Item Acesso aberto (Open Access) Análise da sustentabilidade e do potencial de implantação de uma reserva da biosfera no Marajó, Pará(Universidade Federal do Pará, 2017-02-13) QUINTELA, Patrick Diniz Alves; VIEIRA, Ima Célia Guimarães; http://lattes.cnpq.br/3761418169454490; TOLEDO, Peter Mann de; http://lattes.cnpq.br/3990234183124986The sustainable development agenda has emerged as a new paradigm associated to the relationship between economic growth and the use of natural resources. Inasmuch, its assumptions should guarantee for future generations the balance between the processes of nature and society. The Man and Biosphere Program, launched in 1971, has been considered as one of the most important biological conservation programs of the United Nations Educational, Scientific and Cultural Organization (UNESCO). The strategy of creating Biosphere Reserves (RB) has moved the scope from global policy to local implementation projects. These units have since 2008 taken on the task of consolidating pristine areas in the construction of sustainability, combining natural landscapes with sustainable use through the participation of local populations. In this context, this interdisciplinary research analyzed the environmental and economic conditions of the municipalities of Marajó, Pará, applying the tool Barometer of Sustainability (BS). In addition, such results were used in the analysis of the challenges for the implementation of a Biosphere Reserve in the Marajó. Of the municipalities that make up the Marajó territory, 13 were pointed as potentially unsustainable, and the remaining three fell within the intermediary range of sustainability. According to the Barometer of Sustainability scale, all municipalities demonstrated critical socio-environmental conditions, creating an additional challenge for the implementation of the Biosphere Reserve due to such development background.Item Acesso aberto (Open Access) 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/3990234183124986The 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.Item Acesso aberto (Open Access) Sustentabilidade em assentamentos rurais do estado do pará: uma aplicação do barômetro da sustentabilidade(Universidade Federal do Pará, 2014-02-27) SILVA, Veríssimo César Sousa da; VIEIRA, Ima Célia Guimarães; http://lattes.cnpq.br/3761418169454490The 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.Item Acesso aberto (Open Access) Vulnerabilidade ao fogo de florestas intactas e degradadas na região de Santarém - Pará(Universidade Federal do Pará, 2012-08-31) COSTA, Carla Daniele Furtado da; PARRY, Luke Thomas Wyn; http://lattes.cnpq.br/3567943056179690; VIEIRA, Ima Célia Guimarães; http://lattes.cnpq.br/3761418169454490The Amazon is constituted today as the largest tropical rain forest remnant and continuous world and home to the largest diversity of plants and animals of all the Earth's biomes, and is critical to maintaining biodiversity. The region has undergone significant changes in recent decades, changes that are resulting mainly from changes in the landscape / vegetation cover, driven by population growth and inappropriate management practices of land, the result of deforestation, fires, changes in agricultural activities, livestock, farm logging, colonization programs, opening of roads and problems landowners. Among these factors, burning and forest fires becomes the most critical problem for the region, for fire management by farmers in most cases is done improperly, escaping control and causing economic damage, social and ecological. Forests that have burned since become more susceptible to new fires, as they become more flammable due to the change in canopy structure, dynamics of relative humidity, air temperature and fine fuel on the forest floor. Thus, this study aimed to investigate the diurnal patterns of flammability of intact and degraded forests in the region of Santarém - PA, area of major changes in land use pattern, with intense agriculture and farming, the region also presents significant number outbreaks of fire. It was observed that intact forests in the region are significantly less flammable than the degraded forests, and edges of degraded forests are more flammable than inside, supported by data on the dynamics of relative humidity and air temperature, humidity and rate of litter opening the canopy. These data were associated with socioeconomic data through interviews, in order to learn how farmers manage the fire, where the results showed that the training of fire management significantly influence the adoption of best practices in use of fire, for example, do not put fire in time critical (between 11 and 15 hours for the study area), making steel, burn against the wind, waiting for the first rain, among others. The size of the property does not significantly influence the proper use of fire, but small farmers are the ones who use it in their productive activities, since this constitutes the cheapest way to clean and prepare the land. In this sense, this paper aims to show the need for investment in research on the flammability of forests, improvement of the analysis of satellites associated with field research as a way to soften and perhaps solve the problem of fires in the Amazon, and contribute to adoption of a policy of encouraging the reduction of burning by farmers, coupled with the use of fire training, access to information technologies and alternatives to fire management.
