Geoprocessing Applied to Risk Assessment of Forest Fires in the Municipality of Bodoquena, Mato Grosso Do Sul

Abstract

-Forest fires are a permanent threat in urban-forest interface areas and cause considerable environmental damage, especially in protected areas. An efficient way to assist decision-making to prevent an increase in forest fires is risk assessment using geographical information systems (GIS). The objective of this study was to evaluate the risk of forest fires in the municipality of Bodoquena, Mato Grosso do Sul, Brazil, using remote sensing data and spatial analysis techniques implemented in a GIS. The procedures of the methodology are based on spatial analysis techniques to prepare maps of the likelihood of fire based on calculations of the Euclidean distance, the Kernel statistical method and fuzzy transformation and to combine these maps via the increasing diffuse overlay method. The results showed a high risk of forest fires on the margins of the urban area, rural settlements and main roads that cross the municipality, as well as the surrounding areas. It is concluded that the municipality of Bodoquena has a high risk of forest fires in areas with high biodiversity, especially the areas surrounding the Serra da Bodoquena National Park and Mato Grosso do Sul Pantanal.

Co2 Emission Trends and Risk Zone Mapping of Forest Fires in Subtropical and Moist Temperate Forests of Pakistan

“…The availability of forest fire risk zone mapping aids in the precise evaluation of the fire (Jaiswal et al, 2002). This risk-mapping involves the multi-criteria evaluation method that includes factors such as slope, elevation, aspect, land-use, climatic conditions, proximity to roads and settlements (Bacani, 2016;Mukete et al, 2018b). One of the most common practices of risk zoning is the assigning of the subjective layer to all classes according to the sensitivity of fire and ignition capabilities (Dong et al, 2005).…”

Avaliação da Vulnerabilidade Social à ameaça de Fogo na Microrregião Tomé-Açu

“…Embora já existam sistemas de vigilância das florestas com emprego de imagens de satélites e órgãos como IBAMA (Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis), INPE (Instituto Nacional de Pesquisas Espaciais) e outros em âmbitos federal, estadual e municipal, atuando no monitoramento e prevenção de focos de incêndios, estes eventos ainda são um sério problema, pois ainda se observa um incipiente manejo ambiental diante da larga expansão da agricultura e da bovinocultura em imensas áreas no país (Bacani, 2016;Anderson et al, 2019;Souza et al, 2021). Políticas públicas e pesquisas científicas voltadas para a questão da prevenção e controle de incêndios florestais ainda estão muito aquém do ideal, já que estudos recentes apontem para a questão do aumento de incidência de desastres associados a incêndios florestais no Brasil (Anderson et al, 2019, Anderson & Marchezini, 2020.…”
