Apakah kehati dapat punah?

meskipun kehati merupakan sumberdaya alam

yang renewable, tetapi memiliki batas minimal

populasi untuk mempertahankan dirinya dari

ancaman kepunahan (jika kondisinya di bawah

nilai minimum viable population)

Risk

The expectation value of losses (death, injury,

extinct, etc), that would be caused by a hazard

Probability of a loss, and this depend on three

elements, hazard, vulnerability, and exposure.

If any of these three elements in risks

increases or decreases, then the risk increases

or decreases respectively (Crichton, 1999)

Ancaman (hazard)

Kejadian yang berpotensi menyebabkan

hilangnya kehati


10/24

Hazard

The probability of occurence of

a potentially damaging

phenomenon within a giventime period and area (EEA, 2005)

The probability of occurence assosiated with

an extreme event that can cause a failure(UNDRO, 1991; Plate, 2002)

Resilience

A measure of the recovery time of a system(Correira et all, 1987)

The capacity to recover from emergencies,

and as a counterbalance to vulnerability(Buckle, 1998)

The ability to absorb the impact of bussiness

interruption, and continue to provide aminimum acceptable level of service (DisasterRecovery Journal, 2005)


14/24

Vulnerability

The characteristics of an

individual or group in term

of their capacity toanticipate, cope with,

resist and recover from

the impact of naturalor man-made hazard


15/24

Capacity

The ability to cope with threats includes the

ability to absorb by guarding against oradapting to them. Its also includes provisionsmade in advance to pay for potential

damages, for instance by mobilyzing insurancerepayments, savings or contingency reserves

(UNEP, 2002)
