Abstract

The aim of this study is to evaluate the importance that the diversity of agroforestry systems (SAFs) have for the sustainability of agroecosystems in the community of Santa Luzia, located in the city of Tomé-Açu, Northeast of Pará, in which for more than two decades cultivate pepper kingdom (Piper nigrum L.). In order to search for information on environmental and socio-economic aspects of agroforestry systems and to establish a relationship to the sustainability of agroecosystems farming families of this community, we used an Mark for Evaluation of the Systems for Management of the natural resources incorporating Indicators of Sustainability (MESMIS). We investigated the reality of 28 farming families in the community, 18 families with SAFs in agroecosystems and 10 families without SAFs in agroecosystems, using as data collection tools, questionnaires familiar characterization of agroecosystems either with or without SAFs. According to the results it was evident that agroecosystems with SAFs are more sustainable than without SAFs. The results show that using the SAFs the level of sustainability is high, while the agroecosystems without SAFs are mostly lower than the critical level of sustainability (5,0). Therefore agroecosystems with the SAFs have higher composition of your grade in the social dimension of sustainability, due to the presence of the Association of Producers and Producers Rural Family Farming the City of Tome-Acu (APPRAFAMTA) that besides being a source of support for marketing of agroforestry products also generates income and encourages the maintenance of local resources.
