Climate Change Impacts Related Flood Hazard to Communities around Bantimurung Bulusaraung National Park, Indonesia a.Center for Natural Heritage, Biodiversity and Climate Change, Hasanuddin University, Makassar, South Sulawesi, Indonesia, email rolandbarkey[at]gmail.com Abstract Climate variability in a region leads to the increasing rainfall intensity during the rainy season and the increasing number of days of dry season. This condition is happening in most part of Indonesia, especially in the South Sulawesi province where it has a quite complex characteristic of the ecosystem. One of them is Bantimurung-Bulusaraung National Park with a special characteristic of landscape in the form of karst area and the people in the buffer villages located in Maros, Pangkajene Kepulauan and Bone Regions depend their livelihoods in the park. One of the impact of climate changes happening around the National Park area is the increasing potential of flood. The flood mostly occurs due to the high rainfall in the rainy season supported by the characteristics of land in the form of karst area that very quickly passes the water. Flood hazard analysis in Bantimurung-Bulusaraung National Park area was assessed by using Soil and Water Assessment Tools (SWAT) model on actual condition (climate period 2004-2013) and projection of climate change in 2030s using scenario RCP 4.5 (rainfall scenario tend to decrease) and RCP 6.0 (rainfall scenario tend to increase). Based on the SWAT model analysis results, it is known that there are areas of the buffer villages of Bantimurung-Bulusaraung National Park, which has a very high level of flood, which the actual condition of the affected area is 10,380.31 ha and on climate change projection of scenario RCP 4.5 covering 9,061.99 ha and RCP 6.0 scenario covering 24,188.26 ha.
