Degraded peatland is caused by forest clearing and the construction of artificial water 9
networks. When water management isn't implemented across land uses in the entire peatland land- 10
scape, then it will be a big issue that causes a water deficit and leads to increasing droughts and 11
fires. Effective restoration must first identify the part of Peatland Hydrological system Units (PHUs) 12
with insufficient water storage and resources. This study used intercorrelated factors of topography, 13
wetness indices, peat depth, fire frequency, and hydrological conditions, as the evaluation parame- 14
ters, within individual sub-PHUs to determine the most degraded areas that require intervention 15
and restoration. Sub-PHU was determined based on the peat hydrological unity concept by identi- 16
fying streamline, outlet channels, peat-depth, slopes, and network connectivity. Global hydrological 17
data using TerraClimate and CHIRPS, combined with field observations, were used to validate and 18
calculate each sub-PHU's water balance and dry periods. Soil moisture, vegetation density, and fire 19
frequency were extracted from multispectral satellite images (e.g., Landsat 8, MODIS-Terra, and 20
MODIS-Aqua). Each parameter was ranked by the score for each sub-PHU. The parameters that can 21
be ranked were only the ordinal type of number. The lowest ranks indicated the most degraded 22
sub-PHUs requiring peat rewetting interventions |
