Q

Define ‘disaster’

A

16
Q

What is physical vulnerability?

A

When people live in hazard prone areas in buildings with little protection

17
Q

What is economic vulnerability?

A

When people risk losing their jobs, assets and money

18
Q

What is social vulnerability?

A

When a household or community is unable to support the disadvantaged groups within it e.g. political isolation

19
Q

What is knowledge vulnerability?

A

When people lack education and training and/or there are a lack of warning systems

20
Q

What is environmental vulnerability?

A

When the area people live in has increased in hazard risk because of population pressure forcing people into riskier areas

25
Q

What is the PAR model?

A

What should be enforced to reduce the risk of a disaster

26
Q

Name the four components of the PAR model

A

Root causes, dynamic pressures, unsafe conditions and natural hazards

27
Q

Describe root causes of the PAR model

A

Limited access to power, structures and resources

Ideologies: political and economic systems

28
Q

Describe dynamic pressures of the PAR model

A

Lack of skills, training, local investment, press freedom and ethical standards
Macro forces: population change, urbanisation, deforestation, arms expenditure and debt repayment

29
Q

Describe unsafe conditions of the PAR model

A
  • Fragile physical environment
  • Fragile local economy
  • Vulnerability
  • Public actions
30
Q

What equation comes between {root causes, dynamic pressures, unsafe conditions} and {natural hazards}?

A

Risk = hazard + vulnerability

31
Q

What are hazard profiles?

A

A technique used to understand the physical characteristics of types of hazards used to contrast and rank the risks

32
