Environmental services and floristic characterization of agroforest systems in Expedito Ribeiro community, Santa Bárbara-PA, Brazil

Abstract

The Environmental services are defined as benefits obtained by human beings provided of ecosystem functions of the own environment and can be classified in terms of finality, the agroforestry systems instead, are types of cultivations where the forest, agriculture and animal species are cultivated in ASSOCIATION in the same area and space of time, and can be considered as an important tool in generation of multiple ecosystems services by increasing the biodiversity through association between species. Based on this assumption, the aim of the study was analyze environmental services arise of Agroforestry Systems (SAFs) from the “Expedito Ribeiro” community, as datas, relativetothearborealincrement, carbon quantification by biomass and phytosociology of the species during three years. The research was performed in the community located in Santa Bárbara city - Pa for the years of 2016 to 2018, and results obtained by direct observation, photographic registration, handwritingandSAFs’inventory, where the species were classified as its services, data calculations related to phytosociological parameters, aerial biomass and carbon estimation of each species. Species were identified related with all ecosystems services, and high levels of diversity between the cultivars, and also high values in relation to the carbon sequestration of the arboreal species. This results collaborates about the statement which agroforestry systems are sustainable alternatives that gives social, economics and environment benefits to the communities who uses it as a cultivation tool in comparison to activities more aggressive like agriculture and extensive livestock.
