<strong>Disaster</strong> <strong>Management</strong>Introduction<strong>Disaster</strong> risk management• The term ‘disaster risk management’refers to integrated multisectoral andmultidisciplinary administrative,organizational and operational planningprocesses and capacities aimed atlessening the impacts of naturalhazards and related environmental,technological and biological disasters.8/4/2012 4Improved governance through technology
<strong>Disaster</strong> <strong>Management</strong>IntroductionRISKFor the purpose of <strong>Disaster</strong> <strong>Management</strong>(<strong>Disaster</strong> Risk <strong>Management</strong>), risk isdefined as the possibility of sufferingharm from a hazard that can causeinjury, disease, economic loss orenvironmental damage. Risk can beexpressed in terms of:– A probability: a mathematicalstatement about how likely it is thatsome event or effect will occur,– Or frequency: the expected numberof events occurring in a unit time(Allen, 1992).8/4/2012 5Improved governance through technology
<strong>Disaster</strong> <strong>Management</strong>IntroductionRisk Assessment• Risk assessment involves estimatingthe probability that a hazard willoccur and the potential impact ofsuch an event.• The risk assessment processinvolves using data, hypothesesand models to estimate theprobability of harm to humanhealth, infrastructure, or to theenvironment that may result fromexposure to specific hazards (Miller,2000).8/4/2012 6Improved governance through technology
<strong>Disaster</strong> <strong>Management</strong>IntroductionHazardPhysical situation with a potential forhuman injury, damage to property,damage to the environment or somecombination of these.It is important to distinguish between theterms disaster and hazard. A potentialdamaging phenomena (hazard) only hasthe potential of becoming a disasterevent when it occurs in populated areaswhere it can cause loss of life or majoreconomical losses (Allen, 1992).8/4/2012 7Improved governance through technology
<strong>Disaster</strong> <strong>Management</strong>IntroductionVulnerability• Vulnerability can be described as set ofconditions and processes resulting fromphysical, social, economic andenvironmental factors, which mayincrease the susceptibility of acommunity or location to the impactsof hazards.8/4/2012 8Improved governance through technology
<strong>Disaster</strong> <strong>Management</strong>Undertaking <strong>Disaster</strong> Risk Assessment• Many methodologies and approachesexist– Study area– Available expertise– Resources• Financial• Other– Data• <strong>Disaster</strong> <strong>Management</strong> related• OtherThe framework provide a methodology thatmust be followed8/4/2012 9Improved governance through technology
<strong>Disaster</strong> <strong>Management</strong>Undertaking <strong>Disaster</strong> Risk AssessmentPreliminary Stage• Identify key stakeholders• Compile a project andmethodology plan• State a method or approach tointerpreted the findingsDeliverable is a document that state themethodology and possible outcome of theproposed project.This document must be previewed by NDMCbefore the project can start8/4/2012 11Improved governance through technology
<strong>Disaster</strong> <strong>Management</strong>Undertaking <strong>Disaster</strong> Risk AssessmentStage 1 – Identify specific disaster risk(s)• Identify and describe thehazard• Describe and quantifyvulnerability• Estimate likely losses• Identify relevant capacitiesWhat hazards to identify on provincial level?8/4/2012 12Improved governance through technology
<strong>Disaster</strong> <strong>Management</strong>Undertaking <strong>Disaster</strong> Risk AssessmentWhat hazards to identify on provincial level?• Likely to affect more than one District• High and medium magnitude, occur inmost districts and may require provincialsupport and/or intervention• Are of high magnitude and low frequencyoccur infrequently or seasonally, havethe potential to cause severe loss, andrequire levels of specialist support notavailable at district level• Affect neighbouring provinces and haveconsequences for the province8/4/2012 13Improved governance through technology

<strong>Disaster</strong> <strong>Management</strong>Examples of the Methods used todetermine vulnerability levels with GIS:• Distance and population size• Number and Land use type per stand• General land use type and area• Quantify Infrastructure at risk• Wards and population size8/4/2012 21Improved governance through technology
<strong>Disaster</strong> <strong>Management</strong>Examples of results• Provincial level• District or local level<strong>Disaster</strong> risk assessment information generated by nationaland provincial departments, municipalities and researchcommissions must be consolidated by the NDMC to provide aNational Indicative <strong>Disaster</strong> Risk Profile.The following two mechanisms must be used to ensure theaccuracy of the disaster risk assessment undertaken to informnational, provincial and municipal area planning:• Establishment of a technical advisory committee• External validation or external peer review of methods andfindings.At a minimum, all assessments carried out at national,provincial and municipal levels should be externally validatedwith respect to the methods used and findings generated.8/4/2012 22Improved governance through technology
