Valuing the Benefits of Green Stormwater Infrastructure
This is an advance summary of a forthcoming article in the Oxford Research Encyclopedia of Environmental Science. Please check back later for the full article.
Green infrastructure, a decentralized approach for managing stormwater that uses natural systems or engineered systems that mimic the natural environment, is being adopted by cities around the world to manage stormwater runoff. Primary benefits of such systems include reduced flooding and improved water quality. Green infrastructure projects, such as green roofs, rain gardens, rain barrels, bioswales, permeable surfaces, and green streets may also generate co-benefits such as reducing the urban heat island effect, creating habitat, reducing air and water pollution, and improving human health. A summary of market and non-market valuation studies on the benefits of green infrastructure identifies gaps in the existing literature and opportunities for further study.
