Thus, political efforts are indispensable for maintaining this forest and its water resources. In this sense, the 2030 Agenda for Sustainable Development and brazilian environmental policies, such as the National System of Conservation Units, include among its guidelines and objectives various means for the protection of waters and forests. Therefore, one of the means to make these goals and other legal instruments viable are the geotechnologies, especially remote sensing. Therefore, the objective of this dissertation was to analyse and monitor environmental protection areas through geotechnologies. The methodology included the application of geotechnology tools involving both the Landsat and Sentinel-2 families satellites to two protected areas: Environmental Protection Area of the Metropolitan Region of Belém and Utinga State Park Conservation Unit. The results indicated that the region can be monitored by optical sensors even under the inherent adverse cloud conditions of the Amazon. In addition, it was possible to analyse the urban sprawl process around the protected areas and the consequent pollution and eutrophication of the study area springs, especially Bolonha Lake. Finally, it is suggested that effective measures be taken to solve the region’s environmental liabilities, given its importance for the public water supply of millions of dwellers of the Metropolitan Region of Belém.PPGCA - Estudos de ecossistemas amazônicos
