Agroforestry systems, legislation and sustainability of small farms in Rio Grande do Sul, Brazil

Abstract

Agroforestry systems (AFS) represent an alternative to the current agricultural model, based on monoculture, mechanization, and intensive use of agrochemicals. The aim of this study was to characterize existing AFS in the Southern region of Brazil and understand how their forestry certification process is conducted by the official governmental body (SEMA-RS). Interviews were carried out with the owners of five AFS and one technical visit was made to SEMA-RS. Changes in production model resulted from a process of raising farmers awareness, which was observed when the main reason mentioned by farmers for implementing AFS is to ensure a healthier life quality. Another reason mentioned is that this system is economically and environmentally feasible and complies with current legislation. On the other hand, SEMA-RS facilitated the certification process by developing a simplified and quicker modality for AFS. The support of technicians and associations helps by providing access to information and to a successful production. This study confirms the effectiveness of AFS and the need to further their visibility so that they are implemented in other locations, especially in degraded areas, thus contributing with environmental preservation and with improving the health of the population, from farmers to consumers.

Sistemas agroflorestais, plantas medicinais e a bioeconomia dos saberes populares

“…A grande vantagem do aproveitamento comercial de folhas, cascas e sementes é que não implica na supressão do indivíduo, possibilitando também a geração de renda em plantios de restauração ecológica ou em áreas de reserva legal (RL) ou áreas de preservação permanente (APP) (Elevicht et al, 2018;Kronhardt et al, 2021;Ronchi et al, 2022). Folhas, sementes, cascas e o látex das plantas constituem produtos florestais não-madeireiros (PFNMs) de valor medicinal e econômico, que são comumente utilizados em todo o mundo (Silva et al, 2018).…”

“…Como alternativa produtiva ao modelo agrícola hegemônico, o qual é fundamentado na monocultura e na intensificação do uso de agroquímicos e da mecanização, o sistema agroflorestal agroecológico, ou biodiverso e sucessional, tem sido apontado como um sistema de produção de viés regenerativo, sendo capaz de produzir benefícios ecológicos, sociais e econômicos (Elevicht et al, 2018;Steenbock et al, 2020;Kronhardt et al, 2021).…”
