Opportunity Cost of Precision Conservation
摘要
Abstract Conservation practices provide public environmental benefits, but the associated private costs are chiefly borne by farmers. Precision agriculture technologies can help reduce farmer private costs by identifying low-yielding areas, thereby minimizing foregone revenue. This study estimates the opportunity cost of such precision conservation on 29 commercial fields in Michigan, USA, using fine-scale yield maps collected between 2020 and 2024. We employ spatial regression models and Monte Carlo simulations to account for spatial heterogeneity and price variability. Results show that under a corn-soybean crop rotation, precision conservation improves profitability in 22 of 29 fields, indicating potential for adoption without government subsidies.

摘要 保护性耕作实践能提供公共环境效益，但相关的私人成本主要由农民承担。精准农业技术可通过识别低产区域来帮助降低农民的私人成本，从而最大限度地减少放弃的收入。本研究利用2020年至2024年间收集的精细尺度产量图，估算了美国密歇根州29块商业地块上此类精准保护性耕作的机会成本。我们采用空间回归模型和蒙特卡洛模拟来解释空间异质性和价格波动。结果表明，在玉米-大豆轮作下，精准保护性耕作提高了29块地块中22块的盈利能力，表明其具备无需政府补贴即可被采用的潜力。
