HISTORICAL PROFILE OF THE BURNED AREAS BASED ON MODIS PRODUCTS IN THE CONSERVATION UNITS OF CEARÁ – BRAZIL

Abstract

This study aims to understand the historical profile of burned areas in the Conservation Units (UCs) of Ceará, using MODIS data from 2001 to 2022. Geoprocessing tools were used to generate statistics, including the number of burned areas, total area affected, annual and monthly distribution, size, and frequency of burns. The main results indicated 1006 burned areas covering 28854.39 ha, with the federal APA Chapada do Araripe and APA Serra da Ibiapaba leading the way with 87.49% of the total. State APA The Serra de Baturité stood out with 634.83 ha burnt. The federal APA The Chapada do Araripe recorded burn-offs every year, with 2005 being the year with the greatest impact. The second half of the year saw the largest areas burned, especially in October, November and December. Most of the fires (80.62%) were of class III size (4.1 - 40.0 ha), and Federal APA Serra da Ibiapaba had recurrent fires in the same area up to 5 times, totaling 11505.76 ha. The study contributes to the understanding of forest fires in the UCs of Ceará and to support the planning of preventive measures and measures to combat forest fires in Brazil.
