How will our future cities look?


Imagine a city of the future. Do you see clean streets, flying cars and robots doing all the work?
Or perhaps your vision is more dystopian, with a Big Brother-style authoritarian regime, dark alleys full of crime, and people forced to live in hermetically sealed pods because war or some other disaster has rendered whole swathes of the city unliveable.
No-one really knows what the future holds, but the reality now is that our urban spaces are overcrowded and polluted.
Almost half of the world's population currently lives in cities, and by 2050 that is projected to increase to 75%, but what kind of city will they be living in?
The time is ripe, say experts, to start designing smarter urban environments, both new cities needed to sustain an ever-growing population, and retro-fits on the ones that we have lived in for centuries.

Greenification

If the cities of the past were shaped by people, the cities of the future are likely to be shaped by ideas, and there are a lot of competing ones about how such a futuristic urban space should look.
Some of these revolve around the idea that smarter equals greener. Sustainability experts predict carbon-neutral cities full of electric vehicles and bike-sharing schemes, with air quality so much improved that office workers can actually open their windows for the first time.
Visions of a green city often include skyscrapers where living and office space vie with floating greenhouses or high-rise vegetable patches and green roofs, as we try to combine urbanisation with a return to our pastoral past.
Behind such greenification of cities lies a very pressing need.
