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.

Manejo de população de açaizeiro (Euterpe oleracea Mart.) em parcelas de produção de frutos em área de várzea

The management of the açaí stem is done with the objective of increase fruit production and is given by the elimination of the little productive stems or surpluses stems, as well as others of their surroundings, for the purpose of reduce ecological competition for water, light and nutrients. The objective of the research was to contribute with the sustainable management of acai from the study of the relation between the different forms of management and the production of fruits. The study was carried out in three management parcels adopted in an area of one producer selected from among the 6 producers visited in the community of Manoel Raimundo, district of Janua Coeli in the municipality of Cametá, the case, therefore, of an establishment in peasant environment. From a qualitative and quantitative approach, as well as methodological procedures such as: observation and analysis of the landscape, interviews, forms and semi-random sampling it was possible to identify and select the management parcels through different management modes in relation to plant density control practices due to the thinning of stems in the acai plant, the elimination or thinning of the accompanying vegetation. Considering the management history of the parcels they were taken as treatment and called: Parcel 1 (Farmer management), Parcel 2 (Management of technical guidance) and Parcel 3 (Extractivism). Inside of each of them were demarcated with pickets three subparcels with dimensions of 6 m x 12 m each that corresponded the repetitions of the experiment. They were incurred samples to characterize the plant population morphologically through the indicators: number of açai palm per area, number of stems per plant of açai palm, number of bunches per stem, number of rachis per bunch, number of fruit per rachis and fruit weight. The data collected at the sites refer to the accompanying plants, the acai plants, pH and soil moisture. The results showed high variability of the indicators studied in the parcels and in the repetitions. Besides that, three forms of thinning of stems were identified, being classified as light, strong and without thinning. The research concludes that there is a thinning intensity in açaí plants in floodplain areas which results in a rhythm of production proportional to the control of thinning of stems and points to management as the main factor of fruit yield.

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.
