Análise da resiliência socioecológica em um projeto de assentamento convencional do sudeste paraense
(Universidade Federal do Pará, 2018-04-30) CARVALHO, Alderuth da Silva; VIEIRA, Ima Célia Guimarães; http://lattes.cnpq.br/3761418169454490; https://orcid.org/0000-0003-1233-318X
Southeastern Pará state, Amazon region, Brazil, is known as the agricultural frontier and scenario of numerous land conflicts. In the same region, under the agrarian reform policy, the federal government implemented some 500 Settlement Projects (SP). Among them, stands out the Conventional Settlement Project "26 de Março", in the municipality of Marabá-Pará. This SP, result of the process of occupying almost 10 years of encampment in Farm Cabaceiras, was formally created in 2009. Its organicity is managed by the Landless Rural Workers Movement (MST) and is the pioneer settlement with environmental license. Taking as reference the social and environmental relations that influence each other, we characterize rural settlements as socioecological systems, which, inserted in the debates about sustainability in the Amazon, allow us to apply the theory of resilience. The objective of this work was to analyze the socioecological resilience of the conventional settlement PA "26 de Março". To help us in this analysis, we chose to use the methodology of resilience indicators, composed of two dimensions, four components and 14 indicators that received scores of 1 to 5 (one to five). These indicators made up the questionnaire that guided the interviews applied between September and October of 2017 to a sample of 20% of the owners of lots occupied in PA "26 de Março", Marabá. Responses were interpreted to identify which punctuation they indicated. The scores provided us with subsidies to find out which components represented fragility or potentiality for socioecological resilience of the housing nuclei (Núcleo de Moradia) of the settlement, besides enabling us to make a categorization test of the socioecological resilience level of the settlement as a whole. The results showed that, at the "Núcleo de Moradia" level, the "knowledge, learning and innovation" component represents a negative trend towards resilience for all "núcleos de moradia", as well as for the settlement as a whole. On the other hand, we perceive as potential of strengthening of the resilience the component "Organicity and infrastructure". According to the resilience categorization, the PA is considered with level of socioecological resilience "Reasonable". This result indicates a threshold between the fragility and the potential for strengthening socio-ecological resilience. In this way, we consider immediate training / qualification actions for the settlers, as well as the promotion and / or strengthening of social technologies aimed at respecting biodiversity and peasant family farming. We conclude that socioecological resilience thinking is pertinent and allows us rich debates on the way of understanding socioecological systems, such as rural settlements in the Amazon.

Análise de indicadores sustentáveis urbano em uma mesorregião amazônica, Brasil.
(Universidade Federal do Pará, 2022-03-29) SILVA, Elisane Gabriel do Nascimento; VITORINO, Maria Isabel; http://lattes.cnpq.br/4813399912998401; https://orcid.org/0000-0003-3253-5301
Global concerns about environmental degradation have emerged since the 1970s, reflected in conferences, meetings, reports, among others, carried out by the United Nations (UN), which international agreements arise in favor of preserving the world's biodiversity. Perceptions on Sustainable Urban Development encompass the conceptualizations of evolution, social awareness and environmental conservation. In order to measure global Sustainable Development, the Agenda 30 published by the UN comes into force, with 169 goals, broken down into 254 indicators, which they do not assess municipal sustainability. The objective of this study is to propose a system of indicators that allows the analysis of urban sustainability in the face of the social, political-institutional and environmental dimensions of the municipalities of the Metropolitan Mesoregion of Belém. The Urban Sustainable Indicators Matrix (MASU) was designed using that data collection carried out through internet sites, at no cost to the researcher. To validate this proposal, two methodologies were applied: the Likert Scalar method (adapted), and the Principal Component Analysis (PCA) method, that analyzes results are divided into two chapters. The results obtained by the Likert Scale method (adapted) point to sustainability by the indicators of the Social Dimension and unsustainability by the indicators of the Environmental and Political-Institutional Dimensions, consecutively, highlighting the municipalities of Belém and Santa Bárbara do Pará as sustainable, and the municipalities of Marituba, Inhangapi and Castanhal as unsustainable. The sustainability achieved by the municipalities infers cities with Sustainable Development, although this sustainability is associated by the relative analysis of the data sample. While the application of the PCA method showed sustainability in by the indicators of the Social Dimension and unsustainability by the indicators of the Political-Institutional Dimension, highlighting the municipalities with Sustainable Development being Barcarena, Santa Barbara do Pará, Inhangapi and Santa Isabel do Pará as sustainable, due to the criteria of signs and similarities, measured through the data of the Principal Components (CPs). That way, MASU highlighted realistic results, showing (un)favorable indicators for local sustainability, providing subsidies to public management to solve specific problems and develop effective public policies to meet the needs of the population and achieve Sustainable Urban Development.

Oil palm cultivation is a spatial process fostered by actions between the State and the business sector, enabling the expansion of oil palm cultivation in the Amazon. As a research focus, we argue that oil palm cultivation emerges as a central activity in monoculture expansion in the Amazon, bringing a series of socio-environmental damages, especially in the Tomé-Açu Microrregion (MRTA). The research consists of a multifaceted analysis, from the historical context and set of laws that facilitated the expansion of oil palm plantations, to the application of advanced geoprocessing techniques and remote sensing to detect and understand changes in land cover and land use. Thus, the general objective is to understand the expansion of oil palm cultivation as a source of socio-environmental damages in the Tomé-Açu Microrregion, PA. The chapters of this dissertation were written in the format of scientific articles, corresponding to chapters 2, 3, and 4. The study area is the Tomé-Açu Microrregion, in northeastern Pará, and we used the Arauaí settlement and the Jambuaçu quilombola territory as clipped portions from the study area. The methodology consisted of literature review, supervised classification of satellite images, and field visits to communities impacted by oil palm cultivation. We perceive the persistence of the discourse promising economic and social integration of rural areas adapted to oil palm cultivation. There is no room for discussion of alternative proposals for rural economic integration, nor is the peasant way of life considered in the conception of integration projects. Geoprocessing techniques proved to be efficient in identifying oil palm plantations and detecting deforestation associated with the expansion of oil palm monocultures. Between 1988 and 2023, 32,322 hectares of forests (primary and secondary) were converted into oil palm plantations in the MRTA. Family farmers associated with the production chain are irreversibly linked to oil palm cultivation. Residents of Jambuaçu suffer from pressure on the territory caused by industrial oil palm cultivation.

As dimensões do risco hidrometeorológico na cidade de Vigia de Nazaré-Pa, Zona Costeira paraense
(Universidade Federal do Pará, 2022-06-30) BARRETO, Cairo Eduardo Carvalho; COHEN, Julia Clarinda Paiva; http://lattes.cnpq.br/0293299378753887; https://orcid.org/0000-0003-2048-8915; PIMENTEL, Marcia Aparecida da Silva; http://lattes.cnpq.br/3994635795557609; https://orcid.org/0000-0001-9893-9777
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.

The Amazonian savannas are extremely important for the conservation of biodiversity, being composed of vegetation communities of numerous endemic species. However, the Amazonian savannas are poorly studied. Forest areas of the Amazon have been monitored since 1988 when the Amazon Monitoring and Deforestation Project (PRODES) was created to obtain annual gross deforestation rates of the Brazilian Legal Amazon. However, PRODES does not monitor non-forest areas (NF) within the Amazon biome, restricting information about nonforest formations, their environmental diversity and degree of anthropization. Thus, the general objective of this work is to analyze the landscape dynamics in non-forest formation areas in the periods of 2000, 2015 and 2020. This research has as an area of analysis an area of NF (Amazon-Cerrado transition ecotone) located in the municipalities. of Rio Maria, Redemption, Araguaia Forest, Conceição do Araguaia, Santa Maria das Barreiras, Pau D'arco and Santana do Araguaia, southeast region of Pará State, area of recent settlement process. To perform LULC mapping of the land, the Google Earth Engine (GEE) platform was used. It is a catalog of ready-made analytics data with a high performance, intrinsically parallel computing service. When analyzing the results by thematic class, it was observed that the Savannah Park, Agriculture and Others classes presented a higher agreement 90%. The Pasture and Savannah Wooded classes had lower agreement, with 80%. The classes that represented the highest intensity of omission were Wooded Savannah with 10% and Other 7%. Inclusion, had the highest values in the pasture with 13% and Agriculture or Pasture 7%. The overall accuracy of this mapping was 86%. The GEE platform proved to be efficient and agile, which allowed several sorting attempts to be made in the shortest time until the best possible result was achieved with excellent validation results.

Fragilidade ambiental na bacia do rio Mocajuba - PA
(Universidade Federal do Pará, 2020-02-17) CAVALCANTE, Juliane da Costa; LIMA, Aline Maria Meiguins de; http://lattes.cnpq.br/6572852379381594; https://orcid.org/0000-0002-0594-0187
The hydrographic basin of the Mocajuba River has been densely occupied by the expansion of human activities. In this way, anthropization jeopardizes the permanence of the natural ecosystems and mangroves in this region. In this context, this work presents the dynamics of the landscape in the Mocajuba River basin between 1999 and 2018 and its implications for the natural fragility of the basin and the continuity of the mangroves in this region. To this end, the research is divided into the following items: (1) Analysis of land use and land cover in the hydrographic basin of Rio Mocajuba - PA, using the Object Oriented Classification (GEOBIA) and the Google Earth Engine platform as methods (GHG), in conjunction with the Random Forest classifier. (2) Application of the Potential and Emerging Environmental Fragility methodology, using natural data from the basin (pedology, geological units, altimetry and rainfall) in conjunction with anthropogenic data (land use and cover). (3) Temporal analysis of the mangroves in the basin between 1984 and 2018, observing the expansion and regression of this ecosystem, as well as the anthropic and environmental tensors to which they are susceptible. The land use and land cover classification methodologies presented different quantifications and accuracy. For 1999, the GEOBIA and Random Forest classification presented a Kappa coefficient of 0.79 and 0.92, respectively. For 2018, the coefficient was 0.73 and 0.8, respectively. For both methodologies, the class of Forestry Formation suffered a decrease and Non-Forestry increased. For the Mangrove class, the GEOBIA classification quantified an increase and the Random Forest decrease. In the environmental fragility methodology, the levels of potential and emerging fragility obtained were low, medium and high. Where 19.92%, 76.67% and 3.41% of the basin showed low, medium and high potential fragility, respectively. For emergent fragility, the mangrove and non-forest areas increased the natural fragility of the basin and the forest formation class provided an attenuation of this. In this case, the areas of low, medium and high emerging fragility were quantified at 18.39%, 67.57% and 14.04%, respectively. Mangrove areas decreased between 1984-1999 and 1999-2018. The data presented confirm the expansion of the anthropization of the basin and the interference of human activities in the dynamics and response of the mangroves in the face of natural tensors. As confirmed by the increase in the natural fragility of the basin provided by the expansion of these activities. In this way, the research becomes relevant for providing a systemic analysis between different areas, seeking to understand the functioning of the basin ecosystem, assisting in future research and initiatives.

Geoheritage is an extension of geodiversity that comprises elements of geological nature with heritage values, whether educational, scientific or cultural ones. Seeking their preservation, geoconservation comes up with discussions that aim at the protection, management and dissemination of geological heritage in its various forms. When it comes to natural heritage, we also consider the protection of ecosystems and socio-environmental dynamics. In this research, we analyze the geoconservation of the paleontological heritage of the municipality of Salinópolis, state of Pará, Brazil. The goal was to identify and propose subsidies for the conservation of the paleontological geoheritage of Salinópolis, considering the connections between geosciences and society. For this, we carried out a survey of scientific data on the fossils and paleontological sites of the city as well as interviews with representatives of Salinópolis, to check on the demands of public management. We also carried out a quantitative assessment of the paleontological site at Atalaia Beach, aiming its future recognition in the national inventories. It was possible to observe that there is an extensive scientific record of the salinopolitan geoheritage, which has been studied since the 19th century. However, this knowledge is restricted to the academic community, since city managers are unaware of the topic, in addition to the lack of collaboration between research institutions and the city hall. Moreover, the city’s sites are not mentioned in environmental conservation policies, precisely because they do not have formal recognition, although the site has high educational and tourist value in our assessment. Because of the importance of society’s role in the construction of heritage perceptions, it is necessary to change the perspective of science on geoheritage, in order to approach society in a democratic way, building sustainable relationships among science, population and the environment.

História Ambiental do Alagado do Piry de Jussara, Belém-PA : uma reflexão acerca da ocupação urbana em áreas alagadas.
(Universidade Federal do Pará, 2021-05-20) SILVA, Marcus Vinicius Silva da.; LIMA, Aline Maria Meiguins de; http://lattes.cnpq.br/6572852379381594; https://orcid.org/0000-0002-0594-0187
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.

Mudanças de uso e cobertura da terra e vulnerabilidade ambiental da bacia hidrográfica do Rio Arauaí, Moju/PA.
(Universidade Federal do Pará, 2022-02-28) SANTOS, Bruna Mykaelle Pereira; SILVA, José Francisco Berrêdo Reis da; http://lattes.cnpq.br/1338038101910673; https://orcid.org/0000-0002-8590-2462
The investments that Pará started to receive from the launch of the Agroecological Zoning of Palm Oil and the Program for Sustainable Production of Palm Oil (PPSOP), in 2010, made possible the expressive expansion of the palm culture in the northeast of Pará, where it found conditions ideal climate for this. Since then, national and international companies have been installed along the highways of Pará aiming at agricultural exploitation. In this context, the Arauaí River Basin (BHRA) is inserted, in the municipality of Moju/Pará, Eastern Amazon. In view of the panorama, the present research seeks to quantify and map the spatial distribution of the levels of environmental vulnerability of the BHRA caused by human activities and natural aspects, having as main aid the Analytical Hierarchy Process (AHP) statistical methodology developed by Saaty (1980) and geoprocessing, in addition, the change in land use and cover is sought, having as a time frame the Program for Sustainable Production of Palm Oil (PPSOP) with the help of Geographic Information System (GIS) and Remote Sensing. Based on the results, it was possible to define areas with 5 different degrees of environmental vulnerability - Very Low, Low, Moderate, High and Very High, in addition to verifying that the amount of area converted to oil palm was basically the same in the pre-PPSOP and post-PPSOP period, with the change being due to the amount of area converted from primary forest to oil palm, which decreased in the post-PPSOP period.

Relação entre diâmetro do caule e espessura da casca das árvores amazônicas e sua implicação na resistência ao fogo
(Universidade Federal do Pará, 2024-03-28) GAMA, Valter Thiago Pantoja da; FERREIRA, Joice Nunes; http://lattes.cnpq.br/1679725851734904; https://orcid.org/0000-0002-4008-2341; BARLOW, Bernard Josiah; http://lattes.cnpq.br/8559847571278134
The characteristics of plants are important for understanding their functions and relationships with the environment and the functioning of ecosystems. Tropical forests, such as the Amazon, are important for promoting ecosystem services that are important for maintaining biodiversity and human well-being. However, these forests are facing major threats due to human interference, especially climate change and forest fires. Therefore, given this scenario, research focused on forest resistance to disturbance regimes can help in the monitoring and conservation processes of this type of biome. Therefore, the aim of this study was to evaluate the relationship between stem diameter at breast height (DBH) and bark thickness in tropical Amazonian forests, in order to identify the significance of the relationship between these variables and the possible effects on the degree of forest resistance to fire. The study was carried out using forest inventory data from 21 plots in the Lower Tapajós, in the Eastern Amazon - PA. In order to assess the relationship between DBH and bark thickness, data from 11 botanical families was used in a GLMM (Generalized Linear Mixed Effect Models). The relationship between the variables was significant, with an overall explanatory power of 34% for DBH over thickness, and considering the variation between botanical families, this power increased to 50%. Our results show that of the 11 botanical families studied, only half have trees with bark thick enough to be considered resistant (17-23 mm). In addition, in order to consider trees with or without resistance potential, we analyzed bark thickness at a minimum DBH of 10 cm and the increase in bark thickness as DBH increased. Fabaceae, Lecythidaceae and Burseraceae stood out as being more prone to fire mortality. Therefore, considering the high distribution of individuals belonging to these families in the Amazon and the current scenario of forest degradation, ecological impacts and climate change, this work raises insights into the Amazon's forest vulnerability to burning regimes, and the importance of its conservation for climatic conditions on a local and global scale.

The colonization of northeaster Pará is considered one of the oldest at Amazon area, where a disorderly occupation over time caused several impacts on the environment and water resources, mainly related to the territory of the hydrographic basin of the Marapanim River. In this context, the research aimed to integrate concepts of water demand and availability, adding hydrological and socio-environmental factors to the analysis of the hydrographic basin as a natural unit of area for the management and application of public policies in the municipal cities of Castanhal, Igarapé-Açu, Marapanim, São Francisco do Pará and Terra Alta, which belong to the hydrographic basin of the Marapanim River. The goal of the research was to evaluate the management process of those localities, through sustainability index with Pressure - State - Response (PER) indicators, combined with the characterization of multiple uses of water. The main demand for water in those localities is public water supply, with an estimated volume of 2,228.18 m³ / day. However, within the limits of the locality, agriculture was the activity that were responsible for the higher demand, 28,022.46 m³ / ha, followed by livestock production, 899, 82 m³ / day. The region's water availability was estimated by rainfall monitoring, in which September-October-November were months with fewer rainy days, with the highest percentage of rainfall in the month concentrated in a few days. The sustainability index of the municipal cities of Castanhal, Igarapé-Açu, Marapanim and Terra Alta were 0.40; 0.50; 0.44; 0.54 and 0.5 respectively, which represents an average value. The city of São Francisco obtained an index value of 0.54, considered as a good index value. The characterization of multiple uses of water is essential to understand the relationships of availability and demand for water that occur at hydrographic basin of the Marapanim River, as well as the application of the sustainability index based on the pressure - State - response model, allowing both integrated and individual assessment of hydrological, environmental, political and social indicators, which allows a more targeted view of the needs of each territory, thus helping to guide public policies managers during decision making process.

The transition from urbanization in developing countries to the global environment of environmental degradation associated with changes in land use, has had adverse consequences for the individuals and ecosystems involved. The occupation process of Brazilian cities triggered a population settlement movement in places unsuitable for occupation, such as coastal areas, places with fragile soil, where different situations of risk and social and environmental vulnerability. In this context, the objective of this study is to analyze the characteristics of social and environmental vulnerabilities in the municipality of Barcarena-Pa, using statistical and cartographic data. Regarding the social and economic data surveyed, the main source used was the demographic census of the IBGE for the year 2010, normalization of variables, factor analysis and therefore the data generated were overlaid on a map. For environmental analysis, geological, geomorphological, pedological, rainfall and land use mapping was carried out. The map algebra technique was used to generate the vulnerability map. In an overview, it is noted that the municipality of Barcarena has an explicit deficiency in incorporating economic gains in favor of social and environmental benefits, since almost the entire municipality is at a high rate of social vulnerability, and even few locations where the social and most favored part, environmental vulnerability leads to a high risk scenario, especially in the rainiest months, which occurs between December to May. This study becomes an important tool for environmental planning and social intervention, since the challenge of sustainable development is a reality in modern societies that needs to be achieved through effective and humanized strategies and policies that combine socio-economic development and environmental defense, that is, a urgent problem.
