Concept
Nature-based solutions
Summary
Nature-based solutions (NBS) is the sustainable management and use of natural features and processes to tackle socio-environmental issues. These issues include climate change (mitigation and adaptation), water security, water pollution, food security, human health, biodiversity loss, and disaster risk management. The European Commission's definition of NBS states that these solutions are "inspired and supported by nature, which are cost-effective, simultaneously provide environmental, social and economic benefits and help build resilience. Such solutions bring more, and more diverse, nature and natural features and processes into cities, landscapes, and seascapes, through locally adapted, resource-efficient and systemic interventions". In 2020, the EC definition was updated to further emphasise that “Nature-based solutions must benefit biodiversity and support the delivery of a range of ecosystem services.” Through the use of NBS healthy, resilient, and diverse ecosystems (whether natural, managed, or newly created) can provide solutions for the benefit of both societies and overall biodiversity.
For instance, the restoration and/or protection of mangroves along coastlines utilizes a Nature-based solution to accomplish several goals. Mangroves moderate the impact of waves and wind on coastal settlements or cities and sequester CO2. They also provide nursery zones for marine life that can be the basis for sustaining fisheries on which local populations may depend. Additionally, mangrove forests can help to control coastal erosion resulting from sea level rise. Similarly, green roofs or walls are Nature-based solutions that can be implemented in cities to moderate the impact of high temperatures, capture storm water, abate pollution, and act as carbon sinks, while simultaneously enhancing biodiversity.
Conservation approaches and environmental management initiatives have been carried out for decades. More recently, progress has been made in better articulating the benefits Nature-based solutions can provide for human well-being.
