Em todo o Mundo o Risco de Incêndio Florestal é quantificado. Em Portugal existem dois modelos postos em prática, o FWI (Fire Weather Index), adoptado pelo Instituto de Meteorologia e o Modelo do Instituto Geográfico Português. O primeiro é obtido através de variáveis meteorológicas e é calculado a curto prazo. O segundo, com previsões a longo prazo, além das condições meteorológicas, considera também factores biofísicos, como a topografia, a vegetação e a densidade populacional. Nestes modelos de previsão não foi ainda integrado de forma efectiva a dimensão social, na qual resulta a percepção das pessoas acerca do risco de incêndio. A população actua directamente no risco de incêndio com as suas acções, tanto na ignição, como no combate aos fogos florestais. Este trabalho teve como objectivo avaliar essa dimensão e comparar com modelos de previsão de risco de incêndio. Os dados obtidos, ainda que preliminares, apontam para uma ordenação dos riscos de incêndio associados aos diferentes usos da terra diferente daquela que é utilizada nos modelos de avaliação de risco para os concelhos de Trás-os-Montes. No que respeita ao tipo de propriedade do solo, os dados apontam para as propriedades colectivas (baldios) com tendo maior risco de incêndio. Por fim...

O risco de incêndio e seus prejuízos às vidas humanas e ao patrimônio tornaram-se cada vez maiores com o desenvolvimento urbano e a evolução da construção civil. Assim, os meios de proteção contra o incêndio tornam-se cada vez mais necessários, tanto os meios ativos (sprinklers, brigada de incêndio, etc), quanto os meios passivos (proteção térmica de estruturas, etc). Em situação de incêndio, a proteção à vida e ao patrimônio deve ser garantida pelos meios de proteção das edificações evitando-se o colapso de parte ou toda estrutura. A eventualidade do sinistro não deve ser desprezada sendo que, melhorar o desempenho das estruturas visando a iminência de um incêndio é sinônimo de economia em um aspecto abrangente: proteção à vida, ao patrimônio e à atividade econômica desenvolvida no estabelecimento. Neste trabalho, realiza-se uma apresentação do tema comportamento das estruturas de concreto em situação de incêndio, abordando aspectos de análise de risco incêndio, seguro contra incêndio, o fenômeno incêndio e suas variáveis, meios de proteção térmica das estruturas e aspectos arquitetônicos e estruturais que influenciam na probabilidade de ocorrência de um incêndio. No plano experimental...

Este trabalho tem como objetivo desenvolver um método de análise de risco qualitativo que propicie um nível de segurança contra incêndio adequado ao risco esperado em uma edificação hospitalar de grande porte, visto que o estrito atendimento às exigências de códigos e regulamentações prescritivas podem não garantir um adequado nível de segurança contra incêndio. O método baseou-se na metodologia de análise de risco qualitativa e em técnicas de gestão de risco corporativo. O trabalho resultou no Método de Avaliação de Risco Incêndio Hospitalar (MARIH). O MARIH foi idealizado com o intuito de demonstrar que, a partir da identificação e da análise dos principais riscos de incêndio em edifícios hospitalares, é possível tomar medidas adequadas para minimizar tais riscos, ainda na fase de projeto, e implementar medidas de controle (tratamento), tornando a edificação mais segura em relação à ocorrência de incêndios, sem necessariamente onerar sua construção. O método MARIH foi concebido para atuar como uma ferramenta para o desenvolvimento do projeto, com vistas a elevar o nível de segurança contra incêndio nas edificações hospitalares. Além disso, pretende-se, com o uso dessa ferramenta, demonstrar aos projetistas e empreendedores a importância da inserção adequada e da integração da segurança contra incêndio no processo de projeto de edificações de grande porte e complexas.; In view of the fact that requirements of prescriptive codes are not always enough to guarantee fire safety to hospital buildings...

Dissertação de Mestrado em Ambiente, Saúde e Segurança.; Desde sempre que o problema dos incêndios nos centros históricos urbanos preocupou as populações devido aos riscos de perdas de vidas humanas, assim como de valores patrimoniais e culturais, dos quais os edifícios são parte integrante. A localização, constituição e o estado de conservação dos edifícios existentes, aliada à morfologia dos locais onde se inserem, são algumas das características que os tornam mais frágeis e vulneráveis à deflagração de um incêndio, bem como à sua propagação a edifícios vizinhos. Estes factos justificam a necessidade de se avaliar e conhecer o risco de incêndio em meio urbano o que condiciona possíveis intervenções para melhorar a segurança contra incêndios desses centros. Esta dissertação aborda o tema do risco de incêndio em centros históricos, urbanos fazendo a sua caracterização e avaliação. Com base numa metodologia simplificada, desenvolveu-se no Núcleo Histórico de Ponta Delgada (NHPDL), uma avaliação do risco de incêndio a qual teve em consideração três fatores; a acessibilidade ao local, a disponibilidade de água para combate a incêndios e o estado geral de conservação do edificado...

This study constructed a fire risk map for the Serra de São Domingos Municipal Park (SSDMP), southern Minas GeraisSate, Brazil, which harbors Atlantic Forest remnants and endangered species. Geo-processing techniques were used for producing a preliminary risk map for altimetry (a), land slope (e), slope orientation (d), land-use/cover (u) and influence of roads and buildings (i). After, the risk maps were overlaid to produce a structural fire index (SFI)-based risk map for the Park. The SFI was calculated by using the formula SFI = 0,35i + 0,30u + 0,15d + 0,10a + 0,10e. The risks classes were classified as low (0.0-0.9), moderate (1.0 1.9), high (2.0-2.9), very high (3.0-3.9) and extreme (4.0-5.0). All data were processed with 2.5 m base spatial resolution by using the ArcView GIS. According to the SFI calculated, the SSMP area can be divided into the following fire risk zones: Low (0.93%), Moderate (61.77%), High (31.32%), Very High (4.79%) and Extreme (1.19%). The main risk factor is due to the influence of roads and buildings and most fires start due to anthropogenic causes. The low and moderate risk classes comprehend most of the rainforest area. Clearings and grasslands fit mainly the High risk class. The most vulnerable area of SSDMP was the Northern area bordering pasture...

This work provides the current status of a research effort aimed at developing a long term fire risk map of Europe, which will be included as a component of the European Forest Fire Information System (EFFIS). The fire risk model adopted for the assessment is based on the approach that combines fire occurrence and fire outcome, thus encompassing probability of ignition, estimated fire behavior and expected consequences, and aiming to integrate physical, biological and socio-economic factors. The first step has been the enhancement of the fire occurrence data stored in the European Fire Database of EFFIS, in which recorded fire ignitions exhibit a certain degree of geo-location uncertainty. Location of fire ignition points is given in most cases as administrative district without geographical coordinates. Therefore methods to approximate density estimations of the spatial distribution of fire ignition points are needed. One of the options tested in this study is the use of land cover data to constrain the geo-location of the ignition points recorded in a given administrative district inside the boundaries of the fire spatial domain (i.e. forested and wildland areas). The point distribution is made randomly or with a weighted probability filtering...

Forest fires are a major hazard to Mediterranean forests where, on average, half a million hectares of forested areas are burned every year. It is for this reason that the assessment of fire risk lies at the heart of fire prevention policies in the region. Often, the estimation of forest fire risk involves the integration of meteorological and other fuel-related variables leading to an index that assesses the different levels of risk. Two indices that are frequently used to estimate the level of fire risk are the Fire Weather Index (FWI) and the Normalized Difference Vegetation Index (NDVI). Although the correlation between the number of fires and the level of risk determined by the indices has been demonstrated; however the analysis that lead to this conclusion considered only the areas where the fires took place. The present paper analyzes the behaviour of these fire risk indices both in areas where fires took place and in those where fires did not occur. It analyzes and compares the potential of the two indices to discriminate different levels of fire risk over large areas using quantitative and graphical methods. The analysis is performed considering a dataset of 10 years of fire events, satellite data and meteorological data for Spain. The results show a better performance of the FWI over NDVI in identifying areas at risk of fires.; JRC.H.7-Land management and natural hazards

The assessment of fire risk is therefore at the heart of fire prevention policies in the region. The estimation of forest fire risk often involves the integration of meteorological and other fuel-related variables, leading to an index that assesses the different levels of risk. Two indices frequently used to estimate the level of fire risk are the Fire Weather Index (FWI) and the Normalized Difference Vegetation Index (NDVI). Although a correlation between the number of fires and the level of risk determined by these indices has been demonstrated in previous studies, the analyses focused on the changes in fire risk levels in areas where fires took place. The present study analyses the behaviour of the fire risk indices not only in areas where fires occurred but also in areas where fires did not take place. Specifically, the objective of this work was to compare the potential of the two indices to discriminate different levels of fire risk over large areas. Qualitative and quantitative methods were used to compare the statistical distributions of fire event frequencies with those of fire risk levels. The qualitative method highlights graphically the statistical difference between the values of the indices computed over burnt areas and the overall distribution of the values of the indices. The quantitative method...

Long-term forest fire risk is based on factors that remain stable for at least one fire season, giving a valuable contribution to the improvement of fire prevention systems and to the management of fire resources. This paper presents the methodology and first results for the development of a long-term forest fire risk model at the European level, based on the combination of three pillars: fire probability, fire behaviour potential and vulnerability (expected fire outcome). The methodology applied to assess fire probability and the results obtained so far for the Euro-Mediterranean region for the period 2000-2007 are described and the approach to assess vulnerability is briefly explained. Fire probability was assessed considering ignitions and the conditions for fire to spread in case an ignition occurs. Taking into account the geo-location inaccuracy associated with the fire events, fire density was used as a proxy for fire ignition and it was calculated with kernel density estimation methods. Results show that there is a high variability between and within countries, with the Northern parts of Portugal and Spain having the highest values, while Northern France and Greece have the lowest density. Portugal is the country with the highest fire density values for the whole period...

A rainforest can be modeled as a dynamic asset subject to various risks, including risk of fire. Any small part of the forest can be in one of two states: either untouched by forest fire, or already damaged by fire, in which case there is both a local forest loss and increased dryness over a broader area. In this paper, two Bellman equations are constructed, one for unharmed forest and a second for already burnt forest. The analysis solves the two equations for the total expected asset values in each of the two states, assuming that asset returns have a constant growth rate over time. The equations are used for deriving the marginal value of standing (unburnt) rainforest, equivalent to the expected discounted value loss when losing a small additional forest patch. The paper shows that marginal forest value is increased by the additional dryness and forest fire risk that follow from forest fragmentation when additional forest is lost locally. Both forest fires and dryness here serve as “multipliers” to the basic services return loss...

Fire plays a role in determining the shape of the earth's ecosystems, impacts socio-economic issues, and influences our climate. In arid and semi-arid Australia (70% of the continent), individual fires frequently exceed 1 million ha, and have collectively burnt up to 9% of the total area in a single year, associated with antecedent periods of above average rainfall which boost the fuel load. People affected by these fires – Federal and State governments, pastoralists, Aboriginal communities, larger towns, conservation park managers and tourist operators – all have different outlooks and priorities about these phenomena. Little objective information about the fire regime and its drivers has been available for this vast area with its very low population density. A predictive understanding of the spatial and temporal pattern of risk of large uncontrollable fires is needed to promote pro-active management. We present a conceptual framework which serves both to summarise existing knowledge and to reduce the complexity for a quantitative statistical analysis. This conceptual framework contains four main groups of independent variables; biomass, curing, ignition source, and fire weather. For these groups of variables we identified direct data sources or spatial surrogates. To quantify different aspects of the fire regime...

This research mapped forest fire risk for Novo Mundo County, located between the coordinates 09º09'29"S, 49°58'59"W and 10°29'28"S and 48º55'52" W, Mato Grosso State, Brazil. Using Geo-processing techniques individual risk maps for hydrograph, roads, slope and soil use and cover were elaborated. The risks were classified as null, low, high, very high, and extreme level. Afterward, the individual maps were overlaid by Overlay technical, resulting in a final fire risk zoning map. The results showed that 95% of the studied area was under high and very high risks. The variables that most influenced the risk were the boundary areas of vegetation with roads, roads with pasture and pastures and vegetation.

Artículo de publicación ISI.; A forest fire riskmodelwas designed and applied to a South AmericanMediterranean ecosystem, taking into consideration three analysis groups: fire risk; danger of fire spread, or propagation; and damage potential over economic threat values. The study area for development and validation of the modelwas theMediterranean zone of central Chile and employed data fromhistorical records spanning a 14 year period (1997–2010). Territorial data layers, combined with analysis of the statistical database and wildfire simulation have enabled areas of highest vulnerability to be definedwith greater precision, especially in sectors associatedwith the urban–wildland interface (defined as the zone where man-made structures meet wildland). Maps generated by this model have enabled improvements to be made to the traditional mapping of fires currently undertaken in South American countries. The results shown here are applicable to other Mediterranean areas, where modifications are made to the entrance variables in the risk model; Spanish Agency for International Cooperation and Development (AECID); The Program for Inter-University Cooperation and Scientific Investigation between Spain and Latin America, undertaken by the University of Cordoba...

12 pages, 4 figures.-- Online version published Aug 23, 2008.; This paper identifies human factors associated with high forest fire risk in Spain and analyses the spatial distribution of fire occurrence in the country. The spatial units were 6,066 municipalities of the Spanish peninsular territory and Balearic Islands. The study covered a 13-year series of fire occurrence data. One hundred and eight variables were generated and input to a dedicated Geographic Information System (GIS) to model different factors related to fire ignition. After exploratory analysis, 29 were selected to build a predictive model of human fire ignition using logistic regression analysis. The binary model estimated the probability of high or low occurrence of forest fires, as defined by an ignition danger index that is currently used by the Spanish forest service (number of fires divided by forest area in each municipality). Thirteen explanatory variables were identified by the model. They were related to agricultural landscape fragmentation, agricultural abandonment and development processes. The prediction agreement found between the model binary outputs and the historical fire data was 85.3% for the model building dataset (60% of municipalities). A slightly lower predictive power (76.2%) was found for the validation data (the remaining 40%). The probabilistic output of the logistic was significantly related to the raw ignition index (Spearman correlation of 0.710) used by the Spanish Forest Service. Therefore...

The aim of this research was to develop a model of forest fire risk map for Brazilian protected areas. The Cerrado State Park, located in Jaguariaíva city, State of Paraná, south of Brazil, was the focused area. The fire risk map was built up through the integrated analysis of vegetation cover (V), slope gradient (G), slope aspect (A), elevation (E), and human activities (H). For this analysis the Geographical Information System (GIS) was used. The fire risk map was the result of the overlay of the preliminary risk maps, by the model represented by the equation: RISK: 4V + 3H + 1G + 1A + 1E. The results presented that the integration model worked successfully for the area, properly managing the variables according to local characteristics and indicated two priority fire management areas in the Park. The model can be applied to protected areas with few data about fire history or few data about the area itself. The model is not recommended to be used in areas with significantly different climates.; Este trabalho teve como objetivo estabelecer um modelo de zoneamento de risco de incêndios pela análise dos fatores físicos, associados às fontes de ignição e aos fatores de propagação dos incêndios, que pudesse ser aplicado à realidade da gestão das áreas protegidas em território brasileiro.
