From “Environmental contribution of Tennessee’s urban trees: $80 billion” by James Holloway:
A study published by the US Forest service values the State of Tennessee’s urban forest at $80 billion thanks to its contributions to the environment. With an urban population of 284 million, that equates to a mean value of $282 per tree.
The total is based on a number of costs that are to some extent offset by the presence of Tennessee’s urban forest (its urban tree population, in other words). These include $350 million-worth of carbon storage based on the current standing stock, over $204 million every year in pollution removal, $18.4 million per year in additional carbon sequestration, and $66 million per year in energy savings-“the most significant contribution” made by the urban forest, according to State Forester Steven G. Scott. But how are the environmental benefits of the trees evaluated?
Data was collected and analyzed using the Forest Service’s own i-Tree Eco software. Using a mobile app providing strict protocols for data collection, researchers took information from 2418 trees and saplings across 255 field plots. Variables noted include species, diameter at breast height (or DBH—taken at 1.4 meters above ground), height, crown dimensions, foliage transparency, damage, and proximity to buildings. The pool of sample data is assumed to be representative of the total population, and from there the software crunches the numbers using “peer-reviewed equations” to paint a macro-scale picture of the urban forest, based on quantifiable characteristics that describe its structure, condition and function.

From “A Design that Celebrates the People”: Normal, IL Traffic Circle Wins Smart Growth Award as New Civic Space” by Colleen Gentles:
[In December last year], EPA announced the winners of the 2011 National Award for Smart Growth Achievement. We are excited to report that Normal, Illinois is the recipient of the award in the Civic Places category for their traffic roundabout.
We’ve written before about how the town’s new traffic circle has successfully managed traffic flow at a busy five-way intersection, diverted thousands of gallons of untreated stormwater away from the nearby creek, and become the town center by bringing residents together in an attractive public space. The more recent news is how the traffic roundabout is spurring local economic development with the construction of a multimodal transportation station adjacent to the circle, courtesy of a U.S. Department of Transportation grant. Both the transportation hub, which will eventually have high-speed rail service and create an estimated 400-500 new jobs, and the circle take advantage of the town’s existing infrastructure, bus service, and the historic central business district to attract even more residents to the new town center.
“The one-third-acre roundabout does much more than move cars. It invites pedestrians with shade trees, benches, lighting, bike parking, green space, and a water feature. People have lunch, read, and play music, and the open space invites community gatherings such as a holiday caroling event. It is the anchor for a community-wide revitalization and is part of Uptown Normal’s LEED-ND Silver recognition.
A popular rails-to-trails conversion, the Constitution Trail, leads to and around the roundabout, helping both to revitalize Normal and to bring people from surrounding areas to Normal’s central district. A new Children’s Discovery Museum on the edge of the roundabout already receives over 140,000 visitors per year, and a hotel and conference enter have recently opened nearby. One indication of the success of the redevelopment is that property values in the district have increased by about 30 percent since 2004.” Smart Growth Awards
According to the short video, this traffic circle was almost banned to pedestrians. It’s a good thing town officials fought back. [Watching the video, it looks like there are weekly farmers markets held on the roundabout too. KA]

The roundabout was designed by Hoerr Schaudt Landscape Architects. Check out their site for more photos and project details.

Wouldn’t you love to make play objects, kid’s costumes, furniture, decorations for the home and well, just about anything you can think of from the materials around you? makedo makes it possible and impossibly fun. makedo is a connector system that enables materials including cardboard, plastic and fabric to easily join together to form new objects or structures. When you’re done playing, simply pull it apart to reuse over and over again.
Box Play for Kids:
We make eco-friendly, 100% recycled, custom-designed stickers* that (combined with a little imagination) turn any old box into a wonderland of possibilities. Good for the imagination. Good for the earth. Good for the pocketbook.

Our backyards are home to a wealth of gardens and fruit trees, many of which bear more produce than the gardener can consume, or more at one time than is desired. Often people end up with piles of unwanted zucchini, plums falling off trees to rot on the ground, peas that grow old and hard before they can be picked and shelled, and other garden produce that goes to waste. At FoodPool, we see the “problem” of excess garden abundance as an opportunity! It is an opportunity to help provide those in need with fresh, ripe, homegrown produce. The only obstacle lies in linking growers with their hungry neighbors.
Our answer is FoodPooling. Our mission is to create small, local groups to gather backyard garden produce and deliver it to food banks and food pantries. These “FoodPools” are modeled on carpools – neighborhood based, easy to set up, and a big win for everyone involved! By creating numerous small, local groups, we feed our neighbors while strengthening our communities.
Through the influence of people like Michelle Obama, Michael Pollan, Alice Waters, and many others, more and more people are returning to growing fruits and vegetables in their yards. At the same time, due to a host of factors, there is an ever increasing number of Americans going hungry, eating food of questionable nutritional value, and without access to quality produce. Now more than ever there is a real need for a garden produce donation program on a national scale – hence, FoodPool.
There are already groups gleaning produce in various places – groups whose work we heartily applaud. What makes FoodPool different from existing organizations that gather and donate fruit and/or vegetables is our goal of actively building a network of new gleaning groups in places where they don’t already exist. We seek to spread the notion of assisting the hungry with backyard produce through promotion of this FoodPool “brand” on a national scale.

Permaculture designer Jason Gerhardt and his partner moved from the country into a city apartment in Boulder, Colorado, just over a year ago. While they appreciated being in a home which had a smaller footprint and connected to local markets and bike access, the loss of food-growing space presented a challenge at first:
“The biggest challenge was how I was going to come up with 50 large containers to grow food in. We had 4-5 large containers that we used to grow tomatoes in in the mountains, but nothing more. The design for the containers was rather specific in that they needed to be large enough to support the growth of crops like peppers, tomatoes, zucchini, cabbages, etc. We also need the containers to be light in color so as not to over heat from the strong direct sun that our climate affords us. Lastly, I needed the containers to be attractive so my neighbors and the homeowners association wouldn’t cause a stir. I began to search online trading posts such as craigslist, but only acquired three big containers that way. These were nice ceramic and wooden containers, but too expensive to furnish the whole patio with. I then happened upon a huge supply of full sized 5 gallon buckets from a mead maker in an industrial strip down the road. I realized they weren’t the most attractive option, but they were free, salvaged from the wastestream, light in color, and large enough. I decided to use the buckets on my private patio area and put the more attractive containers down by the street and in view of the public.”

Design with the Other 90%: CITIES features sixty projects, proposals, and solutions that address the complex issues arising from the unprecedented rise of informal settlements in emerging and developing economies. Divided into six themes—Exchange, Reveal, Adapt, Include, Prosper and Access—to help orient the visitor, the exhibition shines the spotlight on communities, designers, architects, and private, civic, and public organizations that are working together to formulate innovative approaches to urban planning, affordable housing, entrepreneurship, nonformal education, public health, and more.
Design with the Other 90%: CITIES is the second in a series of themed exhibitions that demonstrate how design can be a dynamic force in transforming and, in many cases, saving lives. The first exhibition, in 2007, Design for the Other 90%, focused on design solutions that addressed the most basic needs of the 90% of the world’s population not traditionally served by professional designers.
Organized by Smithsonian’s Cooper-Hewitt, National Design Museum, Design with the Other 90%: CITIES will be on view at the United Nations in New York City from October 17,2011 through January 9, 2012, and is available to travel in the United States and internationally beginning February 2012.

From “Suburban Dryland Forest Garden” on Permacultureglobal:
I love the forest, but I live in the city. Since I don’t get to the wildlands nearly enough, my goal has been to create an edible forest throughout the city where I live. To me, it only makes sense to grow food where people live, and since a gargantuan number of people live in cities, it’s due time to get urban food systems established. Having worked in large scale annual agriculture I’m much more inclined to grow food in the semblance of a perennial forest. […]
There were many challenges to contend with for this garden. First was a mature black walnut that succumbed to thousand canker disease. The city required that the tree be taken down as soon as possible to stem the spread of the disease.[…]
We sheet mulched this area heavily, up to 18 inches in places, as adding organic matter is reportedly the best way to lock-up and break down allelopathic chemicals [from the black walnut]. We used cardboard from the local bike shop to smother the bluegrass lawn, cow manure from a local ranch for fertility, leaves the client had collected over the years, and cast-off strawbales. The soil is now a nicely assimilated, dark and crumbly consistency. We harvested the runoff from nearly half of the house roof surface to gravity feed through four infiltration basins as the sole irrigation source. While most landscapes in Boulder are over-irrigated with municipally treated water, this garden harvests almost 10,000 gallons of rainwater annually to passively infiltrate into the soil, requiring zero municipal water post establishment. […]
We mulched the basins heavily with woodchips from a local tree trimmer to absorb the rainwater, reduce evaporation, and to prevent creating mosquito breeding habitat. Previously the water ran down the driveway and into the street only to evaporate in summer or ice up in winter. After three months of hand irrigation for plant establishment this garden now thrives strictly on harvested rainwater. After first digging the water harvesting earthworks, then planting the trees and shrubs, and following with sheet mulch, we planted various other useful plant species for nitrogen fixation, nutrient accumulation, pest confusion, and beneficial insect attraction. Most of the species have edible or medicinal qualities as well. […]
The growth in this garden is fantastic, and even better the homeowner has become a sincere advocate for rainwater harvesting and forest gardening. It has been two years since the garden was installed and it is encouraging to see the abundant results of needing no irrigation, producing food, creating wildlife habitat, being a great place to bring students, and simply being beautiful. This garden is an awesome place to eat, observe, and be! The scale of the garden is only 750 sq. ft. and is therefore easily and affordably replicated. With extremely low maintenance and no continuous irrigation cost, this garden has attracted other city dwellers to extend the edible forest ecosystem to other yards and neighborhoods. Perhaps the greatest yield from this garden is the food forest revolution that it has inspired!

From “At O’Hare Airport, Unused Land Is Going to the Bees” by Zak Stone:
In May, the Chicago Department of Aviation partnered with a community group to start a 2,400 square foot apiary on-site. Now 23 beehives are up and running and are scheduled to yield 575 pounds of honey this year. The project offers a creative, sustainable, and productive way to use otherwise wasted open space at mega-airports like O’Hare. The bees’ new home on the east side of the airport campus had long stood vacant, so it was a natural spot for the bee program to begin. And if that’s not enough benefit, the beehives provide employment opportunities for formerly incarcerated adults (similar to other projects that teach prisoners beekeeping).
Sweet Beginnings, the offshoot of the local economic development agency that’s managing the project, trains felons in the art of beekeeping and the process of making honey, candles, and lotions, which are sold under the brand Beeline. O’Hare’s shops intend to start selling the hyper-local honey products soon. “It is the perfect example of a green business operating and growing in Chicago, while also providing opportunities to those who need a second chance,” said former Chicago mayor Richard M. Daley.

From We Are All Human Microphones Now by Richard Kim:
Anyone who’s been down to Occupy Wall Street and stayed for a General Assembly will instantly recognize the call and response that begins, and frequently interrupts, each meeting.
“Mic check?” someone implores.
“MIC CHECK!” the crowd shouts back, more or less in unison.
The thing is—there’s no microphone. New York City requires a permit for “amplified sound” in public, something that the pointedly unpermitted Occupy Wall Street lacks. This means that microphones and speakers are banned from Liberty Plaza, and the NYPD has also been interpreting the law to include battery-powered bullhorns. Violators can be sentenced for up to thirty days in prison. Further complicating the matter is the fact that Liberty Plaza is not actually a public park. It’s privately owned by Brookfield Office Properties, landlords to Bank of America and JPMorgan Chase, and in addition to amplified sound, they’ve also sought to ban sleeping bags, tents and other equipment from what they call “Zuccotti Park.”
So despite all the attention given to how Twitter, Facebook and livestream video have helped spread the word, the heart of the occupation is most definitely unplugged. But the protesters aren’t deterred one bit; they’ve adopted an ingeniously simple people-powered method of sound amplification.
After the mic check, the meeting proceeds:
with every few words?/?WITH EVERY FEW WORDS!
repeated and amplified out loud?/?REPEATED AND AMPLIFIED OUT LOUD!
by what has been dubbed?/?BY WHAT HAS BEEN DUBBED!
the human microphone?/?THE HUMAN MICROPHONE!!! (jazz hands here).
The overall effect can be hypnotic, comic or exhilarating—often all at once. As with every media technology, to some degree the medium is the message. It’s hard to be a downer over the human mic when your words are enthusiastically shouted back at you by hundreds of fellow occupiers, so speakers are usually pretty upbeat (or at least sound that way). Likewise, the human mic is not so good for getting across complex points about, say, how the Federal Reserve’s practice of quantitative easing is inadequate to address the current shortage of global aggregate demand (although Joe Stiglitz valiantly tried on Sunday), so speakers tend to express their ideas in straightforward narrative or moral language.

WaterShed, the University of Maryland’s [winner of] the U.S. Department of Energy’s Solar Decathlon 2011, is a solar-powered home comprised of systems that interact with each other and the environment. A home that harvests, recycles, and reuses water, WaterShed not only conserves but produces resources with the water it captures. Inspired by the rich, complex ecosystems of the Chesapeake Bay watershed, the home displays harmony between modernity, tradition, and simple building strategies, balancing time-trusted best practices and cutting-edge technological solutions to achieve high efficiency performance in an affordable manner. The home was built by a multi-disciplinary team of students over the course of two years.
About the Design:
WaterShed is a solar-powered home inspired and guided by the Chesapeake Bay ecosystem, interconnecting the house with its landscape, and leading its dwellers toward a more sustainable lifestyle. The house is formed by two rectangular modules capped by a split-butterfly roof that is well-suited to capturing and using sunlight and rainwater. The spacious and affordable house features:
- constructed wetlands, filtering storm water and grey water for reuse
- a green roof, retaining stormwater and minimizing the heat island effect
- an optimally sized photovoltaic array, harvesting enough energy from the sun to power WaterShed year-round
- edible landscapes, supporting community-based agriculture
- a liquid desiccant waterfall, providing high-efficiency humidity control in the form of an indoor water feature
- a solar thermal array, supplying enough energy to provide all domestic hot water, desiccant regeneration, and supplemental space heating
- engineering systems, working in harmony and each acting to increase the effectiveness of the others
- a time-tested structural system that is efficient, cost-effective, and durable.
About the Solar Decathlon:
The U.S. Department of Energy’s Solar Decathlon is a biennial competition challenging 20 student teams from universities around the world to design and build houses powered entirely by the sun. Over ten competition days, the teams compete in ten different events such as architecture, engineering, and affordability. The team with the highest overall score is the winner. Each day the winner of one of the ten contests is publicly announced, providing the opportunity for individual recognition among the decathlete teams. The winner of the 2011 competition will be the team that best blends affordability, consumer appeal, and design excellence with optimal energy production and maximum efficiency. This year’s competition [was] on public display in the solar village at West Potomac Park, Washington, DC from September 23 – October 2. The house entries will be judged in subjective contests such as market appeal, communications, and home entertainment, and objective measured tests such as comfort zone, hot water, and energy balance. The houses are on public exhibition with the intent of educating visitors about environmental issues, emerging sustainable technologies, and energy-saving measures.
