Essay On Land Subsidence In Jakarta

Background

Jakarta has a population of about 9.6 million people and in the last three decades, urban development of Jakarta has grown very rapidly in many sectors starting from industry, trade, and transportation until real estate. The increase in Jakarta’s population and urban development had cause several environmental problems including land subsidence.

Land subsidence is a gradual settling or sudden sinking of the Earth 's surface owing to subsurface movement of earth materials. The level of soil in Jakarta is slowly degrading due to the disturbance of the soil consistency, and the water level in the soil is slowly decreasing, and now the sea level in Jakarta is higher than the ground level. In another word, Jakarta has been experiencing

It will also list down and explain each of the solutions that can be done in order to prevent and reduce the occurrence of land subsidence in Jakarta.

Main Cause of Land Subsidence

There are four different types of land subsidence that can occur in the Jakarta basin, which are: subsidence due to groundwater extraction, subsidence induced by load of constructions, subsidence caused by natural consolidation of alluvial soil, and subsidence occurred by tectonic subsidence. In general, most of the land subsidence is strongly caused by the urban development activities in Jakarta.

Overpopulation is a function of the number of individuals compared to the relevant resources, such as the water and essential nutrients they need to survive. It can result from an increase in births, a decline in mortality rates, an increase in immigration, or an unsustainable biome and depletion of resources.. Can speeds up the process of natural land subsidence.

This process includes the increase in population size, Increase in water needs, High water necessities, Increase in groundwater Pumping to fulfill the water need, Over-pumping of ground water, Speeds up the process of natural land
