NbS Triple Win Toolkit: Evidence Base 110 Spread of NbS projects in ODA-eligible countries The map shows the geographic distribution of projects in the Database of NbS Case Studies which were in ODA-eligible countries (283 projects). The distributions of projects underscore how NbS are globally applicable, but with differential uptake in different areas. Any apparent gaps – such as in North Africa or the Middle East – would need to be properly investigated before suggested for prioritisation. Implementation of NbS interventions assessed The figure provides the earliest start date and latest end date ofproject implementation for each NbS intervention type with fiveor more projects recorded. This illustrates how terminology evolves through time. It does not implythat these interventions have only been used over the indicated time periods. It also highlights that some terms which fall under theumbrella of NbS have been more commonly used for longerthan others, e.g. ‘Reforestation’ vs. ‘Eco-DRR’.
