Robert Muggah: How to protect fast-growing cities from failing

Filmed:

Worldwide, violence is on the decline, but in the crowded cities of the global south — cities like Aleppo, Bamako and Caracas — violence is actually accelerating, fueled by the drug trade, mass unemployment and civil unrest. Security researcher Robert Muggah turns our attention toward these “fragile cities,” super-fast-growing places where infrastructure is weak and government often ineffective. He shows us the four big risks we face, and offers a way to change course.

We can cut violent deaths
around the world
00:12
by 50 percent in the next three decades.
00:17
All we have to do
is drop killing by 2.3 percent a year,
00:22
and we'll hit that target.
00:27
You don't believe me?
00:29
Well, the leading epidemiologists
and criminologists around the world
00:31
seem to think we can, and so do I,
00:34
but only if we focus on our cities,
especially the most fragile ones.
00:37
You see, I've been thinking
about this a lot.
00:42
For the last 20 years, I've been working
00:46
in countries and cities
ripped apart by conflict,
00:48
violence, terrorism, or some
insidious combination of all.
00:51
I've tracked gun smugglers
from Russia to Somalia,
00:55
I've worked with warlords
in Afghanistan and the Congo,
00:59
I've counted cadavers in Colombia, in
Haiti, in Sri Lanka, in Papua New Guinea.
01:02
You don't need to be
on the front line, though,
01:08
to get a sense that our planet
is spinning out of control, right?
01:10
There's this feeling that international
instability is the new normal.
01:13
But I want you to take a closer look,
01:18
and I think you'll see that
the geography of violence is changing,
01:20
because it's not so much our nation states
that are gripped by conflict and crime
01:23
as our cities: Aleppo, Bamako, Caracas,
Erbil, Mosul, Tripoli, Salvador.
01:27
Violence is migrating to the metropole.
01:35
And maybe this is to be expected, right?
01:38
After all, most people today,
they live in cities, not the countryside.
01:40
Just 600 cities, including 30 megacities,
account for two thirds of global GDP.
01:44
But when it comes to cities,
01:50
the conversation is
dominated by the North,
01:52
that is, North America, Western Europe,
Australia and Japan,
01:55
where violence is
actually at historic lows.
01:58
As a result, city enthusiasts, they talk
about the triumph of the city,
02:01
of the creative classes, and the mayors
that will rule the world.
02:06
Now, I hope that mayors
do one day rule the world,
02:10
but, you know, the fact is,
02:13
we don't hear any conversation, really,
about what is happening in the South.
02:15
And by South, I mean
Latin America, Africa, Asia,
02:20
where violence in some
cases is accelerating,
02:24
where infrastructure is overstretched,
02:27
and where governance is sometimes
an aspiration and not a reality.
02:29
Now, some diplomats
and development experts and specialists,
02:34
they talk about 40 to 50 fragile states
02:38
that will shape security
in the 21st century.
02:41
I think it's fragile cities which will
define the future of order and disorder.
02:44
That's because warfare
and humanitarian action
02:50
are going to be
concentrated in our cities,
02:53
and the fight for development,
02:55
whether you define that
as eradicating poverty,
02:57
universal healthcare,
beating back climate change,
02:59
will be won or lost in the shantytowns,
slums and favelas of our cities.
03:02
I want to talk to you about four megarisks
03:07
that I think will define
fragility in our time,
03:10
and if we can get to grips with these,
03:13
I think we can do something
with that lethal violence problem.
03:16
So let me start with some good news.
03:18
Fact is, we're living in the most
peaceful moment in human history.
03:21
Steven Pinker and others have shown how
the intensity and frequency of conflict
03:26
is actually at an all-time low.
03:30
Now, Gaza, Syria, Sudan, Ukraine,
03:33
as ghastly as these conflicts are,
and they are horrific,
03:37
they represent a relatively
small blip upwards
03:41
in a 50-year-long secular decline.
03:43
What's more, we're seeing
a dramatic reduction in homicide.
03:46
Manuel Eisner and others have shown
03:51
that for centuries, we've seen
this incredible drop in murder,
03:53
especially in the West.
03:57
Most Northern cities today are 100 times
safer than they were just 100 years ago.
03:59
These two facts -- the decline in armed
conflict and the decline in murder --
04:04
are amongst the most extraordinary,
04:08
if unheralded, accomplishments
of human history,
04:09
and we should be really excited, right?
04:12
Well, yeah, we should.
04:15
There's just one problem:
These two scourges are still with us.
04:17
You see, 525,000 people --
men, women, boys and girls --
04:22
die violently every single year.
04:28
Research I've been doing
with Keith Krause and others
04:31
has shown that between 50,000 and 60,000
people are dying in war zones violently.
04:33
The rest, almost 500,000 people,
are dying outside of conflict zones.
04:39
In other words, 10 times more people
are dying outside of war than inside war.
04:44
What's more, violence is moving south,
04:50
to Latin America and the Caribbean,
04:53
to parts of Central and Southern Africa,
04:56
and to bits of the Middle East
and Central Asia.
04:58
Forty of the 50 most dangerous
cities in the world
05:01
are right here in Latin America,
05:04
13 in Brazil,
05:05
and the most dangerous of all, it's
San Pedro Sula, Honduras' second city,
05:07
with a staggering homicide rate
of 187 murders per 100,000 people.
05:12
That's 23 times the global average.
05:17
Now, if violence is
re-concentrating geographically,
05:20
it's also being reconfigured
to the world's new topography,
05:23
because when it comes to cities,
the world ain't flat,
05:26
like Thomas Friedman likes to say.
05:28
It's spiky.
05:31
The dominance of the city
as the primary mode of urban living
05:32
is one of the most extraordinary
demographic reversals in history,
05:36
and it all happened so fast.
05:40
You all know the figures, right?
05:43
There's 7.3 billion people
in the world today;
05:45
there will be 9.6 billion by 2050.
05:47
But consider this one fact:
05:49
In the 1800s, one in 30
people lived in cities,
05:51
today it's one in two,
05:55
and tomorrow virtually everyone
is going to be there.
05:57
And this expansion in urbanization
is going to be neither even nor equitable.
06:00
The vast majority, 90 percent,
06:04
will be happening in the South,
in cities of the South.
06:06
So urban geographers and demographers,
06:10
they tell us that it's not necessarily
the size or even the density of cities
06:13
that predicts violence, no.
06:18
Tokyo, with 35 million people,
06:20
is one of the largest, and some might say
safest, urban metropolises in the world.
06:22
No, it's the speed of
urbanization that matters.
06:27
I call this turbo-urbanization, and it's
one of the key drivers of fragility.
06:30
When you think about the incredible
expansion of these cities,
06:36
and you think about turbo-urbanization,
think about Karachi.
06:41
Karachi was about 500,000 people in 1947,
a hustling, bustling city.
06:45
Today, it's 21 million people,
06:51
and apart from accounting
for three quarters of Pakistan's GDP,
06:54
it's also one of the most violent
cities in South Asia.
06:58
Dhaka, Lagos, Kinshasa,
07:01
these cities are now 40 times larger
than they were in the 1950s.
07:04
Now take a look at New York.
07:09
The Big Apple, it took 150 years
to get to eight million people.
07:11
São Paulo, Mexico City, took 15
to reach that same interval.
07:16
Now, what do these medium,
large, mega-, and hypercities look like?
07:21
What is their profile?
07:25
Well, for one thing, they're young.
07:27
What we're seeing in many of them
is the rise of the youth bulge.
07:29
Now, this is actually a good news story.
07:32
It's a function of reductions
in child mortality rates.
07:34
But the youth bulge is something
we've got to watch.
07:37
What it basically means
07:39
is the proportion of young people
living in our fragile cities
07:41
is much larger than those living
in our healthier and wealthier ones.
07:44
In some fragile cities,
07:47
75 percent of the population
is under the age of 30.
07:49
Think about that:
Three in four people are under 30.
07:52
It's like Palo Alto on steroids.
07:57
Now, if you look at Mogadishu for example,
08:00
in Mogadishu the mean age is 16 years old.
08:03
Ditto for Dhaka, Dili and Kabul.
08:07
And Tokyo? It's 46.
08:10
Same for most Western European cities.
08:12
Now, it's not just youth
that necessarily predicts violence.
08:16
That's one factor among many,
08:19
but youthfulness combined
with unemployment, lack of education,
08:21
and -- this is the kicker --
being male, is a deadly proposition.
08:24
They're statistically correlated,
all those risk factors, with youth,
08:28
and they tend to relate
to increases in violence.
08:32
Now, for those of you who are
parents of teenage sons,
08:36
you know what I'm talking about, right?
08:39
Just imagine your boy
without any structure
08:41
with those unruly friends of his,
out there cavorting about.
08:44
Now, take away the parents,
08:47
take away the education,
limit the education possibilities,
08:50
sprinkle in a little bit of drugs,
alcohol and guns,
08:54
and sit back and watch the fireworks.
08:57
The implications are disconcerting.
09:00
Right here in Brazil,
the life expectancy is 73.6 years.
09:03
If you live in Rio, I'm sorry,
shave off two right there.
09:06
But if you're young, you're uneducated,
09:10
you lack employment,
you're black, and you're male,
09:12
your life expectancy drops
to less than 60 years old.
09:15
There's a reason why youthfulness
and violence are the number one killers
09:18
in this country.
09:23
Okay, so it's not all doom
and gloom in our cities.
09:25
After all, cities are hubs of innovation,
09:28
dynamism, prosperity,
excitement, connectivity.
09:31
They're where the smart people gather.
09:34
And those young people I just mentioned,
09:36
they're more digitally savvy
and tech-aware than ever before.
09:38
And this explosion, the Internet,
and mobile technology,
09:42
means that the digital divide
separating the North and the South
09:46
between countries
and within them, is shrinking.
09:49
But as we've heard so many times,
09:53
these new technologies
are dual-edged, right?
09:54
Take the case of law enforcement.
09:57
Police around the world are starting
to use remote sensing and big data
09:59
to anticipate crime.
10:03
Some cops are able to predict
criminal violence before it even happens.
10:04
The future crime scenario,
it's here today,
10:09
and we've got to be careful.
10:12
We have to manage the issues
of the public safety
10:14
against rights to individual privacy.
10:16
But it's not just the cops
who are innovating.
10:18
We've heard extraordinary activities
of civil society groups
10:21
who are engaging in local
and global collective action,
10:23
and this is leading to digital protest
and real revolution.
10:27
But most worrying
of all are criminal gangs
10:31
who are going online
and starting to colonize cyberspace.
10:35
In Ciudad Juárez in Mexico,
where I've been working,
10:38
groups like the Zetas
and the Sinaloa cartel
10:41
are hijacking social media.
10:43
They're using it to recruit,
to sell their products,
10:45
to coerce, to intimidate and to kill.
10:47
Violence is going virtual.
10:49
So this is just a partial sketch
10:53
of a fast-moving and dynamic
and complex situation.
10:55
I mean, there are many other megarisks
10:57
that are going to define
fragility in our time,
10:59
not least income inequality,
11:02
poverty, climate change, impunity.
11:04
But we're facing a stark dilemma
11:07
where some cities are going to thrive
and drive global growth
11:10
and others are going to stumble
and pull it backwards.
11:14
If we're going to change course,
we need to start a conversation.
11:17
We can't only focus
on those cities that work,
11:20
the Singapores, the Kuala Lumpurs,
11:23
the Dubais, the Shanghais.
11:25
We've got to bring those fragile cities
into the conversation.
11:27
One way to do this might be
to start twinning
11:32
our fragile cities with our healthier
and wealthier ones,
11:34
kickstarting a process of learning
and collaboration
11:37
and sharing of practices,
of what works and what doesn't.
11:39
A wonderful example of this is coming
from El Salvador and Los Angeles,
11:44
where the mayors in San Salvador
and Los Angeles are collaborating
11:47
on getting ex-gang members
to work with current gang members,
11:51
offering tutoring, education,
11:55
and in the process are helping
incubate cease-fires and truces,
11:58
and we've seen homicide rates
go down in San Salvador,
12:01
once the world's most violent city,
12:04
by 50 percent.
12:06
We can also focus
on hot cities, but also hot spots.
12:07
Place and location matter fundamentally
in shaping violence in our cities.
12:10
Did you know that between
one and two percent
12:14
of street addresses in any fragile city
12:17
can predict up to 99 percent
of violent crime?
12:19
Take the case of São Paulo,
where I've been working.
12:23
It's gone from being Brazil's most
dangerous city to one of its safest,
12:25
and it did this by doubling down
12:29
on information collection,
hot spot mapping, and police reform,
12:31
and in the process, it dropped homicide
by 70 percent in just over 10 years.
12:34
We also got to focus on those hot people.
12:39
It's tragic, but being young,
unemployed, uneducated, male,
12:42
increases the risks
of being killed and killing.
12:46
We have to break this cycle of violence
12:50
and get in there early with our children,
our youngest children,
12:52
and valorize them, not stigmatize them.
12:56
There's wonderful work that's happening
that I've been involved with
12:59
in Kingston, Jamaica
and right here in Rio,
13:02
which is putting education,
employment, recreation
13:04
up front for these high-risk groups,
13:08
and as a result, we're seeing violence
going down in their communities.
13:10
We've also got to make our cities safer,
more inclusive, and livable for all.
13:13
The fact is, social cohesion matters.
13:17
Mobility matters in our cities.
13:21
We've got to get away from this model
of segregation, exclusion,
13:23
and cities with walls.
13:26
My favorite example of how to do this
comes from Medellín.
13:28
When I lived in Colombia
in the late 1990s,
13:30
Medellín was the murder capital
of the world, but it changed course,
13:32
and it did this by deliberately investing
in its low-income and most violent areas
13:36
and integrating them
with the middle-class ones
13:40
through a network of cable cars,
13:43
of public transport,
and first-class infrastructure,
13:44
and in the process, it dropped homicide
by 79 percent in just under two decades.
13:47
And finally, there's technology.
13:52
Technology has enormous
promise but also peril.
13:55
We've seen examples here
of extraordinary innovation,
13:57
and much of it coming from this room,
14:00
The police are engaging
in predictive analytics.
14:02
Citizens are engaging
in new crowdsourcing solutions.
14:04
Even my own group is involved
in developing applications
14:07
to provide more accountability over police
and increase safety among citizens.
14:09
But we need to be careful.
14:14
If I have one single
message for you, it's this:
14:17
There is nothing inevitable
about lethal violence,
14:21
and we can make our cities safer.
14:24
Folks, we have the opportunity
of a lifetime to drop homicidal violence
14:29
in half within our lifetime.
14:35
So I have just one question:
14:38
What are we waiting for?
14:39
Thank you.
14:41
