The Efficiency of Sequestering Carbon in Agricultural Soils
研究不同补贴和市场政策下农业土壤碳封存的预期成本，利用全国资源清单数据估算农民采用保护性耕作的概率，并结合碳封存物理模型评估补贴方案的成本。
Agricultural tillage practices are important human-induced activities that can alter carbon emissions from agricultural soils and have the potential to significantly contribute to reductions in greenhouse gas emission (Lal et al, 1998). This research investigates the expected costs of sequestering carbon in agricultural soils under different subsidy and market-based policies. Using the detailed National Resources Inventory data, we estimate the probability that farmers adopt conservation tillage practices based on a variety of exogenous characteristics and profit from conventional practices. These estimates are used with physical models of carbon sequestration to estimate the subsidy costs of achieving increased carbon sequestration with alternative subsidy schemes.
