Abstract:

Using life cycle assessment (LCA)methods,animal husbandry carbon emissions in 31 provinces of China from 2000-2014 were measured and spatial and temporal characteristics revealed. Using dynamic panel data model (GMM),the interaction mechanisms between animal husbandry carbon emissions,per capita net income of rural residents (PCNIRR),per capita disposable income of urban residents (PCDIUR)and urbanization were also analyzed. We found that from 2000 to 2014,the total amount of animal husbandry carbon emissions in China increased from 126.936 million tons to 131.335 million tons,with average annual growth rate of 0.244%,of which gastrointestinal fermentation of livestock and manure management systems carbon emissions were the two main sources,accounting for 74.14%~79.67% of total animal husbandry carbon emissions. During the study period,China's high and low animal husbandry carbon emissions areas were relatively stable,while slightly high and moderate animal husbandry carbon emission areas showed clear dynamic evolution. High animal husbandry carbon emissions areas were mostly located in prairie areas or major grain producing areas of China,and the top 10 animal husbandry carbon emissions provinces accounted for 57.50% of the total animal husbandry carbon emissions in China. During 2000-2007,prairie pastoral areas were increasingly the center of animal husbandry carbon emissions,however this shifted to farming pastoral areas from 2007-2014. The coefficients of PCNIRR,PCDIUR and urbanization to animal husbandry carbon emission were 0.078,0.127 and -0.145,respectively,meaning that interactions between these three factors will determine future temporal and spatial evolution patterns of animal husbandry carbon emission growth in China.
