DEBRIS FLOW DISASTER MITIGATION THROUGH COMMUNITY-BASED INTEGRATED SEDIMENT MANAGEMENT (BEST PRACTICE IN MT. MERAPI AREA, INDONESIA)
Abstract: Mt. Merapi is one of
many active volcanoes in Indonesia which erupts frequently. The small eruption
occurred nearly every year, whereas the big ones occurred at approximately once
every five years. The eruption often produces impacts at both positive and
negative view points, such as production of sediment as construction material and
damage on infrastructures due to debris flow occurrences respectively. The
eruption produces two types of disasters, i.e. primary disaster (such as ash
fall, pyroclastic flow, and lava flow), and secondary disaster such as debris
flow. This paper presents the long term effort on the development of community
participation in the sand mining management as one of strategic disaster
mitigation activities. The raising awareness of the community on the necessity
of conducting proper sand mining management and its effect on reducing the risk
due to debris flow disaster has shown the effectives of the approach being
introduced. The local government acceptance on the presence of the community
participation in the whole system of sediment management may involve further
collaboration between the local government authority and community society in
the future.
