Despite the extensive literature on Local Agro-food Systems (LAFS), which involves research on local food identity and organisational proximity, the environmental sustainability of these systems has rarely been addressed. This paper develops a new concept called Local Agroecological Food Systems (LAEFS), which focuses the research not only on local food identity, but also on agroecological principles. We aim to conduct a reflexive review of the literature on the conceptual factors attempting to describe the particular characteristics of LAEFS (distinguishing these from LAFS). We explore five axes of analysis: (a) to establish a compromise at the local level between agro-food sectoral specialisation on the one hand and greater cultivated biodiversity and a more diversified economic structure on the other; (b) to geographically and commercially shorten food channels to the fullest extent; (c) to construct new institutional formulae in the fields of logistics, distribution and public procurement for the scaling up of sustainable food; (d) to develop a participatory, bottom-up, multi-stakeholder and multi-level territorial governance; and (e) to reduce the metabolic profile of food systems by reorganising rural-urban linkages. One of the principal objectives of LAEFS should involve redesigning agricultural and food systems at a scale greater than that of the farm (territory or landscape). This requires both a major public policy push and sustainable territorial governance that incorporate an approach based on territory, food systems and agroecology. Full article

Alternative food networks (AFNs) have emerged in response to the conventional industrial food system, which distances and detaches food production from food consumption. Food cooperatives are representative of AFNs where relationships between food producers and consumers are reconfigured. This study examines household food cooperative membership and changes in food purchase behavior using household panel data gathered by the Rural Development Administration of Korea. In particular, it aims to provide insight into the effect of AFNs on consumer food purchase behavior, including expenditure per food category and visit frequency ratio per store format. The ordinary least squares regression model was used. The findings show that depending on the ownership of AFNs, expenditure per food category and visit frequency ratio per store format vary. Food cooperative members tend to purchase less processed food and more fresh vegetables and fruits than nonmembers. Moreover, food cooperative membership significantly influences the decrease in visits to small supermarkets and traditional markets when purchasing groceries. Full article

This paper explores the coordination of the agricultural cooperative to supermarket or E-commerce supply chain, under the condition of quantity loss with a mixed decay function of exponential and logistical distribution. The nature of this process is analyzed, and the corresponding demand and supply functions with single- and multi-stage discount strategies are constructed, respectively, to create a working model. The optimal discount ratios for supermarkets and agricultural cooperatives in decentralized and centralized decision-making modes coupled with single- and multi-stage discounts are calculated, respectively. Finally, a universal optimal strategy is designed, which can be applied to various quantity decay scenarios and makes the discount strategy more generalized. The results show that discounts can coordinate supply chains more effectively; not only would fresh agricultural produce be sold out before it starts to rot, but also the benefit conflicts arising from both supermarkets vs. cooperatives and traditional vs. E-commerce channels could be equilibrated. Further, multi-stage discounts are more difficult to coordinate than single-stage ones, the corresponding optimal discount ratios rely on the initial quantity of fresh agricultural produce in the supply chain, its market share in the traditional distribution channel, the potential market size, retail price, the price sensitivity coefficient of the channel, the cross-elasticity coefficient of prices between different channels, and the properties of the quantity loss. It is concluded that, regardless of what kind of quantity and quality loss occurs, whether decentralized or centralized decision making is selected, or whether the supermarket’s or agricultural cooperative’s discount ratio is considered, a universal price discount consisting of a fixed term and a drift term could both maximize supply chain profit and coordinate this dual-channel supply chain.

Each year, a large amount of waste paper (WP) is generated in Japan, and due to the change in lifestyle with the COVID-19 pandemic, the WP collection and recycling system in Japan faces new challenges. Although the government of Japan has installed WP collection systems, the efficiency of these traditional WP collection systems is too low, and this causes inconvenience to the governments, residents, and other stakeholders. On the other hand, some recycling companies in Japan are trying to establish a nontraditional WP collection system by setting their own WP collection stations in cooperative supermarkets. Yet, the efficiency of this new system has not been clarified. This research aims to investigate the current status, operational characteristics, and the role of recycling companies’ WP collection stations in the Japanese WP collection system. By performing trade area analysis and stepwise OLS regression, this research will evaluate WP collection stations’ efficiency. Moreover, this research will also discuss how the new WP collection system improves WP collection efficiency and residents’ convenience. The results show that WP collection stations efficiency is particularly high in large supermarkets with many parking spaces and long business hours, as well as in areas with many families with children. Recycling companies’ WP collection system could create a system, which can satisfy resident, government, and recycling company interests at the same time. Full article

E-commerce has boosted in the last decades because of the achievements of the information and telecommunications technology along with the changes in the society life-style. More recently, the groceries online purchase (or e-grocery), has also prevailed as a way of making the weekly shopping, particularly, the one including fresh vegetables and fruit. Furthermore, this type of virtual shopping in supermarkets is gaining importance as the most efficient delivery system in cost and time. Thus, we have evaluated in this study the influence of the cooperation-based policies on costs and service quality among different supermarkets in Pamplona, Spain. Concerning methodology, first of all, we carried out a survey in Pamplona having the purpose of modelling the demand patterns about e-grocery. Second, we have developed an agent-based simulation model for generating scenarios in non-cooperative, limited cooperation, and full cooperation settings, considering the real data obtained from the survey analysis. At this manner, Vehicle Routing Problems (VRP) and Multi Depot VRPs (MDVRP) are dynamically generated and solved within the simulation framework using a biased-randomization algorithm. Finally, the results show significant reductions in distance driven and lead times when employing horizontal cooperation in e-grocery distribution. Full article

The monitoring of the Internet of things networks depends to a great extent on the availability and correct functioning of all the network nodes that collect data. This network nodes all of which must correctly satisfy their purpose to ensure the efficiency and high quality of monitoring and control of the internet of things networks. This paper focuses on the problem of fault-tolerant maintenance of a networked environment in the domain of the internet of things. Based on continuous-time Markov chains, together with a cooperative control algorithm, a novel feedback model-based predictive hybrid control algorithm is proposed to improve the maintenance and reliability of the internet of things network. Virtual sensors are substituted for the sensors that the algorithm predicts will not function properly in future time intervals; this allows for maintaining reliable monitoring and control of the internet of things network. In this way, the internet of things network improves its robustness since our fault tolerant control algorithm finds the malfunction nodes that are collecting incorrect data and self-correct this issue replacing malfunctioning sensors with new ones. In addition, the proposed model is capable of optimising sensor positioning. As a result, data collection from the environment can be kept stable. The developed continuous-time control model is applied to guarantee reliable monitoring and control of temperature in a smart supermarket. Finally, the efficiency of the presented approach is verified with the results obtained in the conducted case study. Full article

The penetration of modern supermarkets is believed to be the cause of the declining role of traditional markets and street vendors in Indonesia. Nevertheless, the competition between state-promoted markets and traditional markets is rarely discussed, both adaptation of market institution and strategy of market actors. This research outlined a theoretical understanding of the dynamics of traditional markets, along the concepts of market flexibility as an adaptation strategy and coordination problems as market actor strategies. The researchers empirically reflect the strategies of four traditional vegetable markets that still survive from tight competition—both the market itself as a social institution, and the strategies of actors involved in market transactions. The traditional market builds flexibility by: (1) Specifying commodities, (2) segmenting customers, (3) changing market operating hour, (4) modifying transportation to operate more efficiently, and (5) low cost market management. At the actor level, competition problems are resolved by utilizing an emotional sentiment of friendship social relations; the formation of prices is determined by developing effective networks of information; and the cooperation problem is dealt with by building a system of punishment and reward based on informal mechanisms. This finding verifies the thesis stating that market competitiveness is determined by institutional flexibility against competition and the ability of market actors to build effective social interactions to maintain market sustainability. Based on the above explanation, further research needs to be focused on calculating how much efficiency is built due to market flexibility, both the transaction cost and the production cost in a quantitative manner. At the actor level, it is necessary to delineate the strategies being built, whether based on pure rational or economic and moral or non-economic considerations in solving coordination problems in the market.

As food safety has attracted the widespread attention of society, the quality safety of agricultural products has become an important part of food safety and also confronts multiple challenges. In fact, the safe use of veterinary drugs in the production process has become one of important guarantees for the quality safety of agricultural products. It’s of great significance to regulate the breeding farmers’ safe use of veterinary drugs and to create a safe and healthy production environment for agricultural products. A field survey of individual and large-scale swine breeding farmers in four typical provinces including Henan, Shandong, Jiangxi and Guizhou generated 397 questionnaires. This field survey conducted the internal and external classification of breeding farmers’ safe use of veterinary drugs and defined the breeding farmers’ safe use of veterinary drugs in the light of dosage, type and standardized operation of veterinary drugs. Based on Lewin’s behavior theory, the survey used the structural equation modeling method to systematically examine the generation path of breeding farmers’ safe use of veterinary drugs. The comprehensive analysis reveals that breeding farmers’ knowledge about veterinary drugs, the attitudes toward the government supervision and the market environment of breeding activities all exert some effects on breeding farmers’ use of veterinary drugs. Some suggestions and countermeasures for breeding farmers’ safe use of veterinary drugs are provided as follows: First, more efforts should be pumped into publicity and instruction so that breeding farmers can have a better understanding of veterinary drugs. Second, preferential policies should be formulated to encourage the breeding farmers’ participation in the industrial organizations of swine breeding farmers, and advocate the industrial organizations’ active provision of different technical trainings. Third, the communication and cooperation platform should be created among breeding farmers, slaughter and processing plants and supermarkets, the poultry insurance market should be regulated, and the insurance purchase process should be improved. Fourth, when more subsidies for harm-free and environment-friendly veterinary drugs are provided, more serious punishments should be imposed on the unsafe use of veterinary drugs to offer policy support for the breeding farmers’ standardized use of veterinary drugs.
