Definition of optimality:
• Acceptability, satisficing
• Requires a participatory approach:– Identification and involvement of
major actors, stakeholders
– Shared information basis
– Easy access, intuitive understanding
– Web based, local workshops

In summary:In summary:In summary:In summary:Problems are largely man made
Solutions involve valuation, trade off: subjective – political – choices;
NOT optimal, but acceptable to a majority
Democratic decision making processes
No single method, solutions need a well balanced combination of strategies and tools, based on preferences, believes, fears, and a little science.
