Tropical peat surface oscillations are a function of peat condition at North Selangor peat swamp forest, Malaysia. Frontiers in Environmental Science, 11, Article 1182100. https://doi.org/10.3389/fenvs.2023.1182100

Tropical peatland condition across southeast Asia is deteriorating as a result of conversion to agriculture and urban zones. Conversion begins by lowering the water table, which leads to peat decomposition, subsidence and increased risk of large-scal...
