Estimation of land cover changes and biomass carbon stock in north-eastern hill forests of Bangladesh

Forests are atmospheric CO2 sinks, but their losses and degradation accelerate the emissions of carbon stored as a sink. Deforestation forest widespread in Bangladesh, impact on greenhouse gas (GHG) is unknown. We assess land use cover (LULC) change loss this study by classifying different Landsat satellite imagery with focus from 1989 to 2020. Tier 1 standards were used estimate removal small-scale tropical forest. Over last three decades, area has decreased 2.40%, 3.74% 7.52%, respectively. The primary causes large-scale tea garden homestead expansion, as well increase agricultural activities. Because of reduction area, annual gain biomass also decreased. Although overall emission was net for Maulvibazar hill forest, it 331.24 Gg·yr–1 first decade (1989 2000) 307.7 the most recent (2011 2020), which an alarming trend. As result, research will contribute leaders’ commitment “halt reverse 2030” at 26th United Nations Climate Change Conference Parties (COP 26) 2021 improve sequestration, combat climate conserve biodiversity.
