    Abstract In several parts of the world, forests have been safeguarded by Indigenous and traditional people, whose plant food production is mostly for self-consumption and for sale based on the promotion of forest biological processes and crop diversification. In the Brazilian Atlantic Forest, Quilombola groups are black communities that have protected and managed agrobiodiversity since the fifteenth century. Although the dynamics of use, production, and donations of Quilombola food plants are still poorly understood, these processes can help us to understand the vulnerability to food insecurity. We analyzed the food security related to food availability in a Quilombola community in southern Brazil (São Roque Pedra Branca), focusing on their dependence on locally produced food plants. Today, São Roque families depend on agriculture, government benefits, and urban low-paid civil construction and general helper jobs. We evaluated the interactions between Quilombola farmers and the cultivated species and varieties and the role of farmer families within the community. The hypothesis is that farmers who produce, manage, and conserve more local species and varieties of plants also contribute to less food vulnerability within the community. The small-scale agriculture carried out by the Quilombolas implies the management of high inter- and intraspecific diversity. During the 2019 agricultural year, 42 species were cultivated in plots and gardens, comprising 83 varieties. Most farmers cultivate a subset of major species and varieties for self-consumption and donations. The farmers who grow the most varieties are the ones who donate the most. Some vulnerability to food insecurity was observed in 53% of the family units. Exchanges and donations between families contribute to the community's food security, but there are still families in a situation of food insecurity. Local agrobiodiversity and established exchange networks strengthen Quilombola food sovereignty.

    Abstract Background: Experts in the Atlantic Forest, the Guarani people have the habit of transporting and exchanging plants due to their mobility throughout the territory. Historically, this habit contributed to the species composition and diversification among different phytophysiognomies that comprise the Atlantic Forest. Medicine and spirituality are traits that stand out within the Guarani culture, which is based on a holistic understanding of physical and spiritual well-being for the person's health. To achieve this balance, they use a range of native and adapted plant species. Our goal is to understand some of the Guarani contributions to the cultural landscape in the Atlantic Forest.
    Methods: We conducted semi-structured interviews with key persons asking about the importance of forest environments for Guarani health and about visits to other Guarani villages and plants exchanged. Data analysis was qualitative, and through a bipartite network of exchanged plants to show current plant exchanges between villages.
    Results: We visited seven Guarani Indigenous Territories in south Brazil, and with the participation of 12 respondents, we registered 27 species that were exchanged through different phytophysiognomies in the Atlantic Forest. These results show an intense movement of plants currently occurring between villages and the importance of these movements for both individual health and the integrity of the environments in which the Guarani villages are inserted.
    Conclusions: We observed a search for the maintenance of traditional species in the Guarani medical system, and we highlight the fundamental role of Guarani management in the conservation of the southern Atlantic Forest in indigenous territories.

    Abstract Soybean meal is the main source of protein used in animal feed worldwide. This highly competitive market leads to the continuous search for improvements in product quality and reduction of process costs. Drying is one of the key steps in the production of soybean meal, contributing significantly to the final quality of the product. In this context, the main objective of this work was to study experimentally and computationally the soybean meal drying in a fluidized bed dryer. In order to determine the kinetics of soybean meal drying and the influence of temperature, speed of drying agent, and bed height on the fluidized bed drying process, experimental runs were performed, varying each of these parameters. The experimental results show that the drying rate of soybean meal has only the decreasing period, so the factor that controls this process is the diffusion inside the material. Temperature had a significant influence on the process, while the height of the bed of particles and the speed of the drying agent did not have significant influence in the range of experimental conditions investigated. An Eulerian–Eulerian model was used to simulate fluid dynamics and fluidized bed drying, and the numerical simulations were performed with the CFD (computational fluid dynamics) code MFIX. A mass transfer model was incorporated into the available fluid dynamics model in order to study the soybean meal drying in the fluidized bed. The comparison of the numerical results obtained through computer simulations with experimental results showed good agreement. The mathematical model is thus suitable to describe both fluid dynamics and drying of soybean meal in the fluidized bed, indicating potential use of CFD in fluidized bed drying problems.
