UN International World Cities Day 2025: Advancements in Smart Cities: AI, Data, and the Blueprint for Sustainable Living

Urban studies and planning have been fundamentally transformed by the emergence of smart city initiatives, which blend advanced technologies such as artificial intelligence, big data, and the Internet of Things into the fabric of urban life. Despite technological progress, global cities continue to grapple with critical challenges regarding housing, infrastructure, environmental sustainability, and social equity. The prevailing discourse now questions how smart innovations can move beyond efficiency and automation to meaningfully serve the needs, rights, and aspirations of all urban residents, particularly marginalized groups. Current studies indicate that while many cities successfully leverage technology for urban management, gaps persist in translating these advancements into tangible improvements for vulnerable populations, as well as in achieving genuine inclusion and community engagement. The latest research underscores a growing consensus on the urgent need for frameworks that prioritize people’s well-being, ensure equitable access, and bolster resilience amid crises. However, a lack of comprehensive, people-focused models for integrating technology into urban planning remains a significant challenge for researchers and policymakers alike.

This Research Topic aims to inspire and showcase research that places people at the core of smart urban transformation, particularly as cities worldwide mark the United Nations World Cities Day 2025 theme of “people-centered smart cities.” The objective is to explore and elucidate how smart technologies, data-driven governance, and AI can be harmonized with inclusive urban policies, participatory planning, and equitable service delivery. Contributors are encouraged to address questions such as: What methods best empower communities through digital innovation? How do city leaders balance technological advancement with diverse urban needs and human rights? Which metrics should define success in people-centered smart city strategies?

The scope of this Research Topic is focused on interdisciplinary, cross-disciplinary, and practical approaches that emphasize the integration of technology and data analytics within inclusive and resilient urban frameworks. We seek to anchor the discussion in evidence-based strategies that bridge the digital divide and prioritize underserved populations. To gather further insights in the global pursuit of equitable, resilient, and sustainable cities, we welcome articles addressing, but not limited to, the following themes:

- Human-centric approaches to smart city design and governance
- Community participation and co-creation in digital urban planning
- Socio-technical frameworks for equitable access to urban services
- Data-driven resilience strategies for crisis response and adaptation
- Case studies on integrating AI and data for marginalized and vulnerable groups
- Policy innovation for inclusive and sustainable urban transformation
- Ethical considerations and privacy in widespread urban digitalization

Submissions may include case studies, innovative methodologies, perspectives, and policy analyses that amplify the voices of diverse urban populations and highlight actionable solutions.
