TITLE:

Spatio-temporal analysis of active fire spots and burned area in the terrestrial biomes of Northeastern Brazil

KEY WORDS:

SUMMARY:

Fire is an essential element for the conservation and diversity of many ecosystems. However, human activities that employ fire have led to alterations in the frequency and severity of vegetation fires, including in ecosystems not adapted to fire. The terrestrial biomes of Northeast Brazil are vulnerable to fire and present different degrees of dependency and resistance to it. In this study, we will analyze the detection of fire spots and burned areas, with the purpose of temporally and spatially comparing the NASA products MOD14A1/MYD14A1 from MODIS, on board of the TERRA/AQUA satellites, with data from the BDQueimadas fire count data base of the Brazilian Institute for Space Research (INPE) and from the Brazilian Project of Landuse and Land Coverage MapBiomas. The evaluation of these products will be conducted with respect to each of the biomes present in the Northeastern region of Brazil, aiming to identify patterns, trends, and determinant factors of these fire events. Firstly, data from the MOD14A1/MYD14A1 fire detection products and burned area for the period from 2000 to 2022 will be obtained. Fire occurrence data from BDQueimadas and burned area data from MapBiomas for the same period will also be collected. With this database, the products will be statistically compared and analyzed through both descriptive and multivariate analyses. The results will elucidate the agreement between these fire products in the specific biomes and clarify their utility in estimating atmospheric emissions resulting from vegetation fires in the region.
