Amidst rapid urbanisation, Asia’s urban centres are increasingly turning to smart solutions as they grapple with worsening air pollution, rising emissions, and erratic weather patterns. What role can data and AI play in shaping more sustainable urban futures? In this episode, ChengHe Guan and Raj Cherubal discuss the future of digital urban transformation, with a focus on smart and sustainable city initiatives in China and India. ChengHe explores how urban sensing techniques and fine-grained data analysis can shed light on pathways to more responsible and inclusive cityscapes. Raj draws on his experience as former CEO of India’s flagship Smart City project in Chennai, revealing the ground-level complexities at the intersection of city systems and climate resilience, as well as the potentials of AI and digital tools for institutional capacity and urban planning. Together, they emphasise that while data and AI are potentially valuable tools, they must be guided by thoughtful policy and inclusive design. They call for the consideration of societal behaviour in planning, stronger global partnerships and cross-disciplinary knowledge sharing to avoid redundant efforts and co-create cities that are equitable, safe, and accessible for all.
