To achieve the goal of reducing consumer-related food waste in developed countries, it is necessary to have an in-depth understanding of the factors shaping food waste, both in the household as well as at the point of purchase. Despite a growing number of studies on the subject, especially in recent years, the evidence on drivers of food waste and barriers to its reduction is somewhat conflicting. The current paper contributes to existing knowledge on food waste behaviour at the consumer level, providing original results from a direct survey conducted with a sample randomly selected in southern Italy to reveal consumer awareness, concerns and intentions towards food waste and to ascertain the existence of different consumer profiles with similar food waste behaviour. Since southern Italian regions have been shown to produce lower levels of food waste than regions in northern Italy, an in-depth analysis of the drivers behind food waste in this area could be considered an interesting case study. Our findings showed the existence of several consumer behaviour profiles that influenced household food waste generation. Strategies to reduce waste should take such differences into account in order to promote changes in food waste behaviour.Sustainability 2020, 12, 1495 2 of 13 the household level make it difficult for commercial actors as well as policy makers to develop effective food waste reduction campaigns [6].In order to reduce food waste in developed countries, it is necessary to gain an in-depth understanding of the factors determining food waste at the consumer level, both in the household as well as at the point of purchase. Identified social drivers connected to consumer behaviour and lifestyles are related to (a) unconscious preferences, such as preferences for certain aesthetic standards or food types, that can be difficult to modify; (b) individual behaviour that may be modifiable through information and strengthened awareness; and (c) sociodemographic factors [3,4,7].Regarding individual behaviour, consumers' routines related to shopping and consumption constitute one of the main drivers of food waste, such as food overprovisioning during shopping, overpreparation and incorrect storage [8]. Among the causes identified for overprovisioning, the literature includes bulk purchases but also marketing and sales strategies implemented by producers and retailers [7,9]. Extensive research shows that communication strategies as well as promotional offers have a considerable negative effect on individual wasteful behaviour, prompting consumers to buy more than actually needed [5,[10][11][12]. Other studies have highlighted that individual wasteful behaviour is also driven by factors related to current legislation or policy. Misinterpretation of date labels, for example, or lack of understanding and following labelling instructions for proper storage are recognised as prominent drivers [4,5]. Previous studies showed that European consumers seem to be very confused and show difficulty in interpreting the actual meanin...

This study frames the household food waste challenge in the microeconomic theory context by proposing a model that considers food waste a consequence of inefficient consumer choices. A data envelopment analysis (DEA) methodology was applied to factor consumer's efficiency level dimension, starting from data collected through a web survey conducted in Italy with a sample of 530 individuals responsible for their households' food-shopping. The findings confirm that food waste is a complex issue, affected by both behavioural and psychological factors, synthesized in three indices constructed with fuzzy analysis. The results show that the shopping behaviour index generates a higher average efficiency score for food waste minimization than the food waste concerns and moral attitudes indices. Furthermore, those drivers have different efficiency levels in reducing food waste with reference to gender, age, family composition, and educational level. The results have several implications for policymakers: they highlight the need to implement tailored educational and information campaigns that consider the most important targets identified, such as large families with children, young people, and men.

Wildfires constitute a serious threat for both the environment and human well-being. The US fire policy aims to tackle this problem, devoting a sizeable amount of resources and resorting extensively to fire suppression strategies. The theoretical literature has established a link between climate conditions and wildfire incidence. Using state-level data from 2002 to 2013 for the USA, this work proposes a wildfire incidence indicator and runs a generalized spatial ordered probit model in order to test the findings of the previous literature empirically. Moreover, this article investigates the extent of spatial spillovers in the climatic covariates. The results highlight a significant impact of precipitation and temperature on fire incidence and provide some evidence of the role of spatial spillovers. In particular, transitions from lower to higher wildfire incidence levels are significantly encouraged by increases in local temperature and significantly discouraged by increases in both local precipitation and lagged precipitation. The present analysis complements the recent literature, confirming the previous findings with a solid empirical investigation and offering a policyoriented picture of wildfire risks all over the USA.
