Análise da Bacia Hidrográfica do Rio Itacaiunas (BHRI): subsídio ao planejamento ambiental
(Universidade Federal do Pará, 2021-02-22) SILVA, Ronis Cley Fontes da; ARAÚJO, Alan Nunes; http://lattes.cnpq.br/5369542452826838; PIMENTEL, Márcia Aparecida da Silva; http://lattes.cnpq.br/3994635795557609; https://orcid.org/0000-0001-9893-9777
The Itacaiunas River Basin (BHRI) has its source in the main channel located in the Serra da Seringa, in the municipality of Água Azul do Norte, state of Pará. Much of the economic resources come from mineral and agricultural exploration; consequently, the basin also faces strong environmental impacts arising from this and other activities linked to the economic use of its natural resources. With this information and others in mind, this dissertation aims to analyze the landscape dynamics in the Itacaiunas River Basin, through the application of bibliographic review methodology, cartographic elaboration, morphometric characterization, land use and occupation and diagnosis aiming subsidize environmental planning. The theoretical basis was based on the discussion about the geoecology of the landscape, highlighting the Landscape as a category of geographic research, in addition to the discussion on hydrographic basins in environmental management. The research covers three levels of analysis: characterization of the social and environmental aspects of BHRI; verification of information extracted from vector and matrix data for physiographic and fluviomorphological characterization of the basin, a stage in which it is intended to apply the morphological and vegetative indices; and the elaboration of the diagnosis and prognosis for BHRI. The research results present important data on this spatial cutout, primarily on environmental elements in addition to socioeconomic data. Subsequently, the morphometric data of hypsometry, slope, compartmentalization in high, medium and low course were analyzed, and also the hierarchy data of the channels, confirming a 5th order drainage, in addition to the morphometric data from which the conditions of susceptibility to floods. On the classes of land use and occupation, through the analysis of Landsat 8 Oli sensor images, acquired on 06/28/2020, in orbits 223, 224, 225 and points 65, 64, 4 classes were identified: Water ( 0.228%), Ombrophilous Dense Forest (41.934%), Agriculture (56.625%) and Non-Agricultural Anthropic Area (1.147%), making it possible to correlate these data with vegetative indices, presenting the spectral thresholds for dense vegetation, little vegetation and without vegetation the NDVI, SAVI and IAF values respectively (0.6729715 / 1,009 / 1,609), (0.0189145 / 0.028 / - 1.122), (-0.308115 / -1.492 / -2.949). Finally, regarding the diagnosis of the identification of environmental problems in the basin, they confirm a high degree of anthropic intervention, due to the intensive nature of land use and occupation, aggravated mainly in agricultural areas, modifying the landscape by removing vegetation cover, in addition to cause changes in the hydrological patterns of the basin. In turn, the transformations of the landscape are the result of the interaction of man with nature, which shows the need to carry out an integrated, participatory planning, according to the current scenario in the referred basin, raised through consistent and sufficient data to propose solutions. legal, through the types of land use, aiming at an ideal scenario, with the intention of reversing the current situation of the referred basin.

(Universidade Federal do Pará, 2016-03-29) TELES, Geise Corrêa; PIMENTEL, Márcia Aparecida da Silva; http://lattes.cnpq.br/3994635795557609
This study aimed to understand the dynamics of use and management of natural resources in the hydrographic basin of Mocajuba, located in the micro region of Paraense Salgado, from the landscape seizure proposed by GTP theoretical-methodological model. Something important in understanding this relationship it is understand the landscape that is being analyzed, and the processes that engender construction. The basic construction of the analysis presented and the theoretical model GTP proposed by Bertrand and Bertrand (2009), this theoretical model is a relationship between the concepts of geosystem, territory and landscape, and from that relationship you can see how to build the different landscapes. In the words of Bertrand and Bertrand (2009 p. 197) " the landscape is born when one look cross one territory." Which is to say that it is the result of understanding of the relation of territorial buildings, circumscribed in geosystem, ie the landscape is built from the perception that residents of the study area have on your living space, but that space has a base material (geosystem) and is structured on the basis of socioeconomic processes (territory) in the construction of these landscapes. To achieve the proposed objectives were developed methodological procedures outlined as bibliographic literature review on the topic and the area studied, the survey of rural ecology characteristics of the watershed, socioeconomic analysis, made from the survey data on productive activities, the mapping land use, and semi-structured interviews, accompanied by photographic records to represent the landscapes highlighted by respondents. In the survey of information on geosystem components, there is the mapping of land cover and land use, which infer important information about the conditions of the natural elements. In the survey of information about the components of the territory it highlights the conflicts identified by the use and appropriation of these resources, which are connected the main economic activities that underpin the local economy, fishing, agriculture, and crab collecting. The landscapes identified by respondents indicated the feeling of belonging, their visions of change and improvement needs in the environment where they live.

River basins are key geographic units in water resource management, and river basin problems throughout the world are mainly due to anthropogenic pressure related to land use, domestic effluent disposal, agricultural and industrial effluents, soil erosion, Deforestation, changes in the structure of the biotic communities, among others (GIORDANO et al., 2004, TANAKA, 2008 and DELINOM, 2008). The object of study of this research is the Mocajuba River Basin - BHRM, located in three municipalities of northeast São Paulo: São João da Ponta, Terra Alta and Curuçá, in the demarcation of its limits are contained two Conservation Units. In the western portion the São João da Ponta Marine Stratigraphic Reserve and in the eastern portion the Marine Extraction Reserve Mãe Grande de Curuçá. In general, this river basin has been undergoing degradation as a consequence of lack of basic sanitation, territorial occupation in inappropriate places, deforestation of mangrove areas and other areas for the expansion of agriculture, degradation of Permanent Protected Areas (PPAs), fires, Sedimentation of water bodies (ICMBIO, (2010); PANTOJA, (2012); RODRIGUES & FRANÇA, (2014); TELES, (2016)). And for lack of a management plan, it can manage its various uses. On the other hand, the Mocajuba river has a high importance for the communities that live in its surroundings, since they need their resources for their survival, given that their economic, social and cultural activities are developed in these areas. Therefore, the conservation of natural resources and the sustainable management of BHRM are considered a strategic issue from the environmental point of view, as social and economic for these populations. In this sense, the aim of this research is to analyze the Mocajuba river basin, based on the model PEIR - Pressure-State-Impact-Response as an instrument to evaluate the conditions of use and management of this natural resource, with the aim of contributing to its management . This matrix (PEIR) is structured from the identification of causal anthropic activities or sources of pressures and impacts. These activities, based on socioeconomic, on natural resources produce pressures and impacts that alter the state of its components, in order to assist in mitigation, it is proposed by society or by the public power actions (answers) that can solve or soften them. The research is considered as descriptive, exploratory and in terms of the means evaluated as a case study resulting from the process of consulting the various social and institutional actors directly involved with the environmental problems of the basin. The developed methodological model constitutes an original tool for the area of environmental management, specifically, with respect to activities that impact the environment. Regarding the variables of the PEIR model, these were analyzed based on the absence or presence of the same to the sustainability, taking into account the dimension analyzed.

(Universidade Federal do Pará, 2016-05-31) FARIAS FILHO, Daniel Vilhena; PIMENTEL, Márcia Aparecida da Silva; http://lattes.cnpq.br/3994635795557609
In the Amazon Peoples using the mangrove ecosystem to withdraw products for their livelihood are known as extractive, and if the same comply may be called Traditional Peoples. These people have a low impact lifestyle in relation to the environment and to preserve this way of life contribute to the maintenance and balance of this ecosystem. The mangrove soil is carbon storage location and the misuse of this soil makes whether this carbon is released into the atmosphere thus contributing to the greenhouse effect. Thus the Traditional Populations contribute an environmental service in global warming mitigation process. This study attempts to make the physicochemical characterization mangrove soil of São João da Ponta, in Deolândia Communities Brasilândia, Coconut and Headquarters, relating these characteristics with the way of life and the use of mangroves by the Traditional Peoples living in if environment and Sustainable Development Index of São João da Ponta (IDSM). The methodology used for the physicochemical characterization of the area was the use of pH meter for determining pH and Eh, the refractometer to determine the salinity and Walker Black method for the determination of carbon. The survey also used questionnaire in Deolândia and Brasilândia communities, in order to determine matters concerning the social part, there was also the calculation of the Municipality of Sustainable Development Index MARTINS using the formula; CANDID 2009. It was found that the areas within the RESEX in communities Deolândia, Brasilândia and coconut tree where the forest is preserved, the physical and chemical characteristics in the soil are preserved, unlike the area where there was deforestation. The calculation of the municipality of Sustainable Development Index (IDSM) was 0.548 which according to the methodology adopted prove acceptable. The application questionnaire within each community showed concern about the presence of untreated sewage, siltation of rivers arms and a practice of burning household waste at the end of the day. The conclusion shows that despite some environmentally inappropriate practices such as burning waste and removal of nearby riparian vegetation to rivers, Traditional Peoples have a low impact way of life in relation to the use of mangroves and that the existence of Resex the municipalitycontributes for soil conservation and mangrove forest.

The activities developed in the environment have always aroused a double feeling, linked especially to the fact of developing some activity or to conserve the environment. Growing concerns about environmental issues coupled with the dissatisfaction generated by the current system have led to mobilizations in various sectors of society to discuss one of the greatest challenges of today's sustainable development. In order to do so, several meetings were held worldwide, from which came concepts, action plans and demands in search of tools that could make sustainability operational. In this sense, the applications of aggregated index indicators provide guidance, monitoring, evaluation and effective actions towards sustainable development. The present work aims to present and evaluate the Sustainable Development Index (IDS) of the Bragantina Region, through the tool Sustainability Panel - PS, the chosen indicators were based on sustainability indicators published by the Brazilian Institute of Geography and Statistics, IBGE, in the year of 2015. The analysis of the sustainability theme in the Bragantina Region occurred in three scales: the first considering all the municipalities of the Region, the second approaching the Bragança municipality in the years 1991, 2000 and 2010, both verified from the dimension environmental, social, economic and institutional environment according to the PS. The third approach dealt with the environmental perception of the users of the beach of Ajuruteua through the application of questionnaires. The IDS obtained by the PS method for the Bragantina Region, composition by thirteen municipalities, presented a worrying panorama, where only four municipalities obtained positive performances, highlighting the vulnerability of the institutional dimension within the system. For the municipality of Bragança the IDS obtained had a gradual evolution a satisfactory panorama. Through the environmental perception in Ajuruteua it was possible to have a better understanding of the socioeconomic profile of the visitors, the typological classification of the residues generated in the area, besides the reason for this increase and the suggestions to minimize this growth. Therefore, it was perceived that the functionality of the system is complex and the definitions and tools used to conceptualize and quantify sustainability should consider not general knowledge of the system, but rather the impacts generated by different activities in the most varied areas, -relationships of the system across dimensions, verifying their potentialities and vulnerability at different levels and over the years within the system.

The environmental assessment and analysis of the suitability of the occupation permit identification of the most critical areas in the level of degradation is extremely relevant for the establishment of conservation measures, conservation and recovery. This study aimed to conduct an environmental diagnosis of Marine Extractive Reserve of St. John the tip through GIS techniques. Analyses based on information that make up the landscape of CU, especially in the use and occupation of land and the relationships between some aspects considered in the work. The analyzes included aspects related to the use and occupation of land , the region's climate , soil composition and its geomorphology , water resources , fauna and flora , the conditions of life in the communities , the risk of erosion. It was found that the basin water resources are being degraded , the use and land cover still has degraded areas and a process of fragmentation is occurring in the landscape , especially in the vicinity of CU. Potential sources of landscape degradation of mangroves have been identified in the vicinity of the unit , compromising the quality and quantity of the supply of resources . Urbanization is the most influential factor on the CU because it exerts a pressure on the EXRES . Irregular situation with respect to legislation and environmental preservation were detected in the basin . In most of CU along watercourses use and land cover have an advanced stage of regeneration , which refers to the process of occupation of northeastern Paraense . Ecological corridors linking the upland forests are degraded and inadequate , especially for not meeting the environmental function determined by the Forest Code , predominating in these areas pastures . An efficient environmental control policy is needed for these areas, and environmental planning appropriate to guide the occupation surrounding the CU and the adoption of measures for the recovery of the same.

Chikungunya fever (CHIKF) is an arbovirus caused by the Chikungunya virus (CHIKV). Its transmission occurs through the bite of female Aedes aegypti or Aedes albopictus mosquitoes infected with CHIKV. The signs and symptoms of CHIKF are similar to those of dengue, however the main clinical manifestation that differs from it is the involvement of joints such as the joints of the wrists, ankles and elbows causing severe pain inflammation accompanied by swelling, redness and local heat. The objective of this research was to evaluate the influence of income, population density, sanitation and climate variables on CHIKF occurrences. The study was conducted from 2016 to 2018, with application area in the municipality of Belém (PA). The variables were analyzed based on descriptive statistics, from which the mean, standard deviation, coefficient of variation, median, minimum and maximum were determined. The normalities of the variables were tested to define by using parametric or nonparametric correlation tests. Linear regression analysis was performed for variables with statistical significance. Spatial analysis identified the expansion of the disease in the municipality over the period analyzed. As well as outbreaks of high concentration and maintenance of the disease were identified in certain neighborhoods. For socioeconomic variables, Pearson's correlation identified an association between CHIKF and the demographic density variable in 2017, which resulted in a weak but significant linear regression. Significant correlations were identified for indicators of quantity and regularity of water supply, solid waste collection and level of access to sanitation services. While the temperature and precipitation variables in 2016, presented respectively positive and weak association and negative and weak association in relation to CHIKF. The results of this research showed that the urban area of the municipality of Belém (PA), Brazilian Amazon, has significant natural and anthropic elements for the insertion of active transmission foci of Chikungunya fever.

From 1990, the first Conservation Units, which contemplated and favored the presence of traditional populations, were verified in Brazil, a process resulting from the mobilization and struggle of the rubber tappers of the Amazon. Extractive Reserves, specified as a category of sustainable use, initiate the insertion and valorization of traditional knowledge in a regulated and recognized way in the preservation system in Brazil, in spite of that, the economic activities as a source of subsistence Of native flora or artisanal fishery) in the traditional way, and subject to specific regulations (Diegues, 2008). The concept of RESEX was extended until the implantation of territories conserved in coastal zone, covering fishing communities in all extension of the Brazilian coast. With the fishing potential found in the state of Pará (which together with the Maranhão and Amapaan coast, the largest continuous mangrove coast in the world), the creation of RESEX Marinhas in this coastal landscape has increased successively. Between tides, forests, mangroves, rivers, roads, dwellings, squares, ports and other landscapes, artisanal fishermen of RESEX Marinha São João da Ponta, characterize, organize, conceive, structure their territory of daily activities, materializing territorialities and Shaping landscapes. This territory, defined by processes of temporal relations, can not be understood as dissociated from the landscape, since, considering that the landscape "clarifies and humanizes the territory", as is well illustrated by Passos (2013, p.29), it is understood that already It is not enough to analyze the territory, and the respective territorialities that constituted it, without understanding the subjectivity and distinct physical and symbolic elements imbricated to it. It is intended to analyze, in this way, how the landscape territorialized by fishermen is identified by them, and if this identification of their territoriality addresses or can guide paths that conceive the landscape as a "web of relations" that social subjects construct with their territory. In order to interpret the identification of the territorialities of the fishermen it is fundamental to consider the traditional knowledge and their conceptions about the landscape. Therefore, mapping the production sites, which are fishing spots called fishing grounds (where fish species are concentrated in the tide), through participatory mapping, was one of the methodological paths used to interpret the landscape territorialized by artisanal fishermen. This research was carried out in a qualitative approach, developed in the methodology of action research indicated by Thiollent (1996) and aligned with the methodological procedures of field work with semi-directed interviews, participatory mapping with remote sensing image, elaboration of cartographic products with treatment Of information in GIS and geo-photography. The development of this research is significant so that these territories, identified by the fishermen themselves through the marks of the landscape and the paths to which these subjects belong and belong, remain contemplated in the management process, from the elaboration of materials and instruments that continuously Monitoring and protection, for the management and selection of areas of conflict or possible overfishing and consequent impoverishment and / or depletion of exploited resources.

In general, the Brazilian State creates the Conservation Units and Protected Areas to comply with international recommendations and / or local requirements for nature conservation or maintenance of areas where so-called traditional populations live. The Extractive Reserves, Brazilian Units of the sustainable use group, constitute territorial spaces destined to self-sustainable exploitation and conservation of renewable natural resources by traditional populations. In such areas there is the possibility of materializing sustainable development, balancing ecological interests of environmental conservation, as well as the social purposes of improving the lives of the populations that inhabit this territory. The present work aims to identify the elements expressed in the environmental perception of individuals or social groups, that is, to understand the relationships and experiences that promote positive values and attitudes towards the environment, and that are contained in the perception of the inhabitants of these spaces. For this, the Mocapajuba Marine Extractive Reserve was chosen, located in the municipality of São Caetano de Odivelas, in the northeast region of the State of Pará, created in 2014. The methodological procedures were initiated with the literature review for the theoretical discussion on perception Environmental and the relationship with the concepts of place and landscape. Subsequently, through interviews conducted in 2015 and 2016, revealed the elements expressed in the environmental perception of users to understand the relationships and experiences that clarify positive values and attitudes in the face of the Extractive Reserve concept. In this way, the residents expressed environmental perceptions that, in general, are in line with the environmental values deposited in the Conservation Units. Thus, the theoretical and practical information can cooperate for the studies, actions and / or policies to be implemented by the environmental agencies in the PAs, especially in the Marine Extractive

São Caetano de Odivelas is a municipality in the Amazon coastal zone, located in the Microregion of Salgado, in the Northeast of Pará, with the coastline cut by wide recesses or the coast of “rias”, composing a dynamic environment, under which a vast mangrove forest. Recently, the Mocapajuba Extractive Reserve was created in the municipality in 2014. Therefore, this research aimed to evaluate the mangrove areas from driving force, pressure, state, impact and response indicators (PSIR), to provide support to the management of the Conservation Unit. The method chosen was the use of socio environmental indicators, combined with the DPSIR methodology created by the United Nations Environment Program - UNEP, and updated by the Organization for Economic Cooperation and Development - OECD. It was necessary to carry out a systematic review of the literature and conducting on-site visits, in order to assist in monitoring the state and in the analysis of the pressures found in the study area, parallel to this, a classification of the different types of land use was made. in order to identify the anthropic causal activities or sources of pressures and impacts. And the responses obtained through the research of programs and projects at the federal and municipal levels that can solve or mitigate impactful actions. The methodology proved to be satisfactory, as it allowed to infer about the following indicators: Pressure (P) urban expansion, tourist intensity and the absence of sewage treatment; State (E) legally protected area, with high environmental relevance and ecological functions and "in natura" sewage discharge in the Mojuim River; Impact (I), the most significant ones were applied to the model according to the weighting performed. these being: mangrove deforestation, overfishing due to tourism and the effects of waste disposal in inappropriate areas, on the quality of life of the population and the natural environment. The analysis of the answers (R) revealed the Mocapajuba Marine Extractive Reserve (RESEX), since from it it is possible to obtain control over land use, under the domain of the Chico Mendes Institute for Biodiversity Conservation (ICMBio) (federal sphere) ; the guidelines of the Brazilian Forest Code in Areas of Permanent Preservation - APP (MMA), in contrast, the municipal government through investments and public expenses with the purpose of promoting the protection and management of natural resources, such as the promotion of environmental education. Thus, the need for an effective inspection and long-term projects for environmental management, which reconciles use with environmental protection, stands out. Thereby, this work is configured as an important tool, in order to provide subsidies for the elaboration of environmental planning projects and management policies, and actions based on the protection of the mangrove ecosystems.

This study investigates the perception of risk and social vulnerability of the residents of Ajuruteua, a beach located 36 km from the town of Bragança-Pará. Part of this area is considered as a very high risk to marine coastal erosion, as noted by the destruction of properties located by the sea. Erosion is a natural event that affects people’s safety and it is triggered by anthropic factors, especially by disorderly occupation. Due to this the government proposes the evacuation of people from risk areas, because they are vulnerable to erosive action. However, it comes across the economic factor of the families involved, since the income of the people living there depends on the fishing, commerce, houses rental, hostels and other activities developed in the coast. In this perspective, this research aimed to verify residents’ perception on the risk of erosion, as well as to record their adaptation to natural events, and to monitor the impacts of removing the vulnerable population from risk areas to the municipality's headquarters. Such a context brings out the following issues: Can the understanding of the risk perception and social vulnerabilities of people living in Ajuruteua contribute to public policies for disaster risk reduction? The methodology was based on theory and method literature review, documentary research in public and private institutions and the application of a script of interviews with local residents and entrepreneurs. The objective of the interviews was to understand and identify the degree of social vulnerability of the resident population in Ajuruteua from the population 's perception of natural erosion events. It is hoped that the study will be able to contribute to public policies for disaster reduction, collaborating with the discussion about the different perceptions about the appropriate use of natural resources available in Ajuruteua.

Climate change is an issue that, since the last century has gained interest among scientists around the world, there are many information that have been turned to address this issue from different fronts, however, the perception of local communities is far away to be one of the most successful work topics. Brazil has a network of Extractive Reserves (RESEX), which is part of protected natural areas and where environmental managers participate who exercise control, monitoring, implementation of projects that serve as a basis for the conservation of RESEX, as well as a contact direct with local communities. Many mangrove ecosystems are concentrated in the RESEX of the Paraense coast. Around these ecosystems, traditional communities have settled that make use, enjoyment, and enjoyment of them, which have incorporated into their daily activities offered by the mangroves, which ranges from leisure, pleasure, and enjoyment to the generation of income to maintain the lifetime. In this sense, in this work the coastal region of the north of Pará was approached, the so-called Salgado Paraense with the aim of knowing the perception of local actors and the effects of climate change in this territory. To achieve this objective, the work was carried out in two phases. A first study was carried out to find out the amount of published bibliography on the perception of climate change around the world, in three main languages such as Spanish, English and Portuguese. For this bibliographic analysis, we applied natural language and machine learning to analyze more than 30,000 scientific articles. Some maps were produced on study trends, countries with major researchers interested in this topic, the methodologies used, and the approaches taken to understand the effects of climate change. Subsequently, in the second phase, surveys were applied to the environmental managers of the RESEX studied, to know their perception of climate change, interest in the adoption of adaptation strategies in the face of climate change and their perception of the role of the women in social dynamics within RESEX in the face of climate change threats. The findings suggest that studies on the perception of climate change in the coastal communities of northern Pará are necessary and have a lot of potential for their research, since the interested actors really have an affinity in adopting measures against the impacts of climate change, they show their concern about the effects on communities and mangroves, generating an alert and a call to incorporate local populations with more interest in the design and implementation of adequate and pertinent public policies. It is necessary that the actors of organized civil society, community, managers, and governments at different scales understand that the challenges are increasing to face climate change, this situation is worrying in various parts of the world, it is therefore, necessary to incorporate the vision of local communities.

The accelerated and disorderly growth of cities has not been accompanied by the growth and improvement of urban infrastructure, which contribute decisively to the quality of life of its inhabitants. Studies on the urban environment reveal that the urbanization process generates impacts, both environmental and social, however these impacts can be avoided or at least minimized through an effective planning process. For this reason, the great challenge of urban planning bodies is to understand the functioning of the urban environment and provide the right conditions for communities to develop sustainably, seeking a balance between quality of life and preservation of the environment. In this sense, studies that deal with the reality of environmental quality in urban ecosystems are of fundamental importance to support planning policies and more efficient land management. This research aims to evaluate the environmental quality in the urban area of the municipality of Belém / PA, one of the municipalities of the northern region of the country that presents, in population terms, large extensions of subnormal clusters and highlights in the real estate scenario, with characteristics similar to many Brazilian cities. To evaluate the environmental quality, the methodological procedures developed by Borja (1998) and Kawakubo et. al., (2005) were used, using environmental and infrastructure indicators (water supply, sanitary sewage, urban cleaning, flooding, noise pollution and cover (SIPAM, CIOP, SESAN, IBGE, etc.) for the construction of a synthetic index of environmental quality.In order to observe stratifications between the districts, environmental quality charts and basic indexes were developed using Arcgis software. The perception of the residents was also investigated through structured questionnaires whose items correspond to the same indicators selected in the objective data. In order to observe possible contrast between the objective and subjective data an index of environmental perception was constructed using the same methodological precepts for the construction of the objective data and their respective spatialization. The data show that although the results point to a sufficient level of environmental quality, residents are dissatisfied with the infrastructure and quality of the environment.

As a result, the theoretical research problem was presented; Four Dimensions were obtained for the IRC, 'Health and Well-Being', 'Economy and Society', 'Infrastructure and Ecosystems', and 'Leadership and Strategy', with a total of 38 indicators, which allow assessing aspects of resilience of cities. The IRC was operationalized in an Excel spreadsheet and applied in the City of Belém-PA and generated the IRC in the “Good” value. In conclusion, four dimensions and 38 indicators were defined to generate the IRC, and in Belém-PA the IRC was considered “Moderate”, however, in fact, the challenges in working with the theme of urban resilience are still many, and go beyond the conceptual sphere. Although there is still no consensus on the part of specialists in the area regarding the definition of its real meaning, the biggest challenge lies in its operationalization. The process of building systems of resilience indicators is complex and has barriers such as, for example, the lack of data to build indicators to assess some relevant aspects. An example of such indicators, which can be included in future estimates for the city of Belém-PA, are those aimed at measuring infrastructure and ecosystems.

The delimitation of geoenvironmental units enables knowledge of the potential and limitations of the studied physical environment, through the integration of the constituent components of the landscape, pointing out guidelines that minimize and / or avoid negative environmental impacts, subsidizing environmental planning. The objective of this research is to carry out the mapping of the Geoenvironmental Units of the Atalaia Island located in the municipality of Salinópolis PA. This island was chosen because of the significant socio-environmental changes that are currently taking place in this area, which makes it possible to perceive the negative impacts, especially in vulnerable environments, where there are contrasts in the way of using and occupying land, in urban expansion, in agricultural activities and in tourist intensification. In order to arrive at the result of the research, bibliographic surveys, Geoprocessing and remote sensing techniques were used, analysis of satellite images, fieldwork, necessary for the observation in locus and the crossing of the information obtained, which resulted in the map of Geoenvironmental Units. In this way, it was obtained the definition of four homogeneous units according to the potentialities and limitations to the processes of the physical environment and the indiscriminate use of these environments. These units were found from information on secondary materials, essential for the elaboration of the Geoenvironmental zoning proposal of the study area, which serves as a contribution in the elaboration of future plans, as well as for the purposes of rational exploration of natural resources and sustainable use in Atalaia island.

Presentation: Amazonia has an extensive Coastal Zone, with approximately 3,044 km, occupying 35% of the Brazilian coast, with great part of the Orla in different levels of physical vulnerability. Objective: This thesis aims to analyze the physical vulnerability to the action of the sea, the socioenvironmental impacts and related adaptation strategies in the Coastal Zone of the Municipality of Salinópolis, located in the Northern Coast, Pará-Maranhão region of the Amazon Coastal Zone. Methodology: The Orla was subdivided into seven subsectors, according to the Orla Project criteria and physiographic and topographic characteristics. Two general vulnerability indices were determined: Sea Energy Action Vulnerability Index and Sea Level Rise Vulnerability Index (IVC). For the determination of the two indices, the following variables were used: geological, geomorphological, coast slope, topographic dimension, wave height, tidal amplitude, coastline variation, current sea level variation, using time series and future, based on the RCP8.5 scenario of the Intergovernmental Panel on Climate Change. Questionnaires were applied to the population and to the main Municipal Secretariats. The maps were made using orbital images of 1984, 1994, 2000, 2001, 2004, 2015 and 2016, SRTM images and aerial surveying, processed in ArcGis 10.3. Statistical analysis was performed in the Statistical Analysis Software SAS 9.4 program. The socioeconomic data were extracted from the census tracts of the Brazilian Institute of Geography and Statistics, year 2010. Results: five sectors presented Muto Alto indexes and two Moderate to the energy action of the sea. The current vulnerability index to sea level rise showed three sectors of the Lower Bay, two in Moderate and two in High. In the future IVC, five sectors showed Very High, High and Low. In a one-meter elevation sea environment, major environmental systems will be affected, beaches, mangroves, dunes, cliffs, as well as the most vulnerable population will suffer the greatest impacts. The application of the questionnaires showed that the local population can identify the main impacts and has its own adaptation strategies. The municipality does not have in the Master Plan, nor do the secretariats present containment mechanisms, intervention and adaptation of impacts arising from a possible rise in sea level. Conclusion: the high levels of vulnerability of the sea energy action have caused erosion along the coast. The scenario of impacts of sea elevation on the edge of Salinópolis requires the application of efficient public policies to adapt the most socially vulnerable population.

Vulnerabilidade socioambiental relacionada à erosão do solo em Barcarena-PA.
(Universidade Federal do Pará, 2021-02-03) FREITAS, Stephanie Jael Negrão de; PIMENTEL, Márcia Aparecida da Silva; http://lattes.cnpq.br/3994635795557609; https://orcid.org/0000-0001-9893-9777
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.
