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

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??

Communitys Risk Measurement
Understanding the peoples perception of risk

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

Hazards presence in a time scale
19. Tools for Hazard Assessment
Hazard Maps:
To locate the probable area covered by a hazards 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
