<p>Rural households in Vietnam are significantly vulnerable to environmental and economic shocks that threaten income stability, sustainability, and food security. Therefore, a deeper understanding of the factors that strengthen household resilience in the country’s rural regions is essential. While the direct effects of shocks on food security are widely recognised, the mitigating role of information access, particularly in underserved rural areas of emerging economies, receives far less attention. This study addresses this gap by examining how information access impacts household food consumption in rural Vietnam. To address the endogeneity problem and facilitate cross-level interactions, we employed multilevel models, a propensity score matching approach, and a rich dataset from the Vietnam Access to Resources Household Survey. The findings indicate that improved access to agricultural and market information significantly increases households’ reliance on self-produced food, thereby mitigating the adverse impacts of droughts, typhoons, and other environmental shocks. Notably, multilevel models demonstrate that the effects of information access on rural households’ food consumption are more pronounced in communities with strong institutional and social capacities. This community-level heterogeneity suggests that information systems function as not merely individual resources but also collective assets shaped by local engagement, infrastructure, and digital readiness. These findings support several actionable policy directions that align with Vietnam’s evolving rural development and resilience strategies, including enhancing digital information infrastructure and implementing climate resilience strategies to bolster household food resilience against environmental and economic shocks.</p>
