Jakarta: World's Largest City Faces Sinking Crisis

The Greater Jakarta region, known as Jabodetabek, has become the world's most populous urban area, housing approximately 42 million people. This surpasses Tokyo's metropolitan population of around 33 million.

This vast urban sprawl, formed by the physical merging of cities like Bogor, Depok, Tangerang, and Bekasi, faces significant environmental and infrastructural hurdles. Parts of North Jakarta are currently subsiding at a rate of up to 25 cm annually, primarily caused by excessive groundwater extraction.

Traffic congestion is a persistent problem, ranking among the most severe globally and leading to substantial economic losses. Furthermore, the metropolitan area's infrastructure struggles to keep pace, with limited access to formal sewage systems contributing to pollution in its numerous rivers.

In light of these challenges and projected population growth to potentially 45-50 million by 2050, Indonesia is undertaking a major relocation of its official capital. The new city, Nusantara, is being purpose-built in East Kalimantan on the island of Borneo.

While government functions will transition to Nusantara, Jakarta is anticipated to retain its status as Indonesia's primary financial and business center. The city also remains a vibrant cultural and tourist destination, featuring landmarks such as the Istiqlal Mosque and historic Kota Tua.
