Why Many Big Cities are Sinking?

Friday, August 30, 2019
Jakarta, Indonesian capital

Many big cities which have roles as business centers, historical tourist destinations and capitals faced what we call as “sinking cities.”

The cities are spreading from industry to developing countries, they are:
- capitals (Jakarta – Indonesia, Lagos – Nigeria, Washington – USA, and Beijing - China)
- historical city (Venice – Italy)
- business centers (Houston – Texas, Long Beach – California).

The sinking rate is astonishing, from 0.4 inches (1 cm) to 10 inches (25 cm) per year.

Jakarta have been sinking for 4 meter (12 feet) since 1970. The rate of sinking could reach at speed of 10 inches (25 cm) per year on some parts of city. The highest in the world.

The sinking leads to damages of sewage and drain systems, thus, vulnerable to flood. Then, flooding is endemic in every even drizzle (small rains).

The questions then:
- what caused sinking?
- how to prevent sinking further? 



Long Beach, California

The main factor to cause sinking is over using of groundwater. Include exploiting of oil and gas in close by regions in several cities.

There are several ways to stop subsidence:
- Limit or stop groundwater exploiting
- Injecting water into deep underground 


Venice, Italy

Tokyo, Japan formulated the law to halt the sinking by limiting to pump groundwater. This effort was success story where the sinking rate of 9 inches (24 cm) per year reduced to 0.4 inches (1 cm) per year.

Injecting technique has been done by Long Beach, California. After sinking by 30 feet (10 m) for decades, injecting has stabilized the surface dropping.

In addition, surface elevation up to 30 cm was seen in several areas of Long Beach.


Finally, combinations of program to groundwater reducing and injecting have been success to halt further sinking in Venice, Italy.

  3. The water level is rising year by year and will get worse if we are not aware of global warming.
