An ex post evaluation of the conservation reserve, federal crop insurance, and other government programs: program participation and soil erosion

摘要

Recent research has questioned the extent to which government policies, including conservation and risk management programs, have influenced environmental indicators. The impacts of income-supporting and risk management programs on soil erosion are considered. An econometric model of the determinants of soil erosion, program participation, conservation effort, and input usage is estimated. While the Conservation Reserve Program has reduced erosion an average of 1.02 tons per acre from 1982 to 1992,approximately half of this reduction has been offset by increased erosion resulting from government programs other than federally subsidized crop insurance.
