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 economic and environmental sustainability of aquaculture depends significantly on the nature and quality of the fish feed used. One of the main criticisms of aquaculture is the need to use significant amounts of fish meal, and other marine protein sources, in such feed. Unfortunately, the availability of the oceanic resources, typically used to produce fish feed, cannot be utilized indefinitely to cover the worldwide feed demand caused by ever-increasing aquaculture production. In light of these considerations, this study estimates how aquaculture farm economic outcomes can change by introducing insect meal into the diet of cultivated fish. Several possible economic effects are simulated, based on various scenarios, with different percentages of insect flour in the feed and varying meal prices using a case study of a specialized off-shore sea bass farm in Italy. The findings indicate that the introduction of insect meal—composed of Tenebrio molitor—would increase feeding costs due to the high market prices of this flour and its less convenient feed conversion ratio than that of fish meal. Therefore, the expected environmental benefits of using this highly promising insect meal in fish feed do not align with the current economic interests of the aquaculture industry. To our knowledge, this is the first study to investigate this theme, and it must be noted that our findings cannot be generalized widely because a specific case study was used. Nevertheless, our findings suggest that efforts should be made—at least at the farm level—to find profitable ways to encourage the introduction of this attractive alternative to guarantee both economic and environmental sustainability in the near future.

Recreational functions are among the most important practices to improve farmers’ income and to promote sustainability in the rural territories. Two crucial issues are the ability to rationally allocate farm resources and the ability to efficiently produce different sorts of food and non-food goods. Possible cost savings due to the co-presence of different activities can generate positive effects in the creation of value by agritourist farmers. This paper aims to investigate technical efficiency related to agritourism and recreational functions in Sardinia. Based on a sample of 37 farms and using a data envelopment analysis (DEA) approach, we aim to estimate the technical efficiency of double attitude processes, such as those that characterise agritourism practices. Our findings suggest that efficiency can improve if technical inputs are adequately used; however, the scale appears to be close enough to optimal. Furthermore, we estimated that the margins for improving the efficiency are larger for recreational services and that technical factors contribute to efficiency with a different magnitude. Furthermore, we estimated whether agricultural and non-agricultural resources are efficiently allocated. To our knowledge, this is one of the first attempts in Europe at using an efficiency analysis in agritourism.

The importance of aquaculture in reducing pressure on wild stocks in the seas and meeting the demand for fish worldwide has increased greatly in recent years. However, sustainability of the sector can be jeopardized by the incessant use of fish meal as the main source of feed. For this reason, replacing, even partially, fish meal with other feeds such as insect meal is essential to make this sector more sustainable. However, this transition requires consumer acceptance of this innovation, which comes through price, one of the most powerful marketing tools affecting the evaluation of product alternatives (e.g., fish fed with traditional feed or insects) and the final purchase decision. The objective of this study is to explore the acceptable price and the limits of price thresholds of fish fed with insect meal using a direct measure of assessing consumers’ willingness to pay. In particular, the study uses the Price Sensitivity Meter (PSM) of Van Westendorp to evaluate the reaction of Italian consumers to the price of European sea bass (Dicentrarchus labrax) hypothetically fed with insect meal. The results showed a wide acceptable price range, an indifferent price point very close to the price of traditionally fed fish, and a high price stress factor. Consumers have shown considerable price sensitivity, which does not allow the additional costs arising from the use of this sustainable alternative feed to be passed on to them. Consumers with great subject knowledge showed major willingness to pay. The contribution of our study lies in providing detailed insights into the possible prices that consumers are willing to pay for sea bass fed with insect meal and thus on the product’s perceived quality, offering several implications for academics, practitioners, and policymakers.

Today, the transition to a more sustainable model of the agro-food system is increasingly impellent, requiring all actors’ commitment. In particular, small and medium agro-food business (SMABs) play a decisive and central role in the food and economies of national and underdeveloped areas. Our study aims to identify, through desk research, the level of commitment and communication to the sustainability of SMABs operating in southern Italy. In this study, we followed the Food and Agriculture Organization’s (FAO) approach to implementing such a transition, using their principles as a diagnostic tool to interpret business operations. The data were analysed using two approaches: a regime analysis to assess which FAO principles are commonly followed to make the above transition possible, and an extension of the Abraham and Pingali (2020) framework to describe the commitment of SMABs to the Agenda 2030 goals with respect to the behaviour of small and medium enterprises (SMEs). We found that the SMABs’ behaviours are more oriented towards some FAO principles: those that explain their commitment to improving natural resources and livelihoods, fostering inclusive economic growth, and achieving sustainable development goal 7 of Agenda 2030 than towards others. The contribution of our study lies in providing detailed insights into sustainable actions taken by SMABs while testing the FAO’s principles as a new model to evaluate business operations.
