Peat Management
Peatlands represent a unique type of ecosystem due to their high organic matter content. Under natural conditions, peat soils are water-saturated; however, when peatlands are degraded as a result of deforestation and drainage construction, the water within the peat easily flows out, causing the peat to dry (Turetsky et al., 2015; Taufik et al., 2015; Lanen, 2015).
The groundwater table level plays a critical role in maintaining the sustainability of peatland ecosystems. A decline in the water table is closely associated with an increase in greenhouse gas emissions resulting from peat decomposition (Sundari et al., 2012). Lowering the groundwater table also significantly contributes to the risk of peatland fires, as the surface layer, composed mainly of organic material, becomes dry and highly flammable. Therefore, maintaining an optimal groundwater table level is essential for sustainable peatland management.
The Company's efforts in managing and restoring peatland ecosystems include monitoring groundwater levels through both manual and automated observation wells, constructing water gates and canal blockings, and submitting regular reports through the SIMPEL web-based reporting system.
