Issues and Challenges in Short Food Supply Chains: A Systematic Literature Review

Nurturing Sustainability and Health: Exploring the Role of Short Supply Chains in the Evolution of Food Systems-The Case of Poland

Over the last few decades, short food supply chains and local food markets, where farmers either sell their products directly to consumers or use a limited number of intermediaries, have developed worldwide in rural and urban areas. They complement conventional, often globalized, long food chains where small farmers have little bargaining power, and consumers cannot link the food they buy to a known agricultural producer or geographical area where the food is produced. The advantage of direct sales is that producers can obtain a higher price while consumers have easier access to fresh and seasonal food products. The main aim of the paper is to identify and characterize the spatial concentration of local food systems in Poland and their importance in sustainable development and food policy for healthy eating. As part of this study, an analysis of the statistical data of the Central Statistical Office for 2021 was carried out. Data obtained from the Chief Veterinary Inspectorate as of mid-2021 were analyzed to discuss the topic in detail. Descriptive methods and comparative analyses were used to understand regional differences. Absolute and proportional values were used for the research to enable better comparisons between regions, using the traditional method used in spatial structure studies, i.e., the distribution index (number of entities per 1000 inhabitants). The analysis identified spatial differences and possible implications for food policy and regional development. In addition, data on the number of marketplaces in Polish regions in 2022 were used. The study results indicated that short supply chains in the Polish food system contribute to increasing the availability of healthy local products, which may improve consumer health. However, despite these benefits, the results revealed challenges such as the limited production scale of local suppliers and the need to adapt to changing market conditions.

Sustainable Innovation through Developing Hybrid Agri-Food Supply Chains: A Case in South-Eastern Spain

We analyze the incipient development of short supply chains for fresh fruit and vegetables from conventional agri-food chains, leading to the emergence of hybrid chains. We have sought to answer the research question of how and why hybrid food supply chains has been initiated by studying this phenomenon in south-eastern Spain. We analyzed the 20 main Spanish fruit and vegetable exporters, identifying the 9 that have developed short channels. Subsequently, we conducted a case study of the one considered most relevant, identifying the stages of this short chain, analyzing the tasks to be performed in the different phases of the SCS, studying which are common to both and where the differences in the processes arise. The results show the synergies that make them coexist successfully, such as the sharing of personnel, infrastructures and services, complementarity in the product range, thus avoiding food waste, or knowledge of consumer tastes and needs.

Toward Better Food Security Using Concepts from Industry 5.0

The rapid growth of the world population has increased the food demand as well as the need for assurance of food quality, safety, and sustainability. However, food security can easily be compromised by not only natural hazards but also changes in food preferences, political conflicts, and food frauds. In order to contribute to building a more sustainable food system-digitally visible and processes measurable-within this review, we summarized currently available evidence for various information and communication technologies (ICTs) that can be utilized to support collaborative actions, prevent fraudulent activities, and remotely perform real-time monitoring, which has become essential, especially during the COVID-19 pandemic. The Internet of Everything, 6G, blockchain, artificial intelligence, and digital twin are gaining significant attention in recent years in anticipation of leveraging the creativity of human experts in collaboration with efficient, intelligent, and accurate machines, but with limited consideration in the food supply chain. Therefore, this paper provided a thorough review of the food system by showing how various ICT tools can help sense and quantify the food system and highlighting the key enhancements that Industry 5.0 technologies can bring. The vulnerability of the food system can be effectively mitigated with the utilization of various ICTs depending on not only the nature and severity of crisis but also the specificity of the food supply chain. There are numerous ways of implementing these technologies, and they are continuously evolving.

Who Prefers Regional Products? A Systematic Literature Review of Consumer Characteristics and Attitudes in Short Food Supply Chains

The present work is a selection of empirical studies focusing on the characteristics and attitudes of Short Food Supply Chain (SFSC) consumers. Using a systematic literature review approach (PRISMA), we identified five different aspects of the SFSC within the publications: producer participation, swot, state intervention, attitude and “other”. Based on the findings of studies from the academic literature, the results are quite mixed. Though the number of SFSC-related empirical studies has risen in recent years, there is a lack of SFSC-related data, even in the European Union (EU), where a sustainable agriculture and food system must play a crucial role in the implementation of the Green Deal. Overall, it is hard to name those features that, without any doubt, affect the willingness of consumers to purchase from an SFSC. The studies mostly remarked on age and education; however, even these findings cannot be generalized. Therefore, some consumers of non-global food supply chains could be characterized very well, but these observations could differ in diverse cases because of local factors.

Optimization of Urban Distribution Centres: A Multi-Stage Dynamic Location Approach

Customer demand is dynamic and changeable; thus, optimality of the enterprise’s initial location cannot be guaranteed throughout the planning period in order to minimize site selection cost and maximize service reliability in the whole operation cycle. The enterprise planning period is divided into different stages, and a static location model is established at the fixed stage. In addition, a multi-stage dynamic location model is established by introducing the transfer cost between adjacent stages. To reduce the difficulty of solving the dynamic location model, first, we determined the optimal site selection and allocation strategy for each stage. Second, we designed a novel method that transforms the multi-stage dynamic location problem into the shortest path problem in graph theory. Finally, the Dijkstra algorithm was used to find the optimal dynamic location sequence so that its cumulative cost was the lowest in the whole planning period. Through a case study in China, we compare the costs of static and dynamic locations and the location cost under different objectives. The results show that this dynamic location generates more income (as it reduces cost) in comparison to the previous static location, and different location objectives have a substantial influence on location results. At the same time, the findings indicate that exploring the problem of enterprise location from a dynamic perspective could help reduce the operating cost and resources from a sustainable development perspective.
