研究了覆盖作物相比非覆盖作物在碳封存和温室气体减排方面的影子价格,发现每英亩分别价值17.88美元和9.42美元,并与激励计划支付对比,揭示可持续农业实践的经济可行性和障碍。

Abstract

Abstract We derive shadow prices of carbon services provided by cover crops relative to non‐cover‐crop agricultural practices, accounting for carbon sequestration and greenhouse gas (GHG) emissions. We model the agricultural technology by integrating crop production, carbon sequestration, and GHG emissions. We derive a novel function representation of our technology using a data envelopment analysis (DEA). We then calculate shadow prices based on the dual representation of the technology and compare shadow prices between cover‐crop and non‐cover‐crop fields. We find that the carbon sequestration and the GHG emissions reduction services from cover‐crop fields relative to non‐cover‐crop fields are worth USD 17.88 and USD 9.42 per acre, respectively. We compare shadow prices to payments from an incentive program aimed at promoting cover‐crop adoption, thereby highlighting the economic feasibility and potential barriers to adopting sustainable practices.
