    An analysis of an urban edge as urban growth management instrument : Cape Town, South Africa

    ENGLISH ABSTRACT: The City of Cape Town (CoCT) has since the 1990s employed an urban edge line and development edges policy as growth management instruments in its spatial development framework (SDF) (CoCT 2011). However, in the most recent Cape Town Spatial Development Framework (CTSDF) of 2017 they no longer make use of an urban edge line or policy as an instrument to contain horizontal urban spatial growth. Instead, the latest CTSDF champions development that will support transit‐oriented development in the urban core and notes the city’s intention not to extend services towards the urban periphery in the short‐term (CoCT 2017). This sees a considerable turn‐around from the stated historic apprehension to persistent growth pressure to the northern and eastern urban extremities of the metropolitan area by using an urban edge, and seems to suggest that the former urban edge policy was considered inappropriate or problematic to the CoCTs objectives for spatial development in the latest SDF. Reasons for the termination of this policy‐approach formed the basis of this research in which, firstly, the spatial outcomes of the urban edge line and policy in Cape Town since 2001 was evaluated by using an urban sprawl index (USI); and secondly, the decision‐making processes associated with urban development proposals contravening the urban edge line and leading to the ultimate termination of the urban edge policy instrument were analysed by applying a five‐stream confluence model. The research results revealed disproportionate population growth compared to urban expansion over a comparable time period, suggesting that the urban edge line and policy, during its time of acting as an urban growth management instrument was successful. Evaluation of decision‐making processes revealed consistent poorly motivated political decisions contravening the urban edge line and development edges policy, in favour of a neoliberal growth agenda, thereby strongly suggesting a neoliberal capture of the decision‐making authority.

    The application of an Urban Sprawl Index : comparing towns and cities in the Western Cape Province, South Africa
    (CONSAS, 2018) Horn, Anele; Van Eeden, Amanda
    The incidence and effects of urban sprawl have been the subject of a great many academic research mainly as a result of the challenges posed by continued urbanisation, especially in developing countries (see inter alia Jenks, Kozak and Takkanon 2008; Mander, Brebbia and Tiezzi 2006; Jenks and Burgess 2000; and Soja 2000). South Africa witnessed a proliferation of legislation and spatial policies to limit urban sprawl and contain the physical expansion and development of urban areas during the last two decades in response to exponential post-apartheid urbanization. In 2005, the Provincial Spatial Development Framework of the Western Cape Province, South Africa stated that “an Urban Edge shall be drawn around all villages, towns and cities in the province with the primary function to contain outward growth of urban settlements” (City of Cape Town, 2009) and in parallel the Provincial Department of Environmental Affairs and Development Planning published the Western Cape Urban Edge Guideline document assisting all municipalities in the province to delineate urban edges to be included in municipal Spatial Development Frameworks (SDF) thereby illustrating intent on maintaining urban footprints that are compact and limit developments that could be considered urban sprawl. Subsequently municipal urban edges have been delineated and are presently reflected in most municipal Spatial Development Frameworks in the province. This paper presents an Urban Sprawl Index as a tool to comparatively analyse the extent of urban sprawl between cities and towns of different sizes, making use of cadastre, land use and population data over time. The Urban Sprawl Index (USI) for the Western Cape put forward by this research will enable the comparative measurement of the extent of urban sprawl proportionately between the Metropolitan and local municipalities in the province and thereby aid in understanding the impact of planning instruments such as urban edges in the context of development dynamics and pressures experienced by individual cities.
