JAKARTA (AFP) — Separated by a road and a viscous finger of black, garbage-choked water, the stilt-house slum of Muara Baru and the BMW car dealership that faces it appear as if from different worlds.

But on December 6, 2025, these two extremes of the Indonesian capital will have something in common as a World Bank study shows that unless action is taken, they and much of the coastal city of 12 million will be submerged by seawater. Experts have pinpointed that date as the next peak of an 18.6-year astronomical cycle, when sea levels will rise enough to engulf much of Indonesia’s low-lying capital. Climate change is causing sea levels to rise, but the study’s authors say the main problem is that Jakarta is sinking under the weight of out-of-control development. “The major reason for this is not climate change or whatever, but just the sinking of Jakarta,” says JanJaap Brinkman, an engineer with Dutch consultancy Delft Hydraulics who worked with the World Bank on the study. “We can exactly predict to what extent the sea will come into Jakarta.”
