At the same time, locally based food systems and digital platforms developed as substitute models for resilience.

By literature studies, theoretical frameworks, the results indicate that the pandemic both deepened existing vulnerabilities and accelerated critical transformations within food systems. This paper emphasizes the importance of diversified supply chains, strengthened digital infrastructure, and sustainable consumption practices for enhance long-term resilience. At the end it concludes with policy suggestions for governments, businesses, and households to help prevent future crises while promoting fair and inclusive food systems
