This document provides an overview of disaster risk assessment. It defines disaster risk assessment as a participatory analysis of hazards, vulnerability, and capacity. The disaster risk assessment process involves hazard assessment to identify hazards, vulnerability assessment to identify elements at risk, and capacity assessment. Tools for hazard assessment discussed include hazard maps, historical profiles, seasonal calendars, and hazard matrices. Key factors to consider in understanding hazards are also outlined, such as origin, warning signs, force, speed of onset, frequency, seasonality, and duration.

- 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 mechanismRisk 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

- 7. Hazard AssessmentIdentify, 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 hazardVulnerability AssessmentIdentify what elements are at risk and why (refer to unsafe conditions, dynamic pressures and root causes)
- 8. Capacity AssessmentWhat are the peoples coping strategies, what resources are still available, who has access and control over these resource??Community’s Risk MeasurementUnderstanding the people’s perception of risk

- 10. Objectives and Outputs of Disaster Risk Assessment
- 12. The purpose is to specify the nature and behavior of the potential hazards and threats people faceHazard 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
- 17. Factors to consider in understanding the nature & behavior of hazardsOriginFactors which create, result in a hazard. Can be natural or man madeWarning Signs and signals Scientific & indigenous indicators that hazard is likely to occurRainfall duration, intensity, quantity, speed of wind, temperature, movement of animals, insects and birdsForewarningTime gap between warning signs & the impact of hazardRelatively short but can vary from a few hours (over-night) to a few days
- 18. Factors to consider in understanding the nature & behavior of hazardsForceFactors that make the power of hazards, e.g. intensity and magnitude of floodingSpeed of OnsetRapidity of arrival and impactFrequency Time related patterns of occurrence of hazardsSeasonalityOccurrence of a hazard in a particular time of the year Duration Hazard’s presence in a time scale
- 19. Tools for Hazard AssessmentHazard Maps: To locate the probable area covered by a hazard’s impact and the elements at riskHistorical 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 occurrenceSeasonal calendar: Visualizes the ti,e. frequency and duration of common hazardsHazard 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
