Floods in Jakarta

Other contributing factors include clogged sewage pipes and waterways that service an increasing population, in addition to deforestation near rapidly urbanizing Bogor and Depok in Jakarta's hinterland.

Jakarta is an urban area with complex socio-economic problems that indirectly contribute to triggering a flood event.

On January 15, 2013, a serious flood affected downtown Jakarta, as well as several other areas surrounding the city, such as West Java and Banten, as a result of heavy rain and waterways clogged with garbage and other kinds of debris.

A temporary retaining wall was constructed until workers finished rebuilding a section of a canal dike.

It is an online, open-source platform, which relies on participatory mapping conducted by local communities, private and public actors who collect the detailed information about a given area and share it, meet the needs in disaster situation.

From 2000 to 2050, the potential coastal flood extent is estimated to increase by 110.5 km2 due to both land subsidence and sea level rise.

[45] At the same time, the groundwater has lost its capacity to recharge due to the lack of watershed areas and overpopulation in the capital.

Not only must the customer pay for the tariff, which is higher than other Indonesian cities,[46] the installment fees often burden the poor households to connect to the tap.

In an effort to solve the problem, construction of an 8 km sea wall along the coast was officially launched on October 9, 2014.
