This bilingual online event (Portuguese–English), organized by participants of the International Visitor Leadership Program (IVLP) – Sustainable Cities, proposes an exchange among urban professionals from diverse cultural and technical backgrounds. Rather than focusing on a single country or case study, it highlights the positive effects of collective learning in interpreting urban challenges and co-imagining sustainable futures. The session will feature experiences from cities such as Fortaleza, Lisbon, Chennai, Seoul, Tallinn, Bratislava, Bulawayo, La Paz, and Riyadh. As part of UN-Habitat’s Urban Circuit 2025, the event celebrates World Cities Day, valuing the role of data, innovation, and collective intelligence.
