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 not merely about the availability of food but also about its accessibility, affordability, stability, and proper utilization. In the context of sustainable development and smart cities, food security becomes crucial as urban populations are expanding rapidly and traditional food systems are under stress due to climate change, land degradation, and socio-economic disparities. Ensuring food security is therefore essential to creating resilient and inclusive urban environments that prioritize human well-being and ecological balance. The first key dimension of food security is food availability. This refers to the supply side of food systems and ensures that sufficient quantities of food are consistently produced or imported to meet the needs of the population. In rural areas, availability is linked to crop yields, livestock production, and natural resource management, whereas in urban areas, it is closely tied to supply chains, storage facilities, and transportation infrastructure. Smart cities can improve food availability by integrating urban agriculture, rooftop farming, hydroponics, and vertical gardens into their planning models. These technologies reduce dependency on distant agricultural zones and enhance local resilience. Moreover, digital monitoring of food stocks, satellite-based crop forecasting, and blockchain-enabled supply chains further ensure transparency and minimize post-harvest losses. The second dimension is food accessibility, which focuses on whether individuals have the economic and physical means to obtain food. Even when food is available at the national or city level, gaps in income distribution, inflation, or logistical challenges can prevent certain groups from accessing it. Smart cities can address accessibility issues by promoting _________ ____ _______ ______ ______ __________ __________ ____ __________.
