A Amazônia ribeirinha e as políticas de desenvolvimento regional: o Baixo Tocantins no contexto da concepção e gestão do Plano Popular de Desenvolvimento Sustentável da Região à Jusante da UHE Tucurui (PPDJUA)
(Universidade Federal do Pará, 2013) COSTA, Gleice Kelly Gonçalves da; LENCIONE, Sandra; http://lattes.cnpq.br/6057522086090435; TRINDADE JÚNIOR, Saint-Clair Cordeiro da; http://lattes.cnpq.br/1762041788112837
The survey consists to establish a relation between regional development and specific characteristics of the region of the lower Tocantins, seeing the participatory planning process developed in that region by the Popular Plan of Sustainable Development of the downstream region of Hydroeletric Plant Tucuruí - PPDJUS. In the context of the mentioned plan, the survey analyses the regional development and management, considering the limits and possibilities of popular participation, the articulation between municipal scales and their consequences on regional scale, and finally, the conception of development proposed in the plan, according to regional particularities. As a methodology to develop this work was used survey and literature review; research and document analysis(PPDJUS, agreements and projects); and semistructured interviews with members of social and union movements, members of the government, members of research institutions and representatives of ELETRONORTE. Became evident that the management model developed in management councils (municipal and regional), created for the definition of investment, represents an advance in face of negotiation process of different social subjects involved(social and union movements, enterprise and government), according to the idea of participatory planning. However, the limits of participation are still evident owing to the restricted participation of a few leaders, institutionalization of social movements and the continuous strong presence of conservative political culture, based on traditional relations. In spite of these fragilities, this development proposal, which considers the environmental variable and proposing projects by the base demands, presents major conditions to fit the regional particularities, as opposed to most recent federal government policies which articulate the region, more focused to the demands of economic development of the international market.

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.

Análise da paisagem na bacia hidrográfica do rio Mocajuba, Nordeste paraense, a partir do modelo teórico GTP
(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.

Análise da qualidade ambiental a partir de indicadores ambientais na área urbana de Paragominas-PA
(Universidade Federal do Pará, 2021-02-22) PEREIRA, Lucimar Costa; ALMEIDA, Arlete Silva de; http://lattes.cnpq.br/1511094180664778
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.

(Universidade Federal do Pará, 2022-08-29) FREITAS, Jaylim Reis de; VELOSO, Gabriel Alves; http://lattes.cnpq.br/9757471213923099; https://orcid.org/0000-0002-3655-4166
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.

Análise das unidades de paisagem da microbacia do igarapé Moura, município de Castanhal (PA): subsídios para o planejamento/ordenamento territorial
(Universidade Federal do Pará, 2013) ALVES, Leonardo Pinheiro; FRANÇA, Carmena Ferreira de; http://lattes.cnpq.br/5723672412810714
This study analyzed the landscape units of the Igarapé Moura micro-basin in the Municipality of Castanhal-PA, considering the structure and dynamics owing to the ability to support anthropogenic actions in order to aid the basin's territorial planning. To carry out this analysis, we have chosen the systemic interpretation method, based on General Systems Theory and the Complex Dynamical Systems Theory. The interpretation script comes from the following operating procedures: an integrated analysis of the physiographic features of the watershed (geology, relief units, hypsometric, slope, soil conditions and ground cover and use), mapping of the landscape structure (landscape units); analysis of the dynamics of landscape units (multitemporal mapping of vegetation cover and land use from satellite images from 1984, 1994 and 2010); delimitation of areas of stability / instability of the physical environment, identifying capable areas for agricultural crops, pasture and forestry, as well as areas unsuitable for agricultural use; delimitation of areas of legal incompatibility, and finally preparing the mapping using the indicated capacity. Based on analysis of the physiographic features of the watershed, it was possible to identify six landscape units: Geosystem of Hills and Law Plateaus with Productive Activities, Geosystems of Law Plateaus and Hills With Urbanized Areas, Geosystems of Low Plateaus with Productive Activities, Geosystem of Low Plateaus with Urbanized Areas, Geosystem of the Capoeiras over Hills, Low Plateaus and Law Plateaus e Geosystem of the Flooded Rainforests in Floodplains. Looking through the instability, the Basin predominantly presents areas with significant levels of instability, especially geosystems that feature human deeds. In contrast, areas with more stable conditions are characterized by areas where is possible to see a denser vegetative substrate, located in the Geosystem of the Capoeiras over Hills, Law Plateaus and Low Plateaus and in Geosystem of the Flooded Rainforests in Floodplains. In the analysis of agricultural suitability of the Basin's landscapes, it was found that its larger portion enables the use of technological development for farming, artificial grazing and forestry. In addition to these, there are also unsuitable areas for agricultural activities. Finally, it was established seven areas of recommended use in accordance with the support capacity of the landscape units of Igarapé Moura Basin: agricultural technology, mechanized agriculture, urban area, preservation, priority preservation, conservation/sustainable use and priority recovery. Therefore, from these analyzes, a need of using technical and scientific levels in agricultural production in the Basin was found, aimed at improving the management of different forms of landscape units and the need of preservation of secondary vegetation cover through techniques aimed at sustainable development linked to forest maintenance, essential for the territorial planning of this area.

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.

Análise de risco a inundação na cidade de Alenquer - Estado do Pará
(Universidade Federal do Pará, 2010-04-23) SILVA JUNIOR, Orleno Marques da; SZLAFSZTEIN, Cláudio Fabian; http://lattes.cnpq.br/1348005678649555
The city of Alenquer, located in the Lower Amazon region of Pará State, historically suffer the threat of flooding. Every year in the flood season, the Surubiú stream increases your level, flooding the lower parts of the city. This thesis analyzes the existing flood risk in the city of Alenquer providing tools for management and improvement of the actions of government. The threat analysis was based on a methodology that combines historical data, hydrology, map building and participatory field work with GPS, identified three distinct areas in the city: (i) high susceptibility area annually affected by floods, is 8,4% of the city area (ii) area of moderate susceptibility, only achieved when the highest rates observed streamflow and (iii) the area that even larger floods is not achieved. The calculation of vulnerability occurred from the construction of an index that includes census data from demographic field work to identify the essential elements and units of responses. After the application of the index found that the 17 sectors of the city, five have high vulnerability, and the other moderate vulnerability. In the risk analysis data vulnerability and threats were integrated and again three areas in the city were identified (i) the high risk area represents 9.45% of the city, where there is high concentration of essential elements and several responses, leading to social and economic damage upon the occurrence of flood (ii) area of moderate risk, 30 % of the city and (iii) low risk zone which corresponds to 60.55% of the city. The Master Plan of the municipality was analyzed with a few questions to verify the inclusion of the theme of threat, vulnerability and risk in this document, after the analysis can conclude the lack of discussion of this theme in the master plan. The results of the research are important for supporting public policies and documents required by the Civil Defense at the time of disasters.

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.

Análise geoambiental da bacia hidrográfica do rio Apeú, nordeste paraense: subsídios ao planejamento ambiental
(Universidade Federal do Pará, 2017-03-16) VALE, Jones Remo Barbosa; BORDALO, Carlos Alexandre Leão; http://lattes.cnpq.br/1253955182585852
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.

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.

The urbanization has been provoking local variations in several climatic elements, among them it a increase of the temperature of the air, provoking the emergence of portions of the space with larger temperatures than the areas to yours spill, that calls her of urban islands of heat. Among the causes of the appearance of the islands of heat, the retreat of the vegetable covering is the most relevant. The purpose of this work was to identify, through the technique of remote sensing, the urban islands of heat and the urban islands of coolness in the continental area of the Municipal district of Belem, as well as the variation of the vegetable covering, comparing the results of the years of 1997 and 2008, in order to reveal a possible relationship between the variation of the vegetable covering and the islands of heat and urban islands of coolness. To develop this research, it was fallen back upon thermal images of sensor TM for determination of the temperature values, as well as data of temperature of the air observed in the stations: climatological conventional of Belem (2o. DISME / INMET), meteorological sinotic of Val-of-Cans and meteorological automatic sinotic of Belem (2o. DISME / INMET). The vegetable covering was also determined with use of the images of sensor TM, with the bands 3,4 and 5. In agreement with the obtained results, it was ended that there was an increase of the urban islands of heat in 2008, mainly in the located neighborhoods in the areas of the Avenue Augusto Montenegro and Highway Arthur Bernardes, and reduction of the islands of coolness in several parts of the continental area of Belem, due to the absence of the vegetable covering, in relation to the year of 1997. It was also possible to identify that in the study area, there was a reduction of the existent vegetable covering in 2008 in comparison with 1997, reduction that that happened mainly in the area that is besides to 1st Patrimonial League of the municipal district of Belem, in the axis understood between the Avenue Augusto Montenegro and the Highway Arthur Bernardes, enlarging the urban area and the increase of the temperature, that it favored the expansion of islands of heat.

The context of complexity, inequality and injustice of the capitalist urban space dates back to the need for a planning and management of this space considering these variables as intrinsic to this model of society, however without accepting them or defend them, having as the ultimate goal the urban development understood as promotion of life quality, social justice and autonomy for all those who produce, reproduce and live the urban space. This planner and manager practice should be perceived as an applied social research, interdisciplinary, covering an effective pipular participation, as well as use their various instruments to assess objectives satisfactorily. Among those instruments is the Cadastro Territorial Multifinalitário (CTM) - Territorial Multipurpose Cadastre, which although not a new idea, having its genesis dated millennia ago, and the current models being very close to those produced in Europe in the nineteenth century, Brazil count only with one "legislation" specifically geared to the CTM dated from the end of the first decade of this century, under an ordinance of the Ministrerio das Cidades - Ministry of Cities, which brought general recommendations about the structure and methodology of implementation of a model of cadastre. While in the local context, in Belém, Pará State Capital City, the production of records dating from the 1970s, and as the current one produced in 2000 as the Cadastro Técnico Multifinalitário.- Tecnical Multipurpose Cadastre. Thus, the present research aims to analyze, with some comparison, the model cadastre models of the Ministry of Cities, proposed in in its decree No. 511/09 - Cadastro Territorial Multifinalitário (CTM) - and the City of Belém Prefecture - called the Cadastro Técnico Multifinalitário, focusing on the issue of the multipurpose considered from the possibility of using the CTM in all spheres of urban planning and management, especially those not directly linked to tax and fiscal spheres, since these are historically the initial concerns of the cadastral record, configuring thus its purpose priority. The work was produced through the use of bibliographic search technique over authors who mainly discuss the concepts of space, territory, urban space, spatial planning, urban planning and management, with collect and analysis of secondary data, conducted through documentary research in official texts of the Ministerio das Cidades about the CTM model for it, its ordinance 511/09 which brought the guidelines of cadastre model, as well as execution reports of the Cadastro Técnico Multifinalitário de Belém and spreadsheets with information about the cadastre, provided by the managing agency of the CTM de Betém. Culminating with semi-structured interviews technique with experts from competent organs to the production and management of the CTM de Belém, as CODEM and SEFIN.

Since 1960, the oriental amazon experimented big transformations thru the changes of regional space organization that the strategies of occupations so on manifested. One important change experimented was the restructuration in the region Urban's net. The new Urban's net that beggined organize themselves didn't removed the importance of tradicionals regional's metropolis: Belém and Manaus, but these metropolis become to survive with regionals centers of the importance growing. The growing of these Regionals Centers become them Able to exercise differents levels of centralities in yours respectives sub-regions. These Urban's spaces have been summoned a lot of studys to define them like medium cities and reflect the implications of these process in the territory. In this context that Macapá since the decade of 1990 rises like a medium city with a growing capacity of exercise centralities in all the amapaense territory and in sub-region north of Marajo. The source in question talks about one qualitative study, having like instrumental, methodological observacion the interview questionary and formulaires. The method of interpretation is based in the historical materialism and dialect. The theoric referencial summoned debates above of the political and economical centralism of macapa in the sub-region north of Marajo: Gurupa and Áfua in detriment of Belém, In period of 1990 to 2015. The work is unfolded in others three objectives that guide the realization of the source: analyze the implication of Macapá like capital of state and city and the political fluxes with Gurupa e Áfua. Identify the principals agents articulate of political and economic fluxes the articulate the political and economical of Macapá in relation to Gurupa and Áfua. The main conclusions show that the condicion of capital state and the medium city of Macapá loads is a factor in the economical and political fluxes in the city rises. There is a centrality of Macapá in the offer of public services and assets basically in the north of the Marajo county Macapá exercises centrality in the fluxes of public services and economicals fluxes in the county of Áfua in relation to Belém city.
