Community gardening has become an important urban sustainability initiative that integrates ecological restoration with social participation. However, little is known about the psychological and social mechanisms that drive citizens’ willingness to engage in such activities, particularly in densely populated cities with limited green space. This study develops and empirically tests an integrative behavioral model combining environmental psychology, social cognitive theory, and environmental identity theory to explain citizens’ participation in community gardening in Tehran, Iran. Using survey data from 416 residents and analyzing results through structural equation modeling, the study evaluates the effects of six key predictors, including childhood nature experience, connectedness to nature, self-efficacy, outcome expectancy, psychological restoration, and collective environmental responsibility, on willingness to participate. The model explained 54% of the variance in participation, indicating high explanatory power. Five predictors significantly influenced willingness to participate: childhood nature experience, connectedness to nature, outcome expectancy, psychological restoration, and collective environmental responsibility, while self-efficacy was not significant. The findings reveal that engagement in community gardening is shaped more by emotional, restorative, and moral motivations than by perceived capability alone. Theoretically, this research advances understanding of pro-environmental participation by integrating memory-based, affective, and normative dimensions of behavior. Practically, it provides actionable insights for urban planners and policymakers to design inclusive, emotionally restorative, and collectively managed green initiatives that strengthen citizen participation and enhance urban resilience.
