Abstract

Among the occurrences that affect urban areas, there are floods and flooding, considered natural hydrological disasters, which become more noticeable due to the lack of planning and infrastructure. Thus, the objective of the research was to analyze the temporal dynamics of the Metropolitan Region of Belém (RMB), from a socio-environmental perspective, and its relationship with natural disasters in the period from 2010 to 2021. To this end, indicators were collected in the Automatic Recovery System (SIDRA) of IBGE and in the National Sanitation Information System (SNIS) of the Ministry of Regional Development. The results indicated that in RMB, the volume of sewage collected is considerably higher in relation to the treated one. The difference in the population quantity citing the sewage collection service is also significant, with households that do not have one prevailing. The extension of water and sewage networks did not keep up with population growth. The data proved that the lack of planning consistent with the structural and environmental conditions of the region contributed to the chaos scenario experienced in RMB. It is understood that the research is useful to support the adoption of public policies regarding the losses caused by these occurrences, as well as to prepare for future events.
