About the Book

Cities in the 21 Century provides an overview of contemporary urban development.Written by more than thirty major academic specialists from different countries, itprovides information on and analysis of the global network of cities, changes inurban form, environmental problems, the role of technologies and knowledge,socioeconomic developments and finally the challenge of urban governance.

In the mid-20th century, architect and planner Josep Lluís Sert wondered if cities could survive; in theearly 21st century we see that cities have not only survived but have grown as never before. Citiestoday are engines of production and trade, forges of scientific and technological innovation andcrucibles of social change. Urbanisation is a major driver of change in contemporary societies; it is aprocess that involves acute social inequalities and serious environmental problems, but also offersopportunities to move towards a future of greater prosperity, environmental sustainability and socialjustice.

With case studies on 30 cities in five continents and a selection of infographics illustrating thesedynamic cities, this edited volume is an essential resource for planners and students of urbanisationand urban change.

Dimensions of the Future City Matthew Claudel and Carlo Ratti

1. Introduction: the “death of cities” mirage

At the dawn of the digital revolution it was widely believed that the Internet – and the instant, ubiquitous connectivity that it entailed – would dramatically reduce the importance of physical space, to the point that scholars predicted a “death of cities.”1 Yet history has proven the opposite. The world is urbanizing at an unprecedented rate, and rapidly compounding advances in technology have sparked a redefinition of urban space at the convergence of bits and atoms. With high-resolution pervasive sensing, sophisticated analysis, and fine-grained actuation in physical space, cities have become digitally-integrated systems. In light of this metropolitan transformation, ‘smart cities’ have emerged as a new field hybridizing computing and urbanism. This chapter reviews current research in the field and suggests possible lines of investigation through categorical dimensions of urban space that could direct smart city development in the future.

During the 1990s, with the rapid introduction of the Internet and its exponential adoption rate, there was a common belief that physical space would be stripped of its significance by a ubiquitous, networked ‘information space.’ The Internet represented an instantaneous and spatially-indiscriminate connective tissue, and in its shadow, a chorus of voices predicted a future when “distance is irrelevant”2 as people would be “cut loose from fixed locations”, 3 by a global “infobahn” 4 bringing with it a “Global Village” 5 condition. In her book The Death of Distance, Cairncross elaborated an economic, social, and civic argument in the wake of the telecommunication revolution, characterizing the internet as “a peek at the communications future: a world in which transmitting information costs almost nothing, in which distance is irrelevant, and in which any amount of content is instantly accessible.”6 Gilder extended the idea and magnified a prevailing view of the impending urban dissolution with his statement that “cities are leftover baggage from the industrial era… we are heading for the death of cities.”7 Dense urban space – formerly the enabler of human action and inter-action – would be useless in the wake of the global network, as information could be sent and received ubiquitously and instantaneously.

Habitation, leisure and production would be unmoored as activity shed its spatial scripting. “The post-information age will remove the limitations of geography,” predicted Negroponte in his 1995 Being Digital, “Digital living will include less and less dependence upon being in a specific place at a specific time, and the transmission of place itself will start to become possible.”8 And the first physical space to be dissolved and transmitted would be the workplace – it was thought that a new generation of white-collar intelligentsia would trade cubicles for home offices, and bitrates would replace commute times. Why go to work when work could come to you? employees would ask, and even more importantly, What is the use of cities?

The end of the millennium answered these questions and confirmed broader predictions of a profound reconfiguring of spatio-temporal relationships… but not the death of cities. Yes, employees were liberated to work from a home office, for example, but would they choose to? The answer, proven by millions of workers, is no. A recent study by the Telework Research Network, found that only 2.5% the workforce (excluding self employed or volunteer workers) consider home their primary workplace. 9 This year Yahoo instituted a policy prohibiting employees from telecommuting, with a memo stating: “some of the best decisions and insights come from hallway and cafeteria discussions, meeting new people, and impromptu team meetings.” 10 Beyond the workplace, humans crave spatially-dependent stimulus, whether natural beauty or magnificent architecture, human connectivity or the chaotic serendipity of communal space. “If you can locate anywhere, you will go where it’s nice, or where it is culturally stimulating… Cities and towns with unique architectural environments and cultural traditions stand to benefit from the new locational freedom in a similar fashion,”11 noted Mitchell.

The Internet did not kill cities, but neither did it leave them unaffected. Far from the predicted corrosive effect of networks, the dynamic virtual overlay is augmenting and redefining physical space today. Cities have not withered, but in fact emerged as a vital complement to virtual activity – perhaps more important than ever before. As its digital and material dimensions continue to merge and blur, urban space becomes the crucible for actions and re-actions between bits and atoms, all to the benefit of human experience. This is the genesis of the smart city: urban space reinforced, reinvented and reinvigorated by a virtual dimension.

This hybrid networked space will be reinforced by the rapid shrinking and dissipation of technology. Just as personal computing evolved from building-scale mainframes to desktops to laptops to pocketable smartphones – and correspondingly infiltrated every dimension of daily life – so too will the devices that enable fine-grained sensing and actuation in physical space suffuse our cities. “Ubiquitous computing,” 12 (or more playfully “smart dust”13) constitutes an invisible networked fabric with repercussions in the material dimension. The micro and the macro are engaged in an accelerating symbiosis – technology is atomized to the nano-scale while networks grow and connect

to encompass every dimension of habitation – and at the centre is the field of smart cities.

2. The future city: network mediated through place

The engineer’s response is to implement sensing and actuating tools to optimize the system – treating cities as ‘computers in open air’ and labeling them ‘smart’. Urban overhaul is a common mentality today, and the possibility of engineered urban space has piqued the interest of Information Technology companies worldwide – is this uncharted (and highly lucrative) territory? With this guiding question, the domain of smart cities has been eagerly pioneered by large corporations such as IBM and Microsoft, becoming the subject of top-down, cohesive planning initiatives like Masdar (Siemens) and Songdo (Cisco). Information Technology companies are partnering with traditional architects and politicians to mint smart cities around the globe, in a race for efficiency and sustainability. A 2013 peer-reviewed article on “Bootstrapping Smart Cities” posits a framework for the effective implementation of smart cities, based on the emergence of heterogeneous “independent smart city departments (or the equivalent)... much like today's well accepted IT departments,”14 operating at the intersection of political and technological players. Such systems would instantiate places where the “urban environment function[s] as an information centre. Being in a city becomes synonymous with being in an extremely intense and dense information loop.”15 These integrated smart cities perform with unparalleled efficiency (whether resources, transportation, or infrastructure), enabled by digitally-controlled circuitry and virtual operating systems, ultimately transforming urban space into a living lab.

But beyond the efficient cohabitation that top-down urban computing systems imply, cities are a place for community. Their non-quantifiable dimensions are more likely to emerge from a combination of bottom-up and top-down. The third and final phase of the smart city system proposed by Vilajosana et al. is a “fun/leisure dimension”16 that can only be enacted by inhabitants themselves. This citizen-centric element of smart cities has increasingly focused the attention of scholars, yielding rigorous analysis and case studies. A 2013 article titled “Fostering participation in smart cities” explores urban crowdsensing and the possibilities of “automat[ing] the organization of spontaneous and impromptu collaborations of large groups of people participating in collective actions,”17 at its core, this would be a coherent system that instrumentalizes the potential of an engaged public-at-large. A nuanced and multidimensional understanding of smart cities – one that encompasses bottom-up and top-down – reveals their position as the chaotic common ground for interrelated and co-dependent stakeholders. In his comprehensive overview of smart city evolution, Anthony Townsend scrutinizes the balance of a “new generation of technology barons, entrepreneurs, mayors, and civic coders,” in the context of contemporary and future urban space, ultimately “offering a new civics for building communities: together, one click at a time.”18 14 Vilajosana, Ignasi. Jordi Llosa, Borja Martinez, Marc Domingo-Prieto, Albert Angles and Xavier Vilajosana, “Bootstrapping smart cities through a self-sustainable model based on big data flows,” IEEE Communications Magazine, vol. 51, no. 6, June 2013. 15 Sassen, Saskia. “Cities today: a new frontier for major developments.” 2009. 16 Vilajosana, Ignasi. 2013. 17 Giuseppe Cardone, Luca Foschini, Paolo Bellavista, Antonio Corradi, Cristian Borcea, Manoop Talasila and Reza Curtmola, “Fostering ParticipAction in smart cities: a geo-social crowdsensing platform,” IEEE Communications Magazine, vol. 51, no. 6, June 2013. 18 Townsend, Anthony. Smart cities: big data, civic hackers, and the quest for a new utopia. WW Norton & Co, 2013.

At the cusp of a new era in the history of cities – the collision of bits and atoms and the spatialization of the Information Age – this chapter outlines current trends that have the power to inform urban development over the years to come. Based on an assay of present scholarship and action relating to cities, these dimensions point toward an urban future generated from both the top down and the bottom up; future in which the network is mediated through place, becoming fine-grained, local, and individual; in which technology goes beyond descriptive and operational to integrate culture; in which citizens have an active stake in their habitation ecosystem and are empowered to ‘hack’ the urban source code surrounding them; in which new economies coalesce, based not on monetary transaction but on social value or environmental impact – backed by a ‘gold standard’ of social networks; in a process of reverse-engineering the future, this urban space will be instantiated through the following integral dimensions.

3. Changing trends for the urban future

Participation 2.0

Images of digitally-enabled socio-political uprisings captured the world’s collective attention in recent years. These were instances of excessive friction generated within virtual social networks, ultimately discharging as violent civic action in physical space. The net result is a proof that in the context of political engagement, a tangible public sphere is the catalyst for group dynamics sewn by digital connectivity. But the same energy that rent public spaces can be tapped to work constructively in the same dimension, shifting focus from Civic Protest 2.0 and onto Civic Participation 2.0 – an idea that was elaborated in Scientific American’s August 2011 special issue titled Better Greener Smarter Cities. A multitude of 311-style apps allow inhabitants of a city to report the easily-resolved problems they come across in daily life – from potholes to cars rolling through bike lanes. These citizen-watchdog systems give urban space a new pair of reflexive eyes and bring citizens together to fix their own neighborhoods. The order of involvement is directly one to one: citizens will point out problems and opportunities and jointly contribute to solving them. Anyone can become what Boston’s former Mayor Menino termed “New Urban Mechanics.”

Smartphone/Smartcity (or, The City in Your Pocket) Smartphones are the active components of spatialized networks, serving to sense and gather, to connect and to distribute information. As a result, they are increasingly enmeshed in the urban tissue: mediating space and communities through a smartphone will soon be as integral to urban experience as asphalt or streetlights. Smartphones will not replace built space (they cannot not provide shelter) but they will augment it (connecting travelers and hosts or booking a last minute hotel room). The miniaturized computer becomes an extension of corporeal occupation of space. But as Hayles notes, the human-as-cyborg metaphor that Donna Haraway introduced in 1991 is too singular, “quite simply, it is not networked enough.”19 The idea that the human body would be augmented with technology is no longer revolutionary – what smartphones show is that

19 Hayles, N. Katherine. Unfinished Work: From Cyborg to Cognisphere. 2006. Published in: Architectural Theories of the Environment: Posthuman Territory. Routledge, 2012

we are not only digitally assimilated, but digitally connected. Smartphones are a tool that generates and relies on crowd-sourced big data, providing an interface for users to simultaneously digest information and apply it constructively in daily life. Mobile phones serve as a lens into and out of the digital dimension, through which mass quantities of data – including messages, photos, preferences, habits, encounters, location and more – are streamed in real time. Not only will smartphones unlock new means of efficiency, they will enable an unprecedented breadth and quality of human interaction. Social networks are spatialized through the personal digital interface.

[INSERT FIGURE 2 HERE]

The City That Speaks Unlocking access to all databases in real time – from transport to groceries to retail to library books – the digital blanket over physical space becomes more and more fine-grained, ultimately a pervasive “Internet of Things”.20 Responsive objects will be realized through the suffusion of ubiquitous computing into formerly mute materials. Every object in and of cities will tell a story. Furthermore, digitally-augmented physical materials will allow information transmission processes to be folded into the constituent fabric of architecture and objects themselves, serving as a bidirectional communication interface. Information was formerly displayed unidirectionally on screens, but in the future, spaces and objects might have the capacity to learn from human beings through interaction. Not only will objects communicate with people, they will increasingly interact with one another – for example, a car turning on the home heater five minutes before it pulls into the garage. Habitation space comes alive with a sentient and responsive dimension as every thing communicates across the network.

[INSERT FIGURE 3 HERE]

The Passenger City

Individual objects are learning from humans, learning from each other, and speaking in their own languages – forming a growing and increasingly independent ecosystem. As the same intelligence is embedded into cars, they approach an event horizon of automotive automation. When a car knows the location and destination of every other car on the road – as well as the character of the road itself – it can drive on its own, safely and efficiently. In an autonomous vehicle network, cars can determine their paths to optimize traffic flow on the systems level. Traffic lights become irrelevant, accidents obsolete, and excuses for tardiness suspicious. But most importantly, self-driving vehicles stand to dramatically blur the distinction between public and private transit. A single car can run dozens of trajectories throughout the day as it is shared between members of a family, friends in a social network, or the community at large. Rather than simply driving to and from the office and idling, unused, in a parking garage for the remaining twenty three hours of the day, each car will be constantly active and efficiently employed – yet with as much privacy, comfort and convenient routing as private vehicles have traditionally offered. At the tipping point of automation, the same number of people can arrive at the 20 Ashton, Kevin. "That 'Internet of Things' Thing, in the real world things matter more than ideas." RFID Journal. 22 June 2009.

same number of destinations in the same span of time, but using a fraction of the vehicles.21

Directed Energies The systematic improvements ushered in by intelligent technologies will transform climate control systems of the future. Just as powerful networks can optimize traffic flows, they can orchestrate energy distribution in cities – from smart grids to heating and cooling at the building scale – and dramatically reduce energy loads. Climate control is a clear example: the earliest form of habitation technology was the primordial grotto, and over the course of human history the evolution of temperature systems has been a trend toward decentralization. From the cave to the fire pit to Victorian pipes to central heating and suburban thermostats, man exerts more and more command of his climate. Yet today’s combination of central heating and itinerant lifestyles has exacerbated a dramatic asymmetry between human occupancy and energy use. Entire homes are heated during the day when residents are at work or school, and when they are home, empty areas of the house are indiscriminately kept as warm as those in active use. To ensure constant comfort, man heats every space he might possibly inhabit. Intelligent thermostats like The Nest learn from residents and optimize temperature patterns over time, but the next leap will be to exercise the same degree of control over space – synchronizing heat with where people are. In the future, an individual ‘thermal cloud’ could follow each human throughout a building, ensuring ubiquitous personal comfort while minimizing overall heat requirements.

[INSERT FIGURE 5 HERE]

Disciplines Beyond Silos The same spatial liberation that has unmoored personal atmospheres and productive work environments might correspondingly emancipate intellectual disciplines. Not only where we are but what we do can be rendered flexible and recombinable. Materials, specialties, or domains are less defined with the progressive augmentation of interfaces between them: connective tools, common languages and interwoven compatible systems. Fed by increased access to knowledge and communication, a growing class of “professional amateurs”22 might one day drive the work force. Yet far from rendering expertise obsolete, this is a phenomenon that expands the purview of any given specialty beyond its traditional demarcations, allowing for superpositions and hybridizations, both intellectually and professionally. In fact, the field of scientific publication has already felt the impact of this disciplinary cross-pollination over the past century. In an analysis of over 2 million patents and 20 million papers published since 1955, researchers at Northwestern University found that “in the early 1950s, the most cited paper in any year was more likely to have been written by a single author than a team, but this pattern

reversed decades ago. And the citation gap continues to widen.”23 The lone genius has been replaced by heterogeneous groups that amalgamate skills and capacities, ultimately bolstered by intellectual diversity rather than singular specialization.

[INSERT FIGURE 6 HERE]

The World’s Classroom

Today’s archaic model of higher education is perpetuated by a momentum that reinforces, among other things, traditional academic boundaries and limited scope. In the same way that disciplinary silos have eroded and academia has begun taking advantage of productive commingling, so too can its barriers to access be eliminated, allowing diverse points of entry (or, rendering moot the question of ‘points of entry’). Network-enabled tools will expand by orders of magnitude an education system that is currently not scalable. Established universities such as Yale, Harvard and MIT, as well as independent companies, are beginning to offer courses online. In a process of reverse-osmosis, education has begun to shift away from selective admission and turn outward to reach anyone and everyone with Internet access and an inclination to learn. A new model of academia could digitally recreate the collaborative, energetic experience of universities and disseminate it on a global scale. This education format responds to the needs of individual communities, particularly in developing countries, owing to its immediate response time and topical relevance. With these tools, the education gap would shrink and anyone – not just full-time students – would have the opportunity to learn. Intellectual potential could no longer go undiscovered.

[INSERT FIGURE 7 HERE]

The Factory Next Door

The word fabrication conjures an image of bleak Industrial Era factories where workers bound to production lines churn out endless identical objects. Tomorrow’s fabrication will be the opposite. Just as education is increasingly streamed to personal screens around the world (rather than demanding physical relocation to academic hubs) small-scale, local, and even in-home production would enable personal best-fit design. Focused on innovation rather than volume, a new economy of ‘downloadable’ objects is shared, modified and brought into physical space with dimensional printers. "Biomass and infomass are intersected, in some effective combination… where physical actions invoke computational processes, and where computational processes manifest themselves physically."24 As the same forces that enabled Open Source Software are applied to fabrication, the shift toward digital and local production will constitute a 3rd Industrial Revolution – a trend that The Economist Magazine elaborated in its April 2012 cover story.25 And on a scale larger than individual products, architectural construction itself can become iterative and dynamic through similar means. A more flexible design process might encourage an ecosystem of digital tools for the continual input and feedback of

23 Whitfield, John. “Collaboration: Group Theory,” Nature Magazine, issue 455. 08 October 2008. 24 Mitchell, William. 2000. 25 Gordon, Robert. “A Third Industrial Revolution.” The Economist. 21 April 2012.

various stakeholders. Static construction documents could be replaced by sophisticated systems that encompass each step in the process of design, materials sourcing, fabrication and assembly. When networked computers become a comprehensive tool for both design and construction, their feedback loops will allow components to be engineered, fabricated, adjusted and assembled on-site and in real time: the formerly distinct phases of building conception and construction are blurred into one.

[INSERT FIGURE 8 HERE]

Penniless Economies Many of these new urban dimensions enable (or are enabled by) atomized mobile technology, but this does not imply a decentralized and disconnected future without social cohesion. A new connected energy is at the crux of a redefined sharing economy: it is social and local. New economies are less about quantifiable, financial, extrinsic gains and more about social connectivity on the order of reputation, lifestyle and community building. It is well known that human action depends on rewards – financial and/or interpersonal – yet collective economies emerge as a response to both. This turns Veblen’s theory of Conspicuous Consumption 26 upside down, through a no-less socially driven Conspicuous Collectivity, hinging upon the powerful non-monetary reward of a person’s standing within the collective. Individuals seek a human scale to the networks at their fingertips – and a physical, interactive instantiation of the same – which will draw a critical mass of participants into sociable economies. Vibrant ties within an active community are crucial; constituting an intuitive network that reflects humans’ ingrained need for connection.

[INSERT FIGURE 9 HERE]

Hacking the City Virtual-physical systems, operating from transportation to economics, enable citizens to come together as actors in the context of the city. As bits and atoms become increasingly intertwined, any action on the digital side will have repercussions in the physical city (and vice versa): through their reciprocal enmeshing, the digital and physical can, and must, work together for citizens to enact metropolitan solutions. Given such hybrid tools, space can be thought of as a new, programmable interface – the city is an open-ended venue for engaged citizens to play by design. What Linus Torvalds did for open source software by sharing the “kernel” of an operating system can just as well spawn a culture of hackers in physical space. ‘Urban code’ no longer means zoning, but instead signifies ‘software code’ and ‘genetic code,’ both carrying implications of accelerated replication, mutation and distributed collective action. Digitally-controlled physical actuators like arduinos, fab-labs, and smartphones are already allowing anyone to manipulate their environment in the same way as they have been able to tweak and upload software. “Multi-layered manipulative platforms that integrate digital and physical representations will have a significant impact on urban design and planning processes in the future. The usefulness of these platforms will be in their ability to combine and update digital and

tangible data in seamless ways to enhance the design process...” 27 Smart cities and technologies can provide a networked metropolitan nervous system, but urban hackers will be the muscles that effect kinetic spatial transformations in urban space.

4. Conclusion

None of these dimensions could exist as exclusively digital or physical: they thrive at the intersection of bits and atoms. At the dawn of the Information Age it seemed that networked information space was the portent of a future without cities, yet growing and decisive trends prove the opposite. The smart city of tomorrow – the human and ultimately sustainable smart city – is predicated on a tightly meshed hybrid space. Yet as much as this digital integration provokes genuinely new relationships and modes of habitation, it nonetheless reinforces age-old human proclivities. As technology continues to dematerialize and permeate the physical environment – essentially, to disappear – it is foregrounded by the non-digital aspects of life: community, aesthetics, and nurturing environments. The value of a ubiquitous digital overlay, and of each trend identified in this chapter, will be proven in its capacity to achieve a meaningful sociability and productivity for humans inhabiting digitalized physical space. Dimensions of the sustainable future city will place emphasis not on smart cities but on smart citizens.

Figure 2. An analysis of the number of mobile phone calls made in Washington D.C. on Obama's Inauguration Day, showing peaks of call activity as the crowd anticipates the oath (2-3x avg call volume), a drop in call activity as the crowd listens to his inaugural address, and peaks again as the crowd celebrates the inauguration of the new President (5x avg call density).

Figure 3. In the Information Age, the flow of Internet traffic between locations is nearly ubiquitous. This project visualizes the volumes of Internet data flowing between New York and cities around the world over a 24 hour period. The size of the glow on a particular city location corresponds to the amount of IP traffic flowing between that place and New York City.

Figure 5. Local Warming is a prototype that tracks people's motion and directs a targeted beam of infrared energy - so they can be comfortably warm in an otherwise cold environment - and thus eliminating the inefficiencies of ambient heating all together. Warming explores a vision for the future of heating systems, suggesting highly efficient, dynamic and intelligent transmission of warmth.

Figure 9. The Cloud is based on a new form of observation deck, connecting visitors to both the whole of London and the whole of the world, immersing them in euphoric gusts of weather and digital data. Each individual footstep on the ascent to the Cloud participates in a vast collective energy-harvesting effort. Everyone around the world can contribute to the Cloud – whether by visiting or by sponsoring a LED and helping to keep the London lamp aflame. carlorattiassociati | walter nicolino & carlo ratti with Alex Haw and Atmos Team: Carlo Ratti, Giovanni de Niederhausern. http://www.carloratti.com/project/the-cloud-2/
