O Programa de Pós-Graduação em Desenvolvimento Sustentável do Trópico Úmido (PPGDSTU) pertence ao Núcleo de Altos Estudos Amazônicos (NAEA), da Universidade Federal do Pará. O NAEA existe desde 1972, quando foi concebido como uma unidade de Pós-Graduação e de Pesquisa Interdisciplinar voltada à análise da dinâmica social, econômica e ambiental da Amazônia. No plano institucional, tinha a finalidade, enquanto instituto interdisciplinar, de propiciar a integração da Universidade Federal do Pará (UFPA) em suas diversas áreas de conhecimento, além de iniciar propostas de integração de pesquisas e ensino de pós-graduação no plano internacional, principalmente no que diz respeito à Pan-Amazônia.

    Grãos na floresta: estratégia expansionista do agronegócio na Amazônia
    (Universidade Federal do Pará, 2012) COSTA, Solange Maria Gayoso da; ALMEIDA, Alfredo Wagner Berno de; http://lattes.cnpq.br/1596401343987246; ACEVEDO MARIN, Rosa Elizabeth; http://lattes.cnpq.br/0087693866786684
    This thesis aims to analyze the social structures of the field of soybean production in Amazon, as well as the various strategies used by the main actors in society. The primary findings of this study is that the growth of soybean plantations in the Amazon does not constitute mere agricultural expansion, but the result of a planned expansionist strategy of agribusiness grain established on four structural elements: the specialized migration, the land market, the logistical infrastructure of transport and disposal of production and the influence of environmental factors in the organization of productive activity. For demonstrate this strategy, taking as reference the theoretical-methodological of Bourdieu’s fieldwork theory and empiricism as the field of soybean production in the middle region of the Lower Amazon, with the identification of the social dynamics of each element and their relationships, as well as the positioning of social actors in the economic field. Also this demonstrates that in the field of soybean production, key stakeholders are organized in associative networks equipped with internal hierarchical positions among themselves, that in certain situations and moments hold common interests. Thus, it identifies the existence of two large integrated networks by social agents of agribusiness (the producers and agribusiness) and a third formed by social workers who suffer the effects of the field (family farmers, peoples and traditional communities). In the third network agents have in common the "fragile" condition to impose their way of life and maintain their territory before the aggressive expansionist strategy of agribusiness, led by its agents and the State. The study evidences also that the field of production of soybeans is a territory of struggle between antagonistic forms of appropriation and use of natural resources in the Amazon.

    Passivo ambiental de nutrientes e matéria orgânica na agricultura empresarial de Mato Grosso
    (Universidade Federal do Pará, 2017-04-24) GOMES, Vallência Maíra; CAMPOS, Índio; http://lattes.cnpq.br/9134366210754829
    The intensive exploitation of soils of Mato Grosso-Brazil savanna, associated with inadequate farming techniques has taken to an increasing and noticeable soil degradation. As a result, grows among the large farmers of Mato Grosso the adoption of the no-tillage system. The environmental chemistry and agronomy allied to ecological economics and environmental management provide the interdisciplinary basis of this study, which aims to estimate the environmental liability of nutrients and organic matter of the soil in the mato-grossense savanna from the perspective of the economic viability of different soil management systems. After the identification of areas in which the environmental costs were or were not incorporated, was made the economic-financial feasibility analysis, considering the different types of management. The results point to a segmented reduction of environmental liabilities in areas where no-till farm system is adopted. However, in the short term, higher profitabilities is still combined with less sustainable traditional management techniques. However, other externalities are still associated of the no-tillage not addressed in this study, such as more intensive use of herbicides and insecticides, which may compromise its environmental results.

    As políticas agrícola e de defesa civil em áreas vulneráveis na Amazônia Legal
    (Universidade Federal do Pará, 2017-12-15) SILVA, Lidiane de Souza; RAVENA, Nírvia; http://lattes.cnpq.br/0486445417640290
    The Amazon region carries a long course of government intervention, which affected the adopted development model. Consequently, the interest regarding how the existing institutional fixes for agricultural policies and National Policy on Protection and Civil Defense (PNPDEC) could contribute to face problems connected to extreme events that occurred in this region, increased. This thesis analyses, the institutional arrangements proposed during two different national public policies period, the agricultural and protection policy and the civil defense policy. Those policies were implemented by the state in rural areas of the Legal Amazonia. The research question was “By which means do the agricultural policies possess the intersectoriality needed to envisage the vulnerabilities and risks resulting of the extreme events occurred in rural areas of the Legal Amazonia? This analysis was carried using the Multiple Stream and the discourse analysis associated with the Institutional Analysis and Development Framework, the qualitative comparative analysis and the Fuzzy logic operationalized by the software fsQCA 2.0. The independent variables (X) were socioeconomic conditions, production, institutional and environmental. The conditions found in those variables reflected the intersectoriality existing level between the agriculture policies and civil defense policies. The results confirmed this thesis hypothesis, in which the intersectoriality level among the public policies studied did not allow the acknowledgement of the rural areas located in the countryside of the Legal Amazonia specificities.
