Geography The district includes the delta of the Citarum River, where significant sedimentation still occurs. It is located on the Bay of Jakarta.
Since around 2009, coastal erosion has heavily impacted the low-lying, coastal villages, with several rukun tetangga (neighborhood-level administrative divisions) having been lost to the sea. The local government has been attempting to reduce the impact through the plantation of mangrove trees in vulnerable areas, which are prone to coastal flooding.
Economy Since at least the 1970s, the coastal communities has been engaging in milkfish and shrimp farming.
