The Impact of the Utilization of Riparian Area for Settlements (Case Study of North Jayapura District, Jayapura City)

Abstract

The limitedness of area and plot of land in Jayapura City which are allocated for settlements has become a problem in Jayapura city. Population growth and high-rate of urbanization are impacted on the utilization of land which is not in accordance with its allocation. The modification of riparian area on the right and left sides of the river for settlements has reduced the function of the river, because in addition to river conservation, river has a double role as the securer of water source and as the protector of its surrounding area. Therefore, riparian area becomes more important to be considered. The riparian area in settlement area is assumed to be adequate for a 10-15 meters inspection road to be built on. The real condition of the rivers in North Jayapura District of Jayapura City, compared to the criteria of riparian area for settlement area, has not been inappropriate. The river’s function as the protector of its surrounding area has gone astray. If there is someday a flood, the impact may cause material damage or even life victims.
