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 encompasses more than just the availability of food; it includes accessibility, affordability, stability, and the utilization of food in ways that promote health and well-being. The concept is closely tied to sustainable development and the functioning of smart cities, where ensuring equitable access to resources and efficient management of food systems becomes a vital part of achieving resilience and inclusivity. Food security is not simply about producing enough food globally; it is also about ensuring that food reaches those who need it, that it is affordable, culturally acceptable, and environmentally sustainable. The first dimension of food security is availability, which refers to the physical presence of sufficient quantities of food of appropriate quality, supplied through domestic production or imports. It emphasizes the supply side of food systems, requiring robust agricultural productivity, sustainable land use, water management, and efficient distribution networks. In the context of smart cities, availability can be enhanced through urban agriculture, rooftop farming, vertical farming, and the use of technology such as precision agriculture. These practices can reduce dependency on distant rural supply chains and contribute to localized resilience. Availability also depends on proper infrastructure, such as storage facilities, cold chains, and transportation systems, which prevent post-harvest losses and maintain food quality. The second dimension is access, which is divided into economic and physical access. Economic access highlights the ability of households and individuals to afford adequate food without compromising other essential needs such as health, education, or housing. Physical access refers to the presence of food markets, retail outlets, and distribution networks that allow people to obtain food conveniently.
