Indonesia's $30 billion purpose-built new capital city is not going to plan

• Indonesia is building a new capital city from scratch to deal with rising sea levels.
• The new city, Nusantara, was set to be operational in October. But things are not going according to plan.
• The estimated $30 billion megaproject is struggling with funding issues and construction delays.

Jakarta, the current capital of Indonesia, is overpopulated and sinking.

Southeast Asia's largest megacity is home to some 10.6 million people. But with 40% of the wider metropolitan area below sea level, the effects of climate change are increasingly causing flooding across the capital.

So, in 2019, Indonesia's government approved an ambitious plan to build a new capital city 100 miles away from Jakarta.
