Abstract

We’ve compared and conceptually evaluated the newly emerging concept of nature-based solutions (NbS’s), in the aspect of water management, and existing similar solutions of different naming, all of which are based on ecosystem functions. In this study, it is found that NbS’s seem significant and meaningful both educationally and understandably in the aspect that it can comprehensively cover and include the existing methodologies and solutions using the functions of natural ecosystem to socio-environmental challenges. It, however, seems not quite different from the broad-meaning of green infra, including Eco-DRR, in terms of the approaching methodologies in water management. The conceptual and spatial hierarchy of each practice in water management considered in this study can be expressed in the narrowing order of NbS- (EE)-BGI-(CRT)-GI-LID. Last, the term LID, which is the best management practice for storm water management in the development project, can be replaced with the term GI for clarification and less confusion both in academia and practice.

Keywords
Blue-green Infra (BGI)
Close-to-nature river techniques (CRT)
Ecological engineering (EE)
Ecological function and services
Green infra (GI)
Low impact development (LID)
Nature-based solutions (NbS’s)

본 연구는 사회환경적 문제의 해결방안으로서 새롭게 등장한 자연기반해법 (NbS) 개념을 물관리에 초점을 맞추어 생태계에 기반을 둔 기존 유사개념들과 비교, 평가한 것이다. NbS는 (자연)생태계 기능이 사회환경문제 해결에 활용하기 위한 기존의 다양한 접근방법들을 포괄적으로 대표할 수 있다는 점에서 그 의미가 있으며, 특히 교육적, 설득적인 면에서 유익한 개념이다. 그러나 물관리 측면에서 접근방법론은 특히 Eco-DRR을 포함하는 광의의 그린인프라와 실제 크게 다르지 않다. 다만 협의의 그린인프라는 현재 우수관리에 초점을 맞추고 있기 때문에 NbS 개념은 여전히 유용하다. 물관련 제 방법론은 개념적, 공간적 포괄성 관점에서 NbS-(EE)-BGI-(CRT)-GI-LID 순으로 표시할 수 있다. 마지막으로, LID 용어는 토지개발사업과 같이 특정한 경우를 제외하고 혼돈스럽지 않도록 그린인프라 용어로 대체할 수 있을 것이다.
