The city must belong to its citizens and inhabitants! This sentence concluded the conference “Social City: Aspiration of an Urban Transformation in Asia” held on 21–22 November 2017 in Jakarta. The conference was jointly organized by the RUJAK Center for Urban Studies, the Coordinating Ministry for Human Development and Culture of Indonesia (Kemenko PMK), and Friedrich-Ebert-Stiftung (FES) as part of FES’s Economy of Tomorrow (EoT) program. In the conference, various experts, including urban planners, grassroots activists, and government officials discussed the Social City concept, which is the central focus of this chapter, in relation to affordable housing, public transportation, and citizen participation. The discussions at the conference, followed by field visits in Jakarta, illustrated panelists’ and participants’ interpretations and practices they attributed to the Social City concept. This chapter examines the ideas, flow of discussions, and case studies observed in the conference by connecting them to existing academic literature and by contextualizing them to regional and global urbanization trajectories. The conclusion provides a critical perspective on the three takeaway points from the conference: 1) Social City is a holistic and collaborative urban development concept that champions affordable housing, mobility, and civic participation, but its emphasis on infrastructure is both a potential and a challenge; 2) Social City negates any social and cultural segregation, yet the implementation may face obstacles from powerful political and economic actors; and 3) Social City encourages citizens and residents to re-engage in the governance of urban development, which is the antithesis of exclusive and semi-authoritarian hegemonic urban visions.
