Assessment of Land Use Land Cover Changes and their Impact to Groundwater Quality Index in Kendari City - Indonesia

Abstract

Population growth and human activities in Kendari has been linked to cause of forest loss. This research employed Landsat images to identify Land Used and Land Cover (LULC) changes during 1998-2018, as well as investigated their impact to water ground quality. During last 20 years, LULC of Kendari has demonstrated a substantial change, in which deforestation and residential areas greatly increased. Growing population needs more land for settlement and economic facilities. Groundwater quality was successfully classified into 3 categories, namely good (20 samples), moderately polluted (18 samples), and polluted (2 samples). Our experimental data concluded that land use changes substantially contributed to state of groundwater in Kendari; hence, further sustainable development is envisaged in order to manage land use, ensuring availability of clean water for local people
