Define ”ecosystem approach”!

Enter the word ”integrate”
Integrated monitoring and surveys
Integrate science into management advice
Integrate across disciplines
Integrate across sectors
![Page 9: Exploiting the goldmine of acoustics for integrated ecosystem assessments](https://reader034.fdocuments.net/reader034/viewer/2022042818/55b22e2ebb61ebb4268b46bf/html5/thumbnails/9.jpg)
Operational - ”integrate”
1. Focus on relationships & processes within ecosystem2. Enhance benefit-sharing3. Use adaptive management practices4. Carry out management actions at the scale
appropriate for the issue, with decentralization.5. Ensure intersectoral cooperation.

Searching for the golden fleece?
Problem is not understood until after the formulation of solution

We use knowledge

Veracity of evidence
Evidence of differing integrity, sources & certainty.
Learn to integrate the more certain with the less certain, combine across management objectives and show tradeoffs

Solution clear – set a target
Operational indicators for management

Are all anthropogenic pressures so clear?
• often insufficient evidence to define targets & support assessment of state
• links to anthropogenic pressures are weak or not sufficiently well understood to underpin specific management advice
![Page 28: Exploiting the goldmine of acoustics for integrated ecosystem assessments](https://reader034.fdocuments.net/reader034/viewer/2022042818/55b22e2ebb61ebb4268b46bf/html5/thumbnails/28.jpg)
What pressures impact?
Can we set targets?
![Page 29: Exploiting the goldmine of acoustics for integrated ecosystem assessments](https://reader034.fdocuments.net/reader034/viewer/2022042818/55b22e2ebb61ebb4268b46bf/html5/thumbnails/29.jpg)
Surveillance indicators
Not expected to directly track state in response to changes in pressure,
Provide complementary information (including warning signals) that informs and supports science, policy and management.
![Page 30: Exploiting the goldmine of acoustics for integrated ecosystem assessments](https://reader034.fdocuments.net/reader034/viewer/2022042818/55b22e2ebb61ebb4268b46bf/html5/thumbnails/30.jpg)
Risk based approach
Not monitoring for monitoring sake
Carefully targeted surveillance
Need to link to management objectives
Set bounds that trigger action

Visiting a gold mine of data and knowledge
ACOUSTICS

So back to my title:
Tips for acoustic scientists on exploiting the gold mine: integrated ecosystem assessments.
![Page 35: Exploiting the goldmine of acoustics for integrated ecosystem assessments](https://reader034.fdocuments.net/reader034/viewer/2022042818/55b22e2ebb61ebb4268b46bf/html5/thumbnails/35.jpg)
IEAs are greedy for knowledge
We help provide the evidence base to inform management decisions.Improving and sharpening that evidence is important
but it is not the whole story
![Page 36: Exploiting the goldmine of acoustics for integrated ecosystem assessments](https://reader034.fdocuments.net/reader034/viewer/2022042818/55b22e2ebb61ebb4268b46bf/html5/thumbnails/36.jpg)
Important transfer of acoustic expertise
Expertise in combining data from different sources
Integrating new technologies
Integrating space and time into analysis
Importance of behaviour and interactions
![Page 37: Exploiting the goldmine of acoustics for integrated ecosystem assessments](https://reader034.fdocuments.net/reader034/viewer/2022042818/55b22e2ebb61ebb4268b46bf/html5/thumbnails/37.jpg)
From science to IEAs
Learn to talk across disciplines- build common language
Integrate work with partners and stakeholders
Practice creating simple messages
Data aids but is not knowledge
Remember it is WICKED!
