Resumo No Brasil, a combustibilidade da madeira e a insegurança diante de potenciais riscos relacionados a incêndios são consideradas restrições para a construção de edificações com sistemas estruturais em madeira. Essa situação é fruto do desconhecimento do comportamento da madeira em relação ao fogo. Nesse contexto, o objetivo deste trabalho é apresentar uma revisão bibliográfica abrangente sobre o comportamento da madeira a temperaturas elevadas, abordando assuntos relativos à degradação térmica, à taxa de carbonização e à influência da temperatura sobre as propriedades mecânicas da madeira. Essas informações podem contribuir para o aprimoramento de modelos numéricos sobre o comportamento termomecânico de estruturas de madeira em situação de incêndio, para a construção de edificações mais seguras e também para a eliminação do preconceito relativo ao uso desse material na construção civil.

Forest fires and burnt area in Portugal have been increasing in the last decades, contrarily to other southern European countries, although more resources are being allocated to prevention, detection and fire fighting. To minimize the probability of wildfires occurrence, it is crucial to assure the effectiveness of the prevention, vigilance and first attack operations. When fire prevention fails, fire fighting steps must be initiated, but this can only happen following detection. In Portugal the National Lookout Towers Network (NLTN) is the principal organized fire detection system, working together with some ground and aerial mobile units. However very few studies evaluated these systems effectiveness or contributed to know the lookout areas covered and which are the problematic areas not covered. In last years we characterized and evaluated the NLTN system in Portugal and produced several national cartography including visibility and vigilance priority maps. Using this cartography...

Fire of Haydarpaşa Train Station has showed us once more that we have a long way to go in the process of preparing our cultural heritage against disaster risks. Turning this unfortunate event into an opportunity for our heritage, actions to be taken before, during and after a disaster in order to reduce the vulnerability of historic buildings by means of analysing similar events that have occured in the World will be explained. Furthermore, some information will be given on the Guide for the Protection of Cultural Heritage during Rehabilitations, which is being prepared by a team of international experts. This initiation has been started straight after the Haydarpaşa Fire, by ICOMOS/ICORP- International Council of Monuments and Sites/ International Council of Risk Preparedness, Turkish Committee. Data on the situation of Haydarpaşa Train Station after the fire have been studied and used by the permission of the Directorate of İstanbul Vth Regional Council for Preservation of Cultural and Natural Heritage

Fires are one of the main factors for disturbances in Niassa Reserve-Mozambique, with economic and environmental impacts. There are cyclical records of fire occurrences across the reserve. However, studies on the main causative factors and identification of more susceptible locations are very limited. In this perspective, this study had as objectives: (1) determine the main significant factors for wildfire occurrences; (2) Map the probability of wildfire occurrences, using logistic regression. Independent variables included vegetation index (NDVI), climatic, topographic and socioeconomic data. The analysis period was from 2001 to 2015 and comprised the months with more occurrences of wildfire (May to December). According to the results, the main factors that determine the occurrence of fires were: NDVI, temperature, elevation, followed by precipitation, slope, relative humidity and human settlements. The spatial distribution of probability of fire occurrence reveals that zones with high and very high risk are located at the west and central west zones (areas with higher accumulation of dry biomass); medium risk zones are located in the centre of the reserve, while in central east and east zones the probability of fire occurrence is low and very low risk. Results showed that the expectation of wildfire ignition using logistic regression presented good precision (area under the curve 74%). ARTICLE HISTORY

Mediterranean forests are regularly subjected to a large number of fires; 537 000 hectares were burned during the severe European drought of 1990. The French Ministries of Environment, Interior and Agriculture are trying to implement efficient methods to prevent forest fires and to reduce their incidence. Fire risk is composed of human, ecological and climatic factors that are already accounted
