What are the major theories of emergency management?
Emergency management theory must also incorporate principles such as disaster prevention, preparedness and improvisation. It is also recommended that the needs of special populations be taken into consideration, and an exploration of political and economic marginalization be given.

Why is the par model useful?
The PAR model can be used to help understand this. The PAR model suggests that the socio-economic context of a hazard is important. In poor, badly governed (root causes) places with rapid change and low capacity (dynamic pressures) and low coping capacity (unsafe conditions), disasters are likely.
What are the 4 stages of the hazard management cycle?
These common elements allow you to prepare for and protect yourself and your animals from disaster.
