Entrepreneur Marc Lore has revealed plans to create a new megacity in a desert in the United States.
Known as Telosa City, residents could expect 15-minute commutes and farms built on skyscrapers. The name comes from the Greek word used by Aristotle, the Greek philosopher, scientist, and polymath who lived from 384 to 322 BCE, and means "highest goal".
The cost to build it would be around £320 billion ($400bn).
Mr Lore reportedly says he wants Telosa to be as eco-friendly as a Scandinavian city but as free as somewhere in the USA.
Cars using fossil fuels would be banned, with public transport, bicycles, and autonomous vehicles taking their place. The proposed city’s website says the developers want Telosa to be "open", "fair", and "inclusive". Equality is also set to have a huge emphasis.
Meanwhile, Neom, a futuristic megacity in Saudi Arabia, has announced its latest development. It is being created to diversify Saudi Arabia's economy from oil dependence.
Megacities have the potential to reduce poverty by offering economic opportunities and resources.
So how are megacities defined and where are they in the world?
What is a megacity?
A megacity is defined as an urban area typically with a population of more than 10 million people. In 1975, there were only four megacities — New York, Tokyo, Mexico City, and São Paolo. Now, there are an estimated 47 megacities all over the world.
Is London a megacity?
Yes, London has megacity status as shown by its population mentioned below.
Where are the world’s megacities?
The exact number of megacities depends on the defining criteria used by different organisations. Here's a breakdown:
- UN: 33 (as of 2018)
- CityPopulation.de: 45 (as of 2023)
- Demographia: 44 (as of 2023)
These figures suggest there are somewhere between 33 and 45 megacities globally. Here’s the list of 44 megacities from Demographia.
