“…These questions are as relevant in Gauteng as they are in New York or Mumbai� Whilst professionals may long have thought of what is now called the Gauteng City-Region (GCR) as a unit (Mabin, 2013), do the people of Gauteng think of themselves as residents of a city-region of a dozen million or more? Since 1994, transitions to new provincial and metro forms of government have led to various wrangles, including over a city-region transport authority, the future of Rand Water, huge investment in and subsidy of the Gautrain, and the introduction of tolling on what had always been 'free' ways� By their nature, these significant public engagements have been controversial and have accordingly contributed to changes in approach� Yet such debates did not actually engage with the underlying conception and overall direction of the 'city-region', nor with the relationship of people to the whole and to its future� Such matters tend to remain in more arcane discussions among professionals and politicians� Internationally, there are 'tensions and uncertainties between the city-region as a concept and the experiences of local communities' (Brenner, 2004, p� 49)� Public participation in shaping the future of the GCR will not take place with any intensity in the absence of provocations that spark debate -and these might be intentionally designed to do so rather than occurring by accident� Conflict over governance in other city-regions has something to offer to thinking about the future of governance in Gauteng's city-region� To examine how wider debate, and perhaps direct engagement, at the scale of the city-region can come about, this Provocation explores one powerful example of how public recognition of the unity of a large city-region, and public debate about the conditions and future of that region, have been provoked over the past decade or more� Recent debate across the city-region of Paris and its surrounds 2 contrasts strikingly with the earlier, more technical contests among professionals and sometimes politicians� By exploring the 1 'City-regions' receive much attention in various literatures -for their polycentricity and complexity (Gugler, 2004;Mabin, 2005;Scott, 2001); their diversity (Jones et al, 2015;Sharpe, 1995); conflicts over the scale of authority (Hamel & Poitras, 2004;Hamilton, 2012;Keil et al, 2009); and research approaches (Booth & Jouve, 2005;Kübler, 2012;Lefevre et al, 2013;Mould, 2016;Phares, 2004;Storper, 2013). 2 The terms 'Greater Paris', 'Grand Paris', 'metropolitan Paris', 'Paris region', etc.…”
