Transcript of "Module 9 introduction to disaster risk management"
Session 1.b Introduction to Disaster Risk Management Training of Trainers Workshop on “ ICT for Disaster Risk Management” 22 to 26 February 2011 Incheon, Republic of Korea
Basic Definitions, Terms & ICT Learning Objectives <ul><li>At the end of this session, you should be able to define: </li></ul><ul><ul><li>Define disaster, hazard, risk, elements at risk, vulnerability, capacity, response, relief, rehabilitation, reconstruction, mitigation, preparedness and prevention </li></ul></ul><ul><ul><li>Understand ICT needs in disaster Risk Management </li></ul></ul>
Phenomenon or situation, which has the potential to cause disruption or damage to people, their property, their services and their environment Hazards are the result of an interaction between human activities and the natural and technological processes that can generate extreme events. There is a potential for occurrence of an event Hazard
Disaster Serious disruption of functioning of society, causing widespread human, material or environmental losses, which exceed the ability of the affected people to cope using their own resources. An event, either man-made or natural, sudden or progressive, causing widespread human, material or environmental losses
Vulnerability - Vulnerability a condition or sets of conditions that reduces people’s ability to prepare for, withstand or respond to a hazard
Risk Risk – A probability that a community’s structure or geographic area is to be damaged or disrupted by the impact of a particular hazard, on account of their nature, construction and proximity to a hazardous area.
Capacity Capacities are those positive condition or abilities which increase a community’s ability to deal with hazards.
Hazard Vulnerability x Disaster Risk Capacity =
Persons, buildings, crops or other such like societal components exposed to known hazard, which are likely to be adversely affected by the impact of the hazard. Elements at Risk
Response Measures that are required in search and rescue of survivors, as well to meet the basic needs for shelter, water, food and health care.
Relief Actions taken immediately following the impact of a disaster when exceptional measures are required to meet the basic needs of the survivors.
What is the difference between 1. Recovery 2. Rehabilitation 3. Reconstruction
Recovery The process undertaken by a disaster-affected community to fully restore itself to pre-disaster level of functioning.
Rehabilitation <ul><li>Actions taken in the aftermath of a disaster to: </li></ul><ul><li>assist victims to repair their dwellings; </li></ul><ul><li>re-establish essential services; </li></ul><ul><li>revive key economic and social activities </li></ul>
Reconstruction Permanent measures to repair or replace damaged dwellings and infrastructure and to set the economy back on course.
Mitigation Mitigation - measures taken prior to the impact of a disaster to minimize its effects (sometimes referred to as structural and non-structural measures).
Structural Mitigation Land Use Management Mitigation
Preparedness Measures taken in anticipation of a disaster to ensure that appropriate and effective actions are taken in the aftermath.
Disaster Risk Management <ul><li>A broad range of activities designed to: </li></ul><ul><li>Prevent the loss of lives </li></ul><ul><li>Minimize human suffering </li></ul><ul><li>Inform the public and authorities of risk </li></ul><ul><li>Minimize property damage and economic loss </li></ul><ul><li>Speed up the recovery process </li></ul>
Example : Identify Information needs for appropriate and adequate Risk Reduction Measures : Risk Assessment (HVCA) <ul><li>To ensure the appropriateness and relevance of the risk reduction measures </li></ul>2. Prioritize elements at risk 3. Identify possible risk reduction measures 4. Check which ‘V’ are addressed and which ‘C’ are used 5. Compare measures with resources, skills, organizational mandate, etc. 6. Rank measures and reach consensus 1. Review HVCA
