Resumo: | The emergence of forest fires may be of anthropic or natural origin, both of which cause significant socio-economic and environmental damage, and in the good part of these occurrences are resulting from Fire Foci (FF) occurrence. In recent years, Brazil has suffered from a significant increase in FF, resulting in large fires. In this way, the objective of the present study was to diagnose the spatiotemporal FF behavior in Brazil between 1999 à 2020, based on the BDQueimadas data of the CPTEC/INPE. The handling and processing of the data used the R version 3.4-1 environment software. After the data storage, it calculated the total, annual, and monthly records. And the composition of the most significant years, in this case, the years 2015, 2017, 2019, and 2020. The results pointed out that the most significant total and average annual accumulations ranged between 10-50 thousand FF and 0.5-1.5 thousand FF, respectively, concentrated in the central-northern region of Brazil, mainly in Maranhão, Pará, and the Tocantins. This pattern of high FC records is related to deforestation and agricultural expansion in these regions. On a monthly scale, the most significant occurrences of FF occur between August and November, with 0.2-0.45 thousand FF, due to starvation. In recent years, the El Niño-Southern Oscillation influenced the annual FF performance through the persistence of long stretches of styling, which resulted in a shortage of rainfall and large fires verified in 2020 in the Pantanal biome. |

En los últimos años, Brasil ha sufrido el aumento significativo del FC, al que han provocado grandes incendios. De esta manera, el objetivo del presente estudio fue diagnosticar el comportamiento espacio-temporal del FC en Brasil entre 1999 y 2020, basado en los datos BDQueimadas del CPTEC/INPE. Para el manejo y procesamiento de los datos, se utiliza el software de entorno R versión 3.4-1. Tras el almacenamiento de los datos, se calcularon los registros totales, anuales y mensuales, y la composición de los años más significativos, en este caso, los años 2015, 2017, 2019 y 2020. Los resultados señalaron que las acumulaciones anuales totales y promedio más grandes oscilaron entre 10-50 mil FC y 0,5-1,5 mil FC, concentradas en la región centro-norte del Brasil, principalmente en los estados de Maranhão, Pará y Tocantins. Este patrón de altos registros de FC está relacionado con la deforestación y la expansión agrícola en estas regiones. En una escala mensual, las ocurrencias más grandes de FC ocurren entre los meses de agosto y noviembre, con valores de 0,20-0,45 mil FC, debido al período de agitación. Se encontró que en los últimos años, la Oscilación del Niño-Sur influyó en la incidencia del FC a través de la persistencia de largos tramos de estilismo, lo que resultó en una escasez de lluvias y gran incendios verificados en 2020 en el bioma Pantanal.O surgimento de incêndios florestais pode ser de origem antrópica ou natural, ambas causam grandes prejuízos socioeconômico e ambiental, e em boa parte dessas ocorrências são resultantes da ocorrência de Focos de Calor (FC).

Desta maneira, o objetivo do presente estudo foi diagnosticar o comportamento espaço-temporal dos FC no Brasil entre 1999 e 2020, baseados nos dados de dados BDQueimadas do CPTEC/INPE. Para a manipulação e o processamento dos dados, utilizou-se o software de ambiente R versão 3.4-1. Após o armazenamento dos dados, calculou-se os registros totais, médias anual e mensal, e a composição dos anos mais significativos, neste caso, os anos de 2015, 2017, 2019 e 2020. Os resultados apontaram que os maiores acumulados totais e médios anuais variaram entre 10-50 mil FC e 0,5-1,5 mil FC, concentrados na região centro-norte do Brasil, principalmente nos estados do Maranhão, Pará e Tocantins. Este padrão de alto registros de FC está relacionado ao desmatamento e expansão agrícola nessas regiões. Em escala mensal, as maiores ocorrências de FC ocorrem entre os meses de agosto e novembro, com valores de 0,20-0,45 mil FC, devido ao período de estiagem. Verificou-se que nos últimos anos, o El Niño-Oscilação Sul influenciou a incidência dos FC através da persistência de longos períodos de estiagem, que resultaram em escassez de chuvas e grandes incêndios verificados em 2020 no bioma Pantanal.Research, Society and Development2021-06-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1661210.33448/rsd-v10i7.16612Research, Society and Development; Vol. 10 No. 7; e3731071612Research, Society and Development; Vol. 10 Núm. 7; e3731071612Research, Society and Development; v. 10 n. 7; e37310716122525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/16612/14900Copyright (c) 2021 Carla Taciane dos Santos; Washington Luiz Félix Correia Filho; José Francisco de Oliveira-Júnior; Dimas de Barros Santiago; Bárbara Alves Batistahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSantos, Carla Taciane dos Correia Filho, Washington Luiz FélixOliveira-Júnior, José Francisco deSantiago, Dimas de BarrosBatista, Bárbara Alves2021-07-18T21:07:03Zoai:ojs.pkp.sfu.ca:article/16612Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:37:06.977170Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
