Disaster Management Definition & Objectives
In Disaster manangment we prepare for mitigation and managing all the activities which can help to reduce the impact, save lives and communities’ rehabilitation.
We form common objectives and values where we encourage stakeholders to plan for and deal with potential and actual disasters. It is the integration of all activities involved in well-organized manner whether it is before, during and after occurrence, here we use both financial and human resources effectively. The principles of disaster management Cycle means undertaking all activities at different time like
- Reducing risk to potential hazards before disaster occur with the help of development both short and long term strategies
- Make sure the appropriate response and assistance to the affect areas during and immediately after disaster
- Achieve quick and sustained recovery and rehabilitation after the disaster took place.
Communication facilities for disaster management include Digital Cyclone Warning Dissemination System (DCWDS) it is used pre hazard information. The WLL – VSAT in used for audio communication facility. The MSS Type C reporting uses for sending message through satellite. For online and video facility AES-SNG system in very helpful.
In order to understand the principles of disaster mitigation it is important to clearly understand the phases of disaster management cycle like mitigation, preparedness, response, relief & recovery and disaster management.
Mitigation is the use of strategies to reduce risks prior to, during and post disaster. It is related to short term and long term measures for example, preventing or reducing risk properly or lives by improving the inherent capacities of people and strengths of habitants, infrastructure and critical facilities. We can define mitigation policies or activities that will reduce an area’s vulnerability to damage from future. Normally, mitigation refers to actions taken before a hazard becomes a disaster.
For example reduce the risk of landslides you could erect a strong fence around the hazardous loose rock on the hill to prevent debris from falling on the settlement in the foothill, alternatively, you could reduce the impact of the landslide by either moving the communities from the foothills, strengthen the houses to withstand impact of the falling stone, or growing a dense forest between the settlements and the hills. Prior to occurrences. Valuables could also be insured if they are vulnerable. All actions involved in reducing risks or impacts are part of mitigation.
Below are the four basic actions of mitigation
- Preventing hazards from occurring
- Reducing risks
- Reducing impacts or consequences
- Distributing risks
Preparedness means minimizing the adverse effects of a hazards through precautionary actions and measures. It entails a series of actions to ensure speedy, effective, and efficient organization and delivery of relief and related responses following the onset of sudden catastrophe.
