2.1 Resilience of a system:

QuestionAnswer
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.
