This research aims to contribute to the discussion on resilient cities adapted to climate change in the face of global warming and El Niño. In this context, a strategic resource for addressing this reality is the use of green areas as nature-based solutions, due to their environmental and social benefits. This study analyzes land use planning, vegetation, alignment of environmental policies, the municipal Master Plan, the institutionalization of the 2030 Agenda for Sustainable Development's 17 Sustainable Development Goals (SDGs 11, 13, and 15), and adaptation to the New Urban Agenda adopted by the management of the municipality of Barcarena, PA. To do so, a methodology of systematic literature review was employed on urban planning, environmental management, green areas, nature-based solutions, environmental legislation, global and local agendas, and the theme of resilient cities in adaptation and mitigation to climate change. In order to understand the territory, the study produced primary data through the mapping of Land Use/Land Cover (LULC) in the thirty neighborhoods of the municipality and its surroundings (approximately 3 km) between 2016 and 2023. Remote sensing techniques and geoprocessing were used, processed in Google Earth Engine and QGIS software for spatial analysis, statistics, cartographic productions, graphs, and area calculations. Current urbanized area data show that vegetation has decreased and occupies 144.56 km2 (54% of the total area). Hydrography remained stable at 57.48 km2 (representing 22% of the total). Exposed soil increased to 26.22 km2 (10%). The urbanized area grew and occupies 17.62 km2 (7%). The current industrial-mining-port complex covers 18 km2 (7%). Regarding the 30 neighborhoods, current data shows that vegetation has decreased and occupies 21.36 km2 (41.51% of the total area). The urbanized area expanded and occupies 18.94 km2 (36.80%). Exposed soil increased to 11.15 km2 (21.67%). Meanwhile, hydrography remained unchanged at 0.01 km2 (0.02%). The study reveals a Vegetation Coverage Index (VCI) of 10.97%, indicating a decline in greenery, and low thermal comfort with the Vegetation Coverage Heat Index (VCHI) at around 9.66 m2/inhabitant, has heat islands. The research proposes as a product: data, maps, and methodology for the elaboration of the Urban Environmental Registry, to contribute to the alignment of municipal management with the State Plan for the Recovery of Native Vegetation and with the Decade of Ecosystem Restoration. It aims to be a tool to aid in future environmental zoning and the next Master Plan Review, with actions focused on the city's resilience, in the face of worsening climate crisis, aiming to contribute to the promotion of urban environmental quality and quality of life, for local sustainable development.

Na “beira” do cais, o centro englobador em risco: perspectivas e possibilidade de reordenamento da orla de Abaetetuba/PA
(Universidade Federal do Pará, 2022-05-30) SILVA, Dalgisa da Conceição Araújo da; SOUZA, Alexandre Augusto Cals e; http://lattes.cnpq.br/2652815221358066; https://orcid.org/0000-0002-1424-5055
This work proposes to analyze the process of transformation that has been developing along the urban riverfront of the municipality of Abaetetuba/PA, occupations in the Amazonian landscape, in areas protected by the course of tides and riparian forests in areas that should be protected. These occupations constitute areas of vulnerability, where the risks are present in the houses built in areas of water courses, in areas of erosive soil, in a caused way and without protection infrastructure, a fact that culminated in a disaster that occurred in 2014 in the São João neighborhood: a landfill collapse destroyed 13 (thirteen) houses and, as a result, 51 (fifty one) families were supported by the disaster. In a similar way, this occupation process also affected other areas of the riverside, mainly the commercial side, which I call here the encompassing center, as it is a historic neighborhood with economic and cultural potential, where one of the largest open-air fairs in the region. I followed this accident while working at the Municipal Civil Defense Coordination, and I was able to see firsthand the suffering of people who had losses of all kinds, and who were no longer able to return to their homes. This fact motivated me to question how to rearrange risk areas in already consolidated urban spaces, in order to prevent new disasters from occurring. The risk scenario takes place in Abaetetuba, in areas of different land uses and occupations, areas of social vulnerability, environmental protection, commercial flow, concentration of urban equipment and an area of historical memory. In this way, I analyze the process of transformation of the riverside neighborhoods of Abaetetuba as the formation of risk areas for the development of a proposal and planning that considers the risks and vulnerabilities present in these territories. Based on the research results, it was found that, despite the history of disasters in these places, the existing urban structure and the lack of a risk management plan that protects the riverfront contributed to the risk scenario that is presented. In this way, it is necessary to take into account the possibilities of public intervention based on improvements in existing planning instruments and the elaboration of new ones, which include the diagnosis of the areas, monitoring and a differentiated treatment for the risk areas in which the population participates. of the process. The research was carried out through data collection and application of semi-structured questionnaires with public sector agents and civil society to enable a more efficient planning proposal. The research was conceived in a multidisciplinary analysis in which contributions from municipal plans and scholars from the areas of geography, environment, social sciences and urban policy are articulated.
