Definition Of Ecosystem Resilience

Build the capacity of the environment economies and societies to anticipate respond to and recover from disturbances and shocks through.

Definition of ecosystem resilience. In ecology resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. Resilience is the ability and rate of an ecosystem to recover from a disturbance and return to its pre disturbed state. Ref resilient ecosystems are characterized as adaptable flexible and able to deal with change and uncertainty. Some ecosystems can shift greatly from their previous state.

Such perturbations and disturbances can include stochastic events such as fires flooding windstorms insect population explosions and human activities such as deforestation fracking of the ground for oil extraction pesticide sprayed in soil and. Ecosystems are complex and dynamic. Ecological resilience also called ecological robustness the ability of an ecosystem to maintain its normal patterns of nutrient cycling and biomass production after being subjected to damage caused by an ecological disturbance the term resilience is a term that is sometimes used interchangeably with robustness to describe the ability of a system to continue functioning amid and recover from. Quantifying resilience is difficult.

Some ecosystems are better at resisting change than others and therefore have high resistance. Resilience ecosystem means the capacity of an ecosystem that is adversely affected by a disturbance to recover to its prior condition. Resilience thinking is fully consistent with the twelve principles of the ecosystem approach 3 for equitable inclusive and holistic management agreed by the international convention on biological diversity 4. Thing as ecosystem resilience which they define as the ability to recover if the disturbance causes change.

Strengthening ecosystem restoration in particular of wetlands dryland vegetation coastal zones and watersheds including. Enhance ecosystem resilience. The capacity of ecosystems to deal with disturbances either by resisting them recovering from them or adapting to them whilst retaining their ability to deliver services and benefits now and in the future2. Ecological resilience refers to the ability of an ecosystem to maintain key functions and processes in the face of stresses or pressures by resisting and then adapting to change.

With specific reference to conway s 1985 definition of sustainability lynam and herdt 1992. Protection and conservation of genetic diversity and terrestrial coastal and marine biodiversity. A resilient organism or ecosystem can withstand a disturbance without shifting to an alternative state and can continue to function as if the disturbance had not occurred 52 resilience can be described by the magnitude of disturbance that is needed before a state shift occurs 50 53 for example if a hypothetical tundra.
