Introduction Today, half of the world’s population lives in cities. Cities today present humanity with enormous challenges and opportunities. While they are sometimes seen as dystopian, they are also the places where utopian ideas are reflected and implemented (see Bunnell 2004). Cities today are at the centre of the world’s economy. They are the motors of regional, national and global economies (Scott 2001). While global cities have been accorded the command and control centres of global finance and services (see Sassen 1994), major cities around the world have been rescaled due to the contemporary processes of globalization (Brenner 1998, 1999a, 1999b), but such rescaling need not be always at the cost of nation-states (Bunnell 2002). While scholars such Kenichi Ohmae (1995) argue that rescaled city-regions have emerged with a significant reduction in the role of national government, Brenner (1998) advocates this as a strategy adopted by national governments to encourage the rescaling of cities and city-regions. Cities are thus becoming central to the project of globalization (see Massey 2000).
