Nature-based Solutions (NbS) are actions that work with and enhance nature to help address societal challenges. The concept is grounded in the knowledge that healthy natural and managed ecosystems produce a diverse range of services on which human wellbeing depends.
NbS is an ‘umbrella concept’ for other established nature-based approaches such as ecosystem-based adaptation (EbA) and mitigation (EbM), eco-disaster risk reduction (eco-DRR), Green Infrastructure (GI) and natural climate solutions (NCS).
If you would like to learn more about the role of NbS in climate change adaptation and mitigation, please read our recent publications, “Understanding the Value and Limits of Nature-Based Solutions to Climate Change and Other Global Challenges” and “Mapping the effectiveness of nature‐based solutions for climate change adaptation“.
Meanwhile, some evidence-based guiding principles around NbS and their implementation can be read here.
Protecting or restoring forests and wetlands (e.g. peatlands) in catchments can secure and regulate water supplies, support production of forest products, and protect communities and infrastructure from floods, soil erosion and landslides.
Creating green roofs and walls and planting trees in cities can moderate the impacts of heatwaves, capture storm water and abate pollution. Such measures also have positive outcomes for mental and physical health.
Protecting or restoring coastal ecosystems (mangroves, reefs and salt marshes) protects communities and infrastructure from storm surges and erosion. Coastal habitats, especially mangroves, are particularly good at sequestering carbon, so restoration also contributes to climate change mitigation.
