ABSTRACT


The degradation of peatlands through anthropogenic activities recently has contributed to low carbon uptake from the air. Peatlands are one of the largest sources of CH4 (methane) emissions in terrestrial ecosystems, but during the COVID-19 pandemic with restriction policy was applied, it can affect the atmospheric CH4 concentration and change the atmospheric greenhouse gases. In Indonesia, the lockdown policy was known as the Large-Scale Social Restriction (LSSR) that was implemented in high COVID-19 case areas. In this study, the atmospheric CH4 concentration over the tropical peatlands in the South Sumatera Province of Indonesia was examined at three different periods such as before the COVID-19 pandemic (March and May 2019), before LSSR (March 2020), and during LSSR (May 2020). The CH4 concentration was measured using Atmospheric Infrared Sounder (AIRS) on NASA's Aqua Satellite, while the Gross Primary Production (GPP) was measured by the NASA’s Moderate-resolution Imaging Spectroradiometer (MODIS) aboard the Terra Satellite. The results of the study revealed the average atmospheric CH4 concentration over the South Sumatera Peatland was about 1.73 ppm, which decreased by 5.5% during the LSSR period. Furthermore, GPP values were observed ranging from 53.3 to 63.9 g C m-2 day-1 during the LSSR which indicated high carbon uptake from the atmosphere. In conclusion, the LSSR application has significantly influenced the atmospheric CH4 over the peatlands through restriction of human activities such as land-use conversion, biomass burning, forest fire and etc.
