  • 2. "O my Lord! Open for me my chest (grant me self-confidence, contentment, and boldness).
    "And ease my task for me;
    "And make loose the knot (the defect) from my tongue, (i.e. remove the incorrectness from my speech)
    That they may understand my speech.
  • 3. Join these 9 point with Four Lines without picking your pen.
    You have 2 minutes for that
    Take home Message: Think Out of the Box
  • 4. What is Disaster Risk Assessment ??
    You already know what is a RISK….
    Assessment is a participatory process undertaken in phases and involving on spot collection, interpreting and analyzing of information from sources.
    Disaster risk assessment at community level is Hazards, Vulnerability and Capacity Assessment
  • 5. What is Disaster Risk Assessment ??
    DRA involves a participatory analysis and combination of both scientific and empirical data concerning the probabilities of hazards in particular area, the negative effects expected to result to each element at risk for each particular hazard and considering the coping mechanism
    Risk assessment is a structured analytical procedure to identify hazard and to estimate the probability of their occurrence and the consequences in the lights of the conditions. These estimates are then compared with a standard or criterion in order to decide whether or not action is desirable, to reduce the probabilities or to protect people property or environment
  • 6. Disaster Risk Assessment Process
    Hazard Assessment
    Vulnerability Assessment
    Capacity Assessment
    Risk Perception
  • 7. Hazard Assessment
    • Identify, list down, and describe the nature of hazards in terms of its recurrence, reasonability, location, possibility of early warning and general knowledge of the people about the hazard
    Vulnerability Assessment
    Identify what elements are at risk and why (refer to unsafe conditions, dynamic pressures and root causes)
  • 8. Capacity Assessment
    • What are the peoples coping strategies, what resources are still available, who has access and control over these resource??
    Community’s Risk Measurement
    Understanding the people’s perception of risk

  • 11. HAZARD ASSESSMENT
    Courtesy:FalakNawaz (ADPC)
  • 12. The purpose is to specify the nature and behavior of the potential hazards and threats people face
    Hazard assessment means the identification of hazards in given location (D&E Reference Conference 1998)
    Hazard Assessment is a process of estimating, for defined areas, the probabilities of the occurrence of potentially damaging phenomenon of given magnitude within a specified period of time (Simeon Institute 1998)
  • 13. The process of studying the nature of hazards determining its essential features (degree of severity, duration, extent of the impact area) and their relationship
  • 14. Types of Hazards
  • 15.
  • 16.
  • 17. Factors to consider in understanding the nature & behavior of hazards
    Origin
    Factors which create, result in a hazard. Can be natural or man made
    Warning Signs and signals
    Scientific & indigenous indicators that hazard is likely to occur
    Rainfall duration, intensity, quantity, speed of wind, temperature, movement of animals, insects and birds
    Forewarning
    Time gap between warning signs & the impact of hazard
    Relatively short but can vary from a few hours (over-night) to a few days
  • 18. Factors to consider in understanding the nature & behavior of hazards
    • Force
    Factors that make the power of hazards, e.g. intensity and magnitude of flooding
    • Speed of Onset
    Rapidity of arrival and impact
    • Frequency
    Time related patterns of occurrence of hazards
    • Seasonality
    Occurrence of a hazard in a particular time of the year
    • Duration
    Hazard’s presence in a time scale
  • 19. Tools for Hazard Assessment
    Hazard Maps:
    To locate the probable area covered by a hazard’s impact and the elements at risk
    Historical Profile or timeline:
    Can make us understand how hazards have changed over time; which hazards have happened in the past or the start of particular hazard occurrence
    Seasonal calendar:
    Visualizes the ti,e. frequency and duration of common hazards
    Hazard matrix
    Helps to systemize information on the characterizes of hazards, specifically warning signs and signals, forewarning, speed of onset, frequency, period of occurrence and duration
