Riparian is undefined government land and can be converted to other utilization. Riparian areas have natural connections throughout the watershed; they are particularly sensitive and often degraded by human use. One of them is the informal settlement, such as the residential areas in the Ciliwung River riparian which changed the land function from a conservation area. This research conducted in three sites of the Ciliwung River riparian section that is represented by the upper part (Kelurahan Katulampa); middle part (Kelurahan Babakan Pasar); and the lower part (Kelurahan Kedunghalang). The purposes of this research are: 1) to analyze the riparian settlement yard in upper part, middle part, and lower part, 2) to figure out people’s motivation for the management of land yard, and 3) to calculate the potential of land as water catchment areas and to support household-scale agricultural production. The remaining of land in the informal settlement is upgraded to fulfill the riparian function and to improve local people’s welfare.
