Análise dos focos de calor no município de Humaitá - AM, no período de 1998 a 2022

Abstract

Remote sensing has various applications, including the identification of hotspots and their association with forest fires in Brazilian territory. This study analyzed the data on the incidence of hotspots in the municipality of Humaitá in the state of Amazonas from 1998 to 2022. The research was based on the database of the National Institute for Space Research (INPE), on the BDQUEIMADAS web page, using monitoring data from AQUA reference satellites for the state of Amazonas during the period from 1998 to 2022. A total of 233,968 (two hundred thirty-three thousand nine hundred sixty-eight) hotspots were identified throughout the state, with ten municipalities in the state, including Lábrea, Apuí, Boca do Acre, Manicoré, Novo Aripuanã, Canutama, Humaitá, Maués, Autazes, and Tefé, standing out with 154,633 (one hundred fifty-four thousand six hundred thirty-three) hotspots, accounting for 66.09% of all hotspots in the state during the study period. Humaitá had 8,854 (eight thousand eight hundred fifty-four) hotspots and ranked as the seventh municipality in the state in terms of hotspot numbers in the historical data. However, it is a crucial municipality for the logistics of the southern region of the state, as it is intersected by two major highways, BR-319 (Manaus/Porto Velho) and BR-230 (Cabedelo/Lábrea). This study aimed to become an important tool for the prevention and combat of forest fires in Humaitá based on the hotspot data collected from 1998 to 2022. It also sought to serve as a reference in the study of the behavior of forest fires in the region.
