Summary: In this seminar we will summarize parts of the Nordic Council of Ministers four-year visions program on Nature-based solutions. The presentation will be based on two main parts, the S-UMMATION project focusing on a status overview and mapping of nature-based solutions in the Nordic countries. This includes policy framework(s), what challenges do Nordic countries experience in the process of mainstreaming NBS, and highlighting some key examples of projects implementing NBS. The methods used include a review of the academic literature, providing insights on the status of research, a grey literature review in each Nordic country, to describe the policy framework for NBS and practical implementation of NBS projects, a compilation of a Nordic NBS case projects catalogue, which contains implemented case projects using NBS in all major ecosystems: terrestrial (forests and agricultural land), freshwater, coastal and marine. The second part of the presentation will focus on the follow-up S-UMMATION project, presenting findings of practical experiences with nature-based solutions (NBS) in the Nordics. Here we will present insights from eight ongoing NBS pilot projects where we had the ambition to harvest insights to support effective and efficient implementation of NBS and to enable transferability and upscaling.  The information comes from interviews and workshops with the project leaders and team members, in addition to information from project descriptions and other written material. The findings focus on the shared key insight deriving from the pilot projects that are important for the development of NBS in the region. One of the main findings highlight the importance of involving landowners and land ownership aspects in NBS implementation.
