What Happened to Jakarta?

Jakarta, a sprawling megacity and for decades the vibrant capital of Indonesia, has been at the epicenter of the nation's economic and political life. However, its rapid, unplanned growth has led to a confluence of environmental and infrastructural crises, most notably being the fastest-sinking city in the world. This existential threat, coupled with chronic issues like severe traffic congestion, air pollution, and recurrent flooding, ultimately prompted the Indonesian government to embark on the ambitious project of relocating the national capital.

The city's precarious situation is largely attributed to excessive groundwater extraction by its burgeoning population, which has caused the land to sink at an alarming average rate of 3.5 centimeters per year, with some northern areas experiencing subsidence of up to 11-20 centimeters annually. As of early 2026, approximately 40% of North Jakarta lies below sea level, making it highly vulnerable to tidal flooding and rising sea levels. Compounding these issues are extreme rainfall events, exacerbated by climate change, and an overburdened drainage system, leading to widespread inundation. The sheer scale of its population, estimated at 42 million for the urban agglomeration in late 2025, also contributes to severe traffic congestion, ranking Jakarta as the 24th most congested city globally in early 2026, and persistent air quality problems.

In response to these escalating challenges, President Joko Widodo first announced plans to move the capital in 2019. A significant turning point occurred in March and April 2024 with the passing and signing of Law Number 2 of 2024 on the Special Regional Province of Jakarta. This legislation formally outlined Jakarta's transition from a 'Special Capital Region' to a 'Special Regional Province' (DKJ), effectively revoking its status as the national capital. By November 2024, the Indonesian parliament officially designated Jakarta as a special region. The new capital, Nusantara, located in East Kalimantan on the island of Borneo, is envisioned as a green, smart, and sustainable city.

As of early 2026, Jakarta continues its transition. While it has shed its administrative capital role, it remains the undisputed economic and financial powerhouse of Indonesia, a global city connecting business centers worldwide. The government aims for Jakarta to become a major economic and financial hub. Efforts are underway to mitigate its environmental woes, including ongoing flood management strategies like weather modification operations and river normalization programs, as well as an ambitious target for 100% waste management by 2026. Meanwhile, construction in Nusantara is progressing, albeit with some delays and a reported scaling back of its initial scope to primarily a 'political capital' by December 2025. President Prabowo Subianto, who took office in October 2024, has reaffirmed his commitment to the Nusantara project, with key government buildings targeted for completion by 2028 and the relocation of civil servants expected to continue in stages.

The future of Jakarta involves navigating its ongoing environmental vulnerabilities while leveraging its established economic prominence. The relocation of the capital is intended to alleviate some of the pressure on Jakarta, allowing it to focus on sustainable urban development and maintain its role as a global economic player. However, challenges persist, including ensuring equitable development across the Greater Jakarta area, addressing policy disparities in environmental management with neighboring regions, and securing sufficient investment for both Jakarta's resilience and Nusantara's completion. The OECD's revised economic growth forecast for Indonesia in March 2026, at 4.8%, highlights the broader economic context influencing these large-scale urban and national development projects.
