Metamodelling phosphorus best management practices for policy use: a frontier approach
开发了一个建模系统,用于综合农业耕地中异质的生产力和养分负荷潜力,以支持政策制定。通过前沿分析对明尼苏达州东南部流域的磷削减成本函数进行元建模,评估减少非点源磷排放的政策效果。
This article presents a modelling system for synthesising heterogeneous productivity and nutrient loading potentials inherent in agricultural cropland for policy use. Phosphorus abatement cost functions for cropland farmers in a southeastern Minnesota watershed are metamodelled using frontier analysis. These functions are used to evaluate policies aimed at reducing nonpoint phosphorus discharges into the Minnesota River. Results indicate an efficiently targeted policy to reduce phosphorus discharge by 40% would cost US$167,700 or 844 per farm.
