What do you know about
problems in Chinese cities?

3 main issues:

1. Smog / air pollution

2. Water shortages

3. Groundwater exhaustion

Which two sources are the most important for air pollution in China?

1. Factories and cars
2. Factories and coal-fired power stations
3. Cars and coal-fired power stations
4. People use it at home

Do we have issues with smog in the Netherlands? Why?

Where do you use water for?

Water shortages

North of China > Gobi desert

Huang He / Yellow River dries up

> Shortages in the densely populated delta

Water consumption has increased due to changes in the way of life 

and an expending population

Storage dams to control the water level. 

Disadvantage: a lot of evaporation

Groundwater / surface water

Aquifer = an underground water-bearing layer 

> Needed for agriculture

> Needed as drinking water

Groundwater level drops at least 1 m every year!

Amount pumped water is bigger than precipitation

 > water is not  used sustainable!

What could be a good solution for those water issues?

Wet in the south, dry in the north

Solution = water from the wet south to the dry north

> South-to-North Water Diversion Project

Expensive! > 50 billion

- Digging canals

- Building tunnels under rivers

Are there questions left?
