will be used to explain the multiple and complex relations between actors, which elevate the achievements of particular policies and bring certain cities into conversation with one another, while pushing other ideas, policymakers and places further apart.
Chapter 3, “Translating BRT to South Africa”, traces the global geography of BRT to understand what features attracted South African policymakers and, in so doing, reflects on the theoretical notion of best practice policy models and their process of mobilization, mutation and translation. Moving away from the assumption that BRT is merely a technological template for stations and busways, this chapter reveals that the Bogotá model was not replicated in South African cities but rather that a variation, which focused on the transformation of the informal transit system, emerged. This suggests that policy models are polysemic, and rather than being duplicated they are modified and mutated to suit the needs of each importing jurisdiction. The adoption of best practice therefore takes place only when aspects of the circulating notion combine with underlying conditions, thereby normalizing the particular technical arrangements and social rationalities for adoption.
Chapter 4, “Actors and associations circulating BRT”, focuses on the urban planning professionals, practitioners and politicians introducing, circulating and managing the adoption of BRT. While some are instrumental in planting ideas that may lie dormant for some time, others engage in their prospective evaluation and actively stimulate their application. International policy actors cannot simultaneously create, impart, mobilize, and approve global policy models. Instead, it is the local (South African) policy actors that localize international best practice. Their interactions with internationals legitimize global policy by giving it both local and transnational salience. This examination of the policy actors expands our understanding of the varied direction, speed and influence of global and local influences shaping the contemporary city.
Chapter 5, “The local politics of BRT”, analyzes the international, national and local connections and disconnections between localities that influenced its adoption. At the international scale, this chapter reveals a deliberate preference to learn from Bogotá rather than a multiplicity of South American cities who also implemented BRT. This same enthusiasm for south–south exchanges was also used to disregard the experiences of African and Indian cities. Within South Africa, this chapter explores the competitive political and technical relationships between cities that influenced the adoption of BRT. This multi-scalar analysis of the politics of BRT explains the process by which policy and policy actors connect and disconnect topographically and topologically.
Chapter 6, “Repetitive processes of BRT”, situates BRT adoption within a longer history of South African transportation planning. It exposes previous involvements with BRT-like interventions that did not progress. This chapter contests the fast policy literature, which identifies the introduction of prefabricated best practice policies as part of the shortening of the policymaking cycles. Rather it suggests that there are multiple temporalities through which circulated policies emerge and remerge before adoption, and that often without these multiple attempts, policy circulation would not be effective. BRT learning is therefore gradual, repetitive and at times delayed.
Chapter 7, “Conclusion”, outlines the book’s main theoretical arguments, in particular answering how and why cities adopt circulated forms of knowledge. Here, I argue that policy mobilities is a process of learning and understanding, adoption and adaption, competition and collaboration, facilitated by local South African policy actors and their relations with urban elsewheres. In concluding, How Cities Learn explores the impact of BRT on the socio-spatial landscape of the South African city, and situates this study within the wider process of post-apartheid transformation.
Notes
1 1 Interviews 69 and 62.
2 2 Appendix A includes a list of interview respondents including their title, organizational affiliation, place and date of the interview. Appendix A is used throughout the book to link interview material with interviewees through a numerical system that lists the interviews chronologically. A number in brackets (e.g., [15]) refers to a particular interview and the reader should turn to Appendix A for supplemental information on that source.
3 3 Racial categories are a legacy of apartheid in which all South Africans were defined according to these four classifications. These terminologies continue today. I have included the racial categories of my interview respondents to inform the reader of the extreme disproportionality between those planning for transport and those using the transport.
Chapter Two Geographies of Knowledge
Building an Analytic for Tracing
The widespread adoption of BRT in South Africa denotes a process of “policy mobilities” in which localities create, circulate and adopt global innovation (McCann 2011b; McCann and Ward 2011). How Cities Learn reveals that policy mobilities is not only the “purposeful, repetitive, programmable sequence of exchange and interaction between physically disjointed positions held by social actors in the economic, political, and symbolic structures of society” (Castells 1996: 442), but also a process of dialogue and debate which involves power and personalities. These practices, however, have proven difficult to research since the exchanges rarely lead directly to uptake. Previous studies have traced the movement of knowledge through various “coordination tools” (McFarlane 2011b: 364), which include consultancies (Rapoport and Hult 2017; Wood 2019b), conferences (Cook and Ward 2012; Temenos 2016), study tours (Montero 2016; Ward 2011; Wood 2014a), technology (Rapoport 2015), and workshops (Wood 2014b); and others have followed the transnational advocacy groups (Stone 2002) and learning organizations (Wood 2019c) that package, frame and legitimize global circulation (Theodore and Peck 2011). Scholars tend to conclude that learning emerges through various voices, interests and expectations, translating and coordinating a multitude of information, including existing knowledge, across asymmetrical power structures and creating possibilities from the impossible (McFarlane 2011a). How Cities Learn builds from this scholarship by outlining a conceptual and practical analysis of policy mobilities that attends to the plethora of ordinary practices – be it through engagements with fellow practitioners, with their toolbox of material solutions, or after a particular moment of discovery – that form the assemblages of learning.
It is along this line of inquiry that How Cities Learn builds upon and extends the thinking of urban scholars, first by bringing concerns of power into question, and second by problematizing notions of governance at-a-distance. Certainly policy mobilities arguments have provided evidence that power is now disseminated across a host of diverse agents and agencies. In this book, I ground policy mobilities within the adopting locality so as to suggest that power is always exercised in situ, although in the case of policy mobilities it often seems as if power is furthered by external authorities. Indeed, policy mobilities is a practice of both embracing extra-territorial thinking, but equally so a means through which local actors exploit international advocates and their policy models to justify preordained decisions, which might otherwise be resisted by local politics. Thus policy mobilities, though global in nature, is an inherently local process, one that is best exposed by scrutinizing the actors and their actions within the adopting locality, and then tracing back through their rationale for implementing a policy, product or practice also found elsewhere.
Accordingly, I employ the process of “tracing” to better understand policy mobilities (Wood 2020). This approach draws on Robinson’s three genetic and generative approaches to comparative urbanism: “composing” – that is examining the specific similarities and dissimilarities within a range of instances; “launching” – that is starting from anywhere and then putting the analysis to work anywhere; and “tracing”
