King County and the city of Seattle have agreed to invest in major upgrades to local sewage and combined stormwater collection, piping and treatment under settlements with the Department of Justice and the U.S Environmental Protection Agency (EPA.
Plants on the roof? A gable garden? What the heck is going on?
The University of Canterbury (UC) is investigating the benefits of green planted-roofs for the New Zealand built-environment.
Have you ever walked in a park between old industrial buildings getting a scent of the industrial era, while having a thousand things to explore?
This is a very knew area of scientific inquiry and we are just scratching the surface. However, enough successful work has been done that compels us to start incorporating these tactics and strategies in our built environment as partners in progress. Our green standards are abysmally too low for any serious self-congratulations. By using grey water as green roof and living wall irrigation now, we can start evaluating the phytoremediation effects as we go. After mechanical filtration and phytoremediation, along with control of the contaminants we introduce into our environment, I see no reason why we can’t start using green water for a wide array of uses from laundry to washing food to washing ourselves, to irrigating food crops, to irrigating green roofs and living walls in areas short on potable water.
To restore the balance in urban ecosystems, urban planners and designers have started to look for different ways to generate green spaces in an increasingly grey world. Green spaces benefit cities and their inhabitants by minimizing temperature variation, absorbing rainwater, reducing stormwater runoff and promoting biodiversity, all of which can improve the well-being of the cities inhabitants.
Robyn Simcock has just sent through recent research from NZ. 1. Enhancing plant water supply without irrigation or deeper substrates. 2. Drivers of Living Roof water quality. Both docs have been posted in the Library
