Abstract

Discussions for water resources vulnerability and index development with sustainable concept are actively being made in recent years. Based on such index, water resources vulnerability of present and future is determined and diagnosed. This study calculated the water resources vulnerability rankings by 152 nations, using indicator related to water resources assessment that can be obtained from World Bank, VRI (Vulnerability Resilience Indicator), ESI (Environmental Sustainability Index). In order to quantitatively assess of water resources vulnerability based on this indicator, TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) technique was applied to index water vulnerability and to determine the rankings by nations. As a results, South Korea was ranked as the 88th among the 152 nations including Korea. Among the continents, Oceania was the least vulnerable and Afirica was the most vulnerable in continents. WUnited State, Japan, Korea and China were vulnerable in order among the major countries. Therefore, water resources vulnerability rankings by nations in this study helps us to better understand the situation of South Korea and provide the data for water resources planning and measure.

최근 수자원 취약성에 대한 논의 및 지속 가능한 개발개념에 적합한 지수 개발이 활발히 이루어지고 있다. 이러한 지수를 바탕으로 현재 또는 미래의 수자원 취약성을 판단하고 진단하고 있다. 본 연구는 자료의 확보가 가능한World Bank, 취약성-탄력성지수(Vulnerability Resilience Indicator, VRI), 환경지속 가능성지수(Environmental Sustainability Index, ESI)에서 사용된 수자원 평가 관련 지표들을 활용하여 우리나라를 포함한 전 세계 152개 국가의 수자원 취약성 순위를 도출했다. 이러한 지표를 바탕으로 수자원 취약성의 정량적 평가를 위해 TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) 기법을 적용하여 국가 별 수자원 취약성을 지수화하고 취약성 순위를 도출하였다. 연구결과 우리나라는 152개국 중 88위로 나타났고, 대륙 별 비교 시 오세아니아가 취약성이 낮았고, 아프리카는 취약성이 심각한 것으로 나타났다. 주요 국가 비교 시, 미국, 일본, 우리나라, 중국 순으로 취약성의 정도가 심각했다. 따라서 본 연구는 국가 별 수자원 취약성 순위를 통해 우리나라의 상황을 파악하고 국가의 수자원 계획 수립 및 대책을 제시할 수 있는 자료로 활용될 수 있을 것이다.
