O Mestrado em Agriculturas Amazônicas teve início em 1996 anteriormente Curso de Mestrado em Agriculturas Familiares e Desenvolvimento Sustentável e reconhecido em 2000 pela CAPES e funciona no Programa de Pós-Graduação em Agriculturas Amazônicas (PPGAA) da Universidade Federal do Pará (UFPA). É um curso interinstitucional, sendo sua oferta responsabilidade do Instituto Amazônico de Agriculturas Familiares - INEAF da UFPA e da EMBRAPA/CPATU – Amazônia Oriental.

    Percepção de agricultores familiares na adaptação do sistema de cultivo de corte e trituração
    (Universidade Federal do Pará, 2002-06-11) OLIVEIRA, Carlos Douglas de Sousa; KATO, Maria do Socorro Andrade; http://lattes.cnpq.br/7117950232304118
    The difficult that small farmers have to obtain tecnologies generated from institutions of the science and tecnology is related with the difficult that researchers have to include the small farmers in their researches but that is not the main problem. The principal problem is the absent from the projects which trouble about to articulate with the cognitive system from small farmers. In this research it was searched to interprete the perception from small farmers on the system of the cultivation from the slash-andmulch proposed by SHIFT project in the northeast of Pará State. Several experiments were accomplised to compare slash-and-burn and slash-and-mulch system at beginning of the perception of the small farmers. It was focussed mainly the management of the work and control from invadeness in the cleared land prepared. The datas more relevant from research were obtained across the attendence of the prepare of the cleared land from the six small farmers. In this moment we can know the tradicional knowledge used in the slash-burn-system. So can appraise that slash and mulch does not present components which unpracticable its articulation with the tradicional knowledge.

    Percepção de um grupo de agricultores da localidade de São João do município de Marapanim-PA, sobre o método de corte e trituração como alternativa ao método tradicional de corte e queima da vegetação secundária

    Farming production systems are in continuous changing, and constantly new exploration techniques arise, affecting the natural resources and modifying the planted media. The impact of a new production system technology may interfere in the agricultors’ knowledge acquired and transmitted through generations. The purpose of this work is to evaluate the aspects of a technical change from traditional cultivation system (slash and burn) to the fire-free system experienced by the small farmers of Community São João (Pará’s northeastern) and its impact over a community’s traditional farming method. Semi- structured and structured interviews were used, as well as visits for data collection with 14 agricultors, who nine are called partner farmers and five neighbor farmers. The results obtained were: The fire-free method changes the small farmers practice (flexibilizates time for area preparation within the agricultural calendar, decreases the number of the work an control from invade ness in cleared land prepared, decreases the time for the area preparation, improves the quality of the ground -thus increasing agricultural productivity-, changes the way they used to proceed for plantation and the work an control from invade ness; the high cost of implantation and maintenance of the fire-free method (price for the machine acquisition and/or use of fertilizers) is considered by the agriculturists as the limiting factor for its consolidation; the small farmers choose the areas for the cultivation according to some characteristics of secondary vegetation (native color, age and species) and don’t consider types of area preparation for cultivation. Thus, this study concludes: (1) the culture systems of the São João locality had suffered impacts due to the technological innovation (fire-free of the secondary vegetation); (2) the preparation method doesn’t determine the choice of the areas for the implantation of the cultives; (3) the soil quality, according to the perception of the small farmers, is more related to the aspects and characteristics of the secondary vegetation.
