an introduction to city diversity

Cities as seen from the street:

looking at the street, from the outskirts to the city centre,provides a good point of entry for examining the tissueand dynamics of a city, grasping its internai diversity, uncoveringcontrasts and convergences between cities, and exploring thesignificance of the urban .transformation from town to metropolis,to 'megacity'. Despite trends in globalization generating multipleslrnilarities, differences still remain considerable. Each city possessesits secret fabric, identir,able in a unique residentiat pattern, adaptingitself to the changing ti~es. The form of a street is reflectedin horizontal and vertical spatial expansion; juxtaposed residentialand commercial space; buildings which look inwards or outwards;street life and activities; street surface, vegetation and green areas;as weil as a degree of 'enclosure' for reasons of security.Ali provide good indicators in discovering and deepening the studyof city diversity (diversité citadine).

Modernism in Jakaru follows the city's majorarteries and big highways but stops short of spreading ailthe way through the branching alveolar structure sten-cilled on the land by the budding pattern of develop-ment. At these interstices, one enters into therealm of the semi-autonomous urban villages,where each community member lives in a Iittlehouse with red tiles, tightly bound ta ail theothers in a labyrinth of small pedestrian alley­ways. Rules exist with neighbourhood chiefs,organized curns of guard duty and a remarkabledomestic peace reigns in the heart of a metrop­olis which, on a number of other fronts, con­

Abidjan,shared space. Around

the capital of the Côte d'Ivoire,

the court is the key ta an

undersranding of the popular

habitat. Parcels of land, distrib­

uted by the colonial adminis­

tration, were large enough ro

accommodate an entire ext­

ended family but came ta be

rapidly organized during con­

ditions of growing demand,

into a system of rented courts.

Gradually, the model of an

open-plan family court rook

shape, with eight ta ten

domestic units grouped aro­

und a single mango tree. After

independence, public habitat

programmes then promoted a

more modern model of smaller individual courts. Over the last ten years, the [wo

models have been merging: court areas have been compartmentalizing, the com­

mon mango tree has disappeared but the street, convivial as ever, remains the

setting for quiet games of ludo, draughts or the popular game of table football.

Dakar, divided space. In the 1960s and 1970s, the city of Dakar decid­

ed to rid itself of the precarious shelters which had spread through ail but the

ciéy's tiniest cracks. In order to rehouse the displaced population, cursory plots .

were allocated 30 km away in

Pikine, whose identity was cast

as Dakar's surrogate shadow.

Today, the Senegalese capital

is suffocating from a malaise

even more intense with the

generalized propagation of the

informai economy: Not built

with this in mind, Dakar is

being stifled, while Pikine

seems to be drawing in ail the

vitality of a big city. A sweet

revenge?

II1II Cairo,prohibited space. With

its back right up against harsh

desert plateaux, Cairo is con­

tinually edging ever further imo

the agricultural lands of the

Delta, where new roads roll

out over the lines of irrigation

ditches. Yet, paradoxically,

these pieces of land are pro­

tected twice over: once by a

State, keen to preserve them

and tyylce by the high costs of

land. The desert, traditionally

reserved for bu rials, can only

attract insufficient public

investmenc. The end result for

the wetter areas is the profu­

sion of an extraordinarily dense

human habitat of narrow

streets lik~ vertical canyons,

where ail the urban functions

rub shoulders with each other.

Manaus,pioneer space. Capital of Amazonia, Man­

aus is at the centre of a vast green mosaic. Here,

the 'founding aa' for any locale must therefore be

the staking out of land by chopping and clearing.

This pioneer experience, even when it is orches­

trated by illegal plot-holders, instils a powerful

feeling of ownership and belonging. Lower-Iying areas are prone ta periodic f1ooding, however, so Man­

aus advances like a flea, 'jumping' between interiluvial higher ground. large swathes of tropical forest

are ignored in the process and, as a consequence, latecomer migrants will nonetheless popufate the

folds of the tawn with impermanent shelters on stilts.

Nouakchott, exposed space. Thirty years

ago, Nouakchott did not even exist: the outpost had only

just been made the capital of the Mauritanian Desert.

Today, Nouakchott has some 600,000 in habitants, plucked

from a nation with a population of fewer than two million

people, who ho Id no previous experience of urban living.

Around the administrative districts, the desert is bare and

the arrivais to the city are impoverished nomads who have

congregated together in encampments of canvas and loose

planks. Every now and then, the Government sends

out a team of land surveyors ta skirt around

the huts and trace out the streets.

Thus grows the city.

Sao Paolo, laminated space. Not so long ago, sao Paulo became one of the world's largest cities.

With over 20 million people, its demographic momentum has cut imo traditional residential patterns like a deep

blade. Cultural acr:achments to the ideal of a detached house are put under strain. Many of the rich escape the

nuisances of the city in

the 'third dimension',

upwards in one of the

18,000 tower blocks

which punctuate Sao

Paulo's heritage of

baroque villas. The

poor are solicited

more and more by

those poorer still to

lease their courtyards

or add another floor.

Laundry dries on cem­

ent roofs forever on

the verge of another

elevation. Roof tlles

and gardens disappear.

Recife, undulating space. The suburbs of old Pernambouc resemble rolling waves on the ocean sur­

face. In this desolate region of the Nordeste, the majority of the poor (both black and white) construa small

clay and tile houses. a1ways surrounded by a garden, on the f1anks of the undulating hills. Access is by foot, up long

flights of steps scaling each hill, or morro. The steps, rising vertically Iike zebra's stripes from the main street which

stretches the length of each val­

ley depression, go up to anoth­

er street running along the

crest of the hills. Inhabitants

idemify themselves ta their

morro and the single main street

that services neighbourhood

shops and outlets. Buses come

ta a hait at the end of each of

these streets, turn around and

go back: an example of frag­

mentation moulded by a public

transport system.

Berlin, liberated space. Redesigned in the midst of the classic period, Berlin

is the most generous of the European capitals in its share of open spaces, avenues and

visCls. However, the nineteenth century practice of leasing Mietskasernen - rented

accommodation in apartment blocks overlooking a courtyard, with one courtyard giv­

ing way to another on the same plot of land - led to an excessive dividing up of the

'islets' planned as living space. From 1945 onwards, West Berlin broke down the sub­

divisions and aired out the residential tissue by injeeting light, colour, trees. gardens and

games for children into the islets. Since the collapse of

the Wall. this work has been carried through to

the East Reunification equally has opened

up vast areas of no man's land

which, roday, are the targets

of ambitious new pro­

jeets in urbanism.

Sofia, frayed space. At the hearr of the Balkans, the Bulgarian capitalillus­

trates weil the fate of a late adept to West European urban models, swept up almost

straight away by a Soviet urban mould and now proceeding to reflect on its situation.

Stalinist architecture has marked the city centre only moderately but the spoliation

left the post-Haussmanian bourgeois buildings considerably run down. The balance

sheet is most serious in the periphery's komplex, which ought perhaps to be torn

down, yet remain indispensable lodgings for the majority. Green spaces are only

indefrnite patches where, roday.

improvlSed boutiques floumh.

The most enterprising of the

city dwellers live in the pavil­

ioned suburbs where, on Sun­

days, they build and rebuild, and

in their square of garden, plant

potatoes and lettuces behind a

few tulips.

Li ma, heroic space. Basking in an oasis. Lima

once proudly cultivated its Andalusian and Creole tradi­

tions. Yet, since 1950. a megalopolization of the city has

precipitated a pauperised Andean population, unable to

find a place inside the oasis. Most of the eight million

Andeans are confrned ro the outer fringes and Lima has

become a metropolis of the desert. Still, behind the

extreme desolation of the barriadas, authentic urban

projects. both individual and community-based, can be

made out. The lack of water is confronted with heroism.

The unique advantage of the situation, the inexpen­

siveness of this unproductive land, has been

exploited ta the full: everyone has a

spacious plot and sports areas

are plentiful.

• Rio de Janeiro, inaccessible space. It

would be wrong ro reduce Rio de Janeiro ro a cliché post­

card image of the close proximity of miserable (avellas

overshadowing the rich along the beach. The bulk of the

population is engaged in a never-ending patchwork of inva­

sions and re-allocations of plots, blurring constantly the

nuances bet'Heen poor and median classes. However, it is

true that the corioco siums are the stereotype, c1inging ta

the near-vertical siopes of the sugar loaf rocks around the

bay. Yet it does not seem ta be the disparity in wealth that

fascinates but rather the menacing atmosphere of intangi­

ble reminders, in che very hearr of the city, which drug

gangs have sown in Rio for the last t'Henty years.

Milan, circular space. Milan spreads out in three (almost perfectly

concentric) rings, passed down from the thirteenth, sixteenth and nineteenth cen­

turies, with the Pi=a dei Duarno at the centre. Beyond the third ring, this regularity in

the metropolitan ambiance breaks down, yet the genius of Milan is to have known

how to retain the fragile f10wer of its bourgeoisie within its innermosc circle. Nerther

the miniature palaces, coiled

around central courcyards, nor

the living quarters which look in

on closed gardens and courtS,

have succumbed to becoming

office blacks or towers. This

taste for an introverted city life

is retraced in the wider dis­

tricts, where individu al pavilions

are rare and where collective

housing estates are grouped

upon themselves, for example

around a central internai space.

Meeting point in Los Angeles. Paradise for some, for others Los Angeles has become a

nightmare conurbation sprawling out over hundreds of kilometr.es, from Santa Barbara to the Mexican bor­

der. Envisaged for couples with a private house, an automobile or a mobile-home, ewo-thirds of the built

environ ment in Los Angeles is dedicated ta the system of roads and parking (as opposed to one-third in

Paris and one-tenth in Jakarta). The distances can be exhausting for the inhabitants and associative activities

(e.g. relating ta neighbourhood or leisure aetivities) fail ta conceal the hollowness of much of this diffused

urban tissue: added to shortages ofwater, air pollution, seismic aetivity and eruptions of violence, there has

been the recent transformation of the Californian economy, resulting in thousands of homeless people liv­

ing in the streets out of a shopping trolley. And yet this westernmost tip of the West continues (Q feed the

dreams of America. The race to the West is still on - redoubled, in face, by an insatiable quest for the sun
