THE POTENTIAL OF U.S. AGRICULTURE AND FORESTRY TO MITIGATE GREENHOUSE GAS EMISSIONS: AN AGRICULTURAL SECTOR ANALYSIS
用数学规划模型分析美国农业和林业中多种温室气体减排策略的经济潜力，考察不同碳价下策略组合的变化，包括土壤、牲畜、造林和生物燃料等选项，并评估市场影响和福利分配。
Mathematical programming is used to examine the economic potential of greenhouse gas mitigation strategies in U.S. agriculture and forestry. Mitigation practices are entered into a spatially differentiated sector model and are jointly assessed with conventional agricultural production. Competition among practices is examined under a wide range of hypothetical carbon prices. Simulation results demonstrate a changing portfolio of mitigation strategies across carbon prices. For lower prices, preferred strategies involve soil and livestock options; higher prices, however, promote mainly afforestation and biofuel generation. Results demonstrate the sensitivity of individual strategy potentials to assumptions about alternative opportunities. Assessed impacts also include market shifts, regional strategy diversity, welfare distribution, and environmental co-effects.
