Jakarta is home to more than ten million residents. The metropolitan area is more than three times bigger.
The city is on track to surpass Tokyo as the world's largest megacity by 2030.
Jakarta currently rests on swampy land in a low-lying basin along the Java Sea.
Nearly half of the city sits below sea level, making it extremely vulnerable to floods.

This excessive groundwater pumping has turned Jakarta into the world's fastest-sinking city.
As the land dips lower, sea levels have gotten higher due to climate change.
The devastating combination of floods and subsidence threatens to submerge entire swathes of the city by 2050.
To combat this issue, Jakarta's president, Joko Widodo, has approved a plan to move the capital 100 miles away from its current location.

Before arriving at this plan, the city struggled to control an annual stream of floods.
One of the most destructive floods took place in 2007. Around 70,000 homes were submerged and around 80 people died.
In 2013, another flood killed nearly 50 people. The damage was made worse by the city's poor sewage system, which is often clogged with garbage and debris.
A year later, Jakarta decided to build a giant, 15-mile sea wall to protect the city from flooding.

The issue of flooding in Jakarta is often tied up with the city's inequality.
When wealthy communities pump groundwater, they cause subsidence in low-lying coastal areas.
These areas are often occupied by residents who can't afford to live in the central business district or elite residential enclaves.
Moving the capital to a new location could eliminate some of the strain on Jakarta's resources, thereby reducing inequality.
