Albert NorströmStockholm Resilience CentreIntroduction to resilience thinking 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 Albert NorströmStockholm Resilience CentreIntroduction to resilience thinking
