Megaregions: Globalization's New Urban Form? Edited by John Harrison and Michael Hoyler, xi and 270 pp.; diagrs.; tables; index. Cheltenham, Glos., U.K.: Edward Elgar, 2015. $130, (cloth), ISBN 9781782547891.
Positioning Megaregions - Foundations
From the multiplicity of terminologies used to describe the emerging functional scales and composition of t he world's twenty first century urban landscapes, John Harrison and Michael Hoyler have taken a prominent United States (US) term as the title for their edited volume of essays - Megaregions . This decision goes a long way in explaining their mission: to de-bunk “megaregions” “can-do”, “hype” and “hysteria”, recently popularised by American cult urban writers.
Yet, as the book's contributing authors frequently point out, the “imaginary” linked to the contemporary megaregion has in reality been in emergence for decades, dating back to the early twentieth century ideas of Patrick Geddes and their later US re-working by Lewis Mumford, Jean Gottman, etc. Representations of urbanisation processes even back then, highlighted the growth of the world's major cities as not simply a question of increasing size but of global constitution (Pain 2017). However Harrison and Hoyler stress at the outset that the reader should heed August Hecksher's warning of fifty years ago that an awe-inspiring spatial concept can allow dangerous “misconceptions” to take root (1).They re-apply Hecksher's prophetic anxiety about the dramatic power of Gottman's mid-twentieth century ‘megalopolis' (heralded as a new stage in human civilization) to the ‘megaregion' (4).
In line with Gottman's prediction that the interwoven urban formation of 25 million population on the US North Eastern seaboard was the beginning of a new American urban demographic, a rash of twenty first century megaregions expected to represent more than 70 per cent of the nation's population growth by 2050, has now been identified by independent research and planning organisation, the US Regional Plan Association (2006a, 4). According to Harrison and Hoyler, all the excitement whipped up by the populist narrative of new millennium ‘regional globalization' has led this iconic US-style megaregion to become regarded as the globally competitive urban form of the future (for example, Ohmae 1999; Scott 2001; Porter 2001; Florida, Gulden and Mellander 2008; Short 2010).
The starting premise for the book then is that the power of the megaregion as the symbol of economic competitiveness has triggered an international epidemic of megaregion imaginings, reflecting a naïve assumption that this new phenomenon can be easily delineated and so used to territorial advantage. Its editors are well equipped to provide an innovative addition to the literature on this subject, combining Harrison's theoretical fluency in debate on the meaning and existence of the region and Hoyler's hands-on experience of European urban and regional empirical analysis. Critical insights into territorial rescaling introduced to geo-political discourse by Neil Brenner are drawn on to inform a distinctive mission for the volume: to shed light on the construction of the megaregion, academically and politically (see for example Brenner 1998a, b, 1999; Brenner 2004, 2009). Organised in ten chapters, a central purpose then is to dig deep in unearthing and exposing the megaregion as a fuzzy and generally too simplistically defined and researched concept invoked as a competitive device in the US and beyond.
Frailties - The Volume
The bold assertion for critical analysis in the volume is that the megaregion constitutes “globalization's new urban form”. We are told: “What marks megaregions out from other spatial concepts presently is that for the first time in history the megaregion has become a truly global concept” (14). But, unravelling the significance of the megaregion as a spatial imaginary beyond its US academic and geo-political framing is, not surprisingly, not straightforward.
In the introductory chapter to the volume Harrison and Hoyler present a useful typology of common concepts and analytical approaches (seen as megaregion “variants” 8–10) followed by brief discussion of some basic distinctions, commonalities and deficiencies. Setting analytical parameters was understood to be important “because it ensures that as researchers we begin with the same objects under our consideration” (237). Contributing authors were expected to consider, first, how robust are the foundations of megaregion conceptual construction; second, the methodological challenges of researching megaregions; and, third, whether megaregions really are globalization's new urban form and, if not, whether there are “more suitable” spatial frameworks (22). The intention is to advance critical analysis beyond consideration of “the what and where”, to “the who , the how and the why” of megaregions (22-23). Nonetheless, the difficulty of providing a comparative dimension to analysis beyond the introduction in an edited volume is plainly evident.
Harrison and Hoyler draw out some key threads emerging from the collection in their conclusion however the detail of divergences between what seem, superficially, to be similar extant urban processes and territorial constructions presenting in different situations, is not covered systematically across the essays. An intellectual challenge for the reader then is to establish the significance, or not, of potential theoretical and empirical specificities and nuances, important in rigorous analysis of a “chaotic concept” (4).
An obvious editorial challenge has clearly been posed by the decision to make just one spatial concept (mainly associated with one country) the focus of attention. As Harrison and Hoyler discuss in conclusion, “privileging megaregions over other spatial imaginaries … presents a compelling narrative that only tells part of the story” (237) and this is especially problematic given the insistent editorial focus on “more critical analyses of megaregions, megaregionality and the megaregion concept” (22). Although the problem is dealt with to an extent by reference to megaregionalism as a political strategy (which potentially has far-reaching significance), the question to what extent alternative concepts and constructs are simply ‘megaregion variants', and to what extent they represent distinctive development and/or geo-political processes ultimately proves hard to establish. Furthermore the megaregion is not simply a home-grown US imaginary, so determining its real symbolic influence beyond the US is self-evidently challenging.
Gottman's megalopolis introduced to the US an interpretation of mega-urbanisation as part of the solution to its social and economic problems, breaking away from antecedents that had highlighted it as a threat to civilisation. But, as Harrison and Hoyler point out, the modern US megaregion has also borrowed ideas from recent European spatial planning thinking (Mehlbye 2000; Faludi 2002). And the travel of ideas, and their direction over time, between actors and places, is fundamentally important to understanding the positioning of spatial concepts and their academic and policy invocations - in other words, the who , the how and the why of megaregions - as will be illustrated later in looking back across the volume. In consequence, unravelling the power of the megaregion as a globalization reality and/or narrative is essentially problematic.
Megaregions presents an excellent collection of spatial imaginary cameos drawn from the US and beyond, together with theoretically searching and provocative commentary from its editors. However the reader new to this field of regional analysis and discourse especially, must therefore be critically alert methodologically and dialectically in traversing its varied attempts to pin down “the foundations, frailties and futures of megaregional research” (4).
The Megaregions Essays
Markus Hesse (Chapter 2) opens up the conversation about ‘mega-' region conceptualisation at a theoretically high-level by exploring its linked metaphorical and representational epistemologies. His fluent analysis draws attention to the significance of mega-narratives, including the “globalization rationale” (43), in the (unhelpful) construction of essentialist representations of space. This essay therefore usefully positions the megaregion in the longstanding spatial narrative that aligns competitiveness with size. Hesse's constructivist thinking provides a discursive theoretical context for the contributions that follow. The importance of “language, communication and discursive interaction” is highlighted (39) but so too is the need “to be concerned with the materiality of real-world problems” (43). Hesse's call for balanced attention to dialectical and material considerations is especially pertinent in light of the danger (later referred to in Chapter 9 by Billy Fleming) that critical analysis may demote the importance of taking seriously research into new spaces for urban analysis.
A line of thinking not pursued here however is the possibility that understanding evolving relationships between urban imaginaries, political projects, and material real-world problems, may actually be assisted by reference to a particular globalization rationale, the rationale of qualitative “socio-technological transition” (Pain and Van Hamme 2014, 5). After all, Mumford's (anti-mega) dystopic vision of the very large city (36) resonated with that of Ebenezer Howard, creator of the ‘Social' or ‘Garden City' multi-centre urban vision. Yet this multi-centre or ‘polycentric' imaginary was later to be used in economic boosterism strategies at diverse territorial scales. From the ‘Randstad' Netherlands project that began in 1958 (Lambregts 2006) to later Europe-wide promotion of the ‘polycentric urban region' (PUR) (Pain 2011a) and recent ‘cross-border' regional constellations (see also Chapter 7), the multi-centre imaginary has, on the one hand, been subject to political manipulation in territorial rescaling strategies and, on the other hand, it has proved a less sustainable model than Howard could ever have predicted prior to mass automobile ownership in a globalizing society (Cochrane and Pain 2000; Halbert, Pain and Thierstein 2006; Pain 2010, 2011a, 2016). Evolving urban processes, communicative structures and material realities, are interactive over time hence attention to the local-global construction of space matters.
Following Hesse's lead, both David Wachsmuth (Chapter 3) and Alex Schafran (Chapter 4) similarly take a purposeful historical approach to evaluation and critique of the megaregion as over-generalised conceptually.
Focusing on the US in Chapter 3, Wachsmuth engages critically with US policy discourse, highlighting megaregions as “strategic terrains in which a multitude of differently scaled competitiveness strategies are being enacted” (52). He helpfully provides a detailed and reflective analysis of urbanised spaces as both internally and externally connected, “simultaneously both city and urban network” (51-52), a line of thinking that could have valuably been developed in Harrison and Hoyler's concluding chapter (10). Importantly he also questions the prevalent notion that megaregions have agency as competitive global economic actors. On the contrary, even when megaregions are strongly promoted, they are typically politically fragmented, contested spaces, as Stephen M. Wheeler later highlights. Furthermore, Wachsmuth draws attention to the critical relevance of understanding distinctions between different sources of megaregion functional connectivity (important also for Xu Zhang, Chapter 8); for example, the connectivity generated primarily by manufacturing production and/or by advanced producer services. The essay has an important role in the book in attending to the megaregion as an imaginary that is simultaneously politically constructed and at the same time an outcome of active urban processes.
Schafran's essay (Chapter 4) presents a polemical view of (presumed by Schafran) under-historicized academic research that has fed the megaregion imaginary and it's (assumed by Schafran) variants (75). One example, the 2003-06 ‘ Polynet : Sustainable Management of European Polycentric Mega-City Regions' study (briefly introduced by Harrison and Hoyler, 16-17) is singled out for particular scrutiny (Hall and Pain 2006).
Led by the late Sir Peter Hall and Kathy Pain (this author) in the UK, this research investigated the aforementioned multi-centre PUR imaginary in North West Europe from a novel functional perspective which incorporated ‘Globalization and World Cities Network' (GaWC) ‘world city network analysis' pioneered by Peter Taylor (Taylor 2004; Pain and Hall 2008). By exploring, quantitatively and qualitatively, multi-scale business, informational and travel networks and flows that are interconnecting towns and cities physically and virtually in ‘mega-city region' spaces, Polynet shed light for the first time on the PUR as characterised by distinctive morphological and functional processes. But, regrettably, Schafran does not refer to the range of work reported on by the international research team, which includes important findings on PUR uneven geographies and differences, and their policy implications. He therefore expresses surprise to have discovered that “in one of the many ironies of megaregional research, it is from a generally ignored piece by two of global cities theory's greatest protagonists” (76), Taylor and Kathy Pain (this author), that an insightful process analysis of the Polynet results has emerged (Taylor and Pain 2007). Schafran seems to assume that the analysis appeared by magic from a “hail of numbers, rankings and schematic maps” that overshadows “what is happening on the ground” (78).
Nevertheless, three case studies are introduced to illustrate the piece's “practical use in advancing mega-regional research” (78). A number of Polynet insights re-emerge here, for example, megaregions “should be defined in part by the fact that their urban networks exceed any attempts to unify them politically and likely always will” (86) and as “a functional process inseparable from historicized urbanization” (90) - Schafran's assumption that Polynet was under-historicized is misplaced.
According to Schafran, Ludovic Halbert's Paris analysis for example, does not, but should, combine “political-historical and economic analysis” (81) . However this criticism seems unduly harsh given that Halbert explores political influences on the development of the Paris region since the publication of Jean-François Gravier's Paris et le desert français (1947, cited by Halbert 2006, 189) and also makes reference to work by Frederic Gilli (2006, 184) that is highly commended by Schafran (81). It can only be assumed that Schafran has not studied Halbert's research in detail, in particular his 2006 paper entitled “T he Polycentric City Region That Never Was” . It is not so surprising that they agree that Paris “is not truly polycentric and likely never will be” (83) since the process framework that Schafran employs in his ‘The Island of France' example was identified by the Polynet research, and Halbert's contribution to it. Taylor and Pain's, 2007, analysis did not appear by magic in the “wide-eyed hysteria” engendered by globalization that Schafran refers to (75) after all!
Wheeler's essay (Chapter 5) is an unexpected contribution to this book in that it looks back to the ‘deep green' environmentalist perspective of the nineteen seventies. Rare within this volume is positive reference to some big urban regions including London (99). On the other hand, the interrelationships between such agglomerations, the regional globalization process, and “local and sustainable communities” (97) required carefully considered fleshing out. For example, Wheeler proposes a need for “growth management” (99) for which ‘greenbelt' and reduced commuting strategies are prescribed (114). But, as the Polynet research revealed, urban containment policies for London and the Randstad, Netherlands, (both referred to by Wheeler as regional growth management successes) have proved unable to halt the emergence of functionally interconnected urbanised spaces extending far beyond their metropolitan boundaries with high dependency on environmentally unsustainable travel by car (Pain 2016). Vibrant “Jacobsian” urban growth processes can leap over urban green belts as they do Japanese mountains (Taylor and Pain 2007).
Unusually within this volume, the essay engages directly with real-world material and (fractured) planning and governance dilemmas (100 onwards) however there is a danger of over-simplifying urban processes by proposing un-contextualized policy prescriptions (see 114). ‘One size fits all' planning solutions imply the existence of a generalised regionalization process independent of local historical and geo-political contexts. Clearly, nuanced processes require nuanced responses.
The final four invited essays reflect their authors' experience of immersion in empirical regional analysis, adding an important research practice dimension to the collection. In Chapter 6, Michael R. Glass takes the focus on governance forward beyond Wheeler's emphasis on policy strategies. In contrast, he highlights that “there is no capacity to enact a new regional governance framework – at any scale – detached from the inherited and often overlapping political, social, and economic geographies of those spaces” (120). Geographic exigencies (changing geographic patterns and spatial dynamism) run alongside political exigencies (interregional competition and spatial rescaling). According to Glass, together, these exigencies preclude the development of the megaregion scale as a governable reality, as illustrated in his overview of regional government and governance in Western Pennsylvania and the Great Lakes area of the US.
The issue of scale is next approached in a European context by Lukas Smas and Peter Schmitt (Chapter 7) who present the case of the construction of ‘Norden', a specifically cross-border regional imaginary supported by European policy (158 - 159). An emergent Baltic Sea macro-region presents further exemplification of ways in which soft, networked, space is being ‘bordered' in line with national and European political agendas. This essay is particularly strongly empirically informed and, at the same time, it engages with theoretically important questions first raised by Brenner about the role of policy framing in the invention of re-scaled megaregion spaces intended to enhance Europe's global competitiveness (Brenner 1999; Brenner and Theodore 2002).
Zhang's China example (Chapter 8) is a similarly unpretentious account of the state of research knowledge in the case of the Pearl River Delta. The essay provides a useful contrast to the US and European contexts, illustrating the importance of research in uncovering nuanced megaregion processes and dynamics. It both depicts Chinese urban regionalisation as a historically and politically shaped process and urges that distinctions between specific situations be subject to rigorous empirical investigation to inform responses to real development challenges in rapidly urbanising countries like China.
Finally, back to the US context, Fleming's essay in Chapter 9 also stands out as empirically well-informed. Importantly this essay enriches a space for contemplation that is under-attended to elsewhere in the book by reflecting on interviews with real-world megaregion actors, as opposed to simply assuming their motivations for engagement with this inter-urban functional scale. Fleming calls for research, rather than just critical commentary, to inform urban process understanding, thus delivering an important message to take from the book.
Spatial Imaginaries Reconsidered
Harrison and Hoyler's concluding chapter (10) endeavours to draw together thinking from across the volume. The reader is reminded of the book's intended focus on the who , how and why of megaregions, in short, on questions of “agency”, “process” and “specific interests” (230). However the bold editorial decision to single out one spatial concept for attention and critique, the megaregion, inevitably conditions the lines of discussion here: this “compelling narrative … only tells part of the story” (237).
US ‘Cali Baja', ‘Hampton Roads-Richmond' (231 - 234), and European ‘PAR-LON' (234 - 236) cases are introduced as examples of recent political projects invoking new megaregional frames for territorial rescaling. But the Paris-London, PAR-LON, imaginary, speculated here to be a new political “space of engagement”, serves to illustrate the importance of Harrison and Hoyler's final reminder at the close of the book that a powerful imaginary must be treated carefully (251). PAR-LON is not so new and is not such an empty French territorial political fabrication as is suggested (235). The ‘megaregions-critique' lens employed here only tells part of the story.
Citing an open letter in 2014 from Paris Deputy Mayor, Anne Hidalgo, to Boris Johnson, London Mayor, PAR-LON is proposed by Harrison and Hoyler as an imaginary that is representative of Paris “reaching out to London, much like Cali Baja is reaching out to San Diego and Los Angeles.” (235). But the PAR-LON concept was originally introduced in a GaWC research paper (not cited by Harrison and Hoyler) written five years before the date of Hidalgo's letter (Halbert and Pain 2009).
PAR-LON is represented a s a “further example of endeavours to politically construct a megaregional space of engagement in order to secure certain economic interests from external threats which seek to undermine or dissolve them” (235). However, Halbert and Pain's conceptualisation, which drew on Polynet analysis, on the contrary, reflected a de-territorialised understanding of Paris-London relations as real and actual functionally networked “flow-places”, or “an operational implementation of Castells ‘spaces of flows'" at the “intra-metropolitan level” (Castells 1996):
Halbert and Pain's PAR-LON is indicative of actual Paris-London relations that lend credence to Hidalgo's claim, demonstrating how susceptible a concept is to uncertain meanings, intentions and interpretations. This leads to three important analytical observations.
First, as Harrison and Hoyler observe in reflecting back on the volume, “Megaregions always need to be considered within the broader contours of global urban studies” (238). They admit that:
As noted by Wachsmuth in Chapter 3, megaregion analysis needs to include complex inter-scale urban and social network relations under revision and reconstruction. Awareness of connectivities beyond “static attributes, such as the location of activities” in Polynet , is critically important in understanding the stretching of contemporary urban relations in softening, networked spaces, including the process of regional globalization (Halbert and Pain 2009, 15; Pain 2011a, b).
Second, PAR-LON illustrates the importance of Harrison and Hoyler's focus in the book on the who , the how and the why, of the megaregion. Appropriate searching questions are raised in relation to PAR-LON, for example, “why London”, “why now?” (236). But establishing meaningful answers to such questions requires a semiotic approach to analysis that takes into account evolving communicative contexts: “megaregions mean different things, to different people, in different contexts” (237).
Finally, it is not known whether Hidalgo was personally aware of and influenced by Polynet findings on Paris-London relations when she wrote her letter to Johnson. However this is very possible given the number of research publications and presentations to French academic, policy and practitioner audiences on this subject (for example, Halbert, Pain and Taylor 2007; Pain 2009; Halbert and Pain 2010; Pain 2011b). So Hidalgo's Paris-London imaginary may not just “be the vehicle for communicating a particular story to its chosen audience” as inferred by Harrison and Hoyler (235-236), instead it may really be part of the story. Was Hidalgo's “courting of Johnson and London” a genuine attempt to plan and govern in a manner that reflects PAR-LON functional relations? The point is that we cannot say. Questions about “agency”, “process” and “specific interests” (230) in spatial imaginary construction are context dependent and so call for a semiotic approach in analysis. Focusing on the exemplification of megaregions geopolitical semantics in critical analysis tells a partial story… These same analytical observations are further emphasised in a US context.
Megaregion Excursions in Retrospect
In Chapter 1, the US megaregion is introduced by Harrison and Hoyler as emanating from a form-focused analytical approach that has an “unwitting tendency … to infer and/or assume the functional coherence of the megaregional spaces they identify” (15) . Further, US Department of Transportation (DoT) funding to megaregions research is discussed as having encouraged a focus that is “almost exclusively on issues of transportation” (20; footnote 8, 23):
Drawing on the personal experience of this author of interactions with the America 2050 process since 2004 as co-director of the Polynet study, introduces other potential dimensions to Harrison and Hoyler's megaregions construction story. As Fleming illustrates in Chapter 9, megaregional planning research and pedagogy are complex.
For instance, research conducted by RPA ‘National Committee for America 2050' member, Robert E. Lang, ‘From Megalopolis to Megapolitan: Framework for Planning Transmetropolitan Development in the US', incorporated GaWC world city network analysis also used in Polynet, which was by then underway (Taylor 2004; Taylor and Lang 2004; Taylor, Evans and Pain 2006). Supported by US Lincoln Foundation funding, Lang's 2004 project introduced a new lens to academic debate on US metropolitan regionalism. Transmetropolitan clusters were studied as functionally and spatially connected ‘ Megapolitan' spaces defined by inter-city ‘place-flow' relations as opposed to form-focused morphological relations (Lang and Taylor 2005). And this functional ‘megaregions variant' was undoubtedly influential in RPA thinking (Todorovich 2007a, b; Regional Plan Association 2008). After all, t he research results were to be shared with RPA research partners at the University of Pennsylvania ‘Super City' researchers and the Lincoln Institute of Land Policy. “Functional coherence of the megaregional spaces” should t herefore not be represented simply as inferred and/or assumed by the “‘North American' school of megaregionalists” (15) . The “'European School' of megaregionalists”, “function-dominated approach” has undoubtedly had a presence in US megaregions debate. This author was certainly active in communicating Polynet methods and results, and their implications for the US, at intensive RPA and Lincoln Institute organised research events in Vienna, Austria, and Healdsburg, California, where the Taylor and Pain, 2007, paper was presented.
The findings from both Polynet and Lang's research emphasized the problem of environmentally unsustainable commuting by automobile posed by the trans-metropolitan growth process, and therefore the need for strategic planning (for example, Lang and Dhavale, 2005a, b). Lang proposed that federal aid in areas such as transportation could be tied to functional mega politan, instead of metro politan, planning. His ambitious ultimate goal was
It could be speculated then, first, that contrary to Harrison and Hoyler's conjecture that US DoT research funding played a major part in shaping the America 2050 agenda, the focus on transportation issues was sharpened by the megapolitans and Polynet functional research findings (Carbonell and Yaro 2005). Second, it could be speculated also that the megapolitans and Polynet emphasis on the need for mega-planning contributed to a megaregions focus on issues of form and size.
As Harrison and Hoyler (21) and Fleming (212) note, Lang had referred to the US Census Bureau's Combined Statistical Areas (CSAs) and population data to inform the megapolitans' ‘place' component. Daily commuting data were used to illustrate the physical extent of European mega-city region formations in Polynet . Or, on the other hand, there may have simply been a failure to appreciate the relevance of complex inter-scale city network relations under revision and reconstruction for the US situation. A 2009 review of the megaregions methodology by RPA staff member, Yoav Hagler, suggests that this too could be part of the megaregions construction story (Hagler 2009).
In his review, Hagler proposed that adding to existing population and employment analyses already used by researchers in defining megaregions, data on intercity passenger travel and freight movement, would “move toward answering many of the unanswered questions on connectivity that were not answered in the RPA process” (2009, 6, 8). However he claimed city network relations to be unrepresentative of local physical US realities, thereby (arguably) diverting attention away from the US megaregion as a globally networked functional reality:
How significant was Hagler's report in influencing subsequent mega-regions methodological decision-making? As in the case of influences and motivations in the PAR-LON example, we cannot say. What this brief reflection on the evolution of megaregions construction does illustrate however is just how fuzzy and messy the story can be. In consequence, an analytical focus on geopolitical semantics can all too easily skip over aspects of the story that are highly pertinent to questions of agency, process and specific interests . Qualitative research by Fleming (also undertaken with business, policy and practitioner actors in the Polynet study) demonstrates the value of including megaregional actors in the conversation about these questions.
This author's interaction with the US megaregions project since 2004 endorses Fleming's findings on the evolutionary and multi-faceted nature of US megaregional research and planning construction (201). It has also suggested that the RPA mission has been founded on real concern for the promotion of a more sustainable US urban development pattern (see also Pushkarev 1969, cited by Todorovich 2007b, 10; Lincoln Institute of Land Policy, Regional Plan Association and University of Pennsylvania School of Design 2004). Issues that were the focus of attention in 2004 were US population growth, social and economic disparities within and between American regions, overcrowded and deteriorating infrastructures, and climate change mitigation (RPA 2006a; Todorovich 2011, 263). Past research by Lang has equally been concerned with issues of equity, including affordable housing and gated communities. In other words, megaregional research interests in the US (and in Europe) do go beyond a focus on “the wealthy, the powerful, or the creative” functional networks, a “narrow geo-economic logic” and the “partial explanation of the phenomena of megaregionality” discussed by Schafran (78). Fleming notes the diverse thematic areas that US megaregional actors are now engaging with (214), including a deeper ecological perspective (223).
That is not to say that economic growth, and US global competitiveness, has not been prioritised alongside sustainable transportation and planning however (Sassen 2007; Lang and Nelson 2007, 2009). Under the influence of inputs from European spatial planners espousing the merits of the polycentric urban form, there has been an assumption that, with judicious European-style planning, economic growth, social cohesion and environmentally sustainable development can go hand-in-hand with metropolitan regionalisation (Regional Plan Association 2006a, 14, 2006b; Todorovich 2007b; Montgomery 2011; Pain 2011a). In 2005, former RPA President Robert Yaro and Armando Carbonell (Lincoln Institute of Land Policy) went so far as to speak of an “American Spatial Development Perspective” emulating that in Europe which, according to Andreas Faludi, “turned into” the America 2050 exercise (Armando and Yaro 2005; Faludi 2010, xii).
But the Polynet research introduced to policy debate in Europe and the US (especially at RPA/Lincoln Institute meetings in Vienna and Healdsburg) evidence demonstrating that this is by no means a given (Halbert, Pain and Thierstein 2006; Pain 2011a; Pain and Van Hamme 2014). This is overlooked by Harrison and Hoyler's claim that “there has been little or no debate asking if megaregions are internally coherent spaces”, Schafran being “one notable exception” (10). Combining virtual and physical (commuting and business) flow with business network and institutional and policy analyses in the Polynet research produced a deeper understanding of regional globalisation as functionally differentiated and geographically uneven in all North West European PUR cases studied. But this only serves to endorse the “compelling” megaregions case for coordination and infrastructure development investments that seems to be questioned by Harrison and Hoyler at the start of the book (14–15).
Coda - New Spaces for Research
Undoubtedly, the distinctive contribution of the Megaregions volume is the light that it sheds on the dual construction of the megaregion, academically and politically. This is further exemplified by the PAR-LON and US megaregional construction processes discussed in this article. Despite the best intentions of leading megaregional actors, experience suggests that communicative meanings, intentions and interpretations can get dangerously mixed and confused in the megaregions construction maze.
US research following in the wake of Ross (2009) for example, continues to seek to demonstrate how megaregion geography can aid business synergies , as in the case of e-retail developments, freight distribution and routing cost-efficiencies, etc. Implicit in this agenda is the notion that business and commercial decision-making should respond to new geographical realities whereas a city networks approach to analysis demonstrates that business and commercial decisions, in practice, play a critical part in the generation of spatial realities . Clearly, the theoretical framing of urban processes and of their research has profound political significance as Harrison and Hoyler are anxious to demonstrate.
In concluding the volume, Harrison and Hoyler develop this point further in an attempt to answer the question whether the megaregion really is globalization's new urban form. They see the megaregions orthodoxy as principally opposed by analysis that prioritizes localized ‘spaces of the megaregion' (245). But a city-networks research approach shows that social, economic and material realities that are functionally interconnecting spaces at diverse scales are both locally and globally constructed and felt (Cochrane and Pain 2000). T he process of “ the extension and intensification of global city functional relations … beyond metropolitan boundaries” (inter-scale ‘megaregional spaces') must therefore remain a critical area for in-depth investigation, as must the issue of what are “appropriate forms of institutional structure, planning and governance arrangements and democratic engagement” (Harrison and Pain 2012, 1). Ultimately, Harrison and Hoyler strongly advocate combining “macro-“ and “micro-level” analysis (245). This means that to megaregions ‘can't-do' voices that need to be heard, the (generally under-attended to) voices of policy and practitioner actors, genuinely perplexed by the challenges that networked urbanisation and geographic exigencies present, must be added .
Fleming's call for more research, as opposed to just critical commentary, is apposite. Me garegions, provides a series of thought-provoking and question-prompting interjections to inspire and prompt new research agendas exploring these evolving inter-scale urban spaces and their complex communicative contexts .
