<![CDATA[Food insecurity and childhood stunting remain important public health concerns across the Indonesian archipelago and are associated with disparities in nutritional food affordability, market accessibility, and socioeconomic conditions. Previous studies have primarily examined food affordability and stunting separately, with limited integration through spatial analysis to identify priority intervention areas. This study aims to synthesize empirical evidence on the integration of spatial mapping of nutritional food affordability and stunting prevalence to address regional food insecurity in Indonesia. A qualitative systematic literature review was conducted by analyzing 25 peer-reviewed articles published between 2015 and 2026 from international and national databases. The synthesis indicates that previous studies generally report an association between lower affordability of nutritious foods and higher stunting prevalence, particularly in remote, rural, and eastern Indonesian regions. Previous studies suggest that Geographic Information Systems (GIS) can be used to identify geographic clusters of food insecurity and nutritional vulnerability and may support evidence-based policy planning. Integrating nutritional food affordability, spatial analysis, and stunting indicators provides a comprehensive framework for prioritizing nutrition-sensitive policies, improving food distribution systems, and strengthening regional food security. This integrated approach may support the development of more geographically targeted strategies for addressing regional disparities and informing stunting-reduction policies.]]>
