Resumo: | Changes in landscapes due to deforestation and burning are the consequence of anthropic actions that cause damage to the environment, and the use of GIS technologies favors the monitoring of these changes. The objective of this research was to analyze, in a quantitative way, the evolution of deforestation and fires in the Itacaiúnas River sub-basin, with a time frame ranging from 2006-2017, with triennial intervals. To prepare the thematic maps, geographic data were collected from INPE, DETER, PRODES and BDQUEIMADAS. The acquired data were treated using the Kernel Density tool in QGis software. The analysis indicated that the triennium 2006-2008, recorded greater extension in deforestation (n = 162.10 km2) and fires (n = 5,586) differently from the years 2012-2014 with lower occurrences in these aspects (deforestation, n = 15.93 km2; fires, n = 595 focuses). The 10 municipalities of the sub-basin presented relevant averages for deforestation (n = 23.0 km2/year) and fires (n = 828.8 focus/year), with Marabá standing out for manifesting the largest deforested area and fires focus ( = 106.4±95.1). Lower values of deforestation were found in Curionópolis ( = 1.1±1.2), while Sapucaia indicated the smallest fires ( = 32.0±28.4). With these data one can identify the main capitals involved in these two actions in Marabá: cattle ranching, because between 2009-2011, this activity suffered an increase equal to 32%. As deforestation is frequent in this municipality, it is advisable to use as pastureland, those areas that no longer have vegetation cover to mitigate deforestation. |

El objetivo de esta investigación fue analizar, de forma cuantitativa, la evolución de la deforestación y los incendios en la subcuenca del río Itacaiúnas, con un marco temporal que va de 2006 a 2017, con intervalos trienales. Para la elaboración de los mapas temáticos se recogieron datos geográficos del INPE, DETER, PRODES y BDQUEIMADAS. Los datos adquiridos se trataron con la herramienta Kernel Density del software QGis. El análisis indicó que el trienio 2006-2008, registró mayor extensión en deforestación (n = 162,10 km2) e incendios (n = 5.586) a diferencia de los años 2012-2014 con menor ocurrencia en estos aspectos (deforestación, n = 15,93 km2; incendios, n = 595 focos). Los 10 municipios de la subcuenca presentaron promedios relevantes de deforestación (n = 23,0 km2/año) e incendios (n = 828,8 focos/año), destacándose Marabá por manifestar la mayor área de incendios deforestada ( = 106,4±95,1). Los valores más bajos de deforestación se encontraron en Curionópolis ( = 1,1±1,2), mientras que Sapucaia indicó un menor número de incendios ( = 32,0±28,4). Con estos datos podemos identificar los principales capitales involucrados en estas dos acciones en Marabá: la ganadería, porque entre 2009-2011, esta actividad sufrió un aumento igual al 32%. Como la deforestación es frecuente en este municipio, es aconsejable utilizar como pastizales, aquellas zonas que ya no tienen cobertura vegetal para mitigar la deforestación.Alterações nas paisagens por desflorestamento e queimada são consequência das ações antrópicas que ocasionam danos ao meio ambiente, e o uso das tecnologias de SIG favorecem o monitoramento dessas modificações. O objetivo dessa pesquisa foi analisar, de modo quantitativo, a evolução do desflorestamento e queimadas na sub-bacia hidrográfica do rio Itacaiúnas, com recorte temporal compreendido entre 2006-2017, com intervalos trienais. Para elaboração dos mapas temáticos, coletaram-se dados geográficos do INPE, DETER, PRODES e do BDQUEIMADAS. Os dados adquiridos foram tratados com uso da ferramenta densidade de Kernel em software QGis. A análise indicou que o triênio 2006-2008, registrou maior extensão em desflorestamento (n = 162,10 km2) e focos de queimadas (n = 5.586) diferentemente dos anos 2012-2014 com menores ocorrências nesses aspectos (desflorestamento, n = 15,93 km2; queimadas, n = 595 focos). Os 10 municípios da sub-bacia apresentaram médias relevantes de desflorestamento (n = 23,0 km2/ano) e queimadas (n = 828,8 focos/ano), com destaque a Marabá por manifestar a maior área desflorestada focos de queimadas ( = 106.4±95.1). Valores menores de desmatamento foram ao município de Curionópolis ( = 1.1±1.2), já Sapucaia indicou menores focos de queimadas ( = 32.0±28.4). Com esses dados pode-se identificar os principais capitais envolvidos nessas duas ações em Marabá: pecuária, pois entre 2009-2011, essa atividade sofreu um incremento igual a 32%. Como o desflorestamento é frequente nesse município, é de bom alvitre que se utilizem como pastos, aquelas áreas que não possuem mais cobertura vegetal para haja uma mitigação no desflorestamento.Research, Society and Development2021-03-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1325510.33448/rsd-v10i3.13255Research, Society and Development; Vol. 10 No. 3; e34010313255Research, Society and Development; Vol. 10 Núm. 3; e34010313255Research, Society and Development; v. 10 n. 3; e340103132552525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/13255/12050Copyright (c) 2021 Layla Bianca Almeida Dias; Paulo da Silva Garcia; Lucimar Costa Pereira; Antônio Pereira Juniorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDias, Layla Bianca Almeida Garcia, Paulo da Silva Pereira, Lucimar CostaPereira Junior, Antônio2021-03-28T12:03:35Zoai:ojs.pkp.sfu.ca:article/13255Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:38.805831Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
