Meaning

A city can be distinguished from other human settlements by its relatively great size, but also by its functions and its special symbolic status, which may be conferred by a central authority. The term can also refer either to the physical streets and buildings of the city or to the collection of people who dwell there, and can be used in a general sense to mean
urban Urban means "related to a city". In that sense, the term may refer to: * Urban area, geographical area distinct from rural areas * Urban culture, the culture of towns and cities Urban may also refer to: General * Urban (name), a list of people ...
rather than rural territory.Kevin A. Lynch, "What Is the Form of a City, and How is It Made?"; in Marzluff et al. (2008), p. 678. "The city may be looked on as a story, a pattern of relations between human groups, a production and distribution space, a field of physical force, a set of linked decisions, or an arena of conflict. Values are embedded in these metaphors: historic continuity, stable equilibrium, productive efficiency, capable decision and management, maximum interaction, or the progress of political struggle. Certain actors become the decisive elements of transformation in each view: political leaders, families and ethnic groups, major investors, the technicians of transport, the decision elite, the revolutionary classes."

s which play a vital role in long-distance trade, are cities disconnected from the countryside which feeds them.Marshall (1989), p. 15. "The mutual interdependence of town and country has one consequence so obvious that it is easily overlooked: at the global scale, cities are generally confined to areas capable of supporting a permanent agricultural population. Moreover, within any area possessing a broadly uniform level of agricultural productivity, there is a rough but definite association between the density of the rural population and the average spacing of cities above any chosen minimum size." Thus, centrality within a productive region influences siting, as economic forces would in theory favor the creation of market places in optimal mutually reachable locations.

"From the simplest forms of exchange, when peasant farmers literally brought their produce from the fields into the densest point of interaction—giving us market towns—the significance of central places to surrounding territories began to be asserted. As cities grew in complexity, the major civic institutions, from seats of government to religious buildings, would also come to dominate these points of convergence.

generally follows one or more basic patterns: geomorphic, radial, concentric, rectilinear, and curvilinear. Physical environment generally constrains the form in which a city is built. If located on a mountainside, urban structure may rely on terraces and winding roads. It may be adapted to its means of subsistence (e.g. agriculture or fishing). And it may be set up for optimal defense given the surrounding landscape. Beyond these "geomorphic" features, cities can develop internal patterns, due to natural growth or to

, "What Sort of a Legal Space is a City?" in Brighenti (2013), pp. 1–20. "Municipalities, within this frame, are understood as nested within the jurisdictional space of the provinces. Indeed, rather than freestanding legal sites, they are imagined as products (or 'creatures') of the provinces who may bring them into being or dissolve them as they choose. As with the provinces their powers are of a delegated form: they may only exercise jurisdiction over areas that have been expressly identified by enabling legislation. Municipal law may not conflict with provincial law, and may only be exercised within its defined territory.
Yet we are ndanger fmissing the reach of municipal law: ' en in highly constitutionalized regimes, it has remained possible for municipalities to micro-manage space, time, and activities through police regulations that infringe both on constitutional rights and private property in often extreme ways' (Vaverde 2009: 150). While liberalism fears the encroachments of the state, it seems less worried about those of the municipality. Thus if a national government proposed a statute forbidding public gatherings or sporting events, a revolution would occur. Yet municipalities routinely enact sweeping by-laws directed at open ended (and ill-defined) offences such as loitering and obstruction, requiring permits for protests or requiring residents and homeowners to remove snow from the city's sidewalks."

Greenbeg, Clifford Kaufman, & Joseph Drew, "Service Delivery Rules and the Distribution of Local Government Services: Three Detroit Bureaucracies"; in Hahn & Levine (1980). "Local government bureaucracies more or less explicitly accept the goal of implementing rational criteria for the delivery of services to citizens, even though compromises may have to be made in the establishment of these criteria. These production oriented criteria often give rise to "service deliver rules", regularized procedures for the delivery of services, which are attempts to codify the productivity goals of urban service bureaucracies. These rules have distinct, definable distributional consequences which often go unrecognized. That is, the decisions of governments to adopt rational service delivery rules can (and usually do) differentially benefit citizens."Robert L. Lineberry, "Mandating Urban Equality: The Distribution of Municipal Public Services"; in Hahn & Levine (1980). See: Hawkins v. Town of Shaw (1971). Responsibility for administration usually falls on the city government, though some services may be operated by a higher level of government, while others may be privately run.

Because developers require cash up-front, cities transform promises of future tax revenues into securities that far-flung buyers and sellers exchange through local markets."

.Gupta, Verrest, and Jaffe, "Theorizing Governance", in Gupta et al. (2015), pp. 31–33. "The concept of good governance itself was developed in the 1980s, primarily to guide donors in development aid (Doonbos 2001:93). It has been used both as a condition for aid and a development goal in its own right. Key terms in definitions of good governance include participation, accountability, transparency, equity, efficiency, effectiveness, responsiveness, and rule of law (e.g. Ginther and de Waart 1995; UNDP 1997; Woods 1999; Weiss 2000). At the urban level, this normative model has been articulated through the idea of good urban governance, promoted by agencies such as UN Habitat. The Colombian city of Bogotá has sometimes been presented as a model city, given its rapid improvements in fiscal responsibility, provision of public services and infrastructure, public behavior, honesty of the administration, and civic pride." The concepts of governance and good governance are especially invoked in the emergent megacities, where international organizations consider existing governments inadequate for their large populations.

is used by government to divest citizens of their property in cases where its use is required for a project.McQuillin (1937/1987), §§1.75–179. "Zoning, a relatively recent development in the administration of local governmental units, concerns itself with the control of the use of land and structures, the size of buildings, and the use-intensity of building sites. Zoning being an exercise of the police power, it must be justified by such considerations as the protection of public health and safety, the preservation of taxable property values, and the enhancement of community welfare. Municipal powers to implement and effectuate city plans are usually ample. Among these is the power of eminent domain, which has been used effectively in connection with slum clearance and the rehabilitation of blighted areas. Also available to cities in their implementation of planning objectives are municipal powers of zoning, subdivision control and the regulation of building, housing and sanitation principles." Planning often involves tradeoffs—decisions in which some stand to gain and some to lose—and thus is closely connected to the prevailing political situation. The

dates to some of the earliest known cities, especially in the Indus Valley and Mesoamerican civilizations, which built their cities on grids and apparently zoned different areas for different purposes. The effects of planning, ubiquitous in today's world, can be seen most clearly in the layout of planned communities, fully designed prior to construction, often with consideration for interlocking physical, economic, and cultural systems.

.Mike Davis, "The Urbanization of Empire: Megacities and the Laws of Chaos"; ''Social Text'' 22(4), Winter 2004. "Although studies of the so-called urban informal economy have shown myriad secret liaisons with outsourced multinational production systems, the larger fact is that hundreds of millions of new urbanites must further subdivide the peripheral economic niches of personal service, casual labor, street vending, rag picking, begging, and crime.
This outcast proletariat—perhaps 1.5 billion people today, 2.5 billion by 2030—is the fastest-growing and most novel social class on the planet. By and large, the urban informal working class is not a labor reserve army in the nineteenth-century sense: a backlog of strikebreakers during booms; to be expelled during busts; then reabsorbed again in the next expansion. On the contrary, this is a mass of humanity structurally and biologically redundant to the global accumulation and the corporate matrix.
It is ontologically both similar and dissimilar to the historical agency described in the ''Communist Manifesto''. Like the traditional working classes, it has radical chains in the sense of having little vested interest in the reproduction of private property. But it is not a socialized collectivity of labor and it lacks significant power to disrupt or seize the means of production. It does possess, however, yet unmeasured powers of subverting urban order."

"Why do anonymous people—the poor, the underprivileged, the unconnected—frequently prefer life under miserable conditions in tenements to the healthy order and tranquility of small towns or the sanitary subdivisions of semirural developments? The imperial planners and architects knew the answer, which is as valid today as it was 2,000 years ago. Big cities were created as power images of a competitive society, conscious of its achievement potential. Those who came to live in them did so in order to participate and compete on any attainable level. Their aim was to share in public life, and they were willing to pay for this share with personal discomfort. 'Bread and games' was a cry for opportunity and entertainment still ranking foremost among urban objectives. Sports also play a major role in city branding and local

Gold, eds., ''Olympic Cities: City Agendas, Planning and the World's Games'', 1896–2016; London & New York: Routledge (Taylor & Francis), 2008/2011; . "All this media exposure, provided it is reasonably positive, influences many tourist decisions at the time of the Games. This tourism impact will focus on, but extend beyond, the city to the country and the wider global region. More importantly, there is also huge long term potential for both tourism and investment (Kasimati, 2003).
No other city marketing opportunity achieves this global exposure. At the same time, provided it is carefully managed at the local level, it also gives a tremendous opportunity to heighten and mobilize the commitment of citizens to their own city. The competitive nature of sport and its unrivalled capacity to be enjoyed as a mass cultural activity gives it many advantages from the marketing point of view (S.V. Ward, 1998, pp. 231–232). In a more subtle way it also becomes a metaphor for the notion of cities having to compete in a global marketplace, a way of reconciling citizens and local institutions to the wider economic realities of the world."

s, and military principles continue to influence urban design. Indeed, war may have served as the social rationale and economic basis for the very earliest cities.Mumford (1961), pp. 39–46. "As the physical means increased, this one-sided power mythology, sterile, indeed hostile to life, pushed its way into every corner of the urban scene and found, in the ''new'' institution of organized war, its completest expression. Thus both the physical form and the institutional life of the city, from the very beginning to the urban implosion, were shaped in no small measure by the irrational and magical purposes of war. From this source sprang the elaborate system of fortifications, with walls, ramparts, towers, canals, ditches, that continued to characterize the chief historic cities, apart from certain special cases—as during the Pax Romana—down to the eighteenth century. War brought concentration of social leadership and political power in the hands of a weapons-bearing minority, abetted by a priesthood exercising sacred powers and possessing secret but valuable scientific and magical knowledge."

Infrastructure

Urban
infrastructure Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and priv ...
involves various physical networks and spaces necessary for transportation, water use, energy, recreation, and public functions.Joel A. Tarr, "The Evolution of the Urban Infrastructure in the Nineteenth and Twentieth Centuries"; in Hanson (1984). Infrastructure carries a high initial cost in fixed capital (pipes, wires, plants, vehicles, etc.) but lower marginal costs and thus positive economies of scale.Wellman & Spiller, "Introduction", in Wellman & Spiller (2012). Because of the higher barriers to entry, these networks have been classified as natural monopoly, natural monopolies, meaning that economic logic favors control of each network by a single organization, public or private. Infrastructure in general (if not every infrastructure project) plays a vital role in a city's capacity for economic activity and expansion, underpinning the very survival of the city's inhabitants, as well as technological, commercial, industrial, and social activities. Structurally, many infrastructure systems take the form of network theory, networks with redundant links and multiple pathways, so that the system as a whole continue to operate even if parts of it fail.Kath Wellman & Frederik Pretorius, "Urban Infrastructure: Productivity, Project Evaluation, and Finance"; in Wellman & Spiller (2012). The particulars of a city's infrastructure systems have historical path dependence because new development must build from what exists already. Megaprojects such as the construction of airports, power plants, and railways require large upfront investments and thus tend to require funding from national government or the private sector. Privatization may also extend to all levels of infrastructure construction and maintenance. Urban infrastructure ideally serves all residents equally but in practice may prove uneven—with, in some cities, clear first-class and second-class alternatives.


Utilities

Public utility, Public utilities (literally, useful things with general availability) include basic and essential infrastructure networks, chiefly concerned with the supply of water, electricity, and telecommunications capability to the populace. Sanitation, necessary for good health in crowded conditions, requires water supply and waste management as well as individual hygiene. Urban water systems include principally a water supply network and a network (Sewerage, sewerage system) for
sewage Sewage (or domestic sewage, domestic wastewater, municipal wastewater) is a type of wastewater that is produced by a community of people. It is typically transported through a sewer system. Sewage consists of wastewater discharged from residenc ...
and stormwater. History of water supply and sanitation, Historically, either local governments or private companies have administered urban water supply, with a tendency toward government water supply in the 20th century and a tendency toward private operation at the turn of the twenty-first. The market for private water services is dominated by two French companies, Veolia Water (formerly Vivendi) and Engie (formerly Suez (company, 1997–2008), Suez), said to hold 70% of all water contracts worldwide.Karen Bakker, "Archipelagos and networks: urbanization and water privatization in the South"; ''The Geographical Journal'' 169(4), December 2003; . "The diversity of water supply management systems worldwide—which operate along a continuum between fully public and fully private—bear witness to repeated shifts back and forth between private and public ownership and management of water systems." Modern urban life relies heavily on the energy transmitted through electricity for the operation of electric machines (from household Home appliance, appliances to outline of industrial machinery, industrial machines to now-ubiquitous electronics, electronic systems used in communications, business, and government) and for traffic lights, street lights, and indoor lighting. Cities rely to a lesser extent on hydrocarbon fuels such as gasoline and natural gas for transportation, heating, and cooking. Telecommunications infrastructure such as telephone lines and coaxial cables also traverse cities, forming dense networks for mass communication, mass and point-to-point (telecommunications), point-to-point communications.


Transportation

Because cities rely on specialization and an economic system based on wage labour, their inhabitants must have the ability to regularly travel between home, work, commerce, and entertainment. Citydwellers travel foot or by wheel on roads and walkways, or use special rapid transit systems based on tunnel, underground, light rail, overground, and Elevated railway, elevated rail. Cities also rely on long-distance transportation (truck, rail transport, rail, and airplane) for economic connections with other cities and rural areas.Tom Hart, "Transport and the City"; in Paddison (2001). Historically, city streets were the domain of horses and their riders and pedestrians, who only sometimes had sidewalks and transit mall, special walking areas reserved for them. In the West, bicycles or (velocipedes), efficient human-powered machines for short- and medium-distance travel, enjoyed a period of popularity at the beginning of the twentieth century before the rise of automobiles. Soon after, they gained a more lasting foothold in Asian and African cities under European influence. In Western cities, industrializing, expanding, and electrification, electrifying public transit systems and especially streetcars enabled urban expansion as new residential neighborhoods sprung up along transit lines and workers rode to and from work downtown.J. Allen Whitt & Glenn Yago, "Corporate Strategies and the Decline of Transit in U.S. Cities"; ''Urban Affairs Quarterly'' 21(1), September 1985. Since the mid-twentieth century, cities have relied heavily on motor vehicle transportation, with major effects of the car on societies, implications for their layout, environment, and aesthetics.Iain Borden, "Automobile Interstices: Driving and the In-Between Spaces of the City"; in Brighenti (2013). (This transformation occurred most dramatically in the US—where corporate and governmental policies favored automobile transport systems—and to a lesser extent in Europe.) The rise of personal cars accompanied the expansion of urban economic areas into much larger

es, subsequently creating ubiquitous traffic issues with accompanying construction of new highways, wider streets, and alternative walkways for pedestrians. However, severe traffic jams still occur regularly in cities around the world, as private car ownership and urbanization continue to increase, overwhelming existing urban street networks. The urban Public transport bus service, bus system, the world's most common form of public transport, uses a network of scheduled bus route, routes to move people through the city, alongside cars, on the roads. Economic function itself also became more decentralized as concentration became impractical and employers relocated to more car-friendly locations (including edge cities). Some cities have introduced bus rapid transit systems which include exclusive bus lanes and other methods for prioritizing bus traffic over private cars. Many big American cities still operate conventional public transit by rail, as exemplified by the ever-popular New York City Subway system. Rapid transit is widely used in Europe and has increased in Latin America and Asia. Walking and cycling ("non-motorized transport") enjoy increasing favor (more pedestrian zones and bike lanes) in American and Asian urban transportation planning, under the influence of such trends as the healthy city, Healthy Cities movement, the drive for

, and the idea of a carfree city. Techniques such as road space rationing and road pricing, road use charges have been introduced to limit urban car traffic.


Housing

Housing of residents presents one of the major challenges every city must face. Adequate housing entails not only physical Shelter (building), shelters but also the physical systems necessary to sustain life and economic activity. Owner-occupancy, Home ownership represents status and a modicum of economic security, compared to renting which may consume much of the income of low-wage urban workers. Homelessness, or lack of housing, is a challenge currently faced by millions of people in countries rich and poor.


Ecology

Urban ecosystems, influenced as they are by the density of human buildings and activities, differ considerably from those of their rural surroundings. Anthropogenic

s and waste, as well as Agriculture, cultivation in gardens, create physical and chemical environments which have no equivalents in wilderness, in some cases enabling exceptional biodiversity. They provide homes not only for immigrant humans but also for introduced species, immigrant plants, bringing about interactions between species which never previously encountered each other. They introduce frequent disturbance (ecology), disturbances (construction, walking) to plant and animal habitats, creating opportunities for Secondary succession, recolonization and thus favoring ecological succession, young ecosystems with r/K selection theory, r-selected species dominant. On the whole, urban ecosystems are less complex and productive than others, due to the diminished absolute amount of biological interactions.S.T.A. Pickett, M.L. Cadenasso, J.M. Grove, C.H. Nilon, R.V. Pouyat, W.C. Zipperer, & R. Costanza, "Urban Ecological Systems: Linking Terrestrial Ecological, Physical, and Socioeconomic Components of Metropolitan Areas"; in Marzluff et al. (2008). Typical urban fauna include insects (especially ants), rodents (mouse, mice, rats), and birds, as well as cats and dogs (domestication, domesticated and feral). Large predators are scarce. Cities generate considerable

s, locally and at longer distances, due to concentrated populations and technological activities. From one perspective, cities are not ecologically sustainable due to their resource needs. From another, proper management may be able to ameliorate a city's ill effects. Air pollution arises from various forms of combustion, including fireplaces, wood or coal-burning stoves, other heating systems, and internal combustion engines. Industrialized cities, and today third-world megacities, are notorious for veils of smog (industrial haze) which envelop them, posing a chronic threat to the health of their millions of inhabitants.Peter Adey, "Coming up for Air: Comfort, Conflict and the Air of the Megacity"; in Brighenti (2013), p. 103. Urban soil contains higher concentrations of heavy metals (especially lead, copper, and nickel) and has lower pH than soil in comparable wilderness. Modern cities are known for creating their own microclimates, due to concrete, asphalt, and other artificial surfaces, which heat up in sunlight and channel rainwater into Storm drain, underground ducts. The Geography of New York City#Climate, temperature in New York City exceeds Climate of New York (state), nearby rural temperatures by an average of 2–3 °C and at times 5–10 °C differences have been recorded. This effect varies nonlinearly with population changes (independently of the city's physical size). Aerial particulates increase rainfall by 5–10%. Thus, urban areas experience unique climates, with earlier flowering and later leaf dropping than in nearby countries. Poor and working-class people face disproportionate exposure to environmental risks (known as environmental racism when intersecting also with racial segregation). For example, within the urban microclimate, less-vegetated poor neighborhoods bear more of the heat (but have fewer means of coping with it). One of the main methods of improving the urban ecology is including in the cities more urban green space: parks, gardens, lawns, and trees. These areas improve the health, the well-being of the human, animal, and plant populations of the cities. Well-maintained urban trees can provide many social, ecological, and physical benefits to the residents of the city. A study published in Nature's Scientific Reports journal in 2019 found that people who spent at least two hours per week in nature were 23 percent more likely to be satisfied with their life and were 59 percent more likely to be in good health than those who had zero exposure. The study used data from almost 20,000 people in the UK. Benefits increased for up to 300 minutes of exposure. The benefits applied to men and women of all ages, as well as across different ethnicities, socioeconomic status, and even those with long-term illnesses and disabilities. People who did not get at least two hours – even if they surpassed an hour per week – did not get the benefits. The study is the latest addition to a compelling body of evidence for the health benefits of nature. Many doctors already give nature prescriptions to their patients. The study didn't count time spent in a person's own yard or garden as time in nature, but the majority of nature visits in the study took place within two miles from home. "Even visiting local urban green spaces seems to be a good thing," Dr. White said in a press release. "Two hours a week is hopefully a realistic target for many people, especially given that it can be spread over an entire week to get the benefit."


World city system

As the world becomes more closely linked through economics, politics, technology, and culture (a process called
globalization Globalization, or globalisation (Commonwealth English; see spelling differences), is the process of interaction and integration among people, companies, and governments worldwide. The term ''globalization'' first appeared in the early 20t ...
), cities have come to play a leading role in transnational affairs, exceeding the limitations of international relations conducted by national governments.Gupta et al. (2015), 5–11. "Current globalization, characterized by hyper capitalism and technological revolutions, is understood as the growing intensity of economic, demographic, social, political, cultural and environmental interactions worldwide, leading to increasing interdependence and homogenization of ideologies, production and consumption patterns and lifestyles (Pieterse 1994; Sassen 1998). Decentralization processes have increased city-level capacities of city authorities to develop and implement local social and developmental policies. Cities as homes of the rich, and of powerful businesses, banks, stock markets, UN agencies and NGOs, are the location from which global to local decision-making occurs (e.g. New York, London, Paris, Amsterdam, Hong Kong, São Paulo)." This phenomenon, resurgent today, can be traced back to the Silk Road,

around the world, effectively eliminating the distance between cities for the purposes of the international markets and other high-level elements of the world economy, as well as personal communications and mass media.


Global city

A global city, also known as a world city, is a prominent centre of trade, banking, finance, innovation, and markets. Saskia Sassen used the term "global city" in her 1991 work, ''The Global City: New York, London, Tokyo'' to refer to a city's Power (social and political), power, status, and cosmopolitanism, rather than to its size. Following this view of cities, it is possible to Global city#GaWC study, rank the world's cities hierarchically.John Friedmann and Goetz Wolff, "World City Formation: An Agenda for Research and Action," ''International Journal of Urban and Regional Research'', 6, no. 3 (1982): 319 Global cities form the capstone of the global hierarchy, exerting command and control through their economic and political influence. Global cities may have reached their status due to early transition to post-industrial society, post-industrialism or through inertia which has enabled them to maintain their dominance from the industrial era. This type of ranking exemplifies an emerging discourse in which cities, considered variations on the same ideal type, ''must'' compete with each other globally to achieve prosperity. Critics of the notion point to the different realms of power and interchange. The term "global city" is heavily influenced by economic factors and, thus, may not account for places that are otherwise significant. Paul James (academic), Paul James, for example argues that the term is "reductive and skewed" in its focus on financial systems. Multinational corporations and banks make their headquarters in global cities and conduct much of their business within this context. American firms dominate the international markets for law firm, law and engineering and maintain branches in the biggest foreign global cities. Global cities feature concentrations of extremely wealthy and extremely poor people. Their economies are lubricated by their capacity (limited by the national government's immigration policy, which functionally defines the supply side of the labor market) to recruit low- and high-skilled immigrant workers from poorer areas. More and more cities today draw on this globally available labor force.


Transnational activity

Cities increasingly participate in world political activities independently of their enclosing nation-states. Early examples of this phenomenon are the sister city relationship and the promotion of multi-level governance within the European Union as a technique for European integration.Herrschel & Newman (2017), pp. 3–4. "Instead, the picture is becoming more detailed and differentiated, with a growing number of sub-national entities, cities, city-regions and regions, becoming more visible in their own right, either individually, or collectively as networks, by, more or less tentatively, stepping out of the territorial canvas and hierarchical institutional hegemony of the state. Prominent and well-known cities, and those regions with a strong sense of identity and often a quest for more autonomy, have been the most enthusiastic, as they began to be represented beyond state borders by high-profile city mayors and some regional leaders with political courage and agency. This, then, became part of the much bigger political project of the European Union (EU), which has offered a particularly supportive environment for international engagement by—and among—subnational governments as part of its inherent integrationist agenda." Cities including Hamburg, Prague,
Amsterdam Amsterdam ( , , , lit. ''The Dam on the River Amstel'') is the capital and most populous city of the Netherlands, with The Hague being the seat of government. It has a population of 907,976 within the city proper, 1,558,755 in the urban ar ...
, The Hague, and City of London maintain their own embassies to Brussels and the European Union, the European Union at Brussels. New urban dwellers are increasingly transmigrants, keeping one foot each (through telecommunications if not travel) in their old and their new homes.


Global governance

Cities participate in global governance by various means including membership in global networks which transmit norms and regulations. At the general, global level, United Cities and Local Governments (UCLG) is a significant umbrella organization for cities; regionally and nationally, Eurocities, Asian Network of Major Cities 21, the Federation of Canadian Municipalities the National League of Cities, and the United States Conference of Mayors play similar roles.Sofie Bouteligier,
Inequality in new global governance arrangements: the North–South divide in transnational municipal networks
"; ''Innovation: The European Journal of Social Science Research'' 26(3), 2013; . "City networks are not a new phenomenon, but it was the 1990s that saw an explosion of such initiatives, especially in the environmental domain. This is mostly ascribed to (chapter 28 of) Agenda 21, which recognizes the role of local authorities in the promotion of sustainable development and stimulates exchange and cooperation between them."
Herrschel & Newman (2017), p. 82. UCLG took responsibility for creating Agenda 21 for culture, a program for cultural policy, cultural policies promoting sustainable development, and has organized various conferences and reports for its furtherance.Nancy Duxbury & Sharon Jeannotte,
Global Cultural Governance Policy
"; Chapter 21 in ''The Ashgate Research Companion to Planning and Culture''; London: Ashgate, 2013.
Networks have become especially prevalent in the arena of environmentalism and specifically climate change following the adoption of Agenda 21. Environmental city networks include the C40 Cities Climate Leadership Group, World Association of Major Metropolises ("Metropolis"), the United Nations Global Compact#UN Global Compact – Cities Programme, United Nations Global Compact Cities Programme, the Carbon Neutral Cities Alliance (CNCA), the Covenant of Mayors and the Compact of Mayors, ICLEI, ICLEI – Local Governments for Sustainability, and the Transition town, Transition Towns network. Cities with world political status as meeting places for advocacy groups, non-governmental organizations, lobbyists, educational institutions, intelligence agencies, military contractors, information technology firms, and other groups with a stake in world policymaking. They are consequently also sites for symbolic protest.


United Nations System

The United Nations System has been involved in a series of events and declarations dealing with the development of cities during this period of rapid urbanization. * The Habitat I conference in 1976 adopted the "Vancouver Declaration on Human Settlements" which identifies urban management as a fundamental aspect of economic development, development and establishes various principles for maintaining urban habitats. * Citing the Vancouver Declaration, the UN General Assembly in December 1977 authorized the United Nations Commission Human Settlements and the HABITAT Centre for Human Settlements, intended to coordinate UN activities related to housing and settlements.Peter R. Walker, "Human Settlements and Urban Life: A United Nations Perspective"; ''Journal of Social Distress and the Homeless'' 14, 2005; . * The 1992 Earth Summit in Rio de Janeiro resulted in a set of international agreements including Agenda 21 which establishes principles and plans for

. * The Habitat II conference in 1996 called for cities to play a leading role in this program, which subsequently advanced the Millennium Development Goals and Sustainable Development Goals. * In January 2002 the UN Commission on Human Settlements became an umbrella agency called the United Nations Human Settlements Programme or UN-Habitat, a member of the United Nations Development Group. * The Habitat III conference of 2016 focused on implementing these goals under the banner of a "New Urban Agenda". The four mechanisms envisioned for effecting the New Urban Agenda are (1) national policies promoting integrated sustainable development, (2) stronger urban governance, (3) long-term integrated urban and territorial planning, and (4) effective financing frameworks. Just before this conference, the European Union concurrently approved an "Urban Agenda for the European Union" known as the Pact of Amsterdam.Vanessa Watson, "Locating planning in the New Urban Agenda of the urban sustainable development goal"; ''Planning Theory'' 15(4), 2016; . UN-Habitat coordinates the UN urban agenda, working with the UN Environmental Programme, the UN Development Programme, the Office of the High Commissioner for Human Rights, the World Health Organization, and the

The bank's structural adjustment programs contributed to urbanization in the Third World by creating incentives to move to cities. The World Bank and UN-Habitat in 1999 jointly established the Cities Alliance (based at the World Bank headquarters in Washington, D.C.) to guide policymaking, knowledge sharing, and Grant (money), grant distribution around the issue of urban poverty.

Representation in culture

Cities figure prominently in traditional Western culture, appearing in the Bible in both evil and holy forms, symbolized by

. Cities can be perceived in terms of extremes or opposites: at once liberating and oppressive, wealthy and poor, organized and chaotic. The name anti-urbanism refers to various types of ideological opposition to cities, whether because of their culture or their political relationship with Rural area, the country. Such opposition may result from identification of cities with oppression and the ruling elite. This and other political ideologies strongly influence narratives and themes in discourse about cities. In turn, cities symbolize their home societies. Writers, painters, and filmmakers have produced innumerable works of art concerning the urban experience. Classical and medieval literature includes a genre of ''List of literary descriptions of cities (before 1550), descriptiones'' which treat of city features and history. Modern authors such as Charles Dickens and James Joyce are famous for evocative descriptions of their home cities. Fritz Lang conceived the idea for his influential 1927 film ''Metropolis (1927 film), Metropolis'' while visiting Times Square and marveling at the nighttime neon lighting. Other early cinematic representations of cities in the twentieth century generally depicted them as technologically efficient spaces with smoothly functioning systems of automobile transport. By the 1960s, however, traffic congestion began to appear in such films as ''The Fast Lady'' (1962) and ''Playtime'' (1967). Literature, film, and other forms of popular culture have supplied visions of future cities both utopian and dystopian. The prospect of expanding, communicating, and increasingly interdependent world cities has given rise to images such as Nylonkong (New York, London, Hong Kong) and visions of a single world-encompassing ecumenopolis.Constantinos Apostolou Doxiadis,
Ecumenopolis: Tomorrow's City
''; Britannica Book of the Year, 1968. Chapter V: Ecumenopolis, the Real City of Man. "Ecumenopolis, which mankind will have built 150 years from now, can be the real city of man because, for the first time in history, man will have one city rather than many cities belonging to different national, racial, religious, or local groups, each ready to protect its own members but also ready to fight those from other cities, large and small, interconnected into a system of cities. Ecumenopolis, the unique city of man, will form a continuous, differentiated, but also unified texture consisting of many cells, the human communities."
