Item Acesso aberto (Open Access) Contribuição da agricultura urbana e periurbana ao desenvolvimento local do município de Marituba - Pará(Universidade Federal do Pará, 2020-03-06) FRAGELUS, Kente; LIMA, Ricardo Ângelo Pereira de; http://lattes.cnpq.br/1993748824383678; https://orcid.org/0000-0002-3532-422XThe objective of this research is to analyse the contribution of the urban and peri-urban agriculture in the local development of the municipality of Marituba-PA. Thus, the methodology presented a qualitative and quantitative character based on visits to agricultural parcels (direct observation), meetings with farmers and semi-structured interviews. Then, we used GPS map 62s and drone phantom 4 for location of agricultural areas and aerial photography. In summary, the results of our theoretical discussion on the concepts of Territory, Territoriality and Power allows us to conclude that there are all related to geography and respect human spatiality and also present in other areas of knowledge, each with a focus on a certain perspective. Likewise, he started the two circuits of the urban economy: the inferior circuit as the superior circuit do not articulate in the same way because there are different. The two circuits complete each other while remaining different from each other. Certainly, the results obtained demonstrate that urban and peri-urban agriculture contribute significantly to food security and income generation, as well as the local development of the Uriboca neighborhood. In addition, farmers are mostly people with low education and agriculture and their main activity. Therefore, decision-makers should develop public policies that will encourage this activity to generate more profits for the weel-being of Marituba residents.Item Acesso aberto (Open Access) Modelagem ambiental na floresta nacional do Jamanxim-PA: proposta de cenário futuro(Universidade Federal do Pará, 2022-02-21) GAMA, Luana Helena Oliveira Monteiro; ALMEIDA, Arlete Silva de; http://lattes.cnpq.br/1511094180664778Protected areas were created essentially for the conservation of fauna and flora. Analyzing its socio-environmental dynamics becomes a challenge, and at the same time contributes to the understanding of the landscape. The present study aims to model future scenarios from remote sensing and geoprocessing techniques in the National Forest (FLONA) of Jamanxim-PA, based on the land use classification of the years 2013 and 2020. Analyze the independent variables through of Artificial Intelligence. Apply the DINAMICA EGO model using the transition method to simulate deforestation trajectories up to 2030, based on the dependent variables (land cover and use 2013 and 2020) and independent variables (altimetry, slope, distance to roads, distance to settlements and distance to hydrography. The high rates of deforestation within the limits of conservation units, lead to large environmental losses over time. According to INPE, the state of Pará presented the highest forest loss of the Brazilian Amazon states in 2019, a total of 3,862 km2 , with an increase rate of 41% when compared to 2018. Through the mathematical model it is possible to analyze “Where” will be deforested; “When” will it be deforested and what deforestation rates will be; and “How”, what will be the spatial representation of the new areas of modification, that is, how the deforestation process will be based on the dynamic cover and use of the land and the elements that make up the landscape, such as the variations independent activities, it is possible to carry out future projections of deforestation in the FLONA do Jamanxim. Theories of authors representing different currents of Geography are approached to conceptualize space, landscape and dynamic modeling. In Physical Geography, one starts from Bertrand's concepts. For Quantitative Geography, Waldo Tobler was used as a basis. The discussion of Critical Geography is based on the works of Milton Santos. And Soares-Filho for spatial dynamic modeling. The methodology was divided into three main phases: 1- Processing of satellite images, using the supervised classification method through the Maximum Likelihood algorithm; 2- Processing of independent variables; 3- Stage considered the main part of the study, which consists of spatial modeling in DINAMICA EGO. As a result of the analysis of land cover and use, it was observed that there was a reduction in the area of 112.51 km² (0.87%) of primary forest, and an increase in the mosaic class of occupations (deforestation) with an area of 393.53 km², equivalent to 3% of deforested area. The main activities observed were: forest exploitation and mining. There is also a deforestation pattern classified as geometric and regular, with economic activities, such as agriculture, and mainly medium to large-scale grain and livestock monocultures, and an intermediate stage of occupation. The independent variables assume Bertrand's GTP model to observe landscape dynamics. It was observed that 0.28% of the primary forest was converted to deforestation. That is, from 2013 to 2020 deforestation is occurring at a net rate of 28% per year. And there is a high probability of transition from primary forest to a mosaic of occupations, and from forest exploitation to a mosaic of occupations to the north and south of the FLONA do Jamanxim, areas that may be associated with the implementation of roads (BR-163), and to the PDS Brasília and Vale do Jamanxim Project settlements, which consequently can impact the resilience of the landscape. Based on modeling and analysis of future scenarios, it appears that there may be a loss of 198.79 km² (1.52%) of primary forest, and a considerable increase in deforestation of 155.20 km² by 2030. The mapping of this study, it can support public policy actions by analyzing the impact of laws and identifying priority areas for government action in FLONA do Jamanxim. Based on the spatial modeling, together with the command, control and monitoring plans, it is possible to guide the socio-environmental, economic and cultural development in this UC, for the maintenance and conservation of natural assets.Item Acesso aberto (Open Access) A produção do espaço habitado pela comunidade ribeirinha de Boa Esperança no rio Xingu-Altamira-Pará(Universidade Federal do Pará, 2022-08-29) SOUSA FILHO, Hudson Nascimento de; HERRERA, José Antônio; http://lattes.cnpq.br/3490178082968263; https://orcid.org/0000-0001-8249-5024This research addresses issues that arise from the production of the space inhabited by the riverside community of Boa Esperança, located in an archipelago of river islands upstream from the city of Altamira-Pará on the Xingu River. Being located in low latitudes, this community has a short dry season tropical climate regime (am type climate), with stilt houses that occupy the plains that are influenced by the flood regime of the river, the "beiradão", which also offer fertile fields for polyculture agricultural activities. Thus, in general, this research work seeks to understand the production process of the space inhabited by the riverside community of Boa Esperança, at first, enumerating the aspects of the landscape in the daily life of the community, as well as, in addition to these objectives adds the construction of a certain reflexive analysis on the work relations that attribute functionality to the territorial configuration of the community. It was sought to build a certain analysis focused on spatial dynamics with the empirical observation of the socio-environmental conditions existing in the daily life studied and, for this, the research team relied on the application of form interviews and the lifting of aerial images obtained with a drone that helped in the observation of the landscape. Thus, the fact that field research activities have been built with the intention of structuring data and collecting information of spatial historical, socioeconomic and environmental relevance on the context in which the living conditions of the riverside community are developed is mentioned. of Good Hope. This, in turn, shows traces of their ancestry linked to the rubber tappers who migrated from the Northeast to work in the rubber plantations of the middle Xingu, extracting latex mainly from the native rubber trees of the region in the mid-nineteenth century, the decade 1870. Since then, labor activities such as extractivism, burning and artisanal fishing have been the basis of livelihood and trade for riverside families that were constituted with the territorialization of the aviamento system in the region, at the time of the first cycle of the rubber economy.
