| Abstract | Emission from biomass open burning is one of the most significant sources of greenhouse gases (GHGs) and air pollutants. This study investigated and developed an emission inventory with a temporal and spatial distribution from forest fires and crop residue open burning in Vietnam for 2010. Satellite data was used to assess the emission from forest fires, while statistic data and information from a questionnaire survey was used to assess the temporal and spatial distribution of emissions from crop residue open burning. The source of emission for biomass open burning in 2010 was predominantly burning of crop residues (80%), and forest fires (20%). Forest fire emissions were predominantly from January to April while emissions from crop residue open burning were mainly in January to February, May to June and September to October. Northwestern and Central highland provinces had the highest emission from forest fires, and provinces at Mekong River delta, Red River delta, and Central coast region had the highest emission contributions from crop residue field burning. This study determined that annual emissions from biomass open burning in Vietnam in 2010 in Gg were: 5,348 CO, 73 NOx, 7 SO2, 223 NMVOC, 118NH3, 285 PM10, 259 PM2.5,17 BC, 98 OC, 40,863 CO₂, 134 CH4 and 3.5 N2O. Total net climate forcing from biomass open burning was 73Tg CO₂-eq (20 years horizon), 50 Tg CO₂-eq (100 years horizon). A low and high emission estimation for various compounds ranged from -87% to 203% of the corresponding the best estimate value, in which SO₂, CH4 and BC had the highest uncertainties. A co-benefit analysis based on scenarios has shown that if the crop residue open burning was reduced by 50% in Vietnam then overall emission will decrease from 41% to 48% for all considered compounds, and the corresponding reduction in GWPs would be 48% over a 20 years period and 46% over a 100 years period from the 2010 base values. Further works should be conducted to provide local parameter estimates used for the production of an emission inventory. |
