With fantastic new maps that show interactive, visual representations of urban fragility, Robert Muggah articulates an ancient but resurging idea: cities shouldn't just be the center of economics -- they should also be the foundation of our political lives. Looking around the world, from Syria to Singapore to Seoul and beyond, Muggah submits six principles for how we can build more resilient cities. "Cities are where the future happens first. They're open, creative, dynamic, democratic, cosmopolitan, sexy," Muggah says. "They're the perfect antidote to reactionary nationalism."

So, here's a prediction.

If we get our cities right,
1
3346
2216
00:17
we just might survive the 21st century.
2
5586
2910
00:22
We get them wrong,
3
10579
1491
00:24
and we're done for.
4
12094
1693
00:26
Cities are the most extraordinary
experiment in social engineering
experiment in social engineering
5
14307
3324
00:29
that we humans have ever come up with.

00:32
If you live in a city,
7
20006
1348
00:33
and even if you live in a slum --
8
21378
2189
00:35
which 20 percent of the world's
urban population does --
urban population does --
9
23591
2829
00:38
you're likely to be healthier,
wealthier, better educated
wealthier, better educated
10
26444
2762
00:41
and live longer than your country cousins.
11
29230
2517
00:44
There's a reason why three million people
are moving to cities
are moving to cities
12
32411
3658
00:48
every single week.
13
36093
1219
00:49
Cities are where the future happens first.
14
37877
3175
00:53
They're open, they're creative,
they're dynamic, they're democratic,
they're dynamic, they're democratic,
15
41664
3493
00:57
they're cosmopolitan,
16
45181
1151
00:58
they're sexy.
17
46356
1315
01:00
They're the perfect antidote
to reactionary nationalism.
to reactionary nationalism.
18
48353
4093
01:06
But cities have a dark side.
19
54415
2046
01:09
They take up just three percent
of the world's surface area,
of the world's surface area,
20
57013
3066
01:12
but they account for more than 75 percent
of our energy consumption,
of our energy consumption,
21
60103
3406
01:15
and they emit 80 percent
of our greenhouse gases.
of our greenhouse gases.
22
63533
3100
01:19
There are hundreds of thousands
of people who die in our cities
of people who die in our cities
23
67855
4201
01:24
every single year from violence,
24
72080
1849
01:25
and millions more who are killed
as a result of car accidents
as a result of car accidents
25
73953
3109
01:29
and pollution.
26
77086
1529
01:30
In Brazil, where I live,
27
78639
2084
01:32
we've got 25 of the 50 most homicidal
cities on the planet.
cities on the planet.
28
80747
4259
01:37
And a quarter of our cities
have chronic water shortages --
have chronic water shortages --
29
85497
3347
01:40
and this, in a country with 20 percent
of the known water reserves.
of the known water reserves.
30
88868
3530
01:45
So cities are dual-edged.
31
93329
1752
01:47
Part of the problem is that,
32
95674
1377
01:49
apart from a handful of megacities
in the West and the Far East,
in the West and the Far East,
33
97075
3359
01:52
we don't know that much
about the thousands of cities
about the thousands of cities
34
100458
3354
01:55
in Africa, in Latin America, in Asia,
35
103836
2379
01:58
where 90 percent of all future
population growth is set to take place.
population growth is set to take place.
36
106239
3915
02:03
So why this knowledge gap?
37
111026
1938
02:05
Well, part of the problem
38
113537
1403
02:06
is that we still see the world
through the lens of nation-states.
through the lens of nation-states.
39
114964
3294
02:11
We're still locked
in a 17th-century paradigm
in a 17th-century paradigm
40
119020
4211
02:15
of parochial national sovereignty.
41
123255
2287
02:18
And yet, in the 1600's,
42
126606
1219
02:19
when nation-states were really
coming into their own,
coming into their own,
43
127849
2589
02:22
less than one percent
of the world's population
of the world's population
44
130462
2353
02:24
resided in a city.
45
132839
1452
02:26
Today, it's 54 percent.
46
134315
1628
02:28
And by 2050, it will be
closer to 70 percent.
closer to 70 percent.
47
136603
2325
02:33
So the world has changed.
48
141109
1707
02:34
We have these 193 nation-states,
49
142840
3600
02:38
but we have easily as many cities
that are beginning to rival them
that are beginning to rival them
50
146464
3410
02:41
in power and influence.
51
149898
1531
02:43
Just look at New York.
52
151453
1453
02:44
The Big Apple has 8.5 million people
53
152930
2811
02:47
and an annual budget
of 80 billion dollars.
of 80 billion dollars.
54
155765
3237
02:51
Its GDP is 1.5 trillion,
55
159026
2723
02:53
which puts it higher
than Argentina and Australia,
than Argentina and Australia,
56
161773
3657
02:57
Nigeria and South Africa.
57
165454
1932
03:00
Its roughly 40,000 police officers
58
168189
2521
03:02
means it has one of the largest
police departments in the world,
police departments in the world,
59
170734
3000
03:05
rivaling all but
the largest nation-states.
the largest nation-states.
60
173758
2623
03:09
But cities like New York
61
177653
2021
03:11
or São Paulo
62
179698
1182
03:12
or Johannesburg
63
180904
1220
03:14
or Dhaka
64
182148
1167
03:15
or Shanghai --
65
183339
1173
03:16
they're punching above
their weight economically,
their weight economically,
66
184536
2361
03:18
but below their weight politically.
67
186921
2186
03:21
And that's going to have to change.
68
189131
1850
03:23
Cities are going to have to find
their political voice
their political voice
69
191005
2668
03:25
if we want to change things.
70
193697
1603
03:28
Now, I want to talk to you
a little bit about the risks
a little bit about the risks
71
196131
3043
03:31
that cities are facing --
72
199198
1217
03:32
some of the big mega-risks.
73
200439
1302
03:33
I'm also going to talk to you briefly
about some of the solutions.
about some of the solutions.
74
201765
3198
03:36
I'm going to do this
using a big data visualization
using a big data visualization
75
204987
2448
03:39
that was developed with Carnegie Mellon's
CREATE Lab and my institute,
CREATE Lab and my institute,
76
207459
3463
03:42
along with many, many others.
77
210946
1594
03:44
I want you to first imagine the world
not as made up of nation-states,
not as made up of nation-states,
78
212564
3378
03:47
but as made up of cities.
79
215966
1564
03:50
What you see here is every single city
80
218041
2285
03:52
with a population
of a quarter million people or more.
of a quarter million people or more.
81
220350
3088
03:56
Now, without going into technical detail,
82
224002
1999
03:58
the redder the circle,
the more fragile that city is,
the more fragile that city is,
83
226025
2764
04:00
and the bluer the circle,
the more resilient.
the more resilient.
84
228813
2263
04:03
Fragility occurs when
the social contract comes unstuck.
the social contract comes unstuck.
85
231580
3576
04:07
And what we tend to see is a convergence
of multiple kinds of risks:
of multiple kinds of risks:
86
235634
3420
04:11
income inequality,
87
239078
1279
04:12
poverty,
88
240381
1693
04:14
youth unemployment,
89
242098
1790
04:15
different issues around violence,
90
243912
1839
04:17
even exposure to droughts,
cyclones and earthquakes.
cyclones and earthquakes.
91
245775
3773
04:22
Now obviously, some cities
are more fragile than others.
are more fragile than others.
92
250515
3178
04:26
The good news, if there is any,
93
254966
2085
04:29
is that fragility is not
a permanent condition.
a permanent condition.
94
257075
2676
04:31
Some cities that were once the most
fragile cities in the world,
fragile cities in the world,
95
259775
3346
04:35
like Bogotá in Colombia
96
263145
1391
04:36
or Ciudad Juárez in Mexico,
97
264560
1592
04:38
have now fallen more
around the national average.
around the national average.
98
266176
2732
04:41
The bad news is
that fragility is deepening,
that fragility is deepening,
99
269845
2415
04:44
especially in those parts of the world
that are most vulnerable,
that are most vulnerable,
100
272284
3103
04:47
in North Africa, the Middle East,
101
275411
1634
04:49
in South Asia and Central Asia.
102
277069
1590
04:51
There, we're seeing fragility rising
way beyond scales we've ever seen before.
way beyond scales we've ever seen before.
103
279516
4853
04:56
When cities become too fragile
they can collapse,
they can collapse,
104
284945
3118
05:00
tip over and fail.
105
288087
1429
05:01
And when that happens,
106
289540
1330
05:02
we have explosive forms of migration:
107
290894
2228
05:05
refugees.
108
293936
1229
05:07
There are more than 22 million
refugees in the world today,
refugees in the world today,
109
295767
3994
05:12
more than at any other time
since the second world war.
since the second world war.
110
300281
3239
05:17
Now, there's not one refugee crisis;
111
305512
2411
05:19
there are multiple refugee crises.
112
307947
1827
05:21
And contrary to what
you might read in the news,
you might read in the news,
113
309798
2341
05:24
the vast majority of refugees
aren't fleeing from poor countries
aren't fleeing from poor countries
114
312163
3088
05:27
to wealthy countries,
115
315275
1169
05:28
they're moving from poor cities
into even poorer cities --
into even poorer cities --
116
316468
2986
05:31
often, cities nearby.
117
319478
1609
05:33
Every single dot on this map
represents an agonizing story
represents an agonizing story
118
321815
4387
05:38
of struggle and survival.
119
326226
1788
05:40
But I want to briefly tell you
about what's not on that map,
about what's not on that map,
120
328038
2810
05:42
and that's internal displacement.
121
330872
1939
05:44
There are more than 36 million people
who have been internally displaced
who have been internally displaced
122
332835
3808
05:48
around the world.
123
336667
1168
05:49
These are people living
in refugee-like conditions,
in refugee-like conditions,
124
337859
2495
05:52
but lacking the equivalent international
protection and assistance.
protection and assistance.
125
340378
3395
05:55
And to understand their plight,
126
343797
1592
05:57
I want to zoom in briefly on Syria.
127
345413
2105
06:01
Syria suffered one of the worst droughts
in its history between 2007 and 2010.
in its history between 2007 and 2010.
128
349523
4655
06:06
More than 75 percent of its agriculture
and 85 percent of its livestock
and 85 percent of its livestock
129
354202
3942
06:10
were wiped out.
130
358168
1452
06:11
And in the process,
over a million people moved into cities
over a million people moved into cities
131
359644
3039
06:14
like Aleppo, Damascus and Homs.
132
362707
2306
06:17
As food prices began to rise,
133
365832
2033
06:19
you also had equivalent levels
of social unrest.
of social unrest.
134
367889
2478
06:23
And when the regime of President Assad
began cracking down,
began cracking down,
135
371384
3404
06:26
you had an explosion of refugees.
136
374812
2398
06:30
You also had over six million
internally displaced people,
internally displaced people,
137
378347
3200
06:33
many of whom when on to become refugees.
138
381571
2366
06:35
And they didn't just move
to neighboring countries like Jordan
to neighboring countries like Jordan
139
383961
3060
06:39
or Lebanon or Turkey.
140
387045
1602
06:41
They also moved up north
towards Western Europe.
towards Western Europe.
141
389172
2656
06:44
See, over 1.4 million Syrians
made the perilous journey
made the perilous journey
142
392690
3776
06:48
through the Mediterranean
and up through Turkey
and up through Turkey
143
396490
2723
06:51
to find their way
into two countries, primarily:
into two countries, primarily:
144
399237
2365
06:53
Germany and Sweden.
145
401626
1801
06:57
Now, climate change --
146
405048
1418
06:58
not just drought, but also sea level rise,
147
406490
2710
07:01
is probably one of the most severe
existential threats
existential threats
148
409224
2945
07:04
that cities face.
149
412193
1291
07:05
That's because two-thirds
of the world's cities are coastal.
of the world's cities are coastal.
150
413508
3072
07:10
Over 1.5 billion people live in low-lying,
flood-prone coastal areas.
flood-prone coastal areas.
151
418156
5236
07:15
What you see here is a map
that shows sea level rise
that shows sea level rise
152
423981
2877
07:18
in relation to changes in temperature.
153
426882
2056
07:21
Climate scientists predict
that we're going to see
that we're going to see
154
429953
2408
07:24
anywhere between three
and 30 feet of sea level rise
and 30 feet of sea level rise
155
432385
2537
07:26
this side of the century.
156
434946
1552
07:28
And it's not just low island nation-states
that are going to suffer --
that are going to suffer --
157
436522
3334
07:31
Kiribati or the Maldives
or the Solomons or Sri Lanka --
or the Solomons or Sri Lanka --
158
439880
3340
07:35
and they will suffer,
159
443244
1648
07:36
but also massive cities like Dhaka,
160
444916
1991
07:39
like Hong Kong,
161
447542
1224
07:40
like Shanghai.
162
448790
1260
07:42
Cities of 10, 20, 30 million
people or more
people or more
163
450074
3051
07:45
are literally going to be wiped off
the face of this earth.
the face of this earth.
164
453149
3336
07:48
They're going to have to adapt,
or they're going to die.
or they're going to die.
165
456984
2725
07:52
I want to take you also
all the way over to the West,
all the way over to the West,
166
460683
2557
07:55
because this isn't just a problem
in Asia or Africa or Latin America,
in Asia or Africa or Latin America,
167
463264
3291
07:58
this is a problem also in the West.
168
466579
1817
08:00
This is Miami.
169
468420
1156
08:01
Many of you know Miami
is one of the wealthiest cities
is one of the wealthiest cities
170
469600
2571
08:04
in the United States;
171
472195
1153
08:05
it's also one of the most flood-prone.
172
473372
1838
08:07
That's been made painfully evident
by natural disasters throughout 2017.
by natural disasters throughout 2017.
173
475234
3430
08:10
But Miami is built
on porous limestone -- a swamp.

174
478688
2408
08:13
There's no way any kind of flood barrier
175
481120
1976
08:15
is going to keep
the water from seeping in.
the water from seeping in.
176
483120
2336
08:17
As we scroll back,
177
485480
1206
08:18
and we look across the Caribbean
and along the Gulf,
and along the Gulf,
178
486710
2692
08:21
we begin to realize
179
489426
1154
08:22
that those cities that have suffered
worst from natural crises --
worst from natural crises --
180
490604
3116
08:25
Port-au-Prince, New Orleans, Houston --
181
493744
3004
08:28
as severe and as awful
as those situations have been,
as those situations have been,
182
496772
2599
08:31
they're a dress rehearsal
for what's to come.
for what's to come.
183
499395
2468
08:34
No city is an island.
184
502855
1681
08:36
Every city is connected
to its rural hinterland
to its rural hinterland
185
504560
2256
08:38
in complex ways --
186
506840
1152
08:40
often, in relation
to the production of food.

187
508016

08:42
I want to take you to the northern part
of the Amazon, in Rondônia.
of the Amazon, in Rondônia.
188
510842

08:46
This is one of the world's largest
terrestrial carbon sinks,
terrestrial carbon sinks,
189
514240
2881
08:49
processing millions of carbon
every single year.
every single year.
190
517145
2262
08:51
What you see here is a single road
over a 30-year period.
over a 30-year period.
191
519431
2845
08:54
On either side you see land being
cleared for pasture, for cattle,
cleared for pasture, for cattle,
192
522300
3865
08:58
but also for soy and sugar production.
193
526189
2195
09:00
You're seeing deforestation
on a massive scale.
on a massive scale.
194
528981
2625
09:04
The red area here implies a net loss
of forest over the last 14 years.

195
532673
4563
09:09
The blue, if you could see it --
there's not much --
there's not much --
196
537854
2547
09:12
implies there's been an incremental gain.
197
540425
2065
09:15
Now, as grim and gloomy
as the situation is -- and it is --
as the situation is -- and it is --
198
543275
4021
09:19
there is a little bit of hope.
199
547320
1566
09:21
See, the Brazilian government,
200
549366
1492
09:22
from the national to the state
to the municipal level,
to the municipal level,
201
550882
2567
09:25
has also introduced a whole range --
a lattice -- of parks and protected areas.

202
553473
3817
09:29
And while not perfect,
and not always limiting encroachment,
and not always limiting encroachment,
203
557314
2976
09:32
they have served
to tamp back deforestation.
to tamp back deforestation.
204
560314
2935
09:35
The same applies not just in Brazil
but all across the Americas,
but all across the Americas,
205
563791
3228
09:39
into the United States, Canada
and around the world.
and around the world.
206
567043
2528
09:41
So let's talk about solutions.
207
569595
2096
09:44
Despite climate denial
at the highest levels,
at the highest levels,
208
572917
3472
09:48
cities are taking action.
209
576413
1809
09:50
You know, when the US pulled out
of the Paris Climate Agreement,
of the Paris Climate Agreement,
210
578246
3419
09:53
hundreds of cities in the United States
and thousands more around the world
and thousands more around the world
211
581689
3634
09:57
doubled down on their climate commitments.
212
585347
2077
10:00
(Applause)
213
588005
3614
10:06
And when the White House cracked down
on so-called "undocumented migrants"
on so-called "undocumented migrants"
214
594924
4437
10:11
in sanctuary cities,
215
599385
1195
10:12
hundreds of cities and counties
and states sat up in defiance
and states sat up in defiance
216
600604
2963
10:15
and refused to enact that order.
217
603591
2091
10:17
(Applause)
218
605706
3177
10:22
So cities are and can take action.
219
610033
2714
10:25
But we're going to need
to see a lot more of it,
to see a lot more of it,
220
613731
2842
10:28
especially in the global south.
221
616597
1926
10:30
You see, parts of Africa
and Latin America are urbanizing
and Latin America are urbanizing
222
618547
3790
10:34
before they industrialize.
223
622361
1352
10:35
They're growing at three times
the global average
the global average
224
623737
2450
10:38
in terms their population.
225
626211
1463
10:40
And this is putting enormous strain
on infrastructure and services.
on infrastructure and services.
226
628532
3424
10:44
Now, there is a golden opportunity.
227
632514
3131
10:48
It's a small opportunity but a golden one:
in the next 10 to 20 years,
in the next 10 to 20 years,
228
636134
3325
10:51
to really start designing in
principles of resilience into our cities.
principles of resilience into our cities.
229
639483
3544
10:55
There's not one single way of doing this,
230
643051
2465
10:57
but there are a number of ways
that are emerging.
that are emerging.
231
645540
2793
11:00
And I've spoken with hundreds
of urban planners,
of urban planners,
232
648357
2613
11:02
development specialists,
233
650994
1434
11:04
architects and civic activists,
234
652452
2368
11:06
and a number of recurring
principles keep coming out.
principles keep coming out.
235
654844
2643
11:09
I just want to pass on six.
236
657511
1790
11:12
First: cities need a plan
237
660186
2791
11:15
and a strategy to implement it.
238
663001
1873
11:16
I mean, it sounds crazy,
239
664898
1219
11:18
but the vast majority of world cities
don't actually have a plan
don't actually have a plan
240
666141
3107
11:21
or a vision.
241
669272
1155
11:22
They're too busy putting out daily fires
to think ahead strategically.
to think ahead strategically.
242
670451
3334
11:25
I mean, every city wants to be creative,
243
673809
2009
11:27
happy, liveable, resilient --
244
675842
2366
11:30
who doesn't?
245
678232
1278
11:31
The challenge is, how do you get there?
246
679534
1870
11:33
And urban governance plays a key role.
247
681428
2240
11:35
You could do worse than take a page
from the book of Singapore.
from the book of Singapore.
248
683692
3024
11:38
In 1971, Singapore set
a 50-year urban strategy
a 50-year urban strategy
249
686740
3239
11:42
and renews it every five years.
250
690003
2318
11:45
What Singapore teaches us
is not just the importance of continuity,
is not just the importance of continuity,
251
693189
3531
11:48
but also the critical role
of autonomy and discretion.
of autonomy and discretion.
252
696744
3247
11:52
Cities need the power
to be able to issue debt,
to be able to issue debt,
253
700747
3025
11:55
to raise taxes,
254
703796
1214
11:57
to zone effectively,
255
705034
1151
11:58
to build affordable housing.
256
706209
1656
12:01
What cities need is nothing less
than a devolution revolution,
than a devolution revolution,
257
709095
4403
12:05
and this is going to require
renegotiating the terms of the contract
renegotiating the terms of the contract
258
713522
3216
12:08
with a nation-state.
259
716762
1359
12:10
Second:
260
718765
1274
12:12
you've got to go green.
261
720063
1691
12:13
Cities are already leading
global decarbonization efforts.
global decarbonization efforts.
262
721778
3063
12:16
They're investing in congestion
pricing schemes,
pricing schemes,
263
724865
2262
12:19
in climate reduction emission targets,
264
727151
2325
12:21
in biodiversity, in parks
and bikeways and walkways
and bikeways and walkways
265
729500
3960
12:25
and everything in between.
266
733484
1259
12:26
There's an extraordinary menu of options
they have to choose from.
they have to choose from.
267
734767
3153
12:29
One of the great things is,
268
737944
1294
12:31
cities are already investing heavily
in renewables -- in solar and wind --
in renewables -- in solar and wind --
269
739262
3521
12:34
not just in North America, but especially
in Western Europe and parts of Asia.
in Western Europe and parts of Asia.
270
742807
3733
12:38
There are more than 8,000 cities
right now in the world today
right now in the world today
271
746564
2903
12:41
with solar plants.
272
749491
1170
12:42
There are 300 cities that have declared
complete energy autonomy.
complete energy autonomy.
273
750685
4199
12:46
One of my favorite stories
comes from Medellín,
comes from Medellín,
274
754908
2403
12:49
which invested in a municipal
hydroelectric plant,
hydroelectric plant,
275
757335
3133
12:52
which doesn't only service
its local needs,
its local needs,
276
760492
2228
12:54
but allows the city to sell excess energy
back onto the national grid.
back onto the national grid.
277
762744
3323
12:58
And it's not alone.
278
766091
1168
12:59
There are a thousand
other cities just like it.
other cities just like it.
279
767283
2536
13:02
Third: invest in integrated
and multi-use solutions.
and multi-use solutions.
280
770389
3790
13:06
The most successful cities are those
that are going to invest in solutions
that are going to invest in solutions
281
774956
3569
13:10
that don't solve just one problem,
but that solve multiple problems.
but that solve multiple problems.
282
778549
3235
13:13
Take the case of integrated
public transport.
public transport.
283
781808
3202
13:17
When done well --
284
785704
1314
13:19
rapid bus transit,
285
787042
1385
13:20
light rail,
286
788451
1343
13:21
bikeways, walkways, boatways --
287
789818
2405
13:24
these can dramatically reduce
emissions and congestion.
emissions and congestion.
288
792247
3346
13:28
But they can do a lot more than that.
289
796297
1857
13:30
They can improve public health.
290
798178
1675
13:31
They can reduce dispersion.
291
799877
1644
13:33
They can even increase safety.
292
801545
1629
13:36
A great example of this comes from Seoul.
293
804109
1995
13:38
You see, Seoul's population doubled
over the last 30 years,
over the last 30 years,
294
806128
3981
13:42
but the footprint barely changed.
295
810133
2196
13:44
How?
296
812353
1401
13:45
Well, 75 percent
of Seoul's residents get to work
of Seoul's residents get to work
297
813778
2835
13:48
using what's been described as
298
816637
1439
13:50
one of the most extraordinary
public transport systems
public transport systems
299
818100
2574
13:52
in the world.
300
820698
1151
13:53
And Seoul used to be car country.
301
821873
1700
13:56
Next, fourth:
302
824859
1438
13:59
build densely but also sustainably.
303
827530
2812
14:03
The death of all cities is the sprawl.
304
831057
3101
14:06
Cities need to know
how to build resiliently,
how to build resiliently,
305
834667
2175
14:08
but also in a way that's inclusive.
306
836866
1791
14:11
This is a picture right here
of Dallas-Fort Worth.
of Dallas-Fort Worth.
307
839095
3751
14:14
And what you see is its population
also doubled over the last 30 years.
also doubled over the last 30 years.
308
842870
4314
14:19
But as you can see, it spread
into edge cities and suburbia
into edge cities and suburbia
309
847832
3130
14:22
as far as the eye can see.
310
850986
1610
14:25
Cities need to know when not to build,
311
853121
2210
14:27
so as not to reproduce urban sprawl
312
855355
2331
14:29
and slums of downward accountability.
313
857710
1940
14:32
The problem with Dallas-Forth Worth is
314
860377
1960
14:34
just five percent of its residents get
to work using public transport -- five.
to work using public transport -- five.
315
862361
4757
14:39
Ninety-five percent use cars,
316
867142
1458
14:40
which partly explains why it's got
some of the longest commuting times
some of the longest commuting times
317
868624
3415
14:44
in North America.
318
872063
1301
14:45
Singapore, by contrast, got it right.
319
873388
2065
14:47
They built vertically
320
875477
1167
14:48
and built in affordable housing to boot.
321
876668
1963
14:51
Fifth: steal.
322
879989
1843
14:54
The smartest cities are nicking,
pilfering, stealing,
pilfering, stealing,
323
882987
2617
14:57
left, right and center.
324
885628
1160
14:58
They don't have time to waste.
325
886812
1484
15:00
They need tomorrow's technology today,
326
888320
1983
15:02
and they're going
to leapfrog to get there.
to leapfrog to get there.
327
890327
2005
15:04
This is New York,
328
892356
1155
15:05
but it's not just New York
that's doing a lot of stealing,
that's doing a lot of stealing,
329
893535
2834
15:08
it's Singapore, it's Seoul, it's Medellín.
330
896393
2064
15:10
The urban renaissance
is only going to be enabled
is only going to be enabled
331
898481
2337
15:12
when cities start borrowing
from one another.
from one another.
332
900842
2175
15:15
And finally: work in global coalitions.
333
903041
2525
15:18
You know, there are more than 200
inner-city coalitions in the world today.
inner-city coalitions in the world today.
334
906008
3640
15:21
There are more city coalitions
335
909672
1547
15:23
than there are coalitions
for nation-states.
for nation-states.
336
911243
2334
15:26
Just take a look at the Global
Parliament of Mayors,
Parliament of Mayors,
337
914272
2503
15:28
set up by the late Ben Barber,
338
916799
1449
15:30
who was driving an urban rights movement.
339
918272
2041
15:32
Or consider the C40,
340
920337
1494
15:33
a marvelous network of cities
that has gathered thousands together
that has gathered thousands together
341
921855
3411
15:37
to deliver clean energy.
342
925290
1437
15:39
Or look at the World Economic Forum,
343
927092
1763
15:40
which is developing smart city protocols.
344
928879
1997
15:42
Or the 100 Resilient Cities initiative,
345
930900
1882
15:44
which is leading a resilience revival.
346
932806
2003
15:47
ICLEI, UCLG, Metropolis --
347
935945
3481
15:51
these are the movements of the future.
348
939450
2677
15:54
What they all realize
is that when cities work together,
is that when cities work together,
349
942151
2786
15:56
they can amplify their voice,
350
944961
1857
15:59
not just on the national stage,

ABOUT THE SPEAKER
Robert Muggah - Megacities expertRobert Muggah creates tools to understand cycles of violence in urban environments and opens dialogues on ways to confront them globally.
Why you should listen
Robert Muggah drills down through shadowy data on arms trafficking, urban violence and resilience in search of answers for a rapidly urbanizing society’s most troubling questions: Why are cities so violent, and increasingly fragile? Why are conflicts within nations replacing conflicts between them? And what strategies can we implement to reduce violence?
Muggah's high-tech toolkit includes new ways for citizens to collect, collate and understand data, such as the mapping arms data (MAD) tool. As the research director of the Igarapé Institute and the SecDev Foundation, he developed the tool in collaboration with the Peace Research Institute Oslo and with Google Ideas, winning accolades for the transparency it brings to the debate.
