환경영향평가 협의 시 생태통로 조성을 위한 가이드라인 마련

A Study on the Guidelines for Creating Wildlife Crossing through Environmental Impact Assessment

Abstract

본 연구는 "환경영향평가 협의 시 생물이동성 제고를 위한 법 제도적 고찰에 관한 연구"의 후속연구로 환경영향평가 협의를 통하여 조성된 대부분의 생태통로가 원목적과 부합하지 않게 조성되어 야생동물 교통사고를 저감하지 못하는 문제점을 개선하고자 수행하였다. 단절된 생태계의 연결성을 회복하기 위한 대안으로 환경영향평가 시 제시한 생태통로가 실질적인 역할을 할 수 있도록 각 단계별 고려사항을 제시하였다. 따라서 본 연구에서는 환경영향평가 협의 단계를 계획, 설계, 시공, 모니터링, 유지 관리 등 5단계로 구분하여 실무담당자가 각 단계별로 검토해야하는 구체적인 항목을 제시하였다. 이로 인하여 원목적과 부합하지 않게 조성되어 야생동물에게 외면당하는 생태통로 조성을 막아 개발 사업으로 인한 서식지 단절을 최소화하고 생물다양성을 향상시킬 수 있도록 하고자 하였다.

This study found that wildlife crossing created through environmental impact assessments didn't reduce the number of wildlife accidents on the road by review of "A Study on the Legal and Institutional Review for Reproving Bio-Mobile in Environmental Impact Assessment(2018)". Specific considerations to be reviewed at each stage of the environmental impact assessment consultation were presented for practical site application. Therefore, in this study, the consultation steps for environmental impact assessment were presented in five stages, including planning, design, construction, monitoring, maintenance and management, and detail of the items to be reviewed by public officer. It will be able to prevent loss of habitats and improve biodiversity by improving the practice and institutional problems that were planned and designed at the time of construction.
