As plantas alimentícias não convencionais (PANC) a partir do conhecimento da agricultura familiar no município de Rio Grande – RS, um estudo de caso

Abstract

Knowledge and appreciation of the local potential of biodiversity and culture can promote the rational exploitation of agrosociobiodiversity resources based on food and nutrition security. In this context, the study aimed to rescue the knowledge of family farmers in the city of Rio Grande - RS about Non Conventional Food Plants (PANC). During the months of March to December 2019, an interview was conducted based on a semi-structured script on the property of 15 family farmers with sampling of the PANC used and located, followed by botanical identification and analysis according to the bibliographic reference on the food potential of the most frequent species. Among the respondents' citations and observations on the properties, the research obtained 315 records of 93 PANC species distributed in 43 botanical families, 12 species corresponding to conventional plants with consumption of unconventional parts. Of the total species, approximately 48% is native (45), 23% is naturalized (21) and 29% is exotic (27) in the state of Rio Grande do Sul, with approximately 57% spontaneous (53) and 43% cultivated ( 40). It is worth mentioning ten PANC cited by more than half of the interviewees, seven of which are fruit and three vegetables. However, many of these species, and of PANC in general, are still not properly offered and consumed, resulting in underutilization of their potential. The dissemination and popularization of PANC is an alternative to enhance agrosociobiodiversity, strengthen family farming and increase the population's diet, contributing to the promotion of food and nutritional security as a route for the development of local food sovereignty.
