Computer Vision (CV) has proven to be a powerful tool for automation in agri-food industrial processes, offering high-precision solutions tailored to specific working conditions. Recent advancements in Artificial Neural Networks (ANNs) have revolutionized CV applications, enabling systems to autonomously learn and optimize tasks. However, ANN-based approaches often require complex development and lengthy training periods, making their implementation a challenge. In this study, we explore the use of the Segment Anything Model (SAM), a pre-trained neural network developed by META AI in 2023, as an alternative for industrial segmentation tasks in the table olive (Olea europaea L.) processing industry. SAM’s ability to segment objects regardless of scene composition makes it a promising tool to improve the efficiency of olive pitting machines (DRRs). These machines, widely employed in industrial processing, frequently experience mechanical inefficiencies, including the “boat error,” which arises when olives are improperly oriented, leading to defective pitting and pit splinter contamination. Our approach integrates SAM into n CV workflow to diagnose and quantify boat errors without designing or training an additional task-specific ANN. By analyzing the segmented images, we can determine both the percentage of boat errors and the size distribution of olives during transport. The results validate SAM as a feasible option for industrial segmentation, offering a simpler and more accessible solution compared to traditional ANN-based methods. Moreover, our statistical analysis reveals that improper calibration—manifested as size deviations from the nominal value—does not significantly increase boat error rates. This finding supports the adoption of complementary CV technologies to enhance olive pitting efficiency. Future work could investigate real-time integration and the combination of CV with electromechanical correction systems to fully automate and optimize the pitting process. Full article

Greater engagement with alternative food supply chains is considered a key factor in reducing a range of environmental and social harms associated with the global agri-food system. However, consumer engagement with these supply chains is low, and little research has investigated this issue in the Australian context. This study aimed to identify Australian consumers’ drivers and barriers in procuring food grown locally from alternative grocery retailers. Self-reported primary or co-equal grocery shoppers (n = 325) completed measures of drivers and barriers to shopping for locally produced food (within 200 km) from alternative retailers, as well as current behavioural engagement with such. An exploratory factor analysis revealed four key drivers (Food Shopping as an Expression of Values, Food Shopping as a Socio-Emotional Experience, Avoiding “Unnatural” Food, Protesting the Duopoly) and two key barriers (It’s All Too Hard, Local Food Scepticism). Multiple regression analysis demonstrated that together, these drivers and barriers explained a significant 9% of the variance in the frequency of alternate shopping practices, of which only the barrier It’s All Too Hard accounted for a significant amount of unique variance. Findings point to ways to encourage engagement with sustainable food systems, as well as critical barriers to overcoming disengagement. Full article

The pursuit of sustainable protein is underway. This debate is often framed as a choice between two competing agrifood futures: the “no cow” and “clean cow” perspectives. The former comes from alternative protein advocates, while the latter aims to support practices, discourses, and livelihoods associated with regenerative ranching. The findings presented reveal greater nuance than what this simplistic dichotomy suggests. This paper utilizes data collected from fifty-eight individuals in California and Colorado (USA). Participants in the sample were identified by their attendance at various events focused on sustainability in protein production and includes a subsample of regenerative farmers who self-identified as persons of color, disabled or differently abled, and/or part of the LGBTQIA+ (Lesbian, Gay, Bisexual, Transgender, Queer/Questioning, Intersex, Asexual) community. The sample features a range of viewpoints associated with regenerative livestock and non-livestock protein production. The data support arguments aligned with “clean cow” framings, as determined by the anticipated scope of sustainable protein transformations. However, the paper cautions against solely relying on this frame without further interrogating its contours. It particularly notes that the values of specific “clean cow” actors and networks mirror key aspects of “no cow” perspectives. These similarities are especially evident among upstream actors like investors, corporate interests, and government sponsors. For these individuals and networks, the “no” versus “clean” distinction—despite suggesting radically different agrifood futures—overshadows underlying shared concerns that align with core elements of the status quo. A case is also made for greater reflexivity and, thus, inclusivity as we think about who is included in these debates, as the data tell us that this shapes how we frame what is at stake.

This paper reviews, compares, and critically evaluates two broad groups of sustainable agriculture models: “sustainable agriculture” and “sustainable agrifood systems”. The “sustainable agriculture” models—comprising organic farming, regenerative agriculture, climate-smart agriculture, carbon-capture agriculture, and nature-based solutions—focus primarily on improving ecological sustainability through farm-level practices. These models emphasize reducing external, industrial inputs, enhancing biodiversity, and promoting climate resilience, relying on technological and market-based solutions to address environmental concerns. On the other hand, the “sustainable agrifood systems” models—agroecology, alternative food networks, and permaculture—offer more ambitious visions of systemic transformation. These approaches not only seek to implement environmentally sound practices but also aim to reconfigure the broader food system by challenging corporate power, promoting local governance, fostering food sovereignty, and prioritizing social justice. Grounded in grassroots movements, these models emphasize social justice and economic viability in addition to ecological sustainability. This paper’s contribution lies in its comparative analysis of the wide array of sustainable alternatives, highlighting both their strengths and limitations. Adopting an agrarian political economy perspective, it critiques the former camp for limited engagement with structural issues inherent in capitalist agriculture and the latter camp for underplaying the importance of industrial agriculture for national development in the Global South.

The process of standardization within the dominant agrifood system is being accompanied by growing demand for differentiated high-quality food products that are environmentally sustainable. In this scenario, Alternative Food Networks (AFNs) could help the local agrifood sector and local or traditional variety crops regain their pivotal role. The objective of this paper is to assess the potential of AFNs in the metropolitan area of Granada and in the nearby mountain region of the Alpujarra in the promotion and distribution of local varieties of fruit and vegetables from this region. The research took the form of case studies in which the information was collected in semi-structured interviews with the AFNs and then subjected to content analysis. The results highlight that the socioenvironmental commitment of the AFNs is their strongest asset for the conservation, sale, and distribution of biodiverse local variety produce. However, these organizations still have very limited knowledge of local varieties and there are doubts as to their capacity to mobilize sufficient volumes of these products and successfully establish themselves in rural areas.

There is a growing consensus that the modern food system lies at the centre of the great challenges facing humanity and that urgent and profound changes are required in the way that food is produced, processed, distributed and consumed. This review analyses sustainability transitions within agrifood systems, focusing on the role of firms and industries as defined by the Sustainable Transitions Research Network (STRN). This paper conducts the first systematic literature review using bibliometric analysis to assess the current state of research on this theme. The findings reveal a significant increase in publications related to firms and industries associated with agrifood sustainability transitions. Furthermore, the focus of current research is geographically concentrated in the European Union. The review identifies four key themes in the literature, based on the co-occurrence of keywords. These are agriculture, innovation, governance, food systems and agroecology. The review identifies an increasing awareness of the role of farmers in driving sustainability transitions at the farm level. Furthermore, there is an increasing awareness of the interrelated characteristics of the agrifood system, which acknowledges the need for sustainable innovations to occur at multiple stages of the agrifood system. The review also shows that there is growing evidence that innovations can occur through disruptive as well as incremental innovation and highlights the importance of governance influencing transitions. The existing literature raises questions about alternative food networks as sustainable innovations, their potential for significant change in the established food system and the validity of their claims regarding food equity and environmental sustainability. A key theme emerging from the literature is an ecological perspective that identifies the complex biological processes and ecosystems that form an integral part of agricultural production. These findings provide a greater understanding of the current literature landscape of agrifood sustainable transitions relating to firms and industries and lay a foundation for future research.

Global food security is a critical issue today, strained by a wide range of factors including global warming, carbon emissions, sociopolitical and economic challenges, traditional workforce decline and population growth. Technical innovations that address food security, like agricultural robotics, are gaining traction in industry settings, moving from controlled labs and experimental test facilities to real-world environments. Such technologies require sufficient network infrastructure to support in-field operations; thus, there is increased urgency to establish reliable, high-speed wireless communication networking solutions that enable deployment of autonomous agri-robots. The work presented here includes two contributions at the intersection of network infrastructure and in-field agricultural robotics. First, the physical performance of a private 5G-SA system in an agri-robotics application is evaluated and in-field experimental results are presented. These results are compared (using the same experimental setup) against public 4G and private WiFi6 (a newly emerging wireless communication standard). Second, a simulated experiment was performed to assess the “real-time” operational delay in critical tasks that may require quick turnaround between in-field robot and off-board processing. The results demonstrate that public 4G cannot be used in the agricultural domain for applications that require high throughput and reliable communication; that private 5G-SA greatly outperforms public 4G in all performance metrics (as expected); and that private WiFi6, though limited in range, is a fast and very reliable alternative in specific settings. While a single wireless solution does not currently exist for the agricultural domain, multiple technologies can be combined in a hybrid solution that meets the communications requirements.

Agricultural peatlands are the most productive soils in the UK for the cultivation of many food crops. Historical drainage of peat for agriculture (i.e., cropland and managed grassland), without consideration of other associated environmental and climatic impacts, has resulted in a significant emission of greenhouse gases (GHGs). There is a need to reduce GHG emissions without compromising the rural economy and jeopardizing food security in the UK to a greater extent than is currently being experienced. In March 2023, in a bid to identify alternative land management systems for agricultural peatlands to support the UK’s commitment to achieving net zero GHG emissions by 2050, a group of forty investigators met at a workshop convened by the AgriFood4NetZero Network+. The workshop reviewed the state of knowledge surrounding the Fens of Eastern England and their importance for food provision, the economy, cultural identity, and climate change mitigation. A broad consensus emerged for research into how GHG emissions from agricultural peatlands could be reduced, whether alternative farming methods, such as seasonal farming or paludiculture, would offer a solution, and how a localized approach for the Fens could be defined. The development of a holistic, inclusive, and plausible land use scenario that considers all aspects of ecosystem services provided by the Fens is urgently needed. Full article

An agroecological transition can enhance resilience by several means, e.g., managing ecological relationships through agroecosystems, enhancing farmers’ knowledge of natural resources, recycling those resources, maintaining biodiversity, and thus, flexibly adapting to environmental stresses. However, the hegemonic agri-food system has been continuing its capitalist transition, thereby undermining agroecological methods and deterritorialising social bonds. Facing this pervasive threat, an agroecological transition needs a greater convergence between agroecological production and a solidarity economy (economia solidaria or EcoSol in Latin America). Their convergence can be called EcoSol-agroecology, based on short food supply chains (called circuitos cortos there). These efforts develop territorial markets, generate more stable livelihoods, and thus keep producers on the land. In our study, each research team collaborated with an EcoSol-agroecology network to develop Participatory Action Research methods. The COVID-19 pandemic disrupted their circuitos cortos, stimulating creative adaptations or alternatives, alongside demands for policy support measures. These networks have regionally territorialised local initiatives, while also confronting obstacles from the hegemonic system. Although socioecological resilience often means a system’s capacity to bounce back, here it has meant bouncing forwards through new opportunities for solidaristic livelihoods and bonds. EcoSol-agroecology networks, agri-extensionists, and researchers have jointly developed such counter-hegemonic strategies, as illustrated by the case studies here. Full article

Short food supply chains (SFSCs) are advocated as strategies to improve the sustainability of the agro-food system. The recent literature claims that SFSCs are examples of social experimentation and innovation. By scaling up the positive elements of niche alternative food networks, SFSCs can serve as a basis for changing the overall agri-food system. However, their economic impact remains a matter of debate. Local multiplier methods have been used to measure the economic impact of economic sectors at a regional scale. In the case of SFSCs, multiplier methods need to be developed at a local scale and are highly data demanding. This analysis measures the local financial flow created by the MercaTiAmo project by applying the Local Multiplier 3 (LM3) method. MercaTiAmo is organized by a group of citizens and farmers and arranges farmers’ markets three days per week in the city of Parma (northern Italy). To measure the financial flow created by the initiative, data were collected from 10 farmers representing 70% of the farmers participating in the project. The method takes into account the total annual turnover (Round 1), the local expenses of the farmers (Round 2), and the local expenses of the farmers’ suppliers (Round 3). The results suggest that farmers with a higher turnover (Round 1) and percentage of direct expenses in the local area (Round 2) also show higher values of LM3, thus suggesting a higher economic impact, while Round 3 does not affect LM3. The novelty of the study relies on the fact that here the local multiplier method is applied for the first time at the farm level, providing precise information and data on farmers’ upstream supply chain, which can be used to inform policymakers and initiators of SFSCs. Moreover, the study provides a detailed description of the main categories of costs for farmers and which categories of costs are more suited to be locally based. For this reason, the study contributes to the debate on the economic impact of SFSCs in the local area. The method can also be used to provide information to consumers on the economic impact of alternative food networks and local food production. Full article

The main purpose of the article is an attempt to estimate the demand for products traded within short food supply chains in Poland. The survey was conducted in autumn 2021 in the Kamienna Góra county, where the first business incubator in Poland, addressed to farmers and food producers, initiated and supported by the local government, is located. The Computer-Assisted Web Interview (CAWI) method constituted the basis for the process of collecting research material. The channel for reaching respondents was the LIBRUS application and local social media. Responses were mainly given by women, people with incomes in the range of PLN 1000–3000 per person, those aged 30–50, and those with a university education. The research results showed a high level of potential demand for local agri-food products, which should encourage farmers to switch from long to short supply chain models. The persisting low awareness regarding the existence of alternative distribution networks for local products, which primarily requires increased activities in the field of territorial marketing that promote local agri-food products among the residents of municipalities constitutes, from the perspective of consumers, a barrier to the development of short food supply chains.

Conventional agricultural systems have contributed to social, economic and environmental problems and are the main threat to global sustainability. In response, theoretical frameworks to describe the transition to sustainable food systems have been proposed, emphasizing the necessity to shift from farm-level solutions to a focus on interactions within the entire value chain, from production to consumption. Despite the emphasis on the importance and potential of consumers to contribute to sustainable agri-food transitions, approaches to their role have remained within the traditional, linear supply chain framework. Marketing approaches view consumers as passive actors, limited to voting with their wallets, which has deepened the disconnection between consumers, producers and nature, resulting in a triple fracture. We analyze the role of the consumer in agri-food systems, contrasting marketing approaches with other consumers/citizens concepts and locate them within sustainability transition frameworks and a multi-level perspective. We discuss the re-establishment of the connection between farmers and consumers and human–nature connectedness and explore this connection mediated through innovative business models, which act as niche innovations with the capacity to influence regimes and landscapes within the multi-level perspective. The role of consumers/citizens in the co-creation of innovative business models is also addressed. Full article

The interest in short food supply chains (SFSCs) has grown significantly in the last decade, notably in respect of their potential role to achieve more sustainable food chains. However, a major barrier to achieving sustainable supply chains is the uncertainty associated with supply chain activities. Therefore, this paper aims to explore the different resilience capabilities that SFSCs possess and the potential role of digital technologies as enablers of SFSCs’ resilience. Using a case study research approach, semi-structured interviews were conducted in two SFSCs in Mexico. Collected data were analyzed using thematic analysis. Findings suggest that SFSCs possess the supply chain resilience (SC resilience) capabilities investigated here, namely flexibility, redundancy, collaboration, visibility and agility. A key finding is the importance of low-cost digital technologies (including freeware and social media) that can support flexibility, collaboration, visibility and agility. These findings raise important implications for SFSCs actors exploring opportunities to improve their collective resilience. This study expands the current literature by proposing a conceptual framework that summarizes a wide variety of strategies that support SC resilience capabilities in the context of SFSCs.

This study sheds light on a new generation of Swedish food producers, market gardeners, who are attracting attention in terms of food system sustainability, prompted by increasing consumer awareness about the value of healthy and locally produced food. Market gardening is part of a global agroecological movement opposed to industrialized agriculture and its negative impacts on the environment and rural communities. These food producers challenge the incumbent agri-food regime through the building of alternative food networks. This case-based study involving 14 young vegetable producers showed that young people who engage in market gardening are strongly motivated by dual incentives, namely entrepreneurship and transformation to sustainability. Six main competences were identified as important for market gardeners: practical skills related to growing vegetables, business management, innovation and continuous learning, systems thinking, pioneering, and networking. Individuals develop their skills through continuous experiential learning and gain knowledge through peer-to-peer learning using social media. However, they need to acquire certain skills relating to their daily work in the field and to managing a business. Market gardeners currently face a number of barriers erected by the sociopolitical environment, in particular regarding access to research-based knowledge, extension services, and business support.

The negative impacts of the COVID-19 pandemic have further exposed and exacerbated the structural weaknesses and inequalities embedded in the global industrial agri-food system. While the mainstream narrative continues to emphasise the importance of ensuring the uninterrupted functioning of global supply chains to counter COVID-related disruptions, the pandemic has also highlighted the resilience of small-scale, sustainable family farming and of spatially and socially embedded food systems. Based on a quantitative and qualitative analysis of three surveys, this study examines organic and agroecological farmers’ responses to the first COVID-related lockdown (March–May 2020) in Italy, as well as the responses of grassroots alternative food networks (AFN) in the city region of Rome. The results show how local grassroots action played a significant role in ensuring food access, provisioning, and distribution, often in the face of delayed or insufficient action of mainstream food system actors and institutions. These grassroots responses identify opportunities and barriers for agri-food system transformation away from neoliberal, market-based interventions and towards policies that support food sovereignty and democracy in the context of localised, agroecology-based and more resilient agri-food systems.
