Fire Occurrence in the Brazilian Savanna Conservation Units and their Buffer Zones

Fire dynamics in the Brazilian Savannas (Cerrado) is related to climatic conditions and management interventions by human activities. Thus, the fire occurrence in conservation units (UCs) may be different when compared with their buffer zones. Our results, obtained by burned area analysis, demonstrate that buffer zones have the most significant variation in the burned area over the years when compared to the burned area inside the UC, such as the Jalapao State Park. In contrast, when the buffer zone presents agricultural activities, as occurs in the Chapada dos Veadeiros and Chapada das Mesas National Parks, or urban occupation, such as the Brasilia National Park, the proportions of burned area are lower than found inside the UCs, according to data obtained from the MODIS MCD64A1 product from 2001 to 2018 years.
