A STUDY ON GREENHOUSE GAS EMISSIONS AND MITIGATION POTENTIALS IN AGRICULRE

Abstract

 In this study, world food production and consumption are estimated from 2005 to 2030 using a model developed by General-to-specific modeling methodology. Based on the agricultural production, we estimated GHG emissions and mitigation potentials and evaluated mitigation countermeasures in agriculture. As a result, world crop and meat production will increase by 1.4 and 1.3 times respectively up to 2030. World GHG emissions from agriculture were 5.7 GtCO₂eq in 2005. CH₄ emission from enteric fermentation and N₂O emission from nitrogen fertilizer contributed a large part of the emissions. In 2030, technical and economical mitigation potentials will be 2.0 GtCO₂eq and 1.2 GtCO₂eq respectively. The potentials correspond to 36% and 22% of total emissions in 2000. The countermeasures with highest effects will be water management in rice paddy such as "Midseason drainage" and "Off-season straw".
