Abstract	Household food waste is a persistent sustainability problem arising not only from inadequate knowledge but also from everyday routines involving food purchasing, storage, meal planning, portioning, leftovers, and interpretation of food freshness. Urban households are particularly relevant to food-waste prevention because dense populations, complex lifestyles, frequent retail exposure, convenience-oriented consumption, limited storage space, and time pressure can repeatedly create conditions in which edible food is forgotten or discarded. This study examines how behavioral nudges can reduce household food waste without removing consumer choice or relying primarily on financial penalties. A structured integrative review was undertaken using peer-reviewed research on household food-waste behavior, behavioral interventions, social norms, planning practices, visual prompts, food-management tools, self-monitoring, and waste-prevention programs. The evidence indicates that effective interventions generally move beyond information provision and modify the immediate decision environment in which food is purchased, stored, prepared, or discarded. Particularly promising mechanisms include visual “use first” prompts, meal-planning cues, shopping-list implementation intentions, refrigerator organization, smaller portions, date-label clarification, waste measurement, social-norm messages, and feedback on discarded food. Recent studies demonstrate that practical food-management tools combined with social-norm interventions can generate meaningful reductions in self-reported household food waste, while visual prompts such as the OzHarvest Use It Up Tape have produced significant reductions in selected food-waste categories. However, systematic reviews continue to identify limited long-term evidence and substantial methodological variation across household intervention studies. The paper proposes an Urban Household Food-Waste Nudge Architecture integrating pre-purchase planning, point-of-storage visibility, consumption prioritization, feedback, and community reinforcement. It concludes that behavioral nudges are most credible when they make low-waste behavior easier at the precise moment a household decision occurs, while municipal infrastructure, food-system design, education, and measurement remain necessary complementary mechanisms.
