The Utility of Sentinel-2 Spectral Data in Quantifying Above-Ground Carbon Stock in an Urban Reforested Landscape

Abstract: The transformation of the natural landscape into an impervious surface due to urbanization has often been considered an important driver of environmental change, affecting essential urban ecological processes and ecosystem services. Continuous forest degradation and deforestation due to urbanization have led to an increase in atmospheric carbon emissions, risks, and impacts associated with climate change within urban landscapes and beyond them. Hence, urban reforestation has become a reliable long-term alterna… Show more

“…As urban trees have different surroundings in terms of space, light and nutrients that natural forest, variation in biomass is multiplied by a conversion factor of 0.8 (Dangulla et al, 2021;Lahoti et al, 2020). Tree carbon storage capacity was evaluated using biomass values and a carbon default value of 0.50 (Mngadi et al, 2021;Shen et al, 2020). Afterwards, in order to produce CO 2 equivalent (CO 2 eq), the amount of carbon present was multiplied by 3.67, the ratio of the molecular weight of carbon dioxide to the atomic weight of carbon (Amiri et al, 2020).…”

“…This research discovered that Sentinel 2 imagery can be used to estimate mangroves carbon stock up to 61%. Meanwhile, Mngadi et al (2021) implemented a random forest model to Sentinel 2 imagery to predict urban reforested carbon stock in South Africa and yielded an accuracy of 79.82 and an RMSE between 0.38 -0.47 t/Ha. Sentinel 2 imagery data combines its resolutions, namely spatial, temporal, and spectral better than other optical datasets (Ghosh et al, 2021).…”

“…In [13], the authors attempted to examine the prospects of Sentinel-2 spectral data for quantifying the carbon stock in a reforested urban landscape, using Random Forest and, as predictors, 10 Sentinel bands plus 15 spectral indices that summarise the spectral content without taking into account in any way the spatial correlations typical of an image. Similarly, in [10] the authors applied Sentinel-2 satellite images combined with field-measured biomass using Random Forest (RF) to estimate above-ground biomass (AGB) in Yok Don National Park, Vietnam.…”
