With the intensification of industrial processes since the 18th century, the urban population has grown significantly, causing degrees of urbanization that can reach 90% in Brazil. The advance of accelerated and disordered urbanization, the expansion of the metropolises and the irregular use of the soil implied several impacts on the environment - both natural and built - and disturbances to society. Therefore, this study aims to analyze the growth of the neighborhood of Pedreira, located in the city of Belém/PA, articulating problems of the urban environment with the historical evolution of the neighborhood. In order to relate these issues, bibliographic reviews were first made to analyze the urban and environmental consequences present in the neighborhood; documentary research was also carried out, using remote sensing scenes available on the United States Geological Survey (USGS) website of the Global Visualization Viewer (GloVis) platform, as well as satellite images provided by Google Earth. The generated scenes were treated in the spring © software, available on the website of the National Institute for Space Research (INPE) and ArcGIS, for a more contrasting view of green and urbanized areas. Finally, exploratory research with on-site observations was used to reinforce the data on the environmental impacts resulting from the urbanization of Pedreira. This study hopes to contribute to demonstrate how the accelerated urbanization process is related to the environmental quality of that neighborhood.
