Why Indonesia is building Nusantara

Jakarta is overcrowded, floods, and is sinking, so in 2019 Indonesia decided to build a new capital from scratch in the forests of Borneo. The core is nearly built, but the move keeps slipping: the government now aims to make it the political capital by 2028.

Why leave Jakarta

Indonesian officials talked for decades about moving the capital. Jakarta is severely overcrowded and prone to flooding because it lies below sea level and its environment keeps degrading.[1] NPR describes it as the world’s largest city, polluted, overcrowded and sinking.[3]

In 2019 President Joko Widodo announced a plan to build a new capital and move the government there.[1] The site, about 2,500 km² on Borneo, was chosen partly because it is inland in an area with few earthquakes and volcanoes, and partly to lessen the gap between Java, the most populous island, and the rest of the country.[1]

Building it

A law in 2022 made building the capital a legal requirement, and construction began that year.[1] Much of the site is peat bog and swamp under dense rainforest, and critics worry about the forest and endangered orangutans; supporters point to planned wildlife corridors.[1] Local environmental groups say the work has already destroyed mangroves around Balikpapan Bay.[3]

On 17 August 2024 Indonesia held its Independence Day ceremony at Nusantara for the first time. Because lodging and food were limited, the guest list was cut from 8,000 to 1,300.[2]

Slower under Prabowo

Prabowo Subianto, Widodo’s ally, became president in October 2024.[1] State funding for 2026 was cut to half of the previous year’s, and Prabowo made his first visit to the site as president in January 2026.[3] In 2025 he signed a regulation calling Nusantara the “political capital” from 2028, rather than the national capital.[3]

By early 2026 the core government district was nearly complete, with about 10,000 residents, roughly a thousand of them civil servants. The head of the Nusantara Capital City Authority, Basuki Hadimuljono, says the president plans to move there in 2028, once the legislative and judicial buildings are finished.[3]
