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.

The rapid growth and the lack of policies for city planning provoke changes that affect the quality of life of the population. In this perspective, the analysis of environmental quality arises from the need to improve urban environmental conditions. Given this, the present research had as general objective, to evaluate the urban environmental quality in the city of Paragominas-PA, in the mesoregion of the southeast of Para. For this, the methodology developed by Vasques (2017) was adapted, based on objective analysis, using a system of urban environmental indicators, being the same, Water supply; Sewage collection and treatment; Household solid urban waste collection; Selective collection of solid waste; Flooded areas; Vegetable cover and free spaces. The procedures followed: definition of indicators and data collection; application of quantitative indices and spatial representation of each indicator and subsequent assessment and diagnosis of environmental quality. Inhabited blocks of the urban area were used as the spatial unit of analysis. Data analysis indicated that the entire study area has a water supply, provided by the Paragominas Sanitation Agency. Only 0.37 km² (3.04%) of the city are served by sewage collection and treatment services, restricted to condominiums and residences. The household waste collection is carried out in the entire urban area, while the selective collection mainly covers the central area and the nearby subdivisions, totaling 6.30 km² (51.90%) of the inhabited spaces. 1.85 km² (15.24%) of the inhabited spaces have already been affected by flooding in Paragominas. The data for vegetation cover showed a percentage of 15.43%. Data analysis indicated that 4.35 km² (35.83%) of inhabited places have public free spaces up to 300 m. The diagnosis of environmental quality showed that 77.31% (9.38 km²) of the urban area of Paragominas was classified as “intermediate environmental quality”, 19.20% (2.33 km²) as “best environmental quality” and 3.49% (0.42 km²) as “worst environmental quality”. The result had direct interference from the sewage collection and treatment indicator and the spatial distribution of free spaces, also influenced by vegetation cover. Considering the approaches carried out in this research, it is necessary to emphasize the need for urban planning by integrating social and environmental elements, so that the problems that affect the quality of urban life are remedied or minimized.

The overall objective of this study is to analyze the environmental vulnerability of the Jaurucu sub-basin and to understand how land cover and land use changes between 1990 and 2020 affect the loss of its landscape potential and its geoecological and socioeconomic features, including the pattern of encroachment of environmental systems. . , possibilities and limits of use and the impact on spatial changes. To achieve the desired goals, the theoretical and methodological foundations of the earth system approach, the theory of ecological dynamics, the concepts of landscape, land system and stability of the environmental system were chosen; The concepts of risk and vulnerability were introduced to avoid confusion when understanding these concepts. The research used techniques and methodological procedures as theoretical and methodological support for mapping environmental systems, assumptions by Bertrand (2004), Sotchava (1977), Tricart (1977), Monteiro (2000), Souza (2000) and others. The cartographic products were created with the support of geographic information systems (GIS). The environmental vulnerability analysis was adapted by applying the methodology of Crepani et al. proposed method. Persons. (2001), Grigio (2003), Tagliani (2003), Costa et al. (2006), Oliveira and Mattos (2014), based on Tricart (1977). Field work has been performed to verify the generation of land cover and land cover maps using MapaBiomas, vulnerability determinations are calculated using the grid calculation tool from algebraic equations crossing data in the GIS environment. Therefore, creating a sustainable development plan requires planning and analysis of the environment. Understanding vulnerable environments and the systems used within them helps with territory planning.

The “Metrópole da Amazônia” Wildlife Refuge Conservation Unit is a large environmental preservation area located in the 11th largest metropolitan region in the country, with an estimated population of over 2 million inhabitants. With immense natural riches, it can be considered the last frontier of urban expansion in the region. The work used landscape geoecology to identify the degree of impact of the geoecological units and the Leopold Matrix, one of the tools used in environmental impact assessment, was used to measure the environmental impacts of the study area. The result was that, within the area of the conservation unit, the two geoecological units described in the study (Tablelands and Plains) are well preserved, but the most impacted was the Tablelands, especially found in the REVIS buffer zone. Finally, proposals were suggested to be analyzed and implemented by the unit's management body in order to mitigate the existing impacts in the study area.

The performance of agents producing urban space in Altamira has gone through several phases, from the opening of the trans-Amazonian highway (BR-230) in the 1970s to the construction of the Belo Monte Hydroelectric Power Plant complex in the early 2011s. contributed significantly to the population density of the region, producing urban spaces driven by real estate speculation and real estate producing agents, especially production by subdivisions that contributed to the current configuration of the urban fabric, densifying new areas and creating new peripheries, marked by discontinuity. and low occupancy density. In this way, the present research aims to analyze the dynamics of the expansion of urban space in Altamira-PA from the perspective of real estate development with the advent of the Belo Monte hydroelectric complex, highlighting the location of urban land subdivisions, infrastructure urban areas, housing densities, urban control and regulation instruments and in addition to the socio environmental reflexes related to these activities. The methodological procedure adopted to carry out this research can be divided into the Pre-Field stages with a bibliographic and documentary survey on various concepts related to urbanization, urban space, promoters, real estate sector, urban expansion and land subdivision, in addition to data consultation and information in Official Bodies and Institutions; Field, with in loco verification of points to verify the current state of the most deficient land subdivisions of basic infrastructure in the city of Altamira; and the Post-Field (analytical/comparative), consolidating the information collected in the form of graphs, tables, charts and cartographic representations, in addition to discussions and propositions on the theme of the dynamics of urban expansion conducted by land subdivision projects in the area of urban perimeter of Altamira. It was found that the real estate production in Altamira has contributed to the configuration of a fragmented urban reality from a spatial point of view, characterized by aspects of continuity and densification and discontinuity and sprawl, with the location of many projects in areas far from the urban core. main feature, a reality that has become the standard that characterizes the urban fabric of the Altamira headquarters.

Análise espacial de unidades de paisagem do município de Quatipuru – Pará
(Universidade Federal do Pará, 2017-08-04) BARBOSA JÚNIOR, João Silva; MORAES, Sérgio Cardoso de; http://lattes.cnpq.br/4568311568729454
Different uses of natural resources of the coastal landscape generate impacts that need to be known and studied. As far as the coastal zone is concerned, there is an aggravating factor, since it is formed by highly specialized, productive and ecologically and economically important environments. In addition, it has a high degree of urbanization and consequently a high settlement rate. The National Coastal Management Plan applied to the Amazonian coastal zone has operated in an incipient way, since there is still no political articulation between the municipalities involved and the other spheres of power, lack of a base of information and methodologies based on local experiences, which ensure the proper execution of the plan. However, other strategies on the knowledge of the coastal environments were executed, based on regional and national research edicts, applied to the municipality of Quatipuru, ensuring a good information base, which were useful for the purposes of this dissertation, which aimed at mapping the landscape units of the municipality of Quatipuru, Pará, which today has become a conservation unit, RESEX Marine category, with the monitoring and participation of public hearings. In this way, it is understood that it is a separation of the coastal landscape into homogeneous areas, denominated "landscape units", covers an analysis and treatment of data without the right to products of Landscape Ecology, through Remote Sensing with an application of computational programs of object oriented classification in Geographic Information Systems, generating specialization and even an understanding of landscape formation processes are not filters of geographic analysis. For the better definition and delimitation of landscape units, the vegetation unit was chosen as an essential element because it is the result of the dominant ecological processes in the coastal zone. In this way, a physiographic matrix was generated that aided the mapping by identifying two geomorphological units of regional expression: 1) the Lower Coastal Plateau, which is formed by secondary vegetation or capoeira in different stages of regeneration. Of particular note are the urban areas, formed by dense human occupation, including the municipal headquarters - Quatipuru and the community of Boa Vista, and other traditional communities, thus forming diverse groups of family farmers, fishermen, crabmen, that uses the secondary vegetation and the field areas with cattle and buffalo management differently. The sandy Coastal Plain is integrated by the restinga, in contact with the Atlantic Ocean, while the 3) Lamosa Plain is dominated by mangroves and saline fields. Note: 4) Alluvial plain with quite impacted floodplain forests by the removal of vegetation cover. In addition to these mapped units, paleorestingas bands with old and successive coastlines were identified in the interior of the mangrove, up to the present sandy range. Besides this, it was identified that each mapped unit has spatial relations of connectivity, adjacency and delimitation, with the adjacent unit, concomitantly. Such relationships spatially demonstrate the interactions of the ecological and anthropic processes that form the coastal landscape. Thus, the mangrove stands out as the largest and most important landscape unit, because it has a spatial relation with all other units, the flooded, saline or freshwater fields are always bordering the mangrove. The contribution of the research will mainly be to guide management and governance actions within the Marine Quatipuru-Primavera RESEX, combined with the elaboration of the municipal territorial planning plan.

The hydrographic basin of the Apeú river is located in the northeastern region of Pará, more precisely in the metropolitan mesoregion of Belém, it covers the municipalities of Castanhal, Santa Izabel do Pará and Inhangapí. The Apeú river basin presents itself as an important area for observation of the processes of landscape transformation, because this unit, during the last thirty years, underwent significant transformations, imposed by the dynamics of land use. This basin presents rural and urban characteristics, in this area there are socials and environmental problems, resulting from the absence or deficiency of public services. The main factors that contribute to the degradation of the basin are: the waterproofing of the soil, resulting from the urban expansion; lack of erosion control; removal of land cover for land use purposes; contamination and silting of the water courses. Given this context, this dissertation has the objective to provide subsidies to the environmental planning of this hydrographic basin. The methodology adopted in this research was developed by Rodriguez (1994) and Rodriguez et al. (1995), adapted to environmental planning by Leal (1995), this methodology contains the following steps: Inventory, Diagnosis and Proposals. The research was based on data and information about the physical environment, the dynamics of land use and vegetation cover, environmental legislation, social and economic information. The obtained results demonstrate that the landscape of the Apeú river basin has undergone a progressive process of transformation, due to the anthropic interference, resulting in different social and environmental problems, unaccompanied by effective policies of environmental planning and territorial ordening. The proposals presented aim to subsidize the environmental planning of the basin that should be a joint and organic initiative of the three municipalities that cover it.

Although the Amazon Biome has an incalculable value for the balance and maintenance of life on the planet, in recent years it has suffered from the construction of controversial infrastructure works, in particular the opening of highways and construction of hydroelectric plants, such as the BR-230 Highway (Transamazônica) and the Belo Monte Hydroelectric Power Plant, as happened in the Xingu River hydrographic basin, which caused and can still entail several modifications at different spatial scales, mainly at the local level. Therefore, it is extremely important to understand the functioning of these landscapes and their tendencies towards changes arising from human activities, thus providing subsidies to plan environmentally sustainable uses. Adopting the concept of hydrographic basins as a physical-territorial unit for measuring socio-environmental impacts and the geoecology of landscapes as a methodology for systemic environmental analysis, this research aims to study the operation and changes caused by the opening of the Transamazon Highway and its construction of the Belo Monte Hydroelectric Complex in the Igarapé Ambé hydrographic sub-basin which has its territorial extension cut by the aforementioned highway and is located within the Direct Influence Area (AID) and the Directly Affected Area (ADA) of the Belo Monte Hydroelectric Complex and that drain the urban area of the city of Altamira in the State of Pará. The analyzes show that 45% of the SBHA's landscapes are with active morphogenetic processes and 29% are with moderate environmental vulnerability and in a fragile stage of ecodynamic balance, which shows the importance of thinking about alternative uses for these landscapes.

Análise integrada da paisagem e processos de erosão costeira na ilha de Atalaia, Salinópolis, Pará
(Universidade Federal do Pará, 2024-03-27) SOUZA, Ewerton Müller da Silva; ANDRADE, Milena Marília Nogueira de; http://lattes.cnpq.br/1930321094483005; https://orcid.org/0000-0001-5799-7321
The study aims to analyze the landscape and erosion susceptibility processes on Atalaia Island, Salinópolis, Pará, as a basis for coastal management policies. The objective unfolds in examining the coastline position between 2002 and 2022, identifying coastal dynamics through geoindicators, analyzing landscape units, and the degree of susceptibility to erosion on the island. To achieve the objectives, the study area was divided into three sectors: Espadarte, Atalaia, and Sofia. The materials and methods used include satellite images for a twenty-year multi-temporal analysis, with polygon change analysis techniques, areal and linear rates. For this assessment of coastal changes, the Digital Shoreline Analysis System (DSAS) plugin was used in the Geographic Information System environment of ArcMap 10.5. The use of geoindicators was granted through field sheets with the identification of natural or anthropogenic elements that pointed to the movement of the coastline. For the landscape analysis, the theoretical basis of landscape geoecology and the use of geoprocessing to generate a map of landscape units were used. The study revealed areas of high susceptibility with 47,798m², mainly in sector A, in this sector, geoindicators such as the front strip of vegetation modified by erosion (44) and the presence of retaining walls and other constructions in contact with the beach arch or on the surface of estirance (64) stand out. The areas of moderate susceptibility were present, prominently in Sector B, with an area of 66,950m², in this sector, the geoindicators of water/sewage piping or energy poles, located on the beach arch in a situation of destruction by physical agents (54) and the presence of retaining walls and other constructions in contact with the beach arch or on the surface of estirance (62) stand out. The areas of low susceptibility to erosion were present, most evidently, in Sector C, with an area of 341,274.1m², in this sector, the geoindicator related to the width of the post-beach/sandy berm surface (70) stands out. The results of the landscape analysis allowed the understanding of the structure and functioning of the fluvio-marine plain, urban areas, open areas, moving dunes, and beach and post-beach. The investigation offers a dynamic perspective on the erosion processes of Atalaia Island from the employed methodology, thereby, the results indicate the need for more effective coastal management strategies, underlining the importance of an integrated approach that considers both physical and socioeconomic aspects to mitigate adverse impacts on local communities and the ecosystem.

Análises das paisagens da ilha de Cotijuba: através do mapeamento das unidades geoambientais, Belém/PA
(Universidade Federal do Pará, 2021-02-21) SILVA, Elias Klelington Leocádio Rodrigues da; ALMEIDA, Arlete Silva de; http://lattes.cnpq.br/1511094180664778
The present research looks at the Cotijuba Island, Belém / PA, located in the island region of the municipality of Belém. The study turns to the geoenvironmental theme from the integrated analysis of the landscape. The choice of this study area is justified, because in the last decades Cotijuba has undergone a rampant urbanization process, with irrational use of its resources, generating deforestation for the extraction of wood and removal of sand for civil construction. Thus, we sought to map the geoenvironmental units of Cotijuba Island, based on a survey of the elements that make up the landscape. The methodology followed the following steps: Bibliographic survey that enabled the survey of concepts that were guiding factors for the development of the research, Field study that allowed the survey of data and analyzes that are only possible with the measurement in loco, and Laboratory study that was essential to the development of the research, using techniques of remote sensing and geoprocessing that linked to the GIS allowed the making of all cartographic products presented in the research. For the mapping of land use and land cover classes, the Envi 5.1 software was used for supervised classification, extracting a Kappa index of 0.96. For the study of landscape metrics of forest fragments, the software arcgis 10.1 was used from the extension Partch Analyzes. In both procedures, the Sentinel-2 satellite image from the year 2018 was used. For the production of the MDEs, the Alos Palsar radar image was used, which allowed the analysis of the island's altimetry and slope. The mapping of the variables: geology, geomorphology and pedology, were carried out using information collected in the field and analysis of the results obtained from the products made in the Sentinel-2 and Alos Palsar image, based on Florenzano's remote sensing techniques methodology ( 2007). In view of this, the mapping of the Five Geoenvironmental Units of Cotijuba Island was made, highlighting their general characteristics. The results showed that Cotijuba needs a Management and Management plan on a municipal scale aimed at conserving natural resources and promoting the generation of jobs and income for the local community. In this sense, it is expected that the products raised here will serve as subsidies for them. Thus, ecotourism and the implementation of ecological corridors are suggested as measures to mitigate the problems presented here.

Antropoceno na Amazônia: holoceno em curso ou prelúdio de uma nova época geológica do homem?

The Natural Domains of the Brazilian Amazon present a high biogeographic diversity, favored by the complex geological substratum and equatorial climate, both predominant in the Amazonian landscape, located in the northern portion of Brazil, covering an area equivalent to 40% of the national territory (~3.7 million Km2). Human expansion in the Amazon has produced a series of transformations in its natural resources. In this sense, this work aimed to perform a retrospective on the trajectory of human beings in the Amazonian domains, through the spatialization of anthropogenic evidences and analysis of anthropogenic indicators, likely to be associated with precepts of the Anthropocene, made possible by a geographical perspective. The analysis raised the aspects of both morphoclimatic and phytogeographic domains, highlighting their dominant landscapes and natural systems, through biophysical compartmentalization, working as a substrate in the analysis of the dynamics of socio-spatial events and the materialized evidences of human action in the landscapes, under a broad temporal spectrum - the Holocene. The research was based on a holistic and integrative approach of variables, related to both natural and socio-spatial aspects, from a systemic vision, aimed at sizing and measuring the patterns of use of natural resources, the anthropogenization degree of natural domains and the proposition of anthropogenic landscapes/structures. In this sense, the research revealed that these domains currently present a very significant anthropogenic percentage of approximately 70%, the result of a broad and diverse socio-spatial dynamic, which attributed to the region a marked variability of human macrosystems and semi-natural landscapes embedded in apparently natural ecosystems. However, it was detected that this estimate is probably underestimated, if we consider the evidence, according to a cumulative perspective, reaching a value around 150%, that is, 50% above the total area of the study, which denounces a high anthropogenic pressure in the region. Given the above, and considering the Anthropocene precepts, centered on the anthropogenic conception, it is suggested that the Amazon region contains anthropogenic landscapes, substantially altered, for at least four thousand years AP, when much of its domains were already occupied and significantly used and managed by human groups.

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.

This research analyzed the process of removal of poor communities from Altamira who lived in the floodplain areas of the Altamira, Ambé and Panelas streams, to Collective Urban Settlements (RUC) in outlying areas. The study is based on the installation of the Belo Monte hydroelectric plant in Altamira and the re-urbanization of the central areas, which, among other factors, culminated in the removal of thousands of families, changing the entire dynamic of their lives. Our main objective is to demonstrate that the process of planned removals of the residents of the baixões is constituted as socio-spatial segregation. In this way, we present elements that prove the idea raised. The methodology used was qualitative research where we sought, through semi-structured interviews with residents, to identify elements that prove socio-spatial segregation. The results of this study showed that the residents are dissatisfied with the change of their homes, mainly due to the mobility factor, and that the distance from the central areas caused other problems such as unemployment, increased poverty, violence, low quality of education, health problems, social isolation, loss of affective ties with neighbors and family, loss of identity with the river, among other social and psychological problems. Thus, this research proves the initial thesis.

The Legal Amazon, which encompasses a vast area of tropical forest, has been deeply affected by economic and political dynamics since the mid-twentieth century. In this context, this study aims to understand the urban dynamics of the city of Brasil Novo, considering its unique characteristics as a small city in the Amazon. The socio-spatial formation of the city is understood to have resulted from policies aimed at developing and integrating the Brazilian Amazon into the national economy. The method used to analyze the processes shaping Brasil Novo is historical and dialectical materialism, which supports interpretations based on the periodization of the city’s spatial phenomena to explain its reality. The following methodological procedures were employed: a) documentary and bibliographic research; b) secondary data collection; c) administration of surveys in the city’s commercial sector; and d) administration of surveys in residential neighborhoods. The research revealed that Brasil Novo, which emerged with the construction of the BR-230 highway, exhibits socio-spatial dynamics marked by strong integration between rural and urban areas, driven by agricultural production and the actions of various social and economic agents. The highway plays a central role in connecting the city to external markets and integrating it into the regional urban network. Additionally, it was observed that the neighborhoods of Centro, Cidade Alta, and Jardim Valadares display distinct socioeconomic dynamics, reflecting the productive and social transformations that have occurred over time.

This research aims to understand the urban economy of a riverside city in the Amazon, in light of the theory of spatial circuits of the urban economy - the upper and lower circuit, proposed by Milton Santos in 1970. The locus of this research is the city of Porto de Moz/PA, located in the Lower Xingu (mesoregion of the Lower Amazon), at the confluence of the Xingu River and the Amazon River. The focus of the research analysis is to understand, through the theory of circuits, the urban economy of a riverside city, considering that the small riverside cities of the Amazon present peculiarities regarding their formation, the relationship with the river, and traditional ways of life. Thus, the dynamics and elements of these cities differ from other regions, as many emerged during colonization in the Amazon and through developmental projects in the region. In this sense, the riverside cities of the Amazon present a lower and traditional economy, it is hypothesized that the city of Porto de Moz is based on a lower economy that contributes directly and indirectly to the local economy. Through the realization of field research through (photographic/aerial records, application of forms with commercial agents, in addition to cartographic mapping), it was found that the city of Porto de Moz presents more elements and characteristics of the lower circuit and the marginal upper circuit, since the city aggregates different economic agents, such as fishermen, street vendors, hawkers, etc., these local agents contribute significantly to the local and regional economy of the city, as it establishes economic relations with the other municipalities in the region around it, and also, has economic relations with the RESEX, which is part of the territory.

The objective of this research is to analyse the contribution of the urban and peri-urban agriculture in the local development of the municipality of Marituba-PA. Thus, the methodology presented a qualitative and quantitative character based on visits to agricultural parcels (direct observation), meetings with farmers and semi-structured interviews. Then, we used GPS map 62s and drone phantom 4 for location of agricultural areas and aerial photography. In summary, the results of our theoretical discussion on the concepts of Territory, Territoriality and Power allows us to conclude that there are all related to geography and respect human spatiality and also present in other areas of knowledge, each with a focus on a certain perspective. Likewise, he started the two circuits of the urban economy: the inferior circuit as the superior circuit do not articulate in the same way because there are different. The two circuits complete each other while remaining different from each other. Certainly, the results obtained demonstrate that urban and peri-urban agriculture contribute significantly to food security and income generation, as well as the local development of the Uriboca neighborhood. In addition, farmers are mostly people with low education and agriculture and their main activity. Therefore, decision-makers should develop public policies that will encourage this activity to generate more profits for the weel-being of Marituba residents.

Da patrimonialização global ao patrimônio-territorial amazônico: a singularidade da Feira do Ver-o-Peso em Belém do Pará
(Universidade Federal do Pará, 2023-05-31) GONÇALVES, Sabrina Forte e Silva; COSTA, Everaldo Batista da Costa; http://lattes.cnpq.br/6223294904658578; HTTPS://ORCID.ORG/0000-0003-0734-6680; TAVARES, Maria Goretti da Costa; http://lattes.cnpq.br/7796891525258446
The object of this research is the Ver-o-Peso Fair, located in the city of Belém do Pará, as a popularly activated territorial heritage. That is, it intends to understand the fair as a territory where sociocultural practices and popular memorials, ancestral knowledge and doings, maintained by subjects historically subalternized by the processes of territorial formation in Latin America, resist; and to investigate what risks this heritage-territory faces in the face of urbanization, especially the processes of global patrimonialization. The following objectives are proposed: to identify and analyze which elements and practices of Amazonian culture give notoriety to the Ver-o-Peso Fair, as a popularly activated territorial heritage facing risks in the face of the global patrimonialization process; to identify who are the subjects that activate and how the popular activation of the territorial heritage of the Ver-o-Peso Fair is constituted; and to identify which risks the territorial heritage faces in the face of global patrimonialization. Thus, we start from the dialectical relationship between the urban economy, global patrimonialization and activated territorial heritage, to investigate the fair from the problem-questions: Which elements and practices of the Amazonian culture consecrate the Ver-o-Peso Fair as a popularly activated territorial heritage, facing risks in the face of the global patrimonialization process? And more specific questions, such as: Who are the subjects that activate the territorial heritage of the Ver-o-Peso Fair and resist the processes of global patrimonialization? How is the popular activation of the territorial heritage of the Ver-o-Peso Fair, faced with the process of global patrimonialization? What are the risks faced by the popular cultural elements and practices that make Feira do Ver-o-Peso a territorial heritage in face of global patrimonialization? The geographical approach to the research is guided by the historical-dialectical materialist method, starting from the inter-scalar dimension of the universal – particular – singular movement of contemporary urbanization, in order to understand how the mechanisms of global patrimonialization are particularized in the Central Area of Belém and land on a social fact represented by a territory appropriated secularly by sociocultural relations. In this way, the cultural dimension of the territory is privileged, whose thesis is based on the perspective of heritage utopisms, as a theoretical-methodological proposal focused on the Latin American reality, seeking to understand the spatial contradictions and social vulnerabilities generated by the universal Eurocentric logic of global urbanization/patrimonialization particularized in the Ver-o-Peso Fair. And at the same time, capture elements and values of spatial order that activate and highlight the Fair as a territory guardian of memories and ancestral social and cultural practices. The research found that heritage utopianisms are already underway at the fair, ratifying the thesis that: the Ver-o-Peso fair is an Amazonian heritage-territory popularly activated and fundamental for the maintenance of ancestral life, from the metropolis. It is represented by the singularities of handicrafts, herbs and medicinal remedies, typical spices such as Maniva and Tucupi, and Afro-religious elements and practices. However, it is impacted by contemporary urbanization mechanisms, such as: urban requalification projects and heritage policies aimed at the tourist market, which trigger risks of re-signification and loss of identity. Thus, the thesis brings a contribution to the debate of the contradictions linked to heritage, to rethink new proposals for preservation, from the existential perspective of the subjects that compose it.

Das águas para a cidade e da cidade pelas águas: mudanças e permanências em Maracanã/PA, uma cidade ribeirinha-costeira do Salgado Paraense
(Universidade Federal do Pará, 2024-02-07) COSTA, Valter Pinheiro da; AMARAL, Márcio Douglas Brito; http://lattes.cnpq.br/6997234298024427
This research has as its theme: The city-river relationship and the Amazon coastal space. The object of analysis is: the production of urban space based on the city-river relationship and the coastal space. The locus is Maracanã/PA, a city of ancient colonization in the Salgado Paraense egion, which has had its dynamics altered over time by different processes of territorial modernization. It is an urban center linked to the river-floodplain-forest pattern of spatial organization (Gonçalves, 2015), with economic dynamics linked to the past and to the river-sea routes, revealing the city's articulation with a temporality not fully assimilated by the activities and ways of life recently implemented. In view of this, the question is: how has the production of urban space occurred in the city of Maracanã, considering the dialectic of riverside socio-spatial changes and permanences, intrinsic to the city-river relationship and the coastal space, in the face of the territorial dynamics derived from the action of the State and the interests of capital? The main objective is to analyze socio-spatial changes and continuities manifested in the relationship between the city of Maracanã and the river and coastal space, in light of the territorial dynamics of roads, fishing modernization, tourism and Conservation Units (UC). The main hypothesis is that, in the process of coexistence of intra-urban socio-spatial changes and permanences, the riverside-coastal dynamics of Maracanã/PA continue to produce a space of resistance with Amazonian characteristics typical of the dynamics that the city establishes as the river and the coastal space. This occurs even in the face of the transformative territorial modernization that advances due to the action of the State and the interests of capital, such as the opening of the branch known as “Old Road” and the PA-127; projects arising from the modernization of fishing, such as the fires at the Industrial Fishing Complex in the Itacoã neighborhood, beach tourism and the Maracanã Extractive Reserve Conservation Unit. The method of analysis used was the Regressive-Progressive. The methodological procedures applied were: literature review, document analysis, field research, photographic records, open interviews, application of forms and cartographic representations. The basic theory used the social production of space from the Lefebvrian perspective, as well as its application to studies of regional “urban diversity” (Trindade Jr., 2010, p. 235) with qualitative research techniques. As a result, the hypothesis initially proposed was proven. Thus, the city of Maracanã continues to produce a space of resistance with the presence of a “riverside” or way of life characteristic of the people who live on the banks of Amazonian water sources (Rente Neto and Furtado, 2015, p. 159), typical of the dynamics that the city establishes with the river and the coastal space. Thus, the Maracanã River in the coastal space continues to have great socioeconomic and cultural importance, although the city currently has a bimodal transportation system, with the road being the most used route. Therefore, Maracanã continues to maintain a Strong relationship with the river, manifesting characteristics of an authentic riverside-coastal city, due to its location on the riverbank in the coastal space, its historical genesis related to the first colonization process in the Amazon, its strong relationship with its immediate surroundings and the region, its values, daily habits and economic dynamics linked to traditional activities such as artisanal fishing.

De seringueiro a ribeirinho: um estudo de caso sobre a reprodução do modo de vida beiradeiro na comunidade Bela Vista, reserva extrativista rio Xingu
(Universidade Federal do Pará, 2021-08-23) TORRES, Maria Augusta Martins Rodrigues; NAHUM, João Santos; http://lattes.cnpq.br/9009465125001273
This dissertation is a case study on the reproduction of the beiradeiro (riverine) way of life in the middle Xingu river region. The study analyzes three aspects of the way of life that produced this place, from its origin to the present day. The former Belo Horizonte seringal (rubber state), more than 300km distant from Altamira's town, in the state of Pará, was inhabited by non-indigenous migrants since the last years of the 19th century. Today, in this same space, there are riverine families living in the Bela Vista community, which since 2008 has been part of the Rio Xingu Extractive Reserve. The study shows how beiradeiro’s way of life has been reproduced in this place, the dynamics of the use of space, the work involved in the support of families and the social relations existing in the place, comparatively in the “time of the seringais” and in the “community time”.

Desenvolvimento turístico na Amazônia: uma análise socioespacial fundada nos circuitos da economia urbana em Salinópolis, Pará
(Universidade Federal do Pará, 2020-08-24) SILVA, Cleber Gomes da; TAVARES, Maria Goretti da Costa; http://lattes.cnpq.br/7796891525258446
Observing the characteristic differences in income and technological modernization common to underdeveloped countries, present in the Amazonian context, one defends the thesis that the socio-spatial organization of Salinópolis in Pará can be analyzed as a result of a dialectic relationship between the two circuits of the urban economy, constituted in the process of tourism development. This dynamic can be evidenced to some extent by differences in tourist flows; in labor relations; in organization, technology and spatial distribution of firms. In general terms, it presents itself as an alternative to grasp the implications of tourism praxis in urban space. Due to the multiple possibilities of approach on the subject and the need to overcome more economical conceptions, an alternative of critical analysis is sought that has scope in the local reality. For this purpose, a case study was carried out in the municipality of Salinópolis in the state of Pará, made possible by documentary, bibliographic research, interviews and georeferencing of areas appropriate for tourism in the urban space. Representatives of 100 tourist firms were interviewed, specifically from the lodging facilities and restaurants; 100 residents and 200 tourists. Based on the organization of these data, the thesis was organized, in addition to the introduction and conclusion in three more chapters. In the first chapter, the theoretical approaches of the thesis are discussed and in the second, the role of tourism in the socio-spatial formation of the city is described. The third chapter highlights the relationship between tourism development in the production of urban economy circuits, demonstrated from the results of the field research. Concludes that there is a coexistence of two tourism circuits in the urban economy, responsible for inequalities in socio-spatial organization The results of the analysis can directly contribute to the formulation of proposals for policies, projects and research that allow the emergence of tourism reproduction alternatives capable of contemplating the interests of society at the local scale.
