Acordo de pesca do Rio Caeté, Bragança, Pará: análise do processo de construção
(Universidade Federal do Pará, 2024-03-25) TAVARES, Mayra Patrícia Corrêa; OLIVEIRA, Marcelo do Vale; http://lattes.cnpq.br/2841179890845657; https://orcid.org/0000-0001-6047-939X; BARBOZA, Roberta Sá Leitão; http://lattes.cnpq.br/9331256487699477; https://orcid.org/0000-0003-2367-553X
This research was developed from September 2019 to February 2023. The construction of this work was made by a bibliographic review about the theme: fishing agreements in the Amazon, use of common resource and territory, besides direct observation, semi structured interviews, use of participatory techniques (problem tree, participatory mapping, historical matrix) and analysis of collected data. According to demands of the riverside dweller communities on the Caeté River about improper fishing in the estuarine area and apprehension of fishing material, it was observed how the implementation process of the fishing agreement of Caeté River begun, such as it was analyzed several conflicts that occurred between the social actor in the space of the river that were narrated by the fishermen and community dwellers. Based on bibliographic research, the bragantina region is the first to develop a fishing agreement in the coastal region of Caeté, northeast of Pará. The fishing agreement of Caeté River is focused on at least 20 communities on the middle of Caeté River, situated on the bragantina coastal plain, northeast of Pará. The research aimed to comprehend the construction process of the fishing agreement of middle Caeté River in Bragança, Pará, analyzing the conflicts between the subject users of the space. By means of the collected data, it was determined that the conflicts of the local social groups with external fishermen and Public Bodies complicated the control and maintenance of fishing territories in the studied area. External and local fishermen introduced fishing practices that are considered “improper” by the communities as well as by environmental inspection agencies, causing several conflicts between them and the Municipal Inspection Agencies. Thus, it was possible to imply that the management rules locally established by the municipal secretariat of aquaculture and fishing of the city of Bragança together the fishermen showed an effective scenario in the maintenance of fishing stocks. Whereas that, it is noted that the agreement is an instrument of participative management, conditioning the access of a responsible way to natural resources of the estuarine where the traditional populations of the Caeté River live.

Agostinho de Souza Moreira, comandante dos rios Guamá e Capim: trajetória de uma liderança cabana do interior da Amazônia (1829-1837)
(Universidade Federal do Pará, 2024-03-14) NASCIMENTO, Wesley David Silva do; RICCI, Magda Maria de Oliveira; http://lattes.cnpq.br/4368326880097299
This dissertation analyzes the trajectory of Agostinho de Souza Moreira, a leader from the interior of Grão-Pará in the early years of Cabanagem (1835-1836). Through the research around this subject, this work aims to address the unfolding of the hut war in the Capim and Guamá rivers, which comprises the parishes of São Domingos da Boa Vista and São Miguel da Cachoeira, and the village of Ourém; in addition to exerting influence in the town of Bragança and in the place of Viseu. In these locations, Agostinho Moreira acted as General Commander with the responsibility of legitimizing the authority of the cabano government in the region. Previously, this guy had stints in the City Council, the Ordinary Court and the National Guard, which allowed him to meet many people, the supervision of the region's production, in addition to the local geography. Historically marked by escapes, by the action of the mocambos, indigenous resistance and military desertions, this region known as the middle of the road between Pará and Maranhão was convulsed in many struggles led by these peoples, who fought for better living conditions and their freedoms, during the 1820s. Thus, from 1836 onwards, when Cabanagem began to radicalize to the interior of Pará, Agostinho Moreira secured notoriety for having control of a region that held the necessary goods for a war economy that threatened the control of the interprovincial authorities who armed themselves heavily in the hunt for the cabano leader. In this sense, we will present the region of Agostinho Moreira's activity marked by crossings and refuges. And then we will analyze his trajectory in search of a place in local power until his rise as a cabano leader, highlighting his organization, his war strategies and his escapes during the anticabana repression. We did this through the search for documentary traces that would lead us to Agostinho Moreira found in letters and correspondence exchanged between authorities, terms of council, and newspaper reports that circulated in the Empire, using the methodology of the indiciary paradigm to identify the action of the amocambados and indigenous people in the period of greatest radicality of the Cabana war.

Agressão por morcegos em humanos em uma área de conservação na Amazônia Oriental
(Universidade Federal do Pará, 2020-10-27) LIMA, Ana Paula de Lima e; FERNANDES, José Guilherme dos Santos; http://lattes.cnpq.br/7023812449790431; https://orcid.org/0000-0001-9946-4961; BEZERRA, Isis Abel; http://lattes.cnpq.br/3274919406647242
Bat attacks on humans have been reported in the municipality of Curuçá, precisely around and within the Mãe Grande Extractive Reserve. This work aims to understand the space-time perception and the dynamics of aggressions by blood-sucking bats in humans in an extractive reserve area in the Amazon. As a methodological procedure, documentary and article references were collected. Oral interviews were also conducted with the oldest social actors and with individuals who had already been attacked from the communities visited. Individuals who confirmed that they had been assaulted by bats were georeferenced. The most affected are artisanal fishermen who live with their families or stay for seasons on the islands and beaches to fish for crab, fish or shrimp. In general, the interviewees do not relate the alteration of the landscape to the increase in aggressions, but they highlight the reduction of some animal species in this environment. However, it was possible to identify locations where aggressions have not occurred for at least 10 years associated with the introduction of electrical energy. In locations where there is no electricity, individuals with recent attacks have been identified. In the fishermen's perception, alcoholism is an important factor for the exposure of these individuals. It identifies the need for educational work for the population that is attacked, and the recognition of public policies for those individuals who become more vulnerable to bats.

The Organic agriculture has been stimulated by the social movements of the region in which it operates this study, as an alternative able to corroborate the consolidation strategies more sustainable agroecosystems. Understanding organic agriculture as a production system based on relations more harmonized with the environment and provides greater equity and profitability, it was proposed to analyze the folding of organic production in the sustainability of familiar agroecosystems in the municipality of Medicilândia, state of Pará. We had as central hypothesis that organic production provides positive repercussions on the sustainability of the agroecosystems. Therefore, it was decided by methodological arrangement with qualitative procedures such as field observation and interviews with producers members COPOAM - Cooperative of Organic Farmers of the Amazon and quantitative procedures, mostly with the adjustment tool MESMIS (Framework for Evaluation of Systems of Natural Resource Management incorporating sustainabilities indicators) to the reality of family farmers of Medicilândia. With the sustainability evaluation of agroecosystems was established that there is the folding of organic production in the agroecosystems studied, incurring changes in production dynamics well as the way of life of families.

Agrobiodiversidade e conhecimentos locais das plantas alimentícias no quilombo de Deus Ajude, Arquipélago do Marajó – Pará
(Universidade Federal do Pará, 2020-09-08) BEZERRA, Sueyla Malcher; SABLAYROLLES, Maria das Graças Pires; http://lattes.cnpq.br/0250972497887101; SILVA, Luis Mauro Santos; http://lattes.cnpq.br/7285459738695923
In this study, we seek to analyze the traditional knowledge and practices associated with agrobiodiversity of food plants, as well as the constitution of sovereignty and food autonomy in the production of two non Quilombo of Deus Ajude, Salvaterra, Pará state, Brazil. For the development of the research, we used a qualitative and quantitative approach. Regarding the methodological procedure, we opted for the case study, participant observation, non-directive identification, questionnaires, free lists, collection and identification of botanical material. Data analysis was carried out by systematizing information collected and by the vertical and horizontal analysis of interviews, data triangulation and Cognitive Salience Index. Results showed that the traditional knowledge of the Quilombola community regarding plant foods is constituted through their daily relationship between the community and nature, as well as through the continuous exchange of knowledge between different generations. Amazonian seasonality has revealed itself as a regulator of the plurality of productive activities throughout the year, and these are carried out through a symbiotic relationship, where both nature and the Quilombo are sustained. In addition, the representative foods of the Marajoara Quilombo, such as beiju, cação, tiborna, cunhapira and crueira, become one of the ways of maintaining the Quilombo's agrobiodiversity. On the other hand, the limitations of access to the territory of common use, the impositions of the farmes around the Quilombo, and the influences of capitalist market that promote changes in the way food is obtained and on the eating habits of quilombolas are evident. Therefore, the valorization of Quilombola culture and its way of life becomes an ally for the preservation of traditional knowledge and practices, as well as the managed of agrobiodiversity.

Alegorias do sofrimento e da resistência: disposições afetivas da política em imagens fotográficas
(Associação Nacional dos Programas de Pós-Graduação em Comunicação, 2022-06) LAGE, Leandro Rodrigues
The purpose of the text is to present the general lines of an epistemological and also a methodological proposal for the debate on images, considered affective expressions of indignation, conviction and desire. It seeks to examine photographs of the artistic and photojournalistic regimes as allegories of the suffering and resistance of the Amazonian peoples, with the intention of discussing how these images manage and give visible and sensitive expression to experiences of suffering, to physiognomies of historical time, to survivals of the desire and political subjectivations. This proposal starts from the experimentalism of knowledge through allegories, rehearsing the theoretical-methodological productivity of the benjaminian allegorical episteme in the legibility of the images and tensioning the forms, correspondences, temporalities and conventions in the examination of images that offer an apprehension of history as an anachrony of sufferings and fights. The background to this approach is the inextricable link between image and politics.

The year 2020 was marked by the beginning of the COVID-19 pandemic and the increase in deforestation and fires in Brazilian Amazon. Data from Inpe (2020) recorded 10,312, 88 km2 of consolidated deforestation in the region, in addition to 103,161 outbreaks of fires during that year. Months of August and September were the ones with the highest rate of fires and the states of Pará, Mato Grosso and Amazonas accounted for 70% of deforestation. Meanwhile, "the herd passed" [a figure of speech refering to Ricardo Salles speech] with the approval of 593 acts by the federal government related to changes in rules on environmental protection in Brazil (OBSERVATÓRIO DO CLIMA, 2021). Amid the health, political and environmental crisis, journalism played an important role in providing information to population (CASERO-RIPOLLÉS, 2020). In this context, this research analyzes how was the coverage on deforestation and burning in two of the main news portals of the North region of the country: “O Liberal.com – PA” and “A Crítica – AM”, during the month of September 2020, considering the pandemic period and its adversities. The main theoretical and methodological framework chosen was the Critical Discourse Analysis - CDA (FAIRCLOUGH, 2001). Through the analysis of the newspapers it can be concluded that Jair Bolsonaro government, in the midst of the COVID-19 pandemic, managed to occupy a privileged space in the publications, with a speech aimed at alleviating the problems in the Amazon and widely reproduced by the two newspapers without significant counterpoints. Justifications that attributed deforestation and burning to the climate itself in Amazon and to agricultural activities traditionally carried out by rural, indigenous and quilombola communities were used. In addition, the credibility of scientific data on the subject disclosed by institutions such as the National Institute for Space Research - INPE was questioned.

A Amazônia e o desenvolvimento: aspectos da trajetória das políticas públicas na região
(Universidad de Salamanca, 2020) SILVA, Maria Dolores Lima da
This article makes an assessment of public development policies that were planned for the Amazon since the 1950s and materialized, especially from the 1970s onwards. Encouraged economic exploitation did not result in a significant increase in the social well-being of the population. As the foundation for this argument, bibliographic studies and research on the websites of public institutions and non-governmental organizations are used. The records of researchers and entities working in the region show that traditional populations suffer from the disruption of their ways of life and that the conflicts generated extend over decades, remaining unsolved.

Bibliometric analysis of the dissertations defended in the postgraduate program in sustainable development of the moist tropic (PPGDSTU) and the postgraduate program in natural resource management and local development in the Amazon (PPGEDAM) at the Federal University of Pará. It aims to identify the main research currents linked to the access of natural resources. The research is characterized as quantitative, descriptive and bibliometric, from the survey of the dissertations in the online portals of the programs (PPGDSTU and PPGEDAM), Institutional Repository of UFPA (Riufpa), and on the Curriculum Lattes Platform. The year of defense analysis, research themes and more productive researchers were selected, presenting the main research strands and offering a "state of the art" in the scientific production of PPGDSTU and PPGEDAM. It was used as research tools: a) The software VOSviewer to identify the main thematic trends of postgraduate programs analyzed; b) The Wordclouds.com software in order to elaborate clouds of keywords, aiming at mapping the most used terms and discussed in the analyzed dissertations, and c) The Software Gephi to view the scientific collaboration network between teachers and tasks of the programs. The first year of defense of each program was adopted until 2018. It was found that so PPGEDAM as PPGDSTU have 172 dissertations produced between 2009 to 2018 while PPGDSTU / NAEA has 254 dissertations between 1987 to 2018 and, as for teachers which more guided in the PPGDSTU, 39 guiders were counted, while in PPGEDAM, has 27. It is concluded that research carried out in these programs through the natural resources theme in the Amazon, have been contributing to a more sustainable and predatory planet of predatory actions. It is also suggested the stimulus of collaborative partnerships between programs, creating academic master's incentives at PPGEDAM and Professional Master in PPGDSTU, in which it will contribute to the increase in the productivity of the institution. It is also suggested the implementation of research fueling scholarships to improve the performance of the programs, thus avoiding the oscillation of scientific productivity.

The use of remote sensing in reservoir sediment monitoring is important for temporal spac knowledge of sediment deposition in dam structures. In this context, this research was developed in the hydrographic basin that covers the Tucuruí HOU reservoir, in which suspended sediment concentration data from the M1 monitoring station located at 2 km upstream of the dam were acquired, and were integrated into the analyses to understand the relationship between the responses of satellite images and field measurements. Sediment analyses were performed with 14-year time series of MODIS images, composed of 8 days. Surface reflectance estimates were calculated using simplinear regression and coefficient of determination (R2). For the use and occupation of the land of the hydrographic basin, a temporal analysis of Landsat-5, Landsat-8 OLI/TIRS images was performed. Next, the land use and occupation were related to water quality analyses of stations upstream 1 (M1), Amount Repartimento (MR) and Montante Pacurui (MP). The results show that the calibration curve generated the linear regression equation with good fit for MI monitoring station, presenting efficiency in the data estimated by reflectance through this model. The analyses of land use and occupation show that over the years there was a reduction in forest formation and at the same time pasture growth occurred. In relation to water quality, the impacts caused by anthropic actions have negative influences. Thus, it is possible to observe the relevance of the use of remote sensing techniques, geoprocessing and geotechnologies, as instruments that help in the planning of land use and occupation, in the analysis of water quality and management of water resources in reservoir regions, since these technologies enable greater spatial scope of the analyses with lower costs.

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

The Amazonian scenario is diverse, where ways of life, as well as its quality, are directly related to environmental and social interactions. From the analysis of the indicators used in the Amazon Social Progress Index and Pastoral da Criança and considering the high degree of subjectivity that comprises Quality of Life, it would be possible to develop a methodology to measure these indexes aimed at the Amazonian social sphere that address the quality of life? The objective is to understand the quality of life in Amazonian municipalities through indicators that portray developments based on social performances such as the Amazon Social Progress Index and the Pastoral da Criança. The data analysis methodology will be carried out in two ways: firstly through the Knowledge Discovery in Databases (KDD) process originating from data from Pastoral da Criança and the second will be based on the Systematic Mapping of the Social Progress Index (IPS) of the Amazon based on the PICOC methodology (P: population/patients; I: intervention; C: comparison/control; O: result; C: context). Research and databases, bibliographic review, study and selection of productions, characterization, study and monitoring in the field and comparative report between these were carried out. With regard to the results obtained, it is noted that IPS Amazônia, in its latest reports, did little to address the traditional peoples who inhabit the corresponding area, as well as the periodicity of its publications. Pastoral da Criança, on the other hand, does not operate in the environmental area and excludes other audiences from its support other than pregnant women, babies and children up to 6 years of age. It is noteworthy that both sources of research and QoL activities benefit, but do not completely meet the needs of the region, providing a basis to guide public policy planning and actions aimed at the Amazon.

Soures's coastal plain, eastern Marajó island (Pará), is formed by muddy and sandy deposits, low gradient areas submitted to tidal and wave processes. The morphological features are tidal flats, estuaries, tidal channels and barrier-beach ridges . The faciological and stratigraphical analysis of six vibra-core with medium deph of four meters and from outcrops allowed a caracterization of depositional environments, temporal sequence and spacial corelation, the elaboration of stratigraphical seccions and column. Were identified five facies associations: (1) tidal flat facies, (2) mangrove facies, (3) tidal channel bar facies, (4) beach facies and (5) dune facies. The sedimentary history of the Soure coastal plain is represented by two stratigraphical successions: (1) progradational succession (tidal flat, mangrove and channel bar facies association) and (2) retrogradational succession (beach and dune facies association). These successions are related to a expansion phase of tidal flats and mangroves with progradation of the coastline (Middle/Late Holocene) and a posterior retrogradation phase with landward migration of the shoreline (Late Holocene). The depositional history of the Soure coastal plain is related to the holocenic evolution model of the northeast coastal plains of Pará.

Leprosy is a millenarian contagious disease, with chronic and stigmatizing characteristics, from the remotest times of humanity until today. It is characterized as a disease of the poor and Brazil is the second country in the world with the highest incidence. The lack of public policies aimed at reducing poverty through the improvement of socio-economic factors in the country is directly related to the incidence of the disease in Brazil. Strategies for control and monitoring should follow intelligent actions. One of the solutions for monitoring the disease is the use of Bayesian networks as a probabilistic method for taking decisions on both the control and the procedures to adopt in order to reduce the incidence of the disease. The objective of the present study is to analyse the association of leprosy incidence in relation to indicators of human development, habitation and income level, considering the Brazilian Amazon region in relation to the entire country. An ecological study, based on data obtained on cases of leprosy in Brazil for the year 2010, obtained from the Information System of Hardship Notifications (SINAN) through the Informatics Department of the National Health Service (DATASUS) and the socio-economic indicators found in the Demographic Census Research database of the Brazilian Institute for Geographical and Statistical Survey – IBGE, as well as information from the Municipal Human Development Index, regarding education and income, obtained from the website of the Human Development Atlas of Brazil, also for the year 2010. The methodology combined data mining with the analysis of spatial distribution. The Bayesian network technique was used aimed at measuring the association between variables of the domain of the problem as well as to establish the analogy of the data between the municipalities under study with data for all other Brazilian municipalities. Applying the algorithm K2 relevant associations were found for the following indicators applied in the investigation: Brazilian Legal Amazon, Municipal Human Development Index of Income and Education and Household Housing Condition. Using the Bayesian network model adopted, there is a significant association between the percentage of homes with more than 2 inhabitants and the rate of incidence of leprosy. Although the relationship between the rate of incidence, socio-economic factors (no water supply, no toilet, poverty and overcrowding of the home), low educational indices and income has already been reported in several studies, the insertion of the indicators that considers population density of the home was a novel proposition of the present study and the indicators of greatest most significance of this investigation. The analysis of leprosy incidence with respect to spatial distribution, comparing the Amazon region with the entire country, revealed that public policies for habitation in the studied region were almost non-existent, since the population density of homes is very high, facilitating the appearance of contagious diseases such as leprosy.

Background: There has been a revolution in the treatment of Chronic Myeloid Leukemia since imatinib's introduction. However, patient adherence has a great impact on the response obtained with medical treatment. This study's objective was to analyze the drug adherence and the factors that influenced it in patients with Chronic Myeloid Leukemia in a referral hospital in the Brazilian Amazon. Method: This was a retrospective study including 120 patients with Chronic Myeloid Leukemia from January 2002 to December 2014. The adherence was estimated by the Proportion of Days Covered and the persistence by Kaplan-Meier analysis. The data was analyzed in Epi Info 7® software and the relationship between the variables was analyzed by Fisher's exact test. A p-value lower than 0.05 was considered significant. Results: Twenty-seven patients (22.5%) were considered non-adherent. There has been irregular medication use and disinterest in the treatment in 20.83% (n = 25), of which 13 were considered non-adherent (p < 0.001). A total of 26.67% (n = 32) abandoned the treatment for a period. Of those, 56.25% (n = 18) were non-adherent (p < 0.001). Distance to the hospital, lack of medication and side-effects were all non-significant to low adherence. At the end of a 360-day follow-up, 44.16% (n = 53) of patients presented a break in persistence, whose average was 255 days. Conclusion: The adherence found in this study was similar to that found in others of its kind. The only factors that negatively influenced the adherence were disinterest and abandonment of treatment, which can reflect the need to individually educate Chronic Myeloid Leukemia patients.

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.

Aplicabilidade de um sistema de baixo custo para o monitoramento de dados meteoceanográficos na zona costeira Amazônica
(Universidade Federal do Pará, 2025-04-23) SOTÃO, Daniel da Silva; ROSÁRIO, Renan Peixoto; http://lattes.cnpq.br/8003860457518342; https://orcid.org/0000-0003-2913-0514
This study aimed to develop, implement, and validate a low-cost Continuous Monitoring Prototype (CMP) to collect meteoceanographic data in the Amazon Coastal Zone (ACZ), a region vulnerable to climate change and lacking environmental data. The system, built with an ESP32 microcontroller, integrates sensors for air temperature and relative humidity (HDC1080 and AM2302), atmospheric pressure (BMP280 and MS5611), water temperature (DS18B20), tide level (HC-SR04), precipitation, and wind speed and direction. Sensor validation was performed by comparing the collected data with reference equipment: a CICLUS PRO weather station (CWS) and a Sonlist Levelogger 5 LTC recorder (CTDlog). The CMP conducted four joint test campaigns with the CWS and CTDlog, totaling 56,221 records. Linear regression was applied to develop calibration equations for each sensor. Calibration quality was assessed using the coefficient of determination (R²), root mean square error (RMSE), Pearson correlation coefficient, and residual analysis. The HDC1080 and AM2302 sensors showed excellent performance for temperature measurement, with R² > 0.9, RMSE < 0.2 °C, mean absolute residual (MAE) < 0.12 °C, and very strong Pearson correlation (r ≥ 0.9). However, they exhibited instability in relative humidity measurements (R² ≈ 0.64; RMSE ≈ 3.46%; MAE ≈ 2.52%). The performance of the BMP280 and MS5611 pressure sensors was initially affected by internal heating, but after thermal compensation, they achieved R² values between 0.88 and 0.99, RMSE from 0.17 to 0.45 hPa, and MAE from 0.11 to 0.34 hPa, with the BMP280 showing superior performance. The DS18B20 water temperature sensor showed very strong correlation, with R² ≈ 0.94, RMSE ≈ 0.036 °C, and MAE ≈ 0.021 °C, proving highly promising. The HCSR04 sensor stood out as the most accurate, with R² ≈ 0.99, RMSE ≈ 2.6 cm, and MAE ≈ 1.9 cm. Precipitation and wind sensors presented inconsistencies and require further testing. The total production cost of the CMP was BRL 952.75, representing savings of 86.19% compared to the CWS (BRL 6,897.00) and 96.14% compared to the CTDlog (BRL 24,677.29). When compared to equivalent equipment, the CMP achieved at least 66.33% cost reduction compared to basic stations and 87.3% compared to lower-cost temperature and water level recorders. The CMP proved to be a viable, economical, and replicable solution for continuous environmental monitoring in the ACZ, with the potential to fill existing gaps in observation networks, although improvements are still needed to enhance its long-term performance.

O aplicativo alerta clima indígena: digitalização das terras indígenas à luz da ecologia da comunicação
(Universidade Federal do Pará, 2021-11-17) RAYOL, Clarissa da Silva; COSTA, Luciana Miranda
This dissertation aims to analyze, in the light of the ecology of communication, the digitization of Indigenous Lands experienced by the Alerta Clima Indígena application, developed by Ipam together with the Raoni Institute, Indigenous of Roraima (CIR) and the Commission of Chiefs and Leaders of the Araribóia Indigenous Land (CCOCALITIA), whose purpose is to disseminate scientific data on climate, fire and deforestation of Indigenous Lands in the Brazilian Amazon. The platform also has resources for creating alerts against threats to Indigenous Lands and inserting information about traditional uses such as hunting, fishing and gathering. In this context, based on ecology of communication (DI FELICE, 2017), this characterization is an experimental and qualitative research context of the immersive perspective in which the researcher enters the networks and integrates as supplying all in das. In the investigative path, we present a description of the app's partner associations and the collaborative construction of indigenous workshops while, later, we immerse ourselves in the app's interactive architectures and then analyze the independent processes experienced by the Mẽbêngôkôkókre (Kayapó) people, from the perspective of two residents of the Capoto/Jarina Indigenous Land located in the state of Mato Grosso. In this sense, the experience of digitization, of Indigenous Lands, from the Alerta Clima Indígena app in the “creation of hybrid worlds” (DI FELICE, 2021), where scientific data, technologies, rains, wind, animals and how trees have their own capabilities and are transformed by them, as well as indigenous peoples and creativity in the forms of appropriation of the invention from the new practices for the Management of Indigenous Lands.

The Brazilian Amazon has about 69% of available freshwater in Brazil, an amount which ends up creating the illusion that no lack of water and not lacking in the region, the large supply of this resource becomes a problem when it comes to the Management and Planning Water Resources in the Amazon, according to the wasteful use and lack of maintenance of stocks, compounded by the release of untreated wastewater. Speaking of water conservation programs in the Amazon a few decades ago and still today, with less intensity, is somewhat strange, given the large amount of water available and the culture of abundance. But with climate change associated with the water crisis in the century XXI and the growth of environmental awareness, a new paradigm for water use. Thus, this research discusses the importance of the use of rainwater for non-potable purposes, since the potential for exploitation, throughout the year, due to this high rainfall in the Amazon region, ranging, on average, 119.6 mm in months from November to 441.6 mm in March. It was verified the potential utilization of rainwater from the areas of the roofs of some buildings, located at the Federal University of Pará - UFPA, Campus Guamá, also known as City University Professor José da Silveira Netto. The methods used for sizing of the reservoir were the Rippl and Interactive, and economic viability checking done by the methods of Net Present Value - NPV and discounted payback. As a result, there was obtained by the method of Rippl a volume exceeding 1000 m³, while the interactive method was a maximum of 75 m³. The economic viability presented fragile as a function of time to return exceed the useful life of the utilization system for rain water.
