Análise sistêmica da biodiversidade de sistemas agroflorestais (SAF) de agricultores familiares em Tomé Açu, PA

Abstract

This research followed the principles of two sciences for the elaboration of this dissertation: a forest ecology and a systemic approach. Seeking to integrate the complexity of family farmers with the richness and floristic diversity of SAF. Aiming, in general, to analyze, from a systemic approach, as possibilities of balance between ecological and socioeconomic factors of Agroforestry Systems (SAF) of family families from Tomé Açu, PA. Thus generating two chapters in the form of a scientific article with the following objectives: to examine the socioeconomic factors that influence the floristic diversity of agroforestry systems (SAF) of family families in the municipality of Tomé-Açu, PA; and analyze how family farmers' practices are able to favor the diversity and floristic richness of agroforestry systems in Tomé Açu, PA. The existence of outlier farmers was found in the correlation analysis, which they are, demonstrated the possibility of a system with high floristic diversity and that is profitable for them. The differential for these farmers reached such a resource that it was reached with a high number of spontaneous species (natural regeneration), but with an even greater number of fruit species for the supri-financial power. A different type of SAF was found, different from the others, called SAF with corridors of natural regeneration. It demonstrates a possibility of a balance between ecological and socioeconomic factors. For, even though it is a highly rich and diverse SAF, in floristic terms, it also provides the means of economic resilience for family members. Thus, the SAF with natural regeneration brokers is recommended for other family farmers who live in situations similar to those used here.
