In China, the majority of food enterprises are small-sized and medium-sized. While the supervision costs are high, food safety issues are still emerging. Food circulation is an indispensable part in the entire food chain. At present, there are few studies on the regional spread of food safety risks in the circulation field from a macro perspective. This study combines GIS and social network analysis methods to deeply explore the regional circulation characteristics of substandard foods. First, we crawl the dataset of Food Safety Sampling Inspection Result Query System. Then we obtain the geographical locations of the manufacturers and distributors by GIS. Finally, we construct the province-level and city-level substandard foods’ circulation networks, and employ social network analysis to target key cities and paths. The experimental results show that the circulations of substandard foods are characterized by dense province-level network and sparse city-level network, and they are mostly local and short-distance trafficking. 361 cities are divided into 13 city clusters considering the network connection characteristics. Chongqing, Beijing, Zhengzhou, and Changsha are identified as key cities by all measurement indicators, and at least four indicators can identify Shanghai and Wuhan. These cities have the highest priority for combating substandard foods’ circulation networks.

We propose a methodological approach to analyze the content of hyperlink networks which represent networked public spheres on the Internet. Using the case of the food safety movement in the United States, we demonstrate how to generate a hyperlink network with the web crawling tool Issue Crawler and merge it with the results of a probabilistic topic model of the network’s content. Combining hyperlink networks and content analysis allows us to interpret such a network in its entirety and with regard to the mobilizing potentials of specific sub-issues of the movement. We focus on two specific sub-issues in the food safety network, genetically modified food and food control, in order to trace the involved websites and their interlinking structures, respectively.

This article develops the theoretical foundations of supply chain network management in order to investigate the constructs surrounding whole chain success rather than just success at firm level. It is argued that the ‘network success’ link has been under-studied, with most empirical studies focusing on the achievement of goals by an individual firm in a network context. A model of the whole network's success in the context of supply chain networks in food industry supply chain relationships is used. The results identify that network-level goals must be considered alongside firm-level goals in supply chain networks. Furthermore, network-level goals are subject to the impacts of chain management and have to be of particular interest for focal firms that are responsible for the development and implementation of collective strategies.

ObjectiveTo use network science to model complex diet relationships a decade before onset of dementia in a large French cohort, the 3-City Bordeaux study.MethodsWe identified cases of dementia incident to the baseline food frequency questionnaire over 12 years of follow-up. For each case, we randomly selected 2 controls among individuals at risk at the age at case diagnosis and matched for age at diet assessment, sex, education, and season of the survey. We inferred food networks in both cases and controls using mutual information, a measure to detect nonlinear associations, and compared food consumption patterns between groups.ResultsIn the nested case-control study, the mean (SD) duration of follow-up and number of visits were 5.0 (2.5) vs 4.9 (2.6) years and 4.1 (1.0) vs 4.4 (0.9) for cases (n = 209) vs controls (n = 418), respectively. While there were few differences in simple, average food intakes, food networks differed substantially between cases and controls. The network in cases was focused and characterized by charcuterie as the main hub, with connections to foods typical of French southwestern diet and snack foods. In contrast, the network of controls included several disconnected subnetworks reflecting diverse and healthier food choices.ConclusionHow foods are consumed (and not only the quantity consumed) may be important for dementia prevention. Differences in predementia diet networks, suggesting worse eating habits toward charcuterie and snacking, were evident years before diagnosis in this cohort. Network methods, which are designed to model complex systems, may advance our understanding of risk factors for dementia.

The modem network and digitalized society is full of social changes in various accustomed spheres of our lives including transformation in food practices. The author gives an example of the easiest way how to book food virtually and get it home this day according to tastes of a customer. Moreover the article represents new forms of specific societies existed in the Internet called food-blogs. This, on the author's mind, changes the traditional mechanism of people's choice. Food-blogs are analyzed through the prism of multifunctionalism and dynamics of food and trust. When the process of food preparing and eating attains new communicative functions. Moreover the author notes some social reasons why one user choses this or that food-blog. For instance, the popularity of blogger and network users trust, mostly «blinded». Beside the point, the conception of «trust» used in the text is based on science works of contemporary sociologist P. Sztompka. Both socialized and communicative functions of food are described through theories of R. Bart and G. Simmel. It is underlined in the text that food transforms and gains new qualities notin traditional ways we used to think but in social and cultural construction in virtual space and through network communication.

A hypergraph is a generalization of a graph since, in a graph an edge relates only a pair of points, but the edges of a hypergraph known as hyperedges can relate groups of more than two points. The representation of complex systems as graphs is appropriate for the study of certain problems. We give several examples of social, biological, ecological and technological systems where the use of graphs gives very limited information about the structure of the system. We propose to use hypergraphs to represent these systems.

Abstract: This comparative literature review of local food systems, short food supply chains, and civic food networks, subsumed under alternative food networks (AFN), suggests converging them into the novel umbrella-term values-based territorial food networks (VTFN). Based on the analysis of specificities and shortcomings in the four concepts, VTFN aims to enhance conceptual clarity, while the current coexistence conceals structural and systemic commonalities—relevant for understanding pathways to ethical and sustainable food system transformations. Taking stock of issues in the four concepts, VTFN strives to be overarching and pragmatic. It qualifies AFN’s “alternativeness” through social, economic, environmental and governance “sustainability values” and through the co-construction of “territoriality” in varying constellations. Thus, it fosters integrated scientific dialogue about conceptual determinations of emerging networks of food system transitions worldwide.Resumen: Esta revisión bibliográfica comparativa de los sistemas alimentarios locales, las cadenas cortas de suministro de alimentos y las redes alimentarias cívicas, comprendidas en las redes alimentarias alternativas (RAA), sugiere englobarlas en el novedoso término redes alimentarias territoriales basadas en valores (RATV). Basándose en un análisis de especificidades y deficiencias, el RATV aporta claridad conceptual, en contraste con la coexistencia de los conceptos analizados que oculta puntos estructurales y sistémicos en común relevantes para entender las vías para transformar los sistemas alimentarios éticos y sostenibles. Reflexionando sobre los cuatro conceptos, la RATV busca ser global y pragmática. Califica lo “alternativo” de las RAA a través de “valores de sostenibilidad” sociales, económicos, medioambientales y de gobernanza, y de la co-construcción de la “territorialidad” en constelaciones diversas. Por ello, fomenta el diálogo científico integrado sobre las determinaciones conceptuales de las redes emergentes de transiciones de los sistemas alimentarios en todo el mundo.Résumé : Cet article se consacre à une revue de littérature comparative des concepts de Systèmes Alimentaires Locaux (Local Food Systems – LFS), Circuits Courts et de Proximité (Short Food Supply Chains – SFSC), Réseaux Alimentaires Civiques (Civic Food Networks – CFN), rassemblés sous le concept ombrelle de Réseaux Alimentaires Alternatifs (Alternative Food Networks – AFN). Il propose ensuite de les converger en un nouveau concept ombrelle, nommé Réseaux Alimentaires Éthiques et Territoriaux (Values-Based Territorial Food Networks – VTFN). Basé sur l’analyse des spécificités et des faiblesses des quatre concepts courants dans la littérature scientifique, la notion de VTFN apporte une clarté conceptuelle, car la coexistence actuelle de plusieurs concepts masque des points communs structuraux et systémiques – pourtant essentiels pour comprendre les processus de transformations éthiques et durables des systèmes alimentaires. Tout en puisant dans les apports des quatre concepts courants, la notion de VTFN aspire à être englobante et pragmatique. Elle qualifie les aspects “alternatifs” des Réseaux Alimentaires Alternatifs (Alternative Food Networks – AFN) par un cadre de quatre ensembles-clés de “valeurs de durabilité” – que sont l’intégrité environnementale, le bien-être social, la gouvernance éthique et la résilience économique –, ainsi que par une co-construction de “territorialité” en constellations variables. Ainsi, le concept de VTFN favorise un dialogue scientifique intégré sur les déterminations conceptuelles de réseaux émergents de transitions des systèmes alimentaires mondiaux.

In food safety and regulation, there is a need for an automated system to be able to make predictions on which adulterants (unauthorized substances in food) are likely to appear in which food products. For example, we would like to know that it is plausible for Sudan I, an illegal red dye, to adulter "strawberry ice cream", but not "bread". In this work, we show a novel application of deep neural networks in solving this task. We leverage data sources of commercial food products, hierarchical properties of substances, and documented cases of adulterations to characterize ingredients and adulterants. Taking inspiration from natural language processing, we show the use of recurrent neural networks to generate vector representations of ingredients from Wikipedia text and make predictions. Finally, we use these representations to develop a sequential method that has the capability to improve prediction accuracy as new observations are introduced. The results outline a promising direction in the use of machine learning techniques to aid in the detection of adulterants in food.

The relationship between industry and the city is a damaged one. However, with its existing mix of residents, industry and commerce (albeit segregated from one-another) Pretoria West holds the potential for a unique relationship between industry and the citizens of Pretoria. Only by understanding the role that these industries play within the greater context of the city can the rich character and culture of a place be ampli ed and solidi ed in a development plan. Catalyzed by its heritage, development becomes a manifestation of the character of place that will attract further growth and simultaneously embrace the existing stakeholders. e existing industrial built-environment is often misshapen and illegible and whilst it is di cult to organize (and navigate) the seemingly disorganized site, it is possible to resolve; through understanding historic boundaries and development patterns that can be utilized as organizational grids. In this case historic erf divisions and consolidations can be utilized as an organizational tool at a large scale and should serve as a guide to where future structures should be erected in order to maintain a legible built environment. When designing future additions, understanding the historic expansion of these industrial buildings holds the key to a harmonious relationship between old and new. With minimal architectural intent these buildings supply little for the architect to grapple onto, but with material spans and structural repetition forming the underlying ordering principle; it is possible to create a logical and ordered extension of the past.
Die verhouding tussen industrie en die stad is beskadig en as gevolg word industrië stelselmatig verwyder van die stad. Die mengsel tussen inwoners, industrie en handel in Pretoria Wes (albeit geissoleer van mekaar) gun egter die potensiaal tot ‘n unieke verbandskap tussen industrie en die inwoners van Pretoria. Slegs deur die rol te erken wat die industrië speel ten opsigte van die stad se groter konteks, kan die karakter en kultuur van so ‘n omgewing versterk en vasgevang word in ‘n ontwikkelings plan. Erfenis dien as katalisator vir ontwikkeling van die karakter van plek wat in beurt verdere nansiële groei sal aanhits. Die bestaande industriële bou-omgewing is misvorm en onvoorspelbaar. Alhoewel so ‘n omgewing nie aan die individie toeleen om weg te vind of organiseer nie, is dit moontlik deur die ontginning van historiese grense en ontwikkelings patrone wat kan dien as organiseerings mates. Historiese erf indelings en konsolodasies kan gebruik word om te dien as ‘n gids vir toekomstige toevoegings, om sodoende die nuwe argitektuur uit die bestaande te laat vloei. Die resultaat is ‘n leesbare en geordende bou-omgewing. Die ontwerp van die nuwe verbeelding steun op die morfologie van die bestaande omgewing om ‘n harmoniese verhouding tussen oud en nuut te skep. Materiale se span afstande neem die rol van die onderliggende orde stelsels aan as gevolg van die gebrek aan aansienlike argitektoniese bedoelings in die bestaande omgewing. Sodoende is ‘n leesbare en logiese uitbreiding van die verlede en na die toekoms moontlik in ‘n omgewing wat ontstaan het sonder ontwerp vir ervaring van mense.

Local food networks (LFNs) have engendered a great deal of debate in the food justice community; scholars and activists are dubious about the potential of LFNs to contribute to the subversion of the very hierarchies of privilege that created the need for the food justice movement. Using a case study of the Claremont, California area local food network, I operationalize a definition of LFNs, defining them by the people, activities, and exchanges involved in the local food network. I provide a grounded view of these three facets of the Claremont area local food network to analyze the extent to which the network both perpetuates and subverts hierarchies of privilege. About 40 ethnographic interviews with key players in the Claremont area local food network show that the network is a patchwork of identities, values, goals, methods, interactions, and outcomes. The subversion and perpetuation of hierarchies of privilege occur simultaneously in nearly every part of the local food network, and the network has potential to enhance the subversive aspects to work towards a larger political challenge.

Food systems are vulnerable to the impacts of resource scarcity, climate change, and population growth, as well as the issues associated with unsustainable social, environmental and economic practices. These challenges have encouraged local food systems as an alternative to global supply chains. This thesis studies this trend at the urban level in order to explore issues and opportunities for change. It argues that urban food systems need to embrace both sustainability and resilience. A sustainable urban food system has an economy that serves social needs while safely operating within ecological limits. Resilience, on the other hand, includes the ability to recover from shocks such as extreme weather events, as well as the capacity to adapt and ultimately transform in response to the ongoing impacts of climate change. The main research question that this thesis investigates is “How can alternative food networks help to foster sustainable and resilient urban food systems considering climate change and increased urbanisation?” A comparative case study approach was used involving local initiatives in the Brisbane and greater Melbourne metropolitan regions (Australia). Both Australian urban areas have similar economic development; however, differences can be found in terms of institutional interest and the existence of food policies. The gathering of a diverse picture of alternative food networks was the strategy adopted for selecting the initiatives that participated in this research. The criteria that alternative food networks should attend were the existence of goals related to access to healthy food, fairer conditions for food workers, and reduction of environmental impacts. The thesis used multiple sources of data including primary (semi-structured interviews with founders or members of initiatives and field observation) and secondary data (publicly available documents such as annual reports). The findings of this research contribute to the conceptualisation and planning of sustainable and resilient urban food systems, as well as, to the knowledge on the role and limitations of alternative food networks in achieving this. The case study conducted in this thesis revealed how alternative food networks can contribute to the creation of food provision systems that are aligned with environmental sustainability and social justice. The thesis exposed the particularities of initiatives that, among other aspects, have minimal food loss and waste, supports agroecology, provides farmers with fair payment and makes organic food affordable. Alternative food networks demonstrated to have resilience building capacity, something that is not confined to its borders and can impact on the whole urban food system. Alternative food networks’ values travel and allow the replication and creation of new models, however, not in the pace necessary for a wider urban food system transformation. The main challenge exposed by this thesis for alternative food networks is the need for scaling up by influencing institutions and policies more broadly.

Portland, OR, is the site of a unique urban food cart phenomenon that provides opportunities for small business ownership and access points for culturally specific food for the city's foreign-born and minority populations. Known as a "foodie haven," Portland also has an active sustainable food movement with engaged citizens and support from city and regional policies aimed at significantly increasing the consumption of local food. To date, there have been no in-depth studies on the sourcing habits of Portland food cart owners and whether or not these street-level actors are involved in the area's local alternative food movements (AFNs). The current understanding of the Portland food cart phenomenon is based on studies that have focused on carts and pods located in the central business district and "inner-ring" areas of the city. Areas beyond these locations (defined as Eastern Portland) are currently home to the majority of the city's growing foreign-born and minority populations. This thesis uses a situational analysis framework to explore the food supply practices of ethnic food cart owners operating in Eastern Portland cart pods. I investigate the feasibility of purchasing locally grown ingredients for use in ethnic cuisines and the degree to which cart owners incorporate the region's prevailing locavore ethics into their everyday culinary practices. Findings from this inquiry suggest that ethnic cart owners in Eastern Portland have a range of habitus, or personal dispositions and embodied knowledge, that is reflected in how they perceive the benefits of and barriers to "buying local" and the extent (if any) that they engage with AFNs in the Portland area. I assert that ethnic food cart owners in Eastern Portland are performing multiple community roles by providing access points for culturally specific cuisines for their particular ethnic groups, while also offering exotic experiences to other residents and tourists alike. I discuss variations within the food cart phenomenon itself by highlighting the differences in design, amenities, types of access, and neighborhood customer bases of cart pods located in Eastern Portland. Finally, I discuss future research directions for understanding the dynamics of food supply chains in small-scale, direct-to-vendor relationships and the implications for local and regional food sustainability policy goals.

This thesis considers the problem of how to design an industrial network to reduce cost, increase efficiency, and reduce environmental burdens. A recent approach is further developed that uses analogies with biological food webs to guide industry design. Studying ecological food webs shows that among the metrics in use, critical quantities of interest for industry design include the internal cycling of energy, the ratio of producers to consumers, and the ratio of efficiency to redundancy in the network. Metrics that are calculated using flow based information are also introduced for use in industry, a significant step forward for bio-inspired network design. A comprehensive data set of proposed, operational, and failed eco-industrial parks is compiled for use with structural food web analyses. A data set of biological food webs is also assembled to calculate sustainable benchmark values used as goals for the industrial designs. This research an essential difficulty in bio-inspired design approaches by quantitatively analyzing components of food web design by reconstructing found relationships from science and engineering 1st principles, specifically using thermodynamic 1st law efficiency. Results from this work have the potential to provide industry-wide cost savings, increase efficiency, and reduce environmental burdens through a reduction in raw material consumption and waste disposal. The results also support the view that financial competitiveness and sustainability need not be mutually exclusive: using food web network patterns embodying both economically and environmentally desirable properties, biologically redesigned industrial networks can ease both environmental and economic burdens.

The goal of this research was to better understand how farm families adapt to global environmental and political-economic change to secure their livelihoods and to build more resilient food systems. The dissertation reports on five iterative cycles of participatory action research that resulted in a diversity of pragmatic, conceptual and theoretical outcomes. I first examined how farmers adapted to the BSE (bovine spongiform encephalopathy) crisis in the Canadian Prairies, identifying three general adaptation types: ‘exiting’ from beef production or agriculture; ‘enduring’ through adaptations that seek stability; and ‘innovating’ to pursue new opportunities, including direct farm marketing and cooperatives as important forms of grassroots adaptation. Next, I reported on a five-year action research project that developed a “civic food network” in rural Manitoba, which emerged in large part as a response to the BSE crisis. This case study examined the tensions, politics and opportunities that arise through the intensely socially embedded relationships that underpin these grassroots innovations. I argue that CFNs must productively engage with difference if they are to reach their full potential for rural development and social change. Next, I examine the barriers that confront the local food movement, especially as they relate to food safety regulations. A series of short articles and videos are presented that were used to buttress the political efforts of our participatory action research team to advocate for scale-appropriate regulations in Manitoba. Next, I examined my PhD research as a whole to illustrate how participatory action research transgresses “academic” and “non-academic” knowledge and space to mobilize knowledge in intentional processes of social transformation. Through this research, we developed three Knowledge Mobilization strategies. These include: Using transmedia to exchange knowledge via multiple platforms and mediums; “setting hooks” to draw together diverse knowledge communities; and layering to deliver knowledge at varying levels of detail and complexity. Finally, through a performative autoethnographic script, I deconstruct graduate education, the dissertation and the professionalizing discourses that impede a vibrant “public scholarship” in Universities. As a whole, this participatory action research simultaneously argues for and also embodies democratic approaches to research and to agriculture and food practice and policy.

The Swedish alternative food networks landscape is underdeveloped compared to that of the US or the countries of Western Europe, however its development has sped up in recent years. The relationship between the farmer and the food hub is the first one to be built when an Alternative Food Network is being set up and therefore represents a valid starting point in the hitherto scarcely studied field of alternative food distribution in Sweden. The paper used a relationship-marketing framework with the addition of elements from Civic Food Networks conceptualization of Alternative Food Networks in order to explain the creation and maintenance, as a well as the quality and depth of supplier-distributor relationships in two cases of Swedish food hubs. Given the immaturity of the Swedish market, this paper tried to explore the possible variations existing in the landscape. In the case of student-led food cooperative Ultimat and its two studied suppliers, values and larger local food systems goals played the primary role in creating and maintaining the relationship, in spite of the poor economic performance of such a relationship in the eyes of the suppliers. The linkages forged between the two entities are strong due to shared values and common goals. In the case of Bygdens Saluhall, the values play a certain role, but the economic element remains crucial for the farmers. At the same time, the connection is closer and ownership of the project by the farmers more significant. Additionally, points of interest arose for future research, notably the diverging stance of Ultimat’s suppliers vs. Bygdens Saluhall’s suppliers in the question of pro-business food hubs and organization of alternative food networks in general.

The food provision system of today has been argued to be unsustainable with large scale production, price-pressure and outbreaks of diseases. Many consumers in the EU and Sweden are reacting to these issues and are becoming increasingly interested in finding local food alternatives that they consider to be safer and of higher quality. However, the small local food producers due to scarce budgets and marketing skills have problems in reaching this target market. Partly due to this, there has been an emergence of Alternative Food Networks (AFN) within which producers come together to get assistance in marketing and sales. Social media has emerged as a phenomenon that is argued by marketing scholars to be a highly useful tool to spread information in a cost-efficient way. Therefore, this study seek to answer the explorative question: “How do Alternative Food Networks use social media in order to help small local food producers reach the market?” The main purpose of the thesis is to explore and develop an understanding of how the emerging AFNs use social media to promote small local agricultural producers and help them in reaching the market. This will be done by investigating AFNs as Small-Medium Enterprise (SME) marketing networks, and how these operate in terms of the theoretical areas external marketing communication, coordination of the SME marketing network, segmentation practices and sales promotion. The theoretical contribution is to see how AFNs work in terms of these areas, and the practical implications will be to give advice on how AFNs should use social media to improve these areas. The study is done in an exploratory manner, and the data collection has been performed in accordance with qualitative research. This has been done through seven semi-structured interviews with respondents from six different AFNs in Sweden that are active on social media. The conclusions of this study shows that AFNs value the use of social media, however they utilize this tool to a varied degree. The AFNs use it to inform and to interact with their customers. Social media does not seem to be very actively incorporated into network communication or monitoring. The AFNs have many ideas about who their customer groups are, and in some cases these have been identified specifically on social media, which has been used to some extent for targeted advertising. The AFNs position themselves as a “good” food alternative. In sales promotion the AFNs mainly promote their events on social media, and have also promoted discounts to some extent. The study provides new theoretical knowledge in the area of marketing through social media by SMEs like AFNs. Practical implications for the AFNs are discussed, which mainly involve increasing the time spent on social media as a mainly free and powerful marketing tool.

Food allergy is a rising, global epidemic. Some Malaysian cooking contains food-allergic-reaction-causing ingredients that may cause severe allergic reactions. A food allergen detection system in Malaysian food is proposed for tourists with food allergies who are unfamiliar with the wide variety of Malaysian dishes to prevent severe allergic reactions. This work focuses on three major food allergens, which include peanuts, cow’s milk, and shellfish. A new Malaysian food image dataset was prepared, and transfer learning on the custom dataset was done via fine-tuning and feature extraction techniques. Comparisons on the ResNet50, InceptionV3, and VGG16 architectures are done based on the accuracy of each model on the testing data. The VGG16 architecture is concluded as the most suitable neural network model for food allergen detection in Malaysian food. The proposed classifier achieved an accuracy of 80.56% on the test samples. The final model is loaded into a Graphical User Interface (GUI) application to demonstrate the results of the Malaysian food classification model.

Gelation is one of the most important functional properties of proteins as it provides texture and structure in foods. Gelatin, egg white and whey proteins are widely used as gelling agents in the food industry. Plant proteins are considered inferior to animal proteins in gelling properties. With the recent surge in demand led by sustainability and health considerations, plant-based food products have taken a center stage in food product innovation. This trend has spurred academic and industrial interest to explore the opportunity of developing gelling ingredients from diversified plant protein sources, replacing animal protein based gels. This presentation will introduce the recent research efforts in our group to develop gelling properties from emerging sources of plant proteins (e.g. pea, lentil and oat). The structural design approaches (e.g. pH-shifting, protein aggregates to build gel network) and novel technologies (e.g. cold plasma, high pressure) that have potential to increase gel performances from plant proteins will be highlighted. The gel rheological properties and mechanical strength as impacted by the protein composition, conformation and aggregation will be discussed. The food application of plant protein based gels will be illustrated.

This study leveraged existing data infrastructure and relationships from the Feed the Future Senegal Naatal Mbay (“flourishing agriculture”) project, funded by the US Agency for International Development (USAID) and implemented by RTI International from 2015 to 2019. The research informed and empowered farmer organizations to track and respond to rural households in 2020 as they faced the COVID-19 pandemic. Farmer organizations, with support from RTI and local ICT firm STATINFO, administered a survey to a sample of 800 agricultural households that are members of four former Naatal Mbay–supported farmer organizations in two rounds in August and October 2020. Focus group discussions were conducted with network leadership pre- and post–data collection to contextualize the experience of the COVID-19 shock and to validate findings. The results showed that farmers were already reacting to the effects of low rainfall during the 2019 growing season and that COVID-19 compounded the shock through disrupted communications and interregional travel bans, creating food shortages and pressure to divert seed stocks for food. Food insecurity effects, measured through the Household Food Insecurity Access Scale and cereals stocks, were found to be greater for households in the Casamance region than in the Kaolack and Kaffrine regions. The findings also indicate that farmer networks deployed a coordinated response comprising food aid and access to personal protective equipment, distribution of short-cycle legumes and grains (e.g., cowpea, maize) and vegetable seeds, protection measures for cereals seeds, and financial innovations with banks. However, food stocks were expected to recover as harvesting began in October 2020, and the networks were planning to accelerate seed multiplication, diversify crops beyond cereals, improve communication across the network. and mainstream access to financial instruments in the 2021 growing season. The research indicated that the previous USAID-funded project had likely contributed to the networks’ COVID-19 resilience capacities by building social capital and fostering the new use of tools and technologies over the years it operated.

This paper explores how food inequities manifest at a territorial level, and how food territories are experienced, understood, and navigated by stakeholders to address those inequities. We interpret ‘food territory’ as a relational and transcalar concept, connected through geography, culture, history, and governance. We develop our exploration through four empirical cases: (i) the Cerrado, a disputed Brazilian territory that has been framed and reframed as a place for industrial production of global commodities, to the detriment of local communities and nature; (ii) urban agroecology networks seeking space and recognition to enable food production in the city of Rio de Janeiro, Brazil; (iii) informal food networks forming a complex web of intersecting local and global supply chains in Worcester, a secondary South African city; and (iv) periodic food markets in Ghana that synchronise trade systems across space and time to provide limited profit-making opportunities, but nonetheless accessible livelihood options, for poorer people. Examining these four cases, we identify commonalities and differences between them, in terms of the nature of their inequities and how different territories are connected on wider scales. We discuss how territories are perceived and experienced differently by different people and groups. We argue that a territorial perspective offers more than a useful lens to map how food inequities are experienced and interconnected; it also offers a tool for action.

Food hypersensitivities (FH) include food allergy, food intolerance and coeliac disease. Food allergy and coeliac disease involve an immune mediated reaction to certain foods; food intolerance is caused by a non-immune mediated reaction (such as an enzymatic or pharmacological effect). Each of these FHs result in unpleasant symptoms if the food is eaten in sufficient quantity, with food allergic reactions sometimes resulting in life-threatening symptoms. Management of FH by an individual or members of their family therefore involves constant vigilance and risk assessment to determine if a food is safe to eat. Research over the last twenty years has demonstrated that this burden, along with the unpredictable nature of FH reactions, has an impact on quality of life (QoL). QoL encompasses our emotions, physical health, the environment we live in, our social networks and day-to-day activities. FH has been shown to have an impact on many of these areas, however there are still research gaps. In particular, many studies focus on children, adolescents or parents rather than the adult population and little is known about those with food intolerances. In order to make a comprehensive characterisation and evaluation of the burden caused by living with FH, the day-to-day management of FH and associated inconveniences, the FSA has commissioned this project, led by Aston University. The project is called the FoodSensitive study and this report relates to findings for workstream one, a survey to assess the impact of FH on QoL. This survey was carried out in two waves, one year apart. This report covers the second wave and a comparison of wave one and two for those participants who completed both waves.

The food services sector has been evolving rapidly over the past decade, accelerated by the Covid-19 pandemic. The traditional linear model of food producers selling through wholesalers to brick and mortar retailers, restaurants and hospitality venues is increasingly being displaced by complex interactive digital ecosystems of online food services providers. Consumers are increasingly able to access food directly at various stages along the traditional value chain via interaction with digital platforms and rapid home-delivery networks, realising greater convenience, more variety in food products and services from a dynamic start-up scene, and overall enhanced value. FSA needs to stay abreast of these changes and develop regulatory responses to ensure these innovations are aligned with the public good and do not compromise food safety and public health.

Growing global water stress caused by the combined effects of growing populations, increasing economic development, and climate change elevates the importance of managing and allocating water resources in ways that are economically efficient and that account for interdependencies between food production, energy generation, and water networks—often referred to as the “food-energy-water (FEW) nexus.” To support these objectives, this report outlines a replicable hydro-economic methodology for assessing the value of water resources in alternative uses across the FEW nexus–including for agriculture, energy production, and human consumption—and maximizing the benefits of these resources through optimization analysis. The report’s goal is to define the core elements of an integrated systems-based modeling approach that is generalizable, flexible, and geographically portable for a range of FEW nexus applications. The report includes a detailed conceptual framework for assessing the economic value of water across the FEW nexus and a modeling framework that explicitly represents the connections and feedbacks between hydrologic systems (e.g., river and stream networks) and economic systems (e.g., food and energy production). The modeling components are described with examples from existing studies and applications. The report concludes with a discussion of current limitations and potential extensions of the hydro-economic methodology.

Original objectives: The long-term goal of the proposed research is to elucidate the transcription factors, genes and metabolic networks involved in carbon metabolism and partitioning in response to water deficit. The proposed research focuses on the GTLcalcium/calmodulinbindingTFs and the gene and metabolic networks modulated by these TFs in Arabidopsis thaliana. The specific objectives are as follows. Objective-1 (USA): Physiological analyses of GTL1 loss- and gain-of-function plants under water sufficient and drought stress conditions Objective 2 (USA / Israel-TAU): Characterizion of GTL target genes and bioinformatic analysis of data to eulcidate gene-network topology. Objective-3 (Israel-TAU): Regulation of GTLmediated transcription by Ca²⁺/calmodulin: mechanism and biological significance. Objective-4 (Israel-BGU): Metabolic networks and carbon partitioning in response to drought. Additional direction: In the course of the project we added another direction, which was reported in the 2nd annual report, to elucidate genes controlling drought avoidance. The TAU team has isolated a few unhydrotropic (hyd) mutants and are in the process of mapping these mutations (of hyd13 and hyd15; see last year's report for a description of these mutants under salt stress) in the Arabidopsis genome by map-based cloning and deep sequencing. For this purpose, each hyd mutant was crossed with a wild type plant of the Landsberg ecotype, and at the F2 stage, 500-700 seedlings showing the unhydrotropic phenotype were collected separately and pooled DNA samples were subkected to the Illumina deep sequencing technology. Bioinformatics were used to identify the exact genomic positions of the mutations (based on a comparison of the genomic sequences of the two Arabidopsis thaliana ecotypes (Columbia and Landsberg). Background: To feed the 9 billion people or more, expected to live on Earth by the mid 21st century, the production of high-quality food must increase substantially. Based on a 2009 Declaration of the World Summit on Food Security, a target of 70% more global food production by the year 2050 was marked, an unprecedented food-production growth rate. Importantly, due to the larger areas of low-yielding land globally, low-yielding environments offer the greatest opportunity for substantial increases in global food production. Nowadays, 70% of the global available water is used by agriculture, and 40% of the world food is produced from irrigated soils. Therefore, much needs to be done towards improving the efficiency of water use by plants, accompanied by increased crop yield production under water-limiting conditions. Major conclusions, solutions and achievements: We established that AtGTL1 (Arabidopsis thaliana GT-2 LIKE1) is a focal determinant in water deficit (drought) signaling and tolerance, and water use efficiency (WUE). The GTL1 transcription factor is an upstream regulator of stomatal development as a transrepressor of AtSDD1, which encodes a subtilisin protease that activates a MAP kinase pathway that negatively regulates stomatal lineage and density. GTL1 binds to the core GT3 cis-element in the SDD1 promoter and transrepresses its expression under water-sufficient conditions. GTL1 loss-of-function mutants have reduced stomatal number and transpiration, and enhanced drought tolerance and WUE. In this case, higher WUE under water sufficient conditions occurs without reduction in absolute biomass accumulation or carbon assimilation, indicating that gtl1-mediated effects on stomatal conductance and transpiration do not substantially affect CO₂ uptake. These results are proof-of-concept that fine-tuned regulation of stomatal density can result in drought tolerance and higher WUE with maintenance of yield stability. Implications: Accomplishments during the IS-4243-09R project provide unique tools for continued discovery research to enhance plant drought tolerance and WUE.
