Disaster Management Essay


Disaster is a sudden, calamitous event bringing great damage, loss, destruction and devastation to life and property. WHO defines Disaster as "any occurrence, that causes damage, ecological disruption, loss of human life, deterioration of health and health services, on a scale sufficient to warrant an extraordinary response from outside the affected community or area"

The damage caused by disasters is immeasurable and varies with the geographical location, climate and the type of the earth surface/degree of vulnerability. This influences the mental, socio-economic, political and cultural state of the affected area

Definition of Disaster Management

"Disaster management" can be defined as the range of activities designed to maintain control

over disaster and emergency situations and to provide a framework for helping at-risk persons

to avoid or recover from the impact of the disaster. Disaster management deals with situations

that occur prior to, during, and after the disaster.

The Objectives of Disaster Management

The objectives of disaster management are:

to reduce or avoid the human, physical, and economic losses suffered by individuals, by the society, and by the country at large

to reduce personal suffering

to speed recovery.


Generally, disasters are of two types - Natural and Manmade. Based on the devastation, these are further classified into major/minor natural disaster and major/minor manmade disasters. some of the disasters are listed below:

Disaster Management Cycle

Disaster management is a cyclical process; the end of one phase is the beginning of another (see diagram below), although one phase of the cycle does not necessarily have to be completed in order for the next to take place. Often several phases are taking place concurrently. Timely decision making during each phase results in greater preparedness, better warnings, reduced vulnerability and/or the prevention of future disasters. The complete disaster management cycle includes the shaping of public

policies and plans...

Disaster Management


All disaster managers must make decisions. Their decision involves a comparison between several alternatives and an evaluation of the outcome. The quality of the decisions managers make is the true measure of their performance. Each operational decision influences future actions, which in turn, require further decisions. Errors in decision-making, therefore, tend to be cumulative.

Decision-making is the major responsibility of a disaster manager, regardless of his or her functional area or level in the organization.
Some of these decisions may have a strong impact on the organization, while others will be important, but less crucial. The important point, however, is that all decisions will…show more content…

Of course, this type of decision-making environment is rare. Suppose the manager of a relief agency has been alerted by an early warning system that 2,000 refugees will arrive in his refugee camp in one week. He would be foolish not to order supplies for 2,000 people and prepare to distribute them. In this example, the decision-maker is fortunate because accurate information about future events is available. But, in most situations, the manager does not know exactly what will occur.
Under these latter conditions, the manager is forced to use probabilities to make decisions.

2) Decision-making Under Conditions of Risk æ In some situations, a manager is able to estimate the probability that certain variables could occur. The ability to estimate may be due to experience, incomplete, but reliable information, or, in some cases, an accurate report. When estimates are made, a degree of risk is involved, but some amount of information about the situation is available. The situation requires estimating the probability that one or more known variables might influence the decision being made. If the basis for the decision is stated in terms of maximizing results, for example, service levels the decision-maker would select the alternative, that produces the best result. However, if the basis for the decision is stated in terms of minimizing the outcome, for example, costs, the decision-maker would select the
