“The inhabitants of a city, it is true, must always ultimately derive their subsistence, and the
whole materials and means of their industry from the country. But those of a city, situated
near either the seacoast or the banks of a navigable river are not necessarily confined to
derive them from the country in the neighbourhood. They have a much wider range, and may
draw them from the most remote corners of the world, either in exchange for the
manufactured produce of their own industry, or by performing the office of carriers between
distant countries, and exchanging the produce of one for that of another. A city might in this
manner grow up to great wealth and splendour, while not only the country in its
neighbourhood, but all those to which it traded, were in poverty and wretchedness.” (Adam
Smith, The Wealth of Nations, 1776, p. 406).
Abstract
The geography of our planet shows increasingly an urban orientation. Cities or urban
agglomerations have a great variety of advantages, but exhibit also negative externalities.
This paper seeks to highlight the research challenges inherent in an urbanised world.
Particular attention is given to the solution potential offered by ‘smart cities’. The paper
concludes with lessons for urban governance.
Keywords: smart cities, urban governance

1. Emergence of the ‘Urban Century’
Human settlement patterns have over the past century shown a trend towards urbanised ways
of living. This is clearly mirrored in the urbanisation degree of most OECD countries, which
nowadays amounts to approx. 70 percent. The fastest growth in urbanisation however, takes
place in emerging economies and developing countries, so that it is foreseeable that our
planet will turn into an urbanised planet by the middle of this century. Mankind tends to
Karima Kourtit, Peter Nijkamp – Cities of the future: research challenges in the ‘urban century’

become an urban species. Urban agglomerations will then likely act as technological, social,
economic and political powerhouses and will become key actors for sustainable development
of our urban world.
The current urbanisation trend is a global phenomenon. But the structure of
urbanisation shows quite some variation in different regions of the world. For example,
despite the fact that the urbanisation degree in Europe does not show significant differences
from the USA, about 7 percent of the population in Europe lives in cities of over 5 mln, as
opposed to 25 percent in the USA (see Brown 2010). Both continents exhibit an urbanized
settlement pattern, but this pattern is less concentrated in Europe and has more mixed urban-
rural features than the USA. It is fair to say that the USA is showing a trend from
urbanisation to metropolitanisation, in which urban sprawl has an intermediate place. On the
contrary, the urbanized geography of Europe exhibits more a pattern of a mutually connected
urban network in which dense infrastructure (roads, railways, airline connections) plays a
central role.
Despite rural features in isolated areas, most OECD countries may be regarded as
urbanized regions. The transitional areas between rural and urban areas are sometimes called
‘rurban areas’. They are characterized by a great variety of appearances and functions (see
also Bengs and Zonneveld 2002, Bryant and Charvet 2005, Buciega et al. 2009, and Rauws
and de Roo 2011). Usually, they have an orientation towards larger agglomerations, are
relatively small in population size and have often a high ecological quality that is favourable
for leisure activities (see also Hoggart 2005, and McDonagh 2009). These ‘rurban’ areas are
apparently the result of urban growth and related urban agglomeration advantages as main
drivers.
Clearly, modern urban areas are also faced with far-reaching challenges, such as an
unprecedented influx of foreign migrants, an ageing population, urban sprawl, socio-
economic disparities, decline in social cohesion, rise in segregation, mounting volumes of
traffic, environmental degradation, rising resource use, and threatening human health
conditions. The shadow side of current urbanisation embodies high social costs. The dangers
of uncontrolled urbanisation have been clearly recognized in Europe, witness the emergence
of the Joint Programming Initiative (JPI) ‘Urban Europe’†, which has made a successful
attempt to mobilize the research forces in Europe in order to cope with the urban challenges
and issues.

Urban agglomerations are however, not only a source of decay and disaster, since
they can fortunately also act as a source of progress and new pathways (see e.g. Kourtit
2014a,b; Nijkamp and Kourtit 2013). Urban agglomerations may act as vehicles to turn
threats into promising opportunities, inter alia by exploiting local resources to create
sustainable growth (including a resilient and inclusive local economy), by enhancing the
potential of socio-economic, cultural, ecological and demographic diversity, by combating
spatial exclusion and energy scarcity with better housing, by shaping appropriate conditions
for a green and healthy locality, by seeking to achieve a balanced population development at
the edge of urbanity and rurality, and by creating attractive open public spaces in urban areas
with a ‘colour locale’ (see also EU 2011).
It is noteworthy that in the history of mankind urban areas have always prompted a
complex array of policy and research questions. About half a century ago, a unique gathering
took place of urbanists, nowadays knows as the Delos Symposium (July 1963). They shared a
common concern on the urban future of our world. In their Newsletter issued by Doxiadis
(1963) the following statement on the emerging challenges of our world was made: “when we
place all these extraordinary achievements together, however we can see where we have
failed: by bringing together all the elements of progress into a meaningless and inhuman
system of life.” (item 4, p. 21). The complex urban history and urban policy development
can in the long history of cities all over the world be characterized as a process of
‘challenge and response’ (see Kourtit 2014a,b), which is essentially based on a learning
paradigm for all actors involved in the life course of cities.
Cities all over the world have never been static, but always in a state of flux, by
accommodating themselves to new opportunities and coping with threats and challenges. The
rise of modern cities – leading to metropolitan areas and megacities finds its origin in
economies of density, synergy advantages and open network constellations. All these forces –
positive and negative – have led to a structural dynamics of urban areas. Thus, urban
transformation is a common feature of all cities which survived in the long history of spatial
dynamics in our world. This resilience of cities also means that technological, social and
institutional innovation is a prerequisite for the structural performance of cities. This is
clearly reflected in the current ‘smart city’ initiatives, which seek to combine the benefits of
urban density with the advantages of ecological quality (‘the quality of place’). Modern cities
are essentially ‘multi-tasking’ agents comprising a wide variety of stakeholders with different
interests. Strategic forward thinking and acting is therefore, a necessity for ‘urban survival’
(the ‘Prometheus governance model’) and resilience (see also Vanolo 2014).

Such ‘smart cities’ should not only create the conditions for enhanced and accelerated
growth (due to ICT, R&D, education, creative sector initiatives etc.), but also offer a solid
contribution to sustainable city development (based on initiatives favouring green cities, eco-
cities, climate-neutral cities, zero-emission cities, liveable cities, resourceful cities etc). The
nature of urban planning will dramatically change in the future and calls for new and
unconventional policy departures, such as the design of agri-cities, urban planning with
nature, development of urban landscape ecology, design of green urban networks, or
integrated development of urban brownfields and greenfields. The challenges for planning
and research in the ‘urban century’ are vast, complex and far-reaching.
The present contribution aims to sketch out the most prominent challenges in the
urban domain. It will do so by presenting the main findings from an exploratory study on
urban megatrends, which provided the cornerstones for the development of a European
research agenda in this field. The new opportunities provided by the current wave of ‘smart
city’ initiatives will next be explored, with particular emphasis on the research and policy
opportunities offered by digital technology and ICT (in particular, ‘Big Data’). The paper
will be concluded with a sketch of governance issues involved.
2. Research Challenges of Urbanisation
The history of mankind over the past millennia is mainly a rural history. Clearly, urban
settlements did exist already a few millennia back, but most of these settlements were
relatively small in size and were not dominating the geography of the world. A few cities
managed to get much political power (Babylon, Nineveh, Rome, e.g.) and were seen as
global power players, even though their population size was not impressive compared to
current standards. Only the last few centuries marked the rise of an urbanized pattern of life, a
process that is even accelerated in emerging and developing countries (Latin-America,
Africa, Asia). If the global future is going to be an urban future, a thorough analysis of trends,
bottlenecks, policy tasks and research needs on cities and city networks is pertinent (see
Taylor 2003). This task has been undertaken by the Scientific Advisory Board of the Joint
Programming Initiative (JPI) ‘Urban Europe’ (see Coutard et al. 2014). In their recent
scoping document they map out various mega-trends, ranging from global to local, with a
view to the identification of policy challenges and research requirements in the urban field.
The JPI findings are presented in a cascade form, starting off from global tendencies and then
moving gradually down to local issues.

From a global perspective, a series of structural trend developments are distinguished
which seem to be rather robust in the decades to come. These trends all point towards a
decline in rural areas and a rise in urban areas. The following issues are noteworthy:
Globalised economy
The world-wide scale and depth of interconnections and interdependencies have
increased rapidly, with a rise in cross-border trade towards intercontinental linkages,
in which multinational companies play a prominent role. The rise of large
agglomerations and megacities even in the form of city networks has run parallel
to the globalisation trend.
Geopolitics and conflict
The period after WW II has seen the rise of many independent nation states, in
combination with multi-scalar systems of institutions and organizations,
intergovernmental bodies, supra-national bodies and (inter)national NGOs. Much
political power is nowadays concentrated in urban areas and agglomerations, so that
urban agglomerations have become engines of political power.
Demographic change
The rise in population – despite the ageing trend in most OECD countries leads
most likely to a world population of about 10 bln people by the middle of this century.
Most of these people will live in cities, with the consequence that the rise in the
number of cities will grow exponentially, while the large cities will grow into mega-
cities, with more than 10 mln inhabitants.
Social inequalities
Cities have often been economic resorts to escape from poverty. But in recent times,
cities have become places where social inequalities and disparities in the standard of
living have increased. This does not only hold for income or employment, but also for
education and health.
Global environmental change
The population rise, the growth in welfare and in mobility, and the needs of many
people in less privileged countries have meant a formidable threat to sustainable
development (e.g., environmental quality, energy savings). Cities – through their scale
and agglomeration advantages are able to provide efficient technological measures
and behavioural incentives for environmentally-benign and energy-saving strategies.
Urbanisation
Karima Kourtit, Peter Nijkamp – Cities of the future: research challenges in the ‘urban century’
7
Cities are sources of economic, social, ecological and technological opportunities. In
this way, they may act as self-perpetuating engines attracting even more people. This
prompts the need for effective and balanced policy strategies on urbanisation in the
‘urban century’.
Next, from a European perspective, also a wide variety of concerns and challenges
can be distinguished. Europe is a rather urbanized continent. Even though the population
growth is modest to almost zero, European cities are vulnerable, given their architectural and
cultural heritage. The following challenges can be mentioned:
Economic development
The economies in the European countries have shown a high degree of dynamics in
the past decades, with dramatic shifts in labour markets, technological developments
and R&D orientation. The EU has become an open trade region, an open job market,
and partly an open monetary system (the Eurozone). Cities in Europe have
strengthened their position as leading economic, knowledge and technological hubs.
Governance and government
Europe has not only seen the rise of many independent nation states over the past
decades, but also the emergence of supra-national bodies. Clearly, this was
accompanied by many tensions, especially in the Central and South-Eastern part of
Europe. European cohesion policies have been put in place in order to mitigate the
emergence of strong socio-political tensions in Europe. Governance systems in
Europe are extremely complex, but they have been instrumental in shaping the wider
political landscape and geography of Europe.
Demographic change
Europe has a rather stable – and in some countries, even a declining population. The
relatively high welfare standards in several European countries attracts many
migrants, partly from inside Europe (in particular, Eastern European countries), partly
from Africa and Asia (including the Middle East). As a consequence, cultural
diversity in European cities is rapidly rising. Together with ageing processes, this
leads to an unprecedented population diversity in many cities in Europe.
Climate change mitigation and adaptation
Karima Kourtit, Peter Nijkamp – Cities of the future: research challenges in the ‘urban century’
8
Maintenance and improvement of urban environmental quality conditions are a sine
qua non for any city. This is also reflected in a great variety of climate strategies and
targets for European cities. This does not only hold for air pollution control or noise,
but also for water management and safety.
Urbanisation
As mentioned before, the density of medium-sized cities in Europe is rather high; they
are often connected through well-developed infrastructure. The urban landscape is
diverse and tends to be stretched out towards rural or semi-urban areas, sometimes
even leading to polycentric urban development. At the same time, there is a tendency
towards smart growth in compact cities. The European urban landscape exhibits
indeed a great diversification.
Transport
Transportation systems in Europe act as the blood circulation of geography. Such
systems need a high degree of accessibility and connectivity so as to offer an
integrating infrastructure for the European space-economy. At the same time leads an
intensification of transport flows (persons, goods) to environmental decay and lack of
safety. Such negative externalities are mainly concentrated in urban agglomerations.
Clearly, cities are action spaces for benefits, but also for threats in a modern network
society.
In the third place, the internal city functioning has to be addressed. Cities are
complex, multi-tasking systems, with a high degree of metabolism and nonlinear dynamic
evolution. The following elements are mentioned as challenging issues:
Spatial dynamics
From an economic, social, demographic and technological perspective, cities are
adaptive systems, with a high degree of evolutionary dynamics. There are many self-
organising forces in urban areas, which may reflect resilience, but also serious decays
due to vulnerability may occur.
Metabolism
Cities are dynamic physical entities that are subjected to the laws of physics
(including entropy). They may be out of equilibrium, as a result of an exogenous
impulse. Consequently, resource management under conditions of city metabolism is
of critical importance for the sustainable development of cities.
Karima Kourtit, Peter Nijkamp – Cities of the future: research challenges in the ‘urban century’

Infrastructures and smart cities
Infrastructure is the spine of a city or of a system of cities. The cities’ social,
economic, technological and political performance is depending on reliable, robust
and efficient infrastructure. In this context, the notion of a ‘smart city’ is relevant, as
this refers to ‘doing things better’ through the use of knowledge and technology.
Clearly, digital technology in smart cities plays a central role in achieving such goals
(see also Section 3).
Social tensions, welfare and inequality
Modern cities are always in a stage of transition. This holds for the economy, for the
population composition, for the labour market and for the housing market. Such
developments induce social tension and social exclusion, and lead eventually to
segregation.
Cultural heritage and tourism
European cities have mostly a long history and consequently, a wealth of
architectural, cultural and political heritage. Any change in a city may have
implications for the urban heritage, so that the free manoeuvre space in European
cities is normally restricted. Balanced urban growth is certainly a great challenge in
Europe.
Urban governance and planning processes
Urban planning is normally a sine qua non for a balanced development of cities.
Planning traditions and practices – especially regarding land use vary widely all
over Europe, ranging from top-down to participatory modes, depending also on the
size and scope of the plan concerned. Governance systems for cities differ, therefore,
significantly as well, although in many cities sustainable development has been
agreed upon as a major overarching policy objective.
On the basis of the cascade of global, European and urban challenges and concerns,
the JPI report argues that the world is becoming more populous, with more economic
dynamism, but also with more ecological threats. Cities play a central role in this
development, as they are the source of higher productivity, efficiency and ecological quality,
but at the same time also the source of socio-political stress and segregation. European cities
have to find a balance between mutually contrasting forces, with a view to a long-range
sustainability. Research in the urban field – from a future perspective needs to be broadly
Karima Kourtit, Peter Nijkamp – Cities of the future: research challenges in the ‘urban century’
10
conceived in nature, but also to find meaningful anchor points in basic knowledge on cities
and their evolution. This also calls for rich empirical datasets, bridges to applied useful
methodologies, planning solutions and effective policy instruments. There is indeed a need to
proactively address the great many challenges and threats faced by cities. In its concluding
framework section for ‘Urban Europe’ research, the JPI report (see Coutard et al. 2014)
claims: “What is clear is that an approach is required that possesses a number of qualities that
enables a holistic yet nuanced understanding to be developed and contextual and relational
responses to be delivered. Neither a silo approach to each issue or case, nor a one size fits all
theory or policy, will produce the interdisciplinary, integrative, pluralistic, nuanced and
contextual knowledge needed to understand and manage contemporary urbanism and
urbanisation. And given the pressing nature of the challenges and problems facing cities, it is
not enough to simply produce new knowledge through research; rather such fundamental
knowledge needs to be translated into utilisable techniques and technologies and instrumental
policy and action”.
3. The Nature of ‘Smart Cities’
Urban agglomerations are no passive spatial entities. They contribute actively to the
well-being of the local population, but also to all those who are directly or indirectly
connected with the city concerned. The spatial footprint – or action radius of a city may
range from the direct hinterland to the planet as a whole. Governing such socio-economic and
technological potential calls for an urban intelligence that is able to cope with the wide
variety of challenges sketched out in Section 2. This mission leads to the popularity of the
current ‘smart city’ movement, as cities are forced to be competitive amongst each other,
with the goal to offer the highest quality of urban life, the best possible opportunities for
business life, and the most favourable ecological conditions (the so-called XXQ principle; see
Nijkamp 2008). There is a wide diversity of definitions of a ‘smart city’, but in most
definitions a ‘smart city’ is regarded as an urban agglomeration that seeks to accomplish a
better socio-economic, technological and ecological performance of a city through the use of
ICT, in particular the use of digital technology (in other words, a kind of e-city; see
Townsend 2013). This calls for an appropriate and integrated combination of human capital,
social capital, creative capital and infrastructure capital. These are the seedbed conditions for
innovativeness, entrepreneurship and economic growth. Smart city policy is essentially based
on intelligent resource management through information technology, with a view to ‘doing
things better’.
Karima Kourtit, Peter Nijkamp – Cities of the future: research challenges in the ‘urban century’
11
The ‘smart city’ movement has over the past years witnessed a booming development,
often as a combination of public and private initiatives. There is a wealth of opportunities and
applications for ‘smart city’ actions at the level of cities or regions. A recent report by
Steenbruggen et al. (2015) offers a nice set of illustrative applications of ‘smart city’
application fields:
Logistic distribution of goods in cities
Establishment of smart urban energy grids
Monitoring of urban quality-of-life indicators
Intelligent 3-D planning of urban space
Pro-active management of water flows in cities
Design of driverless cars (pilots)
Innovative urban parking management
Creative forms of cyber safety in urban areas
Online retail initiatives (including distribution)
New forms of car sharing initiatives
Sensor systems for optimal matching between energy demand and renewable energy
supply
Electronic traffic incidence management
Integrated transport flows management in urban areas
Interactive living lab learning applications
Optimal coordination between private and public transport
Novel contributions to urban e-democracy
Tailor-made supply of care systems for elderly
E-safety in popular entertainment centres etc.
Clearly, to accomplish a fully integrated ‘smart city’ is not an easy task. An
illustration of a systematic scheme on the various stages of such an urban intelligence can be
found in Figure 1.
It should be added that a necessary element of a ‘smart city’ policy is the design and
operational use of the ‘Internet of Things’, and more in particular of ‘Big Data’ (see Kitchin
2014; Robinson 2011). Big Data are ‘mountains of data’ acquired through the medium of
digital technologies (sensors, camera’s, GSM, GPS, social media etc.), often on-line available
which offer a micro-based picture of objects and movements of objects. Such data are usually
Karima Kourtit, Peter Nijkamp – Cities of the future: research challenges in the ‘urban century’
12
characterized by 3-V: volume, velocity, variety (and sometimes veracity). Such large-scale
information flows with open access can be used for data exploration and description,
descriptive statistical analysis, predictive causal modelling, and retrieval by substance or
content. In recent years, big geo-data have become rather popular management tools for
space-time problems in urban areas (e.g., traffic management). Such spatial data-analytics
operate often at the interface of virtual and real worlds.
It seems plausible that ‘smart city’ initiatives in combination with e-services provided
by the ‘Internet of Things’ will show a booming growth in the years to come. This will be
facilitated by new advances in ‘Big Data’ management and analysis, as is witnessed by the
recent progress in the field of data mining techniques.

4. In Search of the ‘City Captain’
Cities have turned into excessively complex spatial entities. In the previous sections
various challenges and threats to this vulnerable human ecosystem have been indicated, in
particular, the stimulation of economic vitality, the mitigation of social exclusion and
fragmentation, the maximization of ecological quality and sustainability (including energy
use), the management of a balanced mobility of the urban population on the basis of
accessibility and connectivity, and the protection of architectural and historical cultural
heritage in the city. All these policy concerns have to be placed in the context of
contemporaneous urban dynamics, with its different spatial land-use manifestations, such as
urban expansion, suburbanisation, urban sprawl, edge city developments, and trends towards
poly-nuclear urban systems. But who is the responsible captain for such a dynamic evolution
of cities?
The European urban system has a particular precious feature, namely a wealth of
heritage assets. They form a diversified collection of architectural and artistic goods that
attract millions of tourists from all over the world. By exploiting the benefits offered by the
past heritage, local vitalization and socio-economic resurrection of agglomerations is
favoured. Thus, culture-led regeneration of cities is an additional challenge and a new
opportunity for many cities in Europe. Such a policy does not only refer to tangible assets
(e.g., museums, churches, castles, festivals, arts exhibitions and the like), but also to cultural
events or sports manifestations. Consequently, city branding is increasingly becoming a
major policy instrument for boosting the attractiveness of a city through the creation of an
appropriate city image. Such a strategy is also in agreement with current initiatives to favour
creative classes in creative urban districts (see Kourtit et al. 2014). Next to local cultural
policy stimuli, there are also European actions favouring urban culture as a prominent
cornerstone for urban Europe, such as: the European Heritage Days, the European Heritage
Label, and the establishment of the European Capital of Culture programme.
It is obvious that historical culture is by far not the only concern of urban policy-
makers and planners. The EU report on ‘Cities of Tomorrow’ (2011) offers a whole range of
foreseeable future developments of cities, of hurdles and threats to a balanced urban
evolution, of new chances to turn problems and bottlenecks into opportunities, and of new
forms of governance to respond to these urban challenges. These items will concisely be
presented here.
Cities are critical for a sustainable EU development
Karima Kourtit, Peter Nijkamp – Cities of the future: research challenges in the ‘urban century’
14
The strategic future role of cities in Europe originates from the following observed
trends: Europe is highly urbanised; cities are logistic, innovative and socio-economic
engines of the EU; urban dynamics exceeds the city borders and calls for new forms
of flexible governance of cities; cities are fireplaces for education, health, social
cohesion, culture, ecological regeneration, and democracy; urban agglomerations are
the anchor points for a balanced territorial development of Europe.
The current urban development in Europe does not contribute to sustainable
development
Various threats can be distinguished: demographic change causing ageing in cities
and shrinkage of cities; disruption of economic growth perspectives, in particular in
older industrial cities; high unemployment levels (especially among the youth) in
many cities; rise in socio-economic disparities in European cities; an increase in social
polarisation and segregation causing more marginalised groups; an increase in social
tensions and hostile attitudes in various urban districts; increasing negative spatial
externalities due to urban sprawl and uncontrolled land use in urban areas; threatening
development of urban ecosystems, biodiversity and water resources.
Europe has many opportunities to turn threats into positive challenges
Urban development in Europe has also many possibilities for a sunny perspective, in
particular: global competitiveness of cities can be combined with sustainable local
economies; European cities have the potential to create a resilient and inclusive
economy; socio-economic, cultural, generational and ethnic diversity may be used as
a source of innovation; eco-friendly initiatives may be combined with better housing
conditions; cities in Europe offer a great potential for a holistic approach to
environmental and energy issues; medium-sized cities in Europe may be instrumental
in avoiding rural depopulation; sustainable cities in Europe may offer favourable
public transport so as to reduce car mobility and to create attractive open public
spaces.
Europe needs adaptive governance systems to cope with the new urban challenges
The policy challenges for European cities are vast and call for new forms of
governing complex urban development in the ‘urban century’. The following
signposts can be mentioned: cities of tomorrow need a holistic model of sustainable
urban development matching place-based and people-based approaches; urban polices
need to be flexible and to take into account various territorial and temporal scales;
Karima Kourtit, Peter Nijkamp – Cities of the future: research challenges in the ‘urban century’
15
urban development needs a multi-faceted (‘across sectors’) approach; urban
governance systems have to be based on horizontal and vertical coordination
mechanisms at different territorial scales; participatory governance modes including
all relevant stakeholders are to be put in place; social innovation in urban
agglomerations should favour civic engagement, creativity, and cohesion; cities in
Europe need professional foresight systems to anticipate conflicts, to mitigate
contradictions and to better understand urban complexities.
The above perspectives on cities of the future highlight that a careful governance of
urban systems is needed. The complexity of modern cities makes them vulnerable; managing
such fragile human ecosystems concentrated in a small territory poses many questions on the
geographic span of control of urban governance, on the competences of various stakeholders
involved, on the time frame of urban policies, and on the long-run information needs for
balanced urban planning. ‘Big Data’ handling and organisation is a sine qua non for
sustainable city governance in the future. From this perspective, the current ‘smart city’
movement is promising, provided it is supported by smart forward-looking urban research.
