Monitoring tropical peatlands subsidence by time-series interferometric synthetic aperture radar (InSAR) technique

This chapter evaluated the potential of SBAS InSAR technology to monitor the land subsidence and its environmental impacts in tropical peatland area from Sintang Regency, Borneo Island, Indonesia. Result shows that 0.354 Mt carbon was lost annually due to this peat subsidence. Hence, it is suggested that periodic monitoring of Indonesian peatlands is essential for sustainable land management, because these peatlands are still degrading and changing to other land use classes. The high temporal resolution and freely available Sentinel-1 have the potential to deal with near real-time monitoring.
