Item BRICS Cities: Facts & Analysis 2016(South African Cities Network, 2017) Harrison, Philip; Yang, YanBRICS Cities: Facts & Analysis is a compendium of research produced through a partnership between the South African Cities Network (SACN) and the South African Research Chair in Spatial Analysis and City Planning (SA&CP) in the School of Architecture and Planning at the University of the Witwatersrand. It presents key general and thematic descriptive and comparative information about urban growth and development in the five BRICS states: Brazil, Russia, India, China and South Africa. The comparative analysis includes a section relating to cities in Africa, while the detailed Factsheets cover thirty-one of the largest BRICS cities. BRICS Cities provides a first-of-its-kind research base to inform ongoing sub-national BRICS research and policy consideration. Recent reports on urbanization point out that over the next 20-30 years, almost all of the expected growth in the world population will be concentrated in the urban areas of the less developed countries of which a significant 42% will occur in cities in BRICS countries. Despite the fact that the distribution of the urbanization figures will be highly unequal between the different countries, considering the currently high levels of urbanization in Russia and Brazil and the extremely low levels (just over 35%) in India, the realities of large scale urbanization can and no doubt will have substantial impacts on the material conditions of urban life, governance, service provision, social relations and the environment. There has also been, and will continue to be, the expansion of networks of all kinds far beyond designated urban boundaries. In some cases, these challenges and the expanding boundaries have been met with additional layers of government, innovations in policy-making, and the reconfiguring of relationships between urban actors. However little is known in a comparative sense around some of the most important sites and cities in the BRICS countries , and insufficient research has been undertaken to learn from the differences that have been identified. The SACN and SA&CP, in line with our mutual interest around the nature and shape of urbanization and urban processes in South Africa and in BRICS countries, have developed a compendium of comparable information around key cities in the BRICS countries. BRICS Cities will serve as a useful reference of important base line information but also offers comment on the state of key areas of shared concern: innovation-driven economies, transport and mobility, and green energy. Furthermore, the publication provides a careful analysis of these factors in a comparative and relational framing.Item Johannesburg and its epidemics: Can we learn from history?(Gauteng City-Region Observatory, 2020-11-30) Harrison, PhilipCovid-19 has massively disrupted life globally and locally, bringing many uncertainties in its wake. It is not, however, the first epidemic to pummel the Gauteng City-Region. This GCRO Occasional Paper provides a detailed account of previous epidemics, including smallpox, the plague, influenza, measles, polio, scarlet fever and HIV/Aids. It asks whether we can learn from this history to benefit the present time. It shows that although we must use history judiciously because circumstances vary enormously across time, there are persisting themes and a knowledge of history can help direct attention to critical concerns. These themes are addressed in the report and include: the uncertain and idiosyncratic course of epidemics; social fault-lines exposed through epidemics, worsened through scapegoating, stigmatising and pathologising; the effects on livelihoods and the economy; the impacts on spatial form and infrastructures; the ways in which governance impacts the course of epidemics; and the ways in which epidemics influence the continued evolution of governance.Item Resilient Densification: Four Studies from Johannesburg(South African Research Chair in Spatial Analysis and City Planning; Gauteng City Region Observatory, 2015) Todes, Alison; Harrison, Philip; Weakley, DylanUnlike most cities in the world, over the last 20 years Johannesburg has become more dense and more compact. This reflects the increased rates of rural-urban migration from the late 1980s as urbanisation controls collapsed, but also the relative success of Johannesburg’s economy and democratic-era policies to contain urban sprawl (such as the urban development boundary). The ending of apartheid regulations allowed a release in a pent-up demand for access to large cities with much of the movement directed to the three large metropolitan cities in Gauteng. Densification in the city has occurred in both planned and unplanned ways. In line with directions in planning internationally, post-apartheid planning has placed strong emphasis on urban densification and compaction. At the same time, however, market forces (both formal and informal) have driven densification in the city, in ways that are often unforeseen and sometimes contrary to city policies. In order to plan for further development and to respond effectively to the densification that has happened, and is occurring, research into the processes and effects of densification is clearly needed. In this work we use an “urban resilience lens” to investigate four forms of residential densification in Johannesburg, using four illustrative case-studies. We explore the effects that densification is having in the city, showing how diverse, complex and contingent it often is.Item SPATIAL FUTURES: ASPIRATIONS AND ACTIONS REGARDING FORM AND SPATIAL CHANGE IN JOHANNESBURG(2016-06) Todes, Alison; Charlton, Sarah; Rubin, Margot; Appelbaum, Alexandra; Harrison, PhilipAddressing the racially divided, sprawling and socially inequitable spatial form of South African cities has been key to strategic spatial planning and urban spatial frameworks in South African cities, including in Johannesburg. These ideas were included in the Johannesburg 2006 Growth and Development Strategy (GDS), and in the 2011 GDS, which focused more strongly on resilience, but making strong links to spatial form. They have also been a consistent element of various rounds of Johannesburg Spatial Development Frameworks (SDFs). However, despite several of these concerns being embodied in national urban and city policies, objectives to restructure cities spatially have proven to be very difficult to achieve, and there is a growing frustration and questioning of whether some of these objectives are still appropriate. At the same time, the urban restructuring agenda, and the areas that spatial policy addresses have been constrained in practice, and there are several gaps and silences in the issues that are addressed. This paper provides a discussion of the choices, tensions, and trade-offs facing spatial policy in Johannesburg. It considers whether the policy objectives expressed in existing spatial policies (including the Johannesburg GDS and SDF) are still relevant, and address key spatial dynamics and issues. It does this by exploring several key areas of debate around the spatial form of cities and spatial policy internationally, examining how they manifest in Johannesburg, and highlighting these choices, tensions and trade-offs. It recognises, as a starting point, that while urban spatial policies have some power to shape spatial change, spatial trends and dynamics occur in a complex environment, where there are many drivers and shapers of spatial change. As emphasised in the position paper on ‘Strategic Planning in a Turbulent and Uncertain Context’, spatial policies that hope to influence spatial change need to understand the (shifting) key trends and drivers that affect space, including demographic, economic and social patterns that influence the demand for space. There are many examples of spatial plans which missed key trends, vastly over- or under- estimated population growth, and consequently planned for spatial forms which proved to be inappropriate. The spatial form of cities is also shaped by markets of various forms. Planning may attempt to engage with and regulate or direct these markets in the interests of its social and spatial goals and objectives, but it does not have completely free reign. Further, there are frequently disjunctures between strategic spatial planning and implementation, reflecting limits in terms of capacity, political will, institutional cooperation/integration and other factors. Finally, city spatial policies do not occur in isolation, nor do spatial policies necessarily have the power desired by planners. Spatial change and spatial form is critically affected by infrastructural investments, particularly in relation to transport (roads, transit systems), which are frequently follow a different planning process and logic (UN-Habitat, 2009). Likewise, differences between spheres of government and sectoral departments with power to invest in the built environment are also key to the disjunctures between spatial plans and outcomes. The emphasis on housing delivery on scale, along with cheaper land on the periphery, has undermined spatial policies towards urban compaction both internationally (Buckley et al., 2016) and in South Africa (Charlton, 2014). The recent international emphasis on ‘mega- projects’ is often driven by the private sector (such as major gated estates), but also by parts of the public sector (for example eThekwini’s airport). It is also influencing spatial change, bypassing spatial plans or forcing their adaptation (Shatkin, 2008; Robbins et al, 2015; Todes, 2014). This paper explores several key points of focus and debate affecting the spatial futures of cities, particularly in relation to Johannesburg. It draws out the key choices, tensions and trade-offs in these areas, and their implications for future spatial planning in Johannesburg. These include: • The debate over the creation of a more compact urban form, versus expanding and sprawling cities, including the discussion of new cities and satellite cities. Sustainability and resilience as key discourses and their implications for urban spatial form, and the role of transport and mobility will be considered in this context. Understandings of densification, how it is encouraged and managed will also be discussed. • Trends towards social exclusion versus arguments for spatial justice and the right to the city. This discussion considers trends towards privatised and splintered urbanism, gated communities, gentrification, and safety and security as a driver. It also discusses other dimensions of exclusion/inclusion—race, gender and the question of migrant spaces, and policies on socio-spatial integration. • Processes of spatial change in poor neighbourhoods, and initiatives to improve conditions there, including upgrading informal settlements, the growth of informal trade, addressing backyard housing. • Relationships between space and economic development, including the dynamics of growth and decline across the city, debates over promoting development on the periphery versus existing areas of agglomeration, and initiatives to promote economic development in townships. • City-region and multi-scalar governance, including the extent to which metropolitan governance addresses competing tensions and interests across the city, cross-border issues, and disjunctures and tensions between spheres of government.Item Strategic Planning in a Turbulent and Uncertain Context`(2016-08) Harrison, Philip; Appelbaum, Alexandra; Charlton, Sarah; Rubin, Margot; Todes, AlisonUncertainty and turbulence is a perennial feature of the context within which cities must plan but there are time periods in which a sense of uncertainty is heightened. This has been the case in the period since the Global Financial Crisis of 2007/08 where the experience of uncertainty has reached levels not known since the Great Depression of the 1930s. The Financial Crisis was an ‘uncertainty shock’ but it has left tremors in its aftermath. As one commentator put it, the recovery from the crisis has been “anaemic, brittle and fraught with uncertainty” (Tyson 2015). The combination of economic uncertainty in the contemporary period with political turbulence, global terrorism, and anxieties over climate change has created a ‘perfect storm’ of uncertainty. Wiltbank et al. (2006) write that “unknowability (true unpredictability) can be a disquieting and disruptive phenomenon.” This is especially so for the activity we call ‘planning’ which, almost by definition, requires some degree of confidence in our expectations for the future. The legitimacy of planning depends on the extent to which is can handle radical uncertainty. While the more traditional forms of planning may be helpless in the face of this uncertainty, there are, fortunately, approaches to planning within contexts of uncertainty that have evolved in both corporate and public sector planning practice since at least the late 1960s. In this paper we begin by outlining some of the dimensions of uncertainty, both globally and for the context of Johannesburg, focussing on aspects relating to demography, environmental threats, economy, society and politics, acknowledging, of course, that these are all profoundly interrelated. We then explore the multifaceted literature on planning for uncertainty, using the framework provided by Wiltbank et al. (2006) which distinguishes between approaches which are concerned with the better positioning of an institution within an uncertain environment, and those which actively attempt to shape environments. We apply the useful elements of the varying approaches to a brief analysis of Johannesburg’s current Growth and Development Strategy (GDS) exploring the extent to which the GDS has successfully accommodated uncertainty. We conclude with recommendations on how a new or revised GDS may better respond to uncertainty. Our approach to this study is broadly informed by a key insight offered by Peter Drucker in his seminal piece, ‘Planning for Uncertainty’ published in The Wall Street Journal in 1992. Drucker asked the question “What must we do––in fact, what must we become––if we are to successfully navigate the treacherous waters of unpredictability?” He argues, with reference to corporate planning but with relevance to public sector planning, that traditional approaches to dealing with uncertainty are not helpful: Uncertainty––in the economy, society, politics––has become so great as to render futile, if not counterproductive, the kind of planning most companies still practice: forecasting based on probabilities. (Drucker 1992) Drucker suggests an alternative approach to thinking about the future. Instead of asking “what is most likely to happen?" planning for uncertainty asks, instead, “what has already happened that will create the future?” This is the approach we take below in outlining dimensions of uncertainty. Our analysis is not futuristic and speculative but rather asks what the existing or emergent trends, and identified risks, are and what this may mean for the future. The reality, of course, is that the future is thoroughly unpredictable and we can only present these dimensions as illustrative of the scope of uncertainty and not as the basis of any form of projection. More important, appreciating these sorts of uncertainties, is how we can proceed with non-predictive forms of planning. A critical question that will address further in the text is whether our planning should focus only on adapting to uncertainty, or whether it should actively seek to shape the nature of the uncertainty. We do not assume that uncertainty is necessarily negative. In the corporate literature, at least, there is a strong recognition that uncertainty brings opportunity. This is arguably also the case in planning for the future of large and complex cities. Kaplan (2008) writes that, with uncertainty “often the basic meaning of a situation is up for grabs”. With uncertainty comes the opportunity to rewrite scripts in more desirable ways. However, there are massive risks if trends are misread or ignored.Item The persistence and rise of master planning in urban Africa: transnational circuits and local ambitions(Informa UK Limited, trading as Taylor & Francis Group, 2022-03-27) Harrison, Philip; Croese, SylviaMaster plans have long been criticized by critical planners who have argued in favour of more strategic, collaborative and relational forms of spatial planning that can more adequately respond to local needs and realities, especially in the context of the global South. Rather than critiquing master planning, this paper seeks to interrogate its recent rise in urban Africa. Building on a review of international planning trajectories, the paper seeks to challenge dominant narratives in the Western literature around the rise and decline of master planning. Planning experiences from across the African continent illustrate how master planning was a limited practice under colonialism and emerged more strongly in early post-colonial years, while persisting through a quiet period of planning and proliferating in recent times. By exploring the diversity in the influences and approaches to master planning for new and existing cities in Africa over time, the paper positions master planning as the product of a complex array of transnational circuits and multiple local actors and ambitions which intersect across different scales. The study of master planning should therefore be considered as an important entry point into understanding and rethinking the contemporary politics of urban planning, implementation, and development in Africa.Item Uneven spaces: core and periphery in the Gauteng City-Region(2017-08) Peberdy, Sally; Harrison, Philip; Dinath, YasmeenPeripheral areas of the Gauteng City-Region – like small towns on the edge, large peri-urban and commercial farming areas, sprawling dormitory townships, huge swathes of displaced urbanisation in ex-Bantustans, and remote industrial and mining areas – are all poorly understood. Yet there is evidence that many of these areas are undergoing rapid change, with profound implications for many current policy debates including what to do about inequitable economic growth patterns, how to manage ongoing population movements in the post-apartheid period, where best to locate large public housing schemes, and so on. Uneven spaces: Core and periphery in the Gauteng City-Region, GCRO’s sixth research report, comes from a clear recognition that despite the comparative wealth of Gauteng and its role in driving the national economy there are places of relative ‘peripherality’ in the GCR that require attention. The report is also a response to a strong focus in the existing literature on the physical and economic core of the province, the City of Johannesburg in particular. By contrast there is a relative paucity of analysis on less central parts of the city-region. The work is the result of a research partnership between the GCRO and the South African Research Chair in Spatial Analysis and City Planning (SA&CP), in the School of Architecture and Planning at Wits University. GCRO’s Dr Sally Peberdy wrote the first part of the report entitled ‘Uneven development – core and periphery in Gauteng’. Prof Philip Harrison and Yasmeen Dinath from SA&CP compiled the second part, ‘Gauteng – on the edge’. Both parts, albeit through different modes, consider transitions in the social- and space-economies of outlying places. The first part investigates the dynamics of peripheral areas in Gauteng through the lens of theories of uneven development. Showcasing a wealth of data and maps generated from the Census and GCRO’s own Quality of Life surveys, it analyses the multiple ways that spaces may be peripheral. These include unequal access to housing and services; the spread of income, household assets and employment opportunities; variations in perceived quality of life; and so on. The analysis builds from an initial binary delineation of parts of Gauteng as either ‘core’ or ‘periphery. It then progressively nuances our understanding by showing that notions of core and periphery are relational, that processes of change across what may be counted as core or periphery are often indeterminate and contradictory, and that there are often ‘peripheral’ areas in the heart of the GCR, and ‘core’ features in areas conventionally regarded as on the margin. This section concludes with thoughts on the role of government in creating, sustaining and ameliorating multiple forms of peripherality, The second part of the report asks the question ‘what is happening along the geographic edge of the GCR?’, and seeks to answer this both through the lens of scholarship on edge cities, peri-metropolitan areas, and agglomeration, as well as through a number of in-depth case studies in six types of peripheral areas: 1. Areas with extractive economies (Carletonville); 2. Industrialising ex-mining areas (Nigel-Heidelberg); 3. Areas with state-implanted industry (The Vaal, including Vereeniging, Vanderbijlpark and Sasolburg); 4. Decentralised growth points (Babelegi); 5. Agricultural service centres (Bronkhorstspruit); and 6, Recreational hubs (Hartbeespoort). Through its exhaustive narrative accounts of the development of specific places on the edge of the GCR, this section of the report compellingly highlights the importance of history and timing, and asks us to consider how urban development drives economic development and vice versa. Although ‘core’ and ‘periphery’ are artificial constructs, these terms gesture at very real spaces of uneven growth and development. The two parts of this report, different but complementary, considerably deepen our understanding of what is going on in parts of the city-region that are less well researched, and help focus the attention of policy-makers concerned with the causes and effects of – as well as possible solutions to – spatially uneven development outcomes.Item Urban Resilience Thinking for Municipalities(University of the Witwatersrand, Gauteng City-Region Observatory, 2014) Harrison, Philip; Bobbins, Kerry; Culwick, Christina; Humby, Tracy-Lynn; La Mantia, Costanza; Todes, Alison; Weakley, DylanThis document was prepared as a contribution to the Department of Science and Technology’s (DST’s) Grand Challenge on Global Change and as a complement to flagship initiatives such as the South African Risk and Vulnerability Atlas project (Archer, et al., 2010). The Global Change Grand Challenge is aimed at “supporting knowledge generation and technological innovation that will enable South Africa, Africa, and the world, to respond to global environmental change, including climate change” (Archer, et al., 2010, p. ii). While the Grand Challenge highlights the importance of science in supporting South Africa’s response to global change, it extends beyond a purely biophysical focus to acknowledge the importance of the social sciences. There is a clear understanding that the most compelling responses to global change will come through the combined efforts of the natural and social sciences. The DST therefore supports a number of research programmes across South Africa that draw on a wide range of scientific and academic fields in responding to specific challenges of global change across rural and urban –South Africa. One of the key thematic areas supported through the Grand Challenge is “urban resilience”. This is not at the expense of work on rural areas, as there are also a number of research programmes targeting rural South Africa, but it is recognition of both the threats posed by poorly managed urban areas and of the opportunities that towns and cities offer for greater resilience and sustainability.Item Urban Resilience Thinking for Municipalities(University of the Witwatersrand, Gauteng City Region Observatory., 2014) Harrison, Philip; Bobbins, Kerry; Culwick, Christina; Humby, Tracy-Lynn; La Mantia, Costanza; Todes, Alison; Weakley, DylanUrban resilience is the 'new kid on the block'. Over the past few years the concept has rapidly gained a central place in spatial and urban planning policy in South Africa........(This article)... is not designed as a 'manual' or 'tool box', but rather as a tool to promote urban resilience thinking.
