The amount of food wasted is a topic of societal and academic interest. As academic research in this area is nascent, there are significant knowledge gaps, which this dissertation seeks to narrow, pertaining to: (1) the measurement of food waste; (2) the human behaviors that lead to wasting of food; and (3) the development of efficacious food waste...

An intervention, which used elements of the theory of planned behavior, was developed and tested in a randomized control trial (RCT) involving households in the city of London, Ontario, Canada. A bespoke methodology involving the direct collection and measurement of food waste within curbside garbage samples of control ( n = 58) and treatment house...
A survey, based on an expanded Theory of Planned Behavior (TPB), was used to indirectly measure self-reported food wasting and its behavioral determinants. This was complemented with directly and objectively measured food waste in curbside garbage samples. Households (n = 189) reported throwing out avoidable food waste a mean of 5.48 times (SD = 5....
Approximately one quarter of the food supplied in the world is wasted across the food supply chain. Almost half of this amount is related to household food waste, which results from mismanagement of consumption. Therefore, the purpose of this study was to investigate the consumer food management behavior in order to reduce food waste. Survey data w...

... Similarly, the reasons of food waste suggested by other researchers are the storage of foods for an excessive period in the refrigerator/deep freeze, expired foods, deterioration of organoleptic properties of foods (formation of mould, etc.), a dislike of eating any previously-cooked meals, purchase of foods in excessive amounts, and inaccurate calculations of portion sizes while serving (Arous et al., 2017;Gaiani et al., 2018;Ghinea & Ghiuta, 2018;Lanfranchi et al., 2016;van der Werf, 2018). The discarding of foods is generally caused by an insufficient level of attention, information and awareness from the individual. ...
This study aims to put forward and discuss the analysis results of various factors on the creation of food waste from households. An online survey application was used, and 1,488 individuals participated in the study. Of the participants, 32.9% stated that they produce 0-1 kg of food waste. The main reasons for food waste were found to be mouldy food, food left in the refrigerator for too long and the date expiration of food. There was a significant negative association between the amount of food waste in households and age, living place, control of refrigerator/storage cabinet, preparation of a shopping list, and the determination of time for food to be cooked and the frequency of preparing meals with fresh foods. On the other hand, there was a significant positive association between the amount of food waste in households and household average food consumption per week, the number of women living at home, frequency of food shopping, buying food that is not needed when shopping, frequency of noticing that you forgot to use food once you used it and stored in the refrigerator/storage cabinet, frequency of ordering food at home, frequency of food preparation with prepared food products, and frequency of thinking that portion size of the dish was large when cooking or serving a meal. Also, it has been found that there is a significant relationship between the amount of food waste and one’s profession, shopping place, and the feeling of guilt when throwing food away (p<0.05). Based on the study results, to prevent waste generation behaviours of individuals, effective initiatives should be carried out through awareness campaigns in various areas.
Literature indicates that littering is a social environmental issue resulting from people’s actions towards the environment. This study was conducted with three families to explore the success of action research and environmental education within a home setup. The intention of the study was to conscientise children towards littering by using progressive environmental action research activities through action research spiral cycles. To know the implication of progressive environmental action research activities at home, the constructivist learning theory and collaborative paradigm, which explored the success of action research and environmental education at home with children, underpins the study. Three out of 14 children served as co-researchers in this study at home after being carefully chosen from seven classes at school. Subsequently, the data of the study was collected from both parents and co-researchers. Interviews, participants’ observations and photographs served as research instruments to collect data. Successively, a coding process and analysis were conducted. The findings of the study reveal that progressive environmental action research activities were successfully implemented to conscientise children towards littering at home. This led the researcher to conclude that if progressive environmental action research activities are conducted through action research, they can empower children to take action towards addressing littering.
