Avaliação da sustentabilidade de agroecossistemas familiares agroextrativistas de açaizeiros na região das ilhas do município de Cametá, Pará
(Universidade Federal do Pará, 2013-05-10) BATISTA, Katharine Tavares; SANTANA, Antônio Cordeiro de; http://lattes.cnpq.br/2532279040491194; LEMOS, Walkymário de Paulo; http://lattes.cnpq.br/6841621785311887
The choice of research theme due to the importance that the fruit açai, Euterpe oleracea Mart. represents in the socioeconomics of the Cametá population, mainly the riverside residents, as well asthe concernabout possible changes in the production systems in the agroecosystems of açaí floodplains due to the growing demand for the fruit. Thus, this research aimed to assess to the socioeconomic and environmental sustainability of agroecosystems family who manage açaí in the region of the islands of the municipality of Cametá, Pará. That research was conducted in 52 agroecosystems family, distributed in 19 river islands, between the months of August to December 2012, considering 2011, the year of the crop of the fruit açaí. The agroecosystems were characterized into five dimensions of sustainability: general aspects, social, economic, technological and environmental and later identified the determinants of sustainability (profitability; total cost of production and location of agroecosystems), through exploratory factor analysis, and the similarities observed between the agroecosystems grouped using the technique of the dendrogram (Cluster analysis). When comparing the current state of sustainability of agroecosystems family in the Islands region of Cametá and correlate the açai management adopted, was found that, the most sustainable agroecosystems, considered in descending order, present rural incomes higher than non income rural and adopt management techniques from agricultural researches.

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

Expansão urbana da Região Metropolitana de Belém sob a ótica de um sistema de índices de sustentabilidade
(Universidade Federal do Pará, 2016-09) VIEIRA, Ima Célia Guimarães; PEREIRA, Fabiana da Silva
The metropolitan area of Belém (RMB) contains 1/3 of the population of Pará State, Brazil, and its recent expansion has caused a number of social and environmental problems that undermine access to infrastructure and services and also impact other factors that influence urban sustainability. In recent years, various methodologies for assessing the sustainability of cities have been proposed, but the challenges of incorporating a multidimensional approach in the evaluation of urban sustainability are still enormous. In this work, we applied the Urban Sustainability Index System (SISU) to the RMB in order to analyze the levels of sustainability of the municipalities that constitute this metropolitan area and to verify the limitations and challenges in applying this method of measurement in the Amazon region. Seven indicators were used for the environmental quality index (IQA), and four for the political institutional capacity index (ICP) and the municipal human development index (IDHM). The results show that there is little variation in the IQA and IHDM indices, and the least-populated municipalities such as Santa Barbara and Benevides have better IQAs, while larger-populated municipalities, such as Belém and Ananindeua, have better IDHMs. However, it is in relation to ICP that this metropolitan area has the highest inequality, thus reflecting the need for the institutional and political empowerment of this region.

Processos de modificação e a sustentabilidade de agroecossistemas familiares em comunidade de várzea do Município de Cametá - PA
(Universidade Federal do Pará, 2012) RESQUE, Antonio Gabriel Lima; SILVA, Luis Mauro Santos; http://lattes.cnpq.br/7285459738695923; https://orcid.org/0000-0003-1311-1271
This research identified and evaluated the processes of change in Family agroecosystems located in the Baixo Tocantins territory’s township of Cameta, PA, from the influence of external interventions (local development initiatives and rural credit), emphasizing the system diversity as a point that promotes the multidimensional sustainability of these agroecosystems. The methodology used was based on the Indicator-based Framework for Evaluation of Natural Resource Management Systems (MESMIS). The research was carried out in várzea areas of Cametá Township, on the first semester of 2012. The geographic and empiric locus was the Caripi community. Using a table containing 11 indicators of sustainability (1 simple and 10 composed) adjusted to the local reality including the environmental, social and technical-economical dimensions, 11 agroecosystems were evaluated. The data gathering tools used were questionnaire(s), semi-structured guide(s), field notebooks and participant observation. The field research involved the participation of the local actors in the data gathering steps. The field results showed, among the list of indicators proposed, some of them that were most important to the reality of Baixo Tocantins were: environmental, maintenance of natural diversity (ADN) and conservation of fish resource (ARP); social, quality of life (SQV) and social organization (SORG); and technical-economical, performance of family economy (TECON), possibility of diversification (TEDIVERS) and efficiency of management (TEFIC). The sustainability of the agroecosystems evaluated was considered satisfactory, in the way that just one agroecosystems showed result(s) lower than the critical level (5,0). Differences were observed between the performances of the agroecosystems with a higher level of external intervention to the ones with lower level of external intervention. However, those results were not totally assigned to this kind of intervention, but also to others variables. These interventions can incline either the valorization and maintenance of natural diversity, or the productive specialization. Among the considered dimensions, the best results were attributed to the environmental and technical-economical dimensions rather than the major variability between the agroecosystems. The social dimension received the lower results, showing major uniformity between the agroecosystems. The MESMIS framework, despite showing some inconsistencies, has proved capable to be used in the region.

Produção da cana-de-açúcar nos municípios de Abaetetuba e Ulianópolis: aspectos climáticos, socioeconômicos e ambientais
(Universidade Federal do Pará, 2016-02-05) VADO ESPINOZA, Julio Cesar; PIMENTEL, Márcia Aparecida da Silva; http://lattes.cnpq.br/3994635795557609; ROCHA, Edson José Paulino da; http://lattes.cnpq.br/2313369423727020
In the last decade, the global increase in demand for sugar for food production and renewable energy sources has impacted the production chain and pressing areas with agricultural potential for sugarcane plantation. The Brazilian government through the Ministry of Agriculture Livestock and Supply developed the Agro-Ecological Zoning of Sugar Cane - ZAE (EMBRAPA, 2009) for the production of ethanol and sugar, excluding among other areas the state of Para for been located in the Amazon Biome. Coupled to this context there is the controversy of whether monoculture which requires deforestation practices, which also derive impacts on the atmosphere, water and soil. Before the contrast to produce and protect the environment is relevant deepening of scientific studies for technical support and justification of alternatives for deployment or expansion of cultivation associated with the mapping of areas already consolidated. This study aimed to analyze the production of sugar cane in the city of Abaetetuba and Ulianópolis, taking into account climatic aspects; socioeconomic and environmental. For climate aspects were used (for both municipalities) climatological data provided by INMET a period of thirty years (1984-2013). The results showed that both municipalities have climatic suitability for the cultivation of sugar cane, with the proviso that for the city of Ulianópolis this crop is dependent on irrigation, which increases production costs and causes increased pressure on groundwater. As refer to socioeconomic and environmental aspects were used different methods for the studied municipalities. For the city of Abaetetuba, the socioeconomic aspects were evaluated in light of the situation on the time of cultivation of height in this city (1970). The results showed that activity represented an important vector to generate employment and income for the local population. Environmentally, the assessed indicators showed low vulnerability to contaminants derived from sugarcane cultivation, which can be explained by the intrinsic characteristics of the aquifer and soil properties in the area. As for the land use, the results showed the existence of degraded areas for the year 2012 related to livestock activity mostly. To the municipality of Ulianópolis was applied to Barometer tool of sustainability, defining sustainable development as that which meets the needs of the present without compromising the ability of future generations to meet their own needs (WCED, 1987). It was found that this city is located in an intermediate range of sustainability, and the increased vulnerability indicators deforestation, exploitation of groundwater and hotspots per km2. Although this study has proposed a number of environmental and socio-economic indicators of relevance, further research should be carried out, given the importance of sugar cane for the development of alternative energy in the region. It is also worth mentioning that from the perspective of the institutional environment (credit, regulatory, environmental, etc.) guided by ZAE, new sugarcane enterprises could be encouraged in degraded areas in the Amazon Biome.

Sustentabilidade e gestão ambiental no município de Moju/PA: desafios para a produção do biodiesel
(Universidade Federal do Pará, 2014-02-26) CARDOSO, Andreza Soares; VIEIRA, Ima Célia Guimarães; http://lattes.cnpq.br/3761418169454490; TOLEDO, Peter Mann de; http://lattes.cnpq.br/3990234183124986
The concept of sustainable development and its further management emerge as a need to think of new ways to measure economic growth. The concept of "Sustainability Indicators”, designed to measure the level of sustainability of a system, based on indices from economic, social and environmental sector, can help in the evaluation to point out to the accomplishment of sustainable development of a specific municipality, region or county. The public policy of biofuels executed under the National Policy on Production of Biodiesel – PNPB, was created to be applied in the Amazon Region, including the State of Pará, through the program "Poles of Biodiesel Production ". In this context, one of the main targets was the municipality of Moju figured as one of the largest producers of palm oil in the northern region of Brazil. Despite the huge expansion of oil palm cultivation in this county, there are strong concerns about the ability of Moju to receive this governmental incentive and development program as an effective public policy for sustainability. The potential for strongs impacts in the territoriality configuration and social menace are high. In addition, due to the expected economic and environmental dynamics in a municipality there has not been a preparation phase through environmental management programs to minimize potential hazards in the different sectors that may be targeted by such program. This Study focused in the understanding and measure of the sustainability level of the municipality of Moju and evaluated its environmental management capacity. Interviews were performed and secondary data were incorporated into a sustainability analysis framework of the Barometer of Sustainability. It was observed that the municipality tends to a low sustainability trend with few socioeconomic and environmental advances, which demonstrates the fragility of this political district in environmental issues. In general, the city has license to exercise full environmental management, i.e., presents a desirable or efficient administrative structure but its operational structure is poor or ineffective, which will certainly show problems to couple with the PNPB economic dynamics.

The settlements in the Amazon are critical to the distribution of land, but its implementation still has many environmental and social problems, which has led to criticism of the sustainability conditions thereof. In recent years, have been sought to develop methods for monitoring rural settlements through indicators of sustainability, but the challenges are still enormous. Regardless of the method used, studies show that the main steps in the analysis of the sustainability of settlements are the identification of themes, setting indicators, defining the limits of the indicators and evaluation of indicators in building sustainability index. Thus, this study aims to examine the level of sustainability of settlements of Pará, through the Barometer of Sustainability (BS), comparing two types of settlements: Conventional Settlement Projects (PAC) and Differentiated Settlement Projects (PAD). Twenty-eight 28 indicators were extracted from an environmental diagnosis made by the National Institute of Colonization and Agrarian Reform - INCRA and tested to BS tool for 12 settlements selected. The results show that there is a slight difference between the settlements, especially in relation to the environmental dimension, but the two terms of settlements occupy the same position on the scale of the Barometer of Sustainability to Potentially Unsustainable.
