Nature-based solutions (NBS) involved conservation or rehabilitation of natural ecosystems or the creation of natural processes in modified or artificial ecosystems to mimic natural processes for the improved management of water (UN-Water, 2018). This study investigated the relationship between microbial presence and survival to the pollutant treatment performance of seven different stormwater NBS managing urban stormwater runoff. In this study, seven different stormwater nature-based solution (NBS) was investigated to identify the relationship of microbial community to the pollutant removal performance of stormwater NBS. Based on this study, Proteobacteria was found to be the most dominant microorganism for all stormwater NBS and IS followed by Acidobacteria and Actinobacteria. Acidobacteria, Actinobacteria, Chloroflexi, Gemmatimonadetes, WS3, and AF234118_p were found to have high positive correlation to most pollutant removal efficiency of different stormwater NBS (r-value: 0.62 to 0.68). Using Proteobacteria and Acidobacteria count in stormwater NBS, equations predicting pollutant removal performance were also developed and may be used in minimizing the cost for stormevent monitoring to identify the pollutant removal performance of stormwater NBS.

Floods are the most common natural disasters and are annually causing severe destructions worldwide. Human activities, along with expected increased extreme precipitation patterns as a result of climate change enhance the future potential of floods. There are proven evidence that infrastructure based responses to flood disaster is no longer achieving optimum mitigation and have created a false sense of security. Nature-based solutions(NBS) is a widely accepted sustainable and efficient approach for disaster risk reduction and involves the protection, restoration, or management of natural and semi-natural ecosystems to tackle the climate and natural crisis. Adoption of NBS in decision-making, especially in developing nations is limited due to a lack of sufficient scenario-based studies, research, and technical knowledge. This study explores the knowledge gap and challenges on NBS adoption with case study of developing nation, specially for flood management, by the study of multiple scenario analysis in the context of climate, land-use change, and policies. Identification and quantification of the strength of natural ecosystems for flood resilience and water management can help to prioritize NBS in policymaking leading to sustainable measures for integrated flood management.

Purpose: NBS (Natural-based Solutions) characteristics as eco-friendly hotels were divided into eco-friendly indoor and outdoor to structurally verify the relationship between customers' perceived eco-friendly value, psychological well-being, customer satisfaction, and pro-environmental behavioral intention. Research design, data and methodology: This survey conducted responses to customers who had experience using eco-friendly hotels for the past two years. SPSS 22.0 and AMOS 22.0 statistical programs were used for the collected questionnaire data. First, frequency analysis and confirmatory factor analysis (CFA) were verified, and structural correlation between variables was verified by covariance matrix structural equation (CB-SEM). Result: First, NBS was found to have a significant positive (+) effect on perceived eco-friendly value and psychological well-being. Second, psychological well-being was found to have a significant positive (+) effect on customer satisfaction and eco-friendly behavioral intention. Finally, Hypothesis 3 was accepted as perceived eco-value showed a significant positive (+) effect on eco-friendly behavioral intention, but Hypothesis 2 was rejected because it did not have a significant effect on customer satisfaction. Conclusions: theoretical and practical implications for the impact of NBS as an eco-friendly hotel on customers' eco-friendly behavior can be provided, as well as basic evidence for establishing efficient management strategies for hotel companies.

전 세계적으로 기후변화에 대응하기 위해 탄소중립 달성을 위한 전략 중 하나인 생태계와 생태자원을 활용하여 탄소를 저감하는 자연기반해법 방안에 관한 연구들이 진행되고 있다. 본 연구에서는 생태계서비스 기반의 평가 모델인 InVEST Carbon, Coastal Blue Carbon 모델을 이용하여 부산 연안 육역과 연안 해역을 대상으로 탄소저장량 추정 및 경제적 가치 평가를 진행하였다. 연구 결과 부산 연안 육역은 부산 전체 육역과 비교하여 단위면적당 탄소저장량이 적으며, 현재 추진 중이거나 계획된 개발이 완료되면 탄소저장량은 더 감소할 것으로 나타났다. 연안 해역은 육역과 비교해 탄소저장량이 적은 것으로 나타났지만, 향후 생태자원을 활용하는 자연기반해법의 잠재성은 크다. 하지만 공유수면 매립과 같은 개발 행위로 탄소저장량이 많은 중요 서식지에 영향을 줄 경우, 탄소저장량의 감소를 초래하며 이러한 부정적인 영향이 장기적으로 지속될 수 있는 것으로 나타났다. 따라서 부산 연안역의 지속가능한 관리를 위하여 탄소저장량을 고려한 생태계서비스 기반의 관리 전략이 필요하다.
