Analysis of the Surface Temperature and Environmental Fragility of the Municipality of Arujá, State of São Paulo – Brazil

The Municipality of Arujá is located northeast of the Metropolitan Region of São Paulo (RMSP) between the Cantareira and Itapeti mountains, along the Presidente Dutra Highway (BR-116) and along the banks of the Baquirivu-Guaçu and Jaguarí rivers. Because it is a municipality of significant environmental importance for the RMSP, given its still large green area, it was necessary to apply geoprocessing techniques with the objective of analyzing the potential and emergent fragility, in the sense of pointing out necessary areas of conservation and / Or environmental mitigation. However, the work showed that the potentially more fragile areas were those located in the NNE portions of the municipality. In these, the geomorphological domain of high hills associated with high slopes, pointed to the necessity of conservation of these areas, considering that these lands are still covered by large arboreal vegetation and free of urban occupation. On the contrary, the areas of the municipality located in the SSO portions, this fragility that was previously potentially low today, is presented as an emergency, mainly due to the urban occupation.
