A Laboratory without walls: biodiversity education in nutrition training using a garden-based learning method

In the field of nutrition, there is a growing demand for human resources to have the capacity to promote sustainable diets. Nutrition science, however, faces challenges that limit its capacity to build a proper workforce to respond to this demand. The lack of knowledge about biodiversity, central to sustainable diets, is one of them. This deficiency is partly caused by fragmented traditions of thought – social, environmental, and biological - in the area. We argue that biodiversity education with the support of the Garden-Based Learning (GBL) method can help in approaching this limitation. The study is an experience report of professors and students involved in a garden laboratory in the nutrition program at a public university in northeastern Brazil. We describe the laboratory's history, design, and our working methodology focused on the theme of Unconventional Food Plants. We present examples of the application of the method from experiences with plants studied in 2019. The use of the GBL method provided opportunities for actions to address the challenges presented by biodiversity education: discussion of professors' capacities, the institutionalization of the laboratory, the inclusion of a course on Sustainable food systems in the curriculum, work with a multi-professional team, strengthening community ties and adapting tools for cross-cultural contexts. In these actions, we systematically approach knowledge about taxonomy, phylogeny, ecosystems, and cultural diversity. The scarcity of literature on the subject limited our capacity to analyze our work within a frame of reference. We hope our report can encourage similar initiatives by guiding the use of the method. In future research, we intend to measure the impact of these strategies on the development of competencies for working with biodiversity in nutrition training

Challenges to balance food demand and supply: analysis of PNAE execution in one semiarid region of Brazil

This study intended to address the challenges faced by the National School Feeding Program (PNAE) to implement public purchases from family farming, as they understand their role in the transformation of local food systems. For this, we developed a qualitative, exploratory, and descriptive study, in the state of Rio Grande do Norte, located in the northeastern semiarid region, during the regional assessments done by the Collaborating Center for the School Feeding Program in 2018 and 2019. We analyzed the policy from the perspective of the social actors inserted at the ends of the supply and demand chain through the application of questionnaires and focus groups. There were 188 social actors from 45 municipalities taking part in our data gathering. We examined the meeting of supply and demand based on the performance of the policy in the state, and identified that: i) the percentage of purchases between 2011 and 2017 was, on average, 19.1%, demonstrating that, despite not meeting the recommended rate, the state has progressed its investments in this segment; ii) some limitations characterized the limited effectiveness of public purchases of family farming for schools: lack of federal actions to enhance the value of family farming, unfavorable conditions for local agricultural production, low performance of technical rural assistance, menus do not reflect the offer of family farming, difficulties in preparing and executing the public call and insufficient communication between social actors; iii) Action and decision-making, through street-level bureaucracy, depends on the discretion of the social actors. We believe that this study can collaborate in the understanding of structural problems that affect the implementation of the program and assist in the search for alternatives that are consistent with the current needs, aiming at the construction of sustainable food systems.This study intended to address the challenges faced by the National School Feeding Program (PNAE) to implement public purchases from family farming, as they understand their role in the transformation of local food systems.

Integrating Family Farming into School Feeding: A Systematic Review of Challenges and Potential Solutions

Family farming is strengthening its strategic role in school nutrition, but coordinating between school feeding programs and the agricultural sector has proven to be challenging. The goal of this review was to identify the problems that school feeding programs face in acquiring food from family farms. We selected studies from Web of Science, Medline/PubMed, and Scopus and evaluated their methodological quality. Out of 338 studies identified, 37 were considered relevant. We used PRISMA to guide the review process, and we chose not to limit the year or design of the study because it was important to include the largest amount of existing evidence on the topic. We summarized the main conclusions in six categories: local food production, marketing, and logistics channels, legislation, financial costs, communication and coordination, and quality of school menus. In general, the most critical problems emerge from the most fragile point, which is family farming, particularly in the production and support of food, and are influenced by the network of actors, markets, and governments involved. The main problems stem from the lack of investment in family farming and inefficient logistics, which can negatively impact the quality of school meals. Viable solutions include strategies that promote investment in agricultural policies and the organization of family farmers

Biodiversity is overlooked in the diets of different social groups in Brazil

Abstract Food biodiversity is essential for improving nutrition and reducing hunger in populations worldwide. However, in middle and low-income countries, the biodiversity of food production does not necessarily represent food consumption patterns by population. We used Brazil, one of the world's megabiodiverse countries, as a case study to investigate the following questions: what is the prevalence of consumption of biodiverse foods in Brazil, and what are the socioeconomic factors that influence their consumption throughout the country? We used data from a Brazilian representative national dietary survey to estimate the frequency of food consumption of unconventional food plants, edible mushrooms, and wild meat, in according to socioeconomic variables. Thus, we investigated the socioeconomic predictors of Unconventional Food Plants consumption using methods of Machine Learning (ML) and multiple zero-inflated Poisson (ZIP) regression. We showed that biodiverse food consumption in Brazil is low, just related by 1.3% of the population, varying in according to area, ethnicity, age, food insecurity, sex, and educational level. Our findings of low utilization of biodiversity suggest an important mismatch between the rich biodiversity of the country and its representation in the human diet
