Land subsidence in Jakarta is mainly caused by the overuse of groundwater. [47] At the same time, the groundwater has lost its capacity to recharge due to the lack of watershed areas and overpopulation in the capital. Without any groundwater regulation in place, buildings in Jakarta are drawing water from the ground at an unprecedented rate.
Jakarta lies on a low flat basin 23 feet (7 m) above sea level. 40 percent of that, particularly the northern areas, is below sea level. Given the continuous groundwater extraction and the pressure of skyscraper developments, Jakarta is sinking at 5 to 10 centimeters per year, up to 20 centimeters.
Drivers, processes, and impacts of sinking cities [1]. Sinking cities are urban environments that are in danger of disappearing due to their rapidly changing landscapes.The largest contributors to these cities becoming unlivable are the combined effects of climate change (manifested through sea level rise, intensifying storms, and storm surge), land subsidence, and accelerated urbanization.

Floods have hit Jakarta several times in the past, including in 1621, 1654, 1918, 1942, 1976, 1996, 2002, 2007, 2013 and 2015. A significant contributing factor is that a substantial part of Jakarta is low-lying; some 24,000 ha (240 km 2) of the main part of Jakarta are below sea level. [6]
The capital city Jakarta is subject to severe floods from time to time which usually cause some loss of life and significant damage to public and commercial infrastructure. In January 2014, for example, over 20 people lost their lives during widespread flooding and at one stage over 60,000 citizens were temporarily housed in nearly 250 ...
Groundwater overexploitation occurs in heavily populated coastal areas of Java, including in Jakarta and Semarang. In Jakarta, it has caused seawater intrusion up to 10 km (6.2 mi) from the coast and land subsidence at a rate of 2–34 cm/year in east Jakarta. [7] In Semarang, land subsidence occurs at a rate of 9 cm/year. [8]
As Southern California recovers from last month’s devastating wildfires, heavy rain resulted in pockets of flooding, blocked roadways and mud piling up around recent burn scars.
The mean sea level rise globally was 3–10 mm per year, while the subsidence rate for Jakarta was around 75–100 mm per year, making the relative rise in sea level nearly 10 cm per year. [39] Continued carbon emissions at the 2019 rate, in combination with unlicensed groundwater extraction, is predicted to immerse 95% of Northern Jakarta by 2050.
