How do nature-based solutions improve environmental and socio-economic resilience to achieve the sustainable development goals? Reforestation and afforestation cases from the republic of korea

Industrial and technological development have contributed significantly to causing environmental crises, such as climate change and land degradation. To address these environmental challenges, nature-based solutions (NBS) have gained increased attention over conventional technical responses. This study derived conceptual linkages from NBS application to resilience promotion, and subsequently, to the achievement of sustainable development goals (SDGs). The study was conducted to reveal that NBS activities are an essential approach that determines the balance between human development and nature conservation. In this paper, we compare four case studies, one domestic reforestation project and three international afforestation projects, all of which had forest-related NBS experiences and were conducted by the Republic of Korea. All four projects were found to have an impact on environmental and socio-economic resilience. These impacts were qualitatively assessed through resilience indicator evaluations. Subsequently, the resilience indicators were matched with the targets of the SDGs. NBS initiatives designed to include various natural and social elements promoted the resilience of ecosystems and society and address a broader spectrum of SDGs. Further efforts to establish region-specific promotional models, identify resilience indicators, and collect scientific data are recommended for quantitatively assessing the NBS initiatives.
