We are in the anthropocene
Rapid change in major processes and resources
Human use of goods and services is increasing
Most ecosystem services are decreasing
We seem to be approaching thresholds
Governance systems that makes it possible for society to relate with environmental assets in
a fashion that secures their capacity to support societal development for a long time
in the future.
Ability to maintain functioning despite stress, shocks or disturbance
Reflects ability of system to self-organize; build capacity for learning and adaptation

Engineering vs ecosystem resilience
Natural systems were treated as predictable systems with single equilibria
Ecosystems as linear systems
