Disaster Risk Management
Strategic shift from managing a disastrous event to more preventive and proactive approaches!!
The conceptual framework of elements considered with the possibilities to minimize vulnerabilities and disaster risks throughout a society, to avoid (prevention) or to limit (mitigation and preparedness) the adverse impacts of hazards, within the broad context of sustainable development !
What is the Hazard?
The conditions determined by physical, social, economic, and environmentalfactors or processes, which increase the susceptibility of a community to the impact of hazards.
Non-resistant house & school building
The probability of harmful consequences, or expected losses (deaths, injuries, property, livelihoods, economic activity disrupted or environment damaged) resulting from interactions between natural or human-induced hazards & vulnerable conditions.
Risk = Hazards x Vulnerability
A serious disruption of the functioning of a community or a society causing widespread human, material, economic or environmental losses which exceed the ability of the affected community or society to cope using its own resources.
A disaster is a function of the risk process.
It results from the combination of hazards, conditions of vulnerability and insufficient capacity or measures to reduce the potential negative consequences of risk.
