Planning in Cape Towns interstices: case studies of informal land occupations in Cape Town, South Africa

Participatory planning has been institutionalised through planning legislation in most Western-style democracies since the 1940s. Irrespective of the variability in how participation is conducted in different contexts, participation is regarded as desirable. That is, provided participation activities and processes do not flout laws or infringe the property rights of others in the manner that informal land occupations do. Often characterised as a problem, informal land (whereby land is defined broadly to include vacant and under-utilised buildings) occupations and, consequently, the numbers of autoconstructed and retrofitted housing have not only continued apace since 1994 in South Africa, they have intensified in scale, frequency, and level of organisation. The aim of this research is to develop a theoretical understanding of informal land occupations from the residents' (read occupiers') perspectives. These citizen-led place making practices, which have not yet been fully theorised in Southern planning literature, constitute the issue under study. Thus, the main research question is: What strategies and tactics are used by residents to claim and sustain urban spaces in Cape Town, South Africa? To answer this question, the research employed the case study and discourse analysis methods. The four cases for this research were located in Green Point, Woodstock, and Khayelitsha. Fourteen (14) semi-structured interviews and five (5) focus groups were conducted to gain the perspectives of a range of actors in the spatial planning and human settlements sectors, namely occupiers, professional planners working within local government and non-government organisations (NGOs), activists, elected local government officials, and bureaucrats within local and provincial government departments. Additional data in the form of government publications, namely policy documents, legislation, and transcripts of Parliamentary debates and Council meeting minutes to mention a few, as well as photographs, media statements and articles was also collected in the period between 2016 and 2022. This data was analysed through an iterative cycle of open, axial and selective coding. The findings indicate that residents claim spaces, namely land and building, that are perceived to be vacant or underutilised. These spaces, which whilst requiring the (re)construction of housing or retrofitting, are suitable for a range of land uses. These spaces are residual in nature, nonsynchronous, accommodate new or atypical performances, create uncertainty and new rules. These spaces are claimed through bold, bi-directional discursive and physical strategies and tactics. Occupations are initiated through mobilisation, which continues for the occupation's lifespan in order to re-mobilise existing residents and to mobilise (additional)support and resourcesfor the movement. Once the occupation is under way, autoconstruction, retrofitting, repair, and maintenance activities are undertaken. These activities, along with discursive strategies and performative repertoires, enable residents to sustain their claims. The findings also highlight that these processes occur in the city's interstices, with many of these spaces being left vacant or underutilised as a result of the city's growth. Within these spaces of possibility, residents' visionsforthe city are ineffectively realised. These visions are based on inherited imaginations that, in turn, are founded on both Western and African philosophical and theological currents. And, it is from this intellectual foundation that the radicality of informal land occupations emerges. On this intellectual foundation, residents strive to foster an African sense of self, re-affirm their humanity and dignity whilst highlighting alternative solutions for dealing with their current reality

Cities, Space and Power

The scholarly purpose of this manuscript is to provide a resource for academics and researchers looking into cities, space and power in emerging economies. It also takes into consideration the relationship between emerging economies and developing contexts, as well as the lessons that may be shared between them. This book presents a unique perspective and aims to highlight issues not addressed much in writing on the built environment. Based on substantiation and references to numerous other sources and authors, alternative theoretical frameworks for the study of the built environment are developed. This is a very relevant contribution at this time, especially as cities will most probably go through transformations in the post-COVID-19 era. Our first line of defense against this public health crisis will be in areas of poverty, with people who have generally been excluded and urban practices that have been undocumented or labelled as informal. The main thesis of the manuscript is that space and power are strongly linked in cities. The research results prevalent in the book are original, and while the authors consult widely across disciplines, the themes are firmly rooted in the built environment fields – with a focus on the architectural discipline

Who has the right to remain in place? Informality, citizenship and belonging in Belo Horizonte, Brazil

The thesis looks at three conflicts related to the 2014 World Cup preparation in Belo Horizonte, Brazil. In each of the cases, affected groups – informal workers, informal residents and middle-class citizens – engage with the state to claim rights over space. It examines how the entanglements between social class and legal/institutional developments engendered through “peripheral urbanisation” shape the capacities of those groups to affect formal/informal boundaries and have their demands legitimated. This research draws on the findings from a fieldwork in Belo Horizonte, which lasted eight months in total between 2014 and 2016 and involved archival research, participant observation and semi-structured interviews with relevant actors. Three cases are considered, which include: the Mineirão stadium redevelopment that displaced a group of informal workers while creating a conflict in a middle-class neighbourhood; the demolition of an informal settlement to make way for a transport infrastructure project; the construction of a hotel in a middle-class area against the will of local residents. The thesis presents three key findings. Firstly, the urban space production is affected by citizens’ capacity to engage with the state. While the state-society boundaries are blurry, citizens are unevenly empowered to have their demands validated and avoid displacement, i.e. the loss of place. Secondly, while informal residents have their rights partially recognised thanks to the “insurgent citizenship” struggles of the past, informal workers are not entitled to compensation because of the disassociation of work informality debates from spatial considerations. Finally, middle-class politics matter, as middle-class residents are better equipped to validate their claims and protect their place in the city. The research contributes to recent postcolonial debates on urban space production and informality. I show that both informal working and housing practices are interconnected through the place-making strategies of the urban poor as well as of the urban middle-class, all of which generate important implications for the reproduction of socio-spatial segregation and thinking of the Brazilian urban future

African Luxury

Moving far beyond predominant views of Africa as a place to be 'saved', and even more recent celebratory formulations of it as 'rising', African Luxury: Aesthetics and Politics highlights and critically interrogates the visual and material cultures of lavish and luxurious consumption already present on the continent. Methodologically, conceptually and analytically, the collection dismantles taken-for-granted ideas that the West is the source and focus of high-end and hyper-desirable material cultures. It explores what the culture of consumption means in Africa in both historical and contemporary contexts, studying diverse luxury phenomena including fashion advertising, reality television, retail, gendered consumption and gardening to re-centre the discussion on existing contemporary luxury cultures across the continent

Morphological themes of informal housing in Colonias: impacts of sociocultural identity on Webb County housing form

Informal settlements are a form of housing found in many parts of the world. Self-help housing in informal settlements has different influences that are denoted in the customs and preferences of the residents, which in turn, are reflected on the elements of house exteriors as well as its interior. Colonias in the U.S-Mexico border region are a model of informal settlements. The purpose of this study is to analyze the social and cultural influences on housing fronts in Webb County Colonias. The study focuses on investigating traditional features, vernacular forms, building rituals, and social features as they relate to the morphology of house fronts and their production. The housing model of Geddes and Bertalanffy explained by Turner (1972) was the premise of establishing the argument of this study. A mixed-method approach was used in data gathering from the following three Colonias: Los Altos, Larga Vista, and Rio Bravo. Utilized methods included image-based research through systematic random sampling of housing fronts in the Colonias, as well as a group-administered structured survey distributed during community monthly gathering for food distribution. The development of the research process and methodology incorporated the input of the local community and local leaders and volunteers assisted in its implementation. The study concluded that past and present experiences of Colonias residents have intense impacts on different aspects contributing to the themes comprising the morphology of Colonias housing fronts. A classical pattern of migration as well as maintained contact and continuous dialogue between residents and their kin were found to result in preserving the inherent native culture of the Coloniasâ residents and can thus be considered as core elements. This preservation of native culture was indicated by utilization of semi-private space, traditional roof forms, privacy and security elements, and building rituals. The study also identified additional secondary modified elements, represented by the lack of gates utilization as a measure of security. These core and modified elements coincide with the Geddes and Bertalanffy model and therefore it can be deduced that this model can be applied in the case of the Colonias

Evolving comprehensible and scalable solvers using CGP for solving some real-world inspired problems

My original contribution to knowledge is the application of Cartesian Genetic Programming to design some scalable and human-understandable metaheuristics automatically; those find some suitable solutions for real-world NP-hard and discrete problems. This technique is thought to possess the ability to raise the generality of a problem-solving process, allowing some supervised machine learning tasks and being able to evolve non-deterministic algorithms. \\ Two extensions of Cartesian Genetic Programming are presented. Iterative My original contribution to knowledge is the application of Cartesian Genetic Programming to design some scalable and human-understandable metaheuristics automatically; those find some suitable solutions for real-world NP-hard and discrete problems. This technique is thought to possess the ability to raise the generality of a problem-solving process, allowing some supervised machine learning tasks and being able to evolve non-deterministic algorithms. \\ Two extensions of Cartesian Genetic Programming are presented. Iterative Cartesian Genetic Programming can encode loops and nested loop with their termination criteria, making susceptible to evolutionary modification the whole programming construct. This newly developed extension and its application to metaheuristics are demonstrated to discover effective solvers for NP-hard and discrete problems. This thesis also extends Cartesian Genetic Programming and Iterative Cartesian Genetic Programming to adapt a hyper-heuristic reproductive operator at the same time of exploring the automatic design space. It is demonstrated the exploration of an automated design space can be improved when specific types of active and non-active genes are mutated. \\ A series of rigorous empirical investigations demonstrate that lowering the comprehension barrier of automatically designed algorithms can help communicating and identifying an effective and ineffective pattern of primitives. The complete evolution of loops and nested loops without imposing a hard limit on the number of recursive calls is shown to broaden the automatic design space. Finally, it is argued the capability of a learning objective function to assess the scalable potential of a generated algorithm can be beneficial to a generative hyper-heuristic

The 'Casas GEO' movement: an ethnography of a new housing experience in Cuernavaca, Mexico

Through an ethnographic approach, this thesis looks at a new housing form and what is claimed to be a new urban way of life in Mexico’s neoliberal era. The study looks in detail at residents of a single housing project in Cuernavaca, Mexico, and explores how this group has struggled to construct itself as a new cultural category or what I call the Casas GEO movement. The research is guided by a series of questions: why and how did the Casas GEO movement emerge; how do residents experience a new housing project in everyday life; and, what meanings do they communicate through these everyday practices? Specifically, the research engages with recent literatures on new middle classes and approaches that consider ‘class’ as a process that grows out of cultural and “classificatory practices” (Bourdieu, 1984). The research builds on these literatures in a number of ways. First, it conceptualises the housing project as a mutable place, produced through daily interaction and a varied coexistence. Second, it understands the residential space as the arena for the emergence of a new cultural category created in everyday life through specific claims, values and symbols expressed in the urban landscape. The thesis shows how the developer, the GEO company, attempted to construct a set of individual values and codes of behaviour for residents, as an imperative to make the site liveable. But, it considers also how residents use their houses differently from the developers’ intentions through strategies of re-appropriation and personalisation in order to communicate ideas of distinction and ‘good’ taste. Importantly, residents had to deal with a range of inconsistencies, flaws and drawbacks in the project’s realisation that challenged representations of the ‘good’ city, social progress and modernity. The research shows how these failings influence people’s lives, especially their aspirations and sense of identity. My claim is that in the making of the Casas GEO movement people negotiate a cultural formation and produce a new space that allows ways of imagining, aspiring to, and modes for taking part in a modern ‘urban’ life. Yet, the making of the movement also exposes the fragility of a housing project that claims to be the formula for upward mobility of lower-income groups in Mexico
