Urban ethnobotany: a case study in neighborhoods of different ages in Chapeco, Santa Catarina State

Abstract

The study of urban home gardens is still a current gap in knowledge in Brazilian ethnobotany researches, especially in the south of Brazil. This study was carried out to survey the species composition of plants in urban residential home gardens of two neighborhoods in the municipality of Chapeco (state of Santa Catarina, southern Brazil): an older neighborhood created prior to the 1950s, and a younger neighborhood created in the decade 1970-1980. It was hypothesized that the home gardens in the older neighborhood would be larger and have greater species richness than those in the younger neighborhood. Data from 10 home gardens in each neighborhood were collected through semi-structured interviews. The plants cited by interviewees were classified as used for alimentary, medicinal and/or ornamental purposes. A total of 372 plant species (256 in the older neighborhood and 248 in the younger one) were recorded. The two neighborhoods differed in the size of their home gardens, but had similar species richness. The high species richness of plants cultivated for alimentary, medicinal and ornamental purposes in both Chapeco neighborhoods indicates that these spaces are an important resource for food, subsistence and well-being.
