NbS Triple Win Toolkit: Evidence Base 105 The case study analysis was undertaken to identify projects implementing NbS in ODA-eligible countries and, of those,which had achieved or were aiming to achieve the triple winfor biodiversity, climate and people. 2,934 projects were reviewed from 34 databases. To identify relevant case studies, all 2,934 projects were assessed as to whether they metthe definition of an NbS. Those projects that did meet this definition(792 projects) were then reviewed further using JNCC’s selection criteria: The case study demonstrated objectives which address UK Government’s (i) climate change (adaptation and/or mitigation); (ii) biodiversity loss; and (iii) poverty reduction policies. The projects could address two or more objectives directly or one directly and two indirectly. The project aims or objectives were clearly defined and indicative of positive future impacts. There was sufficient information provided about the case study to complete a more in-depth review. The project must be active or completed. Cancelled projects were not reviewed. Case study analysis Those projects which met both the definition of an NbS and the selection criteria (378 projects) were then subject to a detailed assessment. Two databases were produced to summarise theavailable information and assessments. The ‘Database of NbS Case Studies’ contains information on the projects (378) that met both the definition of an NbS and the selection criteria. This database provides a range of information on each case study, including the geographic location, the NbS intervention typeand an assessment of whether the project had achieved or wasaiming to achieve the ‘triple win’ for biodiversity, climate and people. The ‘Library of Projects’ contains all 2,934 projects assessedfor this Project. The project title, the database it is hosted in anda link are provided, as well as whether the project incorporateda clearly defined NbS. Summaries of 12 NbS case studies selected from the Databaseof NbS Case Studies are provided.
