How megacities are changing the map of the world
-
0:01 - 0:06I want you to reimagine
how life is organized on earth. -
0:07 - 0:11Think of the planet
like a human body that we inhabit. -
0:12 - 0:17The skeleton is the transportation system
of roads and railways, -
0:17 - 0:20bridges and tunnels, air and seaports
-
0:20 - 0:23that enable our mobility
across the continents. -
0:23 - 0:26The vascular system that powers the body
-
0:26 - 0:29are the oil and gas pipelines
and electricity grids. -
0:29 - 0:30that distribute energy.
-
0:31 - 0:34And the nervous system of communications
-
0:34 - 0:37is the Internet cables,
satellites, cellular networks -
0:37 - 0:41and data centers that allow
us to share information. -
0:41 - 0:46This ever-expanding infrastructural matrix
-
0:46 - 0:51already consists of 64 million
kilometers of roads, -
0:51 - 0:54four million kilometers of railways,
-
0:54 - 0:57two million kilometers of pipelines
-
0:57 - 1:00and one million kilometers
of Internet cables. -
1:01 - 1:04What about international borders?
-
1:05 - 1:09We have less than
500,000 kilometers of borders. -
1:10 - 1:12Let's build a better map of the world.
-
1:13 - 1:16And we can start by overcoming
some ancient mythology. -
1:17 - 1:20There's a saying with which
all students of history are familiar: -
1:21 - 1:24"Geography is destiny."
-
1:24 - 1:25Sounds so grave, doesn't it?
-
1:26 - 1:28It's such a fatalistic adage.
-
1:28 - 1:33It tells us that landlocked countries
are condemned to be poor, -
1:33 - 1:36that small countries
cannot escape their larger neighbors, -
1:36 - 1:39that vast distances are insurmountable.
-
1:40 - 1:43But every journey I take around the world,
-
1:43 - 1:47I see an even greater force
sweeping the planet: -
1:48 - 1:49connectivity.
-
1:50 - 1:54The global connectivity revolution,
in all of its forms -- -
1:54 - 1:57transportation, energy
and communications -- -
1:57 - 2:01has enabled such a quantum leap
in the mobility of people, -
2:01 - 2:04of goods, of resources, of knowledge,
-
2:04 - 2:08such that we can no longer even think
of geography as distinct from it. -
2:09 - 2:13In fact, I view the two forces
as fusing together -
2:13 - 2:15into what I call "connectography."
-
2:16 - 2:20Connectography represents a quantum leap
-
2:20 - 2:24in the mobility of people,
resources and ideas, -
2:24 - 2:25but it is an evolution,
-
2:26 - 2:32an evolution of the world
from political geography, -
2:32 - 2:35which is how we legally divide the world,
-
2:36 - 2:38to functional geography,
-
2:38 - 2:41which is how we actually use the world,
-
2:41 - 2:45from nations and borders,
to infrastructure and supply chains. -
2:46 - 2:48Our global system is evolving
-
2:49 - 2:53from the vertically integrated
empires of the 19th century, -
2:53 - 2:57through the horizontally interdependent
nations of the 20th century, -
2:57 - 3:02into a global network civilization
in the 21st century. -
3:03 - 3:07Connectivity, not sovereignty,
-
3:07 - 3:11has become the organizing principle
of the human species. -
3:11 - 3:14(Applause)
-
3:15 - 3:19We are becoming
this global network civilization -
3:19 - 3:21because we are literally building it.
-
3:22 - 3:25All of the world's defense budgets
and military spending taken together -
3:25 - 3:28total just under
two trillion dollars per year. -
3:28 - 3:31Meanwhile, our global
infrastructure spending -
3:31 - 3:34is projected to rise
to nine trillion dollars per year -
3:34 - 3:36within the coming decade.
-
3:36 - 3:37And, well, it should.
-
3:37 - 3:40We have been living
off an infrastructure stock -
3:40 - 3:43meant for a world population
of three billion, -
3:44 - 3:47as our population has crossed
seven billion to eight billion -
3:47 - 3:49and eventually nine billion and more.
-
3:49 - 3:54As a rule of thumb, we should spend
about one trillion dollars -
3:54 - 3:58on the basic infrastructure needs
of every billion people in the world. -
3:59 - 4:02Not surprisingly, Asia is in the lead.
-
4:03 - 4:06In 2015, China announced the creation
-
4:06 - 4:09of the Asian Infrastructure
Investment Bank, -
4:10 - 4:13which together with a network
of other organizations -
4:13 - 4:16aims to construct a network
of iron and silk roads, -
4:17 - 4:19stretching from Shanghai to Lisbon.
-
4:20 - 4:24And as all of this topographical
engineering unfolds, -
4:24 - 4:29we will likely spend more
on infrastructure in the next 40 years, -
4:29 - 4:33we will build more infrastructure
in the next 40 years, -
4:33 - 4:35than we have in the past 4,000 years.
-
4:37 - 4:39Now let's stop and think
about it for a minute. -
4:40 - 4:44Spending so much more on building
the foundations of global society -
4:44 - 4:47rather than on the tools to destroy it
-
4:47 - 4:50can have profound consequences.
-
4:50 - 4:53Connectivity is how
we optimize the distribution -
4:53 - 4:55of people and resources around the world.
-
4:55 - 5:00It is how mankind comes to be more
than just the sum of its parts. -
5:01 - 5:03I believe that is what is happening.
-
5:05 - 5:09Connectivity has a twin megatrend
in the 21st century: -
5:09 - 5:11planetary urbanization.
-
5:12 - 5:15Cities are the infrastructures
that most define us. -
5:16 - 5:19By 2030, more than two thirds
of the world's population -
5:19 - 5:20will live in cities.
-
5:20 - 5:23And these are not
mere little dots on the map, -
5:23 - 5:27but they are vast archipelagos
stretching hundreds of kilometers. -
5:27 - 5:29Here we are in Vancouver,
-
5:29 - 5:31at the head of the Cascadia Corridor
-
5:31 - 5:34that stretches south
across the US border to Seattle. -
5:35 - 5:37The technology powerhouse
of Silicon Valley -
5:37 - 5:40begins north of San Francisco
down to San Jose -
5:40 - 5:42and across the bay to Oakland.
-
5:42 - 5:45The sprawl of Los Angeles
now passes San Diego -
5:45 - 5:47across the Mexican border to Tijuana.
-
5:47 - 5:50San Diego and Tijuana
now share an airport terminal -
5:50 - 5:52where you can exit into either country.
-
5:52 - 5:56Eventually, a high-speed rail network
may connect the entire Pacific spine. -
5:58 - 6:02America's northeastern megalopolis
begins in Boston through New York -
6:02 - 6:04and Philadelphia to Washington.
-
6:04 - 6:06It contains more than 50 million people
-
6:06 - 6:09and also has plans
for a high-speed rail network. -
6:09 - 6:13But Asia is where we really see
the megacities coming together. -
6:13 - 6:18This continuous strip of light
from Tokyo through Nagoya to Osaka -
6:18 - 6:20contains more than 80 million people
-
6:20 - 6:21and most of Japan's economy.
-
6:22 - 6:25It is the world's largest megacity.
-
6:25 - 6:26For now.
-
6:27 - 6:29But in China, megacity clusters
are coming together -
6:29 - 6:32with populations
reaching 100 million people. -
6:32 - 6:34The Bohai Rim around Beijing,
-
6:34 - 6:36The Yangtze River Delta around Shanghai
-
6:36 - 6:38and the Pearl River Delta,
-
6:38 - 6:41stretching from Hong Kong
north to Guangzhou. -
6:41 - 6:42And in the middle,
-
6:42 - 6:45the Chongqing-Chengdu megacity cluster,
-
6:45 - 6:48whose geographic footprint
is almost the same size -
6:48 - 6:49as the country of Austria.
-
6:51 - 6:53And any number of these megacity clusters
-
6:53 - 6:56has a GDP approaching
two trillion dollars -- -
6:56 - 6:59that's almost the same
as all of India today. -
7:00 - 7:05So imagine if our global diplomatic
institutions, such as the G20, -
7:05 - 7:09were to base their membership
on economic size -
7:09 - 7:11rather than national representation.
-
7:11 - 7:15Some Chinese megacities
may be in and have a seat at the table, -
7:15 - 7:19while entire countries,
like Argentina or Indonesia would be out. -
7:20 - 7:24Moving to India, whose population
will soon exceed that of China, -
7:24 - 7:26it too has a number of megacity clusters,
-
7:26 - 7:29such as the Delhi Capital Region
-
7:29 - 7:30and Mumbai.
-
7:30 - 7:31In the Middle East,
-
7:31 - 7:34Greater Tehran is absorbing
one third of Iran's population. -
7:34 - 7:36Most of Egypt's 80 million people
-
7:36 - 7:39live in the corridor
between Cairo and Alexandria. -
7:39 - 7:43And in the gulf, a necklace
of city-states is forming, -
7:43 - 7:45from Bahrain and Qatar,
-
7:45 - 7:48through the United Arab Emirates
to Muscat in Oman. -
7:49 - 7:50And then there's Lagos,
-
7:51 - 7:55Africa's largest city
and Nigeria's commercial hub. -
7:55 - 7:57It has plans for a rail network
-
7:57 - 8:01that will make it the anchor
of a vast Atlantic coastal corridor, -
8:01 - 8:04stretching across Benin, Togo and Ghana,
-
8:04 - 8:08to Abidjan, the capital
of the Ivory Coast. -
8:08 - 8:11But these countries are suburbs of Lagos.
-
8:12 - 8:14In a megacity world,
-
8:14 - 8:17countries can be suburbs of cities.
-
8:19 - 8:25By 2030, we will have as many
as 50 such megacity clusters in the world. -
8:25 - 8:27So which map tells you more?
-
8:27 - 8:30Our traditional map
of 200 discrete nations -
8:30 - 8:32that hang on most of our walls,
-
8:32 - 8:35or this map of the 50 megacity clusters?
-
8:36 - 8:39And yet, even this is incomplete
-
8:39 - 8:43because you cannot understand
any individual megacity -
8:43 - 8:46without understanding
its connections to the others. -
8:47 - 8:49People move to cities to be connected,
-
8:49 - 8:52and connectivity
is why these cities thrive. -
8:53 - 8:57Any number of them,
such as Sao Paulo or Istanbul or Moscow, -
8:57 - 9:01has a GDP approaching or exceeding
one third of one half -
9:01 - 9:03of their entire national GDP.
-
9:04 - 9:06But equally importantly,
-
9:06 - 9:09you cannot calculate
any of their individual value -
9:09 - 9:12without understanding
the role of the flows of people, -
9:12 - 9:14of finance, of technology
-
9:14 - 9:16that enable them to thrive.
-
9:17 - 9:19Take the Gauteng province of South Africa,
-
9:19 - 9:23which contains Johannesburg
and the capital Pretoria. -
9:23 - 9:26It too represents just over
a third of South Africa's GDP. -
9:27 - 9:30But equally importantly,
it is home to the offices -
9:30 - 9:33of almost every single
multinational corporation -
9:33 - 9:35that invests directly into South Africa
-
9:35 - 9:38and indeed, into the entire
African continent. -
9:39 - 9:42Cities want to be part
of global value chains. -
9:42 - 9:46They want to be part
of this global division of labor. -
9:46 - 9:48That is how cities think.
-
9:49 - 9:50I've never met a mayor who said to me,
-
9:50 - 9:52"I want my city to be cut off."
-
9:53 - 9:56They know that their cities belong as much
-
9:56 - 10:01to the global network civilization
as to their home countries. -
10:03 - 10:06Now, for many people,
urbanization causes great dismay. -
10:07 - 10:09They think cities are wrecking the planet.
-
10:10 - 10:11But right now,
-
10:11 - 10:15there are more than 200
intercity learning networks thriving. -
10:15 - 10:19That is as many as the number
of intergovernmental organizations -
10:19 - 10:20that we have.
-
10:20 - 10:24And all of these intercity networks
are devoted to one purpose, -
10:24 - 10:29mankind's number one priority
in the 21st century: -
10:29 - 10:31sustainable urbanization.
-
10:33 - 10:34Is it working?
-
10:35 - 10:36Let's take climate change.
-
10:36 - 10:39We know that summit after summit
in New York and Paris -
10:39 - 10:42is not going to reduce
greenhouse gas emissions. -
10:43 - 10:46But what we can see
is that transferring technology -
10:46 - 10:48and knowledge and policies between cities
-
10:49 - 10:53is how we've actually begun to reduce
the carbon intensity of our economies. -
10:53 - 10:55Cities are learning from each other.
-
10:55 - 10:58How to install zero-emissions buildings,
-
10:58 - 11:01how to deploy electric
car-sharing systems. -
11:01 - 11:02In major Chinese cities,
-
11:02 - 11:05they're imposing quotas
on the number of cars on the streets. -
11:05 - 11:07In many Western cities,
-
11:07 - 11:09young people don't even
want to drive anymore. -
11:10 - 11:12Cities have been part of the problem,
-
11:12 - 11:14now they are part of the solution.
-
11:15 - 11:19Inequality is the other great challenge
to achieving sustainable urbanization. -
11:20 - 11:23When I travel through megacities
from end to end -- -
11:23 - 11:25it takes hours and days --
-
11:26 - 11:29I experience the tragedy
of extreme disparity -
11:29 - 11:31within the same geography.
-
11:32 - 11:35And yet, our global stock
of financial assets -
11:35 - 11:37has never been larger,
-
11:37 - 11:40approaching 300 trillion dollars.
-
11:40 - 11:44That's almost four times
the actual GDP of the world. -
11:45 - 11:49We have taken on such enormous debts
since the financial crisis, -
11:49 - 11:52but have we invested them
in inclusive growth? -
11:53 - 11:55No, not yet.
-
11:56 - 12:00Only when we build sufficient,
affordable public housing, -
12:00 - 12:03when we invest in robust
transportation networks -
12:03 - 12:07to allow people to connect to each other
both physically and digitally, -
12:07 - 12:10that's when our divided
cities and societies -
12:10 - 12:12will come to feel whole again.
-
12:12 - 12:14(Applause)
-
12:16 - 12:19And that is why infrastructure
has just been included -
12:19 - 12:21in the United Nations
Sustainable Development Goals, -
12:21 - 12:24because it enables all the others.
-
12:24 - 12:26Our political and economic leaders
-
12:26 - 12:29are learning that connectivity
is not charity, -
12:29 - 12:30it's opportunity.
-
12:31 - 12:34And that's why our financial community
needs to understand -
12:34 - 12:39that connectivity is the most
important asset class of the 21st century. -
12:40 - 12:44Now, cities can make the world
more sustainable, -
12:45 - 12:47they can make the world more equitable,
-
12:47 - 12:50I also believe that
connectivity between cities -
12:50 - 12:52can make the world more peaceful.
-
12:52 - 12:56If we look at regions of the world
with dense relations across borders, -
12:56 - 12:59we see more trade, more investment
-
12:59 - 13:01and more stability.
-
13:01 - 13:03We all know the story
of Europe after World War II, -
13:03 - 13:06where industrial integration
kicked off a process -
13:06 - 13:08that gave rise to today's
peaceful European Union. -
13:09 - 13:12And you can see that Russia, by the way,
-
13:12 - 13:16is the least connected of major powers
in the international system. -
13:16 - 13:20And that goes a long way
towards explaining the tensions today. -
13:20 - 13:23Countries that have
less stake in the system -
13:23 - 13:25also have less to lose in disturbing it.
-
13:27 - 13:30In North America, the lines
that matter most on the map -
13:30 - 13:33are not the US-Canada border
or the US-Mexico border, -
13:33 - 13:37but the dense network of roads
and railways and pipelines -
13:37 - 13:40and electricity grids
and even water canals -
13:40 - 13:44that are forming an integrated
North American union. -
13:44 - 13:48North America does not need more walls,
it needs more connections. -
13:48 - 13:51(Applause)
-
13:56 - 14:00But the real promise of connectivity
is in the postcolonial world. -
14:00 - 14:05All of those regions where borders
have historically been the most arbitrary -
14:05 - 14:07and where generations of leaders
-
14:07 - 14:09have had hostile relations
with each other. -
14:09 - 14:12But now a new group of leaders
has come into power -
14:12 - 14:13and is burying the hatchet.
-
14:14 - 14:17Let's take Southeast Asia,
where high-speed rail networks -
14:17 - 14:19are planned to connect
Bangkok to Singapore -
14:19 - 14:22and trade corridors
from Vietnam to Myanmar. -
14:22 - 14:28Now this region of 600 million people
coordinates its agricultural resources -
14:28 - 14:29and its industrial output.
-
14:30 - 14:34It is evolving
into what I call a Pax Asiana, -
14:34 - 14:37a peace among Southeast Asian nations.
-
14:38 - 14:41A similar phenomenon
is underway in East Africa, -
14:41 - 14:43where a half dozen countries
-
14:43 - 14:46are investing in railways
and multimodal corridors -
14:46 - 14:49so that landlocked countries
can get their goods to market. -
14:49 - 14:52Now these countries
coordinate their utilities -
14:52 - 14:54and their investment policies.
-
14:54 - 14:58They, too, are evolving
into a Pax Africana. -
14:59 - 15:02One region we know could
especially use this kind of thinking -
15:02 - 15:03is the Middle East.
-
15:04 - 15:06As Arab states tragically collapse,
-
15:06 - 15:09what is left behind
but the ancient cities, -
15:09 - 15:12such as Cairo, Beirut and Baghdad?
-
15:12 - 15:17In fact, the nearly
400 million people of the Arab world -
15:17 - 15:19are almost entirely urbanized.
-
15:19 - 15:21As societies, as cities,
-
15:21 - 15:23they are either water rich or water poor,
-
15:23 - 15:25energy rich or energy poor.
-
15:26 - 15:29And the only way
to correct these mismatches -
15:29 - 15:32is not through more wars and more borders,
-
15:32 - 15:35but through more connectivity
of pipelines and water canals. -
15:36 - 15:40Sadly, this is not yet
the map of the Middle East. -
15:40 - 15:41But it should be,
-
15:43 - 15:46a connected Pax Arabia,
-
15:47 - 15:48internally integrated
-
15:48 - 15:53and productively connected
to its neighbors: Europe, Asia and Africa. -
15:53 - 15:56Now, it may not seem like connectivity
is what we want right now -
15:56 - 15:58towards the world's most turbulent region.
-
15:59 - 16:02But we know from history
that more connectivity is the only way -
16:02 - 16:05to bring about stability in the long run.
-
16:05 - 16:07Because we know
that in region after region, -
16:07 - 16:10connectivity is the new reality.
-
16:10 - 16:14Cities and countries
are learning to aggregate -
16:14 - 16:16into more peaceful and prosperous wholes.
-
16:18 - 16:20But the real test is going to be Asia.
-
16:21 - 16:24Can connectivity overcome
the patterns of rivalry -
16:24 - 16:27among the great powers of the Far East?
-
16:27 - 16:31After all, this is where World War III
is supposed to break out. -
16:32 - 16:35Since the end of the Cold War,
a quarter century ago, -
16:35 - 16:38at least six major wars
have been predicted for this region. -
16:38 - 16:40But none have broken out.
-
16:41 - 16:43Take China and Taiwan.
-
16:44 - 16:48In the 1990s, this was everyone's
leading World War III scenario. -
16:48 - 16:50But since that time,
-
16:50 - 16:54the trade and investment volumes
across the straits have become so intense -
16:54 - 16:55that last November,
-
16:55 - 16:58leaders from both sides
held a historic summit -
16:58 - 17:01to discuss eventual
peaceful reunification. -
17:02 - 17:05And even the election
of a nationalist party in Taiwan -
17:05 - 17:08that's pro-independence earlier this year
-
17:08 - 17:10does not undermine
this fundamental dynamic. -
17:11 - 17:14China and Japan have
an even longer history of rivalry -
17:14 - 17:17and have been deploying
their air forces and navies -
17:17 - 17:19to show their strength in island disputes.
-
17:20 - 17:21But in recent years,
-
17:21 - 17:25Japan has been making
its largest foreign investments in China. -
17:25 - 17:28Japanese cars are selling
in record numbers there. -
17:28 - 17:31And guess where
the largest number of foreigners -
17:31 - 17:34residing in Japan today comes from?
-
17:34 - 17:36You guessed it: China.
-
17:38 - 17:39China and India have fought a major war
-
17:39 - 17:41and have three outstanding
border disputes, -
17:42 - 17:44but today India is the second
largest shareholder -
17:44 - 17:46in the Asian Infrastructure
Investment Bank. -
17:46 - 17:50They're building a trade corridor
stretching from Northeast India -
17:50 - 17:54through Myanmar and Bangladesh
to Southern China. -
17:54 - 17:58Their trade volume has grown
from 20 billion dollars a decade ago -
17:58 - 18:00to 80 billion dollars today.
-
18:01 - 18:04Nuclear-armed India and Pakistan
have fought three wars -
18:04 - 18:06and continue to dispute Kashmir,
-
18:06 - 18:09but they're also negotiating
a most-favored-nation trade agreement -
18:09 - 18:11and want to complete a pipeline
-
18:11 - 18:15stretching from Iran
through Pakistan to India. -
18:15 - 18:17And let's talk about Iran.
-
18:18 - 18:21Wasn't it just two years ago
that war with Iran seemed inevitable? -
18:22 - 18:26Then why is every single major power
rushing to do business there today? -
18:29 - 18:30Ladies and gentlemen,
-
18:30 - 18:34I cannot guarantee
that World War III will not break out. -
18:35 - 18:38But we can definitely see
why it hasn't happened yet. -
18:39 - 18:42Even though Asia is home
to the world's fastest growing militaries, -
18:42 - 18:46these same countries
are also investing billions of dollars -
18:46 - 18:49in each other's infrastructure
and supply chains. -
18:49 - 18:53They are more interested
in each other's functional geography -
18:53 - 18:55than in their political geography.
-
18:55 - 19:00And that is why their leaders think twice,
step back from the brink, -
19:00 - 19:05and decide to focus on economic ties
over territorial tensions. -
19:06 - 19:09So often it seems
like the world is falling apart, -
19:10 - 19:12but building more connectivity
-
19:12 - 19:15is how we put Humpty Dumpty
back together again, -
19:15 - 19:17much better than before.
-
19:18 - 19:19And by wrapping the world
-
19:19 - 19:23in such seamless physical
and digital connectivity, -
19:23 - 19:25we evolve towards a world
-
19:25 - 19:28in which people can rise
above their geographic constraints. -
19:29 - 19:32We are the cells and vessels
-
19:32 - 19:35pulsing through these global
connectivity networks. -
19:35 - 19:39Everyday, hundreds of millions
of people go online -
19:39 - 19:42and work with people they've never met.
-
19:42 - 19:45More than one billion people
cross borders every year, -
19:45 - 19:49and that's expected to rise
to three billion in the coming decade. -
19:50 - 19:53We don't just build connectivity,
-
19:53 - 19:54we embody it.
-
19:55 - 19:58We are the global network civilization,
-
19:58 - 20:00and this is our map.
-
20:01 - 20:06A map of the world in which
geography is no longer destiny. -
20:07 - 20:11Instead, the future
has a new and more hopeful motto: -
20:11 - 20:13connectivity is destiny.
-
20:14 - 20:15Thank you.

20:15 - 20:22(Applause)
- Title:
- How megacities are changing the map of the world
- Speaker:
- Parag Khanna
- Description:
-
"I want you to reimagine how life is organized on earth," says global strategist Parag Khanna. As our expanding cities grow ever more connected through transportation, energy and communications networks, we evolve from geography to what he calls "connectography." This emerging global network civilization holds the promise of reducing pollution and inequality -- and even overcoming geopolitical rivalries. He asks us to embrace a new maxim for the future: “Connectivity is destiny.”
