Jakarta, Indonesia, has become the fastest land subsidence city in the world because of uncontrolled exploitation of groundwater. Moreover, Jakarta itself has a low geographical environment and is particularly vulnerable to seawater intrusion. 70% of the land in Jakarta is covered with concrete and asphalt, so the surface water can't penetrate into the ground and the drainage system deteriorates. Heavy concrete also aggravated the subsidence of the ground.

Jakarta, Indonesia is currently facing many problems. Jakarta population10180,000. Coupled with environmental pollution and shortage of drinking water, these problems have led to a very serious land subsidence problem in Jakarta. In addition, Jakarta itself is below sea level. Completely uncontrolled pumping of groundwater as drinking water and bathing water led to the intensification of land subsidence.

Jakarta is the city with the fastest land subsidence rate in the world, and it is also because of the rapid development of Jakarta. The relatively dense population led to the land subsidence of the whole city of Jakarta. Jakarta is located on the northwest coast of Java. Jakarta is located in a swamp with many rivers, and its terrain is particularly vulnerable to seawater intrusion. The imperfect tap water system leads to the fact that although Jakarta is a city with a huge population, most of it uses groundwater, which leads to serious land subsidence.

The tap water construction in Jakarta itself is relatively backward, and the dense population leads residents to dig wells for water privately. In addition, the dense population has brought about the process of urbanization, resulting in 97% of the land being covered with concrete and asphalt, which makes the precipitation on the ground unable to penetrate into the underground and replenish the groundwater in time. Under such circumstances, Jakarta has become the city with the fastest land subsidence rate in the world.
