The role of digital platforms in e-commerce food supply chain resilience under exogenous disruptions

Purpose Operational risks can cause considerable, atypical disturbances and impact food supply chain (SC) resilience. Indicatively, the COVID-19 pandemic caused significant disruptions in the UK food services as nationwide stockouts led to unprecedented discrepancies between retail and home-delivery supply capacity and demand. To this effect, this study aims to examine the emergence of digital platforms as an innovative instrument for food SC resilience in severe market disruptions. Design/methodology/approach An interpretive multiple case-study approach was used to unravel how different generations of e-commerce food service providers, i.e. established and emergent, responded to the need for more resilient operations during the COVID-19 pandemic. Findings SC disruption management for high-impact low-frequency events requires analysing four research elements: platformisation, structural variety, process flexibility and system resource efficiency. Established e-commerce food operators use partner onboarding and local waste valorisation to enhance resilience. Instead, emergent e-commerce food providers leverage localised rapid upscaling and product personalisation. Practical implications Digital food platforms offer a highly customisable, multisided digital marketplace wherein platform members may aggregate product offerings and customers, thus sharing value throughout the network. Platform-induced disintermediation allows bidirectional flows of data and information among SC partners, ensuring compliance and safety in the food retail sector. Originality/value The study contributes to the SC configuration and resilience literature by investigating the interrelationship among platformisation, structural variety, process flexibility and system resource efficiency for safe and resilient food provision within exogenously disrupted environments.

The Economics of Food Supply Chain Resilience

Food supply chain resilience has become a priority for policymakers in recent years. Prompted by several systemic disruptions and the increased likelihood of future shocks, significant attention and public financial investment have been devoted to preparing supply chains to be more able to absorb shocks and more nimbly respond in the future. Food and agricultural supply chains have been particularly scrutinized due to widespread shortages and food price inflation of key staples in recent years. Varied perspectives have emerged about the factors that contribute to the resiliency of food supply chains and the interventions that will be most effective. This article reviews the perspectives on food supply chain resilience generally. Furthermore, we attempt to synthesize the methodologies that have been used to study resilience and offer some guidance for economists studying the topic moving forward.

Biosecurity risks to human food supply associated with plant-parasitic nematodes.

Biosecurity in agriculture is essential for preventing the introduction and spread of plant-parasitic nematodes (PPNs) which threaten global food security by reducing crop yields and facilitating disease spread. These risks are exacerbated by increased global trade and climate change, which may alter PPN distribution and activity, increasing their impact on agricultural systems. Addressing these challenges is vital to maintaining the integrity of the food supply chain. This review highlights significant advancements in managing PPN-related biosecurity risks within the food supply chain, particularly considering climate change's evolving influence. It discusses the PPN modes of transmission, factors increasing the risk of infestation, the impact of PPNs on food safety and security, and traditional and emerging approaches for detecting and managing these pests. Literature suggests that implementing advanced biosecurity measures could decrease PPN infestation rates by up to 70%, substantially reducing crop yield losses and bolstering food security. Notably, the adoption of modern detection and management techniques, (molecular diagnostics and integrated pest management) and emerging geospatial surveillance and analysis systems (spectral imaging, change-detection analysis) has shown greater effectiveness than traditional methods. These innovations offer promising avenues for enhancing crop health and securing the food supply chain against environmental shifts. The integration of these strategies is crucial, demonstrating the potential to transform biosecurity practices and sustain agricultural productivity in the face of changing climatic conditions. This analysis emphasizes the importance of adopting advanced measures to protect crop health and ensure food supply chain resilience, providing valuable insights for stakeholders across the agricultural sector.

Food supply chain resilience in major disruptions

PurposeCorona Virus Disease (Covid-19) is a global pandemic that emerged at the end of 2019 and caused disruptions in global supply chains, particularly in the food supply chains that exposed the vulnerability of today’s food supply chain in a major disruption which provided a unique research opportunity. This review explores the current research direction for food supply chain resilience and identifies gaps for future research in preparing for future major global pandemics.Design/methodology/approachThis article presents a review of food supply chain resilience followed a systematic literature review of the business and management-based studies related to the food supply chain in Covid-19 published between December 2019 and December 2021 to identify the immediate issues and responses that need to be addressed in the event of future disruptions in food supply chains due to new global health threats.FindingsThe study revealed the need for more literature on food supply chain resilience, particularly resilience to a major global pandemic. The study also uncovered the sequence of events in a major pandemic and identified some strategies for building resilience to potential future risks of such an event.Research limitations/implicationsThe limitations of this study are apparent. Firstly, the selection of databases is not comprehensive. Due to time limitations, authoritative publishers such as Springer, Emerald, Wiley and Taylor & Francis were not selected. Secondly, a single author completed the literature quality testing and text analysis, possibly reducing the credibility of the results due to subjective bias. Thirdly, the selected literature are the studies published during the immediate event of Covid-19, and before January 2022, other research studies may have been completed but were still in the state of auditing at this time.Originality/valueThis paper is the first study that provides a detailed classification of the immediate challenges to the food supply chain faced in both upstream and downstream nodes during a major global disruption. For researchers, this clearly shows the immediate difficulties faced at each node of the food supply chain, which provides research topics for future studies.

Understanding and Enhancing Food Conservation Behaviors and Operations

This study explores the dynamics of food conservation behaviors and operations, shifting the lens from the prevalent narrative of food waste reduction to a marketing perspective that emphasizes consumer engagement in sustainable operations. Amidst the rapid urban transformation and economic progress of many countries, this research examines factors influencing individual behaviors toward responsible food operations. It aims to delineate the motivational drivers and deterrents affecting residents’ engagement in food conservation and operations, utilizing an adapted framework based on the theory of planned behavior. We employ partial least squares structural equation modeling to analyze responses from 390 residents. We find that perceived behavioral control, subjective norms, and attitudes significantly enhance intentions to conserve food. Moreover, environmental concerns amplify both attitudes and perceived behavioral control, while green marketing communications and knowledge elevate attitudes, environmental mindfulness, and conservation actions. A connection to nature is substantiated as a reinforcing factor for pro-environmental attitudes and operations. Notably, attitudes are identified as a critical mediator among the examined constructs. This investigation enriches sustainability scholarship by introducing a positive behavior-focused approach, advancing the discourse on sustainable operations. It offers actionable insights for market-driven interventions, policy-making (such as China’s lastest national policies on food security and rural region revitalization in 2024), and educational endeavors to mitigate food wastage and reinforce food supply chain resilience globally.

Furthermore, it explores the role of stakeholders, policymakers and international organizations in fostering a collaborative framework for mitigating risks and enhancing the capacity of food systems to withstand and recover from adverse events. The findings underscore the need for a comprehensive approach that prioritizes risk management, fosters sustainable practices and promotes inclusive decision-making to ensure the long-term resilience of food supply chains in the face of diverse and evolving challenges.

Building resilience in European food supply chains: results of a Delphi study

The COVID-19 pandemic and the war in Ukraine have negatively affected the sustainability of the food market and contributed significantly to the increase in agricultural prices. The goal of this article is to present the results of a European Delphi study on enabling factors and barriers to developing robustness within food distribution networks. The paper also aims to identify ways to ensure food security and build resilience in supply chains for European Union (EU) citizens, as well as strategies to protect the agricultural sector. The Delphi theses, the expected timing of their implementation and their impact on selected stages of supply chains were assessed. The paper employs a literature review, the Delphi method and STEEPED analysis to identify factors for increasing the robustness of European food distribution networks. The research findings highlighted crucial factors in enhancing food supply chain resilience, including financial aid to farmers, the use of advanced technologies (like AI, remote sensing, GIS, VR, or drones), and the encouragement of conscious consumption practices. The study revealed that severe weather, inadequate financial support for farmers and insufficient favourable legislation at the national level are the main barriers to achieving resilience in food supply chains. The main recommendations for building food resilience include encouraging localised food supply chains and, advocating for eco-friendly, sustainable production approaches and small-scale agriculture and reducing unnecessary food losses. The originality of the study is reflected in the presentation of the opinions of international experts on developing robustness within food distribution networks in view of the disruption caused by COVID-19 and the geopolitical situation.

Global food supply chain resilience assessment: A case in the United Kingdom

With the development of globalisation, countries such as the United Kingdom (UK) heavily rely on shipping for food imports and supplies. With the unpredictable impacts of black swan events, such as the Coronavirus disease (COVID-19) outbreak and the armed conflict between Ukraine and Russia, which are traditional food export countries, global freight supply chains could dramatically change, which significantly affects the global food supply chain (FSC) resilience, requiring new solutions to be found. Therefore, it is vital to assess a country’s food importing system by sea to ensure its FSC resilience. However, it is challenging to analyse different food supply resilience levels on a national scale given the high uncertainties in the key relevant elements (e.g. food supplies and transportation) influencing FSC resilience. This paper aims to develop a new method to assess FSC resilience at a country level by pioneering the combination of the two most relevant attributes, its production-to-supply ratio and shipping transport connectivity, used to present food supply security separately in the current literature. Within this context, food production and import distance affecting the connectivity of various food supplies are selected to estimate FSC resilience in this study. The findings, including a new index framework to assess national food resilience, significantly contribute to a country’s food security and the rational development of countermeasures and policies when necessary. To demonstrate the significance of the findings, the resilience of the UK FSC is first evaluated in a real case study, followed by a comparative study with Canada, Australia, Democratic Republic of the Congo (DRC) to identify the strengths and weaknesses of the FSCs of different countries. The findings of the studies can be used to monitor FSC resilience of the countries and provide rational policies for enhancing FSC resilience.

Examining the dynamic and nonlinear impacts of public health events on the resilience of food supply chain: evidence from China

IntroductionThe fragility of agriculture makes the food supply chain vulnerable to external risks such as epidemic, conflict, disaster, climate change, economic and energy crisis. The COVID-19 pandemic has spread and continued globally in recent years, resulting in food supply chain disruption and insecurity, which triggers profound reflection on the impacts of public health events (PHEs). Studying the impacts of PHEs on the resilience of food supply chain has great significance to effectively reduce the risks of disruption and insecurity in the future.MethodsBased on the composition of PHEs and the division of food supply chain, this paper adopted the nonlinear Granger causality test to verify the nonlinear causal relationship between PHEs and proxy variables in the food supply chain; then the TVP-VAR-SV model was constructed and its three-dimensional pulse response results were matched with the sensitivity, recovery, and adaptation of the food supply chain resilience to deeply explore the dynamic impacts of PHEs.ResultsPHEs has significant nonlinear conduction effects on the resilience of food supply chain, the impacts of PHEs on the partial sector resilience have significant dynamic characteristics in the whole sample period, and the impacts of PHEs on the recovery and adaptation aspects of food supply chain resilience have structural break characteristics.DiscussionThe differences, dynamic characteristics and structural breaks of the impacts of PHEs on the resilience of food supply chain are caused by the infectivity and mortality of PHEs, attributes of food products, regulation of supply and demand in the market, behavioral decisions of all participants, changes in the policy environment, and coordination and upgrading of all sectors in the supply chain.

A Fermatean Fuzzy ORESTE Method For Evaluating The Resilience of the Food Supply Chain

To study the resilience and driving factors of key players in the food supply chain, this paper applies a decision model based on the Fermatean fuzzy set and improved ORESTE method. Firstly, based on the existing research on food supply chain resilience, the risk influencing factors affecting food supply chain resilience is established through a literature review. Secondly, Fermatean fuzzy sets are used to express and integrate uncertain information, calculate the membership and non-membership degrees of the factors affecting the resilience risk of the food supply chain, and then calculate the score function to obtain the weight of the influencing factors and the risk weight of alternatives. Finally, the improved ORESTE method is used to rank key players, thereby identifying key players in the food supply chain that affect resilience. The results show that transportation and logistics failures, government regulation, and diseases are the three important risk factors with the highest weight coefficient, while water system failure is the least important risk factor. Among the key players, farmers and food processors are considered the most vulnerable key players in the food supply chain, while the most resilient key players are supermarkets and food wholesalers.

The future of the food supply chain: A systematic literature review and research directions towards sustainability, resilience, and technology adoption

In recent years, our food supply chain facing various disruptions shows a need for higher resilience and sustainability. To better prepare for future uncertainties the food supply chain may encounter, it is imperative to understand the status quo of the food supply chain resilience literature, which focuses on deploying digital technology and integrating sustainability in supply chain management. Motivated by this, our study critically reviews the literature on food supply chain resilience against different types of disruptions, identifies research gaps, and provides a reference for the food supply chain to respond to uncertainties more effectively through digital technology and sustainability integration. To fulfil this objective, we perform a systematic literature review of academic journal articles from 2010 to 2020. Our study is novel in investigating different potential strategies to respond to various disruptions, emphasising the role of digital technologies and sustainability. The findings complement existing literature on supply chain resilience and serve as guides to supply chain practitioners facing disruptions. In addition, we investigate possible ways of adopting and optimising digital technologies to enhance food supply chain resilience and indicate areas where a sustainable future can be achieved through a more resilient food supply chain powered by digital innovations.

A balancing act: the interplay of food supply chain resilience and environmental sustainability in American cities

Global food systems must be a part of strategies for greenhouse gas (GHG) mitigation, optimal water use, and nitrogen pollution reduction. Insights from research in these areas can inform policies to build sustainable food systems yet limited work has been done to build understanding around whether or not sustainability efforts compete with supply chain resilience. This study explores the interplay between food supply resilience and environmental impacts in US cities, within the context of global food systems’ contributions to GHG emissions, water use, and nitrogen pollution. Utilizing county-level agricultural data, we assess the water use, GHG emissions, and nitrogen losses of urban food systems across the US, and juxtapose these against food supply resilience, represented by supply chain diversity. Our results highlight that supply chain resilience and sustainability can simultaneously exist and are not necessarily in competition with each other. We also found a significant per capita footprint in the environmental domains across Southern cities, specifically those along the Gulf Coast and southern Great Plains. Food supply chain resilience scores ranged from 0.18 to 0.69, with lower scores in the southwest and Great Plains, while northeastern and Midwestern regions demonstrated higher resilience. We found several cities with high supply chain resilience and moderate or low environmental impacts as well as areas with high impacts and low resilience. This study provides insights into potential trade-offs and opportunities for creating sustainable urban food systems in the US, underscoring the need for strategies that consider both resilience and environmental implications.

Achieving Food Supply Chain Resilience During Natural Disasters Through Industry 5.0 Enablers—Empirical Insights Based on an FsQCA Approach

AbstractThe purpose of this research is to establish the necessary and sufficient conditions for food safety and security during pandemic outbreaks, focusing on the case of COVID-19 to ensure resilience of the food supply chain. The study emphasises on the complexity theory of fuzzy set Qualitative Comparative Analysis (fsQCA), to establish a result-driven definition of Industry 5.0 (I5.0) during and post pandemics. The results of this study revealed that a combination of conditions derived from pandemic policy related reforms and I5.0 enablers will assist manufacturers and suppliers in establishing food safety and security during and post the COVID-19 era in a developing economy. Food safety and security being the goal, based on a survey of 140 food companies, this study provides insights to manufacturers and policymakers to enable selective implementation of I5.0 enabling technologies and pandemic policies.

Inherent and adaptive resilience of logistics operations in food supply chains

AbstractThis study aims to investigate the sources of resilience for logistics operations as it relates to food supply chains and their responses during natural disasters and other disruptions. The literature tends to treat inherent and adaptive resilience as somewhat separate constructs. Thus, this study also aims to provide some insights into the relatively underexamined area of how inherent resilience synergistically works with adaptive resilience to maintain flows for food supply chains in a developing economy context. To address the research aim, two supply chain wide case studies were used to investigate the contribution of logistic activities toward the resilience of foods supply chains in two different South Asian regions. This context was selected as these regions are prone to frequent natural disruptions and other disruptions, and these food supply chains also play a crucial role in economy and providing relief supplies to their communities. Logistics operations play a key role in achieving overall supply chain resilience. The sources of inherent resilience are the network structure, buffer capacity, and strong social connections among the actors. Adaptive resilience is derived from transportation flows, storage, information sharing, and demand management processes. Surprisingly, resilience in this context is achieved despite the relatively low level of integration, an unsophisticated technological landscape and compromised logistics infrastructure. Still, resilience can be enhanced further. This study contributes to the sparse literature that examines logistics activities that influence the resilience of food supply chains in the context of natural disasters and other disruptions. Furthermore, uncovering the substructure of logistics resilience activities, and surprisingly, the synergies between inherent and adaptive resilience, adds to the emerging body of literature.

Transforming Challenges into Opportunities for Qatar’s Food Industry: Self-Sufficiency, Sustainability, and Global Food Trade Diversification

Food trade restrictions pose a serious risk for countries that are heavily reliant on food imports, potentially leading to food crises, inequality, and geopolitical conflicts on a global scale. However, such restrictions may also have transformative effects in promoting food supply chain resilience, security, and self-sufficiency. In this study, a novel econometric analysis is presented, utilizing a data-driven analytical model to investigate the impact of a food embargo on the industry, using Qatar as a case study. A structured and automated food trade database is created using Microsoft Management Server Studio and data visualization software is integrated for automated data discovery. By using a global, trade-based sustainability assessment model, which combines the multi-region input-output (MRIO) analysis with transportation mode-based (sea, road, and air) emissions, the carbon footprint of the dairy food production sector could be estimated. The study shows that the trade embargo on Qatar’s food industry can lead to significant reductions in the annual import of food products, promoting self-sufficiency, and reducing the net carbon emissions of the dairy food sector by nearly 40%. This reduction is not only achieved through food supply chain changes, such as transportation modes, but also by restrictions pushing the country to increase domestic production. Overall, the study demonstrates that a trade embargo, with the support of a well-designed national food security strategy, trade/import diversification, and the use of different modes of transportation for food products, can improve the resilience of global supply chains, self-sufficiency, and environmental sustainability.

Diversifying agrifood systems to ensure global food security following the Russia–Ukraine crisis

The recent Russia–Ukraine conflict has raised significant concerns about global food security, leaving many countries with restricted access to imported staple food crops, particularly wheat and sunflower oil, sending food prices soaring with other adverse consequences in the food supply chain. This detrimental effect is particularly prominent for low-income countries relying on grain imports, with record-high food prices and inflation affecting their livelihoods. This review discusses the role of Russia and Ukraine in the global food system and the impact of the Russia–Ukraine conflict on food security. It also highlights how diversifying four areas of agrifood systems—markets, production, crops, and technology can contribute to achieving food supply chain resilience for future food security and sustainability.

Market structure and resilience of food supply chains under extreme events

AbstractRecent extreme events and the disruptions they caused have made food supply chain resilience a key topic for researchers and policymakers. This paper provides input into these discussions by evaluating the efficiency and resilience properties of the leading policy proposals. We develop a conceptual model of a prototype agricultural supply chain, parameterize the model based on the empirical literature, and conduct simulations to assess the impacts on resilience and economic welfare of four key policy proposals: (i) intensified antitrust enforcement to improve market competition, (ii) subsidization of entry of additional processing capacity, (iii) prevention of price spikes through anti‐price‐gouging laws, and (iv) diversification of production and processing across multiple regions. Results show that some of the policies have potential to improve supply‐chain resilience, but their impacts depend on the existing market structure, and resilience gains often come at the cost of reduced efficiency.

Blockchain adoption or contingent sourcing? Advancing food supply chain resilience in the post-pandemic era

In the post-pandemic era, food supply chains and firms therein are facing unprecedented severe challenges, because once infection is detected, numerous products must be recalled or abandoned, and both suppliers and retailers in the supply chain suffer enormous loss. To survive under the pandemic, retailers have adopted different sourcing strategies, such as contingent sourcing, which, in turn, affect the upstream suppliers and hence the resilience of the whole supply chain. With the rapid development of digital technologies, retailers nowadays can utilize blockchain as a reliable and efficient way to reduce product risk and hence advance the resilience of food supply chains by improving product traceability and inspection accuracy, and making sourcing transparent. In this paper, we develop a game-theoretic model to investigate the interrelation between the retailer’s decisions on blockchain adoption and sourcing strategies. We consider that a retailer originally orders from a risky supplier while conducting an imperfect inspection to detect infected products before selling. The retailer may speculatively keep on ordering from the risky supplier or adopt contingent sourcing by ordering from an alternative safe supplier. The retailer also has an option to implement blockchain to improve the inspection accuracy and product traceability. We derive the optimal retail prices under different sourcing strategies with and without blockchain adoption and then analyze the incentives for sourcing strategy and blockchain adoption. Then, we identify the conditions of an all-win situation for food retailer, supplier, supply chain resilience, and consumers with/without government subsidy. Finally, we extend to consider the situation that some consumers have health-safety concerns and preferences for blockchain adoption.
