Abstract
Land use changes greatly affect the value of ecosystem services. This study aims to analyse the sensitivity of ecosystem services especially food provisioning, affected by land use changes in Bogor Regency. The method used is visual interpretation and manual digitization of Indonesian Topographic Map (RBI) and the SPOT-7 with a resolution of 1.5 meters. The sensitivity assessment of ecosystem services is carried out through analytical hierarchy process (AHP). The results of the study showed that there was a changing in land use of 8.31% in the period 2000 to 2017. Forests area to be the most significant changes contribute 1.86%. Changes in land use are influenced by regional development and population growth, so that conversion of land use occurs massively at some point. Regulatory and supply functions are the most sensitive elements of ecosystem services to land use changes. Conversion of water catchment area causes a decrease in soil infiltration capacity and triggers erosion. This phenomenon leads to land degradation and natural disasters.
