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.
