An economic evaluation of the environmental benefits from pesticide reduction
结合物理风险评估和消费者支付意愿调查，评估了1983至1998年间安大略省农业减少农药使用带来的环境效益，每户家庭减少外部成本188美元。
Abstract Previous studies on the environmental impacts of pesticide use have tended to focus either on measuring damages through changes in relative risks to various environmental categories or examining the trade‐off between pesticide use levels and abatement costs. This study uses the physical risk assessment approach combined with contingent valuation survey results on consumers’ willingness to reduce pesticide risk. The reduction in external costs associated with the changes in pesticide use in Ontario agriculture between 1983 and 1998 is U© 188 per household. The environmental benefits are largely due to the reduction in the level of high and moderate‐risk pesticides.
