Additionally, it introduces the concept of the environment-behavior-health nexus, stressing the importance of understanding human behavior in shaping health outcomes. Methodological challenges in studying this nexus, such as the Modifiable Areal Unit Problem (MAUP) and Uncertain Geographic Context Problem (UGCoP), are discussed, along with strategies to mitigate them using smart technologies. Future work could aim to integrate smart city technology and health-supportive city research to enhance human and environmental health.
