Home gardens are an essential component of the local food system and family farming worldwide. In Indonesia, a home food gardening program was initiated in the early 2010s to optimally utilize home yards for improving the adequacy of food consumption and nutrition intake of households. In the present challenging situation of Covid-19 pandemic, there has been a growing interest in home gardens to help mitigate food insecurity caused by food supply chain disruptions and the emergence of physical and economic barriers that limit access to food. This paper is a review of pertinent literature to find out the characteristics of home gardens and home gardening program in Indonesia and then examine their contribution to each pillar of food security: availability, access, utilization, and stability. The experiences of home gardens worldwide are reviewed to understand the global context of home gardens and food security. Literature reviews found a positive impact of home gardening program on food availability, access, and utilization. However, improving food stability through a home food gardening program is still a challenging task. This finding implies that the positive contribution of the home food gardening program to household food security is largely limited to the program period. Nevertheless, the program is still an important strategy to address food insecurity and nutrition deficiency of low-income households. Future research should assess factors affecting the sustainability of the program to derive viable models applicable in diverse circumstances. There is a need for research to assess the value and importance of home gardens as a coping strategy to reduce vulnerability and food insecurity in the present global Covid-19 pandemic.
