Abstract

The numbers of multi-year droughts due to climate change are increasing worldwide. Boryeong Dam, located in Chungcheongnam-do, South Korea, was also affected by a 4-year drought from 2014 to 2017. Since traditional unilateral decision making processes to alleviate drought damage have, until now, resulted in conflicts between many of the involved groups, the need for active participation from both stakeholders and policymakers is greater than before. This study introduced Shared Vision Planning, a collaborative decision making process that involves participation from various groups of stakeholders, by organizing Water Policy Council for Climate Change Adaptation in Chungcheongnam-do. A Shared Vision Planning Model was then developed with a system dynamics software by working together with relevant stakeholders to actively reflect their requests through three council meetings. Multiple simulations that included various future climate change scenarios were conducted, and future drought vulnerability analysis results of Boryeong Dam and districts, in terms of frequency, length, and magnitude, were arrived at. It was concluded that Boryeong Dam was more vulnerable to future droughts than the eight districts. While the total water deficit in the eight districts was not so significant, their water deficit in terms of spatial discordance was proved to be more problematic. In the future, possible alternatives to the model will be implemented so that stakeholders can use it to agree on a policy for possible conflict resolutions.

기후변화로 인한 다년 가뭄은 전세계적으로 증가하는 추세이며, 충청남도에 위치한 보령댐 또한 2014년부터 2017년까지 지속된 다년 가뭄으로 인해 큰 피해를 받았다. 다양한 가뭄 피해 저감 정책 설립 과정에 있어 일방적인 하향식 의사결정 과정을 바탕으로 진행된 정책은 이해당사자간의 갈등을 야기했기에, 이를 방지하기 위해서는 이해당사자와 정책결정자들간의 참여형 의사결정 과정이 필수적이다. 본 연구에서는 다양한 그룹으로 구성된 이해당사자의 참여를 독려하는 참여형 의사결정 방식 중 하나인 비전공유계획을 충청남도 기후변화 적응 물관리정책 협의회를 통해 체계적으로 적용하였다. 또한, 비전공유계획의 핵심 요소인 비전공유모형을 시스템 다이내믹스 모형으로 개발하였고, 총 3회의 소위원회를 거쳐 이해당사자의 요청사항에 맞추어 모형을 보완하였다. 구축한 모형을 활용하여 미래에 발생 가능한 가뭄의 위험을 포함하고 있는 기후변화 시나리오로 모의하였고, 보령댐과 보령댐 계통 지자체의 가뭄으로 인한 취약성을 빈도, 지속기간, 크기 개념의 평가지표로 표현하였다. 모의 결과, 용수 공급원인 보령댐은 용수 수급처인 지자체보다 가뭄에 상대적으로 더 취약하며, 8개 지자체 중 가뭄 대응 대책이 주로 계획되어 있는 지역과 모의에서 추정한 가뭄 발생 지역이 일치하지 않음을 확인하였다. 모의 결과를 향후 협의회 회의에서 이해당사자와 공유하고, 댐과 지자체의 입장에서 용수 부족을 해소할 방안을 모형에 적용함으로써 미래 정책 결정 및 갈등 해소를 위해 개발한 비전공유모형을 이용할 수 있음을 제안하였다.
