutture coesistono in un ambiente soggetto a incendi. In Portogallo si applica a una grande estensione del territorio.Sebbene sia stato realizzato qualche studio nei paesi europei, ci sono ancora lacune nella ricerca e nella comprensionedel problema della WUI riguardante la sua caratterizzazione e la reale estensione. Questo lavoro mira a presentareun‘analisi diagnostica e una caratterizzazione del problema effettuata per il Portogallo. L‘obiettivo principale è statoquello di produrre una mappa del rischio della WUI a livello regionale che individui aree ad alta priorità in termini diesposizione agli incendi delle strutture e dell‘uomo. Data la scala del lavoro nonché i mezzi finanziari e i dati di inputdisponibili per questo studio, la metodologia utilizzata è principalmente fondata sull‘uso di fonti gratuite di dati. Uncatalogo per l‘individuazione di realtà di WUI e il relativo rischio collegato sono stati presi come base per talevalutazione. Questo catalogo, che è stato adattato dalla bibliografia pubblicata, vuole essere rappresentativo delPortogallo e permette di identificare in modo rapido e preciso le realtà di WUI confrontando i casi reali con unachiave fotografica intuitiva. Questa chiave fotografica associa una classe di rischio a ogni tipologia di WUI. Ilcatalogo delle realtà di WUI è diviso in 3 gruppi, secondo il principale uso del territorio dove sorgono edifici: A)foreste, B) macchia e C) agro-forestale. In totale, 21 situazioni diverse compongono i 3 gruppi del catalogo. Ciascunasituazione ha un valore di rischio corrispondente a essa associato, da 1 (basso) a 4 (molto alto). Il lavoro è consistitoSESSION 2: Fire Risk at WUI35
