Recently, climate change risk assessment has been discussed as a medium process for making climate change adaptation policies in the research field of climate change adaptation. Climate change risk assessment has been understood to have an intermediary role among impact assessment, vulnerable assessment and policy, and is used in the process of devising adaptation policies in the United Kingdom (UK). This paper quantitatively assessed the risks of climate change in Korea, applied the methods used in the UK, underwent the classification process and suggested implications of Korean adaptation policies. A survey of experts, based on Delphi's method and the classification criterion developed by Klinke and Renn(2002), was also carried out. A list of climate risks was created from the climate change impact and vulnerability assessment report of Korea, first national adaptation policy of Korea, and general climate risks of the UK. From the results, 42 risks out of total 125 risks were selected based on their importance. The assessed risks with factors, such as high impact and urgency, are related to repeated and large scale damage from storms and floods caused by abnormal or extreme weather events. Ecological changes and social infrastructure risks were engaged as required as a policy response for medium to longer term. As for making the classification, types of climate risks were suggested to manage the basic capacity in relation to social trust, triggering mechanism and responsibility. Following suggestions are put forward as the base of autonomous adaptation: increasing the capacity of civil society, mutual trust and civil participation in adaptation policy process.

Given the presence of global warming, the economic impact of climate changes on output sales has been discussed in the literature, but rarely with empirical evidences. In this present study, a simple log-model was employed to identify the economic impacts of weather changes in manufacturing and service sectors in Korea. For this empirical exercise, weather variables including the CDD (cooling degree days) and HDD (heating degree days) were computed using the Korea's meteorological records covering the period 1970-2012. According to estimation results, 26.7% (144 over 539) and 27.9% (64 over 229) of the manufacturing and service sectors, respectively, are found to be weather-sensitive.

도시화와 산업화, 그리고 인구 증가 등은 우리사회에 기후변화라는 재앙으로 다가오고 있다. 그리고 이러한 기후변화는 기업에 영향을 미치어 경영환경의 불확실성을 높이고 있다. 즉, 기후변화는 기업이 경영함에 있어 물 공급의 부족 등과 같은 물리적 리스크를 제공하는가 하면 요구 기술의 변화, 시장의 변화 등 전환 리스크(transition risk)로 작용하여 기존 제품 및 서비스의 생존을 어렵게 하는가 하면 기업의 자산 가치에 변화를 주고 있다. 이에 본 연구는 기후변화로 인한 시장환경 변화에 글로벌 기업들이 어떻게 대응하고 있는가를 검토·시사점을 제시하였다. 기후변화가 기업에 미치는 영향은 단순히 위기로만 다가오지 않는다. 기후변화는 기업에게 물부족 등의 물리적 위험과 사회적 규제, 새로운 기술 수요 등 리스크로써 영향을 미치는 한편 탄소 시장 형성 등의 기회로도 작용하고 있다. 이에 글로벌 기업들은 위기이자 기회인 환경의 변화에 대응하여 'ESG 성과 측정'을 도입, 대응하는 사례가 증가하고 있다. 사례로는 투자기관인 골드만삭스에서 기후변화 대응을 정부규제, 이해관계자, 경쟁환경 변화 등 3가지 관점에서 대응하는가 하면 독일계 화학회사인 BASF는 기업의 사회적 가치를 ESG 요소의 관점에서 평가하여 매년 발표하고 있다. 한편 국내 기업으로는 SK그룹이 대표적인데, 동사는 사회적 가치 평가 결과를 임직원 핵심성과지표(KPI)에 반영함으로써 경영현장에서도 사회적 가치를 고려하도록 시스템화하고 있다.

This study assessed urban flood risk using a Bayesian probability statistical method and GIS incorporating a climate change scenario. Risk is assessed based on a combination of hazard probability and its consequences, the degree of impact. Flood probability was calculated on the basis of a Bayesian model and future flood occurrence likelihoods were estimated using climate change scenario data. The flood impacts include human and property damage. Focusing on Seocho-gu, Seoul, the findings are as follows. Current flood probability is high in areas near rivers, as well as low lying and impervious areas, such as Seocho-dong and Banpo-dong. Flood risk areas are predicted to increase by a multiple of 1.3 from 2030 to 2050. Risk assessment results generally show that human risk is relatively high in high-rise residential zones, whereas property risk is high in commercial zones. The magnitude of property damage risk for 2050 increased by 6.6% compared to 2030. The proposed flood risk assessment method provides detailed spatial results that will contribute to decision making for disaster mitigation.

최근 지구온난화와 기후변화에 의한 가뭄과 홍수의 발생빈도가 증가하고 있는 상황이며 기후변화에 의한 재해는 사회시설과 국민생활에 직접적, 간접적 영향을 미칠 수 있기 때문에 전세계적으로 홍수에 관한 다양한 연구가 진행중에 있다. 본 논문에서는 홍수의 정확한 구조적 대책을 수립하기 위해 공간정보를 활용하여 FLO-2D를 이용한 홍수 범람 모의를 실시하고 그 결과를 토대로 ILWIS를 이용한 홍수 리스크 분석을 실시하였다.

Recently, the frequency and intensity of heat waves due to the increase in climate change temperature are increasing. Therefore, this study tried to compare the evaluation process and evaluation results of the heat wave disaster evaluation, which is the government's analysis of the heat wave disaster vulnerability and the risk evaluation method recently emphasized by the IPCC. The analysis of climate change disaster vulnerability is evaluated based on manuals and guidelines prepared by the government. Risk evaluation can be evaluated as the product of the possibility of a disaster and its impact, and it is evaluated using the Markov chain Monte Carlo simulation based on Bayesian estimation method, which uses prior information to infer posterior probability. As a result of the analysis, the two evaluation results for Busan Metropolitan City differed slightly in the spatial distribution of areas vulnerable to heat waves. In order to properly evaluate disaster vulnerable areas due to climate change, the process and results of climate change disaster vulnerability analysis and risk assessment must be reviewed, and consider each methodology and countermeasures must be prepared.

This study aims at deriving the implications for adaptation policy and research target regarding climate change risk assessment in ecosystem sector in Korea. The common ground of exemplary cases of "world leaders" in terms of adaptation policies and researches was that they emphasize nationwide study on climate change on biodiversity and ecosystem in target of establishing scientific evidence-bases and reducing uncertainty for their national adaptation policies and plans. In light of this trend, Korean government should settle down more successful adaptation structure by leading adaptation system in further national policy-settings to observe UNFCCC and CBD integratedly and effectively, considering the economic value of adaptation in policy, and strengthening scientific research programs and technology developments. Moreover, risks assessment based on diagnoses and analysis on the risk factors (hazard, exposure, and vulnerability) for climate change in nationwide habitats and species and consolidations with subsequent adaptation strategies could make adaptations in ecosystem sector more effective and successful.
