Ensure universal access to modern energy services by 2030 2. Double the global rate of improvements in energy efficiency by 2030 3.

• 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 Northeast Arctic Cod: Stock Structure Feeding grounds Barents Sea, mature & juvenile fish Spawning grounds Norwegian coast, only mature fish © Google Earth With a catch of 400,000 tonnes per year, Northeast Arctic cod is one of the most important European fish stocks Northeast Arctic Cod: Evolutionary Change Length at 50% maturation probability at age 7 (cm) 100 Until about 1970 90 80 Today 70 1930 1970 2005 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% Fast Pace of Evolutionary Decline Eco-genetic model of Northeast Arctic cod 10 8 Today Age at maturation (years) 12 6 4 2 0 ca. 40 years Historical fishing 0 Current fishing Time (years) 100 Slow Pace of Evolutionary Recovery Eco-genetic model of Northeast Arctic cod 10 8 6 Today Age at maturation (years) 12 4 2 0 ca. 250 years Current fishing Historical fishing 0 Time (years) 100 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 0% Fraction of rich sites 100% For low temptation to defect, as in societies with strong institutional or social control, the situation reverses: full equity now maximizes cooperation 0% Fraction of rich sites 100% Social Dilemmas Common Goods and Social Dilemmas Civil security Global climate Beneficial demography Clean air Prudent urbanization Social welfare Internet Fish and game Communal land 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 Integrated Bioeconomic Model Ca. 460,000 tonnes Northeast Arctic cod 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 Adult biomass (1000 tonnes) Hilborn 2007: “Zone of New Consensus” Benefits (utility) Profit Yield Employment Zone of traditional fisheries management Zone of new consensus Ecosystem preservation 0 Fishing effort Population crash Integrated Assessment 1.
