2.2. Diagnosis: economic development and competitiveness under threat Europe is no longer in a situation of continuous economic and demographic growth. The decline or disappearance of traditional manufacturing industries has led to the loss of skilled manufacturing jobs and a mismatch between labour market supply and demand. With increasing immigration and mobility, pressures on national welfare systems and more vulnerable labour markets, European cities face increasing social and economic polarisation, both within and between them. The recent financial and economic crisis – whose negative effects have yet to completely unfold – has left many European cities in a poor state, accelerating the polarisation process and putting the European urban development model to the test. 2.2.1. Europeancitiesfollowverydifferent developmenttrajectories The economic development of a city is highly pathdependent and is affected very much by its previous history of economic specialisation and institutional development. Each European city follows its own individual development trajectory. These trajectories can be more or less sensitive to external influences and shocks – depending on cities’ resilience and resistance to external events – and are also altered by public policy interventions. The diversity of European cities in terms of size, demographic mix, as well as economic, social and cultural heritage, gives them very different possibilities for changing their development trajectory. However, as competition increases, cities have tried to improve their respective position by developing and attracting economic activities by establishing strategic visions, endeavouring to involve key economic players, improving the quality of life for professionals, and developing centres of creativity, etc. 51 According to an expert commission set up in December 2008 by the German Association for Housing, Urban and Spatial Development – supported by the Federal Ministry of Transport, Building and Urban Development. 52 ESPON FOCI Final Scientific Report, Chapter 2, op.cit. Cities of tomorrow -Challenges, visions, ways forward Nevertheless, many studies have shown that the economic growth of cities is frequently embedded in national economic systems and is often strongly related to the development of the latter. Seventy-four per cent of the differences in growth (in GDP) between individual cities in Europe is accounted for by differences between the growth rates of different countries, and just twenty-six per cent by the differences between growth rates of cities in the same country.53 There is, however, a marked difference between large cities’ growth in EU-12 and EU-15. The largest cities in EU-15 Member States grew marginally faster than cities as a whole within their countries in the period 1995-2001 and grew at about the same rate in the 2001-06 period. However, the largest cities in the EU-12 Member States grew significantly faster in both periods.54 2.2.2. Askill base under threat The evolution of the vast majority of European cities’ skill bases has been dependent on the changing organisation of industrial production and the increasing service content of both inputs and outputs, ranging from research and development to maintenance, much of which relies on a qualified workforce. The loss of manufacturing jobs has not only reduced the demand for low-skilled labour, but also affected demand for high-skilled jobs. A considerable portion of the high-level services that cities have tried to develop in recent decades has been related to the financial sector, including the legal and accounting services that feed into it. The financial sector has been considered a key part of the knowledge economy, but its utility for economies as a whole has been increasingly called into question by the financial and economic crisis. The loss of manufacturing jobs is difficult to compensate with the creation of new, more highly skilled and competitive jobs. The transition to a more qualified labour force is difficult, as the low-skilled unemployed, especially the long-term unemployed, face serious difficulties in upgrading their skills and reintegrating into the labour market. Moreover, the present growth model, with its decoupling of economic growth from employment, has led to a larger share of the population being either pushed out of the labour market or having to accept low-wage jobs in the non-qualified service sectors. For instance, the evolution of jobs in Belgium between 1991 and 2001 shows a net gain of skilled jobs of around nearly 60 000, but these new jobs are outweighed by the massive loss of 230 000 manual jobs. Cities like Liege and Charleroi have experienced net losses in both categories of jobs, although the proportion of skilled jobs has increased.55 The public sector in many European countries is reducing budgets through direct layoffs and increased reliance on the private sector. In some cities with a high proportion of public sector jobs, this may cause serious problems if there is no private sector demand. 53 ESPON–FOCI, final report, p. 44; GDP is measured in purchasing power standard. 54 ESPON–FOCI final report, pp. 44–5. 55 Van Hamme, Gilles, Wertz, Isaline and Biot, Valérie, ‘Economic growth devoid of social progress: the situation in Brussels’ in Brussels Studies (www.brusselsstudies.be) issue 48, 28 March 2011.

GLIWICE – Using regional funds to support local SMEs and economic revitalisation of the city With 192000 inhabitants, Gliwice is the second largest city in the Upper Silesian industrial region, one of the main industrial zones of Poland. Following the initial difficult years of political and institutional restructuring following transition towards market economy, Gliwice managed to turn things around and today is in a strong position. It has managed to attract large companies to the area, including Opel, NGK Ceramics, Mecalux and Roca. However, support is also vital for SMEs, representing 99% of enterprises in Gliwice, and knowledge-based activities, notably the Technical University and research centres. The municipality, its agencies (Local Development Agency, NGO centre), the Silesian Association of Support for Enterprises and other bodies (Technology Park, Chamber of Commerce, etc.) are working together to ensure this support continues. Their activities focus on training and advisory programmes for target groups (unemployed, NGOs, young people, etc.) and also physical investment projects (abandoned mine reconstruction, Technology Park construction, etc.). As an example of a city that relies heavily on EU funds, Gliwice illustrates the various sides of this funding. The general aim of the city – to address the priorities and demands established by the EU – tends to favour standardised projects rather than tailored projects based on local assessments. Thus, close coordination in areas such as programme monitoring and impact analysis is needed at city level. Cities of tomorrow -Challenges, visions, ways forward 2.2.3. Cities facing the crisis The volatility of international business – as harshly experienced by many cities during the crisis – makes cities that strongly rely on foreign direct investment vulnerable to changes in international competition. The same goes for cities dependant on single sectors, especially traditional manufacturing or rawmaterial- based industries. Among the most vulnerable are those cities dependent on a mono-sector manufacturing base in decline. They are challenged by a need to restructure and diversify their economic base while facing out-migration and a loss of financial capacity. Delocalisation of manufacturing has led to a loss of skilled jobs and the destruction of human capital – a negative spiral trajectory. Outsourcing of the manufacturing of specific components has had similar negative consequences, with a loss of tacit production knowledge and the replacement of skilled production work by low-skilled assembly work.56 Many cities, especially in Central and Eastern European countries, including the former East Germany, started experiencing delocalisation and shrinking populations in the mid-1990s. Increasing pressure on European cities brought by globalisation and European integration in the past two decades has led to a polarisation of urban performance, which has been aggravated by the enlargement process. Central and Eastern European cities have faced the additional challenge of increased competition while radically transforming their economies and their economies’ institutional foundations. This adjustment process is proving extremely difficult, especially for cities not benefitting from foreign direct investments. The ensuing significant decrease of public finance has led to emergency situations in many of these cities, with decaying infrastructure, high unemployment, deserted inner areas and growing segregation.

It may be that we have not yet seen the worst of the crisis in many of those cities, as many cities’ economies rely heavily on the manufacturing sector, which has been one of the worst hit by the crisis (see Fig. 1 on previous page).57 2.2.4. Competitionasazero-sum game Links between cities in Europe are considerably more extensive than those on other continents.58 Over the past few decades, cities in Europe have generally developed together and when they have fallen into crisis, they have done so briefly. In the future, due to increasing competition, it appears likely that there will be not only winners, but a considerable number of losers who will fall into a more fundamental crisis due to the cumulative causation involved. Competition between cities in attracting firms or highly skilled individuals can also be a zero-or negative-sum game, in which cities compete for finite human and monetary resources within the European space by undercutting each other. A low-tax strategy may not only reduce capacities to improve infrastructure, develop high- quality public services and improve living conditions for the city itself, but also undermine nearby cities’ fiscal policies. Overly expansive policies aimed at attracting investments or human resources may only be partly successful because of nearby competition, and fail to generate enough outcomes to be sustainable over a longer period. 2.3. Diagnosis: a growing social polarisation European cities have traditionally been characterised by less segregation and less social and spatial polarisation compared to, for instance, US cities. This has been especially true for cities in countries with strong welfare systems. However, there are many signs that polarisation and segregation are increasing. The economic crisis has further amplified the effects of globalisation and the gradual retreat of the welfare state in most European countries. Although average living standards have increased over time, there are signs not only of growing income disparities but also of the poor getting poorer. In some places, local populations suffer from a concentration of inequalities: poor housing, low-quality education, unemployment, and difficulties or inabilities to access some services (health, transport, ICT). Reduced public finances in many cities have led to restricted cyclical policies which aggravate these issues further. With fewer labour market opportunities, there is a risk of increasing intolerance and polarisation between those who contribute and those who benefit from social allocations. The situation is very varied in Europe, and some cities have been worse hit than others, not least the Central and Eastern European countries, in which political restructuring has led to new patterns of social and spatial segregation. The wealthier cities of Western Europe also face the challenge of rising segregation and polarisation. Based on data from the EU Survey on Income and Living Conditions (EU-SILC), it has been shown that there is a higher share of severely materially-deprived individuals in the urban population compared to the rest of the population in the EU-15 Member States (see Annex 1 – Chapter 2). In Belgium for instance, there is increased income inequality in cities and those with the lowest incomes are actually getting poorer.59 57 Calafati, Antonio, issue paper, Cities of tomorrow, Brussels, December 2010. 58 ESPON–FOCI, final report. 59 Source: IGEAT, Growth and Social Exclusion project for the Belgian Federal scientific policy, draft final report; cities are approximated by NUTS 3. Cities of tomorrow -Challenges, visions, ways forward AMSTERDAM – Rethinking diversity policy to strengthen social cohesion and tackle the risk of segregation Like most large European cities, Amsterdam is facing a social cohesion challenge. While other cities focus on the integration of migrants, Amsterdam is more open, dealing with all minorities equally, including migrants and other underprivileged or discriminated groups. Amsterdam has seen two migration flows in recent times: from former colonies, mainly Suriname, Antillean islands like Aruba, Curaçao, St Martin and the Moluccas, and from other countries; both driven by economic deprivation and/or political repression. National policies on ethnic minorities are seen as generally tolerant, Amsterdam being a flagship for these policies. But city authorities have now shifted from a ‘minority policy’ to ‘citizenship policy’ approach focused on dealing with individuals. One consequence is that people acting more independently of their ethnic group may weaken internal group cohesion. To address this and also the challenge of growing racism and xenophobia, the city authorities are promoting the participation of and cooperation with all inhabitants and taking action to de-legitimise and oppose racism and discrimination. The city of Amsterdam, more than any other Dutch city, has undertaken positive action in support of ethnic minorities, including immigrants from non-western countries and refugees. The action has included mechanisms aimed at recruiting non-Dutch people or Dutch people with foreign roots to work in public services (currently 22% of staff; with a new target of 27%). In this photo collage Fatima Elatik, the local councillor takes the floor. She is shown surrounded by the women, the 'regentesses', who controlled the municipal government in the XVIIth century. This is a reference to the spirit of Amsterdam's golden age, which is still very much alive in the city. Fatima Elatik is of Moroccan origin and highly active in the field of diversity policy. Polarisation is a question not only of rich and poor, but also of cultural, social and ethnic diversity. Globalisation has led to an accelerated circulation of people, commodities, capital, identities and images, as well as an increased mobility of ideologies, economic principles, policies and lifestyles. The widespread use of social ICT applications, e.g. Facebook, has given new meanings to space and place. There has been a shift from a class-based modern society to a fragmented postmodern urban society with many different groups living side by side, sometimes without interaction. The very concept of social cohesion is being put to the test by these developments. Simultaneously, there can be very strong cohesion within particular groups or communities in an urban setting, but intolerance and even violence between them. Such cohesion is constrictive, oppressive and exclusive, and it inhibits social mobility. Social cohesion must, therefore, be considered at different scales and territorial levels, and its possible negative elements must be understood and countered. It needs to be built on universal values, such as sharing public places and services, rather than historical values linked to national, religious or ethnic identities. In some situations, the poorest parts of the population have been left behind or been put at risk of lagging because of policies designed to increase the attractiveness of cities which focus on upgrading city centres, building new eco-neighbourhoods, business parks or shopping centres, thus increasing social and spatial segregation. One example is energy poverty; with rising energy prices, those most in need of energy efficiency investments are those that cannot afford them or cannot benefit from tax incentives. Accessibility to services, including public transport, as well as culture, also tend to be less developed in the least attractive parts of urban areas, aggravating the exclusion and isolation of the poorest. The increasing reliance on private initiatives and charitable organisations to alleviate poverty-related problems raises questions about transparency and democracy, as many of the organisations involved are faith-based or have their own political agenda. 2.3.1. Spatial segregation and housing Good housing conditions are key to making a city and its agglomeration attractive and liveable. However, in many cities, spatial segregation processes – as an effect of social polarisation – make it increasingly difficult for people with low incomes or from marginalised groups to find decent housing at affordable prices. In Romania for example, more than 900 000 people have between 3 and 3.5 square metres – the equivalent of one bed and half a table – to live on.60 Social integration strategies based on education and training may work in situations of relative poverty but do not function in such situations of extreme poverty and segregation: ‘it is impossible to learn mathematics in a nice school and go back to the shack, sharing the only bed with four other brothers’.61 Socio-economic and demographic trends have an impact on spatial settlement structures, which will exacerbate social polarisation, reinforcing links between specific socio-economic groups and specific housing conditions and locations. This is an issue not only for those living in precarious conditions but also for those facing either a decrease in their revenues or a strong increase in market prices for housing. They may include, for example, people who have lost their jobs, single parents, retired people, as well as an increasing number of young people due to the impact of the economic crisis on the job market. The gentrification of city centres and the rising cost of housing make it increasingly difficult for a number of people to find decent or affordable housing where they grew up. In France, the share of housing costs in household budgets has grown from 10% in 1960 to 30% in 2010, 60 Data drawn from the 2002 Census in Berescu, Catalin & Celac, Mariana, Housing and Extreme Poverty.

Cities of tomorrow -Challenges, visions, ways forward Socio-demographic evolutions in the Czech Republic between 1990 and 201062 The spatial imprint of social polarisation follows partly the spatial pattern of Western European city regions but with some specific features. The housing estates which accommodate a remarkably large percentage of the national population – 30% in the Czech Republic – have changed from mostly middle-class young family housing in the 1960s to 1980s, into residences for elderly people and, increasingly, for migrants and centralposhenclaves gatedsuburbanenclaves suburbansatellites compactcity&gardensuburbs housing estates dilapidatedexclusionenclaves Yellow field = migrants ; grey field = elderly Source: Maier, Karel, op. cit. other transitory populations. Exclusion enclaves have emerged, especially in old working-class districts and housing estates in declining old industrial regions. At the same time, gentrification is changing certain attractive historical cores as well as certain selected inner-city districts. The wealthy settle in upmarket inner city areas and suburban locations while the poor – including a majority of migrants and elderly people – increasingly settle in housing estates and dilapidated exclusion enclaves. RICH IN-BETWEENS? MIDDLECLASS? POOR and represents as much as 37% for newcomers to the housing market.63 In the period 1994–2005, housing costs in the EU-15 increased from just under 25% of disposable income to just over 28% – a rise of almost 4 percentage points. The increase, however, was slightly larger for those in the bottom quintile of the income distribution – from just over 29% of income to almost 34%.64 2.3.2. Anincreasing number of social dropouts The growing complexity of political decisions and the apparent increase in global private interests’ influence have led to a situation where politics seem to have become subordinate to economic interests. Consequently, ‘there is a growing perception that democratic elections seem to lose importance (no matter who will be elected policies will be approximately the same) pushing citizens into a more and 62 Maier, Karel, Workshop 1 Cities of tomorrow – Urban challenges, Brussels, June 2010. 63 ‘Le cout du logement’, Informations sociales No 155, CNAF, Paris, 2009. 64 The Social Situation in the European Union 2009, Eurostat, 2010, http://epp.eurostat.ec.europa.eu/cache/ITY_OFFPUB/KE-AG-10-001/EN/KE-AG-10-001-EN.PDF. more passive role’.65 Recent urban riots and mobilisation against local politicians’ decisions are signs that local residents are increasingly dissatisfied with this situation. There are also a growing number of people who do not feel as though they belong to the community in which they live. Cities will have to cope with a high number of social dropouts. One example of this trend is the sense of ‘no future’ shared by a large section of unemployed youths, and which may result in urban violence. Cities facing economic decline will have great difficulties facilitating socioeconomic insertion given the lack of jobs and reduced public budgets. A growing share of the unemployed is at risk of becoming marginalised, and there is a danger that the cities will see a ‘development of closed subcultures with fundamentally hostile attitudes to mainstream society, governed by different ideologies and social codes ranging from religious (or quasi-religious) to gangsterism (and overlaps between these)’.66 2.4. Diagnosis – depletion of natural resources 2.4.1. Urban sprawl and landconsumption Urban sprawl is a specific form of land take, resulting from the spread of low-density settlements, and is one of the main challenges that cities face.67 Urban sprawl concerns cities’ attractiveness, their resource efficiency, their transport infrastructure and the location of public and private services. What is more, it is very difficult to control, as the land being consumed by sprawl often lies outside the cities’ administrative areas. Weak planning regulation or its enforcement are commonplace in many European countries, leaving room for private interest to steer developments with a short-term profit logic in which common public goods are not valued. The European Environment Agency has expressed serious concerns about the development of urban sprawl in the EU, and land use has grown in importance as a European concern.68 Several factors may explain the ongoing development of urban sprawl. Many people are settling in peri-urban areas because they can find better quality housing with more living surface per capita. There is still a large difference in the average living area per person between cities in the EU-15 and cities in the EU-12: 15 m2 per person is average in Romanian cities, compared to 36 m2 per person in Italian cities and 40 m2 in German cities.69 Out-migration from the city centre to the peri-urban areas may also result from a demand for a greener, more attractive and family-friendly environment. The development of urban sprawl is closely linked to spatial segregation. For example, the increased gentrification of urban centres drives people to look for more affordable housing further from the city centre, while the middle and upper classes stay in the core city, and vice versa, with wealthy social classes leaving poor and run-down city centres. Urban sprawl is also related to the more extreme cases of spatial segregation in the form of a growing number of gated communities within and outside cities. Privatisation in Central and Eastern European Member States has led to private housing estate companies building massively in peri-urban areas with few constraints on architectural quality, land use or possible master plans. These different factors may explain why urban sprawl is in progress around both growing and shrinking cities.70 Urban sprawl is also caused by non-coordinated commercial zoning of land in peri-urban areas due to fragmented local government and planning systems, with each local municipality trying to maximise its local revenues.71 65 Tosics, Iván, issue paper, Cities of tomorrow, Brussels, January 2011. 66 Hall, Sir Peter, contribution to Cities of tomorrow, Brussels, April 2010. 67 Cf.

Cities of tomorrow -Challenges, visions, ways forward Urbansprawlhasmanynegativeconsequences.72 Urban sprawl makes it difficult to organise services: health care for the elderly, primary and secondary education for the youngest, etc. This leads to an increased risk of social isolation. As sprawl often takes place outside local administrative areas, the tax base financing public services may not coincide with the territorial distribution of the users. Urban sprawl results in increased energy consumption and congestion. There is an increased use of private cars in places where sprawl makes it too difficult and costly to implement good public transport due to low population density. Road infrastructure upgrades then become the only way to reduce travel time and improve accessibility, which in turn contributes to further urban sprawl in a vicious cycle. Urban sprawl leads to spatial segregation and social exclusion. The distance to basic services such as education, health and social services, and the lack of satisfactory public transport to homes and work and education places make people more and more car-dependant. Urban sprawl, therefore, excludes people who cannot afford to own or use a car, and who do not have the alternative of walking, cycling or taking public transport. Urban sprawl contributes to the loss of agricultural land and the increasing percentage of soil sealing, resulting in increasing risks of flood in urban areas. This consumption of agricultural land is foreseen to continue in all parts of Europe.73 Urban sprawl is behind the loss of biodiversity and the overexploitation of natural resources. Infrastructure development and urban sprawl results in a continued expansion of artificial surfaces across Europe at the expense of agro-ecosystems, grasslands and wetlands.74 Our current rate of natural-resource exploitation is steadily reducing biodiversity and degrading ecosystems, and, therefore, threatens urban and rural territories’ sustainability.75 Urban sprawl contributes to the economic decline of the traditional city centre. Functional mix has always been a characteristic of city centres. In fragmenting living and working spaces and in pushing companies or research centres outside city centres, urban sprawl may negatively impact on the economic dynamics of city centres. 2.4.2. Urban ecosystems under pressure In many ways, cities offer solutions for a more sustainable way of life, but despite improvements in air and water quality, as well as efforts to mitigate and adapt to climate change, European cities still face a number of environmental challenges. As engines of growth and generators of wealth, cities are also drivers of consumption and use of material resources. The density and compactness of cities reduce energy needs for heating and mobility, and offer possibilities for more efficient land use. But density in itself raises important questions about the environment’s capacity to accommodate the concentration of waste and pollution brought by density. Natural ecocycles, especially those for water, are being disrupted by a lack of natural soil and wetlands. The scarcity of land within cities creates pressure for an uncontrolled expansion outside the city cores driven by price rather than environmental considerations. Waste generation leads to land being used for landfills. The concentration of fine particles in the air has adverse effects on health. Noise pollution is amplified by concentrations of activities, in particular transport, and the use of hard, sound-reflecting materials, causing health problems.76 72 Thematic sub-group under the Territorial Cohesion and Urban Matters Workgroup, Final Report on Urban and Development Sprawl, July 2010. 73 A consortium of institutes working on strategies and development of sustainability assessment tools for urban–rural linkages, the PLUREL project (Peri-urban Land Use Relationships) www.plurel.net. 74 Between 2000 and 2006, agro-ecosystems, grasslands and wetlands respectively lost 0.9%, 1.2% and 2.7%.

Why is the depletion of natural resources a concern for Europe?77 In general, lost natural ecosystems and soil degradation damage a wide range of ecosystem services, including carbon and water cycling, and provision of food and fibre. Food and water security is a key concern here. The fragility of global food systems has become apparent over recent years. Driven by recurring food and economic crises throughout 2006 to 2009, the number of undernourished people in the world rose to more than one billion in 2009. The proportion of undernourished people in developing countries, which was previously declining, has also risen in the past few years (FAO, 2009). Ultimately these trends may lead to regional conflicts and social instability. Potential impacts on Europe include changes in the abundance of species, climate change, increased demand for and degradation of domestic resources (such as food and timber), and environment-induced immigration from developing countries. 77 European Environment Agency, The European Environment – State and Outlook 2010, http://www.eea.europa.eu/soer/europe-and-the-world/megatrends/decreasing-stocks-of-natural-resources. Cities of tomorrow -Challenges, visions, ways forward A global depletion of natural resources leads to a global competition for resources. The future competitiveness and vulnerability of European cities are dictated by the cities’ ability to shift to a less resource-intensive production and way of life, with less waste generation and increased recycling. Water is already periodically a scarce resource in many European cities, and water scarcity will increase with global warming. In addition, the reduction of wetlands, natural sinks and unsealed soil, in combination with the expansion of cities along ancient sea or riverbeds or their location along coastlines or river banks, dramatically increases the risk of flooding as climate change kicks in. 2.5. A diverse governance system The manner in which cities are governed varies greatly across the Member States: the numbers of administrative tiers or government levels range from two to four78 ; the average population size of the lowest tier (communes or municipalities) ranges from less than 2000 to over 150000. Although four-government-tier countries usually have a higher number of municipalities – e.g. well over 36000 in France, 12000 in Germany and 8000 in Italy and in Spain – the United Kingdom, also a four-government-tier country, has only 406 municipalities.79 In some countries, additional intermediary structures, such as groupings of first-tier government, have been set up to facilitate joint planning and action around strategic issues or joint infrastructure. The number of government tiers does not give any indication of the influence of the municipal level within the national government system. Powerful local administrations are those which exercise a high level of political autonomy and control over their budget by local taxation.80 High tax autonomy alone does not equal high political autonomy, which depends on whether large spending posts with little room for manoeuvre – such as education and health services – are financed locally or by a higher tier of government. In some countries, (major) cities are given a specific status that brings additional resources and responsibilities81 . Many Member States have undergone a decentralisation trend during the last thirty years, but decentralisation has in many cases been used as a means for higher government tiers to cut budgets, and increased local responsibilities have not been followed by the related resources. Decentralisation is associated with higher accountability, flexibility and efficiency, but too high a degree of decentralisation may not be suitable for more complex tasks and investments which need substantial financial resources or territorial coordination. There is also an additional risk of over-bureaucracy and corruption.82 The differences in regulatory and funding powers give cities very different possibilities for acting on the pressing issues on which their attractiveness and economic and social developments depend, even if they do not have formal responsibility for them. Cities’ own resources in terms of human resources for urban and strategic planning vary greatly across Europe. Housing is one of the most important questions for cities, but not all cities have competencies in this area. 78 Two-government-tier countries (one central, one sub-national): Bulgaria, Cyprus, Estonia, Finland, Lithuania, Luxembourg, Malta and Slovenia; three-government-tier countries: Austria, the Czech Republic, Denmark, Greece, Hungary, Ireland, Latvia, the Netherlands, Portugal, Romania, Slovakia and Sweden; four-government-tier countries: Belgium, France, Germany, Italy, Poland, Spain and the United Kingdom. 79 Figures provided by the Council of European Municipalities and Regions, on the basis of data from their member associations. 80 Second ‘State of European Cities Report’, op. cit. 81 Second ‘State of European Cities Report’, op. cit. 82 Second ‘State of European Cities Report’, op. cit.

Variation between countries in Central 2.6. Conclusions – a challenging future for the Cities of tomorrow The European model of urban development is based on economic, social and territorial cohesion and sustainability. A diagnosis of the state and outlook of European cities points to a number of threats to the European model of the city as presented in Chapter 1. The negative effects of globalisation, downward demographic trends and the economic crisis threaten economic, social and territorial cohesion. We are witnessing and Western Europe is much more pronounced, with local taxation rates ranging between 0% and more than 70%. Western European countries exhibit a relatively heterogeneous pattern, ranging from 5% to 55%. Among the Southern Member and Non-Member States, Greek and Turkish cities only derive a small share of their income from local taxation (under 10% in Greece and under 20% in Turkey), while in Italian, Spanish and Portuguese cities the local share is higher and there is greater variation between cities.

There is a marked risk that the increased diversity of the European urban population will lead to social fragmentation. Governance systems that have not evolved as quickly as governance needs, coupled with the growing role of private economic interests, may lead to increased urban sprawl, non-sustainable use of natural resources and energy, and increased spatial segregation. The territorial dimensions of urban development cannot be ignored. The success of cities in adapting to new economic circumstances is not only an internal matter for Cities of tomorrow -Challenges, visions, ways forward the cities themselves but also a concern for the rural areas surrounding them. When we take into account the diversity of cities’ situations in Europe, from global innovation hubs to abandoned manufacturing sites, it is clear that cities face very different realities and challenges. If we want to keep the European urban development model alive, it is vital that cities in crisis manage the transition to more sustainable development trajectories. We need policies for cities in crisis as well as policies for successful cities, otherwise we risk seeing a two-speed Europe with huge negative social, economic and environmental consequences. Although the outlook for many cities may appear gloomy, there are also opportunities to turn the major problems into more positive challenges. This demands that cities manage the transition to new development models that are green as well as inclusive and economically sustainable. Competitiveness in the global economy has to be reconciled with sustainable local economies, which demand an anchoring of key competences and resources in the local economic tissue. Social and spatial segregation have to be countered. Governance systems need to be adapted to evolving circumstances and include a territorial approach. Public services and city strategies need to adapt to diverse situations of shrinking budgets and populations, or growing migration, or economic growth which leaves an increasing number of people behind. 3. The Main Challenges for the Cities of tomorrow Cities of tomorrow -Challenges, visions, ways forward 3.1. Introduction – what can we say about future challenges? A challenge is a ‘task or situation that tests someone’s abilities’.83 ‘Challenge’ is often used as a euphemism for ‘problem’, but problems become challenges only if they are reformulated into a more or less daunting task. The same problem may give rise to different challenges – e.g. if a fire is the problem, the challenge might be either how to escape the fire or how to extinguish it. The same challenge may also address several problems, so for example if the challenge is ensuring sustainable urban mobility, the problems addressed may include obesity and health problems, segregation and exclusion, traffic congestion, etc. The future is what is still to come. In that sense it can be anything from now to eternity. For our purposes, the future is related to the nature and timescale of the challenges and the possible strategies for addressing them. The challenge of reducing greenhouse gas emissions has one time horizon, the mitigation of the negative effects of climate change another. The challenges faced by the Cities of tomorrow are those that we believe will be the most influential in a long-term perspective that goes beyond this decade. The future that interests us is the one that goes beyond the immediate and beyond the normal planning horizon, where many possible futures open out. Without the ability to both predict the future and understand the specific situations of every single European city, we cannot be precise about our cities’ most important future challenges. It would require the ability to foresee disruptive events and wild cards. For example, the recent upheaval in the Arab world came as a complete surprise to most Member States’ governments and illustrates the way unpredictable events, or chains of events, can have far-reaching consequences that dramatically change a given situation or alter a development trajectory. That said, many drivers behind the main challenges evolve in a stable and more or less predictable way. For instance, the ageing of the EU population may be projected with accuracy over a long period; globalisation will continue to exercise a strong influence on the location of firms and the evolution of the labour market; and the simulations and models of climate change and its effects are becoming increasingly precise. Therefore, it is possible, if not to predict, then to at least have a good understanding of the types of challenges our cities will face. This chapter focuses on what experts consider to be the major challenges that cities have to address to achieve a desirable future. Our ambition is to be neither exhaustive in terms of challenges for the Cities of tomorrow, nor speculative and focus on challenges that may materialise in the unknowable future; we simply want to raise awareness of the type of challenges cities are, and will be, facing, and that will have a strong influence on their future. Challenges cannot be addressed individually; their inter- relations and contradictions need to be properly understood. Challenges can rarely be isolated from each other and treated independently, as they are interrelated, often with seemingly contradictory objectives. For instance, the challenge of turning cities carbon-neutral must also be understood through a social inclusion perspective, where green technology needs to be accessible for all if we want to avoid energy poverty and exclusion. We would also like to draw attention to the way challenges are formulated and the type of governance frameworks that are put in place to address them. A challenge is never neutral. The way it is formulated reflects values and priorities. Challenges need to be formulated to align with our overall objective of sustainable territorial development in liveable cities all across Europe. Our overall objective, or our value base, is the European model of urban development presented in Chapter 1 (see section 1.5). This should be reflected in the way challenges are formulated. The challenges for the Cities of tomorrow are not problems to be solved but opportunities to be exploited. Chapter two 83 www.oxforddictionaries.com
