Create blue-green cities
01 December 2016 - Published by Ellen Kelder
Blue and Green Infrastructures (BGI) comprises an approach to climate resilience for cities that mimics nature’s potential to deal with flooding. BGI supports existing grey infrastructure to cope with extreme weather events (reducing flood risk by 30%) and improves urban liveability. Research (TEEB, 2015) shows that BGI benefits outweigh costs by a factor of 2 to 10. However, widespread implementation is hampered by financial and governance complexities.
