Before discussing disaster management, let us first know

Phases of disaster management

Pre-crisis: Preparedness

  • These include long-term prevention measures like
    • construction of embankments to prevent flooding,
    • creating or augmenting irrigation facilities and adopting water shed management as drought proofing measures,
    • increasing plantations for reducing the occurrence of landslides,
  • Crisis can also be mitigated through various short-term measures, for example,
    • better enforcement of building codes and zoning regulations,
    • proper maintenance of drainage systems,
    • better awareness and public education to reduce the risks of hazards etc.

During Crisis: Emergency Response

  • When a crisis actually occurs, those affected by it require a speedy response to alleviate and minimize suffering and losses.
  • The primary activities could include: evacuation, search and rescue, followed by provision of basic needs such as food, clothing, shelter, medicines and other necessities essential to bring the life of the affected community back to a degree of normalcy.

 

Post-Crisis

  • Recovery: This is the stage when efforts are made to achieve early recovery and reduce vulnerability and future risks. It comprises activities that encompass two overlapping phases of rehabilitation and reconstruction.
  • Rehabilitation: Includes provision of temporary public utilities and housing as interim measures to assist long term recovery.
  • Reconstruction: Includes construction of damaged infrastructure and habitats and enabling sustainable livelihoods.
