Thousands of studies deal with technical, health and environmental issues Hundreds deal with the problem from economic or management perspectives Some deal with the perception of risks Very few focus on the policy process

Research shows that the effectiveness of a policy hinges on its ability to: 1.  2.  3.  44. .

Describe clear, attainable goals Specify what the problem is Develop an objectives hierarchy Utilize a transparent process

Land-application regulations in British Columbia, Canada and Sweden •  What are the objectives? •  How are the objectives prioritized (objectives hierarchy)? •  Is the process transparent?

What did we find?

But .... … it’s unclear what this means in practice What are the priorities? How are trade-offs made?

Core objectives are similar and clear: •  • 

Minimize risks for humans and the environment Encourage correct/beneficial use

Goals

… we managed to figure them out but not very clear

Recap: The effectiveness of a policy hinges on its ability to 1.  Describe clear, attainable goals 2.  Specify what the problem is 3.  Develop an objectives hierarchy 4.  Utilize a transparent process

•  Clear and attainable goals? •  Is the hierarchy clear?

Nope..

•  Is the hierarchy clear?

The effectiveness of a policy hinges on its ability to 1.  Describe clear, attainable goals 2.  Specify what the problem is 3.  Develop an objectives hierarchy 4.  Utilize a transparent process

… and the basis for assessing one as more problem as more important than another is hidden in darkness....

The effectiveness of a policy hinges on its ability to 1.  Describe clear, attainable goals 2.  Specify what the problem is 3.  Develop an objectives hierarchy 4.  Utilize a transparent process

•  Transparent and clear objectives? •  Is the hierarchy clear?
