기후변화 적응대책·기술의 지속가능성 평가방법 개발 및 적용

Abstract

Climate change is the biggest risk facing many cities today due to extreme weather phenomena such as heat waves, droughts and floods. Achieving future sustainability in despite the risks associated with climate change is the goal of climate change adaptation measures and technologies. Among climate change adaptation measures seeking to decrease climate risk, some may cause mal-adaptation that undermines sustainability in the long-term. However, there is a lack of research on assessment of the sustainability of adaptation policies. Therefore, this study develops a methodology for assessing the sustainability of climate change adaptation measures and technologies and examines the degree of sustainability of widely used adaptation measures and technologies. The developed sustainability evaluation tool consists of 90 indicators in the social, economic, ecological and governance dimensions and is based on semi-quantitative assessment. Sustainability evaluation of 52 adaptation measures in disaster, health, land and infrastructure, and coastal sectors revealed that sustainability impact scores of the disaster sector were relatively higher than those of other sectors. Most measures scored high in the social dimension, while the economic and ecological dimensions showed a significant impact on the total scores of measures. This sustainability assessment methodology for assessing adaptation measures and technologies is expected to supplement the current priority assessment based on risk-reduction effects, urgency, feasibility and cost.
