JAKARTA, KAMIS – Environmental disaster that hit various regions in the country is expected to continue to spread and worrying if the prevention factor is not the focus of treatment. Geologically, climatologically, and geographically, the territory of Indonesia is vulnerable.
Geological studies show that solid or solid rocks dominate rock structures in Indonesia. The rain above normal old tempo, supported by the slope of the hill, and the limited land cover caused ground movement.
Geologically, a lot of avalanche, banjir bandang, or other types of land movements in Indonesia. However, it depends on other conditions as well, says researcher at the Center for Research Geotechnology Institute of Sciences Indonesia, Adrin Tohari, told reporters in Jakarta, Wednesday (26/11). Indonesia's position in the volcanic belt (ring of fire) underlies the vulnerability.
Deputy III of the State Minister for the Environment for the Enhancement of Natural Resources Conservation and Environmental Damage Control, Masnellyarti Hilman, said that without the action of environmental improvement, natural disasters in the future will get worse.
Currently, natural disasters have hit many places. Spatial and conservation becomes the inevitable solution.
Data from the Ministry of Environment (KNLH): people in Java and Sumatra are most vulnerable to floods and landslides. Population density coexist with increasing potential of disaster.
Data on the extent of KNLH forest cover 2007/2008 shows that Java is only 7 percent, Nusa Tenggara (25 percent), Sumatra (25 percent), Bali (27 percent), Kalimantan (44 percent), Sulawesi (64 percent), Maluku percent), and Papua (81 percent). Without conservation, critical land will continue to grow.
Based on the potential of land movement, the area of ??West Java is most vulnerable to floods and landslides. There, the fault zone is densely populated with hilly contours, especially in the south.
Nationally, as many as 27 of 33 provinces are detected prone to floods and landslides.
Can be avoidedAccording to Adrin, the impact of ground movement can be avoided. Condition, the government focus on preventing, rather than tackling.
Potential data of land movement owned by the government and each month sent to the region. More detailed data, including precipitation forecasts, slope, and soil properties.
Unfortunately, he continued, the data that can and easily accessed it rarely used by the government as a basis for decision making. The government is reactive, moving after the disaster.
Such a disaster management model is expected to change, as the intensity and type of natural disasters related to climate change increase.
