Key points
- Davis: vulnerability is built over years through segregation, investment, property and decisions about who gets protected.
- Malibu burns and is rebuilt with public money while the flatlands flood: disaster damage follows the lines of class and race.
- The famines of the late nineteenth century show that nature supplies the trigger and power supplies the catastrophe.
Risk is not natural; it is a construct of power and inequality, and Mike Davis (1946-2022), the historian and urban theorist of Los Angeles, made that claim the centre of an environmental Marxism developed from City of Quartz (1990) through Ecology of Fear (1998) to Planet of Slums (2006). Two neighbourhoods face the same threat but do not reach the disaster in the same condition: one has resources, protection and capacity to react, the other accumulates precarity and exposure long before the critical moment. Davis's uncomfortable question is when an urban disaster really begins, and his answer is that vulnerability is not created suddenly by the catastrophe but built over years through segregation, investment, property and decisions about who gets protected.
The unequal production of territory: speculation, segregation, fortification
The mechanism begins with the unequal production of territory. Investment transforms some spaces while others accumulate precarious conditions; real estate speculation turns certain zones into opportunities for valorisation; segregation separates populations and resources within the same city; and then privatisation and militarisation reorganise access, security and control. These pieces form a geography in which some groups can protect their positions while others remain more exposed, and capitalism, Davis argues, takes an active part in that production: land, infrastructure and protective capacity are organised unequally first, and when a threat appears, those differences decide who can face it.
Ecology of Fear: Malibu burns, the flatlands flood
Los Angeles is his laboratory. In Ecology of Fear, Davis showed that the city's disasters, fires, floods, earthquakes, are read as acts of nature while their damage follows the lines of class and race: the wealthy canyons of Malibu burn and are rebuilt with public money and insurance, in a chapter provocatively titled The Case for Letting Malibu Burn, while the poor neighbourhoods of the flatlands flood, breathe the worst air and receive the least protection. City of Quartz had already described the fortress city, with its gated enclaves, privatised public space and militarised policing, as the spatial form of that inequality, and the riots of 1992 confirmed that the fear the city organised itself around was a political product.
From imperial famines to the planet of slums: nature triggers, power decides
Late Victorian Holocausts (2001) carried the argument to global history. Davis showed that the famines of the late nineteenth century in India, China and Brazil, which killed tens of millions, were not caused by the droughts of El Niño alone but by the imperial policies that turned drought into famine, exporting grain, dismantling traditional reserves and imposing markets; nature supplied the trigger, power supplied the catastrophe. Planet of Slums extended the reading to the present: a billion people living in informal settlements on hillsides, floodplains and toxic sites are the population most exposed to climate disasters not by chance but because those were the only places left to them.
Vulnerability studies, Katrina, criticism and the lesson
Davis's framework converses with the vulnerability studies of Ben Wisner and Piers Blaikie, who formulated in At Risk (1994) that disaster equals hazard multiplied by vulnerability, and with the environmental justice movement; it has been confirmed by Katrina in New Orleans, by the heatwaves that kill in the poorest neighbourhoods and by every flood in the Global South. Critics reproached him for a catastrophist tone and a determinism that leaves little room for the agency of communities; Davis replied that naming the structures that produce vulnerability is the condition for those communities to change them.
The lesson of Mike Davis is that a disaster begins long before the emergency, in the decisions that decide who lives on the floodplain, who has insurance, whose neighbourhood gets the levee and whose gets the incinerator. Reading risk as a construct of power turns disaster policy into urban policy: distributing protection, housing and infrastructure fairly before the threat arrives is the only prevention that works, and celebrating resilience afterwards without asking who built the risk is, in his reading, the way the city keeps producing the next catastrophe.
Frequently asked questions
What does Mike Davis mean by saying risk is not natural?
That the damage of fires, floods, droughts or earthquakes follows the lines of class and race because vulnerability is produced beforehand by speculation, segregation, privatisation and unequal investment in protection, so that the disaster begins long before the emergency, in the decisions about who lives where and who is protected.
How does Ecology of Fear explain the disasters of Los Angeles?
By showing that the city's fires, floods and earthquakes are read as acts of nature while their damage is unequal: the wealthy canyons of Malibu burn and are rebuilt with public money and insurance, while the poor flatlands flood, breathe the worst air and receive the least protection, in a fortress city organised around fear.
