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 Chapecó (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 Chapecó neighborhoods indicates that these spaces are an important resource for food, subsistence and well-being.

Os quintais urbanos correspondem às áreas verdes domiciliares dentro dos limites urbanos e têm o potencial de fornecer às famílias uma alternativa barata para a melhoria da dieta e complementação da renda familiar, pela venda de itens produzidos nesse espaço. Este estudo analisa a contribuição dos quintais urbanos antigos na alimentação e na economia doméstica. Os dados sobre a composição dos quintais foram obtidos por meio de entrevistas e pela coleta de plantas presentes nos quintais. As dietas foram levantadas pelo método recordatório das últimas 24 horas, aplicado bimensalmente, durante um ano, para incluir variações sazonais. Verificou-se que a dieta da população amostrada é dependente de alguns alimentos, indicando um nicho alimentar estreito (índice de Levins = 25,9; Levins padronizado = 0,23). As variações nas dietas dos informantes estão relacionadas com o consumo de frutas e hortaliças, em parte fornecidas pelo quintal. Temperos e chás consumidos foram obtidos dos quintais, revelando sua importância para alimentação e saúde. Das 98 espécies alimentares encontradas nos quintais, apenas 38% apareceram na dieta dos entrevistados, indicando uma subexploração dos quintais. Em nosso estudo, a principal função relatada para os quintais foi proporcionar variações da dieta, contribuindo para o consumo de itens diversificados.

Urban homegardens are green areas of households within the city limits and they have the potential to provide families with a cheap alternative for diet improvement, and to complement the income of the families who sell cultivated products. This research analyzes the contributions of old urban homegardens on food consumption and household economy. Data related to homegardens composition were collected by interviews and by collecting cultivated plants. Diets were assessed through a retrospective method (last 24 hours food recall) and administered every two months, during a year, to include seasonal variations. The diet of the sampled population was found to be dependent on certain foods, indicating a narrow food niche (Levins index = 25.9; Levins standardized index = 0.23). Variations in interviewees' diet are related to the consumption of fruits and vegetables, which are partly supplied by homegardens. Spices and teas consumed were obtained from homegardens, revealing its importance in food consumption and health. Among the 98 species found in homegardens, only 38% appeared in the interviewees' diet, indicating an under-exploitation of these homegardens. Our study found that the main role of homegardens is to supply variation in the diet, contributing to the consumption of different types of products.

Com base no enfoque etnobotânico, este estudo procurou caracterizar os quintais urbanos antigos de Rio Claro, realizando um levantamento da riqueza de espécies vegetais e seus usos, em 17 domicílios selecionados aleatoriamente. Os dados foram coletados por meio de entrevistas semi-estruturadas, estruturadas e coleta de plantas. Encontrou-se um total de 410 espécies, distribuídas em 97 famílias botânicas, constatando-se uma alta diversidade de espécies lenhosas, tanto arbóreas como arbustivas (H' = 1,66 e J = 0,86). Foram levantadas 257 espécies de uso ornamental, 98 alimentares e 93 medicinais. Em vista do grande número de espécies encontradas para as principais categorias de uso, pode-se concluir que os quintais desempenham importantes funções no âmbito local das famílias entrevistadas, contribuindo para a produção de alimentos e de medicamentos para consumo próprio, e também desempenhando uma importante função estética graças à variedade de suas plantas ornamentais. A riqueza desses quintais pode estar relacionada com a origem rural e cultural dos proprietários, que ainda mantêm uma tradição de cultivo. Verificou-se que os produtos advindos dos quintais contribuíram para a variação da dieta alimentar dos informantes, representando um potencial promissor para a melhoria da alimentação da população.

This study, based on the ethnobotanical approach, looked for to characterize the ancient urban home gardens in Rio Claro, municipality located in the Southeast of Brazil, carrying out a survey of the wealth of vegetal species and their uses, in 17 households selected randomly. The data had been collected by means of semistructured and structured interviews and by the gathering of plants. It was verified a total of 410 species, distributed in 97 botanical families, evidencing a high diversity of ligneous species, such as trees and shrubs (H' = 1,66 and J = 0.86). There were surveyed 257 species for ornamental use, as well as 98 for alimentary and 93 for medicinal uses. Considering the great number of species found for the main categories of use, it can be inferred that the home gardens play important functions for the interviewed families, contributing for the food and medicine production destined for the consumption by the families themselves, and also playing an important esthetic function thanks to the variety of their ornamental plants. The wealth of these home gardens may be related to the rural origin and to the culture of the owners, who still keep a cultivation tradition. It was found that the products obtained from the home gardens contributed for the diet's variety of the informants, representing a promising potential for the improvement of the population alimentation.
