“…The difference in height between each point or location becomes the difference in topography at that point (Figure 2). In addition to the measurement of groundwater level dynamics, the CO2 emission rate was also estimated using the carbon loss model of GWL adapted from Carlson et al [17] for palm oil (Elaeis guineensis) plantation: CL=5.4+0.21x GWLx-100*3.67 and Hooijer et al [15] for acacia (Acacia mangium) plantation and deforested peatland: CL = 21-69 GWL and CL=9-84× GWL…”

“…In addition, the degraded peatlands are one of the triggers for the peatland subsidence and the lowering of the water table. This has caused Indonesia's peatlands to shift from carbon sinks to carbon emitters from forest and peatland fires [11][12][13][14][15][16][17][18][19][20][21][22]. Peatland fires occur almost every year in Indonesia, causing haze disasters that affect the economy and public health.…”

“…Carbon loss models have been developed as a function of the water table from plantation areas on peatlands [11][12][13][14]. In addition, few studies have investigated how land use and topography can affect the groundwater table (GWL) in the context of peatland domes [15][16][17]. Presidential Decree No.…”

Tropical peatlands are wetland ecosystems formed from the accumulation of organic matter over thousand of years period. Indonesia has an area of about 13.5 million ha and play important roles for society and the environment. The development of drainage canals has caused peatlands to become dry and degraded, rendering them highly susceptible to fires. Peatland restoration through rewetting activities with canal blockings can restore the hydrological function of peatlands. In addition, groundwater level (GWL) also affects carbon emissions from peatlands. This study aims to determine the distance of canal blocking effect on groundwater level so that it can be known which areas have a lower risk of fire and carbon emissions in peatlands. This study compared areas affected by canal blocking with those without canal blocking. The results of this study show the significant effect of canal blocking in increasing the groundwater level in areas with <100 m distance from the canals and with different types of land use. The average GWL of peat during one year of monitoring period was around - 26.67 ± 2.4 cm at the location of the monitoring well close to the canal with canal blocking, equivalent to carbon emissions of 26.5 tCO2eq ha−1 year−1. This is lower than the average GWL of those areas without canal blocking that was - 58.67 ± 3.1 cm, which is equivalent to carbon emissions of 57.8 tCO2eq ha−1 year−1.

Groundwater resources are one of the natural resources that need to be preserved. The main problem of groundwater in coastal areas is the intrusion of seawater into the groundwater aquifer. The problem will be even more complex when the land is covered by peat soil. The purpose of this study was to investigate the potential of groundwater in the western part of Bengkalis Island. Geoelectrical resistivity data was taken with the Schumberger configuration with the increase in the electrode distance being varied to obtain accurate measurements. Groundwater samples were measured to obtain the physical character of the groundwater. The results show that groundwater close to the shoreline has been contaminated by the presence of seawater intrusion. However, in areas that are a bit far from the shoreline, the shallow aquifer groundwater conditions are still not contaminated by seawater. It can be concluded that the presence of seawater in the aquifer is caused by the trapping of seawater in the aquifer during sediment deposition in the past.

“…Adverse impacts of peatland degradation include: greenhouse gas emissions, pollution of surface and ground waters, loss of biodiversity, land subsidence and catastrophic peat fires (Ziegler et al, 2021). The main environmental threat related to oxidization of peat following peatland drainage involves land subsidence (Silins and Rothwell, 1998;Camporese et al, 2004;Camporese et al, 2006;Gebhardt et al, 2010;Leifeld et al, 2011;Zanello et al, 2011;Nagano et al, 2013;Pronger et al, 2014;Fell et al, 2016;Grzywna, 2017;Lipka et al, 2017;van Hardeveld et al, 2017;Nusantara et al, 2018;Evans et al, 2019;Karlson et al, 2019;Khasanah and van Noordwijk, 2019;Ahmad et al, 2020;Khakim et al, 2020;Oleszczuk et al, 2020;Rodriguez et al, 2020, Rodriguez et al, 2021Anshari et al, 2021;Basuki et al, 2021;Ikkala et al, 2021;Ziegler et al, 2021;Anshari et al, 2022).

Rapid development and growing availability of Unmanned Aerial Vehicles (UAV) translates into their more wide-spread application in monitoring of the natural environment. Moreover, advances in computer analysis techniques allow the imaging performed with UAVs to be used in creating Digital Elevation Models (DEM) and Digital Surface Models (DSM). DEMs are often employed in studies on geology, environment, engineering, and architecture. The presented paper discusses the procedures enabling the making of a precise DEM, discusses the aerial imaging data processing technique as well as determines the accuracy of obtained products in comparison with an existing Digital Elevation Model. Based on available literature the author indicates four sets of input parameters applicable in UAV imaging. Data collection missions were performed on two separate days in the area of a small peatland located in the Tuchola Pinewood, Poland. The study aims to address two research issues. Firstly, the author investigates the possibility of creating a DSM based on UAV imaging performed under unfavorable conditions and indicates whether results obtained via this method display sufficient quality to be seen as an alternative to the traditional surveying techniques (LiDAR). Secondly, the article determines the input parameters for a photogrammetric flight that ensure the highest accuracy of a resulting DSM. The analyses show a strong positive correlation between the DSMs prepared based on UAV imaging with data obtained by means of traditional methods (LiDAR). Mean correlation coefficient ranged from 0.45 to 0.75 depending on the type of land use and input parameters selected for a given flight. Furthermore, the analysis revealed that DSMs prepared based on UAV imaging—provided the most suitable input parameters are selected—can be a viable alternative to standard measurements, with the added benefit of low cost and the capacity for repeatable data collection in time. Admittedly, the method in question cannot be utilized in relation to peatlands overgrown with high vegetation (trees, shrubs) as it effectively diminishes the accuracy of obtained DSMs.
