Abstract
Bogor Regency is vulnerable to multi-disaster-threats areas such as flood, erosion, and landslide. The purpose of this study was to analyze the ecosystem services in Bogor Regency. The aspect of ecosystem services is the function of prevention and protection from natural disasters. Land-use change and land facet maps are primary data used in determining the ecosystem services index of disaster prevention and protection. The SPOT 4, 6, and 7 were interpreted to determine changes in land use from 2010 to 2017. The land facet data was sourced from the Geospatial Information Agency (BIG). The analysis in this study was carryout by Analytical Hierarchy Process (AHP) sourced from 35 contributors. The results showed that 8.94% of the total area of Bogor Regency had undergone land-use changes from 2010-2017. The most extensive land-use changes were plantation (2.65%) and farming fields (2.47%). The most vulnerable area to the threat of a multi-disaster is the eastern part of Bogor Regency. This area is already congested with settlements, so that the vulnerability and element at risk are fairly high. Meanwhile, results gained from the AHP show that forests play an important role in disasters prevention and protection in Bogor Regency.
