This month the Landscape Institute's president Noel Farrer called for more greening of London's urban infrastructure in order to tackle it's mounting air pollution problems.
Speaking at an open conference in the run-up to the architecture festival 'Open House London' last week, Farrer flew the flag for urban design and landscaping as a major answer to climate and pollution problems.
From street trees to green roof technology and sustainable urban drainage systems (SUDS) he said; "Landscape architecture is a broad church," "It's not just about streets and parks. It is now a very holistic and complex subject."
Often biodiversity and green urban landscapes are seen as a 'nice to have'. Farrer argued instead that they are fast becoming an essential part of denser cities and are vital to combat pollution and flood risk.
Roland Grzybek of CH2MHill and the ICE, also spoke at the conference and agreed that city environments need to be considered holistically. Grzybek chairs the Thames Estuary Partnership, which is responsible for delivering the Thames Tideway Tunnel super sewer. He pointed to the concreting of front gardens as a major contributor to flooding and sewer overflow into the Thames.
The Landscape Institute is working with the ICE to help offer landscape solutions to the city's problems, from alleviating flooding through SUDS to improving air quality through planting trees.
Farrer commented that, political will would be needed to enforce policies to improve cities.
