- 33. Disasters as theConsequence of Natural Hazards The Philippine Disaster Risk Reduction and Management Act of 2010 adopted the definition of UNISDR of hazard, naturalortechnological(man-made)as,
- 34.
- 35. Hazard, Vulnerability, andDisaster Risk Risk (R) = Hazard (H) x Vulnerability (V) Where: Hazard: a dangerous phenomenon, substance, human activity or condition that may cause loss of life, injury or other health impacts, property damage, loss of livelihood and services, social and economic disruption, or environmental damage. (RA 10121) Vulnerability: is the extent to which community’s structure, services or environment are likely to damage or disrupted by the impact of a hazard.
- 36. Risk, Disaster Riskand Disaster Risk Assessment (DRA) • RA 10121: Risk is the combination of probability of an event (hazard) and its negative consequences (vulnerability). • Epidemiology: Risk is the probability that a particular outcome will occur following a particular exposure. • Finance: Risk is the probability that an actual return on an investment will be lower than the expected return.
- 37. What is Risk? …”isthe probability of uncertain future events; the probable frequency and magnitude of future loss the possibility of suffering harm, loss, or danger; and the probability of an accident occurring within a certain time, together with the consequences for people, property, and the environment.
- 38. What is Loss? Lossesor impacts refer to the number of human losses, the type and amount of infrastructure damaged or destroyed , or the amount of crops damaged other economic losses, or quantifiable damage to the natural environment (Peduzzi, 2012)
- 39. What is RiskAnalysis? It is the systematic identification, evaluation, and assessment of risk objects and hazards.
- 40. What is DisasterRisk? The potential disaster losses in lives, health status, livelihood, assets, and services, which could occur to a particular community or a society over some specified future time period. (RA 10121)
- 41. What is DisasterRisk Assessment (DRA)? It is a methodology to determine the nature and extent of risk by analyzing potential hazards and evaluating existing conditions of vulnerability that together could potentially harm exposed people, property, services, livelihood, and environment on which they depend. (RA 10121)
- 42. Disaster Risk Reduction(DRR) The concept and practice of reducing disaster risks through systematic efforts to analyze and manage the casual factors of disasters, including through reduced exposures to hazards, lessened vulnerability of people and property, wise management of land and the environment, and the improved preparedness for adverse events. (RA 10121)
- 43. R = H* E * V/C Where; • Exposure (E) is the number of “people, property, systems or other elements present in hazard zones that are thereby subject to potential losses.” (UNISDR, 2011b) • Coping Capacity (C) is “the ability of people, organizations and systems, using available skills and resources, to face and manage adverse conditions, emergencies, or disasters” (UNISDR, 2011a) • Hazard (H) and Vulnerability (V) as defined earlier
- 44. Disaster Risk Reduction(DRR) The concept and practice of reducing disaster risks through systematic efforts to analyze and manage the casual factors of disasters, including through reduced exposures to hazards, lessened vulnerability of people and property, wise management of land and the environment, and the improved preparedness for adverse events. (RA 10121)
- 45. Conceptual Model ofDisaster Risk Assessment Risk-based – UNDP Disaster Risk Index (DRI) R ∞ H x V R= Risk of damage H = Hazard (e.g. typhoon and its strong winds V = Vulnerability (Degree of vulnerability of structures to strong winds (e.g. residential buildings, school, houses, etc. Disaster Risk Reduction (DRR)
