Abstract:
This research had two objectives. The first objective was to quantity the carbon emissions from fires of various
types of tropical wetland vegetation using Sentinel-2 imagery. The second objective was to measure how long
the carbon stock will recover using Sentinel-2 imagery. Burned areas were extracted automatically using the
Relativized Burn Ratio (RBR). Calculation of carbon emissions and carbon sequestrations were carried out by
measuring the differences in Above Ground Biomass (AGB) before the fires, right after the fires, and a few
months after the vegetation re-grows after the fires. Therefore, multitemporal Sentinel-2 MSI imageries from
three different times are required. All imageries processing was carried out using the ESA SNAP software. The
results showed that tropical wetland fires emited an average of 121.61 Mg C/ha, or equivalent to 445.9 Mg
CO2/ha. Furthermore, tropical wetlands had an average rate of about 9.27 months to restore their carbon stocks
to their pre-burnt state. Peatland forests took the longest time to recover to its original carbon stock state after
burning, which was almost 22 years to recover.
