Nature-based solutions (NBS) are actions or measures that use or mimic the processes and functions of ecosystems to address societal challenges, such as climate change, flooding, or drought. These solutions can be used to restore or enhance ecosystems, or to create new green infrastructure that provides ecosystem services.
Here are the example of ten successful nature-based solutions from around the world:
- Costa Rica generates 99% of its electricity from renewable sources, including hydropower and geothermal energy.
- The city of Amsterdam has implemented a network of green roofs, which reduces stormwater runoff and the urban heat island effect.
- In Rwanda, the government restores and protects the country’s forests, resulting in a tree cover increase from 8% in 2005 to over 30% in 2020.
- The state of California invests in a large-scale drought prevention program, including new reservoir construction and expansions, as well as water conservation measures.
- Australia’s Great Barrier Reef protects through strict fishing regulations, marine protected areas, and damaged area restoration.
- Portland, Oregon restores and protects its urban forests, leading to increased tree canopy cover and decreased air pollution.
- Vermont reduces nutrient pollution in Lake Champlain through agricultural best management practices and upgraded wastewater treatment facilities.
- Kenya’s Maasai Mara National Reserve reduces human-wildlife conflict through elephant-proof fencing and community-owned conservancies.
- Seoul, South Korea restores and protects its urban streams, resulting in increased biodiversity and decreased flooding.
- Minnesota restores and protects its wetlands, leading to increased wildlife populations and improved water quality.
