2.1 Resilience of a system:
Question | Answer |
---|---|
1. Equilibrium resilience | concentrates on stability near and equilibrium steady-state where resistance to disturbance and speed of return to the equilibrium are used to measure resilience. |
2. Ecosystem resilience | emphasizes conditions far from any equilibrium in which instabilities can flip a system into another regime of behavior , to another stability domain. Measure of resilience is the magnitude of disturbance that can be absorbed or accommodated before the sy |
Examples of natural resource management led to a less resilient system in the sense of ecosystem resilience: | 1. The loss of genetic variation in small populations may lead to extinction. |
Examples of natural resource management led to a less resilient system in the sense of ecosystem resilience: | 2. Stability of flows by dams, exotic fishes may kill native fishes. |
Examples of natural resource management led to a less resilient system in the sense of ecosystem resilience: | 3. Suppression of fire-prone ecosystems may cause huge fires due to fuel buildup. |
Examples of natural resource management led to a less resilient system in the sense of ecosystem resilience: | 4. Monoculture, energy intensive farming practices reduce variation and loss of resilience. Require large input of energy and often societal subsidies. |
Examples of natural resource management led to a less resilient system in the sense of ecosystem resilience: | 5. Natural, lateral flow variation (periodic food plan inundation). Attempted command-and-control of river flows, allowing expansive food-plan development, resulted in un-resilient river-social system and economic destruction. |
