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

Abstract

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.
