Integrating Science and Policy:

The role of science in decision-making

science vs management
Science vs Management

Science involves:

Management involves:

  • Very narrow questions
  • Few variables
  • Controlled experimental conditions
  • None of these

Management Decisions

3

the management niche
The management “niche”

An n-dimensional hypervolumebounded by the limits of tolerance to science, law, and policy considerations (with apologies to G. Evelyn Hutchinson)

4

influencing policy
Influencing policy
  • We can be wrong: Interesting to scientists, death to policy making
  • We disagree: Challenge and debate are essential to good science; lack of consensus confuses policy making
  • We are uncertain: Nature of the beast, but difficult to accommodate in policymaking

5

which what whose science

Different technical disciplines – “If your only tool is a hammer, every problem looks like a nail”

    • Population dynamics
    • Ecology
    • Hydrology
    • Genetics
    • Nutrition/fish health
  • Traditional ecological knowledge – tribal cultural perspectives
  • Which is “best available”?
Which, what, whose science?

demographics density effects crowding competition predation lower survival
Demographics“Density effects” Crowding + Competition + Predation = lower survival

OR

Genetics?

“Hatchery effects”

Genetic selection

- Altered behavior

- Fitness loss

= lower survival

Policy considerations:

  • Correct diagnosis of the problem?
  • What level of confidence?
  • Appropriate remedies
  • Risk structure: How are the risks and benefits distributed?
  • Does the evidence indicate that a change in policy is warranted or prudent?
