Food supply chains hold significant embodied carbon emissions that need to be mitigated and neutralized. This study aimed to explore the historical Greenhouse Gas (GHG) emissions associated with household food consumption at a local scale i.e. across the eight English regions and the four nations that comprise the United Kingdom (UK). UK EatWell guidelines were used to explore the potential change in emissions and food costs in a scenario of transitions to healthier diets across the study areas. These emissions were calculated based on food consumption data before the advent of the Covid-pandemic i.e. between the years 2001 and 2018. Spatial data analysis was used to explore if the study areas had any significant correlations with respect to the emissions during the study period. The results displayed a potential reduction in GHG emissions for all study areas in the explored scenario. Further impacts include a reduction in household food costs across a majority of the areas during the study period. However, a consistent trend of significant correlations among the study areas was absent. This study concludes that local or regional policymaking should take precedence over national regulations to achieve healthier diets that are both carbon-neutral and affordable for the households.

Summary: Web 3.0 and artificial intelligence (AI) have presented unprecedent impact on the food sector. However, there is no clear scientific description yet related to their influences on food safety, quality and traceability across the meat supply chain. This study systematically reviews the available data pertaining to Web 3.0 and related novel technologies, their possible use in the meat supply chain and their confluent effect on meat safety. This systematic review followed the PRISMA methodology. The articles selected were identified by searching three databases: Scopus, Web of Science and PubMed. The search results showed that the meat industry and the meat supply chain have their share of positive implications instigated by Web 3.0 technologies. Web 3.0 technologies are shown to be effective for the food safety of meat from farm to fork, particularly in inspection and quality assessment with blockchain integration enhancing transparency and traceability with innovative approaches promising to improve meat safety, increase profitability, efficiency, scalability and modularisation of meat manufacturing in addition to better adherence to animal welfare increasing thus consumer's confidence. Further research is still, needed to examine the role of such technologies at the level of other parts of the supply chain including the pre‐processing step, processing and packaging.

Retail distribution is essential for the growth of markets for local food. While online direct‐to‐consumer and local food hubs are becoming more sophisticated, the largest market for local foods remains the traditional intermediation (retailing) sector. We develop an agent‐based model to simulate the expansion, growth and profitability of retailers offering local foods across a landscape populated by consumers and competing retailers. We design a series of experiments to examine how changes in prices and assortment that include local and non‐local options in the fresh produce category impact store market share and profitability. We validate the model, and conduct our experiments, using household fresh produce expenditures data from a retail food‐delivery business in the Mid‐Atlantic region of the US. We find that retailers offering a larger assortment of local foods are able to sustain higher basket‐average retail prices and exhibit higher long‐run profits in comparison to retailers that do not carry local options. These results underscore the importance of local foods in a food retailer's price and assortment strategy. The key implication is that retailers need to be conscious not only of the breadth but also of the quality of their assortment in their pricing strategies. [ABSTRACT FROM AUTHOR]

Societal Impact Statement: Political interests and power structures shape state‐led crop conservation and food policy. As a crop that relates to culture and belonging, the chile crop is ideal for exploring how food security policy and crop conservation schemes integrate aspects beyond staple crops, calories and/or electoral incentives. What do these schemes mean for the food and ingredients we love? Reflecting from this perspective can be useful to grasp, re‐frame and create more effective and inclusive food policies—ones that embody and valorise flavour, identities and territories beyond statements on paper. Summary: In line with the Food and Agriculture Organisation's (FAO) international action plan for crop genetic resources, the Mexican state inaugurated the National System of Genetic Resources for Food and Agriculture (SINAREFI) in 2002. In this paper, I explore SINAREFI's interest in landraces and in situ conservation through the case of chile pepper, set under the Ministry of Agriculture's interests of promoting industrial agriculture and paternalistic food security welfare programmes.Through the analyses of existing literature on food security in Mexico state programmes, archival work and interviews, this article analyses how discourses on food security shape research trajectories, some of which are inevitably constrained by current market‐based agricultural systems.By exploring the state's chile research and conservation programme, this work demonstrates the complexity of international food security discourse and its application domestically. Particularly, this analysis highlights the limitations of state crop research and conservation efforts imposed by contradictory agricultural policies. In the case of chile, its link to Mexican culture and diet uncovers an important, but often overlooked, aspect of food security: flavour.In the case of chile, a non‐staple but culturally symbolic crop, welfare programmes remained paternalistic and focused on caloric intake despite the transformation of national discourse on food security towards the integration of landraces and local cultures through the inauguration of SINAREFI. This case study reflects on the limits of current framings and strategies regarding food security and the need to direct policies towards local food sovereignty to achieve the necessary stability for food security to endure.

The affordances offered by digital platforms may support the formation and maintenance of moralized markets – defined as markets that are undergirded with explicit moral principles that guide the interactions between market actors. In this paper, we draw on key tenets from recent advances in affordance theory, identifying social media platform affordances that support the moralization of digital markets. We develop insights based on qualitative data from the context of Norwegian digital local food markets, with focus on the role of digital affordances. We theorize particular 'moral affordances' that matter in the moralization of markets. We conclude by considering the possible outcomes that the increasing use of digital platforms may have for the moralization of contemporary markets. [ABSTRACT FROM AUTHOR]

The modern global food system is highly unsustainable, shaped by industrialisation and corporate consolidation, with negative repercussions on the environment and biodiversity as well as human health. This paper looks at the burgeoning economy in neglected and underutilised species (NUS) in the Western Cape, South Africa, as a potential innovation that could make the local food system more socially and ecologically resilient. Although, at present, NUS are only marginally included in the local food system and policy discussions, NUS increasingly appear in the high-end food industry, driven by international gastronomic trends. These species hold potential as climate resilient, nutritionally dense, and socially and culturally significant foods in the region, but they also carry ecological and social risks. We critically examine the fledgling NUS economy in the Cape Town area to unpack the motivations and challenges associated with the potentially transformative inclusion of these foods into the local food system. We demonstrate that the main risks associated with NUS are negative ecological repercussions, privatisation of the NUS economy, and the reproduction and further entrenchment of unequal power and race dynamics in the region. To mitigate these risks and actualise the related benefits associated with NUS, engagement with the ecological, social, and political context of NUS needs to be significantly deepened. This is particularly true for those working in the high-end food industry, who appear to be driving the NUS economy, and will require education around sustainability and Traditional Ecological Knowledge (TEK), as well as a foregrounding awareness of power dynamics.

Local food systems can have economic and social benefits by providing income for producers and improving community connections. Ongoing global climate change and the acute COVID-19 pandemic crisis have shown the importance of building equity and resilience in local food systems. We interviewed ten stakeholders from organizations and institutions in a U.S. midwestern city exploring views on past, current, and future conditions to address the following two objectives: 1) Assess how local food system equity and resilience were impacted by the COVID-19 pandemic, and 2) Examine how policy and behavior changes could support greater equity and resilience within urban local food systems. We used the Community Capitals Framework to organize interviewees' responses for qualitative analyses of equity and resilience. Four types of community capital were emphasized by stakeholders: cultural and social, natural, and political capital. Participants stated that the local food system in this city is small; more weaknesses in food access, land access, and governance were described than were strengths in both pre- and post-pandemic conditions. Stakeholder responses also reflected lack of equity and resilience in the local food system, which was most pronounced for cultural and social, natural and political capitals. However, local producers' resilience during the pandemic, which we categorized as human capital, was a notable strength. An improved future food system could incorporate changes in infrastructure (e.g., food processing), markets (e.g., values-based markets) and cultural values (e.g., valuing local food through connections between local producers and consumers). These insights could inform policy and enhance community initiatives and behavior changes to build more equitable and resilient local food systems in urban areas throughout the U.S. Midwest.

Regional food is grounded in local practices and heritage. With industrialization and post-green revolution threat to food produced within specific region and the associated knowledge has become imminent. Scholars have analyzed the revival of regional foods in different parts of the world. However, there have been limited studies focusing on the revival of regional food from the perspective of food as commons. The paper fills this gap by analyzing the efforts of Morarka-GDC Foundation along with farmers collective in Nawalgarh, India. Employing the framework of commons, we examine how the foundation along with the collective is reviving Shekhawati region's foods. We used primary and secondary sources to capture the social activities undertaken to sustain the commons. It was found that adopting organic agricultural practices helped in reviving the regional foods by creating and using stock of local resources. Further, social dilemma associated with culinary commons was avoided by creating networks between producers and consumers through Shekhawati festival and Morarka Organics. These practices have resulted in rebuilding the local food system, local tourism, and intergenerational transmission strengthening the local gastronomic identity. However, linking regional food with gastronomic tourism can threaten the local gastronomic culture and survival of authentic regional food. We also find that for a sustained management of the regional foods, scaling-up plays an essential role which has further limitations. [ABSTRACT FROM AUTHOR]

In the last 2 decades, the literature has documented the upsurge of community-driven processes of consumer-producer cooperation, which are alternative to the dominant food system. These organizational arrangements have been conceptualized differently, witnessing the growing importance of local communities in generating place-based solutions to the demand for organic, local, and sustainable food. Relying on a practice theory approach, this article delves into two key inquiries: first, what motivates individuals to become part of Civic Food Networks (CFNs) and how does this influence the variety of food entering their households? And second, how does participation in a CFN impact people's daily food practices, with a particular focus on diet diversification? We employ the term "civic food networks (CFN)" to underscore the significance of grassroots initiatives in the broader context of local food policies. This term also highlights the connections to other movements known for their potential for transformation, such as the solidarity economy, transition towns, and de-growth movements. Our analysis draws on a comprehensive qualitative approach, which includes participant observation, in-depth interviews, and a focus group involving members of the CSA Naturalmente in Trentino, situated in the North-Eastern part of Italy. The findings reveal that altering dietary habits poses various challenges both at the individual and institutional levels. This process involves the stabilization of ingrained habits, adjustments to daily routines, and the reinforcement of shared norms. Furthermore, it underscores the critical role of food policies in promoting sustainable eating practices. [ABSTRACT FROM AUTHOR]

The identity of women entrepreneurs illuminates discursive struggles given the masculine norms of entrepreneurship. Applying relational dialectics theory (RDT), this study explored competing discourses surrounding understudied Chinese women entrepreneurs and the interplay of their identification and masculine discourses. I conducted narrative interviews with 34 Chinese women. Contrapuntal analysis of this non-Western data however identified that discursive struggles happened when voicing/speaking/expressing was not prioritized. Hence, I turned to new materialist perspectives to (re)work discourses as boundary-making practices producing local things/beings-in-relations and agents as anyone/anything participating in the dynamism. In two themes as competing discourses (discourses of misalignment vs. legitimacy), I focused on local movements and interferences when/where women in their entrepreneurial becoming encountered various human and nonhuman agents, and therefore demonstrated how discursive struggles involved various bodies/things, more than just talk/voices. Ultimately, this study diffracted RDT by engaging with new materialisms and proposing a new uttered-embodied dimension of discursive struggles. [ABSTRACT FROM AUTHOR]

Like many Mediterranean areas, the Italian island of Sicily faces multiple environmental pressures such as soil loss, fire hazards, and extreme meteorological events, all of which negatively impact local food systems. In response to these threats, a re-thinking of local agriculture and natural resource management is increasingly needed. Agroecology is recognized as a robust proposal for building more resilient food systems grounded in farmers' knowledge and practices. However, agroecological farming experiences struggle to operate and survive in Sicily due to unfavorable political-cultural, environmental, and socio-economic conditions. Learning from small-scale farmers about the ways they perceive, understand, and overcome structural limits and environmental constraints is key for a transition to agroecology in the study area. Understanding its potentials and limits is essential for planning and identifying transformative actions. We approached the problem by adopting a participatory action research methodology involving selected groups of farmers in Western Sicily. We applied a co-creative approach and developed a systemic analysis of the socio-ecological narratives to identify possible leverage points for a transition to agroecology in the study area. We identified a local potential for shifting the current system of water and fire hazards management to new systems of participatory land stewardship. To be effective, these systems should support agroecological farmers' income by altering social practices related to food and reducing the influence of dominant agribusiness actors. Our findings indicate that implementing solutions based on the circulation of local ecological knowledge within systems of participatory guarantees can favor the development of solidarity economies and mutualistic relations between farmers, scientists, and communities. Our work suggests that scientists' facilitation and knowledge cocreation might be of key importance in structuring local, more sustainable food systems. [ABSTRACT FROM AUTHOR]

Despite (or perhaps because of) the staggering scale and pace of global change, the concept of the Anthropocene eludes discrete classification. There is widespread consensus that conditions associated with the Anthropocene, including rapid biodiversity loss and climate change, must be addressed if we are to enjoy ongoing and rich experiences. At the crux of human impacts is urban living as of 2024 nearly 60% of people live in cities. Human societies are tightly interconnected with each other and surrounding ecosystems, but for citydwellers, these connections may seem abstract. A failure to appreciate and foster such connections can have human and environmental health repercussions. We present a concept for a meal featuring local wild foods that could only be appropriately served under regionally ameliorated Anthropocene conditions. By presenting this hypothetical "solution", we seek a common ground that spans human (and non-human) cultures and behaviors, and a concept that can be extended to any community. The simplicity of the "Anthropocene meal" belies three primary challenges: improvements to urban design, maintenance of ecosystem health, and shifting cultural attitudes. However, these barriers are quantifiable and may be addressed within annual to decadal timelines, making the Anthropocene meal a broadly achievable goal, and thus a valid source of optimism in a time of great uncertainty.

Background: Food insecurity, an economic and social condition of limited food access, is associated with poor diet quality—a risk factor for several common cancers. The University of Texas MD Anderson Cancer Center supports healthy food access through community‐led evidence translation by actively partnering with community‐based organizations (CBOs). These partnerships aim to enhance the capacity of food assistance CBOs to effectively implement evidence‐based food insecurity mitigation programs in the cancer center's area of influence. Methods: This case study aims to describe the cancer center's model for local food access capacity building and detail operationalization in the context of a whole‐community cancer prevention effort (Be Well Baytown) in Baytown, Texas. Results: Elements central to the capacity building model include (i) assessment of baseline needs and capacity, (ii) empowering a community champion within a relevant CBO, (iii) mapping inter‐sectoral community partnerships, collaborations, and linkages, and (iv) leveraging systems, connections, and resources to provide an enabling environment for overall food access systems growth. Through this process, Be Well Baytown enhanced the capacity of a local food pantry leading to increases in total reach, pounds of food distributed, and number of food distribution events in collaboration with intersectoral partners from 2018 to 2023. Conclusion: This case study highlights the model's implementation as a co‐benefit community partnership strategy to maximize the impact of food security programs integrated with comprehensive cancer center prevention efforts. The purpose of this case study is to summarize learning from supporting food assistance CBOs to effectively implement evidence‐based food insecurity mitigation programs and to better understand how to optimize use of community‐driven food security programs aligned to Comprehensive Cancer Center's (CCC) community outreach and engagement (COE) efforts. The case study demonstrates a successful community partnership strategy integrating food security programs into comprehensive cancer prevention efforts that improved the capacity of a local food pantry, resulted in expanded reach, increased food distribution, and more collaborations with partners from 2018 to 2023 offering a model for other CCCs.

Background: Addressing Indigenous food security and food sovereignty calls for community-driven strategies to improve access to and availability of traditional and local food. Participatory approaches that integrate Indigenous leadership have supported successful program implementation. Learning Circles: Local Healthy Food to School is a participatory program that convenes a range of stakeholders including food producers, educators and Knowledge Keepers to plan, implement and monitor local food system action. Pilot work (2014–2015) in Haida Gwaii, British Columbia (BC), showed promising results of the Learning Circles (LC) approach in enhancing local and traditional food access, knowledge and skills among youth and adolescents. The objective of the current evaluation was therefore to examine the process of scaling-up the LC vertically within the Haida Nation; and horizontally across three diverse First Nations contexts: Gitxsan Nation, Hazelton /Upper Skeena, BC; Ministikwan Lake Cree Nation, Saskatchewan; and Black River First Nation, Manitoba between 2016 and 2019. Methods: An implementation science framework, Foster-Fishman and Watson's (2012) ABLe Change Framework, was used to understand the LC as a participatory approach to facilitate community capacity building to strengthen local food systems. Interviews (n = 52), meeting summaries (n = 44) and tracking sheets (n = 39) were thematically analyzed. Results: The LC facilitated a collaborative process to: (1) build on strengths and explore ways to increase readiness and capacity to reclaim traditional and local food systems; (2) strengthen connections to land, traditional knowledge and ways of life; (3) foster community-level action and multi-sector partnerships; (4) drive actions towards decolonization through revitalization of traditional foods; (5) improve availability of and appreciation for local healthy and traditional foods in school communities; and (6) promote holistic wellness through steps towards food sovereignty and food security. Scale-up within Haida Gwaii supported a growing, robust local and traditional food system and enhanced Haida leadership. The approach worked well in other First Nations contexts, though baseline capacity and the presence of champions were enabling factors. Conclusions: Findings highlight LC as a participatory approach to build capacity and support iterative planning-to-action in community food systems. Identified strengths and challenges support opportunities to expand, adopt and modify the LC approach in other Indigenous communities with diverse food systems. [ABSTRACT FROM AUTHOR]

Dispersal among local communities is fundamental to the metacommunity concept but is only important to the metacommunity structure if dispersal causes distortions of species abundances away from what local ecological conditions favour. We know from much previous work that dispersal can cause such abundance distortions. However, almost all previous theoretical studies have only considered one species alone or two interacting species (e.g. competitors or predator and prey). Moreover, a systematic analysis is needed of whether different dispersal strategies (e.g. passive dispersal versus demographic habitat selection) result in different abundance distortion patterns, how these distortion patterns change with local food web structure, and how the dispersal propensities of the interacting species might evolve in response to one another. In this article, we show using computer simulations and analytical models that abundance distortions occur in simple food webs with both passive dispersal and habitat selection, but habitat selection causes larger distortions. Additionally, patterns in the evolution of dispersal propensity in interacting species are very different for these two dispersal strategies. This study identifies that the dispersal strategies employed by interacting species critically shape how dispersal will influence metacommunity structure. This article is part of the theme issue 'Diversity-dependence of dispersal: interspecific interactions determine spatial dynamics'. [ABSTRACT FROM AUTHOR]

Background: Current local food environments encourage poor diets, posing a significant threat to public and planetary health. Acknowledging and addressing its inherent complexity is vital to making meaningful improvements to the food environment. Using a participatory approach with local stakeholders, this study aims to gain insight into the factors and mechanisms underlying the local food environment and to identify leverage points and system-based actions to foster healthy and sustainable local food environments. Methods: A systems-thinking approach was used in a Dutch municipality in 2022. Two group model building (GMB) workshops were held with community stakeholders (e.g. local policymakers, retailers and residents). During the first workshop (June 2022), factors and mechanisms influencing the local food environment were identified and visualized through a causal loop diagram (CLD). During the second workshop, leverage points and system-based actions to improve food environments were identified by the stakeholders. Four months after (October 2022), an action-implementation meeting was organized to stimulate the implementation of selected actions. Progress was monitored through brief telephone interviews 6 and 12 months after the second workshop. Results: The CLD visualises the factors and mechanisms influencing the local food environment from the point of view of the community stakeholders. The CLD consists of 46 factors shaping the local food environment, which were categorized into four identified subsystems: societal factors, individual, socio-economic factors, commercial factors and political factors. Eight leverage points were identified within the CLD, for example, 'lobby from food industry', 'governmental food policies' and 'e-commerce and platform economy'. Stakeholders formulated 20 actions targeting the identified leverage points. During the action-implementation meeting, long-term plans were created for five actions. After 1 year, only one participant (policy advisory role) remained actively engaged in three of these actions. Conclusions: This study yields insight into the numerous factors and mechanisms underlying the local food environment and identified system-based actions as perceived by local stakeholders to improve this food environment locally. The CLD offers stakeholders valuable insights on employing a systems approach when enhancing food environments. More research is necessary, especially into the long-term processes and effects of implementing system-oriented actions to improve local food environments. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusions To improve the healthfulness of foods offered while accelerating the use of environmental sustainability practices, it is important to engage hospital food service operators in the adoption of such practices. The purpose of this study was to explore barriers, facilitators and best practices for implementing environmental sustainability standards in food service among veterans affairs (VA) hospitals in the United States.We conducted an online survey with 14 VA hospital food service directors and then 11 qualitative interviews. The survey assessed motivations for initiating sustainability standards and included a self‐rating of implementation for each of five standards: increasing plant‐forward dishes, procuring and serving sustainable foods that meet organic/fair trade and other certifications, procuring and serving locally produced foods, reducing food waste and reducing energy consumption. Interviews were transcribed verbatim. Qualitative analysis, including coding of themes and subthemes, was conducted by two coders to determine barriers, facilitators and best practices for each of these five standards. Quantitative methods (counts and frequencies) were used to analyse the survey data.Participants had an average of 5 years of experience implementing sustainability standards. The top three motivators cited were reducing food waste, serving healthier foods and increasing efficiency or cost savings. Barriers revolved around patient preferences, contractual difficulties and costs related to reducing waste. Facilitators included taste testing new recipes that include more sustainable food options and easy access to sustainable products from the prime vendor. Best practices included making familiar dishes plant‐forward and plate waste studies to prevent overproduction.Although there were many barriers to implementation, food service directors had solutions for overcoming challenges and implementing food service sustainability standards, which can be tested in future sustainability initiatives.

Agriculture in Poland plays an important social and environmental role. Accession to the EU resulted in structural and modernization changes, following adjustments to CAP obligations. In 2019, the European Green Deal and "From Farm to Fork" strategies called for circularity, zero emissions, and food and energy security. The purpose of this study was to assess the consumption and energy efficiency of Polish farms, identify challenges in energy management, and formulate recommendations. This study used data from Polish Statistics, FADN, and other public bodies collecting relevant data. The assessment of energy intensity was carried out based on the concept of technical efficiency by Farell and Debreu, defined as the ratio of effects to inputs. In addition, methods of comparative and descriptive statistics were used. The average annual dynamics of energy consumption and CO2 emissions were determined using the compound percentage formula. The results of this research indicate positive changes in the energy management in Polish agriculture, including a decrease in production energy intensity, CO2 emissions, and the amount of waste generated by the investments made. It is necessary to improve farm energy efficiency further and to increase the use of renewable energy to maintain cost competitiveness and meet environmental requirements. [ABSTRACT FROM AUTHOR]

The functions of bright bands in coral and other snakes have long been a puzzle. A common opinion is that coral snakes display aposematic marks and that other red and black banded snakes in the Americas are mimics of coral snakes. In two previous reviews, I challenged this prevailing opinion and showed that red and bands are probably defensive against snake predators. Here, I offer a plausible mechanisms through which red and bands could be protective against ophidian predators: the function of bands is to interfere with the focusing ability of snakes, which eyes, as in fish, rely on a ball lens that moves back and forth, a peculiarity among terrestrial vertebrates. Simulations show how the spherical aberrations created by ball lenses produce local maxima in contrast when out of focus, which would feel in focus. I conjecture that red targets specific visual receptors in snakes active in low light: these receptors would have a slow and saturating response. This conjecture is justified by the lability of vision in snakes and the overabundance of red light in dim light. Those conjectures allow precise and well-respected predictions and credibly explain a wide range of observations, such as the geographical repartition of tricolour snakes, the evolution of triadal patterns, the evolution of specific triadal-like patterns in some Erythrolamprus , and the repeated evolution of black and white banded snakes with a red dorsal line. Fish eyes have similar optics, and the function of the ubiquitous fish bands could likewise be to interfere with the vision of predators. [ABSTRACT FROM AUTHOR]

Porang (Amorphophallus oncophyllus, AO) is a local food source that may be developed to address food security concerns. Diversification in processing should be done to increase its consumption. Amorphophallus oncophyllus macerated with Strobilanthes crispus (AOSC) was added to jelly candy, which was created as a low -calorie food product with useful antihyperglycemic qualities. This study aimed to evaluate the sensory and physical properties of jelly candy, including color and texture. Jelly candy varied in the concentration of AOSC, namely: 0.2, 0.5, 0.7, and 0.9%. The content of macronutrients was analyzed to prove the calorie value of jelly. The sensory evaluation was carried out using a hedonic scale, while color and texture profiles were each analyzed using a chromameter and texture analyzer. Adding AOSC considerably decreased the calorie content of jelly by up to 35%, from 147 Kcal/100 g to between 94.74 and 104.18 Kcal/100 g. In comparison to the control, the addition of AOSC had the same degree of preference in practically every attribute and did not affect total preferences. Additionally, it raised the yellow -blue component (b* value) and the lightness (L* value), but decreased the red -green component (a* value). While the cohesiveness, gumminess, and fracture values of the jelly candy decreased and the hardness values increased, the addition of AOSC did not affect the springiness value. The results of this research will be crucial in the development of new food products, particularly those that are low in calories and appealing to customers due to their improved physical qualities.

Bacteriocins produced by a number of lactic acid bacteria (LAB) comprise a variety of antimicrobial proteins that may be used as antibiotic alternative in food preservation. The present study aimed to isolate and characterize LAB-derived bacteriocin-like substances (BLS) from local fermented foods. A total of twenty-one bacterial strains were isolated and subjected to an antibacterial assay. Five isolates designated as AB1, AB2, AK1, AK2, AnK1 showed inhibitory activity against selected indicator organisms and were subjected to further characterization. Upon BLAST analysis of the 16S rRNA gene sequences, the isolates showed close relationship to Lactobacillus plantarum with similarity ranging from 91 to 97%. Moreover, the antibacterial metabolite production of the isolates was observed to peak on the 5th to 7th day of incubation. Since AnK1 showed the highest zone of inhibition among 5 isolates, it was selected for characterization of the BLS isolated by ammonium sulfate precipitation and anion exchange chromatography. The sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) showed that the AnK1-BLS had a single band and a molecular weight around 15 kDa, and a total protein concentration of 7.06 µg/mL. Interestingly, AnK1-BLS had a broad antimicrobial spectrum on both gram-negative and gram-positive food-borne pathogens, including Escherichia coli, Salmonella enterica, Pseudomonas aeruginosa, and Bacillus subtilis. Moreover, the purified AnK1-BLS exhibited good thermal stability when heated at 80‒121°C. Likewise, its inhibitory activity was not affected by pH in the range of 3.0 to 6.5, with maximum activity recorded at pH 3.0. The results suggest that AnK1-BLS may have application prospects in the food industry. Further studies on the complete protein characterization of AnK1-BLS is recommended to fully harness its capabilities. [ABSTRACT FROM AUTHOR]

The safety and integrity of the global food system is in a constant state of flux with persistent chemical and microbial risks. While chemical risks are being managed systematically, microbial risks pose extra challenges. Antimicrobial resistant microorganism and persistence of related antibiotic resistance genes (ARGs) in the food chain adds an extra dimension to the management of microbial risks. Because the food chain microbiome is a key interface in the global health system, these microbes can affect health in many ways. In this review, we systematically summarize the distribution of ARGs in foods, describe the potential transmission pathway and transfer mechanism of ARGs from farm to fork, and discuss potential food safety problems and challenges. Modulating antimicrobial resistomes in the food chain facilitates a sustainable global food production system. [ABSTRACT FROM AUTHOR]

Heavy metal contamination in leafy vegetables poses significant health risks, highlighting the urgent need for stringent monitoring and intervention measures to ensure food safety and mitigate potential adverse effects on public health. This study investigates the levels of heavy metals, including cadmium (Cd), chromium (Cr), nickel (Ni), lead (Pb), zinc (Zn), and copper (Cu), in locally grown and commercially available leafy vegetables, comparing them to the safety limits established by WHO/FAO. The results revealed that levels of Cd, Cr, Ni, and Pb in the vegetables exceeded WHO/FAO limits, while Zn and Cu remained within permissible bounds. Marketed vegetables exhibited higher metal concentrations than those from nearby farms. For Cu (0.114–0.289 mg/kg) and Zn (0.005–0.574 mg/kg), the daily intake of metals (DIM) was below the dietary intake (DI) and upper limit (UL). Cd's DIM (0.031–0.062 mg/kg) remained below the UL but exceeded the DI. Marketed kale and mint surpassed both DI and UL limits for Ni, while local produce only exceeded the DI. All vegetables had DIM below the DI, except for mint and kale. For Pb, every vegetable exceeded DI limits, with market samples contributing significantly. Cr's DIM ranged from 0.028 to 1.335 mg/kg, for which no set maximum daily intake exists. The health risk index (HRI) values for Zn, Cd, Cu, Ni, and Pb suggested potential health risks associated with leafy greens, while Cr's HRI was below 1. The study underscores the need for stringent monitoring and intervention measures to mitigate the health risks posed by heavy metal contamination in leafy vegetables. These findings suggest that consuming these leafy greens may put consumers at considerable risk for health problems related to Cd, Cu, Ni, Pb, and Zn exposure. [ABSTRACT FROM AUTHOR]

Apple cultivars 'Annurca' and 'Limoncella' are grown locally in the Campania region of Italy and are valued for their distinctive flavour and characteristics, including a high content of nutritionally important bioactive compounds. However, apples are typically stored chilled for several months before consumption, so it is important to assess if the valuable characteristics are still present after postharvest storage. Here, we compare the quality, nutritional parameters, and aroma of these two cultivars with two widely grown international cultivars, 'Golden Delicious' and 'Fuji', after 60 days of storage. The aroma profiles of all four apples were analysed using thermal desorption and gas chromatography–time-of-flight mass spectrometry. We show that the local cultivars are distinct from the international cultivars in their bioactive compound content and their antioxidant activity. 'Limoncella' shows high sugar content, which may be acting as a cryoprotectant during storage, and high total phenolics in the flesh, which is of nutritional interest. We identified 104 volatile organic compounds (VOCs) and showed that the overall aroma profile is distinct for each cultivar, containing 11 published odorant compounds. The 'Annurca' profile is uniquely low in esters. Seven VOCs retain good discrimination across the four cultivars and, together with the quality and nutritional data, separate the two local cultivars from the international cultivars by hierarchical clustering. Overall, the data emphasize the unique characteristics of the two local cultivars and their value. [ABSTRACT FROM AUTHOR]

We use housing transactions to estimate consumer preferences for living near direct-marketed locally produced food, which has implications for both consumer- and producer-centric land use policies. We estimate a pure characteristics sorting model to recover preferences and conduct counterfactual simulations accounting for price feedback effects following resorting after changes to the local food environment. We find that consumers significantly value healthy food access, including different direct sources of locally produced foods. However, the welfare gains and associated price changes arising from policies to increase local food access depend on the targeting method, a key concern for policy makers worried about affordability.

Natal dispersal is a key demographic trait that affects population dynamics, and intraspecific variation in dispersal affects gene flow among populations and source-sink dynamics. However, relatively little is known about the selective pressures and trade-offs that animals face when departing their natal area due to the logistical difficulties associated with monitoring animals during this critical life stage. We used a randomized block design to examine the selective pressure that influence dispersal timing in juvenile burrowing owls (Athene cunicularia) by experimentally altering both food and ectoparasites at 135 nests. We also examined the effects of local food abundance, ectoparasite loads, and parental departure on natal dispersal timing. Juvenile burrowing owls varied widely in natal dispersal timing, and phenotypic plasticity in dispersal timing was evident in juvenile owls' response to our experimental treatments, local conditions, and their parents' departure from the natal area. Moreover, juveniles responded differently than their parents to experimental manipulation of food and ectoparasite loads. Juveniles typically dispersed shortly after their parents departed the natal area, but delayed dispersing more than 2 weeks after parental departure if they did not receive experimental food supplements during a low-food year. In contrast, the experimental food supplements did not affect the migratory departure decisions of adult owls in either year. Juveniles at nests treated for ectoparasites initiated dispersal at a younger age (and prior to adults in the high-food year) compared to juveniles at control nests. In contrast, parents at nests treated for ectoparasites departed later than parents at control nests. Our results suggest that unfavorable conditions (low food or high ectoparasite loads) caused juveniles to delay dispersal, but prompted adults to depart sooner. Our results highlight the extent of intraspecific variation in natal dispersal timing, and demonstrate that ecological conditions affect dispersal decisions of parents and offspring differently, which can create important trade-offs that likely affect life history strategies and responses to climatic changes.

Transitioning toward sustainable food systems and sustainable diets is critical in reducing environmental impact and achieving the Sustainable Development Goals established by the United Nations General Assembly. This transition requires collaborative efforts across multiple stakeholders, including the general public's knowledge and attitudes. To assess the knowledge and attitudes toward food sustainability, we carried out a cross-sectional study among Kuwait University students with a total of 278 participants aged =18 years (78% women and 22% men). A validated questionnaire was used for this study. Most respondents (>70%) recognized the concept of "local food" and "environmental impact." The concept "green water-blue water" was least recognized among respondents (75%). Participants perceived that a sustainable diet was rich in vegetables, included plenty of fresh products, and was affordable. Participants (>66%) perceived a positive impact of meat and its derivatives toward sustainability, a misconception most common among men. Overall, participants with more knowledge about environmental concepts showed favorable attitudes toward a sustainable diet. Women showed more interest in changing their current dietary habits toward food sustainability. In conclusion, despite participants' positive attitude toward food sustainability, lack of understanding persists, necessitating public health interventions aimed at educating consumers about sustainable diets and their impact on the environment.

Introduction: The COVID-19 pandemic caused mainstream food supply chain disruptions, increased food security concerns, and impacted agrifood production and distribution systems. Short food supply chains provided consumers with an alternative method to acquire food outside conventional food supply chains. In this paper, innovation was seen as a solution to external challenges or problems in global food supply chains during a pandemic crisis. The solution was analyzed in the context of the United States and changes in the consumers' behavior and purchasing patterns in the direction of more accepting short supply chains, which led to the successful overcoming of crisis or adaptation of consumers to crisis circumstances. Methods: The Diffusion of Innovations was selected as the theoretical framework. Data were collected from 1,002 American adults from July 13 to August 18, 2021, through an online survey. Results and discussion: Results showed that consumers with higher educational attainment and financial status, from non-rural areas, and with more conservative viewpoints had higher innovation adoption levels, and they were more likely to embrace short food supply chains as an alternative during disruptions to conventional supply chains. Recommendations provide strategies to increase the use of short supply chains during the crisis to better meet the needs of consumers in the food system and improve marketing and communication efforts. Marketing and communication initiatives should engage these food innovators as opinion leaders to increase the adoption of short food supply chains to stabilize food supply in preparation for future crises.

In the dynamic landscape of agriculture and food science, incorporating emergent crops appears as a pioneering solution for diversifying agriculture, unlocking possibilities for sustainable cultivation and nutritional bolstering food security, and creating economic prospects amid evolving environmental and market conditions with positive impacts on human health. This review explores the potential of utilizing emergent crops in Mediterranean environments under current climate scenarios, emphasizing the manifold benefits of agricultural and food system diversification and assessing the impact of environmental factors on their quality and consumer health. Through a deep exploration of the resilience, nutritional value, and health impacts of neglected and underutilized species (NUS) such as quinoa, amaranth, chia, moringa, buckwheat, millet, teff, hemp, or desert truffles, their capacity to thrive in the changing Mediterranean climate is highlighted, offering novel opportunities for agriculture and functional food development. By analysing how promoting agricultural diversification can enhance food system adaptability to evolving environmental conditions, fostering sustainability and resilience, we discuss recent findings that underscore the main benefits and limitations of these crops from agricultural, food science, and health perspectives, all crucial for responsible and sustainable adoption. Thus, by using a sustainable and holistic approach, this revision analyses how the integration of NUS crops into Mediterranean agrifood systems can enhance agriculture resilience and food quality addressing environmental, nutritional, biomedical, economic, and cultural dimensions, thereby mitigating the risks associated with monoculture practices and bolstering local economies and livelihoods under new climate scenarios.

This article applies a governmentality perspective to approach education for sustainability. First, we outline governmentality through a Foucauldian lens and consider the emergence of environmentality in Italian education. Next, we analyse education for sustainability teaching and learning dynamics. Focusing on a pedagogic intervention carried out in a hotel-management vocational high school, we explore how school programming, classroom interactions, teachers, and environmental experts conceptualise food sustainability, influencing the pupils' view. Precisely, by analysing the ‘From farm to fork' programme – the empirical case study we have investigated – three pedagogic processes are detected: ‘framing', ‘politicising', and ‘normalising'. Our argument is that they work in tandem to problematise the socio-ecological implications of eating consumption choices and to guide students towards the neoliberal solution of sustainability. Implications of this research discuss how neoliberalism influences pedagogic activities, especially as it relates to establishing environmentally responsible action and shaping the ethics of the sustainable citizen.

Background.: The purpose of this study was to collect updated school food service purchasing practices from K-12 public school food service directors (SFSD) in Mississippi and to determine their current abilities, experiences, and desires to engage in Farm to School (F2S) activities. Methods.: The online survey was created using questionnaire items from existing F2S surveys. The survey opened in October 2021 and closed in January 2022. Descriptive statistics were used to summarize the data. Results.: Of the 173 SFSD sent email invitations, 122 (71%) completed the survey. The most common fresh fruit and vegetable purchasing practices included Department of Defense Fresh Program (65%) and produce vendor (64%). Forty-three percent of SFSD purchased at least one locally sourced fruit and 40% purchased at least one locally sourced vegetable, while 46% did not purchase any locally sourced foods. The most common challenges for purchasing from farmers included no relationship with farmers (50%) and food safety regulations (39%). Sixty-four percent of SFSD were interested in at least one F2S activity. Conclusions.: Most SFSD do not purchase local foods directly from farmers and almost half do not purchase any local foods regardless of source. Lack of connection with local farmers is a significant challenge to F2S. Recently proposed framework by USDA for shoring up the food supply chain and transforming the food system may help reduce or remove ongoing challenges to F2S participation. [ABSTRACT FROM AUTHOR]

In the one health approach, which summarizes the concept that human, animal, and plant health are interdependent and linked to the ecosystems in which they exist, animal welfare assumes an important role. In addition, the Farm to Fork Strategy of the European Union recognizes animal welfare as an essential component. Transport of animals involves a number of issues related to welfare. Animals are subjected to continuous stress, not only during transit on vehicles, vessels, trains, or airplanes, but also during loading and unloading operations. The handling and transport conditions have improved from basic and relatively rudimentary systems, with elements to attenuate the discomfort of animals having been gradually introduced, especially for long-distance transport. Despite several improvements in animal welfare standards during transportation there are still pressing issues in current EU legislation which deserve reviewing. Recently, several scientific opinions on animal welfare, including during transport, have been published by the European Food Safety Agency, following requests by the European Commission. In addition, the European Court of Auditors published its last report focused on animal welfare during transport. These reports underline the need to review current legislation governing the topic and highlight a number of outstanding issues in the European Union and in Third Countries. This article summarizes the history and current status of this complex issue. [ABSTRACT FROM AUTHOR]

Biclustering, the simultaneous clustering of rows and columns of a data matrix, has proved its effectiveness in bioinformatics due to its capacity to produce local instead of global models, evolving from a key technique used in gene expression data analysis into one of the most used approaches for pattern discovery and identification of biological modules, used in both descriptive and predictive learning tasks. This survey presents a comprehensive overview of biclustering. It proposes an updated taxonomy for its fundamental components (bicluster, biclustering solution, biclustering algorithms, and evaluation measures) and applications. We unify scattered concepts in the literature with new definitions to accommodate the diversity of data types (such as tabular, network, and time series data) and the specificities of biological and biomedical data domains. We further propose a pipeline for biclustering data analysis and discuss practical aspects of incorporating biclustering in real-world applications. We highlight prominent application domains, particularly in bioinformatics, and identify typical biclusters to illustrate the analysis output. Moreover, we discuss important aspects to consider when choosing, applying, and evaluating a biclustering algorithm. We also relate biclustering with other data mining tasks (clustering, pattern mining, classification, triclustering, N-way clustering, and graph mining). Thus, it provides theoretical and practical guidance on biclustering data analysis, demonstrating its potential to uncover actionable insights from complex datasets. [ABSTRACT FROM AUTHOR]

Multiple crises have disrupted food systems around the world. The shocks induced by the COVID-19 pandemic, coupled with increased energy prices and shortages of fertilizers and agricultural inputs, have affected farmers everywhere. By applying inductive, qualitative, and comparative research approaches, we investigate the impact of shocks and crises on diverse food systems. Using mixed qualitative methods, we integrate the voices of (n = 25) farmers belonging to agroecology-based local food systems in Peru, Germany, and the United States with the aims of: (i) understanding the different crisis scenarios; (ii) determining the vulnerabilities induced in farmers; and (iii) identifying the responses and coping mechanisms that farmers deploy in response to shocks. The results illustrate how farmers are affected by the combined effects of labor shortages, rising input costs, high energy prices, and climate change. Farmers' responses to stressors are then analyzed and compared using attributes of food system resilience. Based on our results, we argue that resilience-building is determined not only by the environment in which agroecology is embedded, but also by the responsive capacities of farmers. We emphasize the need for more proactive policies aimed at promoting agroecological and localized production to enhance the resilience of food systems against recurrent shocks and crises.

The continuous Hopfield network (CHN) is a common recurrent neural network. The CHN tool can be used to solve a number of ranking and optimization problems, where the equilibrium states of the ordinary differential equation (ODE) related to the CHN give the solution to any given problem. Because of the non-local characteristic of the "infinite memory" effect, fractional-order (FO) systems have been proved to describe more accurately the behavior of real dynamical systems, compared to the model's ODE. In this paper, a fractional-order variant of a Hopfield neural network is introduced to solve a Quadratic Knap Sac Problem (QKSP), namely the fractional CHN (FRAC-CHN). Firstly, the system is integrated with the quadratic method for fractional-order equations whose trajectories have shown erratic paths and jumps to other basin attractions. To avoid these drawbacks, a new algorithm for obtaining an equilibrium point for a CHN is introduced in this paper, namely the optimal fractional CHN (OPT-FRAC-CHN). This is a variable time-step method that converges to a good local minima in just a few iterations. Compared with the non-variable time-stepping CHN method, the optimal time-stepping CHN method (OPT-CHN) and the FRAC-CHN method, the OPT-FRAC-CHN method, produce the best local minima for random CHN instances and for the optimal feeding problem.

The design of menus is a strategic part of the marketing mix of restaurants and the way they can (or can not) create a competitive advantage and attract the customer's attention. In particular, restaurant menus communicate the restaurant unique selling proposition through its unique understanding of terroir. In this sense, the role of restaurants in the protection of local food identities and the promotion of local food heritage has become a topic of increasing interest. From a qualitative study based on a discourse analysis, the aim of this article is to understand the role of food in dining experiences through the storytelling embedded in the menus of the 8 restaurants awarded with the Michelin Green Star in Catalonia. While results show the pivotal role of products with a local origin, the narrative derived from the menus display meaningful relationships between local and global, old and new culinary techniques. Results also show the preoccupation of restaurants toward the protection of the linkages between the products and the territory, and the promotion of a zero-waste cuisine. Theoretical and practical implications are outlined to create both business and destination marketing strategies based on a "green" storytelling. [ABSTRACT FROM AUTHOR]

United States federal lands are managed for multiple conservation, social, and commercial goals shaped by the visions of diverse interest groups. The rural economic and food-security needs of local public-lands-based communities have important implications for sustainable natural-resource management but can be obscured by national-scale public comment processes. To better understand local concerns and aspirations for management of the nation's largest national forest, the Tongass, we use thematic analysis of public testimonies provided by Southeast Alaska community members as part of the federally mandated Roadless Rulemaking Subsistence Hearings in 2019. The six themes we develop explore speakers' views of an Alaska exemption from the 2001 Roadless Rule, Alaska Native and rural community connections to the forest ecosystem, visions for rural futures, and concerns with the rulemaking process. Explicit consideration of local economic, food sovereignty, and federal rulemaking concerns can inform a broader picture of federal land management. [ABSTRACT FROM AUTHOR]

Background: chronic iron-deficiency anaemia in children has a negative impact on neuronal and cognitive development. Despite current knowledge on this subject, in Bolivia iron intake along the psychomotor development stimulation as part of a comprehensive rehabilitation process for children with severe chronic malnutrition is not yet used. Objective: to evaluate the effect of a neurorestorative diet, consisting of iron supplements and other micronutrients, along with psychomotor stimulation in preschool children with chronic malnutrition, iron-deficiency anaemia and severe psychomotor delay. Patients and methods: twenty-four children between 1 and 56 months of age admitted to the integral nutritional recovery centre (INRC), Paediatric Hospital of Cochabamba, Bolivia were included. A strategy of intervention was applied consisting of nutritional replenishment through the administration of elaborated meals prepared from local foods with high heme and non-heme iron concentration, added with vegetables plus the administration of micronutrient's supplementation and the psychomotor stimulation. Anthropometric indices, psychomotor and biochemical parameters were measured at four times points, during the hospitalisation period. Results: at the beginning, the anthropometric and psychomotor parameters were decreased (between -2 and -3 z score and below 50 % respectively). Combined strategy intervention with iron and other micronutrients together photons produced significant changes between the evaluated time points, both in anthropometric and psychomotor parameters, although these changes were less than expected. Conclusions: the combined strategy used in this study allowed recovery from the anaemia and minimal growth due to the low birth weight or chronic malnutrition. However, the intervention was insufficient to achieve a complete recovery. [ABSTRACT FROM AUTHOR]
