A Case Study: the Millennium Ecosystem Assessment
A New Social Contract for Science
A Gapin perceptions of relevance and usefulness of scientific data, information & knowledge: A Gap in perceptions of relevance and usefulness of scientific data, information & knowledge Scientists:
Our knowledge is relevant & important.
Why isn’t it used?
Why isn’t it better funded?
The Gap: The Gap
Policy makers:
Scientific information: far removed from our decisions.
Results: too complex and couched in uncertainties and qualifiers.
Conclusions: ambiguous, do not provide clear guidance & ignore the complexities of policymaking.
Scientists can’t agree
Some of our constituents don’t trust your science.
Some causes of the Gap: Some causes of the Gap Different ideas about the role of science
Most scientists are not trained to translate complex science into understandable and policy-relevant information
Data and information: too much and not enough
Lack of opportunity to develop credible international scientific assessments
Lack of transparency in the production of knowledge and lack of opportunities for non-scientists to contribute to knowledge base.
Bridging the Gap:Some Possible Solutions: Bridging the Gap: Some Possible Solutions Clarify role of science
Train scientists to communicate more effectively
Organize data & information to make them more useful and relevant
Establish ongoing credible scientific assessments
Increase openness in the conduct of science and opportunities for citizens to participate in meaningful ways
Historic Roles of Science: Historic Roles of Science 1. Improve Human-Well Being
Health
Labor-saving devices
Communications
Education
Intellectual Curiosity
Assist National Defense/Security
3. Enhance National Prestige
4. Promote Economic Growth
Technology
Transportation
Another, often unappreciated role of science: To inform (not dictate)the understanding, discussions, and decisionsof individuals and institutionsand thereby improve lives and enhance human well-being : Another, often unappreciated role of science: To inform (not dictate) the understanding, discussions, and decisions of individuals and institutions and thereby improve lives and enhance human well-being
Role of science: To inform: Role of science: To inform Discover how systems work (natural, social and coupled social-natural systems)
Document changes
Understand consequences of changes
Develop and evaluate options for alternate pathways
Slide12:
If decisions are to be informed by science,
Decision-makers need to have access to scientific information that is understandable, relevant, usable and credible.
Slide13:
However, and especially for some areas like environmental science,
The science is complex, nuanced and difficult to communicate simply.
Uncertainties are real (but there is often more agreement about the basics than is communicated).
Vested interests often spin, distort or cherry-pick information.
Slide14: The Result:
1. Decisions are made without good science.
2. Science is seen as a weapon, not as useful knowledge.
Bridging the Gap:Some Possible Solutions: Bridging the Gap: Some Possible Solutions Clarify role of science: also to inform
Train scientists to communicate more effectively:
e.g. : Aldo Leopold Leadership Program (USA)
2-way communication
“Know thy audience; know thy self; know thy stuff”
Narrative; analogies; simple messages

Conclusions: Conclusions The Gap can be Bridged, but doing so requires effort by scientists and by society.
Scientists can and should actively work to build these bridges, but they must be done in partnership with governments and civil society

The Millennium Ecosystem Assessment (MA): The Millennium Ecosystem Assessment (MA) A global scientific assessment of:
the consequences of environmental changes
to human well-being
status of global ecosystem services
options for change
Released 2005, 2006

Slide24: “Ecosystem Services”
= Benefits provided by ecosystems
Slide25: Converting an ecosystem means losing
some services and gaining others – e.g.,
A mangrove ecosystem: Provides nursery and adult habitat ,
Seafood, fuelwood, & timber;
traps sediment; detoxifies pollutants;
protects coastline from erosion & disaster
Slide26: Converting a mangrove to provide housing,
shrimp ponds or agricultural areas, means
Losing some services and gaining others Or crops Shrimp, Gain: housing, Loose: nursery and adult habitat ,
Seafood, fuelwood, & timber;
traps sediment; detoxifies pollutants;
protects coastline from erosion & disaster
Slide27: Many ecosystem services are quite valuable, but are not priced. Example: The Catskill Watershed provides drinking water to the city of New York water purification
is one
ecosystem service
provided by this forest
Slide28: Options: 1) Restore the watershed so it could resume providing this service of water purification = $1 billion
Slide29: Options: 1) Restore the watershed so it could resume providing this service of water purification = $1 billion OR 2) Build a water purification plant (i.e., build a human-made substitute) = $8-10 billion
Slide30: “You don’t know what you’ve got
‘til it’s gone.”
(Joni Mitchell)
Slide31: 4 Types of Ecosystem Services Regulating
climate regulation
disease regulation
flood regulation
water purification Provisioning
• food
• fresh water
• fuel wood
• genetic resources Cultural
• spiritual
• recreational
• aesthetic
• educational

Slide33: 1. Humans have radically altered ecosystems in last 50 years Changes have brought gains but at growing costs that threaten achievement of development goals
Degradation of ecosystems could grow worse but can be reversed Workable solutions will require
significant changes in policy Main Findings

Slide37: Mangrove Conversion Private Net Present Value per hectare
Mangrove: $91
Shrimp Farm: $2000 1987 1999 Public Net Present Value per hectare
Mangrove: $1,000 to $3,600
Shrimp Farm: $-5,400 to $200
The main messages of the MA: The main messages of the MA We are having increasingly larger impacts on ecosystems and their services
Many segments of society have benefited from the mining of ecosystem services but the sustainability of these services is at risk
Scenarios of the future show do not show substantial abatement of degradation
We have options to build more favorable trajectories, but these will take substantial new actions
The MA Bottom Line: The MA Bottom Line We are spending Earth’s natural capital, putting such strain on the natural functions of Earth that the ability of the planet’s ecosystems to sustain future generations can no longer be taken for granted.
The future is in our hands. We can reverse the degradation of many ecosystem services over the next 50 years, but many changes in policy and practice will be required.
Example: global ocean trends: Example: global ocean trends Depletion of ocean ecosystems
Loss of resilience (increased likelihood of abrupt changes)
“The times they are a changin’…Today we fish- farther and farther from shore,- deeper and deeper,- more efficiently,- more safely,- and in formerly inaccessible places: “The times they are a changin’… Today we fish - farther and farther from shore, - deeper and deeper, - more efficiently, - more safely, - and in formerly inaccessible places

The Result:Empty OceansEmpty Nets: The Result: Empty Oceans Empty Nets
Biological Causes of Declines: Biological Causes of Declines Rate of Fishing > rate of replenishment
Selective catch of big old fat female fish (BOFFF) undermines replenishment
Unintended ecosystem impacts of fishing: habitat destruction & by-catch
Cumulative and interactive effects of fishing, pollution, coastal development, upstream activities, climate change
What’s Down the Road?: What’s Down the Road? More of the same unless underlying problems are addressed
(overfishing + coastal development + chemical and nutrient pollution + climate change)
A vision for the future:: A vision for the future: Healthy seafood
Clean beaches
Stable fisheries
Abundant wildlife
Vibrant coastal communities
For now and future generations
Key recommendations to achieve vision: Key recommendations to achieve vision Protect and restore ecosystems
Improve fishery management & implement ecosystem-based management
Establish networks of marine reserves
Couple management of land and sea
Educate citizens
Invest in research and monitoring
Historical Note: Historical Note Until very recently, the
ocean was replete with
de facto marine reserves
– areas where it was:
too far away,
too deep, or
too rocky to fish.
Now, < 1% is in reserves
Slide53: Changes inside Marine Reserves: - From Halpern ‘03
and Palumbi ‘03 Species are
more abundant,
larger and
more diverse
inside reserves.
Slide54: Size matters:
A 40 cm vermilion rockfish produces
150,000 young,
whereas a 60cm one produces 1.7 million young 40cm 60cm = 100,000 babies 50 cm
Marine Reserve Conclusions:Potential to Benefit both Conservation & Fishery Management: Marine Reserve Conclusions: Potential to Benefit both Conservation & Fishery Management Protect Habitats, Species and Ecosystem Functioning
Provide Spill over of juveniles & adults
Provide Export of larvae
Protect big old fat female fish (BOFFF)
Provide insurance against mismanagement or environmental changes
Serve as scientific reference areas
