Abstract
The COVID-19 crisis exposed significant vulnerabilities within the intricate structure of global food supply chains (GFSCs), severely interrupting the smooth movement of food from producers to consumers. This global health emergency underscored the urgency for food-related enterprises to revise their strategies in anticipation of the post-pandemic landscape. This paper explores the implications of COVID-19 on food security and GFSCs, focusing on two North American nations—Canada and the United States—and proposes a strategic model for constructing smarter and more resilient supply chains in a post-COVID-19 context.This study adopts a general review approach, investigating how the COVID-19 pandemic influenced food security and disrupted global food systems. A thorough literature review was conducted to understand the scope of the issue, highlight gaps in existing research, and develop pertinent research questions. Empirical data from Statistics Canada and recent studies on food insecurity in the United States were examined. Insights from these analyses were synthesized into a proposed framework. The analysis confirms that COVID-19 significantly disrupted GFSCs, contributing to heightened food insecurity in Canada and the U.S. Specific disruptions included labor shortages on farms, transportation restrictions, altered consumer demand, production shutdowns, reduced access to food, trade limitations, and delays in distribution.

1. Introduction
As the SARS-CoV-2 virus rapidly propagated across continents, the World Health Organization (WHO) officially classified the outbreak as a global pandemic on March 11, 2020 [2]. In response, numerous nations announced public health emergencies and were encouraged by the WHO to implement policies aligned with the Global Strategic Preparedness and Response Plan [1][5]. Consequently, a range of containment protocols—including full lockdowns, emergency declarations, border shutdowns, curfews, and restrictions on travel and commerce—were swiftly enacted to curb viral transmission [4]. These measures, although implemented differently across nations, contributed significantly to limiting the spread of COVID-19 [6]. However, they also disrupted the flow of goods and services globally, including the vital operations of the global food supply chain (GFSC) [7].
Despite the presence of sufficient food stocks at the onset of the crisis, mass panic led to over-purchasing and hoarding behavior, triggering temporary shortages and disorganized distribution in several countries during initial lockdown phases [10] [13]. Reports indicated that the pandemic did not immediately reduce primary food production or demand but rather destabilized the intricate systems connecting agricultural producers to final consumers [11]. According to a recent OECD analysis, the primary challenge emerged not from production shortfalls but from the upheaval of the supply network that links farms to dining tables and the abrupt shift in consumption patterns [12].
The economic fallout and logistical breakdowns caused by the pandemic have placed immense pressure on food security worldwide [8] [15]. As identified in recent research, one of the most detrimental effects of COVID-19 on global food access was the decline in household income, which critically endangered people’s ability to purchase sufficient and nutritious food [9].
As of now, there is no definitive global schedule for the relaxation of pandemic-related restrictions. Nonetheless, in preparing for the post-COVID-19 era, food industry stakeholders who have adapted through technological innovation, supply diversification, inter-organizational cooperation, and sustainability integration are expected to emerge more resilient and competitive [14] [18]. COVID-19 has had far-reaching effects across all four dimensions of food security as defined by the Food and Agriculture Organization (FAO): availability, access, utilization, and stability [3] [17].
In this regard, the Fourth Industrial Revolution—or “Industry 4.0″—offers opportunities to strengthen food systems through digital technologies, automation, decentralization, and e-commerce integration into GFSCs [19] [21]. Yet, the pandemic has exposed structural weaknesses in GFSCs built around lean production and just-in-time logistics models [16]. This vulnerability significantly hindered the seamless flow of agricultural goods from origin to consumer, particularly in nations like the United States and Canada [20] [23].
The global crisis has served as a wake-up call for companies operating in food sectors to reconfigure their supply networks with adaptability, innovation, and preparedness in mind. A future-proof GFSC will rely on smart technologies and flexible designs that can withstand similar global disruptions [22]. Notably, there appears to be a gap in current literature examining the dual impact of COVID-19 on food security and food supply chain logistics in the specific context of Canada and the U.S., which this paper aims to address.
To achieve this, the study is driven by two core research questions:
RQ1. How has the COVID-19 pandemic influenced food security and disrupted global food supply systems?
RQ2. What strategies can stakeholders adopt to transform global food supply chains into more resilient and intelligent systems during and beyond the COVID-19 era?
Accordingly, this research investigates the primary effects of the pandemic on critical food supply operations and food access challenges. Using Canada and the United States as case examples, this study assesses the extent of food insecurity and presents a proposed strategic framework for enhancing GFSC resilience and intelligence in a post-pandemic world.
2.1 Effects of COVID-19 on the International Food Supply Chain
A global food supply chain (GFSC) encompasses the interconnected activities, data flows, and logistical pathways that facilitate the production and delivery of food across borders. These systems link farms, processing centers, and distribution hubs that are often located in various parts of the world [12]. The outbreak of COVID-19 severely disrupted these transnational networks, creating cascading failures from agricultural production to retail distribution [7].
Ensuring food security remains a critical goal for global supply systems. During the pandemic, operational disturbances in GFSCs heightened risks across the food industry, threatening continuity and service delivery [5]. It has been emphasized that swift evaluations can help identify short-, medium-, and long-term measures to improve adaptability and manage both global and regional shocks more effectively [19]. According to sectoral segmentation, GFSCs typically involve five functional stages: agricultural cultivation, post-harvest handling, processing, distribution/retail, and final consumption [9]. These stages are often illustrated in structured models that show systemic dependencies and vulnerabilities.
Public anxiety surrounding food availability intensified as COVID-19 progressed, fueled by instability in the food system and threats to affordability and accessibility [26]. The pandemic has impacted the food system in two major dimensions—supply capacity and consumer demand [16][24]. While agricultural prices declined in some instances, multiple disruptions persisted across the supply chain. These included: limits on food transportation, reduced access to markets, delayed deliveries, altered consumption patterns, labor shortages, closed production plants, restrictive trade regulations, and uncertainty in meeting health and safety standards, especially with imports from heavily affected regions [21] [34] [41].
|
Numerous countries responded by enacting national guidelines aimed at minimizing disruptions to food systems during the crisis. Still, significant issues remain unresolved, ranging from supply volatility to safety compliance [28]. Safety protocols for workers, such as health screenings, enhanced cleaning routines, facility disinfection, and real-time monitoring, were introduced to reduce virus transmission in food-related environments [22]. Yet, challenges in managing production, supply, and distribution remain widespread [11].
The following are five core areas where the pandemic has disrupted GFSCs:
(1) Agricultural Output: Food production activities have been severely impacted as a result of restricted border mobility and labor shortages. Large quantities of perishable crops were left unharvested as seasonal and migrant workers either could not travel or avoided risk of infection [38].
(2) Transportation and Logistics: The movement of agricultural goods was heavily constrained by border closures, reduced air freight options, and restrictions on logistics services. These limitations intensified delivery delays, raised transportation costs, and worsened supply gaps—thereby exacerbating food insecurity in both developed and developing economies [13] [36].
(3) Food Processing: Many processing operations either slowed output or temporarily ceased operations due to pandemic-related containment rules and labor scarcities. In Canada, for instance, poultry output was intentionally reduced by over 12% as a precautionary response to market instability [25].
(4) Market Channels: The term “go-to-market” encompasses a firm’s entire approach to customer engagement, encompassing logistics, sales, and distribution frameworks. Businesses that relied on institutional or out-of-home food consumption—such as restaurants and catering—saw major reductions in demand, impacting revenue and resource allocation [27].
(5) Raw Material Sourcing: Retailers and grocery suppliers struggled to maintain inventory levels due to disruptions in sourcing ingredients. Complex food items with multiple inputs became increasingly difficult to produce and, in many cases, disappeared from store shelves entirely [18] [31].
The COVID-19 pandemic has therefore exposed the systemic fragilities and lack of resilience embedded in global food networks. These findings highlight an urgent need to develop more flexible, responsive, and technology-integrated supply chains capable of withstanding similar global-scale crises.
2.2 Overview of Food Security
Food security plays a fundamental role in achieving the global objectives outlined in the 2030 Sustainable Development Goals (SDGs), particularly those focused on eradicating hunger and preserving the planet’s ecosystems [8]. It is commonly defined as the consistent provision of adequate, safe, and nutritious food to a population, allowing individuals to meet dietary requirements and maintain a healthy and active lifestyle [15] [32]. The concept includes ensuring uninterrupted access to food resources during normal conditions as well as during emergencies like natural disasters, climate events, or global pandemics [11].
The Food and Agriculture Organization describes food security as a condition where all individuals, at any given time, have physical, economic, and social access to food that meets their nutritional needs and cultural preferences [7]. In contrast, food insecurity refers to the inability—often due to financial hardship—to obtain enough diverse and sufficient food for a balanced diet, and it is widely recognized as a core indicator of socioeconomic deprivation worldwide [16] [22].
Multiple factors contribute to global food insecurity, including poverty, ecological degradation, geographical barriers, and political instability [29]. One comprehensive classification system used by food policy researchers outlines three primary levels of household food insecurity. These are:
- Marginal Food Insecurity – Households experience anxiety about food running out or face limited options due to financial limitations.
- Moderate Food Insecurity – Budget constraints lead to reduced food quality or quantity, affecting dietary balance.
- Severe Food Insecurity – Individuals reduce food intake significantly, often skip meals, and in extreme cases, go without food for an entire day or more [18] [25].
To better understand and measure food system resilience, the FAO breaks down food security into four main components:
- Availability – The sufficient production and supply of food.
- Accessibility – The ability of people to obtain food through physical and economic means.
- Utilization – The proper use of food based on nutritional knowledge and food safety.
- Stability – The consistent presence of the other three factors over time [12] [40].
Recent studies emphasize that food insecurity extends beyond affordability alone. The COVID-19 crisis, for example, had far-reaching impacts across all four dimensions of food security. Disruptions in supply chains, economic instability, labor shortages, and market closures collectively influenced not just access and availability, but also food use and reliability [6] [20] [33]. In light of these challenges, a comprehensive understanding of food security and its interdependent components remains critical for developing resilient food systems capable of withstanding future shocks.
Table 1: The Four Core Dimensions of Food Security
| Pillar | Revised Description |
| 1. Food Availability | Refers to the presence of sufficient quantities of food, focusing on production levels, storage capacity, and international or domestic trade flows. It addresses the “supply-side” of food security. |
| 2. Food Access | Emphasizes that the presence of food alone does not ensure individual or household food security. Economic and physical access—affected by income, pricing, and market infrastructure—is essential. |
| 3. Food Utilization | Concerns how individuals absorb and metabolize nutrients from food. Proper dietary diversity, food safety, preparation methods, and equitable household food distribution contribute to effective nutritional intake. |
| 4. Food Stability | Highlights the importance of consistent access to adequate food over time. Food security can be undermined by climate events, economic crises, or political unrest that affect availability, access, or utilization. |
2.3 The Impact of COVID-19 on Food Security in North America (Canada and the United States)
The COVID-19 outbreak had a profound influence on both food production and consumption patterns, significantly threatening the security of food access and distribution [12][35]. The pandemic disrupted food-related supply chains globally, endangering the health and well-being of populations, and creating major logistical and economic challenges in delivering food to consumers [27]. In Canada and the United States, rising food insecurity became a visible consequence of the pandemic. Canada, known for its strong agri-food export sector and a vital agricultural economy, experienced severe pressure on its food system [6]. Job losses and reduced working hours during the early stages of the pandemic led to widespread income instability, which experts had warned would escalate the number of individuals living in food-insecure conditions [8]. The crisis emphasized vulnerabilities in Canada’s food landscape, particularly concerning access to safe, high-quality, and consistent food supplies. Despite reassurances from the federal government that food supply chains would remain functional, concerns continued to grow among both food producers and consumers over potential consequences such as increased food prices, delivery delays, and broader economic strain [33][41]. Several threats were noted on the supply side, including transportation system disruptions, labor shortages, and complications at the Canada–U.S. border affecting goods movement [14]. Although the Canadian food system experienced significant shocks early in the pandemic, it gradually regained operational capacity. Still, the COVID-19 experience has exposed its weaknesses, particularly in terms of resilience and long-term sustainability [7].
In contrast, the U.S. food system faced even deeper disruptions. The pandemic exposed critical failures in supply chain infrastructure, particularly due to the collapse of food service outlets such as restaurants and cafeterias, which led to product surpluses, food waste, and supply backlogs on farms [17]. The lack of robustness in supply chain design became evident, as the system struggled to adapt to the dramatic shift in demand from commercial to household consumption [4]. Between April and June 2020, tens of thousands of COVID-19 cases were linked to frontline food workers across sectors like meat processing and agricultural production. An overwhelming proportion of these infections occurred in meatpacking plants, which were among the hardest-hit sectors [25]. In certain regions, such as South Dakota, facilities became significant hotspots for viral transmission, representing a large portion of the state’s total case count [36]. These events resulted in bottlenecks in the distribution of essential food products like poultry and beef, further deepening the crisis of food insecurity during the pandemic [20]. Alongside this, the United States experienced rising unemployment and economic hardship, which further undermined access to adequate food, especially among vulnerable populations [22]. One notable example was the heightened food insecurity observed among university students. Surveys conducted across multiple public university campuses found that students dealing with housing instability or income loss reported higher rates of food scarcity during the pandemic [11] [45]. These findings emphasized the disproportionate impact on specific population groups already facing financial precarity. To address future risks and strengthen food system preparedness, both Canada and the U.S. must harness emerging supply chain technologies. Solutions such as end-to-end visibility tools, collaborative platforms, and smart analytics will be critical for building agile, transparent, and adaptive food supply chains in the post-pandemic era [9] [44] [51].
3.Research Methodology
The methodology adopted in this study is divided into four structured stages. The first phase involved an extensive review of existing scholarly materials and grey literature focused on the subject of global food supply chains, food security, and the influence of the COVID-19 pandemic on these systems, particularly in North America. Search terms such as “impact of COVID-19 on food supply”, “Canada food insecurity during pandemic”, and “US food chain disruptions” were used across academic databases and official repositories. In the second phase, the research narrowed its geographical focus to two North American nations—Canada and the United States—as case study examples. These countries were selected due to the significant roles they play in the international food trade and the rich availability of open-source data. National datasets from government institutions were analyzed alongside findings from recent peer-reviewed studies to assess pandemic-induced changes in food accessibility and supply chain performance. The third step synthesized insights from both literature and data analysis, forming the foundation for a conceptual model aimed at constructing more adaptive and intelligent food supply networks that can withstand future disruptions. Finally, the paper outlines how the suggested framework addresses key challenges caused by the COVID-19 pandemic. Conclusions and forward-looking policy recommendations are included to support better food system resilience beyond the current health crisis.
4.Case Study Analysis
To contextualize the broader impacts of the pandemic, this study undertakes a comparative assessment of food security conditions in Canada and the U.S. These countries were chosen not only for their economic prominence but also due to their interconnected agricultural trade dynamics. Canada currently ranks among the top five global exporters and importers of food products [21], while the U.S. is ranked second for agricultural trade according to global trade statistics published in 2019 [9]. Given the tight integration of supply chains across the U.S.–Canada border, with vast volumes of agricultural goods exchanged regularly, disruptions caused by the pandemic had a ripple effect across both economies [13]. This section draws upon open-source data from national statistical agencies and recent field research to evaluate the severity and scope of food insecurity caused by pandemic-related challenges in both countries [35]. The analysis aims to illustrate how food insecurity surged as a result of systemic shocks to food distribution channels, labor shortages, and economic downturns. Additionally, the reliance of Canada on agricultural imports from countries like the U.S., Mexico, and Brazil highlights the regional interdependence and the cascading effect that any disruption in one part of the network can have on national food systems [44].
4.1 Food Insecurity in Canada During the COVID-19 Crisis
The onset of the COVID-19 pandemic led to profound disruptions in the financial well-being of Canadians. Reduced employment hours, job losses, and other income shocks caused a surge in households struggling to afford or access nutritious food [7]. Before the pandemic, nearly 13% of households in Canada were already dealing with varying levels of food insecurity. This number increased significantly during the health crisis [23]. One national survey conducted between May 4 and May 10, 2020, was part of a broader effort called the Canadian Perspectives Survey Series (CPSS), which sought to understand public response and behavioral trends during the pandemic. A total of 4,600 individuals participated, representing all ten provinces and a sub-sample of the Labour Force Survey (LFS) [11]. Respondents were asked six specific questions related to food experiences, ranging from affordability issues to actual hunger due to lack of food. The findings showed that 14.6% of Canadians lived in households experiencing food insecurity during the 30 days prior to the survey. This equates to approximately one in every seven Canadians. Although most participants reported only one negative food-related experience, about 2% reported experiencing multiple severe food access challenges [17]. Households with children were found to be disproportionately affected, with nearly 19.2% of such households reporting food insecurity. In comparison, households without children reported a lower rate of 12.2% [32]. Additionally, the CPSS data indicated that Canadians who were out of work due to pandemic-related reasons were nearly three times more likely to face food insecurity than those who remained employed during the same period. Approximately 28.4% of respondents not working due to layoffs, workplace closures, or other personal circumstances reported food insecurity, compared to just 10.7% among those still employed [16]. These statistics provide compelling evidence that the economic fallout from the COVID-19 pandemic significantly worsened access to food for many Canadians. The case study highlights the importance of targeted policies and innovative supply chain solutions to safeguard food access during public health emergencies.

4.2 Food Insecurity Trends in the United States During the COVID-19 Crisis
In recent years, food insecurity in the United States has consistently hovered between 11% and 12%, based on national estimates. However, starting in mid-March 2020, a wave of new surveys began to report significantly elevated levels of food hardship—figures that surpassed those observed during previous economic downturns, including the Great Recession [7] [14] [23] [36]. The outbreak of COVID-19 drastically heightened vulnerability to food insecurity across the country [17]. To assess the early consequences of the pandemic on low-income populations, a national online survey was conducted from March 19 to 24, 2020. It focused on U.S. adults earning below 250% of the federal poverty threshold. Out of 2,840 invited panel members, 1,478 completed the survey, yielding a 53% response rate. The study evaluated household food security and other fundamental needs impacted by the crisis [9].
Survey results indicated that only 36% of respondents were food secure, with 20% experiencing marginal food security and 44% classified as food insecure. Among those with low food security, less than one in five (18.8%) reported being able to follow official guidance recommending a two-week supply of food [4]. The findings highlighted that many Americans, particularly those already facing economic difficulties, found it increasingly hard to meet basic needs. The more severe the level of insecurity, the greater the struggle to access essentials. The research concluded that the short-term consequences of the pandemic were intensifying long-standing inequalities and disproportionately impacting vulnerable, low-income groups [27]. By late March and early April 2020, estimates showed food insecurity nationwide had more than tripled to reach around 38% [11]. In response, the U.S. government introduced short-term relief measures. These included enhancements to the Supplemental Nutrition Assistance Program (SNAP), one-time financial assistance of $1,200 per adult and $500 per child, and an additional $600 per week supplement to unemployment benefits as of mid-2020 [35].
Nonetheless, despite these financial interventions, levels of food insecurity remained high. A follow-up web-based survey carried out from June 23 to July 1, 2020, revealed that 43% of low-income households were still experiencing food insecurity. Among families where a single member lost income or employment, 59% were affected. For households where multiple individuals lost jobs or income, the rate surged to 72% [8]. Table 3 (not shown here) offers a comparative overview of food insecurity rates from the March and June 2020 surveys. Both studies used nationally representative samples aligned with demographic characteristics such as age, gender, and ethnicity [12]. The data reinforced calls for long-term, coordinated government interventions. These should include sustained support through SNAP and similar food programs to cushion low-income families from ongoing and future disruptions in food access [38].
5. Suggested Framework for Strengthening Global Food Supply Chains in the Post-Pandemic World
Following the upheaval caused by COVID-19, the need to diversify global food supply chains has become more evident. Lessons drawn from the pandemic have shown that food production systems and agribusinesses must reassess the durability of their supply networks to better navigate unforeseen crises [19]. One of the key strategies for improving resilience is digitizing supply chain operations. Introducing digital technologies can enhance speed, precision, and adaptability in identifying and addressing risks. A fully digital supply chain model supports early risk detection, increases transparency, boosts coordination among stakeholders, and handles escalating complexity in food products [20]. A resilient supply chain, in this context, refers to its adaptability—the ability to absorb shocks and continue functioning with minimal disruption [41]. To create smarter food supply networks, a dual-focus approach is necessary. This involves both responding effectively to the present-day challenges of COVID-19 and establishing a long-term framework that can withstand future uncertainties. Building upon insights gathered in the literature and data analysis, this paper proposes a conceptual model that food sectors in Canada, the United States, and globally can apply to improve their responsiveness. This model is designed to enhance adaptability, ensure continuity in food delivery, and foster system-wide resilience against future health emergencies or supply disruptions. The framework is presented in Figure 2 (not included here), outlining the integration of innovation, sustainability, and digital transformation into existing food supply operations [31].
Table 3: Comparative Results from Two National Surveys on Food Hardship Among Low-Income Adults in the U.S. During the COVID-19 Crisis

| Any household member lost job/income | – | 59.2% |
| Both self and other household members lost job/income | – | 71.9% |
| No loss of job/income in household | – | 39.3% |
Digital Commerce Platforms:
Before the onset of the COVID-19 crisis, a large number of organizations in the food and beverage sector lacked well-developed online retail systems. The pandemic became a major catalyst for expanding the reach and relevance of digital commerce globally. It accelerated the adoption of online shopping for food, particularly fresh produce, and introduced e-commerce solutions to companies and consumer demographics that had previously been slow to adapt. As public health measures like distancing, quarantines, and vaccine-related protocols remain relevant, the demand for strong digital solutions for food purchases is projected to persist into the post-pandemic future. Businesses in the food sector will need to harness modern technologies and predictive analytics to design next-generation e-commerce systems. These platforms should be built on powerful data frameworks capable of capturing vast volumes of real-time consumer activity, analyzing them intelligently, and using the insights to improve both customer experience and logistical performance across the food supply network [12] [25].
Comprehensive Supply Chain Transparency:
A persistent limitation in the global food logistics system has been the absence of full visibility across the entire supply route. However, the emergence of cutting-edge technologies such as blockchain, AI, machine learning, and data science is enabling a shift from traditional, linear models to fully integrated digital supply chain ecosystems. These advanced systems allow food businesses to establish direct connections across their distribution and production networks, improving responsiveness, system agility, and operational transparency. With greater access to real-time data and interconnected nodes, firms are now better positioned to adapt to sudden disruptions such as those caused by the COVID-19 outbreak, ensuring continued flow of goods and services during uncertain times [9] [31] [46].

Utilizing Digital Supply Networks in the COVID-19 Era
In response to the disruptions caused by the pandemic, food-related enterprises must transition from traditional models to more advanced digital supply ecosystems. These digital networks are essential for achieving full supply chain transparency and enabling seamless coordination between producers, distributors, and end-users through real-time information sharing. This connectivity empowers supply chain actors to make better decisions and quickly respond to emerging challenges [7] [21].
Integration of Industry 4.0 Technologies
Industry 4.0 encompasses a broad spectrum of advanced technologies—ranging from artificial intelligence and the Internet of Things (IoT) to cloud solutions, robotics, and data analytics—that work collectively to enhance flexibility and responsiveness in supply operations. To foster adaptability in the food chain, companies need to modernize their infrastructure by embedding IoT-based sensors across production stages. These smart tools collect environmental and product-level data that analytics teams can use to forecast demand, reduce waste from inventory imbalances, and ensure better quality control. Automation and machine learning tools also contribute by enhancing planning accuracy and lowering reliance on manual processes [12] [33] [45].
Adopting Cloud-Driven Platforms
The growing reliance on cloud technologies is reshaping food distribution and logistics systems. Implementing cloud-based applications in supply chain operations helps eliminate communication bottlenecks by offering live updates and detailed tracking of food items in transit. This integration supports interoperability, where devices and platforms across production and delivery can exchange data seamlessly. Such systems help monitor material flow from raw ingredients to final goods and ensure traceability and accountability at every stage. Cloud platforms also make it easier to act quickly in response to disturbances in the network [10] [18] [49].
Decentralized Food Production Models
Decentralization refers to an interconnected but distributed approach where control is shared rather than concentrated in a single hub. Adopting this model for food production can address vulnerabilities associated with centralized systems that were exposed during the pandemic. By establishing smaller farming units closer to where food is consumed, costs linked to transportation and storage are significantly lowered. Additionally, this model offers environmental advantages by reducing fuel usage and emissions. Smaller-scale, localized production improves distribution efficiency, enhances freshness of food, and allows easier reach to underserved populations [15] [28].
Aligning Framework Components with Pandemic-Era Challenges
The outlined framework is designed to directly mitigate several of the challenges identified earlier, particularly in section 2.1. Issues such as labor shortages, cross-border delays, processing plant shutdowns, sourcing interruptions, reduced mobility of agricultural workers, food safety uncertainty, and logistical bottlenecks are among the core focus areas of the framework. These challenges are mapped to specific features of the proposed system in Table 4, which serves to illustrate how each element—be it digital infrastructure, automation, or decentralized models—addresses a distinct weakness exposed by the COVID-19 crisis. This ensures a more adaptive, transparent, and robust food supply system moving forward [9] [34] [42].
Table 4: Addressing Global Food Supply Chain Disruptions through Strategic Framework Components
| Key Component of Framework | How It Resolves COVID-19-Induced Challenges |
| Online Retail Infrastructure | Digital marketplaces helped maintain the food supply chain during lockdowns by enabling customers to purchase food remotely. Live streaming and contact-free transactions allowed producers to showcase and sell products without physical contact. This innovation supported direct sourcing and home delivery, reducing the need for in-person shopping and minimizing transmission risk [7] [15]. |
| Full Supply Chain Transparency | Enhanced visibility across all operational levels—from farms to retailers—made possible by digital tools like AI and IoT helped predict transportation delays, production slowdowns, or workforce shortages. Integrated control systems allowed real-time analysis and proactive response to supply chain blockages, ensuring smoother logistics and better planning during uncertain times [12] [34]. |
| Integration of Smart Manufacturing (Industry 4.0) | Adopting automation and connected technologies enabled flexible, decentralized manufacturing. Smart sensors and robotic systems helped food businesses reduce dependency on manual labor, limit errors, and improve traceability. This technological approach addressed concerns like inconsistent product quality and lack of transparency, ensuring food safety and faster response during emergencies [21] [29]. |
| Cloud-Enabled Operations | Cloud computing tools offered instant access to real-time data regarding inventory, delivery status, and quality control checkpoints. This addressed issues like border delays, harvesting slowdowns, and shipment tracking. The system supports data-driven decisions, enabling rapid adjustments and efficient resource use in dynamic environments [18] [40]. |
| Localized and Decentralized Networks | Shifting to region-based production and distribution networks enhanced resilience by reducing dependence on central systems. Smaller, local facilities ensured food could be delivered faster and more efficiently, especially in urban areas or during crises. This model minimized emissions, reduced transport needs, and gave producers greater autonomy to act on local information [9] [33]. |
7.Conclusion and Future Directions
The COVID-19 crisis has emerged as one of the most far-reaching global disruptions of the 21st century, significantly affecting both food security and the global food supply chain (GFSC). The pandemic exposed critical vulnerabilities within the food and beverage sector, leading to sharp increases in food insecurity across multiple regions. This paper explored these effects through a comprehensive review, focusing on Canada and the United States as representative case studies from North America. These two nations were selected due to their robust economic structures and the extensive food trade that occurs between them, particularly in the agri-food sector. By analyzing publicly available data related to food insecurity and supply chain challenges during the pandemic period, this study confirmed that both countries experienced heightened levels of food insecurity and considerable strain on their food systems compared to pre-pandemic conditions. The analysis addressed the key research questions introduced earlier and provided clear evidence that the pandemic disrupted food supply chains and worsened food access for millions. In response, the study introduced a proposed framework designed to support a smarter, more resilient GFSC capable of adapting to future crises. This research lays the groundwork for ongoing inquiry into the intersection of global crises and food systems. Future investigations should consider expanding the scope to include additional North American nations to form a more comprehensive regional assessment. Moreover, further research is needed to develop measurable models for assessing specific crisis responses—such as the effects of lockdowns, cross-border trade restrictions, and shifts in import/export dynamics—on food systems during global emergencies.
