Análise Do Desmatamento Nas Áreas De Influência Da Br-421 E as Pressões Sobre Áreas Especiais No Oeste De Rondônia

Abstract: O objetivo da pesquisa é analisar as principais alterações antrópicas nas áreas de influência da rodovia BR-421 e as pressões sobre o meio físico, em parte das áreas especiais do tipo terras indígenas, localizadas no oeste de Rondônia. Foram utilizados métodos indiretos de análise, nomeadamente o processamento digital de imagens e o cálculo de um índice de pressão antrópica. Além do uso dos métodos indiretos empregou-se um questionário para avaliar a percepção de estudantes indígenas que residem numa das terra… Show more

“…Approximately 50% of the area is occupied by the following protected areas: the Karipuna Indigenous Land, the Guajará-Mirim State Park, the Jaci-Paraná Extractive Reserve and the Igarapé Lage Indigenous Land. The region is inserted in the zone of influence of the BR-421 and RO-420 highways, one of the most conflictive areas in the state of Rondônia, with high rates of deforestation [84][85][86]. The region is also characterized by the incidence of fires [87], induced by the accelerated process of illegal occupation in these protected areas since 2014, following the expansion of the road network within them [85,88].…”

“…Em se tratando das vias de acesso, o desmatamento no Sudeste Paraense é particularmente severo ao longo das principais estradas de penetração entre as quais a Rodovia Transamazônica (BR-230) é um exemplo emblemático (Ávila, et al, 2017). Esse padrão de desmatamento as margens da rodovia, corrobora com alguns estudos sobre a dinâmica de desmatamento na Amazônia (Soares-Filho et al 2006;Fearnside et al 2009;Lopes et al 2019) constatando, nesse caso, que a forma de ocorrência do processo é Research, Society and Development, v. 9, n. 11, e2999119887, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i11.9887 sempre o mesmo, mas em locais e em situações diferentes.…”
