Abstract

This paper describes an estimation method to develop an emission accounting table of global agricultural activities which consists of accounting tables including agricultural commodity flows from production to consumption, GHG emissions and agricultural waste etc.. Material and monetary flows related with agricultural commodities are estimated by using reported information such as production, trade and cosumption from published statistics. In our calculation, the table covers 94 countries and 12 regions in the world from 1971 to 2000. These calculations are conducted to extract most plausible estimates which minimize differences between estimated data and reported data subjected to several constraints on the accounting systems. In our estimation, 47.4% and 72.2% of all estimated values are in 0.95-1.05% range and 0.80-1.20% range of reported value, respectvely. We found a part of outliers in the existing data was modified. We clarified that total CH4 and N2O emission is estimated to have been 2450 MtCO2eq and 131 MtCO2eq in 1971 and they are estimated to have increased to 3140 MtCO2eq and 2220 MtCO2eq in 2000.
