33 presented a diagnosis of the threats and weaknesses of European cities. In this chapter we point to the potential strengths and opportunities in European cities and we present scenarios for our Cities of tomorrow which are both desirable and possible. 3.2. The diverse, cohesive and attractive city 3.2.1. The potential of diversity Increasing immigration flows, an ageing population, a multiplication of real and virtual communities, and increasing economic, social and spatial segregation may lead to fragmentation of cities with isolated local communities, a loss of social cohesion and the formation of ghettos of all forms, both rich and poor. The challenge for the Cities of tomorrow lies in breaking the segregation and turning the diversity into a creative force for innovation, growth and well-being. Socio-economic, ethnic and cultural diversity may have positive effects on social cohesion, economic performance and social mobility. Much depends on the perspective on diversity, and whether we regard the city as a cluster of problems or as a place of freedom and creativity. The urban population – especially migrants – must not be looked on as a burden and source of deficit but as an opportunity. There is a positive correlation between the proportion of foreigners and urban economic wealth,84 which may be explained both by immigrants’ attraction to economically wealthy cities, and by the economic opportunities created by diversity. Although successful integration is very dependent on national policies and regulation, cities have a key role to play in countering the negative effects and stimulating the positive effects to fully exploit the potential creativity and innovation that may stem from diversity. There are strong links to be exploited between the diversity and social and territorial cohesion of a city and its economic competitiveness and attractiveness. Cooperation across ethnic, socio-professional and socio-cultural boundaries, as well as across territorial boundaries within cities, needs to be encouraged. Social initiatives are needed to improve social relations and improve access to the potential opportunities of a diverse city. Diversity is about culture, identity, history and heritage. People form the core of cities; cities need to be designed for all citizens and not just for the elite, for the tourists, or for the investors. People should be regarded as the key city asset and not as a demographic or social problem.85 84 Second ‘State of European Cities Report’, pp.15–16. 85 Boraine, Andrew, Presentation of Cities of tomorrow, March 2011. 34 Cities of tomorrow -Challenges, visions, ways forward A vision of the diverse city86 The main principle on which the diverse city is based, is not only the Socratic ‘Gnothi seauton’ (‘know thyself’) which was inscribed in the pronaos of the Temple of Apollo at Delphi, but also ‘know each other’. We need to work on strategies for mutual knowledge between all cultures present in the city: European and non-European cultures, middle-class and working-class culture (and poverty cultures, which are not necessarily ‘poor cultures’), ‘high’ and ‘low’ culture, and especially specific youth cultures. In the diverse city, there are no ghettos or gated communities, and there is no strict delimitation of territories according to different cultural or ethnic origins. Diverse cities look like Montreal at the end of the twentieth century with its many ‘ethnic villages’ – neighbourhoods with symbols of cultural identity (restaurants, grocery shops). In some other cities, there is a cultural and ethnic mix and dwellings reflecting different cultures87, while cultural diversity is reflected by public places and by shops that are, if not owned, then operated by people from all over the globe. In any of those shops, you may find a range of products that reflect different habits (cooking, dressing) and lifestyles. In a diverse city, public spaces become meeting places in the broadest sense: from just observing each other to physical meetings, interaction and communication and further, to forums where questions affecting the way the city spends its budget can be discussed openly as people have their say in public budgeting exercises. In a diverse city, solidarity is organised not only top- down – through imposing a middle-of-the-road cultural framework or through a generalised system of CCTV – but also, and even more, bottom-up, by facilitating and stimulating common projects for urban dwellers. This shift would also reduce the need for vertical social control, and old forms of horizontal social control could be restored. Information and communication technologies play an important role as people use them to express their creativity and to communicate about their culture; in some extreme cases, ‘to make sure that we’re talking with each other in a way that heals, not in a way that wounds’(speech by President Obama inTucson). In a diverse city, the different spatial and social perspectives that people have are respected. In the eyes of city dwellers, there is no such thing as one city: it resembles a kaleidoscope of views. The city is perceived differently by different people and they will use the ‘urban fabric’ accordingly. They will differ in their selection of places to avoid (because they are considered unsafe or ugly), places to prefer (cafés, shops, public spaces, museums), or trajectories to follow (to reach their destination and/or because of the presence of those preferred spots). 3.2.2. Turningdiversityintoadynamic asset Immigration and diversity are sources of wealth creation. Immigration and immigrants or ethnic minorities such as Roma people are often used to fuel political divisions. In times of crisis they are blamed for causing a drain on local tax resources, stealing jobs from the locals, undercutting wages, bringing criminality and insecurity to neighbourhoods, etc. Their key role in stimulating growth is easily forgotten.88 It is important to realise the potential value of each and every group and how they contribute to urban growth, i.e. to build wealth on different communities’ cultural assets and differences. 86 Builds on the presentation and inputs by Jan Vranken (Antwerp University). 87 For example, the Roma houses with their very unique architectural style, cf. presentation by Berescu, Catalin, Workshop 1 Cities of tomorrow – Urban challenges, Brussels, June 2010. 88 ‘In 2008, 36.4% of the [New York] city’s population and 42% of its work force were immigrants. According to a recent report by the state controller, New York City immigrants accounted for $ 215 billion in economic activity in 2008, 32% of the gross city product (GCP). Immigration’s contribution to the GCP increased by 61% from 2000 to 2008, indicating a high workforce participation rate and growth in wages. Immigrants are also starting a greater share of new businesses than native-born residents, revitalising commercial districts in every city neighbourhood.’ Article by E.R. Fuchs, Columbia University, in Crain’s New York Business, Feb. 8–14, 2010. Some cities are already turning growing diversity into a driver for growth and social progress. The Open Cities URBACT project87 aims to develop strategies to attract and integrate qualified migrants. However, cities hit by economic crisis may have difficulties in pursuing such strategies, especially if their population considers migration not as an asset but as a risk for local employment. The diverse city is an attractive city. Diversity is not just about ethnic or geographic origin; it is also about social diversity and different cultural expressions. 3.2.3. Ensuringacityfor all – thecohesivecity The cohesive city is not necessarily a city with complete equality and a homogenous population, but a city where everybody is welcome and their integrity is respected. The question of poorer or more affordable neighbourhoods must be seen in the context of diversity and inclusion. Overly homogenous neighbourhoods may not welcome alternative lifestyles and may be detrimental to creativity. Diversity needs be stimulated in a context of interaction and respect and some cities apply social mix strategies, for example tenure interventions in the housing sector. To evolve from tolerance to respect – from cohesion within the group to cohesion within the larger city and society – is one of the major challenges that the Cities of tomorrow face. ‘Perhaps the most important question for the future of European cities is the following: how are cohesion and A vision of the creative city Living art and culture are clearly visible in the creative city. There is a rich and diverse cultural supply offered by both established art institutions and grass-roots artistic groups and movements. Culture is the way inhabitants ‘live’ their city: their use of public spaces, street art, gastronomy, community events, festivals – these are all assets that contribute to a lively cultural life. It manifests itself in various forms, from creative use of public spaces to distinct urban furniture and street lighting. Cultural expression is encouraged. Within the creative city, culture is mainstreamed into the provision of public services. Distinct urban design and labelling systems help identify places. The dominance of messages from the private sector (advertisements) is counterbalanced and replaced by the increased visibility of public and community amenities and services. Such visibility may benefit from unified urban orientation systems. Urban legends and stories, which are all place-specific and help to ‘make’a place, are also visualised by statuettes, messages or signs on the asphalt. In the creative city, entrepreneurship by newcomers will be encouraged not only as an economic resource but also as a cultural challenge, represented in social events, and in a constant political and cultural effort to weave links not only within communities, but also with the rest of the world. 87 http://urbact.eu/en/projects/human-capital-entrepreneurship/open-cities/homepage/. 36 Cities of tomorrow -Challenges, visions, ways forward exclusion, polarisation and diversity related to tolerance and respect between the people and groups that are living in, working in, and visiting our cities? We define tolerance as the absence of conflicts between individuals and groups, and respect as a concept that relates to a more active attitude with a much more positive connotation than tolerance. Do, for example, more social contacts between individuals of different social groups also imply that these individuals will develop a different perspective on these groups (less stereotyped, more tolerance or perhaps even respect)?’90 The fight against deprivation must not jeopardise diversity and social mobility. Cities have to achieve a fine balance between eradicating poverty and deprivation and providing affordable housing and neighbourhoods that can accommodate alternative lifestyles. There is a need to avoid stigmatising deprived neighbourhoods and also to understand their functional role as transitional spaces for newcomers, for young people and for other less affluent groups that cannot afford to live in cities’ more wealthy areas. A big challenge for urban policy is to ensure this function The importance of social and public housing Public support schemes for housing are prominent in many cities. ‘Integrated strategies to address housing exclusion and homelessness have an important role to play in post-crisis policies, with a view to build cohesive and environmentally sustainable societies […] Concentrations of housing exclusion and homelessness can only be addressed through housing and urban regeneration programmes to promote sustainable communities and social mix.’91 In most Member States, municipalities are responsible for implementing social housing programmes to ensure access to adequate housing for all. In some countries, such as Sweden and Austria, the size of the municipal housing stock is significant (21% and 14% of the national housing stock respectively). In France, a law obliges municipalities with more than 3500 inhabitants to provide at least 20% social housing.92 of transitional space, without letting neighbourhoods turn into dead-end streets with no social mobility and no cohesion with the rest of the city. This question is important for the integration of newcomers, for the possibility of young people born in the city finding their own first dwellings and for the cultural and social diversity of the city. 3.2.4. Eradicating energy poverty and spatialexclusion Ninety per cent of social housing consists of buildings in need of refurbishment. These buildings often have low energy efficiency with many tenants living in fuel poverty. Better energy efficiency is key to alleviating the poverty of the most vulnerable, while increasing the quality of life for all citizens. Cities are faced with the challenge of upgrading existing housing stock and finding the most adequate solutions, while knowing that systems will evolve. Solutions, therefore, need to be flexible, cost-effective and sustainable. Energy efficiency may play a particular role in cities of 90 Vranken, Jan, issue paper, Brussels, 2010. 91 European Commission, Joint Report on Social Protection and Social Inclusion, 2010. http://ec.europa.eu/social/main.jsp?catId=757&langId=en. 92 CECODHAS, contribution to Cities of tomorrow, June 2010, and CECODHAS Housing Europe, Review of Housing Systems in the EU, 2011, forthcoming. EU-12 Member States where there are still a number of large housing estates with very high energy consumption. In some countries, flats have been privatised, resulting in a lack of effective collective management and very few or no resources for renovation. The modernisation of physical space is a necessary but insufficient condition for guaranteeing quality of life and neighbourhoods and cities with long-term sustainability. Other physical investments are as important for fighting exclusion as those directed towards energy efficiency. Accessibility to public transport and services and the availability and quality of public spaces and shopping areas, are other very important factors for inclusion and quality of life. To avoid lock-in effects and social immobility, it is crucial to ensure that everyone, especially the very young, has access to good quality education. The main social problems in our cities are less related to income level than to unequal resources and capabilities. Education keeps citizens engaged in society and public life and also acts as a counterforce to a sort of populism. Cities often make a great effort to attract and retain talented people from other parts of the world, but it could be more inclusive and costeffective to develop the talents that already exist in these cities. In addition, strategies to attract investments by supplying cheap labour can only give a short-term advantage ; in the longer-term, advantages need to build on qualifications, skills and innovation. 3.2.5. Developing social innovation Creativity and innovation are part of the standard toolbox of a city that is attractive and competitive. However, the concept of a ‘creative milieu’ is sometimes restricted to specific social groups: workers from the knowledge or leisure industries, artists, etc. But in the context of economic and financial crisis, social innovation offers an opportunity to widen the public space for creativity and innovation. ‘The scope for social innovation is particularly large at the moment when many existing institutions are showing signs of strain and when many social problems such as social cohesion, job creation, inner-city decay and youth unemployment seem resistant to orthodox solutions.’93 Social innovation can refer both to social processes of innovation and to innovation with a social goal. It is both a tool to empower and mobilise people’s creativity and an outcome of their action. Social innovation addresses social demands that are traditionally not taken care of by the market or existing institutions, and may be directed towards vulnerable groups in society. Social innovation is a wide concept that can take many different forms: grassroots projects such as new educational pathways for children or youth from disadvantaged groups; projects aimed at making life better for targeted groups; projects addressing societal changes; or systemic, enabling innovation, such as micro-credits.94 To foster inclusion, cities will have to develop social schemes to mobilise marginalised groups. For example, with schemes such as the ‘Community Self Build Agency’95 in the UK, cities may provide opportunities for long-term unemployed people to be empowered through collective work and activity-based networking. Such initiatives can be stepping stones for further educational pathways and for engagement in economic activities. Funding for social innovation projects may be difficult, as the social return on investment is difficult to account for in direct financial terms by comparison with pure business projects or hard investments. Projects are generally 93 Mulgan, Geoff, and Landry, Charles, The other invisible hand : Remaking charity for the 21st century, 1995, quoted by Jan Vranken, issue paper, Brussels, 2010. 94 Cf. Bureau of European Policy Advisers, Empowering people, driving change : Social innovation in the European Union, Brussels, May 2010. 95 Assisted by an architect, a group of people (around 15) builds a community house together. Most of these projects are directed towards long-term unemployed or other marginalised groups, such as drug addicts or alcoholics, with whom a type of social contract is set up. It links community needs (e.g. housing needs) with a reinsertion scheme (e.g. learning a trade). Through such projects, participants are empowered and may (re)-build confidence in their capacities and link up with the professional world. Cities of tomorrow -Challenges, visions, ways forward small-scale in budget terms, but people-intensive. To properly exploit social innovation, cities face the challenge of rescaling governance and articulating social innovation projects and strategies with their overall investment strategies. One way of doing this is to focus attention on public opinion about urban amenities and on adjusting priorities according to recommended changes – even if they’re not spectacular96 – or to use wider participatory processes, such as participatory budgeting, foresights involving citizens, etc. The provision of some public funding (or the attraction of private funding) can serve as a catalyst to mobilise other resources (volunteering and participation) which have many positive spillovers into social, political and economic activities in cities. 3.2.6. Adapting the city’seconomic and social lifetoan ageing population Most cities will face the challenge of adapting to the needs, demands and requirements of an ageing population. Even cities with a high share of young inhabitants will have elderly residents that live longer and are accustomed to high-quality social and cultural lives. A large share of the elderly population will need some form of daily care. Ageing will affect cities in different ways according to the purchasing power, vitality and engagement of the elderly population in society. As with ethnic and cultural diversity, an ageing but socially, culturally and economically active population should not be seen as a disadvantage. While the combination of the purchasing power and consumption of the 50–65-year-olds is one of the strongest drivers of the economy, the over 65s demand more public resources. But cities with a high quality of life, especially in terms of climate, leisure and cultural and social services, have the potential to attract affluent retired people, who will contribute to a viable residential economy. Less fortunate cities may face a combination of decreasing birth rates and an out-migration of the more active part of the population, resulting in a growing elderly population with limited economic resources. The challenge for cities with an increasingly large non-active population lies in their reduced tax-base, which must deal with an increased service demand. In the case of a shrinking population, local authorities will be confronted not only with a decline in their tax revenues, but also with the closure of shops and private services and increasingly vacant building stock. Neighbourhoods may risk turning into no man’s lands, speeding up the withdrawal of private interests in a vicious circle. In both cases, cities will have to meet a growing demand for social services, notably health. They will have to adapt public transport and improve accessibility to public places and housing. The very old will demand particular care, especially as the number of people affected by age-related neurological diseases has risen steeply. These demographic developments are not entirely negative for cities. The need for new and different forms of services and advanced health care will create business and job opportunities and scope for both social and more market-oriented innovation. Beyond the direct development of services for an ageing population, there is also a need to look at the mix of the whole population. The Cities of tomorrow will have to not only ensure that the elderly are well integrated in society, but also be attractive in terms of quality of life and opportunities for young people, not least young families. The creation of conditions for inter-generational integration and exchange is crucial. The elderly could play important roles in benevolent sectors, for instance in supporting the inclusion of marginalised groups by helping out with extra schooling needs, dealing with administrations, helping newcomers to discover the city’s cultural heritage, etc. The role of the elderly in integrating migrants and marginalised groups could to some extent balance reduced public resources and be an effective tool in community building. It would also increase tolerance for immigration and respect for immigrants, paving the way for increasing immigration to supplement our ageing population. 96 Querrien, Anne, Workshop 3 Cities of tomorrow – How to make it happen ?, Brussels, December 2010. 39 A vision of a multi-generational metropolis 97 ‘The new metropolis will be multi-generational. There will still be some clustering and differentiation of living by different age groups – students living in more affordable neighbourhoods but easily accessing the hot spots, the elderly organising collective life in more peripheral neighbourhoods, except for the most affluent. Multi-generational housing units will be found in city centres, in buildings with good technical and social services, where seniors do benevolent work teaching or looking after the young. Public cultural centres develop experiences of the local and of the whole world with the participation of the community. They are places for learning, imagining and experimenting with new technologies. These centres will be public spaces in their openness, like a theatre or a cinema or a café, but private/public partnership in ownership, like cultural institutions.’ 3.2.7. Attracting theyoung and making roomfor children A too narrow a focus on elderly people and their particular needs may have adverse effects on the attraction of younger people, discourage young people living in cities from having children or make families with children move to peri-urban areas. Even cities capable of attracting affluent retired people will have to attract younger people to ensure well-functioning services and more long-term sustainable prosperity. A common pattern in many European cities is that young, often single, people move to cities but then move out to peri-urban areas if they form a family and have children. A challenge for cities is to make it attractive for families with children to live in core cities. Good quality, easily accessible childcare and schools are obvious elements in a child-friendly city. Affordable and attractive housing suitable for family needs is also important, as are green areas and playgrounds and child-friendly streets. It must be easy for families to reconcile professional and private life, easy to bring children to childcare on the way to work, easy to buy and bring home food for a family, easy to take children to parks or cycle in the neighbourhood, etc. Such a child-oriented focus would be beneficial for elderly people and the overall attractiveness of cities. It could also be beneficial for overall fertility rates. 97 Anne Querrien, input to the third Cities of tomorrow workshop, December 2010. 40 Cities of tomorrow -Challenges, visions, ways forward VÄXJÖ – Sustainable energy policies - part of a model for managing complex urban change Växjö municipality in Southern Sweden has a dense and cohesive urban area (15 km2, 63000 people) as well as a large rural area (1900 km2, 20000 people), with population growth of 1-2% annually and an immigrant population of 18%. Those responsible for addressing local challenges are the municipality of Växjö, the County of Kronoberg, the University of Växjö, businesses (some 8 000, mostly SMEs) and NGOs. They have notably responded to the challenge of sustainable energy policy through a long-term environmental strategy. This includes strategic documents written together with residents and public, private and academic partners, incorporating interrelated policies, aims, measures and success indicators. The key document, from 2006, has been the extensive environmental programme. It contains an energy policy addressing local and global environmental challenges, and is structured into three sections: Living Life, Our Nature and Fossil-Free Fuel Växjö. So far, carbon dioxide emissions per inhabitant have fallen by 35% in 10 years, alongside economic growth of 69% (2008). Measures have also included cleaning up Lake Trummen, building a fossil-free fuel district heating and cooling system, constructing multi-storey houses of wood, making buildings more energy efficient and planning eco-friendly traffic. Växjö believes its strategy could be used in similar or smaller size towns. 3.3. The green and healthy city 3.3.1. Aholisticapproachtoenvironmental issues and energy efficiency Cities are not just economic engines, they are unrivalled as providers of the basic ingredients for quality of life in all its senses: environmental, cultural and social. Cities have to manage a range of environmental issues, such as quality of air and water, energy, waste and natural resources. In the future, cities may also have to secure food provision, especially in a context of shorter, more local, production– consumption chains. A city is a place where the many components of the natural ecosystem are interwoven with those of the social, economic, cultural and political urban system in a unique manner. A major challenge for all cities is to reconcile economic A vision of the compact and green city ‘An important basis for efficient and sustainable use of resources is a compact settlement structure. This can be achieved by spatial and urban planning, which prevents urban sprawl by strong control of land supply and of speculative development. The strategy of mixing housing, employment, education, supply and recreational use in urban neighbourhoods has proved to be especially sustainable.’ [The Leipzig Charter on Sustainable European Cities]98 The compact and green city offers an interesting urban landscape, a healthy functional mix, and a good quality of architecture and design in its built environment (public spaces, buildings and housing). It offers easy access to green areas and open space for everyone. It takes care of and makes use of its historical sites and monuments. Since people no longer need to search for green areas outside the city, they have moved back to the centres and no longer need to go to work or to leisure facilities by car. As an alternative, they can easily hop on clean and convenient public transport, which works efficiently due to the higher concentration of potential clients. These savings in transport free up more public space, and make cities cleaner and quieter. Furthermore, it has prevented the countryside from suffering from urban sprawl, preserving it for agriculture, forestry and nature. Cities of tomorrow -Challenges, visions, ways forward activities and growth with cultural, social and environmental considerations, as well as reconciling urban lifestyles with green constraints and opportunities. As focal points for consumption and innovation, cities can play a key role in shaping greener behaviour and consumption. Cities’ resilience also means a gradual retrofitting of the existing housing stock, taking into account environmental constraints such as mitigation of, and adaptation to, the impact of climate change. The affordability of housing costs in order to avoid migration flows towards suburban areas is also at stake. ‘Green and healthy’ go far beyond the reduction of CO2 emissions. Climate change is an important factor motivating cities to become more resource efficient. Like all economic actors, cities will have to take responsibility for reducing CO2 emissions. Cities are also in many ways best placed to act on the use and misuse of natural resources, and are set to play a key role in the implementation of the Europe 2020 strategy. The collective realisation of global climate targets will reduce the risks of severe flooding and droughts, uncontrolled migration of climate refugees and other adverse effects of extreme weather conditions. However, the simple reduction of CO2 emissions brings few direct benefits for cities. For cities, the amelioration of the air quality, the reduction of traffic congestion, and the health of their inhabitants are much more direct benefits of greener practices. Fine-particle air pollution is associated with more than 455 000 premature deaths every year in the EU’s 27 Member States.99 A recent study of air quality in 25 major EU cities indicates that if the WHO’s guidelines on this air pollution were carried out, life expectancy for those over 30 would increase by an average of 22 months, and over EUR 30 billion in health benefits could be realised each year.100 Asthma and other respiratory problems could also be reduced, not least among the young. Obesity is another major health problem in the Western world, as a range of obesity-related diseases cause premature deaths and rising health care costs. More nonmotorised mobility would not only reduce air pollution A vision of sustainable consumption modes101 The city of the future is run by the ‘energy subsidiary’ principle. In 2050, cities are highly energy efficient. The low energy demand (heating, cooling and electricity) will mainly be supplied by diverse local and regional renewable energy sources as well as co-generation. Smart grids will ensure decentralised solutions. New buildings do not consume fossil fuels; most of them produce electricity. They include facilities to park soft mobility vehicles like bikes. They come with a ‘user guide’, which is obligatory when letting any kind of building. Older buildings are refurbished and do not exceed a consumption of 50 kWh/m2/year. Fuel poverty has dramatically decreased. New consumption patterns have been adopted in 2050. Convenience stores have relocated throughout the cities and malls have vanished from city outskirts. Weekly fruit and vegetable markets have experienced a boost. Specialised stores can be found in city centres, and much of the market for household equipment is found online. Logistics have been improved: mail delivery is purely electronic, but goods delivery has expanded while car use diminishes. Agricultural land is used to produce not only food, but also materials and energy. Meat production has decreased while vegetarian and low meat diets have increased. 98 The Leipzig Charter on Sustainable European Cities is a key policy document in the field of urban development which has been proposed by the German Presidency and adopted by the Ministers in charge of urban planning [http://www.eu2007.de/en/News/download_docs/Mai/0524-N/075DokumentLeipzig Charta.pdf ]. 99 Study by the European Topic Centre on Air and Climate Change (ETC/ACC), European Environment Agency (EEA). 100 Aphekom research project funded jointly by the European Commission’s Community Action in the Field of Public Health. 101 Energy Cities, Workshop 2 Cities of tomorrow – Visions and models, Brussels, October 2010. but also reduce obesity and increase the general health and fitness of the population. Reduced congestion would also bring economic benefits by enabling a more efficient and productive use of time. Energy efficiency in buildings is directly related to social inclusion and the alleviation of energy poverty. Environmental quality is part of an integrated approach to attractiveness and well-being. Increased energy efficiency reduces the economic and energy vulnerability of cities. The related innovations, technologies and services are important drivers for a greener local economy. A pedestrian and cycle-friendly city with clean air and water, plenty of green spaces and high-quality built space is also an attractive city for people and for businesses. Urban green growth requires both technological and social innovation strategies, which have to be designed in relation to the overall development of the urban space. Environmental issues cannot be dissociated from demographic, economic, social, cultural and aesthetic issues. Green and clean mobility needs to take into account the requirements of the elderly or families with young children, as well as the conditions for shops and small businesses. The use of renewable energy technologies, such as solar panels or wind power must respect the architectural A vision of the green city102 While our cities have maintained high urban densities, a dream is coming true: greenery is invading the cities and boosting life and urban ecology. Entire urban areas have become extensive networks of blue and green areas and corridors; green creeps over millions of square metres of roof area and climbs walls, exploiting every possible niche. People love their ‘urban biotope’ and enjoy the variety of green and water areas, ranging from bigger parks and natural areas, to allotment gardens, pocket parks or potted plants on roof terraces. This environment offers a multitude of different uses and helps to keep people healthy – literally something for everybody. Parents play with their children on the many playgrounds, small and larger families meet for a barbeque in community gardens, the elderly watch the birds from a bench in a park close by and meet their friends, youngsters gather after school on grass plains or dip into the cool waters of the harbour to bathe, others exercise or go for a cycling tour along the green routes or take a boat trip along the stream. The pleasant and safe green areas have encouraged people to spend more time outside and boosted social life in the city. Most of these places are public ones, thus everybody benefits easily. Green life makes the city a pleasant and attractive place to live; people are proud of this and strongly identify with their city. But there is more to enjoy and to benefit from; letting nature invade our cities has provided cities with many additional free services. This has often reduced the need for expensive technological solutions and has allowed cities to function in smarter ways. Green walls and roofs are not only attractive but insulate the buildings against cold and heat, which helps energy saving and thus reduces the ecological footprint of cities. Outside, trees provide shadow and fresh air, important when the future is likely to bring more heat waves to many European regions. Urban greenery lets people breathe. Trees and shrubs filter particles out of the air; dense vegetation lessens noise and hides visual nuisance. Green is ubiquitous in the Cities of tomorrow and asphalt and concrete are held back to the minimum. Plant roots penetrate the soil, and the surface water of heavy rainfall can readily penetrate the ground, thus preventing urban floods. Ponds and urban wetlands store further rainwater and make a costly upgrade of the sewage system needless. Some green areas and walls recycle even our grey water while looking attractive and offering habitats for wildlife. 102 Georgi, Birgit, European Environment Agency, contribution to Cities of tomorrow, January 2011. Cities of tomorrow -Challenges, visions, ways forward and cultural heritage and the touristic potential of the city. Green neighbourhoods need to be affordable and allow a mix of functions and socio-economic groups so as to avoid spatial segregation. A necessary gradual retrofitting of the existing housing stock to reduce energy consumption and adapt it to new environmental conditions must not jeopardise the affordability of housing costs so as to avoid migration flows towards suburban areas. 3.3.2. Making mobilitysustainable, inclusiveand healthy The development of sustainable mobility is a key challenge for the Cities of tomorrow. Sustainable mobility includes several dimensions and components: sustainable, energy-efficient and affordable public transport systems; a friendly environment for soft transport modes such as cycling and walking; easy access to all neighbourhoods, by foot, by bike, by public transport; local transport networks that need to be well connected to regional networks; peri-urban networks that need to be planned within the context of overall land-use and spatial development; and transport nodes that need to be well integrated with social, cultural and economic activities, including leisure. Mobility infrastructure must be developed with a long-term perspective in which future needs and future urban, spatial and technological developments are considered. Sustainable mobility must be part of an integrated approach. The reduction of congestion is important from a health point of view, but it is not only about reducing CO2 emissions, pollution and noise – it is also about giving the citizens the possibility of re-conquering the city. Congestion is resource-inefficient; it consumes energy and creates unnecessary pollution, it is time consuming and it consumes space. It decreases the attractiveness and quality of the life103 of a place. Roads with heavy traffic are effectively barriers that cut through cities, isolating neighbourhoods and making them unattractive. Greener technology alone is not the solution: as vehicles slowly become more fuel-efficient and electric cars more affordable and adapted to consumer demands, there is a danger that car traffic will increase rather than decrease, so that at the local level, CO2 emissions, pollution and noise may be reduced, but congestion will be a growing problem. On a global scale, high levels of CO2 emissions will continue to be generated as long as electricity production is not entirely green. A vision of the transformation of out-dated traffic infrastructure to public spaces104 “What will mobility look like after peak oil in a post-oil society? There will be a tremendous reduction of the individual car traffic inherited from the past. The younger generation does not see the car as the most wanted form of mobility any longer, and, maybe more importantly, no longer sees the car as a symbol of social status. Spaces devoted to traffic in our car-dependent cities offer huge potential for re-densification or reclaiming traffic areas as public spaces. Will oversized and outdated traffic systems provide the structure for new green parks and public spaces, as happened in the nineteenth century when fortification walls were transformed into a catwalk for civic society? The Highline in New York, an old elevated train track, has been permanently transformed into a linear park and has been recognised as a role model for future public space. In the Ruhr area, the A40 motorway was closed for one weekend as part of Cultural Capital City RUHR 2010.” 103 Perception Surveys on Quality of Life in European cities, 2004, 2007 and 2010. 104 Rettich, Stefan, Workshop 3 Cities of tomorrow – How to make it happen ?, Brussels, December 2010. 45 Non-car mobility has to become more attractive. Cities are facing the challenge of changing the mobility habits and values of those living within the city as well as those commuting. This is not an easy task. Non-car mobility has to be made more attractive, while individual car traffic has to be made socially and economically less attractive. Making non-car mobility more attractive requires accessible public transport – accessible within the city and within its labour market basin, but also accessible to the elderly, the disabled and parents with small children. It requires easily accessible services, whether public or private, whether social, economic or cultural. It requires attractive public transport that can provide a positive experience of mobility, and transport nodes which become places for leisure, shopping, meetings, culture and other forms of social exchange. It requires pedestrian and bicycle-friendly roads and paths.105 Green or blue corridors may contribute to the renewal of urban space and increase the pleasure in going by foot, bike or boat, whether for leisure or commuting. To make non-car mobility more attractive, cities have to effectively combine and integrate different mobility modes and facilitate the switch between walking, cycling, using trams, buses, trains, etc. Multimodality must be favoured and public transport be made more attractive; it should also be easy to switch from car to public transport. The increasing reliance on private actors to develop and run specific sections or modes of transport makes multimodality a challenging task for cities, especially in a wider territorial context. Harmonised tariff systems with single fares independent of transport modes need to be developed, and timetables need to be integrated and planned for multimodal use. Public transport can be made more attractive. 105 In the 2007–13 programming period of cohesion policy, nearly EUR 700 million has been allocated to cycle lanes. Though this figure concerns not only urban cycle lanes but also rural ones, it is a good indicator of the importance devoted to cycling in some cities. Cycling lanes are part of both integrated transport and urban development plans. In a city like Helsinki, cyclists can enjoy 1 120 km of cycle paths, over 700 km of which are paved. Cities of tomorrow -Challenges, visions, ways forward BARCELONA – Linking territorial cohesion, sustainable urban transportation and the fight against spatial segregation The Barcelona City Council and local metropolitan administrations recognise sustainable mobility as a fundamental and social right of all citizens, believing it necessary for social interaction and human relations. Over the last two decades, transport has been part of their social cohesion policies. Barcelona’s 101 km2 are home to 1 638 000 residents (4992000 in its greater metropolitan region). With 16 217 inhabitants/km2, Barcelona is one of the most densely populated cities in Europe, thus mobility is a big challenge.106 Efforts have looked to ‘democratise’ streets and public spaces, integrate mobility projects for clean and sustainable urban transport, and share good practices for sustainable mobility. Barcelona illustrates what a European sustainable city can be like, with action taken to improve accessibility, affordability and efficiency of the public transport network, promote cycling, walking and other alternative forms of transport, and support the participation processes, the latter resulting in social demands and greater cooperation. Barcelona’s public bicycle service, Bicing, is an example of a successful and sustainable mobility programme which has been rapidly adopted by the targeted population. Its introduction shows a determined commitment to promote bicycle use as an affordable, efficient, sustainable and healthier mode of transport. 106 Some key figures illustrate the complexity of its transportation implications: the city has a road density of 6 000 cars per km2 (whereas, for example, Madrid has 2 300 cars per km2 and London 1 600 cars per km2). Barcelona is also the European city with most lanes of private traffic per km2. 3.3.3. Asustainablecitywithattractive open public spaces The quality and aesthetics of the built environment and of public spaces are important factors for a city’s attractiveness. Well functioning and attractive public spaces and a generally aesthetic environment can act as symbols of a city and of living together, and may create a sense of ownership of the city by its population. In Germany, the ‘Baukultur’ political initiative has brought about an involvement of all stakeholders and economic actors, civil society and planners, in a debate about a better, more solid and sustainable culture of building our environment. This means a shift in planning, from a traditional top-down planning culture to a more bottom-up process based on the involvement of stakeholders and residents.107 Ideally, public spaces should be multi-functional and multi-generational, be elderly-friendly and accommodate children, and be meeting places as well as serve specific functions, like libraries, playgrounds, education, etc.108 A mixture of functions within buildings or public spaces may also facilitate communication, business opportunities and innovation. For instance, some universities offer space for ex-students to locate their start-up companies at their premises after graduation. Such enterprise-friendly environments not only facilitate students’ transition to active life but also provide opportunities for cooperation between young entrepreneurs. A vision of a no-growth city109 “We used to say ‘God created the countryside, man created the city’. We have been very successful in designing cities and modelling, managing and controlling our environments. The trouble is that there have been unpredicted consequences. The current visionary point of view relies on tools which are not meeting our objectives. For example, when we think about the future, we are fascinated by maps which are provided by satellite and by geographic information systems. In many aspects this is completely useless from the point of view of creating a good city, a good society. Some of the tools we have for constructing cities will potentially have bad consequences. The idea of managing the city to the extreme may make us completely unhappy. Europe has an extraordinary advantage in many ways in the fact that our cities are not growing any more. The greatest challenge is to achieve simplicity – de-engineer, de-commercialise, de-hierarchise, de-grow – while maintaining spirit, emotion and hope in the future.
