The Reduction Policy Analysis Of China Non-Co₂ Greenhouse Gas From Agriculture

The global warming caused by increasing in greenhouse gas emissions and therefore the reduction policies for global greenhouse gas emission are not only an environmental and technology issues, but also a complex social and economic problems.Therefore, how to find a cost-effective way to reduce greenhouse gas emissions and how to adopt the effective reduction policy in a wide range is an important subject for study.The impact of agricultural Non-CO2 greenhouse gas on climate change can not be ignored. The 4th Assessment Report of Intergovernmental Panel on Climate Change shows that agriculture is the main source of greenhouse gases. It is estimated that worldwide agricultural CH4 emissions accounts for 50%r the total CH4 emissions due to human activity, N2O accounts for 60%. If the additional agricultural policy is not implemented, To 2030, agricultural methane and nitrous oxide emissions will increase by 60% and 35% to 60% compared to 2005, therefore, study of reduction of agricultural Non-CO2 greenhouse gas has an important role in the control of global climate change.This study was based on the above objective. Firstly we construct the general equilibrium model for agricultural Non-CO2 greenhouse gas, which provides analysis platform for the reduction of agricultural Non-CO2 greenhouse gas. Then, we build the database of agricultural Non-CO2 greenhouse gas in China from 2004 to 2009.Based on the above data and model, this study makes a series of general equilibrium analysis for the agricultural Non-CO2 greenhouse gas. First of all, we predict the agricultural Non-CO2 greenhouse gas in China from 2010 to 2020, and then we use the general equilibrium model to analyse the carbon tax policy with livestock methane emissions carbon tax as an example,which aims to simulate the effects of reduction and economy impact of the economic policy of the agricultural Non-CO2 greenhouse gas. Finally, we use the general equilibrium model to analyse the nitrogen fertilizer application improvement policy to simulate the effects of reduction and economy impact of the technology policy of the agricultural Non-CO2 greenhouse gas.We get conclusions based on the simulation of the agricultural Non-CO2 greenhouse gas reduction:1.The agricultural Non-CO2 greenhouse gas emission in Chian can not be ignored, especially the livestock methane emissions and nitrous oxide emissions from farmland grow significantly in the future.2. The action for the reduction of the agricultural Non-CO2 greenhouse gas can produce a quick effect, which will boost the progress in curbing climate warming.3. The application of carbon tax on livestock Non-CO2 greenhouse gas emissions will play a better result, but it will have some negative impact on the development of animal husbandry in China.4. The carbon tax on agricultural Non-CO2 greenhouse gas emissions should not be too high, low and moderate carbon tax can not only play a higher effect, but slso not impose excessive costs on the agriculture.5. Improving technology on the application of nitrogen fertilizer in China can not only reduce agricultural pollution of water resources, but also effectively reduced agricultural greenhouse gas emissions of nitrous oxide. What's more, it can promote the economic development of various sectors and macro economy.Finally, based on the conclusions and the agriculture actual production condition, we propose the recommendations of this article:1.Increasing publicity of the reducyion of the agricultural Non-CO2 greenhouse gas emission, raising the attention levels of government and farmers.2. Making a full use of the benefits of agricultural policies, financial support to promote low-carbon agriculture development.3. For the reduction of the agricultural Non-CO2 greenhouse gas emission, a different emission reduction measures should be taken for different types of agricultural Non-CO2 greenhouse gas.4. Under current conditions, Technology emissions reduction should be the main measures for the agricultural Non-CO2 greenhouse gas emission.5. To strengthen technical guidance to farmers, to improve the utilization efficiency of agricultural inputs.
