Abstract
In Indonesia, extensive tropical peatland has been facing land degradation due to deforestation and drainage canalconstruction. Such activities lead to the decrease ofgroundwater level (GWL), accelerating the peat decomposition, followed by peatland subsidence. This study addresses to estimate a three-year (from Jan. 2018 to Jan.2020) tropical peatland subsidence over Kalimantan,Indonesia, using the time-series interferometric syntheticaperture radar (TInSAR) technique by Sentinel-1A. TInSARanalysis revealed the apparent large displacement found in2019 due to a significant decline of GWL caused by positiveIndian-Ocean dipole mode (IOD) event compared to otheryears. Furthermore, we employed GWL derived fromsatellite-based remote sensing data to investigate therelationship between subsidence and GWL and showed a mutual relationship.
