Food security refers to a condition in which all individuals, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life. It is a multidimensional concept that goes beyond the mere availability of food and integrates aspects such as accessibility, affordability, utilization, and stability of food supply. Within the framework of sustainable development and smart cities, food security becomes even more significant because urbanization, environmental stress, and resource constraints pose challenges to ensuring equitable and continuous access to nutritious food. As cities grow more complex, the efficient management of resources, adoption of technology, and smart governance practices play crucial roles in guaranteeing that food systems remain resilient and inclusive. The first dimension of food security is food availability, which refers to the physical presence of sufficient quantities of food within a region or community. Availability is ensured through agricultural production, food imports, public distribution systems, and efficient supply chains. In the context of smart cities, technological interventions such as precision agriculture, vertical farming, hydroponics, and urban agriculture contribute to enhancing food production even with limited land resources. Smart logistics systems supported by real-time data, artificial intelligence, and automated processes strengthen food supply chains, reducing wastage and ensuring timely delivery of food products. Sustainable development also promotes resource-efficient agricultural practices, conservation of biodiversity, and climate-resilient crop varieties to maintain steady and reliable food availability. The second dimension is food access, which denotes the ability of people to acquire adequate food for a nutritious diet. Access is influenced by household income, food prices, market systems, and distribution networks. Economic and social access must be supported equally to ensure that marginalized and low-income populations are not deprived of essential food resources. In smart cities, digital platforms for food
