Indonesia’s Jakarta city continues to sink under ground

Indonesia plans to move its capital city from Jakarta on the island of Java to a new forest city on the island of Borneo called Nusantara. According to Eka Permanasari, associate professor in urban design at Monash University, Australia, Jakarta is a city struggling to keep its head above water. “It’s been attacked from both sides – from the river and from the land”.

The city experiences extreme amounts of rainfall, worsened by climate change, which regularly causes severe flooding. Coupled with this, massive extraction of ground water from aquifers underneath the city is causing the Jakarta to sink. “If you go to the northern part of Jakarta, you may see the road is higher than the houses next to it. In some other areas, it’s actually sinking more than 15cm per year,” says Permanasari.

Due to the problems facing Jakarta, plans to relocate Indonesia’s capital have a long history. During the colonial era, the Dutch considered abandoning the city, then called Batavia, due to flooding, high temperatures and disease linked to stagnant water. Since Indonesian independence in 1945, successive administrations have also floated plans to relocate the capital, but these never came to fruition.

Now, the government of President Joko Widodo, known as Jokowi, is forging ahead with a new project, estimated to cost around US$35 billion. In January, Indonesia’s parliament passed a bill to relocate the country’s capital city from Jakarta on the island of Java to the East Kalimantan province of Borneo. The government then announced the city’s name: Nusantara, which loosely translates as archipelago in sanskrit.

Hendricus Andy Simamarta is a lecturer in urban planning at the University of Indonesia and president of the Indonesian Association of Urban and Regional Planners. He says a big reason for relocating the capital is to shift Indonesia’s center of gravity away from Java. “We are very dependent on Java economically, more than 50% of our economy is located in Java,” he says. Simamarta is skeptical that moving the capital to East Kalimantan will re-balance the economy, but he says at least it can start to “re-orientate our mindset of development”.

The dream for Nusantara is for a new high-tech, smart city, surrounded by forest. Borneo is an island with rainforests home to an abundance of different species, including orangutan and Asian elephants. However, Alex Lechner, an associate professor in landscape ecology at Monash University, Indonesia, who is based in Jakarta, says the area planned for Nusantara’s construction is currently covered by eucalyptus plantations – monocultures with less biodiversity than intact rainforest.

Lechner is impressed with eight principles set out for Nusantara’s development, including on carbon neutrality and circular economy approaches. “If it all looks like it’s looking like on paper, there’s potential for this city to be this shining example for southeast Asia of what green and sustainable development should look like,” he says.

But he’s also concerned about what might happen on Borneo outside Nusantara’s footprint. “What happens to all the development which this city encourages outside of the city boundaries? Is this going to be developed sustainably?” Lechner says if more roads are built to connect Nusantara to other parts of Borneo, this could produce a “fish-bone effect” with small roads leading off into the forest, which could have a “whole raft of cascading spillover effects on the environment and especially on diversity”.
