DRR basic concepts and terminologies of disaster risk reduction DRR

  1. 1. Basic Concepts andBasic Concepts and TerminologiesTerminologies in Disaster Managementin Disaster Management Adopted from 8th EVRC Course Held in Feb 2009 in Bangkok
  2. 2. Basic Definitions & Terms LearningLearning ObjectivesObjectives At the end of this session, you should be able to: Define disaster,hazard, risk, elements at risk, vulnerability, capacity, response, relief, rehabilitation, reconstruction, development, mitigation, preparedness and prevention
  3. 3. HAZARDHAZARD Phenomenon or situation, which has the potential to cause disruption or damage to people, their property, their services and their environment There is a potential for occurrence of an event
  4. 4. DISASTERDISASTER The serious disruption of the 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
  5. 5. VulnerabilityVulnerability Is a condition or sets of conditions that reduces people’s ability to prepare for, withstand or respond to a hazard
  6. 6. CapacityCapacity Those positive condition or abilities which increase a community’s ability to deal with hazards.
  7. 7. The 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. RiskRisk
  8. 8. Hazard Vulnerabilityx Disaster Risk Capacity =
  9. 9. Hazard Vulnerabilityx Disaster Risk Capacity =
  10. 10. Elements at RiskElements at Risk Exposed Elements 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.
  11. 11. THE DISASTER MANAGEMENT CYCLE DISASTER RESPONSE/RELIEF REHABILITATION RECONSTRUCTION DEVELOPMENT PREVENTION MITIGATION PREPAREDNESS
  12. 12. ResponseResponse Actions taken immediately following the impact of a disaster when exceptional measures are required to meet the basic needs of the survivors.
  13. 13. ReliefRelief Measures that are required in search and rescue of survivors, as well to meet the basic needs for shelter, water, food and health care.
  14. 14. What is difference between 1. Recovery 2. Rehabilitation 3. Reconstruction
  15. 15. Preparedness Mitigation Reconstruction Rehabilitation Relief Disaster impact Recovery phase 19
  16. 16. RecoveryRecovery The process undertaken by a disaster affected community to fully restore itself to pre-disaster level of functioning.
  17. 17. 21
  18. 18. 22
  19. 19. RehabilitationRehabilitation Actions taken in the aftermath of a disaster to: • assist victims to repair their dwellings; • re-establish essential services; • revive key economic and social activities
  20. 20. ReconstructionReconstruction Permanent measures to repair or replace damaged dwellings and infrastructure and to set the economy back on course.
  21. 21. DevelopmentDevelopment Sustained efforts intended to improve or maintain the social and economic well-being of a community
  22. 22. PreventionPrevention Measures taken to avert a disaster from occurring, if possible (to impede a hazard so that it does not have any harmful effects).
  23. 23. MitigationMitigation Measures taken prior to the impact of a disaster to minimize its effects (sometimes referred to as structural and non-structural measures).
  24. 24. PreparednessPreparedness Measures taken in anticipation of a disaster to ensure that appropriate and effective actions are taken in the aftermath.

  30. 30. …..for Life to continue……. _____________________________________________________ SRI - system of rice intensification- reducing water demand and making crops more resistant to extreme weather events
  31. 31. Seed stores - Access to disaster- resistant seed and plants
  32. 32. Cyclone shelters in coastal areas or flood shelters along major rivers
  33. 33. Mock drill on emergency/first aid
  34. 34. Early warning: international, national and on a community level
  35. 35. Seed and food stocks/storage systems
  36. 36. DRR Committees and communal actions
  37. 37. DRR Climate Change Adaptation Climate Change Adaptation and DRR… CC-adaptation… •Does risk assessment in the first place •Looks at slow- and sudden-onset disasters •Has a long-term vision •Takes the perpetrators of CC into account •Addresses GHG reduction (mitigation)
  38. 38. What is the differenceWhat is the difference between DM and DRMbetween DM and DRM
  39. 39. Disaster Management A collective term encompassing all aspects of planning for preparing and responding to disasters. It refers to the management of the consequences of disasters.
  40. 40. Disaster Risk Management A broad range of activities designed to:  Prevent the loss of lives  Minimize human suffering  Inform the public and authorities of risk  Minimize property damage and economic loss  Speed up the recovery process
  41. 41. Disaster risk management - Stress on proactive disaster management responses of prevention, mitigation and preparedness  Prevent, reduce, transfer or live with disaster risk  Public safety, disaster resilience, sustainable development for all
  42. 42. THE DISASTER MANAGEMENT CYCLE DISASTER RESPONSE REHABILITATION RECONSTRUCTION DEVELOPMENT PREVENTION MITIGATION PREPAREDNESS
  43. 43. Disaste r Preparedness Prevention/Mitigatio n Reconstruction Emergency Response Early Warning Rehabilitation DisasterRiskManagement Risk Assessment Awareness and Capacity Building
  44. 44. ConclusionConclusion • Clear cut distinction between different terminologies • Difference between Preparedness, Mitigation, and Prevention, • Difference between Recovery, Rehabilitation and Reconstruction • Difference between DM and DRM • Sharpen our knowledge about different terminologies
