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.
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.

These two articles became the source of debate regarding Presidential Decree No. 52/1995, which was the primary legal basis for the reclamation of Jakarta Bay by the DKI Jakarta Government. The northern coast of Jakarta is planned to undergo land reclamation. The area to be reclaimed will cover 17 islands.
Subsidence frequently causes major problems in karst terrains, where dissolution of limestone by fluid flow in the subsurface creates voids (i.e., caves).If the roof of a void becomes too weak, it can collapse and the overlying rock and earth will fall into the space, causing subsidence at the surface.
A study in an arid agricultural region of Arizona [3] showed that, even with a water level recovery of 100 ft after groundwater pumping was stopped, the land surface continued to subside for decades. This is a result of the continued dewatering of aquitards (fine-grain layers that slow the movement of groundwater) from stresses mentioned in the ...
From 18:30 WIB (11:00 UTC, WIB is UTC+07:00) on 1 January until 12:00 WIB (05:00 UTC) on 2 January, the government temporarily waived all toll road fees in Jakarta. [9] At many parts of the city, water levels reached 30 to 200 cm. Some places, such as Cipinang Melayu, East Jakarta, water levels peaked at four metres. [10]
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 ...
