With this maxim, Lefebvre crystallised roman stroganov live chart for binary options idea — one that he had done much to shape — that cities were no longer integral things but riven by a dualist logic of centre and periphery. This was not merely a spatial divide, of course, but a social one. Where the centre was supposedly a bastion of commerce, decision-making and wealth, the periphery was a sprawling hinterland of industry and proletarian housing or, at least, this is how things looked from his home in Paris.
A decade earlier, when he wrote The Urban Revolution, it had seemed to Lefebvre that this social rift was potentially revolutionary. In other words the city itself, and not industry, was now the crucible of social relations.
That view owes much to a particularly European conception of the city. The very notion of the centre is a historical fetish. It is heavily imbued with the aura of the Greek polis, the heart of the body politic, and with the idea of the medieval walled city as a self-contained citadel.
The centre conforms to an ideal of the city, one bedecked with squares and monuments. And these are atavistic images that we relinquish with great reluctance. The periphery, by contrast, is a relatively recent phenomenon.

And such images are loaded with prejudice. Periphery means immigration ethnic tension and poverty crime. The rings of tower blocks circling Paris and Milan have played the role of ghettos in the urban imaginary of those cities. Those same towers feed another image of the suburbs as repetitious landscapes, monocultures both architecturally and socially. Often cut off by orbital roads, they are considered transient zones that one passes through as you follow the signs for centre ville.
These products of standardised modernism were supposed to be the cities of the future, and their subsequent neglect and blighting lends them an air of failure.

For the artist Robert Smithson, the periphery was alive with weird potential. Inhis photo-essay A tour of the monuments of Passaic documented the very monuments that were supposed to be missing from the industrial hinterlands of New Jersey.
The post-industrial cities of the West have long-since discovered and exploited that industrial legacy. In America at that time, the suburbs were the boomtowns while the city centres were being abandoned to the poor. After the Watts riots ina million and a half residents left the fringes of downtown for the suburbs of Greater Los Angeles. And that was the story across the United States, with car-loving suburban sprawl being touted as the new urban ideal, while the crime-ridden inner cities were left to their own devices.

This was the case in London, too. And yet in the s it actively reversed that worrisome trend. The compact city was all of a sudden the sustainable city, the productive city and, in theory, the equitable city.

Such are the swings and roundabouts of urban attitudes from the mid to the late 20th century. The centre is taken for granted then vilified and then idealised once again. The periphery is by turns idealised, ghettoised and romanticised. But just as the fortunes of centres and peripheries have risen and fallen, their relationship is also undergoing dramatic changes.
The very centre-periphery dialectic is on the wane. But one above all will define the changing nature of that relationship, and that is that peripheries are the zones of growth. As we know, most urban growth this century will take place in the cities of the developing world. And, outside of China, most urbanisation is of the informal variety. Eighty-five per cent of all housing is built illegally by squatters.
By it is estimated that two billion people will be living in slums, mostly on urban peripheries. In other words, squatters are building the cities of tomorrow. Even now, cities such as Caracas can claim to be 60 per cent informal.
And while this has manifested itself as a city distinctly segregated between the formal centre and the informal periphery, that is not always the case. Rio for instance has 1, favelas, some of them in the city centre — the margins are not always on the periphery.
As the Mumbai-based urban anthropologists URBZ observed in Dharavi, to the slum-dwellers themselves the slum is always somewhere else. So where, we might ask, does the periphery start? The nature of mass urbanisation in the global south is one of the great social and logistical challenges of the century.
This is especially true in Africa, the first continent to experience mass urbanisation without industrialisation. One of the consequences will be the reconception of the city not as a planned entity but as a largely spontaneous one. In Latin America, which experienced mass urbanisation long before China or Africa, favelas and barrios are being recognised not as some kind of pre-formal city that is awaiting formalisation, but as bone fide pieces of the city in their own right — and that will have enormous consequences for the nature of the urban periphery.
With the compact city as our only sustainable option for urbanisation, it has become orthodoxy that cities cannot continue to sprawl in the manner that they did in the 20th century. And yet they must grow. The how to learn to trade of that will be the reimagining of peripheries as sites of enormous potential.
And as we absorb that challenge, the old certainties of centre and periphery will inevitably dissolve.

Enter suburbia Arguably, London invented the concept of the urban periphery, or at least one version of it. The nation that launched the industrial revolution would, naturally, beget the first megacity. At the turn of the 20th century London was the largest metropolis in the world, and it was a suburban city. The vast majority of the urban fabric was made up of two- and three-storey terrace houses stretching, from the centre, for 30km in every direction.
London invented suburbia, and with it urban sprawl. These suburbs are largely zones of middle-class comfort. Two factors above all make London an interesting case study.
The first is that precisely because of its ungainly size, it has always operated as a polycentric city. Instead, the periphery operates as a cluster of incorporated villages, each with its own high street or market as a commercial focal point. And this notion of polycentrism will be crucial to urban development in the 21st century.

Secondly, London has a clearly defined border. Implemented in as part of the Greater London Plan, the Green Belt remains off limits to new development, a natural straight jacket preventing the urban patient from munching all the daisies.
This was a bold strate! Tellingly, Medellin, in Colombia, is planning to implement a Green Belt, but it is considering doing so at the same time as creating a ring of transport infrastructure around the city that will only encourage its comunas, or informal settlements, to grow.
Those two policies will counteract each other, making the no-build zone impossible to police. What was a population of 8. Much as in America, this was a consequence of car culture and political neglect of the inner city. However, from the s London was to reverse that trend in dramatic fashion.
The centre was revived, particularly under the proposals of the Urban Task Force, chaired by Richard Rogers, which advocated higher density and more investment in public transport. These ideas represented a more truly urban vision than the quaint New Urbanism that had been advocating a return to the city in the US, and they were to have international influence.
London has been growing at pace over the last two decades, recovering the population size of its heyday. London is now a polyglot metropolis at the heart of a global economy.
And with that appeal comes new challenges for the periphery. With land in the city centre such a haven for roman stroganov live chart for binary options investment, the suburbs are coming under new strain. Traditionally, London has avoided the ghettoisation of the periphery, with the poor fairly evenly distributed across the city.
