Interdisciplinary cooperation and systems modelling as means to
govern the anthropocene

Solving large scale problems
• Problem formulation
• Importance to find a solution
• The way to carry through the solution
• CFC exchange to reduce ozone depletion
• Convention on Long-range Transboundary Air Pollution (1979) (Acidification of low buffer soils and lakes in mainly Scandinavia)
• IPCC climate models convincing (most) people
To be remembered
• Most environmental degrading is legal
• Sciences get more and more fragmented (post-normal science; Ravetz) (post-modernity; Beck)
• Dualism between human and nature (Carolyn Merchant and others)

sustainability
The county of Jämtland (Sweden) to be modelled concerning flows of material (carbon) and energy (exergy) thus finding the answer to the question: Is it possible to reach sustainability?

Are there alternatives to such investments that give higher environmental long-term yield?

Governing the Anthropocenemeans governing complexity…
• Clarify the problem as a model
• Clarify the decision tree, showing the parameters of the decision process
• Environmental laws, recommendations and subsidies have to be used to push long-term sustainability decisions Lunch
