Emission Inventory for NH3, N2O, and CH4 of Animal Husbandry Activities: A case in Tho Vinh Commune, Kim Dong Distric, Hung Yen Province

Abstract

Animal husbandry contributes to emission of greenhouse gases. The aim of this study is emission inventory of greenhouse gas (NH3, N2O and CH4) from animal husbandry activities in Tho Vinh commune, Kim Dong distric, Hung Yen province. Animal population in 2015 of the commune is 1.160 of pigs, 18 of buffalos, 62 of dairy cows, 22 of beefs, 18.360 of chickens, 3.913 of ducks, and 1.357 of musk ducks. Total estimated gas emissions from animal husbandy in Tho Vinh in 2015 are NH3 (4.946 kg), N2O (812,65 kg), and CH4 (12.084,16 kg) approximatly. CH4 emmion from feed intake and cattle waste management processes from buffalo and cow are 6.568,82 kg và 5.515,34 kg respectivly. NH3 is mostly emitted by poultry (2.835,6 kg, accounted for 57%). N2O and CH4 emitted mainly from pig are 417,6 kg (51%) and 4.640 kg (31%). The highest animal population and husbandry households concentrated in Dong Hung hamlet, which results in higest gas emission.
