From the results of monitoring at several locations, the rate of sea level rise surface 5-10 millimeters Indonesia reached per year, far above the estimated increase in global sea level surface estimated 1.5 millimeters per year.
The rate of increase in average sea level surface Indonesia is affected by six factors, but not dominated by climate change. So sub-directorate chief expressed Disaster Mitigation and Environmental Pollution of Marine and Fisheries Ministry
According to him, data sea surface level rise in Indonesia taken some instances. Coordinating Board of the monitoring survey and the National Mapping data obtained in Jakarta, Semarang, Jepara, Batam, Kupang, Biak, Sorong and the numbers 5-10 mm per year.
The results of Bandung Institute of Technology research shows the rate of increase in Belawan sea surface 7.83 mm per year, Jakarta 4.38 mm, 9.27 mm Semarang, and Surabaya 5.47 mm per year. Monitoring Research and Development Center Oseanologi Indonesian Institute of Sciences for Long, Lampung, showing the rate of increase of 4.15 mm per year.
Six factors
According to Subandono, paras sea level rise as the impact of climate change affected only two processes, namely the polar ice melting and sea water expansion process due to global warming. “There were six factors that cause,” he said.
Other factors, he added, is covering the impact of changes in the Earth’s crust due to tectonic activity, soil degradation caused by the earthquake or seismic activity and soil compression due to unstable soil conditions.
In addition, there is soil degradation due to human activities, such as taking soil water, gas and oil extraction, or the imposition of the building.
“The sixth factor, namely the variation due to climatic fluctuations like the La Nina phenomenon which brings warm water flow from the Pacific Ocean to Indonesia,” said Subandono. According to him, six factors causing sea level rise that looks important to know to set the note of adaptation and mitigation.
Indonesia continues to encourage the world’s attention to the impacts of climate change on the sea. This is characterized by the further destruction of coral reefs of the world or any other marine ecosystems. The Indonesian delegation to the UN Conference on Climate Change in Copenhagen, Danish, delivered by electronic mail has initiated the parallel activities of Marine Day (The Ocean Day) on December 14, 2009, opened the Prince of Monaco HSH Prince Albert II.
Former Head of Marine and Fisheries Research DKP Indroyono Soesilo in parallel activities that emphasize the importance of mainstreaming marine dimension in the process of global climate change negotiations.
According to Indroyono, programs to overcome the impact of climate change in relation to achieving the Millennium Development Goals (MDGs) needs to be realized in reality. Parallel activities attended by about 150 participants from 39 countries concerned with marine issues, coastal, and small islands that need to be addressed
