Abstract

Due to their multiple economic, social and environmental benefits, Nature-based solutions (NBS) have become an integral part of climate policy strategies, notably regarding climate adaptation. Their benefits include mitigating the heat island effect, enhancing air quality, and reducing flooding. Despite the European Union's strong adoption and promotion of NBS, diffusion varies widely among Member States. This study assesses the current EU strategies and national integration of NBS, identifying governance and financial barriers to their implementation. We combine a policy review with 19 expert interviews to explore these challenges. Our findings aim to clarify the "how" and "why" behind implementation issues, providing insights to enhance the effectiveness and uptake of NBS in Europe. We find that NBS are not systematically integrated into key policy planning tools. They face a multi-barrier structure consisting of various governance and financing barriers. Pursuing integrated approaches both in terms of public engagement and private finance seems a promising way to further develop NBS.
