Abstract
Mitigation options of CH4 and N2O emissions from agriculture can be relatively inexpensive to CO2-only mitigation.They are expected to play an important role in climate strategies.In this study, we developed an integrated model to provide along-term perspective and a quantitative basis for analyzing the GHG emissions in agriculture for 23 world regions.The main objective is to quantify the relative importance of major emissions resources.In the result, world total meat production will increase by 1.9 times from 2000 to 2030 with population growth and a gradual shift from the main staples to meat products, particularly in the developing countries.World total CH4 and N2O emissions from agriculture are 3960 MtCO2eq in 2000.They increase by 1.4 times up to 2030 mainly depending on growth of population, food production and fertilizer consumption. Large reduction potentials are estimated in developing regions such as China, , India.The options with highest economic efficiency are “Slowing down anaerobic decomposition”.
