Impact of Climate Change on Floods in Bengawan Solo River Basin, Indonesia and its Adaptation and Mitigation Measures
In late December 2007 and early January 2008, more than 100 people have been killed and hundreds of thousands have been affected in East and Central Java Provinces by the flooding and landslides, which began on December 25, 2007. During that time, persistent heavy rains led to overflowing rivers, flooding and landslides throughout Indonesia, resulting in numerous fatalities and crop losses. The two largest river basins in Java Island i. e. Bengawan Solo and Brantas River basins, were the hardest hit on the basins from flooding and landslides. Based on Multi-satellite Precipitation Analysis (MPA) produced at NASA s Goddard Space Flight Center for December 24, 2007 to January 2, 2008, the highest rainfall totals for the period were over 250 millimeters (about 10 inches). Although the highest amounts were over water, parts of Java received in excess of 6 to 8 inches. Deforestation in the region may have contributed to the devastating mudslides. The latest flooding in Bengawan Solo River basin occurred four times in January to March 2009, caused economic disturbances in the region with economic losses estimated of about Rp. 1,000 billion. In the future, increased precipitation intensity and variability in the basin due to climate change are projected to increase the risks of flooding. The flood magnitude and frequency in the basins have increased significantly and become significant issue in the basin s water resources management. To cope with flood hazards that happen frequently in the Bengawan Solo River basin, some mitigation and adaptation measures had been done and still need to be done in the basins, involving Central Government, Provincial Government, Regency/Municipality Government, communities, NGOs, etc. This paper will discuss the impact of climate change on increasing flood magnitude and frequency, taking into account flooding occurrences in the Bengawan Solo River basin, Indonesia and its mitigation and adaptation measures.
