How to Exploit Sustainable Food Consumption Habits of Individuals: Evidence from a Household Survey in Izmir, Türkiye

Sustainability

Sustainable production and consumption in the food supply chain are critical for the United Nations’ sustainable development goals (SDGs). Therefore, it is significant to identify the factors that shape individuals’ food consumption behaviour. Türkiye prioritises sustainable food consumption and the prevention of food loss and waste as a national focus. Accordingly, this study aims to identify the drivers of individuals’ food consumption habits in Türkiye through a survey with the participants being households in Izmir, the third most populous city in Türkiye. More specifically, the study has two main objectives: (i) to identify the factors influencing households’ food consumption preferences and (ii) to demonstrate how the factors concerning sustainable food consumption interact through a survey conducted in Izmir. Based on the state-of-art literature, an online survey was completed by 515 respondents in Izmir. Through an analysis of the survey responses, this study provides a desc...

DergiPark (Istanbul University), 2020

The objective of this study was to evaluate the knowledge and behaviour of individuals aged 18 years or above on the subject of sustainable nutrition. The study was conducted between April and May 2019 and involved a total of 202 adult individuals (85 female, 117 male), all of whom are resident in Istanbul and over 18 years of age. The socio-demographic characteristics of the participants, their knowledge on sustainable nutrition, nutritional behaviours and food preferences were determined using a questionnaire. 64,40% of the participants with an average age of 32,60 ± 13,20 had not heard of the concept of sustainable nutrition concept before. While there was no statistically significant difference between gender and being aware of the concept of sustainable nutrition, it was found that women exhibited more sustainable nutrition behaviours compared to men (p <0.05). It was observed that the participants learned the concept of sustainable nutrition mostly from health professionals (31.9%) and social media (26.3%). 39.1% of the participants responded that they agreed with the statement "I consume vegetables and fruits grown during the season" and 36,60% of them agreed with the statement "I consume fish caught during the season with appropriate methods". Most of the respondents (44.50% and 34.60% respectively) agree with the statements "I'm careful about not wasting the food" and "I use economic foods". 44.50% of the respondents agreed with the statement "I have less food waste".

Determination of the factors affecting the amount of food waste generated from households in Turkey

Future of Food: Journal on Food, Agriculture and Society, 2021

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.

Factors affecting food waste awareness in Turkey. The case of Çorum province

Eastern Journal of European Studies

Every year in the world, a significant amount of food is wasted at the consumption stage. Since food waste awareness is the determinant of food waste behaviours, the aim of this paper is to determine the effect of materialist values, personality, religious norm, food choice, food expenditure, recycling and environmental awareness on food waste awareness. Survey data were obtained from consumers in urban areas of Çorum in March, April and May 2019. Structural Equation Model was conducted to determine the factors affecting food waste awareness of consumers. According to the results of the path analysis, religious norms were influenced only by personality, while environmental awareness was influenced by food expenditure and recycling. Although recycling was positively affected by environmental awareness, food expenditure and food choice, it was negatively affected by materialist values. The most important way to reduce food waste is to raise environmental awareness. Consumers should be informed about the impact of recycling, food expenditures, materialistic values and food choice on the environment in order to increase environmental awareness of consumers.

Sustainable Consumption of Food: Framing the Concept through Turkish Expert Opinions

Sustainability, 2021

The scarcity of natural resources together with the exponentially increasing world population has made the sustainable consumption of food (SCF) a crucial issue, as it has impacts on a variety of environmental, health, economic, and social dimensions. Considering the rarity of a holistic view in previous studies, this study aims to assess the current situation in sustainable food consumption and develop suggestions from all aspects, depending on the opinions of experts. In this direction, semi-structured interviews are conducted with 25 experts from Turkey to frame the concept of SCF, reveal the level of consumers’ awareness, and provide suggestions to support SCF implications. Experts have considered SCF from ecologic, social, economic, and health perspectives; ecologic aspects being the most important, followed by economic and social perspectives. Deficits on the consumer side are lack of awareness, unplanned shopping, and mistakes in post-consumption behavior. Lack of awareness a...

Food wastage in Turkey: an exploratory survey on household food waste

Journal of Food and Nutrition Research 4/8: 483-489, 2016

Increase in food demand, mainly due to population growth and diet changes, is putting an increasing pressure on food system and food security. In this framework, food losses and wastes (FLW) together create one of the main causes of food systems unsustainability. The two differ on the fact that food losses refer to the part of food that is lost along the supply chain before reaching final consumer while food waste represents the waste of food by final consumer. This paper focuses on the role of demographic, social and economic factors affecting household behavior related to food waste (FW) and explores some factors which can play an important role in tackling food waste issue in the case of Turkey. The paper is based on an online survey with 150 Turkish respondents in January-March 2015. The sample was not gender balanced since 71% of them were females. About two fifths of the respondents (38%) belong to the age group 35-44 years and 62% of the sample has a high level of education (master and PhD). The fact that the majority of the respondents are employees (70% of the sample) in the big cities of Turkey shows how the pace of the metropolitan life structure affects consumer food consumption habits and orient purchases towards supermarkets. The results of the survey show that still 95% of the respondents are responsible of FW and 90% think that food waste increases during the month of Ramadan. Nevertheless, about 50% of respondents declared the willingness to throw less away and ask for better information about the negative impacts of food waste on the environment and on the economy. Preventing bread waste campaign of the Ministry of Food, Agriculture and Livestock was launched in 2013 in order to increase consciousness of the society towards bread waste which is quite important in Turkey. Similarly, there are some other initiatives on both national and local level with the objective of informing people about the food waste, sustainable food consumption and reuse of the food through food recipes.

Determinants and Preventive Strategies to Reduce Food Waste in Households

International Journal of Current Science Research and Review

Reduction and better management of food waste affects food security at the household level. Various efforts to increase availability by optimizing production have been carried out but it will be more difficult if it is not accompanied by a reduction in food waste which tends to increase, especially at the consumer level. This study aims to examine how behavior and preventive strategies to reduce food waste in households from various literatures can be used as educational materials or the basis for food waste management programs from households. This Systematic Review study was conducted using the PubMed/Medline, Science Direct, and Google Scholar search databases. Search was limited to articles in peer-reviewed journals, written in English and Indonesian between 2013 and 2022. Publications older than 2013 were not included in compiling the study. After the literature was obtained, then the articles were filtered by title and abstract, including filtering out irrelevant and duplicati...

The Need for Consumer-Focused Household Food Waste Reduction Policies Using Dietary Patterns and Socioeconomic Status as Predictors: A Study on Wheat Bread Waste in Shiraz, Iran

Foods

Current household food waste (HFW) reduction plans usually focus on raising consumer awareness, which is essential but insufficient because HFW is predominantly attributed to unconscious behavioral factors that vary across consumer groups. Therefore, identifying such factors is crucial for predicting HFW levels and establishing effective plans. This study explored the role of dietary patterns (DP) and socioeconomic status (SES) as predictors of HBW using linear and non-linear regression models. Questionnaire interviews were performed in 419 households in Shiraz during 2019. A multilayer sampling procedure including stratification, clustering, and systematic sampling was used. Three main DPs, i.e., unhealthy, Mediterranean, and traditional, were identified using a food frequency questionnaire. Results indicated that a one-unit rise in the household’s unhealthy DP score was associated with an average increase in HBW of 0.40%. Similarly, a one-unit increase in the unhealthy DP score an...
