Análise das transformações de uso e cobertura da terra induzidas por Grandes Projetos Industriais: Um estudo de caso do Pólo Gás Lub

Abstract

This study examines spatial transformations in land use and land cover (LULC) induced by the Gás-Lub Hub (formerly Comperj) in directly affected areas and zones of direct and indirect influence, covering 11 municipalities in Rio de Janeiro state. Using geospatial data from MapBiomas for 2006, 2015, and 2022, the research employs geoprocessing methodologies, including pixel-based classification and Random Forest algorithms, to map and quantify changes. The results reveal significant urban expansion accompanied by modest population growth, suggesting disproportionate spatial development and potential underutilization. Forest cover showed recovery trends, while agricultural/pasture areas decreased, reflecting shifting socioeconomic and environmental dynamics. Coastal ecosystems such as mangroves and restingas remained relatively stable with minor variations. Spatial analysis conducted in QGIS highlighted forest fragmentation and urban pressure on natural areas. The study concludes that the Gás-Lub Hub significantly influenced territorial organization, producing heterogeneous impacts that require integrated management policies. These findings contribute to understanding the effects of largescale industrial projects and suggest the need for further research on specific drivers of these transformations.
