The city of Vigia de Nazaré, located in the Northeast of Pará, Estuarine Continental Sector of the Coastal Zone of Pará, has a historical problem of flooding, caused mainly by the effects of the tide, the rainy season with considerable accumulations of precipitation and incorporation of the fluvial-marine floodplains to the urban area. The general objective is to understand the relationship between the dynamics of floods and the occupation process in the city of Vigia de Nazaré-PA, producing a diagnosis of risk to extreme hydroclimatic events, considering temporal factors, as well as those of coastal dynamics, which in line with converge to the reality experienced by the local population. Therefore, it will be necessary to understand the process of occupation in the city of Vigia, mainly on the floodplain area, the dynamics of hydrometeorological phenomena and define the dimensions of the risk in Vigia, based on socio-environmental data. To produce the analysis, the research had data from the Centro de Hidrografia Marinha (CHM) were used, for tidal prediction, from the National Agency for Water and Basic Sanitation (ANA), to understand the seasonality of precipitation, and still, an aerial survey was carried out through a cooperation with the Management and Operational Center of the Amazon Protection System (CENSIPAM-CRBE), aiming at the production of a very high resolution Digital Terrain Model (MDT) to determine the area covered by the floodplain and an orthomosaic to visualize the urban features, among others. The socioeconomic (IBGE, 2010; IFDM, 2010) and health (DATASUS, 2014; 2016) data, in order to recognize the municipality's vulnerability to risk in relation to others in the coastal region, were adapted from another study, incorporating other health data, from a DATASUS source. Statistical and geoprocessing tools were applied to these data to compose the analyses. The main results found were: it is a historical problem, resulting from a socially constructed risk, accepted by the population and neglected by the public power; ⅓ of the occupation of the urban area is on the fluvial-marine plain, under the influence of the tide, with a large part of this area recently incorporated into the urban space, more strongly from the 1980s, in the context of the recent restructuring of the Amazon regional space. Its natural dynamics includes semi-diurnal tides, reaching 4.56 m; has an intense rainy season, for the regional characteristic of the eastern Amazon, with the highest accumulated precipitation in the months from January to May, between 307.1 mm and 489.9 mm, with the rainy quarter, FEB-MAR-ABR, passing 400 mm of rain and 25 days of average daily rainfall frequency (FDPRP). Still, there are records of flooding events affecting more than 4000 residences in the urban area, and these events were frequent during the researched historical series (1991-2020). The municipality still has a high socio-environmental vulnerability to risk, among the municipalities in the coastal region. These and other results can form a diagnosis on the hydrometeorological risk of the city of Vigia, providing subsidies for actions at various scales, whether environmental monitoring, disciplining and guiding land use and occupation, and also in investments in social areas and in the health in order to mitigate the effects of flood events.

Vulnerabilidade Institucional e sua influência sobre os problemas socioambientais na FLOTA do Iriri e APA Triunfo do Xingu, no Estado do Pará
(Universidade Federal do Pará, 2024-08-30) SANTOS, Viviane Corrêa; PIMENTEL, Marcia Aparecida da Silva; http://lattes.cnpq.br/3994635795557609; https://orcid.org/0000-0001-9893-9777
This research addresses the topic of institutional vulnerability and its contributions to the origin and increase of socio-environmental impacts in two conservation units in Pará: Iriri State Forest and Triunfo do Xingu Environmental Protection Area, which are sustainable conservation units, located in Xingu Integration Region and make up the Terra do Meio Mosaic of Conservation Units. The research's time frame is the years 2000, 2010 and 2020, a period that includes the creation of the National System of Nature Conservation Units (SNUC) and the institutionalization of the aforementioned units studied. The general objective is to problematize the State's actions that promoted the environmental vulnerability of Conservation Units, ratifying its contradiction as a managing subject. The main hypothesis indicates that the contradictions highlighted in the actions of state power contributed to the vulnerability of Conservation Units (CU) due to the lack of a clear and consistent approach in the management of these Protected Areas (PAs). To this end, the historical, dialectical and systemic materialism methods were chosen as a theoretical-methodological approach, developed in a complementary way to achieve an integrated socio-environmental analysis. The dialectical method allowed a critical and in-depth analysis of the social, political and economic relations that shape the management of these PAs, based on the understanding of the contradictions between economic development and environmental preservation, as well as the conflicts of interests between different social and institutional actors , revealing how these historical dynamics directly influence the vulnerability of conservation policies and socio-environmental degradation. The systemic method complements the development of this research based on the dynamics of the territorialized landscape and the interaction between physical and social elements, and the environmental impacts arising from agents of pressure in protected areas, contributing to the analysis of environmental vulnerability data. The preparation of the research included a survey of institutional data, carried out using institutionalized documents, interviews with technicians from the state institutions researched such as: SEMAS, IDEFLOR-BIO and BPA; open questionnaires, sent to the administrative sectors of state bodies, which were tabulated using the content analysis methodology, in addition to an interview with a resident of FLOTA do Iriri and analysis followed by tabulation of the minutes of the management councils of the study areas. Information that corroborated the cartographic production scenario prepared for analysis of this research. The results are systematized into four chapters, which identified gaps in the responsiveness and effectiveness of institutional structures. The ambiguity in the State's actions arises from the coexistence of multiple interests, including environmental conservation, economic development, political pressures and demands from civil society. It weakens the effectiveness of UC conservation and protection policies, increasing their exposure to threats and environmental degradation. Which leads to pointing out that the State is not an absent management subject, as it creates environmental policies, environmental laws, management bodies, however, environmental management is directly linked to the priority interests of the Government, which, depending on its policy , it can make legislation more flexible, make physical structures and human resources precarious, intentionally leading its institutional practices to become fragile, boosting institutional vulnerability, therefore, environmental vulnerability, to later pass the responsibility for the scenarios of environmental problems of PAs to other subjects managers.
