Background and Objective: Although cultural and educational challenges contribute to the rising levels of food waste, public participation plays a crucial role in its fundamental management. This study aims to investigate the significance of citizen engagement and to develop a behavioral model for sustainable household food waste management in Tehran.
Materials and Methods: This study adopts a quantitative research paradigm and was conducted using a survey method. The statistical population comprised 2,239,907 households in Tehran, from which a sample of 384 households was selected based on Krejcie and Morgan’s sampling table, using a stratified random sampling method with proportional allocation. Data were collected through a researcher-designed questionnaire, the content and face validity of which were confirmed by a panel of professors in agricultural extension and education, as well as experts in waste management. The reliability of the questionnaire was supported by Cronbach's alpha values ranging from 0.78 to 0.92. Path analysis using structural equation modeling (SEM) in LISREL software was employed to evaluate the predictive power of the independent variables on the dependent variable.
Results: According to the results of the path analysis and the R² statistic, the variables of citizens' intention toward sustainable food waste management, environmental attitude, environmental awareness and knowledge, place attachment, satisfaction, and social trust collectively explained 67% of the variance in citizens' participatory behavior related to sustainable food waste management.
Conclusion: The findings indicate that citizens' environmental awareness and attitudes play a significant role in their participation in sustainable food waste management. In other words, individuals with greater knowledge of the environmental consequences of food waste are more likely to adopt effective waste management practices. Therefore, the development and implementation of targeted educational programs aimed at enhancing public awareness and fostering positive environmental attitudes are essential. Such initiatives can significantly contribute to encouraging participatory behaviors in sustainable food waste management.
