Abstract

This study was conducted to provide basic data that can be used when establishing Net Zero policies and implementation plans for non-urban settlements by quantitatively analyzing the Net Zero contribution to green infrastructure in rural areas corresponding to non-urban settlements. The main purpose is to first, systematize green infrastructure in rural areas, secondly derive basic units for each element of green infrastructure, and thirdly quantify and present the impact on Net Zero in Korea using these. In this study, CVR(Content Validity Ration) analysis was performed to verify the adequacy of green infrastructure elements in rural areas derived through research and analysis of previous studies, is as follows. First, Hubs of Green infrastructure in rural area include village forests, wetlands, farm land, and smart farms with a CVR value of .500 or higher. And Links of Green infrastructure in rural area include streams, village green areas, and LID (rainwater recycling). Second, the basic unit for each green infrastructure element was presented by classifying it into minimum, maximum, and median values using the results of previous studies so that it could be used for spatial planning and design for Net Zero. Third, when Green infrastructure in rural areas is applied to non-urban settlements in Korea, it is analyzed that it has the effect of indirectly reducing CO2 by at least 70.76 million tons and up to 141.16 million tons. This is 3.4 to 6.7 times the amount of CO2 emission from the agricultural sector in 2019, and it can be seen that the contribution to Net Zero is very high. It is expected to greatly contribute to the transformation of the ecosystem. This study quantitatively presented the carbon-neutral contribution to settlements located in non-urban areas, and by deriving the carbon reduction unit for each element of green infrastructure in rural areas, it can be used in spatial planning and design for carbon-neutral at the village level. It has significance as a basic research. In particular, the basic unit of carbon reduction for each green infrastructure factors will be usable for Net Zero policy at the village level, presenting a quantitative target when establishing a plan, and checking whether or not it has been achieved. In addition, based on this, it will be possible to expand and apply Net Zero at regional and city units such as cities, counties, and districts.

본 연구는 비도시 정주지에 해당하는 농촌지역 그린인프라에 대한 탄소중립 기여도를 정량적으로 분석하여 비도시 정주지에 대한 탄소중립 정책 및 이행방안 수립시 활용할 수 있는 기초자료를 제공하기 위하여 진행하였다. 주요 목적은 첫째, 농촌지역 그린인프라를 체계화하고, 둘째, 그린인프라 요소별 원단위를 도출하며, 셋째, 이를 활용하여 우리나라의 탄소중립에 미치는 영향을 정량화하여 제시하는 것이다. 본 연구에서는 선행연구 조사 및 분석을 통해 도출된 농촌지역 그린인프라 요소에 대한 적정성 검증을 위하여 내용 타당도(CVR) 분석을 실시하였고 그린인프라 요소별 탄소감축량 원단위는 관련 분야 연구 결과를 활용하였으며 그 결과는 다음과 같다. 첫째, 농촌지역 핵심기능(Hubs)의 그린인프라는 마을숲, 습지, 농경지, 스마트팜, 연결기능(Links)은 하천, 마을녹지, 빗물 재활용시설이 .500 이상의 CVR값을 가지는 것으로 나타나 적정한 것으로 분석되었다. 둘째, 그린인프라 요소별 원단위는 선행연구 결과를 활용하여 최소값, 최대값, 중간값으로 구분 제시하여 탄소중립을 위한 공간적 계획, 설계 등에 활용될 수 있도록 하였다. 셋째, 농촌지역 그린인프라를 우리나라 비도시지역 정주지에 적용할 경우 최소 70.76 백만 톤, 최대 141.16 백만 톤에 달하는 CO2 를 간접적으로 감축하는 효과가 있는 것으로 분석되었다. 이는 2019년 농업부문 탄소배출량의 3.4배에서 6.7배에 달하는 양으로 탄소중립 기여도가 매우 높다고 볼 수 있으며, 이를 활용한 경제적 가치는 최소 약 1조 6천억 원에 달하여 농촌지역 활성화, 녹색일자리 창출, 농촌 산업생태계 전환 등에도 크게 기여할 수 있을 것으로 예상된다. 본 연구는 비도시지역의 정주지에 대한 탄소중립 기여도를 정량적으로 제시하였으며, 농촌지역 그린인프라 각 요소별 탄소감축 원단위를 도출함에 따라 마을단위의 탄소중립을 위한 공간적 계획, 설계 시 활용할 수 있는 기초연구로서 의의를 가진다. 특히, 그린인프라 요소별 탄소감축 원단위는 마을단위 탄소중립 정책, 계획 수립 시 정량적 목표제시 및 달성 여부 점검 등에 활용가능할 것이며 이를 기반으로 하여 시군구 등 지역단위와 도시단위의 탄소중립화에 확대 적용할 수 있을 것이다.
