Today, 54 per cent of the world’s population lives in cities. By 2050, this proportion will increase to around 67 percent and add more than 2.5 billion people.
96 percent of all urbanization by 2030 will occur in the developing world.
Is the world's urban population going to be situated in mega cities?
Or in smaller ones?
Let's find out using the latest data from United Nations Population Department.
A sample of 10 countries — some of them the most populous in the world — shows that most urbanites are going to live in bigger urban cities by 2030.
Some countries have a high proportion of their population living in extremely big cities. Japan, for example, which has megacity Tokyo.
Do you know what are the biggest cities in the world in 2015?
If you guessed most of the biggest cities are in Asia you'll be right.
For all the benefits that urbanization brings like literacy and better standards of living, it also brings challenges.
Sustainable urbanization is going to be a very real problem for billions. This, together with issues like global warming, are some of the biggest challenge humans will ever face.
Traffic.
Energy.
Food.
Flooding and landslides.
Water.
Pollution.
I would like to end this journey by introducing a brilliant thought provoking documentary entitled Under the Dome that everybody should watch. (No I'm not affiliated with Chai Jing in any way.)
