Vulnerabilidade e percepção de risco na planície tecnogênica em Abaetetuba-Pa: subsídios ao planejamento urbano e a gestão ambiental

Abstract

The Abaetetuba city, located in the Northeast Paraense of Pará state, was born on the river bank Maratauíra, where some neighborhoods were established such as the downtown, São João, São José and Algodoal. However, this place corresponds to a flood plain that for years has been decharacterized, it has been causing in the formation of a technogenic plain, characterized by flood events and collapse, as result this situation brings damage to the population in general. In this context, it was analyzed the vulnerability of them, with emphasis on the perception of risk as a response capacity in the intangible aspect. This element has prioritized because it had found that even after the disaster in the neighborhood of São João, however the population have been remaining in the place, making it necessary to analyze the reason for occupying these spaces. The methodology of this work used to identify the flood threat, it was based on the Junior‟s proposal (2010) based on interviews, Digital Elevation Model, Fieldwork and participatory analysis. About to the collapse in the soil was based on the report of the Mineral Resources Research Company that identified the risk of flood and mass movement in the neighborhood of São João. Anali vulnerability methodology was adapted the proposal of Slafstein (2015 ), With the construction of a Vulnerability Index of Environmental Threats in the Amazon by Perception, where social vulnerability and the capacity of response were analyzed based on people's perception of the highlighted threats, resulting in the map of vulnerability with emphasis on perception In this research it was as achieved results, the neighborhood of Centro presented Moderate vulnerability from the Index of Unit of response by Perception. The point is the fact that the population considers that there are no risks in the place have contributed to this result of this research, due to the good infrastructure of the area. The reason of permanence in the place happens due to the importance some native people for the development of commercial activities. As a contrast, The other districts presented low vulnerability in reaction to this index, presenting a perception of the threats that are present. But, the population has been remaining where threats are present until now. This occurs, due to the identity relations established in the space, whether due to family, neighborhood or the meaning of the landscape represented by the river, as it happens in the neighborhood of Algodoal and São João. Therefore, it can be consider a voluntary exposure to risk. In São José neighborhood, this happens due to economic aspects due to the importance of being close to the commercial center, symbolized by the "Beiradão". Therefore, in this case it is considered that the risk is accepted, due to the particularities of the subjects involved. From this result, it was possible to discuss the environmental planning and management in the city of Abaetetuba by proposing a territorial planning that considers the creation of Special Zones of Social Interest; Areas of Permanent Preservation; New uses for places at risk and actions of interventions to reduce losses in the face of possible disasters. It can consider that achieved results are important to subsidize environmental management and sustainable urban planning and participatory in the city of Abaetetuba.
