14. We need social theories to understand human-environment interactions • Survey Moran, “Environmental Social Science: Human-Environment Interactions and Sustainability” (2010) • Social simulation Schelling, “Micromotives and macrobehavior” (1978). Batty, “Cities and complexity” (2005). • Game theory von Neumann and Morgenstern, “Theory of games and economic behavior” (1944) Nash, "Equilibrium points in n-person games“ (1950). • Evolutionary dynamics Maynard Smith,  ”Evolution and the theory of games” (1982) Axelrod, “Evolution of cooperation” (1988). Novak, “Evolutionary dynamics: exploring the equations of life” (2005). • Institutional analysis Ostrom, “Governing the commons” (1990).

15. Common pool resources (Elinor Ostrom)

16. The ultimate common pool resource

17. Governing the commons [Ostrom, Science, 2005]

18. Governing the commons: Ostrom´s conditions Clearly defined boundaries. Congruence between appropriation and provision rules and local conditions. Collective-choice arrangements. Monitoring and graduated sanctions. Conflict-resolution mechanisms. Minimal recognition of rights to organize. Organized governance activities.

19. Ostrom on governing the commons “The challenge is how best to limit the use of natural resources so as to ensure their long-term economic viability.” “Neither the state nor the market is uniformly successful in enabling individuals to sustain long-term, productive use of natural resource systems.” “Optimal equilibrium with centralized control is based on assumptions concerning accuracy of information, monitoring capabilities, sanctioning reliability, and zero costs of administration.”

20. Conclusion Spatial models of human-environment interactions can support the study of common pool resources
