Exploring regional variations in agricultural greenhouse gas emissions: Insights from Bangladesh’s districts
Agriculture is part of the food production that feeds the expanding population though it produces considerable greenhouse gas (GHG) emissions. It’s crucial to balancing food security and emission reduction for a win-win scenario. However, the lack of sufficient comprehensive district-level assessments makes it difficult to determine the specific mitigation potential for agriculture emissions. In this study, we deployed the IPCC Tier 1 approach and estimated GHG at district/division level in Bangladesh from the year 2010 to 2021. We computed three primary GHG (CO2, N2O, and CH4) from five sources of agriculture, namely, rice-growing CH4, other crops-growing N2O, enteric fermentation, urea fertilizer-induced N2O, and energy-related CO2 emissions in the 64 districts, and aggregated them into eight divisions. We observed from this study that GHG emissions in Bangladesh gradually increased from 2010 to 2021 and reached the peak (34.3 MtCO2e) in 2021. Rangpur division emitted the highest amount of GHG (6.03 MtCO2e in 2021) during this period. We also observed significant variations in the sources and structure of emissions within each division. Moreover, regional differences were observed in overall emissions and per capita emissions after additional spatial analysis, with per capita GHG emissions declining from 2010 (1.97 tCO2e) to 2021 (1.90 tCO2e). Findings of this regional (district/division) estimation will help stakeholders of the country to develop suitable mitigation approaches which targets particular emission sources and geographic areas.
