Espaço-Temporalidade dos Focos de Calor na Região Metropolitana de Maceió

Abstract

Resumo Este trabalho avaliou as queimadas e os incêndios na Região Metropolitana de Maceió (RMM) via dados de focos de calor (FC) disponíveis no BQueimadas para no período de 1999 a 2019. A série temporal de focos calor foi submetida às análises estatísticas descritivas e multivariadas (Análise de Agrupamento - AA) juntamente com Vegetation Health Index (VHI) aplicadas aos FC nos municípios da RMM. Com base no agrupamento hierárquico identificaram-se três grupos homogêneos (G1, G2 e G3) de FC e o município de Atalaia que não se agrupou (NA). Os Grupos G1 (145,5 ± 7,77 FC) e G2 (28,5 ± 44 FC) apresentaram similaridades quanto à sazonalidade dos FC. Enquanto o Grupo G3 (91 ± 7,07 FC) que inclui a capital Maceió, apresentou distribuição irregular espacialmente. Toda a variabilidade dos FC está associada às atividades agrícolas vigentes na RMM. Mas também, à negligência de ateio de material inflamável sobre a vegetação propicia aumento de incêndios e queimadas, principalmente na colheita da cana-de-açúcar.
