This study examined the environmental benefits of pesticide risk reduction in Ontario, Canada, and determined that the reduction in external costs associated with changes in pesticide use between 1983 and 1998 was $188 per household and $711 million (in US dollars) for the province as a whole. These benefits were largely due to the reduction in the levels of high and moderate-risk pesticides.

  • values of the changes in environmental risks posed by pesticides

Potential Benefits: (Not available)


  • Ontario, Canada

Models Used: (Not available)

Methods Used:

  • The authors evaluated the value of environmental benefits associated with changes in the levels and types of pesticides applied in Ontario agriculture. They used the physical risk assessment approach (Mullen et al. 1997) with an incorporated contingent valuation survey to determine consumers' willingness to pay (CWP) for reductions in pesticide risk to different components of the environment. Using this approach, the authors — 1) identified changes in pesticide risk to the environment; and 2) examined valuation of changes in environmental risk using previous estimates of respondents willingness to pay (WTP) to reduce risk within each environmental category.

Sources Used:
