A Damage Function to Evaluate Erosion Control Economics
开发了一个侵蚀损害函数,用于衡量农业土壤流失的现场损害,通过动态分析比较传统耕作与保护性耕作,并应用于评估爱达荷/华盛顿帕卢斯地区小麦的少耕法。
Abstract An erosion damage function is developed to measure on‐site damage from agricultural soil loss. This method compares conventional farming and a conservation practice within a dynamic analysis treating conservation adoption year as a variable. Incremental damage from erosion, or marginal user cost, is evaluated annually and includes any cost to remedy plus lost future revenue from reduced yield. The damage function is applied to evaluate reduced tillage for wheat in the Idaho/Washington Palouse area. On shallower soils erosion damage provides conservation incentive, while on some deep soils erosion is economically rational. Properties of the damage function are explored through sensitivity analysis.
