O Mestrado Acadêmico em Desenvolvimento Sustentável do Trópico Úmido pertence ao Programa de Pós-Graduação em Desenvolvimento Sustentável do Trópico Úmido (PPGDSTU) do Núcleo de Altos Estudos Amazônicos (NAEA) da Universidade Federal do Pará (UFPA). O Mestrado em Planejamento do Desenvolvimento (PLADES) foi implantado em 1977 e foi pioneiro dos programas de pós-graduação stricto sensu das áreas de humanidades e ciências sociais aplicadas na Amazônia.

Item Acesso aberto (Open Access) Dinâmica das relações socioeconômicas e ecológicas no extrativismo do açaí: o caso do médio Rio Pracuuba, São Sebastião da Boa Vista, Marajó (PA)(Universidade Federal do Pará, 2005-07-11) MARINHO, José Antônio Magalhães; ACEVEDO MARIN, Rosa Elizabeth; http://lattes.cnpq.br/0087693866786684The present study analyses the transformations on açaí extrativism along the middle Pracuúba River flood plain (Marajó, PA), stimulated by the fruit demand intensification, envolving both local and extra-local markets. It investigate, on one side, the socio-economic relations established in the fruit extraction and commerce besides showing the coexistence of the market principles on the side of the peculiar relations concerning the old “aviamento” system, and on the other side, the population interactions with the açaí palm, through the several management systems, an being adopted because of the valorization of such resources. So, the açaí palm economics, on the socio-economic plan is being carachterized by “changes” and “continuities”, and on the sphere of the man/environment interactions, a major challenge ahead is to boost the management activities.Item Acesso aberto (Open Access) Dinâmica do processo de inovação do açaí: a trajetória de pesquisa e desenvolvimento do BRS-Pará(Universidade Federal do Pará, 2016-04-28) GUIMARÃES, Camilla Maria Cavalcante; COSTA, Francisco de Assis; http://lattes.cnpq.br/1820238947667908In Pará state açaí is the main product of the fruit-growing, generating an approximate value of R $ 677.2 million. With the expansion of production for upland areas, came the difficulty of standardization and homogeneity of production and thus lower quality. In an attempt to solve this problem, the Federal institute Embrapa Amazônia Oriental developed through genetic breeding the BRS-Pará, first crop for solid ground, with high productivity, early production and production in the off-season. Thus, the research aimed to analyze the process of innovation and profitability of BRS-Pará breeding. For the construction of this analysis it was necessary to characterize the BRS-Pará product developed by EMBRAPA, from the conception of the idea to product development, where were used for the analysis. The technological structure, productive and reproductive problems that gave origin to BRS-Pará were analyzed, through interviews with the technicians responsible for the development of farming. The perspective used to understand the process of innovation and technological came from Lundvall, Freeman, Cassiolato who argues that the process occurs from the interaction between different actors, institutions, support mechanisms and research work in collaboration to facilitate this process. At last, were collected accounting and production data of a farm that works with Açaí BRS-Pará crops, evaluating profitability, productivity and balance point of BRS-Pará crops. To understand the phenomenon we used the notion of paradigms and technological trajectories, based on the notion of Dosi and Nelson, however Costa perspective (2009) was highlighted to be a necessary contextualization of the natural environment in the formation and constitution of paradigms and their trajectories. The production unit analyzed is included in the T5 concept, path defined by Costa, as part of the patriarchal system, where there is an intensive land use and landscape homogenization. The study showed high level of profitability, because the crop enables revenue generation in the period between harvests, when prices rise, as well as the benefits of irrigation for the development of production.Item Acesso aberto (Open Access) Uso dos recursos naturais e sazonalidade no estuário amazônico: estratégias e gestão dos produtores de açaí(Universidade Federal do Pará, 2014-03-07) SOLIS, Karol Natalie Lavado; ALMEIDA, Oriana Trindade de; http://lattes.cnpq.br/0325909843645279The dissertation includes a socio-economic and ecological-environmental perspective in order to identify and understand the answers found by the producers of açaí to improve the way of life to social, natural, and environmental disturbances in the Amazon estuary ecosystem. The research was conducted in five communities in the Islands Abaetetuba, Pará - Brazil. The sample was obtained by the technique of snowball, and consisted of 120 riverine families. The various procedures (right observation, semi-structured and open interviews, information sheets daily production activities, and development of eco-seasonal calendar), were used to support the analysis, which focused on analyzing the economic strategies of uses natural resources by producers of açaí as adaptive response to seasonal ecosystem. The data reveal that the exploitation and sale of açaí fruits (78%) are the main economic activities of the estuarine floodplain, followed by fishing livelihoods activities (fish: 64% shrimp and 63%), and the extraction of Buriti (36%), which are considered complementary activities in the coastal economy. Situation that at risk by intensifying the cultivation of açaí and tendency to monoculture of the palm and services changing the diversity of the estuarine ecosystem. But these activities are not, however, developed in isolation, but are part of a complex and integrated system of production and diverse use of natural resources, in view of generating more income for families. By adaptation (resilience) generated from living with the changes or environmental and economic (intensification of cultivation of açaí, increasing temperatures, intensification of rainfall, air and water pollution), the disruption strategy of diversifying economic activities will allow riparians have higher annual gross income and improve the quality of ecosystem services (good local climate regulation, increased production of nutrients to the soil, and have higher carbon stocks).
