GLOBAL ENERGY ASSESSMENT
• Launched in 2012 at Rio +20 Summit
• Outcomes include defining the aspirational yet
feasible objectives for the UN SecretaryGeneral’s Sustainable Energy For All Initiative:
1. Ensure universal access to modern
energy services by 2030
2. Double the global rate of improvements in
energy efficiency by 2030
3. Double the share of renewable energy in
the global energy mix by 2030

Rapid
Adaptation
Two Types of Adaptation
• Biological evolution
operates through genetic change (slower)
• Cultural evolution
operates through social learning (faster)
Two Common Misperceptions
• Biological evolution is always slow
On the contrary, rapid contemporary evolution is
widespread, in particular in response to
anthropogenic environmental change
• Biological evolution is always optimizing
On the contrary, selection operates at the individual
level, implying that population-level features will rarely
get optimized by evolution
Example: Modern Fisheries
• Evolutionary responses of stocks to modern
fishing pressures are inevitable
• Significant evolution can occur within just a
few generations
• Evolutionary changes are not necessarily
beneficial
• Evolutionary changes will often be difficult to
reverse
Which Traits Are at Risk?
• Age and size at maturation
 Reproducing late is impossible
• Reproductive effort
 Saving for future seasons is futile
• Growth rate
 Staying below mesh size prolongs life
• Morphology and behavior
 Avoiding fishing gear is advantageous

With a catch of 400,000 tonnes per year, Northeast Arctic cod is
one of the most important European fish stocks

This shift in maturation schedule contributes to a drop in
maturation age from 9-10 years to 6-7 years and reduces initial
egg production by about 50%

Interdependent
Agents
A few rich cooperators suffice to enable
cooperation under adverse conditions
With wealth inequality
Without wealth inequality
Blue: cooperators, red: defectors, bright: rich sites, dark: poor sites
Social planners can maximize cooperation by
managing wealth inequality
Contrast between rich and poor sites
High temptation to defect
Low temptation to defect
Planners can move along
iso-wealth curves to
maximize cooperation
Making just 10% of sites
3 times richer greatly
improves cooperation

Garrett Hardin
Open-access resources that are
utilized unrestrictedly tend to
suffer from overexploitation and
will often collapse through a
‘tragedy of the commons’, in
which the selfish actions of
individuals jeopardize a common
good
Framing the Social Dilemma
• Conventional (‘Tragedy of the Commons’)
– Foster cooperation despite selfish behavior
– Emergence of social institutions
– Insights from game theory
• Broadened framing
– Account for plural rationalities
– Emergence of socially inclusive institutions
– Insights from cultural theory
Inclusive Governance
• Recognizes stakeholder views, and therefore
accounts for their heterogeneity in terms of age,
sex, income, race, interests…
• According to cultural theory, it is critical to also
account for worldviews:
–
–
–
–
Individualism (choice, markets)
Egalitarianism (moral stance, communal)
Hierarchism (control, regulation)
Fatalism (life is a lottery)
Stakeholder
Diversity
Approaches for Social Planners
When agents are heterogeneous, social planners can
• Analyze stakeholder impacts
• Optimize for one stakeholder or objective
• Optimize across stakeholders or objectives
• Promote compromise across stakeholders

Derived Harvest Control Rules
 Harvest-control rules are politically
negotiated without support from
quantitative modeling
 Our assessment is process-based,
couples an individual-based
biological model with an economic
model, and accounts for three
alternative objectives
 Current rule maximizes profit,
Yield-maximizing HCR
(Johannesburg World
Summit 2002)
Welfare-maximizing HCR
Current HCR
Profit-maximizing HCR
while alternative objectives lead to
more aggressive exploitation

A propos:
The Anthropocene
• For the first time in the Earth’s history are the major
processes dominated by a single species:
• Homo (not-so much) -sapiens ?
• The current era is therefore so unique that is has been
labeled the ‘Anthropocene’
• What are the consequences and can we manage
this?
