Overview

Investigates climate anomalies affecting peatland cover change in Sumatra, highlighting environmental implications.

Key Points

  • The research aims to assess how tropical climate anomalies impact land cover changes in Sumatra's peatlands.
  • Analyzed Landsat imagery from Landsat 5 and Landsat 8.
  • Utilized Random Forest machine learning classification.
  • Identified climate anomaly periods using ENSO and IOD indices.
  • Integrated various spectral indices to enhance classification accuracy.
  • Achieved classification accuracies of 89-92% with kappa values of 0.85-0.90.
  • Identified the 2015/2016 El Niño event as causing over 51% peatland degradation.
  • Noted a 23-38% degrade during the 1997/1998 El Niño.
  • Observed limited impact from the 2019 positive Indian Ocean Dipole.
