NbS Key Facts” refers to evidence-based information about the benefits, features and outcomes associated with nature-based solutions (NbS) to address environmental, societal and financial challenges. These facts include quantifiable data, statistics and information related to the effectiveness and impact of specific NbS, and how they contribute to overall environmental sustainability.
We’re in the process of moving NetworkNature to a new and improved web-platform, and the Key Facts are coming with us!
If you’d like to add some NbS facts of your own in the meantime, please use this easy online form.

| Like inland wetlands, mangrove forests are a globally important carbon sink, with high soil and aboveground carbon densities that often exceed 1,000 tons CO2 per ha. For example, for Indonesian mangroves, on average, carbon density is estimated at 1,083 tons CO2 per ha (Mudiyarso et al. 2015). Mangrove restoration, particularly involving the establishment of mangrove trees, is highly productive and results in high removal rates estimated at 23.1 ton CO2 per ha per year during the first 20 years of growth and remaining high at 10.5 tons CO2 per ha per year, during the lifetime of mangrove stands. | Biodiversity enhancement and ecosystem restoration | Coastal, shelf and open ocean | National and EU policy-makers |

| Rivers and streams renaturation is an NBS delivering multiple benefits. The renaturation of a river in an urban park in Singapore increased the presence of biodiversity by 30%. No wildlife was introduced to the park, but the presence of the naturalized river has seen the park’s biodiversity increased by 30%. A total of 66 species of wildflower, 59 species of birds and 22 species of dragonfly have been since identified. | Biodiversity enhancement and ecosystem restoration | Urban ecosystems | Local and sub-national governments and their public authorities |
