This study investigates the relationship between household food insecurity and food waste in Bogor Regency, Indonesia, focusing on how food security impacts food waste generation. Involving 215 households, the research used the Food Insecurity Experience Scale (FIES) to measure food security, along with waste composition analysis and a 7-day diary to track food waste. Major food waste contributors were cereals (especially rice), tubers, and vegetables, while fruits contributed significantly to inedible waste.
Findings revealed that 18.6% of households experienced food insecurity, with an average food waste of 77 kg per capita annually. An initial negative association was found, suggesting that food waste decreases as food insecurity increases; however, this relationship was not statistically significant after controlling for household income, food expenditure, and education levels. Instead, higher household income was associated with increased food waste, indicating that financial resources significantly impact waste behavior. The study suggests focusing waste reduction efforts on key foods like rice and vegetables, particularly among higher-income households with greater food access.
