  • Gentrification in South Africa’s inner cities: Dignity takings
           requires restoration

    • Authors: Geci Karuri-Sebina, Frederick Beckley
      Pages: 4 - 17
      Abstract: Urban development in South Africa has generally sustained and reproduced spatially unequal and exclusionary trends and outcomes particularly for the  majority of the poor non-White populace. This article re-examines the urban redevelopment processes and ecosystems of South Africa to identify why  this might be the case. Atuahene’s ‘dignity’ concept and framework is adopted for this inquiry. Her framework posits the combination of systematic  property deprivation, dehumanisation and infantilisation of poor non-White South Africans as evidence to theorise that the urban land situation in post- apartheid South Africa constitutes ‘dignity takings’ (DT) and demands a ‘dignity restoration’ (DR) response. This article explores the applicability and  usefulness of this DT/DR framework in advancing more spatially just and inclusive frameworks and futures for South Africa. It does this by applying the  framework to the dynamics of urban socio-spatial change in post-apartheid South Africa, with a focus on the phenomenon of gentrification and its  exclusionary effects in four urban case vignettes. The lived experiences of these cases are used to demonstrate that there are both material and non- material aspects to unjust urban development, and that both types of deprivation require attention. The article proposes that gentrification can be  viewed as ‘dignity takings’, as it strips residents of their sense of place, ownership, and access to a better quality of life. It is thus argued that policymakers  could consider the DR/DT framework as an urban development lens through which to understand the unsuccessful attempts to merely  accept, resettle, or compensate displaced residents, proposing DR as a means to fully redress – rather than reproduce – the injustices of the past. The  DR/DT framework could contribute towards achieving South Africa’s Integrated Urban Development Framework’s transformation goal of having  development policies and approaches that move towards systematic DR that includes spatial justice, sustainability, efficiency, resilience, and good  administration.

  • Examining liveability in the informal community of Kabawa, Nigeria

    • Authors: Ayodeji Obayomi, Ayobami Popoola, Samuel Medayese, Bolanle Wahab
      Pages: 18 - 33
      Abstract: This article examines the nature and causes of liveability challenges faced by the residents of Kabawa, an informal community south-east of Lokoja, the  capital of Kogi State, North-Central Nigeria, and points out solutions to the identified problems. Liveability concepts were adopted, while both primary  and secondary data were used. The research instruments used included a structured questionnaire, an observation checklist, and a housing facility  survey. A total of 180 household heads/ respondents were randomly selected for the study. The study establishes that the community exhibited slum  characteristics, including poor housing conditions, filthy environment, poor sanitation, indiscriminate waste disposal, and acute lack of basic infrastructure. Illiteracy, poverty, poor maintenance of the available facilities, and lack of participation in governance are common challenges reported by  residents. The study recommends improved planning and partnership between government and other community development stakeholders towards  achieving improved liveability through participatory, community-centred development and a financial framework.

  • Urban pressure on the Rietvlei Nature Reserve in Tshwane, South Africa: An
           application of the Greenspace Stress Model of Urban Impact

    • Authors: Anna de Jager
      Pages: 34 - 51
      Abstract: Despite the ecosystem services potentially provided by urban green spaces, there are concerns about the sustainability thereof. Therefore, the nexus  between development, conservation, and sense of place was explored from a geographical perspective. A Greenspace Stress Model of Urban Impact was  developed through a case study of the Rietvlei Nature Reserve in Tshwane, Gauteng province, South Africa. The position of an urban green space within  two rapidly expanding cities was evaluated through a case study. Methods included a literature study, an analysis of land-use changes on remote sensing  images, face-to-face interviews, and focus group interviews. Findings from this research include that urban growth leads to increasing human needs and  expectations regarding the ecological services provided by green spaces. Stressors within the reserve include the water quality, the presence of invasive  species, development pressures intensified by the location relative to spatial development corridors and administrative boundaries, and insufficient environmental awareness. Successful local strategies support the idea that green space should be fit for purpose and meet the expectations justifying its  existence. Global environmental concerns should be considered in urban planning frameworks and in management of local spaces that people know and  care about. The physical characteristics and functions of an urban green space as well as the environmental perception and sense-of-place  evaluations of different stakeholders are important in decision-making about, and sustainability of ecosystem services.

  • A review of some of the criteria used in landdemarcation processes

    • Authors: Zaakirah Jeeva, Juanee Cilliers, Trynos Gumbo
      Pages: 52 - 61
      Abstract: In recent years, settlements have sprawled beyond the urban growth boundaries, due to a number of factors, including mobility, technology, and urban  blight. As a result, governments globally have opted to restructure their local administrative boundaries (municipalities) to be more accommodating to  the unplanned growth, while setting a clear limit to the extent to which the urban region could grow. Without a clear administrative boundary, urban  problems such as civil conflict, administrative duplication, political corruption, lack of service delivery, and environmental degradation become more  prevalent. In order to understand the driving forces behind administrative delimitation, this article reviews how local administrative boundaries can be  delineated from a theoretical stance. It further unpacks various criteria to contextualise how boundaries could be demarcated and their resultant  structure. The article reveals that, from a theoretical stance, the method of demarcating administrative urban boundaries is not apparent, since a variety  of factors influence open systems. Consequently, this article provides awareness of the challenges of demarcating local administrative boundaries, with  both administrative and policy implications. Administratively, it sheds light on criteria that can influence boundary demarcation. In terms of policy, it  demonstrates that the demarcation of boundaries is a huge challenge that requires further research and action.

  • Conformity to zoned urban green spaces in physical development plans: A
           spatiotemporal analysis of Kisii Town, Kenya

    • Authors: Wilfred Omollo
      Pages: 62 - 80
      Abstract: Although evidence assessing the provision of urban green spaces (UGS) corroborates their decline, they have, however, not evaluated conformity to  zoned UGS in physical development plans (PDPs). To fill the gap, this article examines conformity to zoned UGS in PDPs. It also investigates the drivers of  the observed non-conformities. Anchored in the theory of regulatory compliance, the study was undertaken in Kisii Town, Kenya, as a case study of the  zoned UGS in the Kisii Town Physical Development Plan (KTPDP). The population comprised a list of 367 developers occupying the zoned UGS, out of  which a sample of 186 was randomly selected. Spatial and descriptive data were respectively collected using satellite images and questionnaires. The  analysis relied on GIS, descriptive and inferential statistics. Results showed that 75 hectares (ha) of zoned UGS declined by 52% between 2005 and 2022,  resulting in a low per capita UGS of 1.95 m2 against the recommended 9 m2 . These changes were caused by developing without permits, the County  Government of Kisii (CGOK) granting permits to non-applicants, as well as approving developments without the mandatory change or extension of use,  insufficient monitoring of developments, laxity in enforcing zoning regulations, and uncertainty in the engagement of registered architects during the  development control process. Recommendations are made for a revised physical development plan covering the entire town to provide adequate UGS,  ensuring that building plans are submitted by authorised professionals and regular surveillance audits to deter unauthorised developments. The article  concludes that, in the absence of effective development control, UGS in Kisii Town will further decline, resulting in the residents not enjoying their  acknowledged benefits.

  • Differential urbanisation for settlement planning – A Western Cape
           case study

    • Authors: Peter Magni, Mari Smith Mari Smith, Helena Jacobs, Natasha Murray
      Pages: 81 - 97
      Abstract: The differential urbanisation model is a means to assess settlement growth rates. While the model has been tested primarily at a national level, including  in South Africa, this study seeks to apply the analysis to the sub-national scale in the Western Cape province and Cape Winelands district municipality. The  study found that the model is applicable to both the province and the district municipality. Settlements of differing size and economic importance  grew at varying rates relative to each other in a predictable sequence, which realised the urban hierarchy, over a 20-year period. This finding was  unexpected, given that the urban differential model assumes economic growth as well as labour and socio-economic homogeneity – factors that have  not been realised evenly sub-nationally. The applicability of the model to these locations may assist in the public division of resources, particularly in  small towns, where meaningful urbanisation occurs, yet capital allocations are limited. The applicability of the study is in keeping with national, provincial,  and municipal trends in planning that emphasise the interrelationship between settlements of different size and function over time, and the  importance of spatial planning in guiding public infrastructure expenditure.

  • Analysing the spatial pattern of road networks in Kimberley, South Africa

    • Authors: Tabaro Kabanda
      Pages: 98 - 109
      Abstract: The increasing burden on South African road networks necessitates sustainable solutions that conclude their spatial configuration and arrangement. A  deeper understanding of the existing road network’s spatial organisation is, therefore, required. This study evaluates the structural design of road  networks in Kimberley, South Africa, using spatial network science and open-source OpenStreetMap data. Nonplanar-directed multigraphs for Kimberley  are constructed to analyse the structural and morphological characteristics of the network. The study area was evaluated with several network-analysis  methods such as completeness, degree of centrality, betweenness, closeness, and PageRank. The study found that Kimberley has a low degree of  centrality of 0.00111. This indicates that the road network should be less congested because there are fewer vulnerable spots. Because of the availability  of two-way streets, the total edge length in the Kimberley network is nearly double the total street length. There are 2.97 streets radiating from Kimberley nodes on average. This suggests that three-way intersections are prevalent in Kimberley. Centrality measures and analysing the effects in terms of  accessibility to the commerce and services of the city show how the legacy of racial segregation, poverty, and isolation from social and economic  opportunities impedes the places within Kimberley. Results from the study also indicate that the informal sections of Galeshewe are fine-grained in terms  of road network, while Kimberley CBD and nearby districts have coarse grain roads. This pattern contributes to the relative overall low average  street segment length (a proxy for block size) of 107 metres in Kimberley.

  • Estimation and Web-GIS geovisualisation of a suitable solid waste disposal
           site: Case study of New City, Harare

    • Authors: Diana Dahwa, Aldridge Mazhindu, Kudzai Chirenje
      Pages: 110 - 123
      Abstract: With the ever-increasing human population, there is a need to develop new urban settlements for human habitation. For these new settlements, it is  imperative to optimally site different land-use zones, including solid waste disposal sites. The aim of this article is to determine suitable sites for locating  a landfill in a new developed city in Zimbabwe around Mt. Hampden, named the New City. The New City will have various residential, commercial, and  industrial areas. This entails the need for a proper site selection of a landfill to reduce the negative social and environmental effects such as  contamination of water bodies and proliferation of diseases such as malaria. GIS and remote sensing were the major methods used in mapping the suitable areas. Multi-criteria evaluation and weighted overlay analysis methods were used in the landfill site selection process. Factors used for landfill  site selection were rivers, settlements, roads, protected areas, and soils. A suitability map was generated, showing five potential sites that are suitable for  landfill siting in the New City. Moderately suitable areas cover approximately 8%. A further 73% of the total land area in the study area is highly unsuitable  for siting a landfill. A real-time WebGIS monitoring interface was developed to monitor land use on the selected area, because the New City is  a new area under development. Using a Web-GIS interface makes data easily accessible to environment planners, ecologists, spatial land planners, and  other decision makers.
