In the European Union legislative proposals for the next Common Agricultural Policy (CAP) the income support remains an essential part of the CAP. This paper analyses agricultural income levels, the role of EU aids in ensuring fair levels of income and how different socio-economic and structural characteristics affect farms’ economic viability. Italian Farm Accountancy Data Network (FADN) data have been processed and economic viability has been assessed by comparing Farm Net Income to a reference income and by estimating a profitability index to check whether the agricultural activities remunerate factors owned by the farmer and his/her family. After an explorative analysis, two multinomial logit models have been estimated to evaluate how structural and socio-economic characteristics affect the likelihood of a farm to be viable with and without EU aids. Both structural farm characteristics and farmer’s production strategies explain the likelihood of a farm to be viable in the short and in the medium-long term. Farms are more likely to be viable as the size increases and the higher the capital intensity, while viability likelihood decreases with the farmer’s age, when the holder is a woman, and the farm is localized in Southern Italy. CAP payments do not modify the factors that affect farm viability but can change their weight.

The ongoing Covid-19 pandemic rapidly and dramatically disrupted household behaviours in almost all areas and, among these, eating behaviours and daily food patterns have also been radically altered. All reported changes have potential effects in terms of food waste, which is a global problem that mainly occurs at household level. Many scholars attempted to understand the antecedents of food waste in the framework of Theory of Planned Behaviour (TPB). In this paper we follow this strain of research by focussing on two different behaviours, suggested by the Waste Framework Directive of the EU, namely (a) reducing servings and (b) using leftovers, which may be predicted by the intention to reduce food waste. An online questionnaire containing the key constructs of the TPB and the concern towards the pandemic was administered to a sample of 201 Italian consumers. Results show that the TPB model was confirmed for both behaviours while the Covid-19 concern had no direct effect. However, in the case of portion reduction, there is a significant interaction between concern and intention not to waste food. That is, the effect of intention on reducing servings is increasing as the level of concern increases. Therefore, some indications on how to address food waste policies are drawn.

Recently, insects have received increased attention as an important source of sustainable raw materials for animal feed, especially in fish, poultry, and swine. In particular, the most promising species are represented by the black soldier fly (Hermetia illucens, HI), the yellow mealworm (Tenebrio molitor, TM), and the common house fly (Musca domestica, MD). Although rapid development is expected, insects remain underutilized in the animal feed industry mainly due to technical, financial, and regulatory barriers. In addition, few works have analyzed consumer and stakeholder points of view towards the use of insects as animal feed. In this article, we summarize the main findings of this body of research and provide a discussion of consumer studies regarding the consumption of animals fed with insects. Our review suggests that consumer acceptance will not be a barrier towards the development of this novel protein industry. Furthermore, we conclude that it will be of interest to understand whether the use of this more sustainable feed source might increase consumer willingness to pay for animal products fed with insects and whether the overall acceptability, from a sensory point of view, will be perceived better than conventional products. Finally, the main challenges of the feed farming industry are addressed.

Many studies have explored the antecedents of food waste in the framework of the theory of planned behavior (TPB). Scholars have also made efforts to add explaining variables to the original TPB, with mixed results; they often fail to demonstrate the incremental validity of the extended models. In the current study, we sought to assess whether an extended TPB model including social emotions and Good Provider norms could predict intention to reduce food waste. We also measured two behaviors which may be predicted by intentions to reduce food waste: (1) reducing servings and (2) using leftovers. The results show that social emotions help explain leftovers utilization, whereas the Good Provider norms are inversely correlated to the reduction of servings. Compared to the traditional TPB model, the extended version has more predictive power, especially as regards reducing servings.

The European Union (EU) and the Southern Common Market (Mercosur) free trade agreement (FTA) aims to increase regional trade and major integration between the regions; after decades of negotiations, in 2019, finalization of the agreement was reached. However, there are several blockages from both parties in the ratification process: whilst few EU members the criticize environmental and sustainability issues within the agreement, the Mercosur partners oppose the imposition of sustainability standards onto the region without adequate financial support. On this topic, the literature is still too poor to build a systematic literature review; thus, the present analysis follows a quasi-historical approach considering the major steps of the EU–Mercosur FTA looking both at the scientific and gray literature. The study underlines how environmental and sustainability issues are at the core of the European policies; thus, themes such as deforestation and pesticides could be a dealbreaker in the ratification of the agreement. For the EU, the FTA with Mercosur could mark a new step in the race towards it being a new “global standard” for sustainability and production.

Current estimations showed that the number of people affected by hunger doubled in the last two years, reaching 9.8% of the global population. According to FAO, in order to satisfy the demand for food in the next few years, it will be necessary to double food production. Moreover, the call for a change in dietary patterns has been raised, showing how the food sector is responsible of 1/3 of climate change where meat-based diets or overconsumption of meat play an important role in the negative environmental impact. Consequently, there is a growing concern in how to achieve the goal of increasing food productions without exploiting environmental resources and to explore the production and use of alternative resources, such as insects. Insects are gaining interests both as food and feed not only to reduce the environmental costs in feed production for common livestock, but also to reduce farmers' dependence on traditional protein sources. In this work we aimed to provide an overview of the state-of-the-art upon insect studies, highlighting the most important results obtained from both an industrial and market perspective. The legislative framework concerning edible insects as food and feed is also analyzed, with the final purpose to highlight recent reforms, relevant case-law as well as unsolved regulatory challenges. From a normative perspective, regulatory efforts are still required to fully take advantage of the potentialities of insects-industry. From a consumer point of view, consumers' willingness to pay a premium is going to be a key issue for economic sustainability of the insect farming chain. To meet the food and feed security challenges, insects will have to be considered all-around, including applications in the food, feed, and other sectors. We believe that this review is an important contribution to the field of food science and will be of interest to researchers, food industry professionals, and policymakers in order to prioritize research questions and help communicate scientific knowledge to a broader audience.
