 Intégrer l'agriculture dans les politiques d'atténuation chinoisesWen Wang in Economics Thesis from University Paris Dauphine from Paris Dauphine University Abstract: This thesis is an evaluation of the overall technical and economic mitigation potential in China agriculture and the conditions of putting a carbon price in this sector. The research scope is cropland emissions and particularly those related to synthetic nitrogen fertilizer use. The thesis is articulated around the construction of a bottom-up marginal abatement cost curve (MACC) which offers a rational framework for combining biophysical and economic data to reflect mitigation costs. This tool allows the aggregation of the mitigation potential arising from the application of a subset of cost-effective measures above a notional baseline level. An analysis of Chinese climate policies reveals that agriculture is nearly absent in the current national mitigation strategy. We therefore intend to assess the technical, economic and political feasibility of integrating agriculture into domestic mitigation policies. In the first place, the emissions trends and calculation methods are assessed to determine a rigorous approach to build baseline scenarios from projected business-as-usual activities to 2020. Secondly, we identify nine cropland mitigation measures, evaluate their abatement rates and future applicability beyond the baseline scenario to conclude a total feasible technical mitigation potential. The translation to the economic potential is then made by comparing the implementation costs of different mitigation options relative to conventional farming practices. The MACC results show that agriculture provides significant mitigation potential to be able to offset about one-third of baseline emissions and realisation of one-third of the potential is cost-negative for farmers. We finally examine the conditions of using economic instruments to reduce emissions at the lowest cost for the agricultural sector. Given the institutional, behaviour and socials obstacles, we strongly suggest a reform in agriculture fertilizer subsidies to send a clear political signal from central planning. Scaling-up offset projects using carbon intensity as the standardized baseline is recommended and can prepare the grounds for a possible experimental emission trading programme in agriculture. In light with the top priority of safeguarding food security in China, cases studies on regional cereal production are carried out in all these steps, including the analysis of provincial greenhouse gas intensity of production, regional abatement potential related to synthetic nitrogen fertilizer use as well as implementation cost disparities in certain regions.
