CALCULATING GREEN HOUSE GAS EMISSIONS (CH_4, N_2O, CO_2) RELEASED FROM AGRICULTURE - A CASE STUDY IN DONG THAP PROVINCE

摘要

Agriculture sector accounted about 33% of total greenhouse gas emissions, ranked second after energy. In Vietnam, agriculture plays a vital role in the economic development contributing 18.14% to the GDP of Vietnam in 2016 with average growth accelerator approximately 4.06% per year from 1986 to 2015. The case study is Dong Thap province which was ranked the third in producing rice (3,397 million tons /year, 2016) and the second in aquatic products in Vietnam. This article presents results of the GHG emissions assessment from agricultural activities in the cultivation (rice, maize, sweet potato) and biomass burning, aquaculture and livestock (manure management, enteric fermentation) by utilizing IPCC method (IPCC, 2006). The results show that CO2 emissions from crops accounted for the highest rate (57.22%), followed by the combustion of agricultural straw burning (41.1%). While that of livestock and aquaculture figure reach 1.28% and 0.39%, respectively.
