Economic development, decoupling and urban infrastructure : the role of innovation for an urban transition in Cape Town

[摘要] ENGLISH ABSTRACT: This thesis investigates the case of the Cape Town Central City Provincial Government Revitalisation Initiative (CCPGRI) as a means to further understanding of socio-technical transitions. The departure point for this research is the recognition that the current economic growth and development trajectory is unsustainable. Despite this, deeply institutionalised frames of reference for decision-making reinforce and perpetuate the utilisation of (incumbent) sociotechnical systems which diminish finite resources and deteriorate eco-system services. The theoretical notion of decoupling, however, offers an alternative economic development paradigm. Decoupling has been identified, within this thesis, as the guiding framework through which adaption strategies should be carried out. This was indentified through a comprehensive literature review and an assessment of Cape Town's critical networked infrastructure. Networked infrastructure conveys flows of resources across vast urban spaces, in a linear configuration, thus conditioning resource flows and consumption. The case of Cape Town, however, illustrates that a linear configuration of infrastructure is both financially and environmentally unsustainable. Moreover, the case provides the empirical evidence for decoupling, reinforcing the argument for the adoption of the notion as an alternative development paradigm. Networked infrastructure has furthermore been identified as a socio-technical system, and therefore is considered as the component requiring a system transition and the subsequent intervention point for decoupling economic growth from resource consumption. From an implementation perspective, socio-technical system transitions, achieved through innovation, are the necessary component for realising sustainable urban development. It is argued that innovation, necessary for socio-technical system transitions, should be the product of sustainability-orientated innovation systems (SOIS's). SOIS's are implicitly linked to decoupling through the shared goal of enabling greater sustainability. The Cape Town CCPGRI has been extrapolated onto the multi-levelled perspective (MLP) model and is used to further understanding about how socio-technical system transitionsare achieved. Findings indicate that socio-technical systems transitions are possible in urban areas that have multiple niche innovations developing simultaneously. Of significance is the presence of an intermediary, who is able to facilitate and manage the development of niche innovations emerging from SOIS's. It is therefore argued that high quality networking is critical for achieving socio-technical transitions which emerge from SOIS's.
