The impact of urban gardens on food production and nutrient supply is widely recognized in the literature but seldom quantified. In this paper, we present the results of a semi-structured interview conducted in the ‘social gardens’ of Prato (Italy), i.e. areas of land assigned by the Municipality to individual pensioners or unemployed people for the cultivation of vegetables intended for domestic consumption. Some demographic and socio-economic aspects, the cultivated crops and the related areas were investigated. Starting from the areas, the total production of vegetables and their minerals and vitamins contents were estimated. The typical gardener was male, retired, with an average age of 74, and a low level of education. Gardening enabled pensioners to utilize their free time, facilitated physical activity, promoted socialization, and stimulated self-esteem. A 50 m2 plot cultivated on 40% of the area produced an estimated amount of 90 kg of vegetables per year, equivalent to approximately 61.5% of a person's fruit and vegetable needs. Tomato, by far the predominant species, occupied more than 80% of the cultivated area. The highest contributions to nutrients intake concerned Vitamin C and Vitamin A, the lowest Ca and Na. A higher yield and a greater and more balanced nutrient supply could be easily obtained through better use of the land (reduction of uncultivated area and greater assortment of vegetables). In our view, raising gardeners' awareness of this aspect and involving them in training programs on agricultural practices, vegetables composition, and nutrition, could be helpful for increasing the nutrient productivity of the plots and, ultimately, for strengthening the productive function of social gardens.

Most farmland in the US Corn Belt is used to grow row crops at large scales (e.g., corn, soybean) that are highly processed before entering the human food stream rather than specialty crops grown in smaller areas and meant for direct human consumption (table food). Bolstering local table food production close to urban populations in this region through peri-urban agriculture (PUA) could enhance sustainability and resilience. Understanding factors influencing PUA producers' preferences and willingness to produce table food would enable supportive planning and policy efforts. This study combined land use visualization and survey data to examine the potential for increased local table food production for the US Corn Belt. We developed a spatial visualization of current agricultural land use and a future scenario with increased table food production designed to meet 50% of dietary requirements for a metropolitan population in 2050. A survey was administered to row crop (1360) and specialty crop (55) producers near Des Moines, Iowa, US to understand current and intended agricultural land use and factors influencing production. Responses from 316 row crop and 25 specialty crop producers were eligible for this analysis. A future scenario with increased table food production would require less than 3% of available agricultural land and some additional producers (approximately 130, primarily for grain production). Survey responses indicated PUA producers planned small increases in table food production in the next three to five years. Producer plans, including land rental for table food production, could provide approximately 25% of residents' fruit, vegetables, and grains, an increase from the baseline of 2%. Row crop producers ranked food safety regulations, and specialty producers ranked labor concerns as strong influences on their decision-making. Both groups indicated that crop insurance and processing facilities were also important. Increasing table food production by clustering mid-scale operations to increase economies of scale and strengthening supply chains and production infrastructure could provide new profitable opportunities for farmers and more resilient food systems for growing urban regions in the US Corn Belt. Continuing to address producer factors and landscape-scale environmental impacts will be critical in considering food system sustainability challenges holistically.

This paper examines three types of locally oriented Short Food Supply Chains in southern New England and their spatial alignment with a variety of demographic factors. We find that pay-as-you-go operations are particularly likely in predominantly White areas, and to some extent in higher income areas, but box share arrangements (i.e., community-supported agricultures) show stronger associations with educational attainment. Building on these empirical findings, we argue that local food availability is a systematically uneven phenomenon. Through the role of proximity we demonstrate how the dynamics of that availability vary with both outlet type and social characteristics.

Characterizing food systems, i.e., describing their organizational features, can help to generate a better understanding of the structural vulnerabilities that constrain transitions towards sustainable food security. However, their characterization across different economic contexts remains challenging. In this paper, by linking key concepts from research on food regimes, food system vulnerabilities and responsible innovation, we aim to characterize food systems in a developing and a developed economy to identify their shared vulnerabilities. We applied a case study design to characterize food production, processing and distribution in the province of Québec (Canada) and in the state of São Paulo (Brazil). In both cases, the processing and distribution stages have higher economic predominance when compared to the agricultural production stage. Furthermore, we observed concentration in a few activities in both food systems, with a shared focus on export-oriented supply chains. Vulnerabilities in both food systems include: (1) increased interdependence because some supply chains are export-oriented or depend on foreign labor and are, therefore, exposed to external risks; (2) concentration in a few activities, which threatens present and future local food diversity and (3) unequal power relations, making small and medium players vulnerable to decisions made by big players. The characterization developed in this study shows that the two food systems are mainly pursuing economic goals, following the institutional logics of the neoliberal food regime, which are not necessarily aligned with food security goals. It also exposes the presence of characteristics of ‘responsibility’ that may eventually help overcome food systems' vulnerabilities and support transitions toward sustainability.

There have been growing concerns about exposure to chemical pesticides in fresh fruits and vegetables, which are an important part of a healthy diet. This study investigates consumer preferences for reduced pesticide, organic, local, and Missouri Grown produce using a discrete choice experiment. An online survey of fresh tomato consumers was conducted in Missouri to collect choice data, demographic information, and the individual health and environmental attitudes of shoppers. Respondents were willing to pay a premium of 6% for tomatoes produced with 50% less pesticide than conventional tomatoes. The finding indicates there may be a demand for reduced pesticide produce as a compromise between conventional and organic products in terms of price and safety. Also, we found complementary effects between the reduced pesticide attribute and local or Missouri Grown labels, which means consumers in this segment would pay more for fruits and vegetables that were also locally produced. The results suggest important implications for local producers and policy makers in terms of the production and marketing of reduced pesticide produce, such as the need to develop a reduced pesticide label.

Although research on the consumers of farmers' markets spans four decades, no prior study has reviewed the most important characteristics of this consumer segment. Our study collects all the survey-based empirical information available in academic journals listed by WoS and Scopus. Based on the outcomes of 103 studies from 21 countries, consumers are described according to their sociographic characteristics and economic, environmental, and social parameters. Results clearly indicate a homogeneous group, with minor variation mainly due to regional specificities, and identify 27 very typical characteristics. The study identifies key implications for managers and policymakers and provides an agenda for further research.
