77 academic papers, 96 sessions, and 71 plenary speakers, focusing on sustainable urban development, placemaking, and the urban challenges ahead. The series contributed to the New Urban Agenda, as well as the principles of the Charter of Public Space and the UN-Habitat Global Public Space Toolkit. The 2015 conference was also the first Urban Thinkers Campus, and key members served as consultants to the Secretary-General for Habitat III. Now the focus is on implementation, and the need to share practical knowledge and “research into action.”
