Avaliação da sustentabilidade de agroecossistemas familiares agroextrativistas de açaizeiros na região das ilhas do município de Cametá, Pará

The choice of research theme due to the importance that the fruit açai, Euterpe oleracea Mart. represents in the socioeconomics of the Cametá population, mainly the riverside residents, as well asthe concernabout possible changes in the production systems in the agroecosystems of açaí floodplains due to the growing demand for the fruit. Thus, this research aimed to assess to the socioeconomic and environmental sustainability of agroecosystems family who manage açaí in the region of the islands of the municipality of Cametá, Pará. That research was conducted in 52 agroecosystems family, distributed in 19 river islands, between the months of August to December 2012, considering 2011, the year of the crop of the fruit açaí. The agroecosystems were characterized into five dimensions of sustainability: general aspects, social, economic, technological and environmental and later identified the determinants of sustainability (profitability; total cost of production and location of agroecosystems), through exploratory factor analysis, and the similarities observed between the agroecosystems grouped using the technique of the dendrogram (Cluster analysis). When comparing the current state of sustainability of agroecosystems family in the Islands region of Cametá and correlate the açai management adopted, was found that, the most sustainable agroecosystems, considered in descending order, present rural incomes higher than non income rural and adopt management techniques from agricultural researches.

Processos de modificação e a sustentabilidade de agroecossistemas familiares em comunidade de várzea do Município de Cametá - PA
(Universidade Federal do Pará, 2012) RESQUE, Antonio Gabriel Lima; SILVA, Luis Mauro Santos; http://lattes.cnpq.br/7285459738695923; https://orcid.org/0000-0003-1311-1271
This research identified and evaluated the processes of change in Family agroecosystems located in the Baixo Tocantins territory’s township of Cameta, PA, from the influence of external interventions (local development initiatives and rural credit), emphasizing the system diversity as a point that promotes the multidimensional sustainability of these agroecosystems. The methodology used was based on the Indicator-based Framework for Evaluation of Natural Resource Management Systems (MESMIS). The research was carried out in várzea areas of Cametá Township, on the first semester of 2012. The geographic and empiric locus was the Caripi community. Using a table containing 11 indicators of sustainability (1 simple and 10 composed) adjusted to the local reality including the environmental, social and technical-economical dimensions, 11 agroecosystems were evaluated. The data gathering tools used were questionnaire(s), semi-structured guide(s), field notebooks and participant observation. The field research involved the participation of the local actors in the data gathering steps. The field results showed, among the list of indicators proposed, some of them that were most important to the reality of Baixo Tocantins were: environmental, maintenance of natural diversity (ADN) and conservation of fish resource (ARP); social, quality of life (SQV) and social organization (SORG); and technical-economical, performance of family economy (TECON), possibility of diversification (TEDIVERS) and efficiency of management (TEFIC). The sustainability of the agroecosystems evaluated was considered satisfactory, in the way that just one agroecosystems showed result(s) lower than the critical level (5,0). Differences were observed between the performances of the agroecosystems with a higher level of external intervention to the ones with lower level of external intervention. However, those results were not totally assigned to this kind of intervention, but also to others variables. These interventions can incline either the valorization and maintenance of natural diversity, or the productive specialization. Among the considered dimensions, the best results were attributed to the environmental and technical-economical dimensions rather than the major variability between the agroecosystems. The social dimension received the lower results, showing major uniformity between the agroecosystems. The MESMIS framework, despite showing some inconsistencies, has proved capable to be used in the region.
