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.

The COVID-19 epidemic has exerted an impact on the global food supply chain,and also has contributed to the tendency of food hoarding and short supply;strong food demand has led to a rapid rise in international food prices,which has put enormous pressure on China's food import,and domestic food price showed a rise trend accordingly.In order to ensure sufficient and stable supply of China's food market,it is necessary to adhere to the food security strategy of"food self-sufficiency"for a long term.In the spring agricultural production,Shandong Province has taken effective measures to stabilize food production and achieved good results.It has not been greatly affected by the COVID-19 epidemic;however,under the continuous spread of foreign epidemics,we must adhere to the dual hard core operation of epidemic prevention and production,and explore the establishment of technical specifications for agricultural production under normal conditions for epidemic prevention and control to ensure the food security.

The outbreak of COVID-19 has brought about another age on world as the human civilization is restricted in many aspects of everyday lives.There is no exception in the sector of food production and the supply chain of food.Due to constraints on demand,shutting of food production facilities,financial limitations,enterprise operations and delivery of different food items have been interrupted in the food supply chain.Every nation must comprehend the importance of the situation according to the spreading scenario of the ongoing pandemic.The probability of transmission via the food sector is regarded inconsequential,and the public authorities do not believe it necessary to follow COVID into workplaces.The unfavourable effects on the climate,the food framework and the people of the foodstuffs network are evident.An installation for the food supply chain should focus on amenities such as maintaining the safety and health of employees and changing working circumstances.This paper aims at discussing the effects of COVID-19 on the socio-economic status of human being including the negative impacts on the agriculture and food supply chain.

This paper sets forth the concept of traceability, its importance in improving added value of food and security of food supply chain. On the basis of explaining the structure of a food supply chain and analyzing the process of request and response of information, the paper provides a software architecture of a distributed traceable system of food supply chain, this architecture is based on web service, XML and related technologies. Then, the paper discusses robustness, security and performance of response time which are related to this software architecture. In conclusion, the paper points out that the future studies on traceable system in food supply chain will focus on two issues, one is how to improve the capability of each node in learning traceable information from others;the other is the study of dynamic strategies to minimize the access delay in the traceability systems.

food supply chain involves in the production, consumption, processing, circulation and other links of primary agricultural. Any improper control of links will affect the final quality of products;even jeopardize the health of consumers. So the treatment of food supply chain safety relied on the concerted efforts of all participants. The establishment of risk-sharing, benefit-sharing of safety control supervision system of food supply chain is the primary work of the whole society. This supervision control information system which designed for food supply chain is studied in this article.

Traceability systems are key to assuring food safety,creating a benefit for food supply chain components.Currently,the appearance of new technologies such as IoT and Big Data Analysis leads to a new generation of more functional,but complex,traceability systems.Organisational models based on cooperation of multiple small/medium size agents,for example of small/family farming cooperatives,play an important role in high standard agricultural production and commercialization processes.These function as both social and economic networks,with high social and economic impact in the rural areas.The case of Almeria as an example of this model was used to analyze its cooperative model.The actual traceability systems in the Almeria model were studied,taking account of the different networked agents and their interrelation.This study includes two main parts:a)analysis of the net-chains that constitute the food supply chains and their different relationships,and b)actual traceability.The next step studied how the net-chain model,including many diverse agents,may be applied to develop a new generation of traceability systems based of IoT and Big Data.This implies extending the special and functional scope of the actual systems and defining clear rules of exchange of the results of the Big Data Analysis,taking account of the adequate Privacy Rules.This work analyses the current organisation as a base for a new generation of traceability systems considered in the European project IoF2020(Internet of the food and Farm 2020).Some parallels between Almeria’s model and certain areas in China,mainly in the areas of Beijing-Tianjin-Hebei and Shandong were detected.Another of the objectives of this work is to deepen the understanding of these similarities and analyze the possible adaptation of the results from Almeria to China.
