The biggest risks facing cities and some solutions Robert Muggah

So, here’s a prediction.

If we get our cities right,

we just might survive the 21st century.

We get them wrong,

and we’re done for.

Cities are the most extraordinary
experiment in social engineering

that we humans have ever come up with.

If you live in a city,

and even if you live in a slum –

which 20 percent of the world’s
urban population does –

you’re likely to be healthier,
wealthier, better educated

and live longer than your country cousins.

There’s a reason why three million people
are moving to cities

every single week.

Cities are where the future happens first.

They’re open, they’re creative,
they’re dynamic, they’re democratic,

they’re cosmopolitan,

they’re sexy.

They’re the perfect antidote
to reactionary nationalism.

But cities have a dark side.

They take up just three percent
of the world’s surface area,

but they account for more than 75 percent
of our energy consumption,

and they emit 80 percent
of our greenhouse gases.

There are hundreds of thousands
of people who die in our cities

every single year from violence,

and millions more who are killed
as a result of car accidents

and pollution.

In Brazil, where I live,

we’ve got 25 of the 50 most homicidal
cities on the planet.

And a quarter of our cities
have chronic water shortages –

and this, in a country with 20 percent
of the known water reserves.

So cities are dual-edged.

Part of the problem is that,

apart from a handful of megacities
in the West and the Far East,

we don’t know that much
about the thousands of cities

in Africa, in Latin America, in Asia,

where 90 percent of all future
population growth is set to take place.

So why this knowledge gap?

Well, part of the problem

is that we still see the world
through the lens of nation-states.

We’re still locked
in a 17th-century paradigm

of parochial national sovereignty.

And yet, in the 1600’s,

when nation-states were really
coming into their own,

less than one percent
of the world’s population

resided in a city.

Today, it’s 54 percent.

And by 2050, it will be
closer to 70 percent.

So the world has changed.

We have these 193 nation-states,

but we have easily as many cities
that are beginning to rival them

in power and influence.

Just look at New York.

The Big Apple has 8.5 million people

and an annual budget
of 80 billion dollars.

Its GDP is 1.5 trillion,

which puts it higher
than Argentina and Australia,

Nigeria and South Africa.

Its roughly 40,000 police officers

means it has one of the largest
police departments in the world,

rivaling all but
the largest nation-states.

But cities like New York

or São Paulo

or Johannesburg

or Dhaka

or Shanghai –

they’re punching above
their weight economically,

but below their weight politically.

And that’s going to have to change.

Cities are going to have to find
their political voice

if we want to change things.

Now, I want to talk to you
a little bit about the risks

that cities are facing –

some of the big mega-risks.

I’m also going to talk to you briefly
about some of the solutions.

I’m going to do this
using a big data visualization

that was developed with Carnegie Mellon’s
CREATE Lab and my institute,

along with many, many others.

I want you to first imagine the world
not as made up of nation-states,

but as made up of cities.

What you see here is every single city

with a population
of a quarter million people or more.

Now, without going into technical detail,

the redder the circle,
the more fragile that city is,

and the bluer the circle,
the more resilient.

Fragility occurs when
the social contract comes unstuck.

And what we tend to see is a convergence
of multiple kinds of risks:

income inequality,

poverty,

youth unemployment,

different issues around violence,

even exposure to droughts,
cyclones and earthquakes.

Now obviously, some cities
are more fragile than others.

The good news, if there is any,

is that fragility is not
a permanent condition.

Some cities that were once the most
fragile cities in the world,

like Bogotá in Colombia

or Ciudad Juárez in Mexico,

have now fallen more
around the national average.

The bad news is
that fragility is deepening,

especially in those parts of the world
that are most vulnerable,

in North Africa, the Middle East,

in South Asia and Central Asia.

There, we’re seeing fragility rising
way beyond scales we’ve ever seen before.

When cities become too fragile
they can collapse,

tip over and fail.

And when that happens,

we have explosive forms of migration:

refugees.

There are more than 22 million
refugees in the world today,

more than at any other time
since the second world war.

Now, there’s not one refugee crisis;

there are multiple refugee crises.

And contrary to what
you might read in the news,

the vast majority of refugees
aren’t fleeing from poor countries

to wealthy countries,

they’re moving from poor cities
into even poorer cities –

often, cities nearby.

Every single dot on this map
represents an agonizing story

of struggle and survival.

But I want to briefly tell you
about what’s not on that map,

and that’s internal displacement.

There are more than 36 million people
who have been internally displaced

around the world.

These are people living
in refugee-like conditions,

but lacking the equivalent international
protection and assistance.

And to understand their plight,

I want to zoom in briefly on Syria.

Syria suffered one of the worst droughts
in its history between 2007 and 2010.

More than 75 percent of its agriculture
and 85 percent of its livestock

were wiped out.

And in the process,
over a million people moved into cities

like Aleppo, Damascus and Homs.

As food prices began to rise,

you also had equivalent levels
of social unrest.

And when the regime of President Assad
began cracking down,

you had an explosion of refugees.

You also had over six million
internally displaced people,

many of whom when on to become refugees.

And they didn’t just move
to neighboring countries like Jordan

or Lebanon or Turkey.

They also moved up north
towards Western Europe.

See, over 1.4 million Syrians
made the perilous journey

through the Mediterranean
and up through Turkey

to find their way
into two countries, primarily:

Germany and Sweden.

Now, climate change –

not just drought, but also sea level rise,

is probably one of the most severe
existential threats

that cities face.

That’s because two-thirds
of the world’s cities are coastal.

Over 1.5 billion people live in low-lying,
flood-prone coastal areas.

What you see here is a map
that shows sea level rise

in relation to changes in temperature.

Climate scientists predict
that we’re going to see

anywhere between three
and 30 feet of sea level rise

this side of the century.

And it’s not just low island nation-states
that are going to suffer –

Kiribati or the Maldives
or the Solomons or Sri Lanka –

and they will suffer,

but also massive cities like Dhaka,

like Hong Kong,

like Shanghai.

Cities of 10, 20, 30 million
people or more

are literally going to be wiped off
the face of this earth.

They’re going to have to adapt,
or they’re going to die.

I want to take you also
all the way over to the West,

because this isn’t just a problem
in Asia or Africa or Latin America,

this is a problem also in the West.

This is Miami.

Many of you know Miami
is one of the wealthiest cities

in the United States;

it’s also one of the most flood-prone.

That’s been made painfully evident
by natural disasters throughout 2017.

But Miami is built
on porous limestone – a swamp.

There’s no way any kind of flood barrier

is going to keep
the water from seeping in.

As we scroll back,

and we look across the Caribbean
and along the Gulf,

we begin to realize

that those cities that have suffered
worst from natural crises –

Port-au-Prince, New Orleans, Houston –

as severe and as awful
as those situations have been,

they’re a dress rehearsal
for what’s to come.

No city is an island.

Every city is connected
to its rural hinterland

in complex ways –

often, in relation
to the production of food.

I want to take you to the northern part
of the Amazon, in Rondônia.

This is one of the world’s largest
terrestrial carbon sinks,

processing millions of carbon
every single year.

What you see here is a single road
over a 30-year period.

On either side you see land being
cleared for pasture, for cattle,

but also for soy and sugar production.

You’re seeing deforestation
on a massive scale.

The red area here implies a net loss
of forest over the last 14 years.

The blue, if you could see it –
there’s not much –

implies there’s been an incremental gain.

Now, as grim and gloomy
as the situation is – and it is –

there is a little bit of hope.

See, the Brazilian government,

from the national to the state
to the municipal level,

has also introduced a whole range –
a lattice – of parks and protected areas.

And while not perfect,
and not always limiting encroachment,

they have served
to tamp back deforestation.

The same applies not just in Brazil
but all across the Americas,

into the United States, Canada
and around the world.

So let’s talk about solutions.

Despite climate denial
at the highest levels,

cities are taking action.

You know, when the US pulled out
of the Paris Climate Agreement,

hundreds of cities in the United States
and thousands more around the world

doubled down on their climate commitments.

(Applause)

And when the White House cracked down
on so-called “undocumented migrants”

in sanctuary cities,

hundreds of cities and counties
and states sat up in defiance

and refused to enact that order.

(Applause)

So cities are and can take action.

But we’re going to need
to see a lot more of it,

especially in the global south.

You see, parts of Africa
and Latin America are urbanizing

before they industrialize.

They’re growing at three times
the global average

in terms their population.

And this is putting enormous strain
on infrastructure and services.

Now, there is a golden opportunity.

It’s a small opportunity but a golden one:
in the next 10 to 20 years,

to really start designing in
principles of resilience into our cities.

There’s not one single way of doing this,

but there are a number of ways
that are emerging.

And I’ve spoken with hundreds
of urban planners,

development specialists,

architects and civic activists,

and a number of recurring
principles keep coming out.

I just want to pass on six.

First: cities need a plan

and a strategy to implement it.

I mean, it sounds crazy,

but the vast majority of world cities
don’t actually have a plan

or a vision.

They’re too busy putting out daily fires
to think ahead strategically.

I mean, every city wants to be creative,

happy, liveable, resilient –

who doesn’t?

The challenge is, how do you get there?

And urban governance plays a key role.

You could do worse than take a page
from the book of Singapore.

In 1971, Singapore set
a 50-year urban strategy

and renews it every five years.

What Singapore teaches us
is not just the importance of continuity,

but also the critical role
of autonomy and discretion.

Cities need the power
to be able to issue debt,

to raise taxes,

to zone effectively,

to build affordable housing.

What cities need is nothing less
than a devolution revolution,

and this is going to require
renegotiating the terms of the contract

with a nation-state.

Second:

you’ve got to go green.

Cities are already leading
global decarbonization efforts.

They’re investing in congestion
pricing schemes,

in climate reduction emission targets,

in biodiversity, in parks
and bikeways and walkways

and everything in between.

There’s an extraordinary menu of options
they have to choose from.

One of the great things is,

cities are already investing heavily
in renewables – in solar and wind –

not just in North America, but especially
in Western Europe and parts of Asia.

There are more than 8,000 cities
right now in the world today

with solar plants.

There are 300 cities that have declared
complete energy autonomy.

One of my favorite stories
comes from Medellín,

which invested in a municipal
hydroelectric plant,

which doesn’t only service
its local needs,

but allows the city to sell excess energy
back onto the national grid.

And it’s not alone.

There are a thousand
other cities just like it.

Third: invest in integrated
and multi-use solutions.

The most successful cities are those
that are going to invest in solutions

that don’t solve just one problem,
but that solve multiple problems.

Take the case of integrated
public transport.

When done well –

rapid bus transit,

light rail,

bikeways, walkways, boatways –

these can dramatically reduce
emissions and congestion.

But they can do a lot more than that.

They can improve public health.

They can reduce dispersion.

They can even increase safety.

A great example of this comes from Seoul.

You see, Seoul’s population doubled
over the last 30 years,

but the footprint barely changed.

How?

Well, 75 percent
of Seoul’s residents get to work

using what’s been described as

one of the most extraordinary
public transport systems

in the world.

And Seoul used to be car country.

Next, fourth:

build densely but also sustainably.

The death of all cities is the sprawl.

Cities need to know
how to build resiliently,

but also in a way that’s inclusive.

This is a picture right here
of Dallas-Fort Worth.

And what you see is its population
also doubled over the last 30 years.

But as you can see, it spread
into edge cities and suburbia

as far as the eye can see.

Cities need to know when not to build,

so as not to reproduce urban sprawl

and slums of downward accountability.

The problem with Dallas-Forth Worth is

just five percent of its residents get
to work using public transport – five.

Ninety-five percent use cars,

which partly explains why it’s got
some of the longest commuting times

in North America.

Singapore, by contrast, got it right.

They built vertically

and built in affordable housing to boot.

Fifth: steal.

The smartest cities are nicking,
pilfering, stealing,

left, right and center.

They don’t have time to waste.

They need tomorrow’s technology today,

and they’re going
to leapfrog to get there.

This is New York,

but it’s not just New York
that’s doing a lot of stealing,

it’s Singapore, it’s Seoul, it’s Medellín.

The urban renaissance
is only going to be enabled

when cities start borrowing
from one another.

And finally: work in global coalitions.

You know, there are more than 200
inner-city coalitions in the world today.

There are more city coalitions

than there are coalitions
for nation-states.

Just take a look at the Global
Parliament of Mayors,

set up by the late Ben Barber,

who was driving an urban rights movement.

Or consider the C40,

a marvelous network of cities
that has gathered thousands together

to deliver clean energy.

Or look at the World Economic Forum,

which is developing smart city protocols.

Or the 100 Resilient Cities initiative,

which is leading a resilience revival.

ICLEI, UCLG, Metropolis –

these are the movements of the future.

What they all realize
is that when cities work together,

they can amplify their voice,

not just on the national stage,
but on the global stage.

And with a voice comes,
potentially, a vote –

and then maybe even a veto.

When nation-states default
on their national sovereignty,

cities have to step up.

They can’t wait.

And they don’t need to ask for permission.

They can exert their own sovereignty.

They understand
that the local and the global

have really, truly come together,

that we live in a global, local world,

and we need to adjust
our politics accordingly.

As I travel around the world
and meet mayors and civic leaders,

I’m amazed by the energy,
enthusiasm and effectiveness

they bring to their work.

They’re pragmatists.

They’re problem-solvers.

They’re para-diplomats.

And in this moment of extraordinary
international uncertainty,

when our multilateral
institutions are paralyzed

and our nation-states are in retreat,

cities and their leaders are our new
21st-century visionaries.

They deserve – no, they have
a right to – a seat at the table.

Thank you.

(Applause)

所以,这里有一个预测。

如果我们让我们的城市正确,

我们可能会在 21 世纪幸存下来。

我们弄错了

,我们就完了。

城市是

我们人类提出的社会工程中最非凡的实验。

如果你住在城市

,即使你住在贫民窟——

世界上 20% 的
城市人口就是这样——

你很可能比你的乡下人更健康、更
富有、受过更好的教育

并且活得更久。 每周

有 300 万人搬到城市是有原因的

城市是未来首先发生的地方。

他们是开放的,他们是有创造力的,
他们是充满活力的,他们是民主的,

他们是国际化的,

他们是性感的。

它们是
反动民族主义的完美解毒剂。

但城市也有阴暗面。

它们仅占
世界表面积的 3%,


占我们能源消耗的 75% 以上

,排放了 80%
的温室气体。

在我们的城市中,

每年有数十万人死于暴力,

还有数百万人
死于车祸

和污染。

在我居住的巴西,

我们拥有地球上 50 个杀人最多的
城市中的 25 个。

我们四分之一的
城市长期缺水——

而在这个拥有
已知水资源储量 20% 的国家。

所以城市是双刃剑。

部分问题在于,

除了西部和远东的少数特大城市之外

我们

对非洲、拉丁美洲和亚洲的数千个城市知之甚少,这些城市

未来人口的 90%
增长势在必行。

那么为什么会出现这种知识鸿沟呢?

好吧,部分问题

在于我们仍然
通过民族国家的视角看待世界。

我们仍然停留
在 17 世纪

狭隘的国家主权范式中。

然而,在 1600 年代,

当民族国家
真正形成自己的国家时,

只有不到 1%
的世界人口

居住在城市中。

今天,它是 54%。

到 2050 年,这一
比例将接近 70%。

所以世界变了。

我们有这 193 个民族国家,

但我们也有许多
城市开始

在权力和影响力上与它们抗衡。

看看纽约。

大苹果有 850 万人口

,每年的预算
为 800 亿美元。

其GDP为1.5万亿,

高于阿根廷、澳大利亚、

尼日利亚和南非。

它的大约 40,000 名警察

意味着它拥有世界上最大的
警察部门之一,可以


除最大的民族国家之外的所有国家相媲美。

但是像纽约

、圣保罗

、约翰内斯堡

、达卡

或上海这样的城市——

他们在
经济上的表现超出了他们的体重,

但在政治上却低于他们的体重。

这将不得不改变。 如果我们想改变

现状,城市将不得不找到
他们的政治声音

现在,我想和你谈谈

城市面临的风险——

一些巨大的风险。

我还将与您简要
讨论一些解决方案。

我将
使用

与卡内基梅隆大学的
CREATE 实验室和我的研究所

以及许多其他人一起开发的大数据可视化来做到这一点。

我希望你首先想象世界
不是由民族国家组成,

而是由城市组成。

你在这里看到的是每一个

拥有 25 万或更多人口的城市。

现在,不涉及技术细节,

圆圈越红
,城市越脆弱

,圆圈越蓝,
弹性越大。

当社会契约破裂时,就会出现脆弱性。

我们往往会看到
多种风险的融合:

收入不平等、

贫困、

青年失业、

围绕暴力的不同问题,

甚至是干旱、
飓风和地震。

现在很明显,有些城市
比其他城市更脆弱。

好消息(如果有的话)

是脆弱性
不是永久性的。

一些曾经
是世界上最脆弱的城市,

如哥伦比亚的波哥大

或墨西哥的华雷斯城

,现在的跌幅已
接近全国平均水平。

坏消息
是脆弱性正在加深,

尤其是在世界
上最脆弱的

地区,如北非、中东

、南亚和中亚。

在那里,我们看到脆弱性
以前所未有的规模上升。

当城市变得过于脆弱时,
它们可能会倒塌、

倾覆和倒塌。

当这种情况发生时,

我们就会出现爆炸性的移民形式:

难民。 当今世界上

有超过 2200 万
难民,

比二战以来的任何时候都多

现在,没有一场难民危机。

存在多起难民危机。


你在新闻中看到的相反

,绝大多数
难民不是从贫穷国家

逃到富裕国家,

而是从贫穷城市
转移到更贫穷的城市——

通常是附近的城市。

这张地图上的每一个点都
代表着一个

关于斗争和生存的痛苦故事。

但我想简单地告诉你
什么不在这张地图上

,那就是内部流离失所。

全世界有超过 3600
万人在国内流离失所

这些人生活
在类似难民的环境中,

但缺乏同等的国际
保护和援助。

为了了解他们的困境,

我想简要介绍一下叙利亚。

叙利亚
在 2007 年至 2010 年期间遭受了历史上最严重的干旱之一。

超过 75% 的农业
和 85% 的牲畜

被摧毁。

在此过程中,
超过 100 万人迁入

阿勒颇、大马士革和霍姆斯等城市。

随着食品价格开始上涨,

您也遇到了同等程度
的社会动荡。

当阿萨德总统的政权
开始镇压时,

难民人数激增。

你们还有超过 600 万
国内流离失所者,

其中许多人后来成为难民。

他们不只是
搬到约旦

、黎巴嫩或土耳其等邻国。

他们也向北移动
到西欧。

看,超过 140 万叙利亚人

经过地中海
和土耳其

的危险旅程,找到了
进入两个国家的路,主要是:

德国和瑞典。

现在,气候变化——

不仅仅是干旱,还有海平面上升

,可能是城市面临的最严重的
生存威胁

之一。

那是因为
世界上三分之二的城市是沿海城市。

超过 15 亿人生活在低洼、
洪水多发的沿海地区。

你在这里看到的是一张地图
,它显示了海平面上升

与温度变化的关系。

气候科学家预测
,在本世纪这一边,我们将看到

海平面上升 3
到 30 英尺

不仅低岛民族
国家会受苦——

基里巴斯、马尔代夫
、所罗门群岛或斯里兰卡

——它们会受苦,

而且像达卡、

香港、上海这样的大城市也会受苦

拥有 10、20、3000
万或更多人口

的城市实际上将在
地球上消失。

他们将不得不适应,
否则他们将死去。

我也想带你们
一路走到西方,

因为这不仅仅是
亚洲、非洲或拉丁美洲

的问题,这也是西方的问题。

这是迈阿密。

你们中的许多人都知道迈阿密
是美国最富有的城市

之一。

它也是最容易发生洪水的地方之一。

整个 2017 年的自然灾害使这一点非常明显。

但迈阿密是建立
在多孔石灰岩上的——一片沼泽。

任何形式的防洪屏障

都无法
阻止水渗入。

当我们向后滚动时

,我们会看到加勒比海
和海湾沿岸,

我们开始

意识到那些
遭受自然危机最严重的城市——

太子港、新奥尔良、休斯顿

——尽管
这些情况非常严重和可怕,

但它们是
对即将发生的事情的彩排。

没有一座城市是一座孤岛。

每个城市都
以复杂的方式与其农村腹地相连

——

通常
与食品生产有关。

我想带你去
亚马逊北部的朗多尼亚。

这是世界上最大的
陆地碳汇之一,每年

处理数百万碳

你在这里看到的是一条
跨越 30 年的单一道路。

在两边,你看到土地被
清理用于放牧、养牛,

还有大豆和糖生产。

你正在看到
大规模的森林砍伐。

这里的红色区域表示
过去 14 年森林的净损失。

蓝色,如果你能看到它——
没有太多——

意味着有一个增量收益。

现在,尽管
形势严峻——而且确实如此——

但还是有一点希望。

看,巴西政府,

从国家级到州
级,再到市级,

还引入了一个完整的范围——
一个网格——公园和保护区。

虽然并不完美
,也不总是限制侵占,

但它们已经起到
了遏制森林砍伐的作用。

这不仅适用于巴西,也适用于
整个美洲

,包括美国、加拿大
和世界各地。

所以让我们谈谈解决方案。

尽管
最高层否认气候变化,但

城市正在采取行动。

你知道,当美国退出
《巴黎气候协定》时,

美国数百个城市
以及全球数千个城市

加倍履行其气候承诺。

(掌声

)当白宫在庇护城市
镇压所谓的“无证移民”

时,

数百个市县
和州坐视不理

,拒绝颁布该命令。

(掌声)

所以城市正在并且可以采取行动。

但我们
需要看到更多,

尤其是在全球南部。

你看,非洲
和拉丁美洲的部分地区

在工业化之前正在城市化。

就人口而言,它们的增长速度
是全球平均水平的三倍

这给
基础设施和服务带来了巨大压力。

现在,有一个千载难逢的机会。

这是一个很小的机会,但却是一个黄金机会:
在接下来的 10 到 20 年内

,真正开始
按照弹性原则设计我们的城市。

没有一种方法可以做到这一点,

但有很多
方法正在出现。

我已经与数百
名城市规划师、

发展专家、

建筑师和公民活动家进行了交谈

,许多反复出现的
原则不断涌现。

我只想传递六个。

第一:城市需要一个计划

和战略来实施它。

我的意思是,这听起来很疯狂,

但绝大多数世界城市
实际上并没有计划

或愿景。

他们忙于扑灭日常的火灾,
无法进行战略性思考。

我的意思是,每个城市都想变得富有创造力、

快乐、宜居、有弹性——

谁不呢?

挑战是,你如何到达那里?

城市治理起着关键作用。

你可以做得比从新加坡的书中翻页更糟糕

1971年,新加坡制定
了50年城市战略

,每五年更新一次。

新加坡教给我们
的不仅仅是连续性的重要性,

还有
自主权和自由裁量权的关键作用。

城市
需要有能力发行债务

、提高税收、

有效分区

、建造经济适用房。

城市需要的无非是
一场权力下放革命,

而这将需要

与一个民族国家重新谈判合同条款。

第二:

你必须走向绿色。

城市已经在引领
全球脱碳努力。

他们正在投资拥堵
定价计划

、气候减排目标、

生物多样性、公园
、自行车道和人行道

以及介于两者之间的一切。

他们必须从中选择一个非凡的选项菜单

一件好事是,

城市已经在大力
投资可再生能源——太阳能和风能——

不仅在北美,尤其是
在西欧和亚洲部分地区。

当今世界上

有 8,000 多个城市拥有太阳能发电厂。

有 300 个城市已宣布
完全能源自治。

我最喜欢的故事之一
来自麦德林,

它投资了一座市政
水力发电厂

,不仅
满足当地的需求,

还允许该市将多余的能源卖
回国家电网。

它并不孤单。

还有一千个
其他城市就像它一样。

第三:投资于综合
和多用途解决方案。

最成功的城市是
那些将投资于

不仅解决一个问题,
而且解决多个问题的解决方案的城市。

以综合
公共交通为例。

如果做得好——

快速公交、

轻轨、

自行车道、人行道、船道——

这些可以显着减少
排放和拥堵。

但他们可以做的远不止这些。

他们可以改善公共卫生。

它们可以减少分散。

它们甚至可以提高安全性。

首尔就是一个很好的例子。

你看,首尔的人口
在过去 30 年中翻了一番,

但足迹几乎没有变化。

如何?

嗯,
首尔 75% 的居民

使用被称为

世界上最非凡的
公共交通

系统之一上班。

首尔曾经是汽车之乡。

其次,第四:

密集但可持续地建设。

所有城市的死亡都是蔓延。

城市需要知道
如何以

一种具有包容性的方式进行弹性建设。


是达拉斯-沃思堡的照片。

你看到的是它的人口
在过去 30 年里也翻了一番。

但正如你所见,它蔓延
到尽头的边缘城市和郊区

城市需要知道什么时候不建,

以免重复城市蔓延

和向下问责的贫民窟。

Dallas-Forth Worth 的问题是

只有 5% 的居民
使用公共交通工具上班——5%。

95% 的人使用汽车,

这部分解释了为什么它的
通勤时间在北美是最长的

相比之下,新加坡做对了。

他们垂直建造

并建造了经济适用房。

第五:偷窃。

最聪明的城市是偷窃、
偷窃、偷窃、

左、右和中心。

他们没有时间可以浪费。

他们今天需要明天的技术,

而且他们
将跨越式地到达那里。

这是纽约,

但不只是纽约
在做很多偷窃,

它是新加坡,它是首尔,它是麦德林。

只有

当城市开始相互借贷时,城市复兴才会启动

最后:在全球联盟中工作。

要知道,
当今世界上有 200 多个内城联盟。

城市联盟

比民族国家联盟多。

看看

由已故的 Ben Barber 建立的全球市长议会,

他正在推动一场城市权利运动。

或者考虑一下 C40,

一个奇妙的城市网络
,将数千人聚集

在一起提供清洁能源。

或者看看

正在开发智能城市协议的世界经济论坛。

或者 100 弹性城市倡议,

它正在引领弹性复兴。

ICLEI、UCLG、Metropolis——

这些都是未来的运动。

他们都
意识到,当城市合作时,

他们可以扩大自己的声音,

不仅在国家舞台上,
而且在全球舞台上。

伴随着声音而来的,
可能是投票——

甚至可能是否决权。

当民族国家
违背其国家主权时,

城市就必须挺身而出。

他们等不及了。

他们不需要征求许可。

他们可以行使自己的主权。

他们
明白本地和全球

已经真正、真正地走到了一起

,我们生活在一个全球化的本地世界中

,我们需要相应地调整
我们的政治。

当我环游世界
并会见市长和公民领袖时,

我对他们为工作带来的活力、
热情和效率感到惊讶

他们是实用主义者。

他们是问题解决者。

他们是副外交官。

在这个充满
国际不确定性的时刻,

当我们的多边
机构陷入瘫痪

,我们的民族国家在退却时,

城市及其领导人是我们
21 世纪的新梦想家。

他们应该——不,他们
有权——在餐桌上占有一席之地。

谢谢你。
