2020, Jakarta Area Half Being Underwater

Jakarta Coastal Defence Strategy (JCDS), in a research consortium in the know as much as 40 percent of Jakarta was under sea level, and the estimate to about 10 the next area which is under sea level will increase to 50 percent. This study was taken in 2010 and was conducted to study the preparation of giant dikes around the coast of north Jakarta. The results were also mentioned, the decline in soil or land subsidence in Jakarta occurred since 1974 and will continue to happen. This condition is exacerbated by rising sea levels due to global warming (global warming). Data taken in 2010 was mentioned, based on quantitative data and land subsidence in Jakarta, from 1974 to 2010 found the fact there has been land subsidence and 4.1 meters. It happened in the area of ​​Muara Baru, Cilincing, North Jakarta. A number of other areas like the West Cengkareng also decreased 2.5 meters. Then Daan Mogot 1.97 meters, 1.88 meters Ancol (monitor points in the tourist area of ​​Ancol), Cempaka Mas 1.5 meters, Cikini 0.80 meters and 0.25 meters Cibubur.Data also mentioned, since the 1974-1982 land subsidence has not occurred significantly as it is today, because the use of ground water is not high and buildings are also still small. Meanwhile, starting 1982-1991, the land of Jakarta began to decline, and in 1991-2010 was more widespread condition.
Land subsidence has also occurred due to suction of underground water for household and industrial purposes. Makin decrease the soil surface, then the sea will be easier to deal with is masuk.Langkah while membangunan though still seporadis sea dike. Embankments, among others are in Muara Angke, Muara Karang, Pluit, Outer Trunk, Cilincing, Marunda and Regis on the North Coast Jakarta in 2008 and 2009.
Concrete dike or levee constructed stone approximately 3,000 meters in length with a height which varies between 1 to 3 feet above ground level.


However, according to Fauzi Bowo, the existing embankment is not adequate. Predicted, in 5 to 10 years ahead, Establishments must have the latest penanggulan system. Moreover, the system currently used can not be applied.
The embankment is later, said Fauzi Bowo, polder or reservoir system using water. Should be built further forward towards the sea that connects the nearest island in the Bay of Jakarta. This system has been implemented in the Netherlands and New Orleans, United States.
"Although the sea water is high, but the area below the sea surface remained dry because there is a giant dike that will pump water into the sea," he said.
With the levee that will be made in the hope that the territory which is under sea level in order to stay dry eperti usual, so that society no longer need to worry about the flood that will hit the area.
