This paper analyzes the causes and effects of the COVID-19 crisis, with a specific focus on the food system. Food consumption and production has not only been impacted by the crisis, but it may have also contributed to causing the pandemic. After providing a brief introductory framework, the paper presents the results of a pilot study on the link between COVID-19 and the food system, as indicated by the social media activity of selected European Union (EU) Twitter accounts, measured using an original “theme popularity” metric. Thereafter, a systematic review of the literature is proposed to identify the causes of the rise in popularity of a sustainable food system theme, the potential consequences of the COVID-19 crisis for the food system (targeting the production, consumption and waste disposal phases) and possible solutions, focusing on the circular economy. Challenges and opportunities for policymakers in the short and long term are discussed. A holistic approach is advocated, as the global food system is intimately connected with society and requires deep cooperation among nation states and economic actors.

PurposeThe present paper is aimed at 1) performing a systematic literature review (SLR) on applications in the perspective of sustainable agri-food supply chain (SC) of blockchain technology (BCT); 2) analyzing the selected literature, focusing on the advantages of the sustainable uses of the blockchain of the aforementioned SC and 3) presenting an outlook and research directions capable of addressing unresolved problems.Design/methodology/approachThe SLR was conducted using detailed criteria to identify academic articles. Moreover, specific keywords and databases were used. The time frame considered included the years 2010–2020.FindingsThe review analysis indicates that the use of BCT or BCT supported by ICT/IoT contributes to sustainability of agri-food production. However, this technology can lead to several challenges such as scalability, privacy leakage, high cost and connectivity problems.Research limitations/implicationsThe paper demonstrates that BCT can widely use agri-food supply chain due to its intrinsic characteristics. However, it is not excluded that the criteria chosen may not have identified important articles regarding BCT, the agri-food sector and sustainability.Originality/valueAlthough the body of academic literature published on this topic is expansive, the effect of BCT on the agri-food SC's sustainability aspects has not yet been adequately analyzed. Thus, the article is aimed at investigating how BCT is used in the SC. In particular, the article is intended to update information about BCT and its impact on sustainability.

The studies focused on the use of insects have outlined numerous reasons for using insects as food and feed as an important method to increase food opportunities for consumers. Insects have been emphasized as a food source with a low environmental impact due to the limited requirement for arable land and water, low ecological cost, and high-quality protein provision. In Europe and Western countries, insect farming is a growing business in which, however, some critical economic aspects must be recognized. The sector needs to be adequately promoted to rationally exploit the huge amount of potential. As such, the aim of this study was to analyze the recent research on economic aspects related to insect farming for feed and food production with the purpose of providing evidence of the critical economic points in this emerging sector. The focus was mainly oriented to understanding how insect farming can foster virtuous circular economic processes, specifically considering economic aspects on the basis of the limited literature currently available and the circular economic principles. A circular business model approach was proposed to address the entire insect-based feed and food supply chain from a circular economic perspective. In our opinion, the findings underline some economic research questions that need to be addressed in the near future, and the conceptual approach can be individualized to help increase cost- and eco-effectiveness from a circular economic perspective.

The target 12.3 of the 2030 Agenda by the United Nations (UN) calls for halving per capita global food loss and waste. In this regard, the Food & Drink industry (F&D) could play a crucial role in reducing food waste and improving food safety by adopting healthy and eco-innovation packaging. Thus, this paper aims to investigate the F&D manufacturers’ willingness to invest in packaging innovations, such as active, intelligent, and compostable ones to achieve the UN target. In order to reach the stated objective, a multiple case study methodology was developed and administered to a sample of Italian micro and small-medium entrepreneurs located in the Apulia region. Results show that many firms were aware of their need for packaging innovation and of the available technological opportunity. However, only the F&D manufacturers who showed a Real demand, according to a taxonomy approach which also considers the Potential and Latent demand for the innovation, were effectively prompt to invest. Finally, most of the interviewed manufacturers were willing to invest in at least one packaging innovation, choosing mainly between the active packaging and the compostable one.

The consumption of organic food in the EU remains very low, mainly as a result of the higher price of such food compared to conventional products. To determine consumer preferences, 415 consumer surveys were conducted in Madrid (Spain), using tomatoes as the reference for analysis given their significant market recognition in terms of price, types, origin, and production systems. The data analysis was carried out using conjoint analysis and consumer segmentation techniques, maximum willingness to pay, and market share simulations using the maximum utility method. In addition, to better characterize the consumers, their attitudes towards the environment and their lifestyle indicators were defined. Consequently, 25.2% of consumers were found to be the most willing to pay a higher price to consume organic food. The simulation verified that price is the main problem as regards consuming organic food, with a preference for local markets being identified. In general, it is observed that these consumers have a more positive attitude towards the environment and healthier lifestyles. The implementation of the European Green Deal may have the impact of an additional increase in prices owing to higher production costs. To reduce this impact, it would be advisable to stimulate the economic activity of local markets.

In Sub-Saharan Africa, economic growth is essential for poverty reduction, and pro-poor growth is the renewed focus of today’s political debate. The present paper adds to the literature on the growth–inequality relationship. It provides an in-depth analysis of the potential role of agriculture in promoting pro-poor growth in rural and urban areas compared with that of other activities. This aspect still lacks rigorous empirical support. Using the Nexus project SAMs by the International Food Policy Research Institute, this study identifies the level of ‘keyness’ of 36 activities (12 are agricultural) in nine Eastern, Western, and Central African countries using the inter-industry linkages analysis. Afterwards, it investigates the income distribution multipliers effects of activities growth across households classified in quantiles in rural and urban areas. Therefore, the paper adds to the literature, mainly focused on rural poverty and information on the growth effect on urban poverty, which is important in the context of rapid urbanization and the growing number of poor people in African cities. Apart from country-specific factors, the results confirm the strong integration of agriculture with the economy. The growth of key agricultural activities presents the most pronounced multiplicative effect on the income of rural households in the lowest quantiles. Poor urban households also benefit from their growth, but not to the same extent as rural households with an increase in the rural–urban income gap.

In this study, the life cycle assessment (LCA) principle was performed to estimate the environmental impact of three dairy farms that operate using different farming systems, namely, conventional (CON), organic (ORG), and high-quality (HQ) modes. In Italy, the typical style of high-quality (HQ) farming is commonly included in the conventional system but is more strictly regulated by the Decree of the Italian Ministry of Health N° 185/1991. Although the farms are not fully representative of each conduct, they showed intrinsic peculiarities, e.g., the cow-culling rate of each system. This rate requires a quantification as it may be related to loss of income. Allocation criteria were applied to attribute the quantities of pollutants to the co-products: wheat, involved in the congruence and number of cows culled, the latter being undesirable and therefore necessary to quantify. Analysis of variance (ANOVA) highlighted that the no-dairy products significantly mitigated (p < 0.05) some of the impacts’ categories. The allocation of culled cows decreased the impacts of the CON and particularly those of the ORG farms when the mass mode was adopted. HQ showed values similar to the results without allocation. Overall, the objective of identifying a “marker” of undesirable products, estimated by the culling rate, was partially achieved.

Rural tourism has commonly been identified as one of the main areas of application of the principles of sustainable tourism, but the literature has typically focused solely on the ecological dimension, particularly when referring to agritourism. This study presents a new approach to assessing the “eco-effectiveness” of the evolutionary dynamics of agritourism, as applied in a study of NUTS-2 regions in two European countries (Spain and Italy) that have implemented similar rural development strategies. To this end, a synthetic sustainability index was developed using the Index Decomposition Analysis (IDA) technique. The last period of the European Agricultural Fund for Rural Development (EAFRD) 2007–2013 was chosen for the study in order to analyze the outcomes of a programming cycle focusing on the diversification of agriculture through tourism. The results show that the sustainability of agritourism growth is not homogeneous and has specific features in different regions of the same country. In some cases, there were more similarities with regions from other countries. This tool could help evaluate the impact of agritourism and facilitate comparisons between different regions, in this way supporting the process of transition from a linear to a circular economy.

Even though many studies focus on consumer perception of local food, only limited research concerns mountain areas. This paper aims to fill this gap by concentrating on the potential value of mountain food products, with particular reference to young consumers’ perceptions. To this end, an online survey was conducted on a sample of 4079 University students using a specific questionnaire. Collected data underwent hierarchical cluster analysis, defining four clusters. Respondents were found to consider “mountain products” a fundamental commodity with reference to all related categories of food (cheese, meat, honey, fruits and vegetables) and believed that all stages of the supply chain should be carried out in mountain areas. All of the four clusters also reported a positive perception of mountain products, and they associated mountain foodstuffs with various key concepts, such as sustainable development (32.56%, two clusters), local traditions and specialities (49.11%, two clusters) and health (18.34%, three clusters). Therefore, this study provides useful insights for institutions, by further reinforcing the importance of agri-food products in the collective imagination of consumers and producers in mountain areas by promoting understanding of the characteristics sought by younger generations. Finally, this study contributes to increasing knowledge of mountain food products and related perceptions among younger consumers and expands contemporary literature on consumers in mountain market areas.

Food waste is a relevant global problem due to its consequences on food security, economy, and environmental sustainability. This study focuses, in detail, on finding the main motivation for food waste among the young and the principal actions to prevent it. The paper focuses on Italian reality, since Western countries are partly accountable for wasting large amounts of food. What is more, the focus has been shifted specifically on to the youths and young adults, as they are the portion of the population that are most inclined to waste food. Data were collected using a questionnaire survey performed on a sample of n = 904 Italian consumers. In line with previous research, the results of this study confirm that avoidable food waste comes from three main behavioural antecedents: over preparation, excessive purchase, and inappropriate conservation. The research shows that food waste cannot be reduced by just one-way from the consumers; rather, it goes both ways, between consumers and retailers. Therefore, only holding the consumers accountable and expecting them to solve it will not solve the problem of food waste; marketing and retailers should also consider ethics when it comes to food distribution.
