Access to food through retail supply chain distribution can vary significantly among the urban poor and leads to household food insecurity. The paper explores this sustainable supply chain phenomenon through a field study among South Africa's urban poor.

Urban metabolic flows is the theoretical basis in the context of supply chain management (SCM). The field study comprised 59 semi-structured interviews in one South African township. Data were recorded, transcribed and translated, and coded using NVivo 12 to provide an inventory of eight themes categorized and patterned from the analysis.

Findings indicate societal factors play a significant role affecting food distribution, access and security from a spatial perspective of retail outlet locations and a nutritional standpoint regarding quality and quantity of food.

The study is exploratory in one township, and while rigorously conducted, the generalizability of findings is limited to this context.

The study practically contributes by providing guidance for food retailers and policymakers to include nutritional guidelines in their distribution planning, as well as the dynamics of diverse neighbourhoods that exist in modern urban contexts.

New forms of retail food distribution can provide better security and access to food for the urban poor, contributing to Sustainable Development Goals (SDGs) 2 Zero Hunger and 11 Liveable Cities.

The study is interdisciplinary and contributes by linking UN SDGs and SCM through urban metabolic flows from development studies as an overarching framework to enable analysis of relationships between physical, social and economic factors in the urban environment.

The purpose of this paper is to examine the impact of urbanicity on rural–urban migrants' dietary diversity and nutrition intake and whether its effect differs across various urban environments of migrants.

Using the individual- and time-invariant fixed effects (two-way FE) model and five-year panel data from the China Health and Nutrition Survey (CHNS), this paper estimates a linear and nonlinear relationship between urbanicity and nutrition. The paper also explores the spatial heterogeneity between rural–urban migrants and rural–suburban migrants. Dietary diversity, total energy intake and the shares of energy obtained from protein and fat, respectively, are used to measure rural–urban migrants' nutrition on both quality and quantity aspects.

The study shows that rural–urban migrants have experienced access to more diverse, convenient and prepared foods, and the food variety consumed is positively associated with community urbanicity. Energy intake is positively and significantly affected by community urbanicity, and it also varies with per capita household income. The obvious inverse U-shaped relationship reveals that improving community urbanicity promotes an increase in the shares of energy obtained from protein and fat at a decreasing rate, until reaching the urbanicity index threshold of 66.69 and 54.26, respectively.

This paper focuses on the nutritional status of rural–urban migrants, an important pillar for China's development, which is often neglected in the research. It examines the urbanicity and the nutrition of migrants in China, which provides a new perspective to understand the dietary and nutritional intake among migrants in the economic and social development. Moreover, the urbanicity index performs better at measuring urban feathers rather than the traditional rural/urban dichotomous classification.

Household food insecurity and poor well-being have increased during the coronavirus disease 2019 (COVID-19) pandemic and resulting lockdown measures. Home food growing has been associated with improved food access and well-being, but it is unknown what role it plays during food supply crises and lockdown. It is also unclear how home food growing and social restrictions may affect opinions about growing food in urban areas (i.e. urban agriculture; UA).

A cross-sectional online survey was conducted during the UK national lockdown in March-April 2020 to measure home food growing, perceived food insecurity, well-being, and opinions of UA. The participants were 477 UK-based adults (369 female, mean age 39.57 years ± 13.36); 152 participants were engaged in home food growing prior to the pandemic. Responses were compared to data collected from a separate sample of participants before the pandemic (N=583) to explore potential shifts in opinions about UA.

Participants who engaged in home food growing had lower levels of food insecurity (U_­=19894.50, z=−3.649, p<0.001, r=−0.167) and higher well-being (U=19566.50, z=−3.666, p<0.001, r=−0.168) than those not engaged in home food growing. Perceived food insecurity partially mediated the relationship between home food growing and well-being; home food growing was associated with less food insecurity, which in turn was associated with better well-being. There were no differences in opinions of UA compared to the sample of participants from before the pandemic.

Home food growing may have had a protective effect over perceived food security and well-being in the early stages the pandemic. Opinions of UA were positive and unchanged compared to data collected pre-pandemic. Policies that support home food growing and access to suitable growing spaces and resources may be beneficial for food system resilience and well-being.

This paper aims to analyze the conceptions that underlie the notion of “sustainable food” of different social actors based on a study focused on promoting sustainable food strategies on university campuses.

The research incorporates the views of various actors linked to a sustainable food project on the campuses of the National Autonomous University of Mexico (Universidad Nacional Autónoma de México), which is one of the most important universities in Latin America. The study includes a literature review on food sustainability strategies on university campuses and implemented sustainable food programmes in 100 universities worldwide. It also incorporates semistructured interviews and discussion groups conducted with consumers of the university community, 60 smallholder farmers and managers of 23 alternative food networks in Mexico City.

This research evidence the diversity of meanings and perspectives associated with food sustainability and a generalized emphasis on its environmental dimensions, although environmental problems tend to be partially understood. It also highlights the priority students and producers give to the accessibility of healthy foods.

The results of this study revealed important elements, potentially useful for designing sustainable food strategies on the campuses, considering the principles of the rights-based approach to development and social participation.

The research evinces tensions in the definition of food sustainability and its translation into actions from a multistakeholder perspective.

The study aims to investigate urban agriculture in the city of São Paulo from the perspective of social capital. The specific objectives are (1) to identify the effects of social capital on urban agriculture and (2) to investigate social capital formation (its sources and challenges imposed onto its development).

Initially, a review of the literature was carried out in order to understand the main concepts used in the field of study. Semi-structured interviews were also carried out with people from urban agriculture initiatives, and they were analyzed under the lens of social capital.

Aspects of social capital were recognized and organized in a framework including sources, effects and challenges. The first deals with consummatory or instrumental sources that generate social capital. The second deals with the following effects: generation of human capital, citizenship, engagement, access and mobilization of resources, and access to information. The third deals with the challenges to its formation related to homophily and the perception of benefits from this form of capital.

Urban agriculture plays an increasingly important role in relieving the pressure generated by the food production system, being part of the solution to food security and sustainability issues. Many researchers recognize important social aspects acting on the dynamics of the movement and the effects of activities on the generation of social capital. The contribution of this work is to deepen the understanding of this type of capital in the context of urban agriculture.

This article draws upon our perspective as academic-practitioners working in the fields of food insecurity, food systems, and inequality to comment, in the early stages of the pandemic and associated lockdown, on the empirical and ethical implications of COVID-19 for socio-economic inequalities in access to food in the UK. The COVID-19 pandemic has sharpened the profound insecurity of large segments of the UK population, an insecurity itself the product of a decade of “austerity” policies. Increased unemployment, reduced hours, and enforced self-isolation for multiple vulnerable groups is likely to lead to an increase in UK food insecurity, exacerbating diet-related health inequalities. The social and economic crisis associated with the pandemic has exposed the fragility of the system of food charity which, at present, is a key response to growing poverty. A vulnerable food system, with just-in-time supply chains, has been challenged by stockpiling. Resultant food supply issues at food banks, alongside rapidly increasing demand and reduced volunteer numbers, has undermined many food charities, especially independent food banks. In the light of this analysis, we make a series of recommendations. We call for an immediate end to the five week wait for Universal Credit and cash grants for low income households. We ask central and local government to recognise that many food aid providers are already at capacity and unable to adopt additional responsibilities. The government's – significant – response to the economic crisis associated with COVID-19 has underscored a key principle: it is the government's responsibility to protect population health, to guarantee household incomes, and to safeguard the economy. Millions of households were in poverty before the pandemic, and millions more will be so unless the government continues to protect household incomes through policy change.

Over the last five years, N8 AgriFood has united the expertise of food systems thinkers across the eight most research intensive universities in the North of England, in a programme working to address key issues around food systems resilience across the themes of food production, supply chains and consumer health. As the programme moves towards focusing the results of its research and combined multidisciplinary expertise into policy guidance, the authors of this paper from within N8 AgriFood take an overview of the work undertaken across the programme's eight member institutions. It explores work around linking communities to food, and the vital potential of the research to inform new policy that encapsulates societal sustainability into food systems thinking.

University students are a unique population with great potential to adopt eating habits that promote positive human and planetary health outcomes. The purpose of this study is to illustrate the current perceptions of sustainable eating behaviours among the students and to examine the determinants of sustainable eating behaviours.

Data were collected from December 2020 to May 2021 through focus group discussions among university students in Ontario, facilitated through synchronous online sessions. There were 21 student participants during the course of five focus group sessions (4–5 participants per session) from various departments within the university. The discussions were transcribed and analyzed for main themes and concepts using open coding; deductive coding based on the framework by Deliens et al. as well as the literature; and inductive coding for emerging themes.

The students had different perceptions about what constituted sustainable eating behaviours, some of which were not based on fact. A variety of individual, environmental (macro, micro and social) and university characteristics were mentioned as factors influencing sustainable food choices, with “food literacy” and “campus food” being the top two factors.

This study presents a novel and holistic overview of how sustainable eating behaviours and sustainable foods are perceived among university students and identifies the perceived determinants of adopting sustainable eating behaviours. This study helps with identifying opportunities to promote sustainable eating behaviours among university students and the design/implementation of informed interventions and policies aimed at improving eating behaviours.

This study aims to offer a research overview of circular food waste management, covering key themes and trends. It analyses state-of-the-art research in this field and proposes an agenda to guide future research.

This study outlines bibliometric analysis from a sample of 349 articles with VOSviewer and SciMat software to identify research trend topics.

The findings reveal a substantial amount of interest in this field. The main research topics relate to the recovery processes and valorisation of food waste and its conversion into renewable and cleaner materials or energy sources, towards circularity. However, these processes require consideration of social aspects that facilitate their implementation, which are currently under-researched.

Companies can target their circular food waste management by considering three key aspects. Firstly, the establishment of closer and more sustainable relationships with various stakeholders; Secondly, a regulatory framework and the support of institutions are both required for the correct implementation of circularity. Finally, what is not measured does not exist. It is therefore necessary to establish indicators to measure both the level of development of circularity in waste management and the fulfilment of the established objective.

This bibliometric analysis looks at the application of circularity principles in food waste management from a holistic perspective, considering different areas of knowledge.

This paper aims to explore a single-institution case study of partnership working between students, the University and Students’ Union, through four student-led sustainability projects. The paper analyses the role and value of these partnerships and provides advice for other institutions on effective partnership working between these stakeholders.

A single case study of partnership working with multiple embedded units of analysis (four projects) is presented based on reflections of practitioners involved in the projects who have different roles within the University and Students’ Union.

The longevity and effectiveness of student-led projects, and disciplinary-breadth of students engaged, can be enhanced by greater collaboration with, and integration into, University and Students’ Union systems. Partnership working between different stakeholders is key to overcoming challenges and the success of student-led projects, helped by key staff “enablers”. These projects provide myriad learning opportunities for developing change agency skills, even where projects are relatively short-lived and could be seen as failures in terms of longevity.

This analysis is based solely on practitioner reflections, with limited direct quantification or qualitative data on the projects’ impacts on the students themselves.

This paper draws together the experiences and reflections of four practitioners with different roles within the University and Students’ Union across four different projects and provides advice to generate student-led sustainability projects which have longevity and impact for wider student populations and future generations of cohorts.
