Coastal protection and urban development

Jakarta is used to flooding in the rainy season. In North Jakarta, flooding is set to become the worst in the area due to land subsidence. The average rate of subsidence is 7.5 centimetres per year, but in some coastal areas a subsidence rate of 17 centimetres per year has been measured. This will lead to flooding that will cause damage running into millions of dollars. However, the worst aspect is the fact that the safety of 10 million inhabitants and the sustainable economic development of Indonesia’s national capital are at stake. Indonesia needs to rise to this enormous challenge in order to protect the Jakarta metropolitan area against permanent flooding. Long-term investment is therefore needed to solve this problem.

National Capital Integrated Coastal Development (NCICD) is a mega-project which follows on from the Jakarta Coastal Defence Strategy Project (JCDS) in responding to the urgency of the extreme land subsidence that is happening in the northern part of Jakarta. Its objective is to reduce and prevent floods in the national capital by building three lines of sea defences which will be completed in a period of 20-30 years.

Not only does NCICD aim to provide a solution for the long-term protection of Greater Jakarta against flooding from the sea, but it also provides much more than that: it creates new space in the national capital for over 1.5 million people from all income classes in response to the limited space available in the Jakarta area by providing seaward expansion in a planned manner. It also helps to solve the current connectivity problems in West Java and Banten and addresses many of their current environmental problems. 

Since january 2017 the NCICD project entered its second development stage which should lead to the final investment decision in 2018. In NCICD-2 teams from Korea and Japan joined the consortium under Witteveen+Bos management.
