Digital transformation is reshaping cities, integrating smart technologies to enhance resilience, sustainability, and inclusivity. The transition toward Smart and Sustainable Cities (SSC) aligns with global sustainability frameworks, emphasizing participatory governance and technological innovation. However, disparities persist, with 2.6 billion people lacking internet access and women disproportionately affected by the digital divide. To ensure equitable urban development, smart sustainable cities must prioritize people-centered approaches, embedding digital inclusion in planning. Arab and European cities share common goals but face distinct challenges shaped by their unique socio-economic and technological contexts. Regional efforts are increasingly focused on leveraging digital tools to enhance governance, mobility, sustainability, and inclusion. Successful digital transformation requires strategic leadership, targeted investment, and policy frameworks that integrate smart solutions into broader urban resilience planning.
