Gentrification on the planetary urban frontier: The evolution of Turner's noosphere

摘要

As capitalist urbanisation evolves, so too does gentrification. Theories and experiences that have anchored the reference points of gentrification in the Global North for half a century are now rapidly evolving into more cosmopolitan, dynamic world urban systems of variegated gentrifications. These trends seem to promise a long-overdue postcolonial provincialisation of the entrenched Global North bias of urban theory. Yet there is a jarring paradox between the material realities of some of the largest non-military urban displacements in human history in the Global South, alongside a growing reluctance to impose' Northern languages, theories and politics of gentrification to understand these processes. In this paper, I negotiate this paradox through an engagement of several seemingly unrelated empirical trends and theoretical debates in urban studies and gentrification. My central argument is that interdependent yet partially autonomous developments in urban entrepreneurialism and transnational markets in labour, real estate and education are transcending the dichotomy between gentrification in cities (the traditional focus of so much place-based research) versus gentrification as a dimension of planetary urbanisation. Amidst the planetary technological transformations now celebrated as cognitive capitalism' and a communications-consciousness noosphere', these developments are coalescing into a global, cosmopolitan and multicultural tapestry of explicitly evolutionary class transformations of urban space that adapt to multiply scaled contingencies of urban history, socio-cultural difference, state power and terrains of resistance. The argument proceeds in three steps. First, I explain how social Darwinism was deeply embedded within conventional urban theory in the decades before Ruth Glass gave us a language for the discussion of gentrification, thus perpetuating debates over narrow empirical issues at the expense of deeper critical scrutiny of the evolutionary logics of socio-spatial classifications. Second, I examine the recent movement for a cosmopolitan decolonisation' of gentrification theory that has emerged at the precise moment when powerful alliances are consolidating the networked infrastructures of gentrification on an unprecedented scale. Third, I analyse the contemporary evolution of gentrification as a recombinant blend of old and new, as the means of class transformation of urban space are accelerated through intensified competition in work, education and housing. The built environments of planetary urbanisation provide ample opportunities not only for diverse cosmopolitan descendants of old-fashioned urban renewal in the style of Haussmann's Paris or Moses' New York, but also for new generations of capitalists with conscience'-entrepreneurial coalitions closing moral rent gaps' by integrating the economic profits of gentrification with the discourses and practices of environmental sustainability, socially responsible development and global fields of educational opportunity. All of these escalating competitions are legitimated as inclusive multicultural meritocracies. Yet the relentless optimism of competitive innovation in the cognitive-capitalist noosphere is creating dangerous new frontiers of human ecology that reproduce the social-Darwinist form of society' that Frederick Jackson Turner envisioned in his theorisation of the recurrence of the process of evolution' in America's colonial-settler waves of violent dispossession.
