Slum Ecology
by MIKE DAVIS

A VILLA MISERIA OUTSIDE Buenos Aires may have the worst feng shui
in the world: it is built in a flood zone over a former lake, a toxic dump, and
a cemetery. Then there’s the barrio perched precariously on stilts over the
excrement-clogged Pasig River in Manila, and the bustee in Vijayawada that
floods so regularly that residents have door numbers written on pieces of

furniture. In slums the world over, squatters trade safety and health for a
few square meters of land and some security of tenure. They are pioneers of
swamps, floodplains, volcano slopes, unstable hillsides, desert fringes,
railroad sidings, rubbish mountains, and chemical dumps — unattractive
and dangerous sites that have become poverty’s niche in the ecology of the
city.

Cities have absorbed nearly two-thirds of the global population explosion
since 1950, and are currently adding a million babies and migrants each
week. Dhaka, Kinshasa, and Lagos today are each approximately forty times
larger than they were in 1950. According to the Financial Times, China in
the 1980s alone added more city dwellers than did all of Europe (including
Russia) during the entire nineteenth century.

In this process of rampant urbanization, the planet has become marked by
the runaway growth of slums, characterized by overcrowding, poor or
informal housing, inadequate access to safe water and sanitation, and
insecurity of tenure. UN researchers estimate that there were at least 921
million slum dwellers in 2001 and more than 1 billion in 2005, with slum
populations growing by a staggering 25 million per year.

Today, new arrivals to the urban margin confront a condition that can only
be described as marginality within marginality, or, in the more piquant
phrase of a desperate Baghdad slum dweller quoted by The New York Times,
a “semi-death.” An International Labor Organization researcher has
estimated that the formal housing markets in the Third World rarely supply
more than 20 percent of new housing stock; out of necessity, people turn to
self-built shanties, informal rentals, pirate subdivisions, or the sidewalks.
These are moves of sheer survival. And because the geographic location of
slums is becoming more and more marginal, the destructive power of
natural elements leaves today’s slum residents in an ever more vulnerable
state.

Slums begin with bad geology. Johannesburg’s shantytown periphery, for
example, conforms unerringly to a belt of dangerous, unstable dolomitic
soil contaminated by generations of mining. At least half of the region’s
nonwhite population lives in informal settlements in areas of toxic waste
and chronic ground collapse. Likewise, the highly weathered lateritic soils
underlying hillside favelas in Belo Horizonte and other Brazilian cities are
catastrophically prone to slope failure and landslides. Rio de Janeiro’s more
famous favelas are built on equally unstable soils atop denuded granite
domes and hillsides that frequently give way — with deadly results.

Caracas, however, with a population of 5.2 million in 2005, is the soil
geologist’s “perfect storm”: slums housing almost two-thirds of the city’s
population are built on unstable hillsides and in deep gorges surrounding
the seismically active Caracas Valley. At one time vegetation held the friable
schist in place, but brush clearing and cut-and-fill construction have
destabilized the densely inhabited hills and precipitated a radical increase in
major landslides and slope failures — from less than one per decade before
1950 to the current average of two or more per month.

In mid-December 1999, an extraordinary storm clobbered northern
Venezuela. A year’s worth of rain fell in a few days upon already saturated
soil; indeed, rainfall in some areas was reckoned to be a once-in-a-
millennium event. The result was flash floods and debris flows in Caracas
— and along the Caribbean coast on the other side of the Avila Mountains,
where an onrush of 1.8 million tons of debris left the coastal resort of
Caraballeda devastated. The storm killed an estimated 32,000 people and
left 140,000 homeless and another 200,000 jobless.

What the Caracas region is to landslides, metropolitan Manila is to frequent
flooding. In July 2000 a typhoon deluge caused the collapse of a notorious
“garbage mountain” in Quezon City’s Payatas slum, burying five hundred
shacks and killing at least a thousand people.

Earthquakes make even more precise audits of the urban housing crisis;
seismic hazard is the fine print in the devil’s bargain of “informal” housing
marked by poor construction. Seismic destruction usually maps poor-
quality brick, mud, or concrete residential housing with uncanny accuracy.

But the urban poor do not lose much sleep at night worrying about
earthquakes or even floods. Their chief anxiety is a more frequent and
omnipresent threat: fire. Slums, not Mediterranean brush or Australian
eucalyptuses, are the world’s premier fire ecology. Their mixture of
flammable dwellings, extraordinary density, and dependence upon open
fires for heat and cooking is a superlative recipe for spontaneous
combustion. A simple accident with cooking gas or kerosene can quickly
become a megafire that destroys hundreds or even thousands of dwellings.
Fire spreads through shanties at stunning velocity, and fire-fighting
vehicles, if they respond at all, are often unable to negotiate narrow slum
lanes.

To make matters worse, slum fires are often anything but accidents. Rather
than bear the expense of court procedures or endure the wait for an official
demolition order, landlords and developers frequently prefer the simplicity
of arson. Manila has a particularly notorious reputation for suspicious slum
fires, especially in areas targeted for industrial development. Urban
sociologist Erhard Berner describes a favorite method of Filipino landlords:
to chase a “kerosene-drenched burning live rat or cat — dogs die too fast —
into an annoying settlement… The unlucky animal can set plenty of
shanties aflame before it dies.”

ALL THE CLASSICAL PRINCIPLES of urban planning, including the
preservation of open space and the separation of noxious land uses from
residences, are stood on their heads in poor cities. Almost every large Third
World city with some industrial base has a Dantean district shrouded in
pollution and located next to pipelines, chemical plants, and refineries:
Mexico City’s Iztapalapa, São Paulo’s Cubatão, Rio’s Belford Roxo, Jakarta’s

9/29/2020 Orion Magazine | Slum Ecology

Cibubur, Tunis’s southern fringe, southwestern Alexandria, and so on. The
world usually pays attention to such fatal admixtures of poverty and toxic
industry only when they explode with mass casualties, as happened at
Bhopal, India, in 1984, when an accident at a Union Carbide chemical plant
killed twenty thousand people.

Urban theorists have long recognized that the environmental efficiency and
public affluence of cities require the preservation of ecosystems, open
spaces, and natural services: cities need them to recycle urban waste
products into usable inputs for farming, gardening, and energy production.
And along with intact wetlands and agriculture, sustainable urbanism
presupposes a basic level of safety — of meteorological, hydrological, and
geological stability, and protection against disasters like floods or fire. None
of those conditions can hold in most Third World cities. Suffering under a
series of crushing pressures, most recently a quarter-century-old regime of
Draconian international economic policies, cities are systematically
polluting, urbanizing, and destroying their crucial environmental support
systems.

Wealthy cities in vulnerable sites such as Los Angeles or Tokyo can reduce
geological or meteorological risk through massive engineering projects.
And national flood insurance programs, together with fire and earthquake
insurance, can guarantee residential repair and rebuilding in the event of
extensive damage. In the Third World, by contrast, slums that lack potable
water and latrines are unlikely to be defended by expensive public works or
covered by disaster insurance. Researchers writing in the journal Cities
point out that foreign debt makes such infrastructure investment ever more
unlikely. “Structural adjustment” — the protocols by which indebted
countries surrender their economic independence to the World Bank and
International Monetary Fund (IMF) — drives sinister trade-offs that favor
export-oriented production, competition, and efficiency at the expense of
disaster-vulnerable settlements.

THE GLOBAL FORCES pushing people from the countryside seem to
sustain urbanization even when the pull of the city is drastically weakened
by debt and economic depression.

As Deborah Bryceson emphasizes in her summary of recent agrarian
research, the IMF and World Bank policies of the 1980s and 1990s caused
unprecedented upheaval in the global countryside. One by one, she writes,
national governments gripped in debt lost access to agricultural subsidies
and support for rural infrastructure. Latin American and African nations
abandoned peasant “modernization” efforts and deregulated national
markets, subjecting peasant farmers to the “sink-or-swim” economic
strategy of international financial institutions. Pushed into global
commodity markets, agricultural producers found it hard to compete.

These anti-peasant policies had the same results throughout much of the
developing world. As local safety nets disappeared, poor farmers became
increasingly vulnerable to any exogenous shock: drought, inflation, rising
interest rates, or falling commodity prices. (Or illness: an estimated 60
percent of Cambodian peasants who sell their land and move to the city are
forced to do so by medical debts.) Meanwhile, rapacious warlords and
chronic civil wars, often spurred by the economic dislocations of debt-
imposed structural adjustment or foreign economic predators (as in the
Congo and Angola), were uprooting whole countrysides. Cities — in spite of
their stagnant or negative economic growth — have simply harvested this
world agrarian crisis. Peasants had no choice but to become urban.

The fallout has been predictable: hundreds of millions of new urbanites
must further subdivide the peripheral economic niches of personal service,
casual labor, street-vending, ragpicking, begging, and crime. With its high-
tech border enforcement blocking large-scale migration to the rich
countries, the new world order has dictated a formula for the mass
production of slums, and for rising suffering from flood, slides, quakes, and
fire.

But of all the dangerous ecological symptoms of runaway urban poverty,
none poses a bigger threat than overflowing waste. The chronic shortfalls
between the rates of trash generation and disposal in Third World cities are
often staggering: the average collection rate in Dar es Salaam is barely 25
percent; in Karachi, 40 percent; and in Jakarta, 60 percent. The city
planning director in Kabul complained to the Washington Post that his city
is becoming “one big reservoir of solid waste… Every 24 hours, 2 million
people produce 800 cubic meters of solid waste. If all 40 of our trucks make
three trips a day, they can still transport only 200 to 300 cubic meters out of
the city.”

Outside Hanoi, where farmers and fishermen are constantly uprooted by
urban development, urban and industrial effluents are now routinely
employed as free substitutes for artificial fertilizers. When researchers
writing for the journal Environment and Urbanization questioned this
noxious practice, they discovered cynicism among vegetable and fish
producers about the “rich people” in cities. “They don’t care about us and
fool us with useless compensation [for farm land],” as one purveyor put it,
“so why not take some form of revenge?”

The subject of human waste is, of course, indelicate; but it is a fundamental
problem of city life from which there is surprisingly little escape. Lovly
Josaphat, a resident of Port-au-Prince’s largest slum, Cité Soleil, told author
Beverly Bell, “I’ve suffered a lot. When it rains, the part of the Cité I live in
floods and the water comes in the house. There’s always water on the
ground, green smelly water, and there are no paths. The mosquitoes bite us.
My four-year-old has bronchitis, malaria, and even typhoid now… The doctor
said to give him boiled water, not to give him food with grease, and not to
let him walk in the water. But the water’s everywhere; he can’t set foot
outside the house without walking in it. The doctor said that if I don’t take
care of him, I’ll lose him.”

9/29/2020 Orion Magazine | Slum Ecology

Green, smelly water everywhere. “Every day, around the world,” according to
public-health expert Eileen Stillwaggon, “illnesses related to water supply,
waste disposal, and garbage kill thirty thousand people and constitute 75
percent of the illnesses that afflict humanity.” Indeed, digestive-tract
diseases arising from poor sanitation and the pollution of drinking water
are the leading cause of death in the world, affecting mainly infants and
small children. Open sewers and contaminated water are likewise rife with
intestinal parasites such as whipworm, roundworm, and hookworm that
infect tens of millions of children in poor cities. Cholera, the scourge of the
Victorian city, continues to thrive off the fecal contamination of urban water
supplies, especially in African cities like Antananarivo, Maputo, and Lusaka,
where UNICEF estimates that up to 80 percent of deaths from preventable
diseases (apart from HIV/AIDS) arise from poor sanitation.

“At any one time,” adds a 1996 report by the World Health Organization,
“close to half of the South’s urban population is suffering from one or more
of the main diseases associated with inadequate provision for water and
sanitation.” Although clean water is the cheapest and single most important
medicine in the world, public provision of water remains widely inadequate,
and often competes with powerful private interests. In Dhaka, vendors
mark up the cost of water — often from municipal sources — by 500
percent; in Faisalabad, 6,800 percent. Unable or unwilling to pay the
extortionate price of water from vendors, some Nairobi residents resort to
desperate expedients, including, two local researchers write, “the use of
sewerage water, skipping bathing and washing, using borehole water and
rainwater, and drawing water from broken pipes.”

WHILE THE RESTRUCTURING of Third World urban economies has
contributed to dangerous health conditions it has also gutted the response
to those conditions. Since the late 1970s, international economic policy has
devastated the public provision of healthcare, particularly for women and
children. As the Women’s Global Network for Reproductive Rights points
out, structural adjustment programs “usually require public spending,

9/29/2020 Orion Magazine | Slum Ecology

https://orionmagazine.org/article/slum-ecology/ 9/10

including health spending (but not military spending) to be cut.” In Latin
America and the Caribbean, according to a World Bank researcher, the
enforced austerity during the 1980s reduced public investment in sanitation
and potable water, thus eliminating the infant survival advantage previously
enjoyed by poor urban residents. In Mexico, following the adoption of a
second adjustment program in 1986, the percentage of births attended by
medical personnel fell from 94 percent in 1983 to 45 percent in 1988, while
maternal mortality soared from 82 per 100,000 in 1980 to 150 in 1988.

In Ghana, “adjustment” not only led to an 80 percent decrease in spending
on health and education between 1975 and 1983, it also caused the exodus
of half of the nation’s doctors. Similarly, in the Philippines in the early
1980s, per capita health expenditures fell by half. In oil-rich but thoroughly
“adjusted” Nigeria, a fifth of the country’s children now die before age five.
Economist Michel Chossudovsky blames the notorious outbreak of bubonic
plague in Surat in 1994 upon “a worsening urban sanitation and public
health infrastructure which accompanied the compression of national and
municipal budgets under the 1991 IMF/World Bank-sponsored structural
adjustment programme.”

The examples can easily be multiplied: everywhere, obedience to
international creditors, whose policies helped create slums in the first place,
has dictated cutbacks in medical care and precipitated the emigration of
doctors and nurses, the end of food subsidies, and the switch of agricultural
production from subsistence to export crops.

More recently the World Bank has relentlessly pressured aid recipients to
open themselves to global competition from private First World healthcare
providers and pharmaceutical companies. The Bank’s 1993 “Investing in
Health” report outlined the new paradigm of market-based healthcare, as
described by Fantu Cheru, a leading UN expert on debt: “limited public
expenditure on a narrowly defined package of services; user fees for public
services; and privatized health care and financing.” A sterling instance of

9/29/2020 Orion Magazine | Slum Ecology

https://orionmagazine.org/article/slum-ecology/ 10/10

the new approach was Zimbabwe, where the introduction of user fees in the
early 1990s led to a doubling of infant mortality. As Cheru emphasizes, the
coerced tribute that the Third World pays to the First World has meant the
literal difference between life and death for millions of poor people.

But if ecological reality prevails, it won’t stop there. Today’s megaslums are
unprecedented incubators of new and re-emergent diseases that can travel
across the world at the speed of a passenger jet. And, as the imminent peril
of avian influenza indicates, economic globalization without concomitant
investment in a global public-health infrastructure is a formula for
catastrophe. It takes only a little imagination — the thought of a series of ill-
fated airplane trips — to remind us that we’re all living on the same planet
of slums, under the same economic regime. The conditions creating the
slums — greed, inequity, poor planning, and disrespect for human rights
— are human forces, but they tend to intensify the Earth’s natural forces.
Those forces, ecological and biological, don’t always behave as predictably as
we would like, or stay within their bounds.

PLANET OF SLUMS

Urban Involution and the Informal Proletariat

Sometime in the next year, a woman will give birth in the
Lagos slum of Ajegunle, a young man will flee his village
in west Java for the bright lights of Jakarta, or a farmer will
move his impoverished family into one of Lima’s innumerable

pueblos jovenes. The exact event is unimportant and it will pass entirely
unnoticed. Nonetheless it will constitute a watershed in human history.
For the first time the urban population of the earth will outnumber
the rural. Indeed, given the imprecisions of Third World censuses, this
epochal transition may already have occurred.

The earth has urbanized even faster than originally predicted by the
Club of Rome in its notoriously Malthusian 1972 report, Limits of
Growth. In 1950 there were 86 cities in the world with a population
over one million; today there are 400, and by 2015, there will be at
least 550.1 Cities, indeed, have absorbed nearly two-thirds of the global
population explosion since 1950 and are currently growing by a million
babies and migrants each week.2 The present urban population (3.2 bil-
lion) is larger than the total population of the world in 1960. The global
country side, meanwhile, has reached its maximum population (3.2 bil-
lion) and will begin to shrink after 2020. As a result, cities will account
for all future world population growth, which is expected to peak at
about 10 billion in 2050.3

Where are the heroes, the colonisers, the victims of the Metropolis?
Brecht, Diary entry, 1921

Ninety-five per cent of this final buildout of humanity will occur in the
urban areas of developing countries, whose population will double to
nearly 4 billion over the next generation.4 (Indeed, the combined urban
population of China, India and Brazil already roughly equals that of
Europe plus North America.) The most celebrated result will be the
burgeoning of new megacities with populations in excess of 8 million,
and, even more spectacularly, hypercities with more than 20 million
inhabitants (the estimated urban population of the world at the time of
the French Revolution).5 In 1995 only Tokyo had incontestably reached
that threshold. By 2025, according to the Far Eastern Economic Review,
Asia alone could have ten or eleven conurbations that large, including
Jakarta (24.9 million), Dhaka (25 million) and Karachi (26.5 million).
Shanghai, whose growth was frozen for decades by Maoist policies of
deliberate under-urbanization, could have as many as 27 million resi-
dents in its huge estuarial metro-region.6 Mumbai (Bombay) meanwhile
is projected to attain a population of 33 million, although no one knows
whether such gigantic concentrations of poverty are biologically or eco-
logically sustainable.7

5 Although the velocity of global urbanization is not in doubt, the growth rates of
specific cities may brake abruptly as they encounter the frictions of size and cong-
estion. A famous instance of such a ‘polarization reversal’ is Mexico City: widely
predicted to achieve a population of 25 million during the 1990s (the current popu-
lation is probably about 18 or 19 million). See Yue-man Yeung, ‘Geography in an

But if megacities are the brightest stars in the urban firmament, three-
quarters of the burden of population growth will be borne by faintly visible
second-tier cities and smaller urban areas: places where, as un research-
ers emphasize, ‘there is little or no planning to accommodate these people
or provide them with services.’8 In China (officially 43 per cent urban in
1997), the number of official cities has soared from 193 to 640 since 1978.
But the great metropolises, despite extraordinary growth, have actually
declined in relative share of urban population. It is, rather, the small cities
and recently ‘citized’ towns that have absorbed the majority of the rural
labour-power made redundant by post-1979 market reforms.9 In Africa,
likewise, the supernova-like growth of a few giant cities like Lagos (from
300,000 in 1950 to 10 million today) has been matched by the trans-
formation of several dozen small towns and oases like Ouagadougou,
Nouakchott, Douala, Antananarivo and Bamako into cities larger than
San Francisco or Manchester. In Latin America, where primary cities long
monopolized growth, secondary cities like Tijuana, Curitiba, Temuco,
Salvador and Belém are now booming, ‘with the fastest growth of all
occurring in cities with between 100,000 and 500,000 inhabitants.’10

Moreover, as Gregory Guldin has urged, urbanization must be concep-
tualized as structural transformation along, and intensified interaction
between, every point of an urban–rural continuum. In his case-study
of southern China, the countryside is urbanizing in situ as well as
genera ting epochal migrations. ‘Villages become more like market and
xiang towns, and county towns and small cities become more like
large cities.’ The result in China and much of Southeast Asia is a
hermaphro ditic landscape, a partially urbanized countryside that Guldin
and others argue may be ‘a significant new path of human settlement
and develop ment . . . a form neither rural nor urban but a blending
of the two wherein a dense web of transactions ties large urban cores
to their surrounding regions.’11 In Indonesia, where a similar process

of rural/urban hybridization is far advanced in Jabotabek (the greater
Jakarta region), researchers call these novel land-use patterns desokotas
and debate whether they are transitional landscapes or a dramatic new
species of urbanism.12

Urbanists also speculate about the processes weaving together Third
World cities into extraordinary new networks, corridors and hierarchies.
For example, the Pearl River (Hong Kong–Guangzhou) and the Yangtze
River (Shanghai) deltas, along with the Beijing–Tianjin corridor, are
rapidly developing into urban-industrial megalopolises comparable to
Tokyo–Osaka, the lower Rhine, or New York–Philadelphia. But this may
only be the first stage in the emergence of an even larger structure:
‘a continuous urban corridor stretching from Japan/North Korea to
West Java.’13 Shanghai, almost certainly, will then join Tokyo, New York
and London as one of the ‘world cities’ controlling the global web of
capital and information flows. The price of this new urban order will
be increasing inequality within and between cities of different sizes and
specializations. Guldin, for example, cites intriguing Chinese discus-
sions over whether the ancient income-and-development chasm between
city and countryside is now being replaced by an equally fundamental
gap between small cities and the coastal giants.14

2. back to dickens

I saw innumerable hosts, foredoomed to darkness, dirt, pestilence,
obscenity, misery and early death.

Dickens, ‘A December Vision’, 1850

The dynamics of Third World urbanization both recapitulate and con-
found the precedents of nineteenth and early twentieth-century Europe
and North America. In China the greatest industrial revolution in history
is the Archimedean lever shifting a population the size of Europe’s from

rural villages to smog-choked sky-climbing cities. As a result, ‘China
[will] cease to be the predominantly rural country it has been for millen-
nia.’15 Indeed, the great oculus of the Shanghai World Financial Centre
may soon look out upon a vast urban world little imagined by Mao or,
for that matter, Le Corbusier. But in most of the developing world, city
growth lacks China’s powerful manufacturing-export engine as well as
its vast inflow of foreign capital (currently equal to half of total foreign
investment in the developing world).

Urbanization elsewhere, as a result, has been radically decoupled from
industrialization, even from development per se. Some would argue
that this is an expression of an inexorable trend: the inherent tendency
of silicon capitalism to delink the growth of production from that of
employment. But in sub-Saharan Africa, Latin America, the Middle
East and parts of Asia, urbanization-without-growth is more obviously
the legacy of a global political conjuncture—the debt crisis of the late
1970s and subsequent imf-led restructuring of Third World economies
in the 1980s—than an iron law of advancing technology. Third World
urbanization, moreover, continued its breakneck pace (3.8 per cent per
annum from 1960–93) through the locust years of the 1980s and early
1990s in spite of falling real wages, soaring prices and skyrocketing
urban unemployment.16

This ‘perverse’ urban boom contradicted orthodox economic models
which predicted that the negative feedback of urban recession should
slow or even reverse migration from the countryside. The African case
was particularly paradoxical. How could cities in Côte d’Ivoire, Tanzania,
Gabon and elsewhere—whose economies were contracting by 2 to 5 per
cent per year—still sustain population growth of 5 to 8 per cent per

15 Wang Mengkui, advisor to the State Council, quoted in the Financial Times, 26
November 2003. Since the market reforms of the late 1970s it is estimated that
almost 300 million Chinese have moved from rural areas to cities. Another 250
or 300 million are expected to follow in coming decades. (Financial Times, 16

annum?17 Part of the secret, of course, was that imf- (and now wto-)
enforced policies of agricultural deregulation and ‘de-peasantization’
were accelerating the exodus of surplus rural labour to urban slums even
as cities ceased to be job machines. Urban population growth in spite
of stagnant or negative urban economic growth is the extreme face of
what some researchers have labelled ‘over-urbanization’.18 It is just one
of the several unexpected tracks down which a neoliberal world order
has shunted millennial urbanization.

Classical social theory from Marx to Weber, of course, believed that the
great cities of the future would follow in the industrializing footsteps of
Manchester, Berlin and Chicago. Indeed, Los Angeles, São Paulo, Pusan
and, today, Ciudad Juárez, Bangalore and Guangzhou, have roughly
approximated this classical trajectory. But most cities of the South are
more like Victorian Dublin which, as Emmet Larkin has emphasized,
was unique amongst ‘all the slumdoms produced in the western world in
the nineteenth century . . . [because] its slums were not a product of the
industrial revolution. Dublin, in fact, suffered more from the problems of
de-industrialization than industrialization between 1800 and 1850.’19

Likewise Kinshasa, Khartoum, Dar es Salaam, Dhaka and Lima grow
prodi giously despite ruined import-substitution industries, shrunken
public sectors and downwardly mobile middle classes. The global forces
‘pushing’ people from the countryside—mechanization in Java and India,
food imports in Mexico, Haiti and Kenya, civil war and drought through-
out Africa, and everywhere the consolidation of small into large holdings
and the competition of industrial-scale agribusiness—seem to sustain
urbanization even when the ‘pull’ of the city is drastically weakened by
debt and depression.20 At the same time, rapid urban growth in the context

toward ‘under-urbanization’.

of structural adjustment, currency devaluation and state retrenchment
has been an inevitable recipe for the mass production of slums.21 Much of
the urban world, as a result, is rushing backwards to the age of Dickens.

The astonishing prevalence of slums is the chief theme of the historic
and sombre report published last October by the United Nations’
Human Settlements Programme (un-Habitat).22 The Challenge of the
Slums (henceforth: Slums) is the first truly global audit of urban poverty.
It adroitly integrates diverse urban case-studies from Abidjan to Sydney
with global household data that for the first time includes China and
the ex-Soviet Bloc. (The un authors acknowledge a particular debt to
Branko Milanovic, the World Bank economist who has pioneered the
use of micro-surveys as a powerful lens to study growing global inequal-
ity. In one of his papers, Milanovic explains: ‘for the first time in human
history, researchers have reasonably accurate data on the distribution of
income or welfare [expenditures or consumption] amongst more than
90 per cent of the world population.’)23

Slums is also unusual in its intellectual honesty. One of the researchers
associated with the report told me that ‘the “Washington Consensus”
types (World Bank, imf, etc.) have always insisted on defining the prob-
lem of global slums not as a result of globalization and inequality but
rather as a result of “bad governance”.’ The new report, however, breaks
with traditional un circumspection and self-censorship to squarely indict
neoliberalism, especially the imf’s structural adjustment programmes.24
‘The primary direction of both national and international interventions
during the last twenty years has actually increased urban poverty and
slums, increased exclusion and inequality, and weakened urban elites in
their efforts to use cities as engines of growth.’25

countries.

countries’ debts’. See The State of the World’s Children, Oxford 1989, p. 30.

Slums, to be sure, neglects (or saves for later un-Habitat reports) some of
the most important land-use issues arising from super-urbanization and
informal settlement, including sprawl, environmental degradation, and
urban hazards. It also fails to shed much light on the processes expelling
labour from the countryside or to incorporate a large and rapidly grow-
ing literature on the gender dimensions of urban poverty and informal
employment. But these cavils aside, Slums remains an invaluable exposé
that amplifies urgent research findings with the institutional authority
of the United Nations. If the reports of the Intergovernmental Panel
on Climate Change represent an unprecedented scientific consensus on
the dangers of global warming, then Slums sounds an equally authori-
tative warning about the global catastrophe of urban poverty. (A third
report someday may explore the ominous terrain of their interaction.)26
And, for the purposes of this review, it provides an excellent framework
for reconnoitering contemporary debates on urbanization, the informal
economy, human solidarity and historical agency.

3. the urbanization of poverty

The mountain of trash seemed to stretch very far, then gradually
without perceptible demarcation or boundary it became something else.
But what? A jumbled and pathless collection of structures. Cardboard
cartons, plywood and rotting boards, the rusting and glassless shells of
cars, had been thrown together to form habitation.

Michael Thelwell, The Harder They Come, 1980

The first published definition of ‘slum’ reportedly occurs in Vaux’s 1812
Vocabulary of the Flash Language, where it is synonymous with ‘racket’ or
‘criminal trade’.27 By the cholera years of the 1830s and 1840s, however,
the poor were living in slums rather than practising them. A generation
later, slums had been identified in America and India, and were gen-
erally recognized as an international phenomenon. The ‘classic slum’
was a notoriously parochial and picturesquely local place, but reformers
generally agreed with Charles Booth that all slums were characterized
by an amalgam of dilapidated housing, overcrowding, poverty and vice.
For nineteenth-century Liberals, of course, the moral dimension was

26 Such a study, one supposes, would survey, at one end, urban hazards and infra-
structural breakdown and, at the other, the impact of climate change on agriculture
and migration.

decisive and the slum was first and above all envisioned as a place where
a social ‘residuum’ rots in immoral and often riotous splendour. Slums’
authors discard Victorian calumnies, but otherwise preserve the classical
definition: overcrowding, poor or informal housing, inadequate access
to safe water and sanitation, and insecurity of tenure.28

This multi-dimensional definition is actually a very conservative gauge
of what qualifies as a slum: many readers will be surprised by the un’s
counter-experiential finding that only 19.6 per cent of urban Mexicans
live in slums. Yet, even with this restrictive definition, Slums estimates
that there were at least 921 million slum-dwellers in 2001: nearly equal
to the population of the world when the young Engels first ventured
onto the mean streets of Manchester. Indeed, neoliberal capitalism has
multiplied Dickens’s notorious slum of Tom-All-Alone in Bleak House by
exponential powers. Residents of slums constitute a staggering 78.2 per
cent of the urban population of the least developed countries and fully a
third of the global urban population.29 Extrapolating from the age struc-
tures of most Third World cities, at least half of the slum population is
under the age of 20.30

The world’s highest percentages of slum-dwellers are in Ethiopia (an
astonishing 99.4 per cent of the urban population), Chad (also 99.4
per cent), Afghanistan (98.5 percent) and Nepal (92 per cent).31 The poor-
est urban populations, however, are probably in Maputo and Kinshasa
where (according to other sources) two-thirds of residents earn less than
the cost of their minimum required daily nutrition.32 In Delhi, planners
complain bitterly about ‘slums within slums’ as squatters take over the
small open spaces of the peripheral resettlement colonies into which
the old urban poor were brutally removed in the mid-1970s.33 In Cairo
and Phnom Penh, recent urban arrivals squat or rent space on rooftops:
creating slum cities in the air.

Slum populations are often deliberately and sometimes massively under-
counted. In the late 1980s, for example, Bangkok had an ‘official’ poverty
rate of only 5 per cent, yet surveys found nearly a quarter of the popula-
tion (1.16 million) living in slums and squatter camps.34 The un, likewise,
recently discovered that it was unintentionally undercounting urban
poverty in Africa by large margins. Slum-dwellers in Angola, for exam-
ple, are probably twice as numerous as it originally believed. Likewise
it underestimated the number of poor urbanites in Liberia: not surpris-
ing, since Monrovia tripled its population in a single year (1989–90) as
panic-stricken country people fled from a brutal civil war.35

There may be more than quarter of a million slums on earth. The five
great metropolises of South Asia (Karachi, Mumbai, Delhi, Kolkata and
Dhaka) alone contain about 15,000 distinct slum communities with a
total population of more than 20 million. An even larger slum popu-
lation crowds the urbanizing littoral of West Africa, while other huge
conurbations of poverty sprawl across Anatolia and the Ethiopian high-
lands; hug the base of the Andes and the Himalayas; explode outward
from the skyscraper cores of Mexico, Jo-burg, Manila and São Paulo;
and, of course, line the banks of the rivers Amazon, Niger, Congo, Nile,
Tigris, Ganges, Irrawaddy and Mekong. The building blocks of this slum
planet, paradoxically, are both utterly interchangeable and spontaneously
unique: including the bustees of Kolkata, the chawls and zopadpattis of
Mumbai, the katchi abadis of Karachi, the kampungs of Jakarta, the iskwa-
ters of Manila, the shammasas of Khartoum, the umjondolos of Durban,
the intra-murios of Rabat, the bidonvilles of Abidjan, the baladis of Cairo,
the gecekondus of Ankara, the conventillos of Quito, the favelas of Brazil,
the villas miseria of Buenos Aires and the colonias populares of Mexico
City. They are the gritty antipodes to the generic fantasy-scapes and resi-
dential themeparks—Philip K. Dick’s bourgeois ‘Offworlds’—in which
the global middle classes increasingly prefer to cloister themselves.

Whereas the classic slum was a decaying inner city, the new slums
are more typically located on the edge of urban spatial explosions. The
horiz ontal growth of cities like Mexico, Lagos or Jakarta, of course, has
been extraordinary, and ‘slum sprawl’ is as much of a problem in the
developing world as suburban sprawl in the rich countries. The devel-
oped area of Lagos, for instance, doubled in a single decade, between

1985 and 1994.36 The Governor of Lagos State told reporters last year
that ‘about two thirds of the state’s total land mass of 3,577 square kilo-
metres could be classified as shanties or slums’.37 Indeed, writes a un
correspondent,

much of the city is a mystery . . . unlit highways run past canyons of
smouldering garbage before giving way to dirt streets weaving through 200
slums, their sewers running with raw waste . . . No one even knows for
sure the size of the population—officially it is 6 million, but most experts
estimate it at 10 million—let alone the number of murders each year [or]
the rate of hiv infection.38

Lagos, moreover, is simply the biggest node in the shanty-town corridor
of 70 million people that stretches from Abidjan to Ibadan: probably the
biggest continuous footprint of urban poverty on earth.39

Slum ecology, of course, revolves around the supply of settlement space.
Winter King, in a recent study published in the Harvard Law Review,
claims that 85 per cent of the urban residents of the developing world
‘occupy property illegally’.40 Indeterminacy of land titles and/or lax state
ownership, in the last instance, are the cracks through which a vast
humanity has poured into the cities. The modes of slum settlement
vary across a huge spectrum, from highly disciplined land invasions
in Mexico City and Lima to intricately organized (but often illegal)
rental markets on the outskirts of Beijing, Karachi and Nairobi. Even
in cities like Karachi, where the urban periphery is formally owned by
the govern ment, ‘vast profits from land speculation . . . continue to
accrue to the private sector at the expense of low-income households’.41
Indeed national and local political machines usually acquiesce in infor-
mal settlement (and illegal private speculation) as long as they can

control the political complexion of the slums and extract a regular flow
of bribes or rents. Without formal land titles or home ownership, slum-
dwellers are forced into quasi-feudal dependencies upon local officials
and party bigshots. Disloyalty can mean eviction or even the razing of
an entire district.

The provision of lifeline infrastructures, meanwhile, lags far behind
the pace of urbanization, and peri-urban slum areas often have no
formal utilities or sanitation provision whatsoever.42 Poor areas of Latin
American cities in general have better utilities than South Asia which,
in turn, usually have minimum urban services, like water and electri-
city, that many African slums lack. As in early Victorian London, the
contamination of water by human and animal waste remains the cause
of the chronic diarrhoeal diseases that kill at least two million urban
babies and small children each year.43 An estimated 57 per cent of urban
Africans lack access to basic sanitation and in cities like Nairobi the poor
must rely on ‘flying toilets’ (defecation into a plastic bag).44 In Mumbai,
meanwhile, the sanitation problem is defined by ratios of one toilet seat
per 500 inhabitants in the poorer districts. Only 11 per cent of poor
neighbourhoods in Manila and 18 per cent in Dhaka have formal means
to dispose of sewage.45 Quite apart from the incidence of the hiv/aids
plague, the un considers that two out of five African slum-dwellers live
in a poverty that is literally ‘life-threatening’.46

The urban poor, meanwhile, are everywhere forced to settle on hazardous
and otherwise unbuildable terrains—over-steep hillslopes, river banks
and floodplains. Likewise they squat in the deadly shadows of refin-
eries, chemical factories, toxic dumps, or in the margins of railroads
and highways. Poverty, as a result, has ‘constructed’ an urban disaster
problem of unprecedented frequency and scope, as typified by chronic
flooding in Manila, Dhaka and Rio, pipeline conflagrations in Mexico
City and Cubatão (Brazil), the Bhopal catastrophe in India, a munitions
plant explosion in Lagos, and deadly mudslides in Caracas, La Paz and

mal workers: selling water, carting nightsoil, recycling trash, delivering propane
and so on.

Tegucigalpa.47 The disenfranchised communities of the urban poor, in
addition, are vulnerable to sudden outbursts of state violence like the
infamous 1990 bulldozing of the Maroko beach slum in Lagos (‘an eye-
sore for the neighbouring community of Victoria Island, a fort ress for
the rich’) or the 1995 demolition in freezing weather of the huge squat-
ter town of Zhejiangcun on the edge of Beijing.48

But slums, however deadly and insecure, have a brilliant future. The
countryside will for a short period still contain the majority of the world’s
poor, but that doubtful title will pass to urban slums by 2035.49 At least
half of the coming Third World urban population explosion will be cred-
ited to the account of informal communities. Two billion slum dwellers
by 2030 or 2040 is a monstrous, almost incomprehensible prospect,
but urban poverty overlaps and exceeds the slums per se. Indeed, Slums
underlines that in some cities the majority of the poor actually live out-
side the slum stricto sensu.50 un ‘Urban Observatory’ researchers warn,
moreover, that by 2020 ‘urban poverty in the world could reach 45 to 50
per cent of the total population living in cities’.51

4. urban poverty’s ‘big bang’

After their mysterious laughter, they quickly changed the topic to
other things. How were people back home surviving sap?

Fidelis Balogun, Adjusted Lives, 1995

The evolution of the new urban poverty has been a non-linear historical
process. The slow accretion of shanty towns to the shell of the city
is punctuated by storms of poverty and sudden explosions of slum-
building. In his collection of stories, Adjusted Lives, the Nigerian writer
Fidelis Balogun describes the coming of the imf-mandated Structural

Adjustment Programme (sap) in the mid-1980s as the equivalent of a
great natural catastrophe, destroying forever the old soul of Lagos and
‘re-enslaving’ urban Nigerians.

The weird logic of this economic programme seemed to be that to restore
life to the dying economy, every juice had first to be sapped out of the under-
privileged majority of the citizens. The middle class rapidly disappeared,
and the garbage heaps of the increasingly rich few became the food table
of the multiplied population of abjectly poor. The brain drain to the oil-rich
Arab countries and to the Western world became a flood.52

Balogun’s complaint about ‘privatizing in full steam and getting more
hungry by the day’, or his enumeration of sap’s malevolent conse-
quences, would be instantly familiar to survivors, not only of the other
30 African saps, but also to hundreds of millions of Asians and Latin
Americans. The 1980s, when the imf and World Bank used the lever-
age of debt to restructure the economies of most of the Third World, are
the years when slums became an implacable future, not just for poor
rural migrants, but also for millions of traditional urbanites, displaced
or immiserated by the violence of ‘adjustment’.

As Slums emphasizes, saps were ‘deliberately anti-urban in nature’ and
designed to reverse any ‘urban bias’ that previously existed in welfare
policies, fiscal structure or government investment.53 Everywhere the
imf—acting as bailiff for the big banks and backed by the Reagan
and Bush administrations—offered poor countries the same poisoned
chalice of devaluation, privatization, removal of import controls and
food subsidies, enforced cost-recovery in health and education, and
ruthless downsizing of the public sector. (An infamous 1985 telegram
from Treasury Secretary George Shultz to overseas usaid officials com-
manded: ‘in most cases, public sector firms should be privatized’.)54

53 The Challenge of Slums, p. 30. ‘Urban bias’ theorists, like Michael Lipton who
invented the term in 1977, argue that agriculture tends to be undercapitalized in
developing countries, and cities relatively ‘overurbanized’, because fiscal and finan-
cial policies favour urban elites and distort investment flows. At the limit, cities
are vampires of the countryside. See Lipton, Why Poor People Stay Poor: A Study of
Urban Bias in World Development, Cambridge 1977.

At the same time, saps devastated rural smallholders by eliminating
subsidies and pushing them out, ‘sink or swim’, into global commodity
markets dominated by First World agribusiness.55

As Ha-Joon Chang points out, saps hypocritically ‘kicked away the ladder’
(i.e., protectionist tariffs and subsidies) that the oecd nations histori-
cally employed in their own climb from agriculture to urban high-value
goods and services.56 Slums makes the same point when it argues that
the ‘main single cause of increases in poverty and inequality during the
1980s and 1990s was the retreat of the state’. In addition to the direct
sap-enforced reductions in public-sector spending and ownership, the
un authors stress the more subtle diminution of state capacity that has
resulted from ‘subsidiarity’: the devolution of powers to lower echelons
of government and, especially, ngos, linked directly to major interna-
tional aid agencies.

The whole, apparently decentralized structure is foreign to the notion of
national representative government that has served the developed world
well, while it is very amenable to the operations of a global hegemony.
The dominant international perspective [i.e., Washington’s] becomes the de
facto paradigm for development, so that the whole world rapidly becomes
unified in the broad direction of what is supported by donors and interna-
tional organizations.57

Urban Africa and Latin America were the hardest hit by the artificial
depression engineered by the imf and the White House. Indeed, in
many countries, the economic impact of saps during the 1980s, in
tandem with protracted drought, rising oil prices, soaring interest rates
and falling commodity prices, was more severe and long-lasting than
the Great Depression.

The balance-sheet of structural adjustment in Africa, reviewed by Carole
Rakodi, includes capital flight, collapse of manufactures, marginal or
negative increase in export incomes, drastic cutbacks in urban public
services, soaring prices and a steep decline in real wages.58 In Kinshasa
(‘an aberration or rather a sign of things to come?’) assainissement wiped
out the civil servant middle class and produced an ‘unbelieveable decline
in real wages’ that, in turn, sponsored a nightmarish rise in crime and
predatory gangs.59 In Dar es Salaam, public service expenditure per
person fell 10 per cent per year during the 1980s: a virtual demolition
of the local state.60 In Khartoum, liberalization and structural adjust-
ment, according to local researchers, manufactured 1.1 million ‘new
poor’: ‘mostly drawn from the salaried groups or public sector employ-
ees’.61 In Abidjan, one of the few tropical African cities with an important
manufacturing sector and modern urban services, submission to the
sap regime punctually led to deindustrialization, the collapse of con-
struction, and a rapid deterioration in public transit and sanitation.62
In Balogun’s Nigeria extreme poverty, increasingly urbanized in Lagos,
Ibadan and other cities, metastatized from 28 per cent in 1980 to 66
per cent in 1996. ‘gnp per capita, at about $260 today,’ the World Bank
reports, ‘is below the level at independence 40 years ago and below the
$370 level attained in 1985.’63

In Latin America, saps (often implemented by military dictatorships)
destabilized rural economies while savaging urban employment and
housing. In 1970, Guevarist ‘foco’ theories of rural insurgency still con-
formed to a continental reality where the poverty of the countryside (75
million poor) overshadowed that of the cities (44 million poor). By the
end of the 1980s, however, the vast majority of the poor (115 million in
1990) were living in urban colonias and villas miseria rather than farms
or villages (80 million).64

Urban inequality, meanwhile, exploded. In Santiago, the Pinochet
dictator ship bulldozed shanty towns and evicted formerly radical squat-
ters: forcing poor families to become allegados, doubled or even tripled-up
in the same rented dwelling. In Buenos Aires, the richest decile’s share
of income increased from 10 times that of the poorest in 1984 to 23
times in 1989.65 In Lima, where the value of the minimum wage fell
by 83 per cent during the imf recession, the percentage of households
living below the poverty threshold increased from 17 percent in 1985
to 44 per cent in 1990.66 In Rio de Janeiro, inequality as measured in
classical Gini coefficients soared from 0.58 in 1981 to 0.67 in 1989.67
Indeed, throughout Latin America, the 1980s deepened the canyons
and elevated the peaks of the world’s most extreme social topography.
(According to a 2003 World Bank report, Gini coefficients are 10 points
higher in Latin America than Asia; 17.5 points higher than the oecd, and
20.4 points higher than Eastern Europe.)68

Throughout the Third World, the economic shocks of the 1980s forced
individuals to regroup around the pooled resources of households and,
especially, the survival skills and desperate ingenuity of women. In
China and the industrializing cities of Southeast Asia, millions of young
women indentured themselves to assembly lines and factory squalor.
In Africa and most of Latin America (Mexico’s northern border cities
excepted), this option did not exist. Instead, deindustrialization and the
decimation of male formal-sector jobs compelled women to improvise
new livelihoods as piece workers, liquor sellers, street vendors, cleaners,
washers, ragpickers, nannies and prostitutes. In Latin America, where
urban women’s labour-force participation had always been lower than
in other continents, the surge of women into tertiary informal activities
during the 1980s was especially dramatic.69 In Africa, where the icons
of the informal sector are women running shebeens or hawking pro-
duce, Christian Rogerson reminds us that most informal women are not

actually self-employed or economically independent, but work for some-
one else.70 (These ubiquitous and vicious networks of micro-exploitation,
of the poor exploiting the very poor, are usually glossed over in accounts
of the informal sector.)

Urban poverty was also massively feminized in the ex-Comecon coun-
tries after capitalist ‘liberation’ in 1989. In the early 1990s extreme
poverty in the former ‘transitional countries’ (as the un calls them)
soared from 14 million to 168 million: a mass pauperization almost
without precedent in history.71 If, on a global balance-sheet, this eco-
nomic catastrophe was partially offset by the much-praised success of
China in raising incomes in its coastal cities, China’s market ‘miracle’
was purchased by ‘an enormous increase in wage inequality among
urban workers . . . during the period 1988 to 1999.’ Women and minori-
ties were especially disadvantaged.72

In theory, of course, the 1990s should have righted the wrongs of
the 1980s and allowed Third World cities to regain lost ground and
bridge the chasms of inequality created by saps. The pain of adjustment
should have been followed by the analgesic of globalization. Indeed
the 1990s, as Slums wryly notes, were the first decade in which global
urban develop ment took place within almost utopian parameters of neo-
classical market freedom.

During the 1990s, trade continued to expand at an almost unprecedented
rate, no-go areas opened up and military expenditures decreased. . . .
All the basic inputs to production became cheaper, as interest rates fell
rapidly along with the price of basic commodities. Capital flows were
increasingly unfettered by national controls and could move rapidly to
the most productive areas. Under what were almost perfect economic
conditions according to the dominant neoliberal economic doctrine, one
might have imagined that the decade would have been one of unrivalled
prosperity and social justice.73

In the event, however, urban poverty continued its relentless accumu-
lation and ‘the gap between poor and rich countries increased, just as
it had done for the previous 20 years and, in most countries, income
inequality increased or, at best, stabilized.’ Global inequality, as meas-
ured by World Bank economists, reached an incredible Gini coefficient
level of 0.67 by the end of the century. This was mathematically equiva-
lent to a situation where the poorest two-thirds of the world receive zero
income; and the top third, everything.74

5. a surplus humanity?

We shove our way about next to City, holding on to it by its
thousand survival cracks . . .

Patrick Chamoiseau, Texaco (1997)

The brutal tectonics of neoliberal globalization since 1978 are analo-
gous to the catastrophic processes that shaped a ‘third world’ in the
first place, during the era of late Victorian imperialism (1870–1900).
In the latter case, the forcible incorporation into the world market of
the great subsistence peasantries of Asia and Africa entailed the famine
deaths of millions and the uprooting of tens of millions more from
trad itional tenures. The end result, in Latin America as well, was rural
‘semi-proletarianization’: the creation of a huge global class of immis-
erated semi-peasants and farm labourers lacking existential security
of subsistence.75 (As a result, the twentieth century became an age,
not of urban revolutions as classical Marxism had imagined, but of
epochal rural uprisings and peasant-based wars of national liberation.)
Structural adjustment, it would appear, has recently worked an equally
fundamental reshaping of human futures. As the authors of Slums con-
clude: ‘instead of being a focus for growth and prosperity, the cities
have become a dumping ground for a surplus population working in
unskilled, unprotected and low-wage informal service industries and
trade.’ ‘The rise of [this] informal sector,’ they declare bluntly, ‘is . . . a
direct result of liberalization.’76

Indeed, the global informal working class (overlapping but non-identical
with the slum population) is almost one billion strong: making it the
fastest growing, and most unprecedented, social class on earth. Since
anthropologist Keith Hart, working in Accra, first broached the concept
of an ‘informal sector’ in 1973, a huge literature (mostly failing to distin-
guish micro-accumulation from sub-subsistence) has wrestled with the
formidable theoretical and empirical problems involved in studying the
survival strategies of the urban poor.77 There is a base consensus, how-
ever, that the 1980s’ crisis inverted the relative structural positions of the
formal and informal sectors: promoting informal survivalism as the new
primary mode of livelihood in a majority of Third World cities.

Alejandro Portes and Kelly Hoffman have recently evaluated the overall
impact of saps and liberalization upon Latin American urban class
structures since the 1970s. Congruent with un conclusions, they find
that both state employees and the formal proletariat have declined
in every country of the region since the 1970s. In contrast, the
informal sector of the economy, along with general social inequality, has
drama tically expanded. Unlike some researchers, they make a crucial
distinction between an informal petty bourgeoisie (‘the sum of owners
of microenterprises, employing less than five workers, plus own-account
professionals and technicians’) and the informal proletariat (‘the sum
of own-account workers minus professionals and technicians, domestic
servants, and paid and unpaid workers in microenterprises’). They dem-
onstrate that this former stratum, the ‘microentrepreneurs’ so beloved in
North American business schools, are often displaced public-sector pro-
fessionals or laid-off skilled workers. Since the 1980s, they have grown
from about 5 to 10 per cent of the economically active urban population:
a trend reflecting ‘the forced entrepreneurialism foisted on former sala-
ried employees by the decline of formal sector employment.’78

Overall, according to Slums, informal workers are about two-fifths of
the economically active population of the developing world.79 According
to researchers at the Inter-American Development Bank, the informal

economy currently employs 57 per cent of the Latin American work-
force and supplies four out of five new ‘jobs’.80 Other sources claim that
more than half of urban Indonesians and 65 per cent of residents of
Dhaka subsist in the informal sector.81 Slums likewise cites research find-
ing that informal economic activity accounts for 33 to 40 per cent of
urban employment in Asia, 60 to 75 per cent in Central America and
60 per cent in Africa.82 Indeed, in sub-Saharan cities ‘formal job’ crea-
tion has virtually ceased to exist. An ilo study of Zimbabwe’s urban
labour markets under ‘stagflationary’ structural adjustment in the early
1990s found that the formal sector was creating only 10,000 jobs per
year in face of an urban workforce increasing by more than 300,000
per annum.83 Slums similarly estimates that fully 90 per cent of urban
Africa’s new jobs over the next decade will somehow come from the
informal sector.84

The pundits of bootstrap capitalism, like the irrepressible Hernando
de Soto, may see this enormous population of marginalized labourers,
redundant civil servants and ex-peasants as actually a frenzied beehive
of ambitious entrepreneurs yearning for formal property rights and
unregulated competitive space, but it makes more obvious sense to con-
sider most informal workers as the ‘active’ unemployed, who have no
choice but to subsist by some means or starve.85 The world’s estimated
100 million street kids are not likely—apologies to Señor de Soto—to
start issuing ipos or selling chewing-gum futures.86 Nor will most of

85 Orlandina de Oliveira and Bryan Roberts rightly emphasize that the bottom
strata of the urban labour-force should be identified ‘not simply by occupational
titles or whether the job was formal or informal, but by the household strategy
for obtaining an income’. The mass of the urban poor can only exist by ‘income
pooling, sharing housing, food and other resources’ either with kin or landsmen.

China’s 70 million ‘floating workers’, living furtively on the urban
periphery, eventually capitalize themselves as small subcontractors or
integrate into the formal urban working class. And the informal working
class—everywhere subject to micro- and macro-exploitation—is almost
universally deprived of protection by labour laws and standards.

Moreover, as Alain Dubresson argues in the case of Abidjan, ‘the dyna-
mism of crafts and small-scale trade depends largely on demand from
the wage sector’. He warns against the ‘illusion’ cultivated by the ilo
and World Bank that ‘the informal sector can efficiently replace the
formal sector and promote an accumulation process sufficient for a city
with more than 2.5 million inhabitants’.87 His warning is echoed by
Christian Rogerson who, distinguishing (à la Portes and Hoffman) ‘sur-
vivalist’ from ‘growth’ micro-enterprises, writes of the former: ‘generally
speaking, the incomes generated from these enterprises, the majority
of which tend to be run by women, usually fall short of even a mini-
mum living standard and involve little capital investment, virtually no
skills training, and only constrained opportunities for expansion into a
viable business’. With even formal-sector urban wages in Africa so low
that economists can’t figure out how workers survive (the so-called ‘wage
puzzle’), the informal tertiary sector has become an arena of extreme
Darwinian competition amongst the poor. Rogerson cites the examples
of Zimbabwe and South Africa where female-controlled informal niches
like shebeens and spazas are now drastically overcrowded and plagued
by collapsing profitability.88

The real macroeconomic trend of informal labour, in other words, is the
reproduction of absolute poverty. But if the informal proletariat is not
the pettiest of petty bourgeoisies, neither is it a ‘labour reserve army’
or a ‘lumpen proletariat’ in any obsolete nineteenth-century sense. Part
of it, to be sure, is a stealth workforce for the formal economy and
numerous studies have exposed how the subcontracting networks of
WalMart and other mega-companies extend deep into the misery of
the colonias and chawls. But at the end of the day, a majority of urban
slum-dwellers are truly and radically homeless in the contemporary
international economy.

Slums, of course, originate in the global countryside where, as Deborah
Bryceson reminds us, unequal competition with large-scale agro-industry
is tearing traditional rural society ‘apart at the seams’.89 As rural areas
lose their ‘storage capacity’, slums take their place, and urban ‘involu-
tion’ replaces rural involution as a sink for surplus labour which can only
keep pace with subsistence by ever more heroic feats of self-exploitation
and the further competitive subdivision of already densely filled sur-
vival niches.90 ‘Modernization’, ‘Development’ and, now, the unfettered
‘Market’ have had their day. The labour-power of a billion people has
been expelled from the world system, and who can imagine any plausi-
ble scenario, under neoliberal auspices, that would reintegrate them as
productive workers or mass consumers?

6. marx and the holy ghost

[The Lord says:] The time will come when the poor man will say that he has
nothing to eat and work will be shut down . . . That is going to cause the
poor man to go to these places and break in to get food. This will cause the
rich man to come out with his gun to make war with the labouring man. . .
. blood will be in the streets like an outpouring rain from heaven.

A prophecy from the 1906 ‘Azusa Street Awakening’

The late capitalist triage of humanity, then, has already taken place. The
global growth of a vast informal proletariat, moreover, is a wholly origi-
nal structural development unforeseen by either classical Marxism or
modernization pundits. Slums indeed challenges social theory to grasp
the novelty of a true global residuum lacking the strategic economic
power of socialized labor, but massively concentrated in a shanty-town
world encircling the fortified enclaves of the urban rich.

Tendencies toward urban involution, of course, existed during the nine-
teenth century. The European industrial revolutions were incapable of

89 Bryceson, ‘Disappearing Peasantries’, pp. 307–8.
90 In Clifford Geertz’s original, inimitable definition, ‘involution’ is ‘an over driving
of an established form in such a way that it becomes rigid through an inward
over-elaboration of detail’. (Agricultural involution: Social development and economic
change in two Indonesian towns, Chicago 1963, p. 82.) More prosaically, ‘involution’,
agricultural or urban, can be described as spiralling labour self-exploitation (other
factors fixed) which continues, despite rapidly diminishing returns, as long as any
return or increment is produced.

absorbing the entire supply of displaced rural labour, especially after
conti nental agriculture was exposed to the devastating competition of the
North American prairies from the 1870s. But mass immigration to the
settler societies of the Americas and Oceania, as well as Siberia, provided
a dynamic safety-valve that prevented the rise of mega-Dublins as well
as the spread of the kind of underclass anarchism that had taken root in
the most immiserated parts of Southern Europe. Today surplus labour,
by contrast, faces unprecedented barriers—a literal ‘great wall’ of high-
tech border enforcement—blocking large-scale migration to the rich
countries. Likewise, controversial population resettlement programmes
in ‘frontier’ regions like Amazonia, Tibet, Kalimantan and Irian Jaya
produce environmental devastation and ethnic conflict without substan-
tially reducing urban poverty in Brazil, China and Indonesia.

Thus only the slum remains as a fully franchised solution to the problem
of warehousing the twenty-first century’s surplus humanity. But aren’t
the great slums, as a terrified Victorian bourgeoisie once imagined,
volcanoes waiting to erupt? Or does ruthless Darwinian competition,
as increasing numbers of poor people compete for the same informal
scraps, ensure self-consuming communal violence as yet the highest
form of urban involution? To what extent does an informal proletariat
possess that most potent of Marxist talismans: ‘historical agency’?
Can disincorporated labour be reincorporated in a global emancipatory
project? Or is the sociology of protest in the immiserated megacity a
regression to the pre-industrial urban mob, episodically explosive during
consumption crises, but otherwise easily managed by clientelism, popu-
list spectacle and appeals to ethnic unity? Or is some new, unexpected
historical subject, à la Hardt and Negri, slouching toward the supercity?

In truth, the current literature on poverty and urban protest offers few
answers to such large-scale questions. Some researchers, for example,
would question whether the ethnically diverse slum poor or econ-
omically heterogeneous informal workers even constitute a meaningful
‘class in itself’, much less a potentially activist ‘class for itself’. Surely, the
informal proletariat bears ‘radical chains’ in the Marxist sense of having
little or no vested interest in the preservation of the existing mode of
production. But because uprooted rural migrants and informal workers
have been largely dispossessed of fungible labour-power, or reduced to
domestic service in the houses of the rich, they have little access to
the culture of collective labour or large-scale class struggle. Their social

davis: Planet of Slums 29

stage, necessarily, must be the slum street or marketplace, not the fac-
tory or international assembly line.

Struggles of informal workers, as John Walton emphasizes in a recent
review of research on social movements in poor cities, have tended,
above all, to be episodic and discontinuous. They are also usually focused
on immediate consumption issues: land invasions in search of afford-
able housing and riots against rising food or utility prices. In the past,
at least, ‘urban problems in developing societies have been more typi-
cally mediated by patron–client relations than by popular activism.’91
Since the debt crisis of the 1980s, neopopulist leaders in Latin America
have had dramatic success in exploiting the desperate desire of the
urban poor for more stable, predictable structures of daily life. Although
Walton doesn’t make the point explicitly, the urban informal sector has
been ideologically promiscuous in its endorsement of populist saviours:
in Peru rallying to Fujimori, but in Venezuela embracing Chávez.92 In
Africa and South Asia, on the other hand, urban clientelism too often
equates with the dominance of ethno-religious bigots and their night-
mare ambitions of ethnic cleansing. Notorious examples include the
anti-Muslim militias of the Oodua People’s Congress in Lagos and the
semi-fascist Shiv Sena movement in Bombay.93

Will such ‘eighteenth-century’ sociologies of protest persist into the middle
twenty-first century? The past is probably a poor guide to the future.
History is not uniformitarian. The new urban world is evolving with
extraordinary speed and often in unpredictable directions. Everywhere
the continuous accumulation of poverty undermines existential security
and poses even more extraordinary challenges to the economic ingenu-
ity of the poor. Perhaps there is a tipping point at which the pollution,
congestion, greed and violence of everyday urban life finally overwhelm
the ad hoc civilities and survival networks of the slum. Certainly in the old

rural world there were thresholds, often calibrated by famine, that passed
directly to social eruption. But no one yet knows the social temperature at
which the new cities of poverty spontaneously combust.

Indeed, for the moment at least, Marx has yielded the historical stage to
Mohammed and the Holy Ghost. If God died in the cities of the indus-
trial revolution, he has risen again in the postindustrial cities of the
developing world. The contrast between the cultures of urban poverty in
the two eras is extraordinary. As Hugh McLeod has shown in his magis-
terial study of Victorian working-class religion, Marx and Engels were
largely accurate in their belief that urbanization was secularizing the
working class. Although Glasgow and New York were partial exceptions,
‘the line of interpretation that associates working-class detachment from
the church with growing class consciousness is in a sense incontestable’.
If small churches and dissenting sects thrived in the slums, the great
current was active or passive disbelief. Already by the 1880s, Berlin was
scandalizing foreigners as ‘the most irreligious city in the world’ and in
London, median adult church attendance in the proletarian East End and
Docklands by 1902 was barely 12 per cent (and that mostly Catholic).94
In Barcelona, of course, an anarchist working class sacked the churches
during the Semana Trágica, while in the slums of St. Petersburg, Buenos
Aires and even Tokyo, militant workers avidly embraced the new faiths
of Darwin, Kropotkin and Marx.

Today, on the other hand, populist Islam and Pentecostal Christianity
(and in Bombay, the cult of Shivaji) occupy a social space analogous to
that of early twentieth-century socialism and anarchism. In Morocco, for
instance, where half a million rural emigrants are absorbed into the teem-
ing cities every year, and where half the population is under 25, Islamicist
movements like ‘Justice and Welfare’, founded by Sheik Abdessalam
Yassin, have become the real governments of the slums: organizing night
schools, providing legal aid to victims of state abuse, buying medicine
for the sick, subsidizing pilgrimages and paying for funerals. As Prime
Minister Abderrahmane Youssoufi, the Socialist leader who was once
exiled by the monarchy, recently admitted to Ignacio Ramonet, ‘We [the
Left] have become embourgeoisified. We have cut ourselves off from the
people. We need to reconquer the popular quarters. The Islamicists have

York, 1870–1914, New York 1996, pp. xxv, 6, 32.

davis: Planet of Slums 31

seduced our natural electorate. They promise them heaven on earth.’ An
Islamicist leader, on the other hand, told Ramonet: ‘confronted with the
neglect of the state, and faced with the brutality of daily life, people dis-
cover, thanks to us, solidarity, self-help, fraternity. They understand that
Islam is humanism.’95

The counterpart of populist Islam in the slums of Latin America and
much of sub-Saharan Africa is Pentecostalism. Christianity, of course, is
now, in its majority, a non-Western religion (two-thirds of its adherents
live outside Europe and North America), and Pentecostalism is its most
dynamic missionary in cities of poverty. Indeed the historical specifi-
city of Pentecostalism is that it is the first major world religion to have
grown up almost entirely in the soil of the modern urban slum. With
roots in early ecstatic Methodism and African-American spirituality,
Pentecostalism ‘awoke’ when the Holy Ghost gave the gift of tongues to
participants in an interracial prayer marathon in a poor neighbourhood
of Los Angeles (Azusa Street) in 1906. Unified around spirit baptism,
miracle healing, charismata and a premillennial belief in a coming
world war of capital and labour, early American Pentecostalism—as
religious historians have repeatedly noted—originated as a ‘prophetic
democracy’ whose rural and urban constituencies overlapped, respec-
tively, with those of Populism and the iww.96 Indeed, like Wobbly
organizers, its early missionaries to Latin America and Africa ‘lived
often in extreme poverty, going out with little or no money, seldom
knowing where they would spend the night, or how they would get
their next meal.’97 They also yielded nothing to the iww in their
vehement denunciations of the injustices of industrial capitalism and
its inevitable destruction.

Symptomatically, the first Brazilian congregation, in an anarchist
working-class district of São Paulo, was founded by an Italian artisan

95 Ignacio Ramonet, ‘Le Maroc indécis’, Le Monde diplomatique, July 2000, pp.
12–13. Another former leftist told Ramonet: ‘Nearly 65 per cent of the population
lives under the poverty line. The people of the bidonvilles are entirely cut off from
the elites. They see the elites the way they used to see the French.’
96 In his controversial sociological interpretation of Pentecostalism, Robert Mapes
Anderson claimed that ‘its unconscious intent’, like other millenarian movements,
was actually ‘revolutionary’. (Vision of the Disinherited: The Making of American
Pentecostalism, Oxford 1979, p. 222.)

immigrant who had exchanged Malatesta for the Spirit in Chicago.98
In South Africa and Rhodesia, Pentecostalism established its early foot-
holds in the mining compounds and shanty towns; where, according
to Jean Comaroff, ‘it seemed to accord with indigenous notions of
pragmatic spirit forces and to redress the depersonalization and power-
lessness of the urban labour experience.’99 Conceding a larger role to
women than other Christian churches and immensely supportive of
abstinence and frugality, Pentecostalism—as R. Andrew Chesnut discov-
ered in the baixadas of Belém—has always had a particular attraction to
‘the most immiserated stratum of the impoverished classes’: abandoned
wives, widows and single mothers.100 Since 1970, and largely because of
its appeal to slum women and its reputation for being colour-blind, it
has been growing into what is arguably the largest self-organized move-
ment of urban poor people on the planet.101

Although recent claims of ‘over 533 million Pentecostal/charismatics
in the world in 2002’ are probably hyperbole, there may well be half
that number. It is generally agreed that 10 per cent of Latin America
is Pentecostal (about 40 million people) and that the movement has
been the single most important cultural response to explosive and trau-
matic urbanization.102 As Pentecostalism has globalized, of course, it has

differentiated into distinct currents and sociologies. But if in Liberia,
Mozambique and Guatemala, American-sponsored churches have been
vectors of dictatorship and repression, and if some us congregations are
now gentrified into the suburban mainstream of fundamentalism, the
missionary tide of Pentecostalism in the Third World remains closer to
the original millenarian spirit of Azusa Street.103 Above all, as Chesnut
found in Brazil, ‘Pentecostalism . . . remains a religion of the informal
periphery’ (and in Belém, in particular, ‘the poorest of the poor’). In
Peru, where Pentecostalism is growing almost exponentially in the vast
barriadas of Lima, Jefrey Gamarra contends that the growth of the sects
and of the informal economy ‘are a consequence of and a response to
each other’.104 Paul Freston adds that it ‘is the first autonomous mass
religion in Latin America . . . Leaders may not be democratic, but they
come from the same social class’.105

In contrast to populist Islam, which emphasizes civilizational continu-
ity and the trans-class solidarity of faith, Pentecostalism, in the tradition
of its African-American origins, retains a fundamentally exilic identity.
Although, like Islam in the slums, it efficiently correlates itself to
the survival needs of the informal working class (organizing self-help
networks for poor women; offering faith healing as para-medicine; pro-
viding recovery from alcoholism and addiction; insulating children from
the temptations of the street; and so on), its ultimate premise is that
the urban world is corrupt, injust and unreformable. Whether, as Jean

of which are now Pentecostal), this religion of ‘the marginalized in the

shantytowns of neocolonial modernity’ is actually a ‘more radical’ resist-
ance than ‘participation in formal politics or labour unions’, remains to
be seen.106 But, with the Left still largely missing from the slum, the
eschatology of Pentecostalism admirably refuses the inhuman destiny of
the Third World city that Slums warns about. It also sanctifies those who,
in every structural and existential sense, truly live in exile.

The earth reaches a momentous
milestone: by next year, for the first time
in history, more than half its population
will be living in cities. Those 3.3 billion
people are expected to grow to 5 billion
by 2030 — this unique map of the world
shows where those people live now

At the beginning of the 20th
century, the world’s urban
population was only 220
million, mainly in the west

By 2030, the towns and
cities of the developing
world will make up 80%
of urban humanity

What is a Developing Country?

Since 1971, the United Nations has recognized least developed countries
(LDCs) as a category. LDCs are defined as low-income countries suffering
from structural impediments to sustainable development.

https://unctad.org/topic/least-developed-countries/map

What is a Developing Country?

The list of LDCs is reviewed every three years by the United Nations
Economic and Social Council, in the light of recommendations by the
Committee for Development Policy (CDP).

The following three criteria are used by the CDP to determine LDC status:

• Per capita income (gross national income per capita)

• Human assets (indicators of nutrition, health, school enrolment and literacy)

• Economic vulnerability (indicators of natural and trade-related shocks, physical
and economic exposure to shocks, and smallness and remoteness).

https://unctad.org/en/pages/aldc/Least%20Developed%20Countries/UN-list-of-Least-Developed-Countries.aspx

The Paradox of Mega Cities

• Great Wealth

• Pulls in global resources

• Centralized resources

• Refuge from severe weather

events

• Great Poverty

• Encroaches on natural resources

• Inequitable distribution of resources

• Intensify severe weather events

(example: urban heat island)

Informal Cities

Informal City/Slum Housing
UN-HABITAT defines a slum household as a group of individuals living under the same roof
in an urban area who lack one or more of the following:

1. Durable housing of a permanent nature that protects against extreme climate
conditions.

2. Sufficient living space which means not more than three people sharing the same
room.

3. Easy access to safe water in sufficient amounts at an affordable price.

4. Access to adequate sanitation in the form of a private or public toilet shared by a
reasonable number of people.

5. Security of tenure that prevents forced evictions.

• Not just about birth rates
• Economic drivers
• Environmental divers
• Urban lifestyles

We can learn from these informal cities and settlements?

Sustainability Defined

“Development that meets the needs of the present without compromising

the ability of future generations to meet their own needs.” (Sorensen et al)

The Idea of sustainable development will be particularly effective if “it acts

as a lightning rod to focus conflicting economic, environmental and social

interests. The more it stirs up conflict and sharpens the debate, the more

effective the idea will be in the long run.” (Sorensen et al)
