NbS Triple Win Toolkit: Evidence Base 107 Focal areas of NbS projects in ODA-eligible countries Of the 283 projects in the Database of NbS Case Studies whichwere in ODA-eligible countries, the majority have been implementedin the (rural) terrestrial environment (n=180). Significantly fewerNbS were found to be implemented in the marine (n=67) andurban (n=36) environments. Count of Case Studies 200 150 100 50 0 Marine TerrestrialFocal Area Urban Focal Ecosystems of NbS Projects in ODA-eligible Countries The predominant ecosystem or biome in the 283 projects in ODA-eligible countries analysed was terrestrial production or artificial landscapes (n=64), mostly agriculture. Tropical and subtropical forests made up the second most common ecosystem or biome (n=45). Several projects covered ‘multiple’ ecosystems (n=33), with projects using landscape, seascape and ridge to reef approaches. Apart from coastal wetlands and mangroves, most marine ecosystems ranked among the least represented ecosystems (n=4 for Large Marine Ecosystems; n=2 for coral reefs). Grasslands (n=4 for temperate; n=4 for tropical and subtropical) and peatlands (n=2) were also seldomthe ecosystem of focus. It is important to note that, whilst some ecosystems appear underrepresented, they may be in proportionto their global extent. Focal areas of case studies assessed in ODA-eligible countries
