A recipe for change: Analyzing the climate and ecosystem impacts of the Brazilian diet shift

Diet shift is an opportunity to mitigate the impacts of food systems, which are responsible for about a third of greenhouse gas (GHG) emissions globally and exert various environmental pressures on ecosystems. This study evaluates the mitigation potential of both global and local environmental impacts through dietary changes within the Brazilian context. Furthermore, the study aims to identify the potential benefits and trade-offs that may arise from these dietary transitions, thus providing a comprehensive analysis of the overall environmental implications. To this end, a life cycle assessment (LCA) was performed to evaluate the environmental impacts of a conventional diet in Brazil and seven alternatives, namely adjusted-EAT-Lancet, pescatarian, vegetarian, entomophagic (insect-based food), mycoprotein (microbial-based food), and synthetic (cell-based food) diets. Results indicate a substantial mitigation potential for GHG emissions (4-9 kg CO2e/cap/day) (39 % to 86 %) and land use (4-9 m2/cap/day) (38 % to 82 %) through a diet shift from a conventional diet to any of the seven alternative diets. However, certain trade-offs exist. A diet shift demonstrates no mitigation potential of soil acidification, and opportunities to reduce water eutrophication (0.02-0.2 g Pe/cap/day) (2 % to 24 %) and water consumption (0.2-0.5 m3/cap/day) (7 % to 14 %) were only found by completely substituting animal products for insect-based food, microbial-based food, and cell-based food. This study highlights the considerable potential of dietary changes to mitigate global environmental impacts associated with food systems. By revealing opportunities and challenges, this study supports science-based decision-making and guides efforts toward sustainable and environmentally friendly food consumption patterns.

Applying a climate-biodiversity-health framework to support integrated food systems planning and policy

Food systems impact different aspects of sustainability and human life, such as pollution, health, climate change, biodiversity loss, water shortage, and soil infertility. However, in many places, food systems are neither resilient nor sustainable. Integrated planning approaches can help to overcome fragmented strategies and policies in ways that improve the sustainability and resilience of food systems. This study explores such an approach by applying a climate-biodiversity-health (CBH) nexus to local and regional food systems in the Comox Valley region, British Columbia, Canada. The CBH nexus is used as an analytical lens to identify systems relationships among food systems, climate change, biodiversity and health issues and strategies in the region. The employs a place-based approach entailing semi-structured interviews with provincial, regional, and local stakeholders in order to develop a holistic understanding of planning challenges, strategies and their outcomes through the CBH lens. Outcomes of this work include a system map that can be used as a framework for elucidating how various strategies align or conflict with different CBH imperatives and can be used to support integrated community sustainability planning and policy-making efforts. The framework is developed within the Comox Valley context, but it can be adapted to other communities. This paper details the development of this framework, the interconnections between different components, and how this framework can be adopted in other communities.

Does urban agriculture contribute to food security, and how might this be achieved?

OBJECTIVE

Food system challenges exacerbate inequalities in access to fresh healthy food and threaten food security. Lack of food security, referred to as food insecurity, is associated with poorer physical and mental health outcomes and has been identified as a key challenge to address by calls for food system transformation. Increasing food production through urban agriculture, the production of fruit and vegetables in urban areas, has been identified as a potentially effective contributor to food system transformation, but the effect of this on household or UK-level food security is unclear. This paper reviews international evidence of urban agriculture's impact on food security.

DESIGN

Narrative review.

SETTING

This paper reviews international evidence of urban agriculture's impact on food security.

PARTICIPANTS

Previously published international research.

RESULTS

Whilst findings are mixed, available evidence suggests that urban agriculture makes a modest, yet positive, contribution to food security by facilitating the availability of and access to fresh fruit and vegetables to food insecure households.

CONCLUSIONS

Capitalising on the potential for urban agriculture to benefit food security requires government investment and support at both the national and local levels; therefore, increasing access to land for food growing, reducing costs of related resources and collaboration with existing community groups to enhance sharing of skills and expertise are identified as avenues for exploration that may help to achieve this. This review also highlights opportunities for future research in this field that may strengthen the quality of the evidence supporting urban agriculture's impact on food security.

Farm forests, seasonal hunger, and biomass poverty: Evidence of induced intensification from panel data in the Ethiopian Highlands

Seasonal hunger is the most common food insecurity experience for millions of small dryland farmers. This study tests the relationships between food insecurity, farm forests, and biomass poverty using a longitudinal dataset from the Amhara region of Ethiopia. These data form part of the Ethiopia Socioeconomic Survey, which collected panel data over three survey rounds from 530 households between 2011 and 2016. This dataset represents a collection of unique socioeconomic, wellbeing, and micro-land use measures, including farm forests. Hierarchical mixed effect regression models assessed the relationship between food insecurity and farm forests as well as the conditional effects of biomass poverty among the poorest farmers and women-headed households. Over a six-year study period, farmers reported increased stress from smaller land holdings, higher prices, and climate-related shocks. A clear trend towards spontaneous dispersed afforestation is observed by both researchers and satellite remote sensing. Model results indicate, dedicating approximately 10% of farm area to forest reduces months of food insecurity by half. The greatest reductions in food insecurity from farm forests are reported by ultra-poor and crop residue-burning households, suggesting that biomass poverty may be a major constraint to resilient food security on these farms. This research provides novel quantitative evidence of induced intensification and food security impacts of farm management preserving and building stores of biomass value as green assets. The results reported here have important implications for nature-based solutions as a major strategy to achieve sustainable development in some contexts.

Corporate interest groups and their implications for global food governance: mapping and analysing the global corporate influence network of the transnational ultra-processed food industry

BACKGROUND

A major challenge to transforming food systems to promote human health and sustainable development is the global rise in the manufacture and consumption of ultra-processed foods (UPFs). A key driver of this dietary transition is the globalization of UPF corporations, and their organized corporate political activity (CPA) intended to counter opposition and block government regulation. UPF industry CPA and the corporate interest groups who lobby on their behalf have been well described at the national level, however, at the global level, this network has not been systematically characterized. This study aims to map, analyse, and describe this network, and discuss the implications for global food policy action on UPFs, global food governance (GFG), and food systems transformation.

METHODS

We conducted a network analysis of the declared interest group memberships of the world's leading UPF corporations, extracted from web sources, company reports, and relevant academic and grey literature. Data on the characteristics of these interest groups were further extracted for analysis, including year founded, level, type, and headquarter location.

RESULTS

We identified 268 interest groups affiliated with the UPF industry. The UPF manufacturers Nestlé (n = 171), The Coca-Cola Company (n = 147), Unilever (n = 142), PepsiCo (n = 138), and Danone (n = 113) had the greatest number of memberships, indicating strong centrality in coordinating the network. We found that this network operates at all levels, yet key actors now predominantly coordinate globally through multistakeholder channels in GFG. The most common interest group types were sustainability/corporate social responsibility/multistakeholder initiatives, followed by branding and advertising, and food manufacturing and retail. Most corporate interest groups are headquartered where they can access powerful government and GFG decision-makers, nearly one-third in Washington DC and Brussels, and the rest in capital cities of major national markets for UPFs.

CONCLUSIONS

The UPF industry, and especially its leading corporations, coordinate a global network of interest groups spanning multiple levels, jurisdictions, and governance spaces. This represents a major structural feature of global food and health governance systems, which arguably poses major challenges for actions to attenuate the harms of UPFs, and to realising of healthy and sustainable food systems.

School food hero and the battle of the food foes: A story of public health policy, power imbalance and potential

This paper explores the impact of school food policy from the perspective of school food workers to offer an alternative account of why school food may not be having the desired impact on child health or food choices. Drawing upon the findings from an institutional ethnography carried out in three UK primary schools, we argue that school food is being asked to perform an unrealistic task of luring children and families away from more unhealthy food options, without being given adequate resources or powers to do this job effectively. We theorise that the narrative depicting school food as a hero, combatting the harms of poor dietary choices and poor health outcomes, is inappropriate as a countermeasure to mitigate the effects of wider food industry forces. We revisit the narrative to consider the power imbalances within society that structure dietary choices, presenting our findings and the wider policy review in the form of a story about the evolution of school food set against a shifting food environment. We conclude with recommendations for policy makers who want to see school food have a greater impact in improving child health.

Conference on 'Sustainable nutrition for a healthy life'

Nutrition scientists are currently facing a substantial challenge: to feed the world population sustainably and ethically while supporting the health of all individuals, animals and the environment. The Nutrition Society of Australia's 2022 Annual Scientific meeting theme 'Sustainable nutrition for a healthy life' was a timely conference focusing on the environmental impact of global, national and local food systems, how nutrition science can promote sustainable eating practices while respecting cultural and culinary diversity and how to ensure optimal nutrition throughout life to prevent and manage chronic diseases. Comprehensive, diverse, collaborative and forward-thinking research was presented in a 3 d programme of keynote presentations, oral and poster sessions, breakfast and lunch symposiums, ending with a panel discussion to answer the question of how we can best achieve a nutritious food supply that supports human and planetary health. We concluded that this complex issue necessitates coordinated efforts and multi-faceted responses at local, national and global levels. Collaboration among consumers, scientists, industry and government using a systems approach is vital for finding solutions to this challenge.

Harnessing the power on our plates: sustainable dietary patterns for public and planetary health

Globally, diet quality is poor, with populations failing to achieve national dietary guidelines. Such failure has been consistently linked with malnutrition and poorer health outcomes. In addition to the impact of diet on health outcomes, it is now accepted that what we eat, and the resulting food system, has significant environmental or planetary health impacts. Changes are required to our food systems to reduce these impacts and mitigate the impact of climate change on our food supply. Given the complexity of the interactions between climate change, food and health, and the different actors and drivers that influence these, a systems-thinking approach to capture such complexity is essential. Such an approach will help address the challenges set by the UN 2030 Agenda for sustainable development in the form of the sustainable development goals (SDG). Progress against SDG has been challenging, with an ultimate target of 2030. While the scientific uncertainties regarding diet and public and planetary health need to be addressed, equal attention needs to be paid to the structures and systems, as there is a need for multi-level, coherent and sustained structural interventions and policies across the full food system/supply chain to effect behaviour change. Such systems-level change must always keep nutritional status, including impact on micronutrient status, in mind. However, benefits to both population and environmental health could be expected from achieving dietary behaviour change towards more sustainable diets.

Impacts of colonization on Indigenous food systems in Canada and the United States: a scoping review

BACKGROUND

Indigenous populations in Canada and the United States (US) have maintained reciprocal relationships with nature, grounded in respect for and stewardship of the environment; however, disconnection from traditional food systems has generated a plethora of physical and mental health challenges for communities. Indigenous food sovereignty including control of lands were found to be factors contributing to these concerns. Therefore, our aim was to conduct a scoping review of the peer-reviewed literature to describe Indigenous disconnection from Indigenous food systems (IFS) in Canada and the US.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-SR) and Joanna Briggs Institute guidelines, we searched MEDLINE, SCOPUS, International Bibliography of the Social Sciences, Sociological Abstracts, and Bibliography of Native North Americans. Data was extracted from 41 studies and a narrative review completed based on study themes.

RESULTS

The overarching theme identified in the included studies was the impact of colonization on IFS. Four sub-themes emerged as causes for Indigenous disconnection from traditional food systems, including: climate change; capitalism; legal change; and socio-cultural change. These sub-themes highlight the multiple ways in which colonization has impacted Indigenous food systems in Canada and the US and important areas for transformation.

CONCLUSIONS

Efforts to reconnect Indigenous knowledge and values systems with future food systems are essential for planetary health and sustainable development. Traditional knowledge sharing must foreground authentic Indigenous inclusion within policymaking.

[The potential of nutrition for pain management and planetary health]

The consumption of western diets that are often rich in animal-source foods and low in wholesome, plant-based foods, has grave implications for public health. This is expressed in a growing prevalence of obesity as well as high rates of cardiovascular and metabolic diseases and some cancers. At the same time, current global dietary patterns are major contributors to global environmental challenges, i.e. the climate and the biodiversity crisis, and are thereby a major threat to planetary health. Shifting to more plant-based diets, e.g. in line with the "Planetary Health Diet", provides a major opportunity to improve individual and planetary health. Plant-based dietary patterns with an increase in the consumption of anti-inflammatory and a decrease in pro-inflammatory substances can also lead to improvements in pain symptoms, especially in inflammatory or degenerative joint diseases. In addition, dietary shifts are a prerequisite to achieve global environmental targets and thereby ensure a livable and healthy future for everyone. Medical professionals therefore have a special responsibility to actively promote this transformation.

Sowing Seeds of Sovereignty: A Qualitative Exploration of Chapter Leader Experiences Who Belong to an African, Caribbean, and Black Women's Agriculture Advocacy Collective

African, Caribbean, and Black (ACB) populations are disproportionately impacted by food insecurity since the COVID-19 pandemic, with reports including limited access to healthy, affordable, and available food resulting in the exacerbation of existing health disparities and poorer living conditions and environments. Many interventions addressing food insecurity among ACB populations incorporate downstream models that emphasize consumer-level solutions (e.g., food donation or assistance programs). While useful for developing short-term solutions, these approaches do not meaningfully engage broader structures and root-causes-and, in many ways, reify existing inequities among these populations. Missing from mainstream dialogue is how food insecurity inequities at the individual level are often generated at higher structural levels and the unique assets of a targeted community or population to grow/distribute their own food and restore frayed transnational cultural foodways. This paper documents a case study of an international, Black women-led agriculture education collective headquartered in the South-Central region of the United States. Drawing on in-depth interviews with affiliate chapter leaders in the United States, US Virgin Islands, and Africa (n = 22), the research investigates how chapter leaders describe unique opportunities and barriers to farming and developing food insecurity solutions. Emergent themes from the data analysis were: (1) diasporically linked barriers, (a) infrastructural/political barriers and (b) patriarchal barriers; (2) mobilizing strategies; and (3) cultural and context-specific solutions. Findings from this study contribute important insights for food security development research centering community-based and grassroots organizing models addressing inequities in food production and health.

A scoping review of the impact of Food Policy Groups on local food systems in high-income countries

This scoping review aimed to explore international evidence on the impact of Food Policy Groups (FPGs) on local food systems, in urban and rural regions of high-income countries. Peer-reviewed and grey literature were searched to identify thirty-one documents published between 2002 and 2022 providing evidence on the impact of FPGs. Activities spanned domains including increasing food equity (e.g. strengthening school meals programmes); increasing knowledge and/or demand for healthy food (e.g. food literacy programmes with children and adults); increasing food access (e.g. enhancing local food procurement); environmental sustainability (e.g. promoting low-waste food items on café menus); economic development (e.g. ensuring local businesses are not outperformed by large food distributors); and increasing food system resiliency (e.g. establishment of local produce schemes). Most FPGs reported conducting activities that positively influenced multiple food system domains and reported activities in urban areas, and to a lesser extent in rural areas. Our study highlighted a range of qualitative and quantitative evaluation strategies used to measure FPGs' impact on local food systems. Our recommendations focus on regular and systematic evaluation and research surrounding the impact of FPG activities, to build the evidence base of their impact. Ideally, evaluation would utilise comprehensive and established tools. We recommend exploring the establishment of FPGs across more regions of high-income countries, particularly rural areas, and forming partnerships between FPGs, local government and universities to maximise implementation and evaluation of activities.

Food, health and sustainability

This review makes a case for taking an integrated 'food systems' approach to explore the links between health and sustainability rather than treating them as separate topics. Unlike more linear 'farm-to-fork' conceptions, a systems approach emphasises the links between domains and sectors, helping avoid perverse effects where an intervention at one point in the system can have unanticipated consequences at other points. Adopting this approach, the review argues that food security and sustainability are as much a socio-cultural as a technical challenge requiring the combined forces of researchers from the natural and social sciences together with a range of stakeholders from government, business and civil society. Meeting the twin challenges of health and sustainability will require changes to intensive food production systems, dietary change and reductions in current levels of food waste. The review explores why dietary practices are so resistant to change seeking alternatives to the deficit thinking that pervades much advice on 'healthy eating'. It explores the locus of responsibility for food system change, emphasising the asymmetrical power relations that shape contemporary dietary choices. The review includes an example of food system research, the H3 project (healthy soil, healthy food, healthy people), which seeks to transform UK food systems 'from the ground up', adopting the principles outlined in the body of the review.

Measuring Women's Empowerment in Agriculture: Innovations and evidence

This paper addresses women's empowerment in agriculture, innovations in its measurement, and emerging evidence. We discuss the evolution of the conceptualization and measurement of women's empowerment and gender equality since 2010. Using a gender and food systems framework and a standardized measure of women's empowerment, the Women's Empowerment in Agriculture Index (WEAI), we review the evidence on "what works" to empower women based on impact evaluations of a portfolio of 11 agricultural development projects with empowerment objectives and a scoping review of livestock interventions. We then review the evidence on associations between empowering women and societal benefits--agricultural productivity, incomes, and food security and nutrition. We conclude with recommendations for measurement and policy.

Integrating knowledge and action: learnings from an implementation program for food security and food sovereignty with First Nations communities within Canada

BACKGROUND

Collaborative approaches to knowledge translation (KT) are important for advancing community-engaged research. However, there is a need for examples of participatory approaches that have effectively supported public health research, program development, and implementation with First Nations communities. To strengthen KT with communities, we proposed a set of guiding principles for participatory planning and action for local food system change. Principles emerged from a cross-community analysis of Learning Circles: Local Healthy Food to School (LC:LHF2S) a participatory program (2015-2019) for Indigenous food system action. The objective was to identify guiding principles for participatory planning and action from key learnings and successes on scaling-up of the Learning Circles (LC) model vertically in Haida Nation, British Columbia (BC), and horizontally in three distinct community contexts: Gitxsan Nation, Hazelton /Upper Skeena, BC; Ministikwan Lake. The application of these principles is discussed in the context of our ongoing partnership with Williams Treaties First Nations to support community planning to enhance food security and sovereignty.

METHODS

A cross-community thematic analysis was conducted and guided by an implementation science framework, Foster-Fishman and Watson's (2012) ABLe Change Framework, to identify key learnings and successes from adapting the LC approach. Information gathered from interviews (n = 55) and meeting reports (n = 37) was thematically analyzed to inform the development of guiding principles. Community sense-making of findings informed applicability in a new community context embarking on food systems work.

RESULTS

Emergent guiding principles for participatory food system planning and action are described within four main areas: (1) create safe and ethical spaces for dialog by establishing trust and commitment from the ground up, (2) understand the context for change through community engagement, (3) foster relationships to strengthen and sustain impact, and (4) reflect and embrace program flexibility to integrate learnings.

CONCLUSIONS

Emergent principles offer guidance to supporting Indigenous community-led research and mobilization of knowledge into action. Principles are intended to support researchers and health system administrators with taking a collaborative approach that fosters relationships and integration of community leadership, knowledge, and action for food system change. Application of principles with implementation frameworks can strengthen KT in Indigenous contexts by incorporating community protocols and perspectives in support of Indigenous self-determined priorities.

Are the impacts of food systems on climate change being reported by the media? An Australian media analysis

OBJECTIVE

Food systems are a major contributor to climate change, producing one-third of global greenhouse gas emissions. However, public knowledge of food systems' contributions to climate change is low. One reason for low public awareness may be limited media coverage of the issue. To investigate this, we conducted a media analysis examining coverage of food systems and their contribution to climate change in Australian newspapers.

DESIGN

We analysed climate change articles from twelve Australian newspapers between 2011 and 2021, sourced from Factiva. We explored the volume and frequency of climate change articles that mentioned food systems and their contributions to climate change, as well as the level of focus on food systems.

SETTING

Australia.

PARTICIPANTS

N/A.

RESULTS

Of the 2892 articles included, only 5 % mentioned the contributions of food systems to climate change, with the majority highlighting food production as the main contributor, followed by food consumption. Conversely, 8 % mentioned the impact of climate change on food systems.

CONCLUSIONS

Though newspaper coverage of food systems' effects on climate change is increasing, coverage of the issue remains limited. As newspapers play a key role in increasing public and political awareness of matters, the findings provide valuable insights for advocates wishing to increase engagement on the issue. Increased media coverage may raise public awareness and encourage action by policymakers. Collaboration between public health and environmental stakeholders to increase public knowledge of the relationship between food systems and climate change is recommended.

Understanding household and food system determinants of chicken and egg consumption in India

Poultry is one of the fastest-growing agricultural sectors in India and its demand is said to be rising. There is a perception that higher incomes, growing population, urbanisation, and increased productivity in the industry have influenced Indian poultry consumption. However, consumer surveys have shown that the average poultry consumption in India has remained low. With this in mind, the paper analysed household determinants of chicken and egg consumption within the Indian population, using two rounds of National Sample Survey data (1993-1994 and 2011-2012). By conducting a spatiotemporal analysis of household consumption and expenditure survey and by using truncated Double Hurdle and Unconditional Quantile regressions (UQR) models, this study explored socio-economic and food system determinants of chicken and egg consumption in India. Key results highlight that while consumption has increased marginally over twenty years, supply-side determinants, such as price and poultry production concentration, influenced heterogenous consumption patterns in India. We also find evidence that historically marginalised groups consumed more chicken and eggs in comparison to non-marginalised groups and preliminary evidence suggests how household gender dynamics influence different consumption patterns. Adequate consumption of poultry is important to improve nutrient-deficient diets of vulnerable groups in India. Our findings on demand side determinants of poultry products are crucial to support consumer tailored actions to improve nutritional outcomes along with the Indian poultry sector policy planning.

Evolution of global food trade network and its effects on population nutritional status

Changes in food systems during the last decades fostered the establishment of global food networks based on exchanges between countries with different income levels. Recent studies explored configuration and factors associated with trade networks of specific food items during limited periods; however, there is lack of evidence on evolution of trade networks of foods for human consumption and its potential effects on population nutritional status. We present the evolution of the global trade network of foods for human consumption from 1986 to 2020, according to country income level, and we explore potential effects of country network centrality and globalization processes on the prevalence of overweight and obesity. Results show intensification of international food trade and globalization processes in the period of analysis with implications for population nutritional status worldwide.

Local government policy to facilitate healthy and sustainable diets and the broader policy hierarchy: insights from Milan Urban Food Policy Pact cities

BACKGROUND

Local government authorities are well positioned to change the way food is produced and consumed through the implementation of integrated food policies. By facilitating the uptake of healthy and sustainable diet-related practices, integrated local government food policy can trigger change throughout the food supply chain. This study aimed to provide insights as to how the policy hierarchy surrounding local governments may be influencing local government's capacity to create integrated food policy.

METHODS

Content analysis was conducted on local government food policies (n = 36) from signatory cities of the Milan Urban Food Policy Pact were mapped to seven global regions. A set of 13 predetermined healthy and sustainable diet-related practices, organized into three categories: "where to source food", "what to eat" and "how to eat", was used to assess the level of integration of each local government food policy. Additional policies from the broader policy hierarchy that were mentioned in each local government food policy were sourced and then screened for relevancy, charted according to their level of administration (local, national, global region, international) and analysed to consider which diet-related practice(s) each broader policy was likely to promote.

RESULTS

Analysis revealed three key insights: (i) local government food policies across all included global regions (n = 4) mostly promoted practices in the "where to source food" category, (ii) local government food policies across all global regions referred to policies from higher levels of administration (local, national, global region and international) which tended to also promote practices in the "where to source food" category and (iii) regarding the level of integration, local government food policies in Europe and Central Asia targeted the highest number of diet-related practices.

CONCLUSIONS

The level of integration of food policy at national, global region and international levels may be influencing that of local governments. Further research is required to understand why local government food policies are referring to some relevant policies and not others, and to determine whether a greater focus on the diet-related practices of "what to eat" and "how to eat" in policies from higher levels of government would support local governments to also prioritize these practices in their food policies.

Enhancing resilience through seed system plurality and diversity: challenges and barriers to seed sourcing during (and in spite of) a global pandemic

The effects of the COVID-19 pandemic have rippled across the United States' (US) agri-food system, illuminating considerable issues. US seed systems, which form the foundation of food production, were particularly marked by panic-buying and heightened safety precautions in seed fulfillment facilities which precipitated a commercial seed sector overwhelmed and unprepared to meet consumer demand for seed, especially for non-commercial growers. In response, prominent scholars have emphasized the need to support both formal (commercial) and informal (farmer- and gardener-managed) seed systems to holistically aid growers across various contexts. However, limited attention to non-commercial seed systems in the US, coupled with a lack of consensus surrounding what exactly a resilient seed system looks like, first warrants an exploration into the strengths and vulnerabilities of existing seed systems. This paper seeks to examine how growers navigated challenges in seed sourcing and how this may reflect the resilience of the seed systems to which they belong. Using a mixed-methods approach which includes data from online surveys (n = 158) and semi-structured interviews (n = 31) with farmers and gardeners in Vermont, findings suggest that growers were able to adapt - albeit through different mechanisms depending on their positionality (commercial or non-commercial) within the agri-food system. However, systemic challenges emerged including a lack of access to diverse, locally adapted, and organic seeds. Insights from this study illuminate the importance of creating linkages between formal and informal seed systems in the US to help growers respond to manifold challenges, as well as promote a robust and sustainable stock of planting material.

Improving the agri-food biotechnology conversation: bridging science communication with science and technology studies

At a time when agri-food biotechnologies are receiving a surge of investment, innovation, and public interest in the United States, it is common to hear both supporters and critics call for open and inclusive dialogue on the topic. Social scientists have a potentially important role to play in these discursive engagements, but the legacy of the intractable genetically modified (GM) food debate calls for some reflection regarding the best ways to shape the norms of that conversation. This commentary argues that agri-food scholars interested in promoting a more constructive agri-food biotechnology discussion could do so by blending key insights, as well as guarding against key shortcomings, from the fields of science communication and science and technology studies (STS). Science communication's collaborative and translational approach to the public understanding of science has proven pragmatically valuable to scientists in academia, government, and private industry, but it has too often remained wedded to deficit model approaches and struggled to explore deeper questions of public values and corporate power. STS's critical approach has highlighted the need for multi-stakeholder power-sharing and the integration of diverse knowledge systems into public engagement, but it has done little to grapple with the prevalence of misinformation in movements against GM foods and other agri-food biotechnologies. Ultimately, a better agri-food biotechnology conversation will require a strong foundation in scientific literacy as well as conceptual grounding in the social studies of science. The paper concludes by describing how, with attention to the structure, content, and style of public engagement in the agri-food biotechnology debates, social scientists can play a productive conversational role across a variety of academic, institutional, community-level, and mediated contexts.

Food waste in primary schools: Evidence from peri-urban Viet Nam

Schools are a major source of food waste and an important setting for achieving dietary improvements. Few studies explore the links between food waste and nutrition. This study measured individual plate waste of about 1700 primary school children in peri-urban Viet Nam, adding to evidence on school food waste in low- and middle-income countries. We used survey data to explore whether food waste is associated with personal characteristics such as sex, knowledge and attitudes about nutritious foods. Qualitative interviews and focus groups with teachers, parents, food providers and children helped identify potential causes of food waste. The average student wasted 23% of the food served (approximately 85 g) during lunch, which roughly equates to 15.3 kg of food in a school year. Vegetables were wasted most: children left almost half of their portion unconsumed. Boys wasted less food than girls. Better knowledge and attitudes about fruits and vegetables are associated with less waste of these foods. A large portion was associated with a higher share of wasted food, suggesting the potential trade-off between efforts to cut food waste and efforts to increase consumption of nutritious foods. Students were dissatisfied with the quality of the dishes, especially vegetables were evaluated as undercooked, served too cold and too oily. To reduce food waste, it is critical for schools to prepare food in line with students' preferences. Food waste reduction could be treated as an intermediate step towards ultimate policy goals such as healthier food consumption.

Registered Dietitian Nutritionists' Perceptions of the Relationship between Food and Peace in the United States Food System: A Qualitative Study

BACKGROUND

In the United States, persistent food insecurity alongside social and health disparities limit peace in the food system. A peacebuilding approach offers a potential paradigm shift integrating food in the context of peace to foster right and just relationships with self, others, and the Earth for sustainable, resilient, and equitable food systems.

OBJECTIVE

This qualitative study sought to explore registered dietitian nutritionists' (RDNs) perceptions of the relationship between food and peace and to identify implications of food as grounds for peacebuilding, using a Food Peace Framework in the field of nutrition and dietetics.

DESIGN

Virtual, semistructured individual interviews elicited the perceptions and understandings of a purposive sample of RDNs working within the US food system.

PARTICIPANTS/SETTING

Twenty-two purposively sampled RDNs of differing races, ethnicities, ages, places of employment, years of work experience, and diverse geographic locations across the United States were interviewed from October 2021 to January 2022.

ANALYSIS

Qualitative grounded theory iterative coding was performed in three phases: initial, focused, and theoretical coding. Thematic coding analysis with NVivo (version 12.0) was used to organize and interpret data.

RESULTS

Four themes on the perceptions of peace within the US food system emerged, including (1) barriers to peace; (2) conflict in the US food system; (3) values in systems; and (4) new understandings of peacebuilding in the US food system. Four themes of implications of the Food Peace Framework emerged, including implications for (1) education and research communities; (2) nutrition counseling and health care settings; (3) local organizations and programs; and (4) policy.

CONCLUSIONS

This initial study revealed a gap in RDNs' current understandings of peacebuilding in the context of food and acknowledged the need for future research. The Food Peace Framework could offer a comprehensive and inclusive model with the potential to initiate conversations that could address root causes of economic despair, social injustices, and political oppression in food systems.

Nutrient-sensitive approach for sustainability assessment of Australian macronutrient dietary recommendations

BACKGROUND

Dietary guidelines that form the basis for food and nutrition policies in most countries are focused mainly on the social dimensions of health. Efforts are needed to incorporate environmental and economic sustainability. As the dietary guidelines are formulated based on nutrition principles, understanding the sustainability of dietary guidelines in relation to nutrients could support the better incorporation of environmental and economic sustainability aspects into dietary guidelines.

OBJECTIVES

This study examines and demonstrates the potential of integrating an input-output analysis with nutritional geometry to assess the sustainability of the Australian macronutrient dietary guidelines (AMDR) relating to macronutrients.

METHODS

We used daily dietary intake data of 5345 Australian adults from the most recent Australian Nutrient and Physical Activity Survey 2011-2012 and an input-output database for the Australian economy to quantify the environmental and economic impacts associated with dietary intake. Then, we examined the associations between environmental and economic impacts and dietary macronutrient composition using a multidimensional nutritional geometry representation. Thereafter, we assessed the sustainability of the AMDR regarding its alignment with key environmental and economic outcomes.

RESULTS

We found that diets adhering to the AMDR were associated with moderately high greenhouse gas emissions, water use, cost of dietary energy, and the contribution to wages and salaries of Australians. However, only about 20.42% of respondents adhered to the AMDR. Furthermore, high-plant protein diets adhering to the lower limit of recommended protein intake in the AMDR were associated with low environmental impacts and high incomes.

CONCLUSIONS

We conclude that encouraging consumers to adhere to the lower limit of the recommended intake of proteins and meeting the protein requirement through protein-dense plant sources could improve dietary environmental and economic sustainability in Australia. Our findings provide a means of understanding the sustainability of dietary recommendations concerning macronutrients for any country where input-output databases are available.

Farm resilience during the COVID-19 pandemic: The case of California direct market farmers

CONTEXT

The COVID-19 pandemic caused significant shocks to U.S. food systems at multiple scales. While disturbances to long-distance supply chains received substantial attention in national media, local supply chains experienced mixed impacts. As broad closures of schools, restaurants, and other businesses sourcing from local farmers removed key marketing channels for many direct market farmers, consumer interest in Community Supported Agriculture (CSA), farmers markets, and on-farm and online direct farm sales increased.

OBJECTIVE

In this paper, we examine the resilience and vulnerability of farmers during the March 2020 through December 2020 period of the COVID-19 pandemic. We focus on California farmers and ranchers engaged in direct market sales.

METHODS

Through a widely disseminated survey, we collected responses from 364 farmers and used these data to answer the following questions about direct market farmers in California: 1) What were direct market farmers' experiences of the pandemic from March 2020 through December 2020? 2) Which factors (e.g., relationships, institutions, market channels) did farmers report enhanced their resilience during the pandemic? 3) Which individual and operational factors were significantly associated with resilience during the pandemic? And finally, 4) how do the farmer-reported factors compare to the statistically significant factors associated with resilience? We created three dependent variables-ability to respond to the pandemic, concern about pandemic impacts, and change in profitability-to operationalize several aspects of resilience and examine their association with individual and operational characteristics through a series of ordered logistic regression models.

RESULTS AND CONCLUSIONS

Across both the quantitative models and the farmer reported factors, we found that farmers who increased their use of online sales and marketing during the first year of the pandemic, had larger-scale farms, and had more on-farm crop and livestock diversity were more resilient to the shocks of the pandemic. We also found that greater use of non-direct-to-consumer market channels was associated with less resilience. The characteristics of the farming operations played a relatively larger role in predicting resilience compared to the individual characteristics of the farmers surveyed.

SIGNIFICANCE

This study gives a detailed picture of how California direct market farmers fared during the pandemic and the characteristics associated with greater resilience. As short and long-term disruptions become increasingly common in agriculture, policies and programs can leverage support to direct market farmers, particularly direct-to-consumer farmers, as a strategy to strengthen farmer resilience.

Editorial: food and nutrition: pathways to a sustainable future

The world is waking up to the reality of climate change and the challenge of feeding 10 billion people in a healthy and sustainable way. For population and planetary health, food systems need to change. 'Food and nutrition: pathways to a sustainable future' was the first face-to-face Nutrition Society Summer Conference since 2018, bringing together leading contributors from across the globe to explore six pathways to a better tomorrow. Review papers from the conference symposia cut across disciplinary divides showcasing advances in scientific methods and our cumulative understanding of the impact of the food system on climate change. The depth, breadth and advancement of research presented demonstrate the power of collaborative research that can shape industry, individual and population recommendations and create a powerful shift towards the sustainable dietary patterns and systems that are so urgently required.

Agroecological practices in combination with healthy diets can help meet EU food system policy targets

Agroecology has been proposed as a strategy to improve food system sustainability, but has also been criticised for using land inefficiently. We compared five explorative storylines, developed in a stakeholder process, for future food systems in the EU to 2050. We modelled a range of biophysical (e.g., land use and food production), environmental (e.g., greenhouse gas emissions) and social indicators, and potential for regional food self-sufficiency, and investigated the economic policy needed to reach these futures by 2050. Two contrasting storylines for upscaling agroecological practices emerged. In one, agroecology was implemented to produce high-value products serving high-income consumers through trade but, despite 40% of agricultural area being under organic management, only two out of eight EU environmental policy targets were met. As diets followed current trends in this storyline, there were few improvements in environmental indicators compared with the current situation, despite large-scale implementation of agroecological farming practices. This suggests that large-scale implementation of agroecological practices without concurrent changes on the demand side could aggravate existing environmental pressures. However, our second agroecological storyline showed that if large-scale diffusion of agroecological farming practices were implemented alongside drastic dietary change and waste reductions, major improvements on environmental indicators could be achieved and all relevant EU policy targets met. An alternative storyline comprising sustainable intensification in combination with dietary change and waste reductions was efficient in meeting targets related to climate, biodiversity, ammonia emissions, and use of antibiotics, but did not meet targets for reductions in pesticide and fertiliser use. These results confirm the importance of dietary change for food system climate change mitigation. Economic modelling showed a need for drastic changes in consumer preferences towards more plant-based, agroecological and local foods, and for improvements in technology, for these storylines to be realised, as very high taxes and tariffs would otherwise be needed.

The climate crisis is here: a primer and call to action for public health nutrition researchers and practitioners in high-income countries

Dietary behaviours and the food systems in which they occur have a significant impact on climate change. The 2022 Intergovernmental Panel on Climate Change (IPCC) reports and other major climate reports have identified population-level dietary shifts towards balanced, sustainable healthy diets as an important mitigation (i.e. prevention) solution for climate change. Thus, public health nutrition researchers and practitioners have a crucial role to play in combatting the climate crisis. They have the content expertise, interdisciplinary training and technical skills needed to facilitate wide-scale dietary behaviour changes at multiple levels of influence and ultimately improve both human and planetary health. This commentary article: (i) summarises how dietary behaviours and food systems contribute to climate change, with a particular focus on high-income countries; (ii) reviews food-system-related climate change mitigation solutions most relevant to public health nutrition researchers and practitioners; and (iii) identifies key gaps in the literature and future research directions for the field.

Interdisciplinary insights on the future of food systems research: perspectives from the next generation of research leaders

Our dominant food system is a primary driver of worsening human and planetary health. Held in March 2022, the Public Health Association of Australia's Food Futures Conference was an opportunity for people working across the food system to connect and advocate for a comprehensive, intersectoral, whole-of-society food and nutrition policy in Australia to attenuate these issues. Conference themes included food systems for local and global good; ecological nutrition; social mobilisation for planetary and public good; food sovereignty and food equity. Students and young professionals are integral in transforming food systems, yet they are under-represented in the academic workforce, across publishing, scientific societies and conference plenaries. A satellite event was held to platform initiatives from early career researchers (ECR) in areas integral for improving planetary and public good. The research topics discussed in this commentary reflect sub-themes of the conference under investigation by ECR: food systems governance and regulation; local food policies; commercial determinants of health; sustainable healthy diets; and food equity and sovereignty.

Pathways to sustainable land use and food systems in Canada

Meeting global sustainability targets under the United Nations Sustainable Development Goals and the Paris Agreement requires paying attention to major land-use sectors such as forestry and agriculture. These sectors play a large role in national emissions, biodiversity conservation, and human well-being. There are numerous possible pathways to sustainability in these sectors and potential synergies and trade-offs along those pathways. This paper reports on the use of a model for Canada's land use to 2050 to assess three different pathways (one based on current trends and two with differing levels of ambition for meeting sustainability targets). This was done as part of a large international consortium, Food, Agriculture, Biodiversity, Land and Energy (FABLE), which allows for incorporating international trade in meeting both national and global sustainability targets. The results show not only the importance of increasingly stringent policies in meeting the targets, but also the role that population and consumption (e.g., diets) play in meeting the targets. Both the medium and high ambition sustainability pathways can drastically reduce greenhouse gas emissions while protecting forestland.

Governing COVID-19: analyzing the effects of policy responses on food systems in Tanzania

BACKGROUND

The outbreak of the COVID-19 pandemic increased debates on global public health concerns. From early 2020 to 2022, globally, life was upended in the wake of the pandemic. Industries of all kinds were forced to rapidly changed how they work, including agriculture. Particularly for smallholder farmers in developing countries, the COVID-19 pandemic, coupled with climate change effects, negatively affected their livelihoods. Achieving the UN Sustainable Development Goals by 2030 is unrealistic if immediate efforts are not made to address the existential threats facing smallholder farmers. This study analyzes COVID-19 governance and policy responses, examining its effects on smallholder farmers in the south and east of Tanzania using both qualitative and quantitative techniques.

RESULTS

Findings show that mobility restrictions imposed by other countries and fears of the Tanzanian people leading to voluntary isolation resulted in an amended structure of farmers' markets: Reductions in exports, imports and in the purchasing power of the local people followed. Food security was diminished as food availability on the market level was reduced due to mobility restrictions. The impact of COVID-19 resulted in more than 85% of smallholder farmers experiencing an income reduction, thus also increasing the pre-existing vulnerability of these communities. Findings show that farms producing non-exported crops had less severe income reductions and could cope better. The results indicate that only 20% of smallholder farmers started using digital information technology to gather information since physical movements were restricted. Access to technology remained limited in rural areas. Even during the COVID-19 crises, farmers' concerns about the vulnerability of their food systems include non-COVID-19 causes, such as climate change.

CONCLUSIONS

Although Tanzania did not impose a total lockdown, the country was affected by COVID-19, partly via policies of other countries. Impacts included: (i) a decline in local markets as smallholder farmers had fewer trading partners from neighboring states; (ii) a loss of employment opportunities due to the absence of both local and external trade; (iii) reductions of farm output and income; (iv) a lack of agricultural inputs (fertilizer etc.) that are usually imported; (v) fear to continue farming activities due to news about COVID-19 spreading; and (vi) reduction of work efficiency because of a lack of social gathering due to voluntary isolation.While COVID-19 compelled policymakers to make urgent decisions to ensure stable food supply chains, the fundamental task is to address these immediate disruptions while also investing in the long-term goal of a resilient, sustainable, and productive global food system. This can be achieved by adopting a policy package that includes investments in technological development, access to small long-term loans, and regulatory reforms, with which governments can create conditions supporting productive, sustainable, and resilient food systems that can withstand future shocks.

A collective call to strengthen monitoring and evaluation efforts to support healthy and sustainable food systems: 'The Accountability Pact'

There is widespread agreement among experts that a fundamental reorientation of global, regional, national and local food systems is needed to achieve the UN Sustainable Development Goals Agenda and address the linked challenges of undernutrition, obesity and climate change described as the Global Syndemic. Recognising the urgency of this imperative, a wide range of global stakeholders - governments, civil society, academia, agri-food industry, business leaders and donors - convened at the September 2021 UN Food Systems Summit to coordinate numerous statements, commitments and declarations for action to transform food systems. As the dust settles, how will they be pieced together, how will governments and food corporations be held to account and by whom? New data, analytical methods and global coalitions have created an opportunity and a need for those working in food systems monitoring to scale up and connect their efforts in order to inform and strengthen accountability actions for food systems. To this end, we present - and encourage stakeholders to join or support - an Accountability Pact to catalyse an evidence-informed transformation of current food systems to promote human and ecological health and wellbeing, social equity and economic prosperity.

Partnerships in pandemics: tracing power relations in community engaged scholarship in food systems during COVID-19

The COVID-19 pandemic dramatically disrupted food and educational systems, laying bare institutional inadequacies and structural inequalities. While there has been ample discussion on impacts to the food system and higher education institutions separately, there has been little written through the perspective of people who navigate both. Farmers, researchers, graduate students, chefs, and many stakeholders contribute to community engaged scholarship (CES) in food systems, facing novel obstacles and opportunities with the spread of the pandemic. In this article, I utilize institutional ethnography to center the experiences of the people who participated in or led CES projects during the spring and summer of 2020. The goal of this study is to understand how discourse and texts in the academic institution constrain the reality of CES partnerships and identify areas for change. My findings show that tenure and promotion guidelines and funding opportunities constrain CES partnerships, reducing opportunities for relationship building and discouraging innovative models of participation. Quantified evaluation metrics on grant rubrics and tenure and promotion guidelines privilege individual academic researchers growing large programs, writing lucrative grants for the university, and publishing profusely. However, community-led and decentralized projects were able to adapt to community priorities and sustain research projects during the pandemic. COVID-19 created obstacles to community engagement and allowed for creative approaches to community participation. By restructuring academic evaluation and funding processes to support problem-solving models of CES led by community partners, CES projects can support both academic and community priorities in times of disruption and relative stability.

From Ampesie to French fries: systematising the characteristics, drivers and impacts of diet change in rapidly urbanising Accra

Sub-Saharan Africa (SSA) is urbanising rapidly. One of the most visible outcomes of this urbanisation process is the change in the diets of urban residents. However, diet change in the context of rapid urbanisation is a complex and multi-dimensional phenomenon that encompasses multiple intersecting historical, environmental, socioeconomic, and political aspects. This study aims to unravel and systematise the characteristics, drivers and impacts of diet changes in Accra, through the interviews of multiple stakeholders and Causal Loop Diagrams. Diet change is characterised by the increased consumption of certain foodstuff such as rice, chicken, fish, vegetable oil, sugar, and ultra-processed food (UPF), and the decreased consumption of traditional foodstuff such as roots, tubers, and some cereals such as millet. These changes are driven by multiple factors, including among others, changes in income, sociocultural practices, energy access, and policy and trade regimes, as well as the proliferation of supermarkets and food vendors. Collectively, these diet changes have a series of environmental, socioeconomic, and health/nutrition-related impacts. Our results highlight the need to understand in a comprehensive manner the complex processes shaping diet change in the context of urbanisation, as a means of identifying effective interventions to promote healthy and sustainable urban diets in SSA. The development of such intervention should embrace a multi-stakeholder perspective, considering that the relevant urban actors have radically different perspectives and interests at this interface of urbanisation and diet change.

The complex challenge of governing food systems: The case of South African food policy

International experience reveals that food policy development often occurs in silos and offers few tangible mechanisms to address the interlinked, systemic issues underpinning food and nutrition insecurity. This paper investigated what South African government policies cover in terms of different aspects of the food system, who is responsible for them, and how coordinated they are. Policy objectives were categorized into seven policy domains relevant to food systems: agriculture, environment, social protection, health, land, education, economic development, and rural development. Of the ninety-one policies reviewed from 1947-2017, six were identified as being "overarching" with goals across all the domains. About half of the policies focused on agriculture and the environment, reflecting an emphasis on agricultural production. Policies were formulated and implemented in silos. As a result, learning from implementation, and adjusting to improve impact has been limited. Particularly important is that coordination during implementation, across these complex domains, has been partial. In order to achieve its stated food and nutrition outcomes, including Sustainable Development Goal (SDG) 2, South Africa needs to translate its policies into tangible, practical plans and processes guided by effective coordination and alignment. Key recommendations are practically to align policies to a higher-level "food goal", establish better coordination mechanisms, consolidate an effective monitoring and evaluation approach to address data gaps and encourage learning for adaptive implementation. Actively engaging the existing commitments to the SDGs would draw stated international commitments together to meet the constitutional commitment to food rights into an overarching food and nutrition security law.

The contribution of breastfeeding to a healthy, secure and sustainable food system for infants and young children: monitoring mothers' milk production in the food surveillance system of Norway

OBJECTIVE

The mother-child breastfeeding dyad is a powerful force for achieving healthy, secure and sustainable food systems. However, food system reports exclude breastfeeding and mother's milk. To help correct this omission and give breastfeeding women greater visibility in food systems dialogue and action, we illustrate how to estimate mother's milk production and incorporate this into food surveillance systems, drawing on the pioneering experience of Norway to show the potential value of such analysis.

DESIGN

The estimates use data on the proportion of children who are breastfed at each month of age (0-24 months), annual number of live births and assumptions on daily human milk intake at each month. New indicators for temporal and cross-country comparisons are considered.

SETTING

It is assumed that a breastfeeding mother on average produces 306 l of milk during 24 months of lactation.

PARTICIPANTS

The annual number of live births is from Statistics Norway. Data for any breastfeeding at each month of age, between 0 and 24 months, are from official surveys in 1993, 1998-1999, 2006-2007, 2013 and 2018-2019.

RESULTS

Estimated total milk production by Norwegian mothers increased from 8·2 to 10·1 million l per year between 1993 and 2018-2019. Annual per capita production increased from 69 to 91 l per child aged 0-24 months.

CONCLUSIONS

This study shows it is feasible and useful to include human milk production in food surveillance systems as an indicator of infant and young child food security and dietary quality. It also demonstrates significant potential for greater milk production.

Perception versus reality of the COVID-19 pandemic in U.S. meat markets

Disruptions to meat markets during the COVID-19 pandemic spurred mass media attention. While media deeming the U.S. food system 'broken' garnered a great deal of attention, the actual production and meat availability data does not support this conclusion. The U.S. meat supply chain, while certainly strained and with measurable consequence during periods of adjustment, proved ultimately resilient and rebounded quickly. Increased attention on meat supply chains may drive continued efforts to improve resiliency, but analyses of online media and U.S. production and cold storage data do not support a narrative that the system 'broke', but was perhaps 'strained' and 'responded efficiently'. Findings indicate that public sentiment about U.S. meat supply overall was not as dominated by pandemic-era concerns as may be hypothesized.

The role of dairy in healthy and sustainable food systems: community voices from India

Background

Managing the role of dairy foods in healthy and sustainable food systems is challenging. Milk production is associated with greenhouse gas emissions and milk-based processed foods can be high in fat, sugar and salt; yet, milk production provides income generating opportunities for farmers and dairy foods provide essential nutrients to young children, with a cultural significance in many communities. This is particularly relevant to India, the world’s largest producer of milk. The aim of this study was to use Photovoice, a participatory research method, to explore the experiences and perceptions of communities in India on the role of dairy products in local sustainable and healthy food systems.

Methods

Purposive sampling recruited two women’s self-help groups in Visakhapatnam, Andhra Pradesh: one in a rural area and one in an urban area. A total of 31 participants (10–17 urban group and 12–14 rural group), produced photographs with captions to represent their views on how dairy was produced, sold, and consumed in their community. A discussion workshop was held in each area, with prompts to consider health and the environment. Workshop transcripts, photographs and captions were analysed qualitatively using thematic analysis.

Results

A range of experiences and perceptions were discussed by the two women’s self help groups. Participants had an awareness of their local food system and how stages of dairy food supply chains were non-linear and inherently interconnected. Three main themes were identified: 1) Quality and value matters to producers and consumers; 2) The need to adapt to sustain dairy farmer livelihoods in water scarce areas; 3) It’s not only about health.

Conclusions

Moderate milk-producing states such as Andhra Pradesh will continue to develop their dairy industry through policy actions. Including communities in policy discussions through innovative methods like Photovoice can help to maximise the positive and minimise the negative role of dairy in evolving local food systems.

Consumer experiences of food environments during the Covid-19 pandemic: Global insights from a rapid online survey of individuals from 119 countries

This study investigates consumer experiences of food environments and food acquisition practices during the Covid-19 pandemic. Our rapid assessment online survey featured a convenience sample of 2015 individuals from 119 countries, spanning Western Europe, North America, Latin America, Asia-Pacific, and Africa. Data collection took place in April 2020 during the second month of the pandemic. Participants were recruited via existing networks of the United Nations System Standing Committee on Nutrition, through social media, and by snowballing. The majority of participants were female (71.9%), from low- and middle-income countries (51.0%), and working in nutrition or healthcare (39.3%). Qualitative thematic analysis and descriptive statistics reveal a series of common global experiences related to food availability and accessibility, food prices and affordability, food acquisition practices, and food preparation and consumption. The importance of community food participation, food sharing, and resource allocation are highlighted, along with increasing awareness of healthy diets and food waste. We identify ten synergistic policy entry points to: 1) build resilient and equitable food environments resistant to stresses and shocks; 2) harness positive dietary-related behaviors manifested during the pandemic; and, 3) mitigate the projected nutrition crisis and promote sustainable healthy diets for all.

Barriers and Enablers for Healthy Food Systems and Environments: The Role of Local Governments

Purpose of review

Food systems at all levels are experiencing various states of dysfunction and crisis, and in turn their governance contributes to other intensifying crises, such as climate change, biodiversity loss and the rapid expansion of dietary-related non-communicable diseases. In many jurisdictions governments at local, state and national levels are taking action to tackle some of the key challenges confronting food systems through a range of regulatory, legislative and fiscal measures. This article comprises a narrative review summarising recent relevant literature with a focus on the intersection between corporate power and public health. The review sought to identify some of the principal barriers for the design and support of healthy food systems and environments, as well as key reforms that can be adopted to address these barriers, with a focus on the role of local governments.

Recent findings

The review found that, where permitted to do so by authorising legislative and regulatory frameworks, and where political and executive leadership prioritises healthy and sustainable food systems, local governments have demonstrated the capacity to exercise legislative and regulatory powers, such as planning powers to constrain the expansion of the fast food industry. In doing so, they have been able to advance broader goals of public health and wellbeing, as well as support the strengthening and expansion of healthy and sustainable food systems.

Summary

Whilst local governments in various jurisdictions have demonstrated the capacity to take effective action to advance public health and environmental goals, such interventions take place in the context of a food system dominated by the corporate determinants of health. Accordingly, their wider health-promoting impact will remain limited in the absence of substantive reform at all levels of government.

Gardening can relieve human stress and boost nature connection during the COVID-19 pandemic

The COVID-19 pandemic has severely disrupted social life. Gardens and yards have seemingly risen as a lifeline during the pandemic. Here, we investigated the relationship between people and gardening during the COVID-19 pandemic and what factors influenced the ability of people to garden. We examined survey responses (n = 3,743) from gardeners who reported how the pandemic had affected personal motivations to garden and their use of their gardens, alongside pandemic-related challenges, such as food access during the first wave of COVID-19 (May-Aug 2020). The results show that for the respondents, gardening was overwhelmingly important for nature connection, individual stress release, outdoor physical activity and food provision. The importance of food provision and economic security were also important for those facing greater hardships from the pandemic. While the literature on gardening has long shown the multiple benefits of gardening, we report on these benefits during a global pandemic. More research is needed to capture variations in public sentiment and practice - including those who do little gardening, have less access to land, and reside in low-income communities particularly in the global south. Nevertheless, we argue that gardening can be a public health strategy, readily accessible to boost societal resilience to disturbances.

Extraction and detection methods of microplastics in food and marine systems: A critical review

The ubiquitous presence of microplastics as contaminants in the ecosystem has become a matter of environmental concern gaining considerable attention in the research community as well as public arena. Lack of efficient collection and improper management of plastic have resulted in the enormous amounts of plastic wastes landing into the marine systems with oceans being the ultimate sink. Due to non-biodegradability, these plastics break down into smaller fragments over a period of time leading to consumption by aquatic species, threatening marine life. In the recent years, a wide range of food products has also been contaminated with microplastics directly affecting human health. This review focuses on the separation and identification technologies for extraction and detection of microplastics in food and marine ecosystems. Efficient technologies like floatation, membrane separation, chemical treatment, enzymatic treatment, and other miscellaneous techniques have been discussed considering their merits and demerits. Additionally, identification technologies like optical detection, scanning electron microscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, thermo-analytical methods, and hyperspectral imaging have been emphasized for the detection of microplastic particles. The emerging techniques like enzymatic digestion combined with hyperspectral imaging could be a possible way for obtaining higher separation efficiency and characterization with minimal harm to food sample. This article narrows the gap for choosing a standard separation technology for microplastic detection in food matrices keeping in mind the composition, particle size, shape, data visualization techniques and cost.

Fixes that Fail: A system archetype for examining racialized structures within the food system

Access to fresh and healthy food within a neighborhood has been identified as a social mechanism contributing to community health. Grounded in the understanding that challenges related to equity within a food system are both structural and systemic, our research demonstrates how systems thinking can further understandings of food system complexity. Within systems thinking, we provide an illustration of how system archetypes offer an analytic tool for examining complex community issues. We map semi-structured interview data from community stakeholders (N = 22) to the "Fixes that Fail" system archetype to illuminate systemic challenges, such as incarceration and poverty, that structure food system inequity in urban communities. Within our research, the "Fixes that Fail" archetype provided a narrative interpretive tool for unveiling complexity within the food system and interdependencies with racialized systems such as criminal justice and labor markets. This system archetype provided an accessible approach for generating narratives about systemic complexity, the production of inequity through racialized forces, and opportunities for transformation.

Re-imagining the UN Committee on World Food Security

This article argues that the United Nations Committee on World Food Security can and must serve as a space for catalyzing and strengthening public interest-oriented food systems governance grounded in the human rights framework. This would necessarily entail confronting the fragmentation of governance and erasure of accountability promoted by corporate designed multi-stakeholderism, and democratizing multilateralism through genuine participation of rights holders, public scrutiny and participatory science. Pivotal to this endeavor is arresting the growing corporate influence in governance mechanisms and reorienting them towards reinvigorating relationships among people, communities and governments.

Women's dual centrality in food security solutions: The need for a stronger gender lens in food systems' transformation

Food insecurity remains a critical issue worldwide. The current COVID-19 crisis has exposed how vulnerable the global food systems are and that urgent measures need to be taken, especially in the Global South. Despite increased recognition that women are among the most food insecure yet major contributors to local and global food security over the recent years, there has not been a systemic change needed in the current food security paradigm. This paper argues that, in developing countries, a stronger gender lens ought to be at the center to the food systems' debate as women are critical to agriculture and food systems' sustainability and resilience. Women are central to food systems, both as primary food producers and as primary caretakers of the household. Three key recommendations are put forward in this article for establishing inclusive, sustainable and resilient food systems: One, ensuring a stronger gender lens in food systems and food security paradigms; by working with accurate sex-disaggregated data and beyond on individuals' level. Two, promoting and supporting alternative strategies to agriculture as a means of livelihood for women. Three, ensuring that women are central in food security solutions by not only listening to their concerns and needs, but also building on their resilience, knowledge, and practices.

Local urban government policies to facilitate healthy and environmentally sustainable diet-related practices: a scoping review

OBJECTIVE

This scoping review sought to describe the policy actions that urban local governments globally have implemented to facilitate healthy and environmentally sustainable diet-related practices.

SETTING

Urban local government authorities.

DESIGN

Five databases were searched to identify publications which cited policies being implemented by local governments within the 199 signatory cities of the Milan Urban Food Policy Pact (MUFPP) that targeted at least one healthy and sustainable diet-related practice. Grey literature was then searched to retrieve associated policy documentation. Data from both sources were charted against the MUFPP's monitoring framework to analyse the policy actions included in each overarching policy.

RESULTS

From 2624 screened peer-reviewed studies, 27 met inclusion criteria and cited 36 relevant policies amongst signatory cities to the MUFPP. Most were from high income countries (n 29; 81 %), considered health (n 31; 86 %), equity (n 29; 81 %) and the broader food system beyond dietary consumption (n 34; 94 %). Of the 66 policy actions described, the most common involved food procurement within public facilities (n 16; 44 %) and establishing guidelines for school-feeding programs (n 12; 33 %).

CONCLUSIONS

This review has demonstrated that urban local government authorities are implementing policies that consider multiple phases of the food supply chain to facilitate population-wide uptake of healthy and sustainable diet-related practices. Opportunities exist for local governments to leverage the dual benefits to human and planetary health of policy actions, such as those which discourage the overconsumption of food including less meat consumption and the regulation of ultra-processed foods.

The food system and climate change: are plant-based diets becoming unhealthy and less environmentally sustainable?

A plant-based diet, which can include small amounts of meat, is the foundation for healthy sustainable diets, which will have co-benefits for health, climate and the environment. Studies show that some of the barriers to making this dietary change and reducing meat consumption are perceptions that plant-based diets are inconvenient, it takes too much time and skills to prepare meals and ingredients are expensive. The food environment is changing and the industry is responding with the exponential increase in the market of highly processed, convenient and cheap plant-based foods. This overcomes some of the barriers, but there is concern about whether they are healthy and environmentally sustainable. Plant-based foods have a halo effect around health and the environment, but many being produced are ultra-processed foods that are high in energy, fat, sugar and salt and have a higher environmental impact than minimally processed plant-based foods. The trend towards eating more highly processed plant-based convenience foods is a concern with regard to both public health and the targets set to reduce greenhouse gas (GHG) emissions. The 'modern day' plant-based diet emerging is very different to a more traditional one comprising pulses, vegetables and wholegrain. Studies show that those who are younger and have been a vegetarian for a shorter duration are eating significantly more ultra-processed plant-based foods. While there is a place for convenient, desirable and affordable plant-based food to encourage dietary change, care should be taken that this does not subconsciously set a path which may ultimately be neither healthy nor sustainable.

The future of human malnutrition: rebalancing agency for better nutritional health

The major threat to human societies posed by undernutrition has been recognised for millennia. Despite substantial economic development and scientific innovation, however, progress in addressing this global challenge has been inadequate. Paradoxically, the last half-century also saw the rapid emergence of obesity, first in high-income countries but now also in low- and middle-income countries. Traditionally, these problems were approached separately, but there is increasing recognition that they have common drivers and need integrated responses. The new nutrition reality comprises a global ‘double burden’ of malnutrition, where the challenges of food insecurity, nutritional deficiencies and undernutrition coexist and interact with obesity, sedentary behaviour, unhealthy diets and environments that foster unhealthy behaviour. Beyond immediate efforts to prevent and treat malnutrition, what must change in order to reduce the future burden? Here, we present a conceptual framework that focuses on the deeper structural drivers of malnutrition embedded in society, and their interaction with biological mechanisms of appetite regulation and physiological homeostasis. Building on a review of malnutrition in past societies, our framework brings to the fore the power dynamics that characterise contemporary human food systems at many levels. We focus on the concept of agency, the ability of individuals or organisations to pursue their goals. In globalized food systems, the agency of individuals is directly confronted by the agency of several other types of actor, including corporations, governments and supranational institutions. The intakes of energy and nutrients by individuals are powerfully shaped by this ‘competition of agency’, and we therefore argue that the greatest opportunities to reduce malnutrition lie in rebalancing agency across the competing actors. The effect of the COVID-19 pandemic on food systems and individuals illustrates our conceptual framework. Efforts to improve agency must both drive and respond to complementary efforts to promote and maintain equitable societies and planetary health.

Ghana's rice value chain resilience in the context of COVID-19

The 2020 State of the Food Security and Nutrition World report suggests that the COVID-19 pandemic may render 83 to 132 million people food insecure. The global south has been projected to be adversely affected by COVID-19 in terms of food and nutritional security. This potentially renders Africa off track in achieving SDG -2 of zero hunger by 2030. Ghana is a net importer of rice and how the sector responded to the global pandemic has received less traction in the agri-food system literature. There is skewed literature that concentrates on the global north. The paper employed a qualitative approach involving key informant interviews across 6 regions in Ghana. The study covered 48 Agricultural Extension Agents (AEAs) and Monitoring and Evaluation (M&E) officers, 80 farmers, and 48 market leaders. We use one of the country's main food staple - rice to show the food (in)-security situation during the pandemic. We articulate that using the right food security conceptual and theoretical framing remains imperative in understanding food (in)-security. The findings showed price hikes during the imposition of lockdown affected access (physical and effective demand). Rice however remained available during and after the lockdown imposition. Ghana's rice production output was affected during the COVID-19 pandemic in 2020. The ramification of COVID-19 on Ghana's rice sector was not dire but points to the vulnerability of the rice value chain to future pandemics. Important policy actions are needed to consolidate particular gains made in Ghana's planting for food and jobs to minimize rice imports.

Crisis, transformation, and agency: Why are people going back-to-the-land in Greece?

Transformations are fundamentally about agency: human intention, motivation, and power to influence and to resist. Most studies focus on deliberate system-level transformations, usually guided by a set of influential actors. However, system-level transformations may also occur as the result of the cascading effects of multiple individual transformations in response or in anticipation to various crises. Little is known about how crises foster these individual transformations, and how these may relate to different types of system-level change. This article fills this gap by looking at how crisis fosters two different types of agencies-internal and external-and how these link to individual transformations in the case of Greece's back-to-the-land movement whereby urbanites sought to reconnect with land-based livelihoods during the economic crisis (2008 onwards). The article draws on the qualitative analysis of 76 interviews of back-to-the-landers to further understand why people are going back-to-the-land (their motivations), how these relate to the concept of agency and individual transformation, and what implications might there be for system-level social-ecological transformations. This article makes three key points. First, crises create different opportunity contexts that may lead to rapid changes in what is valued in the broader social discourse. While social values and discourses are usually considered to be "deep levers" and slow to change, we found that they can rapidly shift in times of crises, challenging notions of the role of fast vs. slow variables in system transformations. Second, agency is needed to respond to crises but is also further catalyzed and enhanced through crisis; activating one's internal agency leads to personal transformations as well as collective transformations (linked to external agency), which are mutually co-constitutive. And third, systemic-level transformation emerges through multiple pathways including through the aggregation of multiple individual transformations that may lead to emergent system-level changes.
