Using the Framework for Evaluation Systems Natural Resources Management Incorporating Sustainability Indicators (MESMIS), a tool used to evaluate the sustainability in family agroecosystems based on the assumptions of systemic approach, this article aims to understand how family agroecosystems adapts to socioeconomic and environmental changes in the Municipality of Curralinho, Marajó, Pará. The locality presents changes in the relations of land tenure; increase in the valuation of non-timber forest products, specially the acai; larger amounts of financial resources for agricultural activities; and technological training courses with a perspective of the insertion of the agroextractivist into the formal market. With theoretical contribution, The MESMIS has been adapted to the local context. Thereby, were constructed ten indicators for sustainability evaluation of 19 family agroecosystems intentionally chosen considering access to policies of land tenure, such as agricultural credit; social compensation; participation in technological capabilities, as well as the author's knowledge about the reality of Boa Esperança community, locus of this research. In agreement with other studies in the Amazon the MESMIS presented different levels of sustainability in family agroecosystems. After a characterization of the family agroecosystems, it was possible to identify two distinct family logics linked to the production of acai: (i) a agroextractivist logic that maintains as a strong element the extraction, more dependent of natural resources and therefore presenting greater co-production, (ii) another agroextractivist logic with greater market integration, with more intensification of technical-productive elements. The different logics may be the reflection of the adaptation of the family agroecosystems to the current socioeconomic context and environment of the region. The logics of the extractive family production go through profound changes.

(Universidade da Amazônia, 2015-12) VIEGAS, Socorro de Fátima Souza da Silva; CABRAL, Eugênia Rosa; GOMES, Sérgio Castro; CARVALHO, André Cutrim
The paper analyzes the actions of an Institution of Higher Education Federal - IFES in relation to the directives of the Environmental Agenda in Public Administration - A3P, which expresses inclusion of environmental issues in management. In response to pressure, the IFES are adhering to the A3P through adoption of sustainable practices. This is a qualitative study, based on desk research and a questionnaire with the managers of the organization. The results show that the adequacy of the IFES A3P is partial, especially regarding the disposal of waste, the use of natural resources and sustainable procurement. Greater coherence between the policies of A3P and the organization’s actions searched was identifi ed in the actions that show quality of life of the servers in the workplace. Despite the low level of congruence between the actions of IFES and the directives of the A3P, the study shows the importance of A3P as a conditioning factor to building a sustainable organization.

This dissertation aims to comprehend how the sustainability narratives about Amazon are configured in Amazônia Viva magazine, an institutional journal that works on sustainability in the relationship between company and society. We also seek to understand the communicative dimension present in this relationship, de symbolic dimension of Amazonian imaginary representation and the aesthetic codes of Amazon’s identification in the visual and written narrative of the magazine. We start from the analysis of the mechanisms of narrative construction about the Amazon from the perspective of the Amazônia Viva magazine, monthly publication, produced and chartered in Pará's newspaper O Liberal, owned by the Rômulo Maiorana Organizations, sponsored by the mining company Vale S/A, The second largest mining company in the world. As theoretical-methodological procedures, we used narrative analysis, with inspiration in the hermeneutic phenomenology proposed by Paul Ricoeur, and methodological procedures based on the seven narrative analysis movements proposed by Motta. As the corpus analysis we selected 14 covers and cover stories, chosen by its level of relation with the sponsoring company and the development of sustainability theme, a way of understanding the construction of institutional narrative in the social context which it is inserted.

This work aims to formalize an engineering protocol containing technical procedures necessary to optimize the consumption of water in the beverage industry, through the evaluation of the potential of water conservation, determination of environmental and economic performance indicators, as well as the proposition of scenarios of water use. In order to explore the opportunities for water conservation, a water balance was carried out with the help of flow measurement methods. Water use analyzes were performed to determine areas and processes where there is significant potential for water savings. Based on the evaluations, investigations, recycling and reuse practices it was observed that the productive sector of the soft drink factory, especially the packaging stage, has the potential to reduce water consumption. The proposed scenarios can provide the company with a reduction in specific water demand from 2.53 to 1.92m³/m³refrigerants, reducing the company's groundwater abstraction by 24.1%. Thus, considering the average production of refrigerants, the daily water savings can be up to 81.4m³, while the company's specific effluent generation can be reduced by 36.7 m³ / d, equivalent to 24, 1% reduction. In addition, the operating costs of the ETE and ETA can be reduced by R$ 39,272.83 per year, representing a savings of 24.5%. Thus, this study proved that water reuse can be successfully implemented in the soft drink industry as a sustainable approach to industrial water management, since the engineering protocol established in this work proved adequate for the collection of information necessary for the control and optimization of water use.

The unrestrained consumption of goods, coupled with population growth, caused a significant increase in the generation of solid waste in Brazil. The search for its correct disposal and sustainability has become an important aspect adopted not only by the private sector, but also by the public. Thus, this study sought to propose the application of Reverse Logistics in the final destination of computer equipment, after the process of disposing of assets at IFAM / CMDI. This research is of a qualitative nature and was used to recognize opinions about this theme, as it gives the respondent freedom to respond and give their own opinion. After analyzing the processes, it was noticed that, when the electronic materials are exchanged, the old ones are placed in a room, with the objective of analyzing which ones can be recovered by the computer team, and then a percentage of 20% a 25% is sent to Campi inland, and the rest is sent to a container and remains there until the entire process of disposing of goods is carried out. Thus, even with the evolution in the use of reverse logistics and consequently in the adaptation of Law No. 12,305 (PNRS), it is concluded that such growth is still not enough in view of the constant evolution of consumption and generation of waste by the Brazilian population.

In recent decades, there have been more debates related to environmental damage that has been causing changes at a global level, according to the understanding of the finitude of natural resources. The Amazon figures as a protagonist when thinking about the protection of the global ecological heritage. Given its importance, the largest tropical forest in the world has been contemplated with several projections to preserve it. Altamira is a municipality in the center of the Legal Amazon and figures as a reflection of the main problems faced in this territory. Traditional populations coexist with agribusiness, and both are flooded by large projects, although one side benefits more. The rural and the urban areas also provide the municipality with a contrast that makes it especially difficult to point out or even define what would be sustainable. Despite the numerous conflicts that do not allow this territory to homogenize, this thesis sought to carry out a socio-environmental analysis based on the axes of human well-being and environmental well-being, of multidisciplinary nature, for the municipality of Altamira, based on the Sustainable Development Goals (SDGs) launched in 2015 by the United Nations Development Program (UNDP) and thus evaluate the main obstacles to the full sustainable development of the municipality. To obtain the results, the methodology used is called the Barometer of Sustainability (BS) and is the result of the major global conventions that debate the courses that take the social, economic, and environmental dimensions. The results obtained showed that Altamira has an intermediate level for sustainability and reflects the need for a special look of the government to the indicators related to the great socio-economic axis as well as the need for the elaboration of strategies to remedy and contain the problems related to the great environmental axis. It was then concluded that the municipality of Altamira is far from achieving the goals established by the 2030 agenda, but that it presents breath and has demonstrated subtle changes that are moving towards achieving such objectives. Finally, although limited, this thesis was intended to date a result and create a basis for future research that aims to analyze, add, or even refute results obtained for the municipality of Altamira.

The decharacterization of tailings has become an extremely relevant and urgent topic in the contemporary global scenario. Given the recent disasters and environmental tragedies resulting from the collapse of mining dams in Brazil in 2015 and 2019, the need to implement efficient and safe processes for the deactivation and recovery of these structures has become imperative. The complexity inherent to this type of enterprise demands a careful and comprehensive approach in evaluating the available options. The simple selection of an alternative based on a single criterion, such as financial cost or deadline, for example, can result in adverse consequences and negative impacts from both a technical, economic, environmental and social point of view. Given the above, this dissertation aims to explore the importance of analyzing alternatives considering multiple criteria in the process of choosing the best solution for the mining dam decharacterization project. Through a literature review and presentation of a case study of the decharacterization of a Manganese dam using the assessment of technical, environmental, economic and socioeconomic requirements as a decisive element in choosing the solution to be detailed. The methodology consists of analyzing the proposed alternative scenarios, including the definition and weighting of the multiple variables to be evaluated. The result obtained demonstrates that the adoption of multiple criteria, which encompass not only economic aspects, but also environmental, social, technical and safety aspects, was fundamental to guarantee a well-informed and sustainable decision. It was evidenced that the analysis of multiple criteria was also able to favor the decision-making process in mining dam decharacterization solutions, facilitating traceability and understanding between the stakeholders involved in projects of this nature.

Caracterização do tecido fibroso de tururi e avaliação de propriedades mecânicas de compósitos de matriz poliéster reforçados com tecido fibroso de tururi
(Universidade Federal do Pará, 2023-01-30) SANTOS, Avener Gleidson Andrade; CÂNDIDO, Verônica Scarpini; http://lattes.cnpq.br/8274665115727809; https://orcid.org/0000-0002-3926-0403
In recent decades, the search for materials with high mechanical performance and that are in accordance with sustainability requirements has become increasing. In the context of sustainability, the United Nations (UN) established in 2015 the Sustainable Development Goals (SDGs), in order to guide the paths to sustainable development. The use of waste to produce new materials is beneficial, because the use of these materials represents a solution for environmentally friendly disposal, thus covering the requirements established by the SDGs. The use of natural fibers in the production of new materials has increased significantly in the last decade. The use of natural fibers as reinforcement in polymer matrix composites is already well established. This is due to the fact that some fibers have high mechanical performance and good thermal stability, two highly attractive properties in composite materials. Composites reinforced with natural fibers have a vast field of application, and can be used in civil construction, aerospace, and automotive industries, among others. In this scenario, the use of tururi fabric as a reinforcement agent in composites of polymeric matrix emerges as a viable alternative for sustainable disposal of this waste coming from the harvesting stage of its fruits. Thus, this study aims to characterize the tururi fibrous tissue by optical microscopy, scanning electron microscopy, X-ray diffraction, thermogravimetric analysis and Fourier transform infrared spectroscopy (FTIR), as well as to determine physical properties such as density, moisture content and weight. The composites were produced using a 2.5, 5.0 and 7.5% by mass percentage of reinforcement. Additionally, tensile, flexural and charpy impact tests were performed. The characterizations revealed that the tururi fibrous tissue is composed of fibers of various diameters and has regions of bifurcation, indicating that the tissue can act in different ways when incorporated as reinforcement. The density, moisture content and weight had average values of 1.17 g/cm3, 16.58% and 146.61 g/m2, respectively. The thermal analysis revealed good thermal stability for the tururi fabric. The mechanical tests pointed out that as the incorporation of reinforcement occurred, the composites tested in traction had a loss of resistance, presenting a loss of 15MPa in relation to the matrix. When requested in flexion the composites reinforced with up to 2.5% showed better mechanical performance, with values of 63.9 MPa. The impact test revealed that the energy absorption capacity increased by 371% compared to the matrix, which indicates that the fabric acted as a good reinforcement agent.

. Caracterização física, aspectos morfológicos, comportamentos térmico e mecânico do pecíolo do miriti como um material potencial para aplicações em pás de turbinas eólicas.
(Universidade Federal do Pará, 2024-10-28) GOMES, Igor dos Santos; VAZ, Jerson Rogério Pinheiro; http://lattes.cnpq.br/1623983294183975; WOOD, David Home
In many small wind turbine blades, the internal space between the laminated shells is filled with a core material. In this context, with the aim of enabling the application in both small and large blades, this thesis presents the petiole of the miriti palm (PMP) as a potential material for such applications. PMP is abundant in the Amazon region, and its harvesting does not harm the palm, as the petiole regrows, making the process fully sustainable. This could play an important role in enhancing the sustainability of wind turbine manufacturing. The physical properties, morphological aspects, and thermal and mechanical behaviors of PMP were determined and compared to balsa wood (BW). Additionally, the advantages of using the easily worked petiole for the core in manufacturing were considered, as demonstrated by the construction of a 0.598 m blade and starting performance tests of the turbine in both computational simulations and wind tunnel experiments. The results showed that PMP is about 50% less dense than BW. Consequently, turbine starting simulations indicated that the low density of the small blade made from PMP reduces starting time by 10% compared to EPS and by 42% compared to BW. While PMP and BW have similar morphological aspects as they are natural materials, BW tends to absorb about 3.6% more moisture and around 9% more water than PMP. The thermal behavior of PMP shows stability up to approximately 200°C, making it suitable for most wind turbine manufacturing processes. Regarding mechanical properties such as tensile, compression, bending, and shear strength, both BW and PMP exhibited elastoplastic behavior. Although BW generally possesses higher mechanical properties than PMP, the specific properties of PMP are greater than those of BW, except in cases where the load application does not align with the vascular bundle direction. For instance, the specific elastic strength and specific elastic modulus in tensile with a load applied at 90° in relation to the vascular bundle and in tensile with a load applied at 0° in relation to the vascular bundle of the PMP are approximately 13.5%, 3%, 30% and 61% higher than those of the BW, respectively. PMP’s specific elastic strength in GS compression is approximately 18.5% higher than BW. In shear strength, the specific elastic strength and specific modulus of elasticity of PMP are 20% and 54.5% higher compared to BW. Fatigue results indicate that PMP has a fatigue life of around 106 cycles. Wind tunnel tests showed that, regardless of wind speed, the best results for power coefficient, torque, and thrust were observed in 6-blade configurations, with values of 0.3083, 0.1224, and 2.2993 for λopt equal to 2.519. In analyzing the experimental results for rotation, thrust, torque, and kinetic energy ratio during turbine starting, the periods through which the turbine transitions between transient and steady states were observed, aligning with literature findings. The results presented in this work show that PMP has potential for application in wind turbine blades, as the combination of sustainable materials with significant specific mechanical properties, such as low density, has the potential to improve turbine design, reduce starting time, and extend the high-efficiency operating range.

The pressure exerted on natural resources, arising from the exponential growth of world demand, leads human activity to an unprecedented scenario. Researchers have been demonstrating numerous efforts for sustainable solutions, in this scenario there is a continuous growth in the development of composite materials with vegetable fibers. In this work, pure orthophthalic polyester matrix materials and composite materials with plant fibers from the babassu coconut epicarp were produced. The composites were manufactured manually using silicone molds. The fibers characterized according to their morphology, through scanning electron microscopy (SEM), were randomly inserted with mass fractions set at 3% and 5%, length varying between 10 mm and 20 mm. The composites produced were analyzed for their mechanical properties, through tensile and flexural tests according to ASTM D 638 and ASTM D 790 standards, and fractographic analysis of the fracture surface through scanning electron microscopy (SEM). The morphological analysis of the surface of the fibers showed its roughness and characteristics present in vegetable fibers. For composites with 3% of fibers, a tensile strength of 20.03 MPa was obtained, while for composites with 5% of fibers, the result was 14.16 MPa. of 32.34 MPa for the composites with 3% of fibers and 37.01 MPa for the composites with 5% of fibers, in both properties (tensile strength and flexural strength) there was a reduction of the same when compared to the matrix material pure. With regard to the modulus of elasticity, the composites had an increase in this mechanical property when compared to the pure matrix, confirming that the increase in the stiffness of the material is due to the increase in the fiber fraction, with the best results obtained in composites with 5 % of fibers, 0.486 GPa in tensile tests and 27.10 GPa in bending tests. The fractographic analyzes of the fracture surfaces showed satisfactory results regarding the identification of failure mechanisms and characteristics present in the composites, such as the presence of air bubbles, voids and the phenomenon of fibers pulled out of the matrix (pull out), indicating low adhesion at the interface matrix/fiber.

The research conducted in the Araí-Peroba Marine Extractive Reserve in Pará aimed to socioeconomically characterize fishing families, assess their financial resilience, and investigate perceptions of fishery management. Data was collected between March and July 2022 in 11 communities, totaling 293 interviews. Data collection was carried out through the Fish Forever Program, implemented by Rare Brazil, using an electronic form that covered topics such as demographics, livelihoods, fishing, resilience, and social capital. The results indicate that artisanal fishing is the primary source of income, accounting for 74.7% of the total family income, but 42.7% of respondents reported a significant decrease in catch over the past two years. The research revealed that the exclusive dependence on fishing exposes communities to socioeconomic risks, especially in the face of environmental and economic variations. The diversification of income sources is identified as an essential strategy to increase economic resilience. Additionally, the research highlighted the division of labor by gender, with men predominating in catching and women in fish processing. Valuing women's roles and promoting gender equality are fundamental to improving the living conditions of communities. The study also highlighted the importance of social capital, showing that mutual trust and cooperation are crucial for sustainable management practices. It is concluded that an integrated and multidimensional approach that values local knowledge, promotes financial inclusion, and strengthens social capital is essential for the sustainable management of fishery resources in the Araí-Peroba Marine Extractive Reserve.

This paper initially provides information about the extraction potential of productive mangroves in the municipalities of Quatipuru and Bragança, as well as the socioeconomic characterization of the extractive professionals (crabbers) of this resource. Parallel to the information generated in the mangroves and communities interviewed in Quatipuru and Bragança, this study also seeks to contextualize the extractive activity of the mangrove crab-uçá around the Pará coast, through information obtained by the collection and analysis of data in different mangrove municipalities of Pará’s coast, characterizing the productive activity of this important resource extraction communities. The information collection occurred in the period between 2010-2012, where the extractive potential was examined, in the mangroves of Bragança and Quatipuru confirming these locations as potentially producing regions, with a density of 5.01 ± 1.09 ind/m2 in the Quatipuru magrove and 6.5 ± 1.0 ind/m2 in the Bragança mangrove with an immediate extraction potential (IEP) of 80.91 % in Quatipuru and 86.23 % in Bragança. Concerning extractive activity in the major communities in the municipalities of Quatipuru and Bragança, the profile of crabbers was characterized by male dominated, low education, with at least 16 years of activity for most in Quatipuru and more than 20 years for most of the interviewed in the communities of Bragança. The primary capture technique used is the "braceamento" with the aid of hook in both locations, where they capture on average 51-100 units / day in Quatipuru and 101-150 in Braganca, where the middleman is the main destination of the product for the sites investigated. The data obtained from the Pará coastal reveal that out of all the mangroves studied, the municipality of Viseu was highlighted as an important forest region of Pará, with a density of 4.23 ± 1.40 ind/m2, CPUE 46.6 (crabs / man / hour) and 226.8 ± 113.1 units captured by crabber/day, however , it is important to notice that this municipality had the lowest average price per crab (R$0.18 ± 0,05) among all communities of the municipalities visited. The importance of this resource for the communities in the coastal Pará is clear and requires regulatory actions that support exploration with sustainability, as well as encouraging these professionals of artisanal fisheries through actions of to recover their citizenship.

Certifications focused on sustainability are a series of practices that can help improve the quality of life of traditional populations in the Amazon, by providing advantages such as the use of sustainable agricultural production methods, increased productivity, reduced socioenvironmental impact, management forestry that helps conserve biodiversity and generate income. The general objective of the research was to analyze how sustainability certifications are being implemented with community organizations in the Amazon, using the cumaru almond and açaí fruit production chains as a case study. The hypothesis that motivated the research was the following: the implementation of sustainability certifications brings benefits to community organizations, which can result in a better quality of life for traditional populations in the Amazon, compared to those that do not adopt any standards. The results indicate that the benefits can be perceived in dimensions such as: Quality Management; Handler Management; Environmental management; Risk management. The use of certifications with community organizations is recommended, as long as other development models are equally recognized and respected, encouraging the promotion of inclusive and sustainable Amazon sociobiodiversity chains. It is noteworthy that it is possible that the benefits identified in community organizations that adopt some sustainability standard are related to other factors, linked to the historical and regional context, which may have resulted in more evident advances in some communities than in others.
