    • According to 4th IPCC(Intergovernmental Panel on Climate Change) report,climate change is altering disaster risk patterns in three main ways :Increase in frequency and intensity of extreme events, such as morefrequent extreme temperatures and heavy precipitation, more intensetropical cyclones and expanded area affected by drought and floods;Changes in geographical distribution of area affected by hazards;Global Climate ChangePrediction of Global Climate Change기후변화대응 식품안전관리 연구사업단www.climate-food.netChanges in geographical distribution of area affected by hazards;Increase in vulnerability of particular social groups and economicsectors due to sea level rise, ecosystem stress and glacier melting.Hurricane Katrina,U.S.ATsunami,AsiaEarthquakeChinaFlood,U.KHot Summer,FranceDrought,AfricaIce Melting,PeruEl Nino5
    • Global warming will accelerate with predictions of the average increase inglobal temperature ranging from 1.8 to 4℃℃℃℃(IPCC, 2007) .By 2020, between 75 and 250 million people are projected to sufferincreased water stress in sub-Saharan Africa and by 2080 2 to 7 millionmore people per year, will be affected by coastal flooding (Yohe et al., 2007).Global Climate ChangePrediction of Global Climate Change기후변화대응 식품안전관리 연구사업단www.climate-food.netOf the 262 million people affected annually by climate disasters between2000 and 2004, more than 98 percent lived in developing countries(UNISDR/CRED, 2007).6
