Dinâmica espaço-temporal dos regimes de fogo em áreas protegidas do Maranhão: impactos do manejo integrado do fogo

Abstract

This study analyzed the spatiotemporal dynamics of fire regimes in protected areas of the Brazilian Cerrado from 2001 to 2024, focusing on two conservation units (Chapada das Mesas National Park and Mirador State Park) and two Indigenous Territories (Governador and Bacurizinho). The main objective was to investigate the influence of the Integrated Fire Management (IFM) on fire frequency and intensity, as well as the relationship between vegetation types and fire regimes. Satellite images from the Landsat series and data from MapBiomas were used, along with geotechnologies for fire scar mapping and vegetation classification. The results show that areas with IFM implementation exhibited greater control over fire and a reduction in burned area over time, while areas without IFM maintained unstable and recurring fire patterns. It is concluded that IFM is an effective strategy to mitigate fire impacts, promote the conservation of native vegetation, and strengthen environmental management in protected areas of the Cerrado
