Alice: Hello and welcome to 6 Minute English. I'm Alice.
Neil: And I'm Neil.
Alice: Have you ever played SimCity, Neil? the city-building computer game.
Neil: Yes, but I wasn't very good at it.
I didn't build enough houses, which created a lot of homeless Sims
those are the characters in the game.
And then I didn't deal effectively with a flood.
Alice: Really? Well, I suppose managing a city is quite a challenge
which is the subject of today's show: cities of the future
an important subject as so many of us now live in urban areas.
I want to start with our quiz question:
What is the percentage of the world's population that will be living in cities in 2050?
We're dealing with approximates here. Is it... a) 10%?
b) 50%? Or c) 70%?
Neil: I think that it's a) 10%.
Alice: Well, we'll find out if you're right or wrong later on in the show.
Now, you've encountered a couple of issues that might face urban planners when designing a city, Neil
housing and dealing with a flood.
Can you think of any others?
Neil: Yes. Having decent cycle lanes. Good transport networks are very important.
Alice: Yes indeed, and if people could get around easily on foot, or by bike, or by public transport,
roads would be less congested – or overcrowded – and less polluted.
That sounds rather utopian to me though.
Neil: A utopia is an imaginary place where everything is perfect.
But Copenhagen is pretty utopian, Alice
the air is clean, there are bike lanes everywhere.
Alice: That sounds fantastic, but what about somewhere like Beijing with its constant smog
or air pollution hanging over the city?
A lot of people ride bikes there too. So which city is going to be the model for the future?
Neil: Maybe like the future Los Angeles in the movie Blade Runner
you know, glittering high-rises, gigantic neon billboards, flying cars...
Alice: Well, today's Los Angeles has terrible urban sprawl and traffic problems.
Neil: Urban sprawl is the way a city spreads into undeveloped land around it,
often without planning permission.
Alice: Dr Janice Pearlman can explain why this happens.
She is the founder and president of the Megacities Project non-profit organization in Rio de Janeiro
and knows a lot about urban sprawl in Brazilian cities.
Dr Janice Pearlman: People are coming massively into the cities which have no housing
that's affordable to them.
So they can't rent and they can't buy, and they end up building their own
communities and houses on unoccupied land.
And these communities are becoming in some places the majority not the minority
and they're off the grid so they're not often serviced by either the social services
but also many of them don't have water, sanitation and electricity.
Neil: People migrate – or move – from the countryside to the city to get better
opportunities, but end up with nowhere to live.
Alice: So they build their own housing on unoccupied land.
These shanty towns – poor communities where the houses are built out of cheap materials
like corrugated iron and plastic sheeting – are often off the grid...
Neil: Which means they don't have an electricity or water supply – or access to healthcare and education.
And these communities are growing, so the problem is getting bigger.
So are there any solutions, Alice?
Alice: Well, it's all about improving the infrastructure.
That's the basic facilities a town or city needs, for example: communication, transport, water, and electricity.
But this shouldn't only mean improving housing conditions, but also promoting education and
employment among the inhabitants, and building better communities.
Neil: That sounds like a real headache for the urban planners.
Alice: You're right there.
And one thing urban planners are talking about at the moment is creating 'smart cities'.
John Rossant, founder and chairman of the non-profit organisation New Cities Foundation, explains what it is.
John Rossant: I think, you know, generally it's accepted that cloud computing, ubiquitous internet,
robust 5G networks etc, will transform our cities,
whether they're in the global south or the developed world.
And, you know, technology is really a game changer, I think, in urbanisation.
Neil: John Rossant there. What's ubiquitous, Alice?
Alice: It means available everywhere.
So, the idea behind smart cities is to use technology to collect large amounts of data about how a city is performing.
Neil: And that will be a game changer – significantly affecting the way our cities function.
Hope for the future, Alice?
Alice: Fingers crossed.
Now, I think it's time for the answer to today's quiz question, Neil.
I asked: What is the percentage of the world's population that will be living in cities in 2050?
And remember I said we are dealing with approximates here? Is it... a) 10%? b) 50%? Or c) 70%?
Neil: And I said a) 10%.
Alice: Yes, and you underestimated there, Neil.
The right answer is actually c) 70%.
This, according to a report by the United Nations.
Today 54% of the world's population lives in urban areas.
Neil: A lot really!
Alice: Yeah.
Neil: Well, I know we're running out of time, so let me repeat the words we learned today.
They were:
congested
utopia
smog
urban sprawl
migrate
shanty towns
off the grid
infrastructure
ubiquitous
game changer
