Four districts on the north coast of Jakarta could be submerged within a century if the city administration does not address environmental issues in its spatial planning policies, an expert said.
“Research shows that the sea level on Jakarta’s coast has increased at a rate of 57 millimeters per year because of the effects of global warming on the polar ice caps,” Bandung Institute of Technology (ITB) oceanology department chief Safwan Hadi said Friday.
The districts of Pademangan, Penjaringan, Tanjung Priok and Cilincing in North Jakarta would be flooded by a half-meter of sea water by 2100, Safwan said.
“However, the city will probably lose those areas sooner as we also find that soil in the area is subsiding by between 5 and 12 centimeters each year,” he added.
The Indonesian Water Society previously stated that Jakarta was slowly sinking, warning that North Jakarta will be completely submerged within 50 years when the sea would reach Jl. Hayam Wuruk in Central Jakarta, around 5 kilometers inland.
Safwan criticized the Jakarta administration’s decision to continue development plans in North Jakarta despite expert suggestions to put the plans on hold pending a reassessment to better cope with deteriorating environmental conditions.
If the administration wanted to continue its development plans in North Jakarta, he urged officials to start making plans to prevent the city from sinking, Safwan said.
“The administration can build strong dikes following the Dutch example, where their country’s landscape and features are similar to Jakarta,” he said, adding that about 40 percent of the area in Jakarta was below sea level. (rch)
