Estimation of greenhouse gases in rice fields and plantations in Teluk Bintuni Regency, West Papua

Abstract The study purpose was to estimate greenhouse gases produced in agricultural sector in Teluk Bintuni Regency. Data were taken from 15 farmer groups from 15 districts, and 6 families of rice farmers assisted by Tangguh LNG’ CSR. The calculation method uses IPCC 2006 Tier 2. The correction fac...

Summary:Abstract The study purpose was to estimate greenhouse gases produced in agricultural sector in Teluk Bintuni Regency. Data were taken from 15 farmer groups from 15 districts, and 6 families of rice farmers assisted by Tangguh LNG’ CSR. The calculation method uses IPCC 2006 Tier 2. The correction factor used in calculating Bintuni’s GHG is adjusted based on land area, soil type, type of fertilizer, and type of irrigation used. The results show that paddy farming activities by rice farmers assisted by Tangguh LNG CSR produce CH 4 of 964.45 kg/year, or CO 2 of 20.253,54 kg/year. Fertilization activities on paddy fields produced direct emissions of 1344.51 kg CO 2 , indirect emissions of 436.97kg CO 2 , fertilizing activities of paddy fields using NPK produced direct NO 2 emissions equivalent to 456.70 kg CO 2 , and indirect emissions of 148.43 kg CO 2 . Fertilization activities on plantation land using ZA fertilizer produced direct NO 2 emissions of 2969.74 kg CO 2 and indirect emissions of 965.165 kg CO 2 , NO 2 emissions from NPK fertilizer produced direct emissions of 6074.467 and indirect emissions of 1974.20 kg CO 2 . It is necessary to further implement low-emission agricultural activities through fertilization of the right size and selection of rice varieties and low-emission irrigation systems.
