| Resumo: | The occurrence of wildfires and fires in natural environments is a predominant factor in environmental degradation and biodiversity loss. Conservation Units (CUs), on the other hand, act as notable tools for environmental protection/conservation in Brazil and worldwide. Despite the implementation of these units, the presence of degrading activities in protected territories still occurs significantly, where, in several cases, natural resources are illegally exploited, altering landscapes. The Environmental Protection Area (APA) of Chapada do Araripe presents a notable natural abundance in its territory, biotic elements, fauna and flora, and abiotic elements such as geological formations and geomorphological features, in addition to a significant availability of water sourcesa geodiversity that requires conservation actions given the nature of its management category and extensive area. In this perspective, this research aims to analyze landscape transformations caused by wildfires and fires in the APA of Chapada do Araripe between the years 2000 to 2020, as a contribution to the management and administration plan of the referred UC. For the development of the work, bibliographic surveys through a systematic review, documentary, cartographic, and iconographic surveys of data on the APA of Chapada do Araripe were carried out a UC located in the northeast of Brazil, covering parts of the states of Ceará, Piauí, and Pernambuco. Subsequently, the NBR burn index was applied to identify and measure burned and fire-affected areas within the APA, for which multispectral satellite images from the Landsat series were acquired for the years 2000, 2005, 2011, 2015, and 2020. In light of this, the results show that landscapes with higher rates of wildfires and fires in the APA are composed of savannah formations (caatinga), mostly arising with the aim of clearing the soil to make way, primarily, for agricultural activities. The NBR yielded satisfactory results in identifying burn and fire scars during mapping. Overall, demands aimed at expanding the management and supervision of the APA are essential for reducing the exploitation and degradation of natural resources in its territory, especially as it is a very extensive area that spans three states and has a limited technical management team (employees and inspection agents), hindering conservation and supervision actions in this environment. |
