"The 21st-century green city is possible. Instead of relying heavily on pipes and concrete, this new approach relies upon soil, trees and open space to naturally absorb, store, evaporate and filter rainwater," says Calvin Sandborn.
"When much of California is facing drought and limited water supplies, capturing and reusing every drop of water will not only be clever, but crucial. By moving water away from the people and places that need it, stormwater cannot percolate into the ground and replenish water we keep drilling deeper and deeper to reach. Californians can counteract the negative impacts of stormwater runoff by promoting water infiltration," wrote Paula Luu.
The goal is to turn local governments on to the practical reality that designing with nature holds out hope for communities and cities to function better, to our lasting benefit. "As the leaders appointed to design the Sustainable Region Initiative, we view you as critical partners in affecting positive change with regard to infrastructure design in the region," stated Mayor Goldsmith-Jones in December 2006 at a Metro Vancouver Sustainability Community Breakfast.
“To ensure the value of green infrastructure is recognised, our research found a connection between canopy coverage and the value of Australia’s favourite investment, the family home," stated Roger Swinbourne. “The irony here is that the very development that often leads to the removal of trees suffers in the long run as the ‘double whammy’ of direct sunlight and more surface water increases maintenance frequency and cost.”
“Collaboration with Forester University means the Partnership for Water Sustainability will have created an online teaching resource that will keep on giving,” stated Richard Boase. “As a teaching tool, the webcast is intended to help these professionals ask the right questions. We would like them to focus on how they and others can apply science-based understanding, properly and effectively, turn the clock back."
"Unlike the built environment, healthy ecological services are self-sustaining, and don’t require expensive operations and maintenance costs. The ecological services provided by wetlands, aquifers, and community forests support stormwater management, drinking water protection, and climate change mitigation, all key issues for municipalities in BC," wrote David Allen.
Commencing in 2003, consistent and repeated use of the phrase ‘design with nature’ has proven effective in facilitating a paradigm-shift in the local government setting. The phrase is borrowed from the title of a seminal book by Ian McHarg, published in 1969. His book Design with Nature pioneered the concept of ecological planning. Ian McHarg’s premise is simple: “that the shaping of land for human use ought to be based on an understanding of natural process.”
“Delivering green cities requires integrated and coordinated action by councils, urban water authorities, state governments and private industry, so it’s encouraging to hear that the Federal Government will develop a vision for greener Australian cities and work with the States to implement this vision," said Jurg Keller of the Cooperative Research Centre for Water Sensitive Cities at the University of Queensland.
“Healthier watersheds can handle high and low rainfall better, and are therefore more resilient to the coming changes," stated Kris La Rose. "From the regional perspective, mitigation of flood risk, water conservation and restoration and protection of our streams and rivers are all key priorities. The increase in extreme weather is highlighting the need to build better resiliency into the natural systems that we all rely so heavily upon."
For the last 50 years, heavy rain events have been happening more frequently across the Midwest. “It’s not a large increase, but it’s measurable, We’re going to have to build our systems to be more resilient to basically cope with changing variability. Variability is a key, key issue for us as a society," says Jeffrey Andresen.
