Q

how long does the rehabilitation stage last?

A

days to weeks

17
Q

what is the stage after rehabilitation?

A

reconstruction

18
Q

how long does reconstruction last?

A

weeks to years

19
Q

what is included in reconstruction

A

property and crops rebuilt

learn how to respond better

20
Q

what is flexible about the model?

A

there are variations that allow it to show differences between different hazards

21
Q

what is the model also known as?

A

disaster response model

22
Q

what doesn’t the parks model take into account?

A

the different types of spatial variations

states that all areas will respond the same

23
Q

what is stage one?

A

where it is prior to the event and quality of life is at its normal level

24
Q

what is stage 2?

A

where hazard hits quality of life stays normal

25
Q

what is stage 3?

A

where the event has happened and search and rescue in under way, quality of life stays low for a while

26
Q

stage 4?

A

when relief strategies are underway and organised system

can take weeks to months but quality of life does improve

27
Q

what is stage 5?

A

this si when long term responses are under way, reconstructing etc
can return quality of life back to normal or higher
