História Ambiental do Alagado do Piry de Jussara, Belém-PA : uma reflexão acerca da ocupação urbana em áreas alagadas.

Abstract

The city of Belém has suffered since its colonization with irregular occupation over flooded areas or water courses, this problem is still evident and recurring in our city today. This problem is largely attributed to the scarcity of topographically favorable areas and the lack of adequate housing planning. In 1616 (year of the colonization of Belém), historical reports point out that in the region where Avenida Almirante Tamandaré is located today there was a flooded area, called Alagado do Piry de Jussara, however, due to the need for urban expansion, the same was seen as a natural obstacle to the irradiation of the city, and with that, it underwent canalization and grounding processes. Thus, this research aimed to carry out a historical analysis of the region that was once occupied by Alagado do Piry, aiming to understand how this occupation process took place on this natural element, coupled with this, to carry out geomorphological studies that would allow to identify the accident geographic area in which the Alagado was located, in addition to seeking to understand the complex dynamics of the waters (precipitation and tide level) that operated and still operate in the region. At the end of the study, the results obtained corroborated and confirmed the hypothesis that the form of occupation and expansion of the city that has been used since colonization is mistaken, since, in addition to not having adequate housing policies, it does not take into account account of the characteristics of the region, such as low topography, high rainfall, and periodic rising tide; which ends up causing socio-environmental problems such as floods, floods and floods in numerous points in the city of Belém. Furthermore, the study also points to the worsening of these occurrences, since the city of Belém and the Metropolitan Region are among the areas of greater susceptibility to events conditioned by climate change, such as the increase in the average sea level.
