3. Events Systems Paradigms Wetlands Example Patterns Wetlands are wasted land, an unused resource

4. Events Systems Paradigms Wetlands Example Patterns Wetlands are wasted land, an unused resource Process to encourage development, markets created, regulations assisted, etc.

5. Events Systems Paradigms Wetlands Example Patterns Wetlands are wasted land, an unused resource Process to encourage development, markets created, regulations assisted, etc. Wetlands filled in, levees built, riparian zones changed, etc.

6. Events Systems Paradigms Wetlands Example Patterns Wetlands are wasted land, an unused resource Process to encourage development, markets created, regulations assisted, etc. Wetlands filled in, levees built, riparian zones changed, etc. Floods, decrease in base flows, lower water quality, etc.

7. Time and Type of Change Events Systems Paradigms Patterns Reactive Adaptive Creative Generative

8. Time and Type of Change Events Systems Paradigms Patterns Reactive Adaptive Creative Generative Leverage for Change

9. Change happens in steps No change forever Spontaneous Evolution

10. Paradigm Shift Events Systems Paradigms Patterns Paradigms Patterns Events Systems

11. System Thinking As A Perspective Think long term See the big picture Focus on structure, not on blame Look for interdependence and cause and effect relationships Change perspectives to see new leveraging points Consider how metal models determine our future Hold the tension of paradox and controversy without feeling the need to resolve them quickly

12. Mechanistic Thinking Parts Objects Events Isolation Specificity Statics Simplicity Systems Thinking Wholes Relationships Structures Interdependence Generality Dynamics Complexity

13. Events Systems Paradigms Pre CWA Example Patterns Rivers on Fire, toxic waste sites (extremes), etc.

14. Events Systems Paradigms Pre CWA Example Patterns Illnesses, dead zones, unusable water, etc. Rivers on Fire, toxic waste sites (extremes), etc.

15. Events Systems Paradigms Pre CWA Example Patterns Infrastructures that did not treat water, used waterways as disposal, little regulation, etc. Illnesses, dead zones, unusable water, etc. Rivers on Fire, toxic waste sites (extremes), etc.

16. Events Systems Paradigms Pre CWA Example Patterns Waterbodies can absorb pollution from our activities Infrastructures that did not treat water, used waterways as disposal, little regulation, etc. Illnesses, dead zones, unusable water, etc. Rivers on Fire, toxic waste sites (extremes), etc.

17. Events Systems Paradigms CWA RESPONSE Patterns We CAN treat pollutants, and will. CWA, local regulations, Capital infrastructure investment, cost sharing, etc. Uses protected, pollutants added, etc. Beach closure ecoli- go back to system, etc.

18. Events Systems Paradigms CWA RESPONSE Patterns We CAN treat pollutants, and will. CWA, local regulations, Capital infrastructure investment, cost sharing, etc. Uses protected, pollutants added, etc. Beach closure ecoli- go back to system, etc.

19. SCALE And the NPS Problem

21. Events Systems Paradigms NEW PARADIGM for these pollutants Patterns Prevention is the way, we CAN’T treat everything cost effective Continue to define limits, monitoring discharges but create systems that prevent untreatable (cost/technology) pollutants, who knows? Who knows? Clean water for the future.....
