Abstract
The projected climate change will likely impose landslide in several regions in Indonesia. Currently, landslides frequently hit Indonesia causing loss of life and property. For example, in the period of 2003-2005 Indonesia suffered from 103 landslides across seven provinces with a huge amount of loss. Landslides must be taken into account in any comprehensive water related study, considering that water is often a trigger in landslide occurrences. There are at least 918 landslide zone, with Central Java having the most landslide zone (327 location), West Java (276 locations), West Sumatera (100 locations). This paper identifies several high risk regions throughout Indonesia based on the national level of climate risk study. Based on 30 year climate projection, North Sumatera area has increasing of landslide risk especially in September. Otherwise in Java-Bali, the increasing of landslide is in December, January and February, wherein it could be evaluated that in February due to rainfall accumulation. In Sulawesi, especially in North Sulawesi, the increasing of rainfall is in September, otherwise in Middle Sulawesi is in December which is not significant increase and reversal in another month. In the other hand, in Papua has high increasing rainfall especially in January. This paper concludes with some possible actions to adapt to the impacts of climate change to landslide.
