[pt] O fogo constitui um dos grandes fatores da transformação da paisagem, particularmente as florestais. O mapeamento de risco de incêndios, utilizado para determinar quais áreas são suceptíveis ao início de um incêndio florestal, visa abordar algumas estratégias contra o fogo e levantar a discussão sobre a importância da prevenção de incêndios em unidades de conservação. Para o desenvolvimento do mapa de risco de incêndios do Monumento Natural Estadual Serra dos Mascates, foram utilizadas seis imagens temáticas representando: o uso e cobertura do solo, altimetria, declividade, orientação de vertente e a proximidade ao centro urbano, assim como seus acessos (estradas e trilhas). Todas as imagens foram reclassificadas para mesma classe e sobrepostas utilizando um coeficiente de risco. A sobreposição final reclassificou as áreas com risco Alto às bordas da área urbana e das vias de acesso, ressaltando a influência da atividade humana no risco de ignição do fogo. / [en] Fire is one of the major factors in landscape transformation, particularly forest ones. The fire risk mapping, used to determine which areas are susceptible to start a forest fire, aims to address some strategies against fire and raise the discussion about the importance of preventing fire in conservation units. Six thematic images were used for the development of the risk map of the Monumento Natural Serra dos Mascates representing: land use and cover, altimetry, slope, slope orientation and proximity to the urban center, as well as its access (roads and trails). All images were reclassified to the same class and superimposed using a risk coefficient. The final overlay reclassified the areas with High risk to the edges of the urban area and access roads, highlighting the influence of human activity on the risk of the ignition.

A risk assessment study is conducted in a denim manufacturing plant in Turkey. The study is carried out within the framework of a project on adopting the Integrated Pollution Prevention and Control (IPPC) Directive of the European Union. The scope of the assessment is fire or explosion risk with regards to hazardous chemicals present in the plant. The receptor of the study is defined as &ldquo / people&rdquo / which include the employees in the plant, employees of nearby plants and people in residential around the mill. A semi-quantitative risk assessment is carried out using checklist, a risk matrix and risk evaluation forms. The highest risks in the plant are identified as dust explosions, natural gas jet fires, natural gas explosions. Also, it is identified that due to several causes, in case of a fire or explosion the scale of an accident may enlarge instantaneously. The main warehouse is determined to carry the highest risk value in the plant. Mathematical modelling studies are conducted to calculate the hazard radius for dust explosions and natural gas fire and explosion. According to the results of mathematical modelling, the highest consequences could lead to destruction of buildings or severe injuries/fatalities of people within large hazard radius up to 700 m. The risk present at the manufacturing mill is communicated to the facility management throughout the study. Several suggestions are proposed to the facility management and some of them are already implemented.

Three distinct vegetation distributions were analyzed for a present day simulation (1980-2000) and for the end of the twenty-first century (2080-2100). It was demonstrated that under current conditions the PFI is able to detect the principal fire risk areas which are concentrated in the Sahelian region from December to March, and in subtropical Africa from July to October. Predicted future changes in vegetation lead to substantial modifications in magnitude of the PFI, particularly for the subtropical region of Africa. The reliability of the PFI for reproducing areas with high fire activity indicates that this index is a useful tool for forecasting fire occurrence worldwide, because it is based on regionally dependent vegetation and climate factors. / Com base em simulações de modelos climáticos regionais realizadas com o RegCM3 e reanálises do NCEP, o impacto do clima anômalo forçando a vulnerabilidade ambiental para a ocorrência de incêncios na África é analisado através da aplicação do Índice de Potencial de Fogo (PFI). Três distribuições distintas de vegetação foram analisadas por uma simulação atual (1980-2000) e para o final do século XXI (2080-2100). Foi demonstrado que em condições atuais o PFI é capaz de detectar as principais áreas de risco de fogo, que estão concentradas na região do Sahel, de dezembro a março, e na África subtropical, de julho a outubro. Previsão de futuras mudanças na vegetação levam a modificações substanciais na magnitude do PFI, particularmente para a região subtropical da África. A confiabilidade do PFI para a reprodução de áreas com alta atividade de fogo indica que este índice é uma ferramenta útil para a previsão de ocorrência de incêndios em todo o mundo, uma vez que se baseia em fatores regionais dependentes da vegetação e clima.
