As Melco explains in the video, the main goal of the project is to protect residents, especially babies and young children— from chronic, low-level exposure to potentially harmful chemicals. Through a partnership with Portland Metro, The Xerces Society, and Backyard Habitat Certification Program, Melco and her team are going door to door canvasing the 2500 homes to educate homeowners.

Worthy, indeed, is the garden that is planted, not for beauty alone, but for the welfare of Nature’s children as well.
By the Bird Man.
A host of fruit-loving birds lived in the garden in early summer. They feasted continuously on choke and wild cherries, and cloyingly sweet mulberries. Seldom at any other season, did the shy, elusive cedar wax-wings enter the garden, but love of the purple fruit of the mulberry dispelled all fear in June. The bluebirds and orioles were equally fond of it, but they must, perchance, satisfy their appetites with that which fell to the ground, for the wax-wings claimed the trees.

Gov. Jerry Brown, meanwhile, has asked residents across the state to cut water use by 20%, a goal that has proved slippery so far. In some areas of the state, landscaping accounts for half of daily water use …

The new mascot will be popping up on billboards donated by Clear Channel Outdoor across the parched region, spouting catchphrases like “Don’t hose me man!” as reminders to refrain from overwatering lawns. On another billboard, Lawn Dude carries a martini glass holding a daisy and says, “I only drink 2 days a week”—a nod to limits on outdoor irrigation to twice a week in some communities.

When it comes to remediation, there are a few ways to deal with the problem. One is cap-and-fill (covering over an existing lot with cement, then trucking in soil and building a garden overtop), which is preferred by many municipal governments, simply because it buries the problem, says Wortman. There is also phytoremediation, in which plants slightly better at absorbing lead, like mustards and sunflowers, are planted on vacant land, then harvested and disposed of over a long period of time. While this technique is trendy right now, probably because it feels like “using nature to heal nature,” Wortman says it isn’t practical or effective.

From the bestselling author of Crow Planet, a compelling journey into the secret lives of the wild animals at our back door.

In The Urban Bestiary, acclaimed nature writer Lyanda Lynn Haupt journeys into the heart of the everyday wild, where coyotes, raccoons, chickens, hawks, and humans live in closer proximity than ever before. Haupt’s observations bring compelling new questions to light: Whose “home” is this? Where does the wild end and the city begin? And what difference does it make to us as humans living our everyday lives?

Artists Probe Urban Agriculture
By Allison Meier
July 1, 2014
In collaboration with Smack Mellon’s FOODshed, Alloy real estate development, and Brooklyn Grange, artist Andrea Reynosa planted a 6,000-square-foot field with clover that is sprouting red flowers alongside the Manhattan Bridge. The space was formerly a parking lot. The flourish of vibrancy is temporary, but Reynosa is planning that through the clover, a site that might otherwise be an empty construction lot will have life that will in turn ameliorate the soil before a condominium moves in.

The University of Minnesota is studying whether urban farming can reduce heat in metropolitan areas.
“If you’re farming in a city, then you’re taking what used to be an impervious surface with little vegetation and making it pervious and growing vegetation”
By Lyra Fontaine

This summer, new University research will explore a new way of mitigating heat islands — urban farming — which could help reduce heat in metropolitan areas while providing a source of fresh produce and groceries to cities.
This has yet to be explored, said Katherine Klink, a geography, environment and society associate professor.
“People just haven’t thought of [urban farms] as a potential heat island mitigation strategy,” Klink said.

How urban agriculture set-ups cultivate local produce with the help of innovative water recirculation systems.
By Saul Chernos
May 12, 2014
“We’re trying to reduce our footprint on the environment as much as we possibly can,” explains Lauren Rathmell, a founding member who oversees Lufa’s greenhouse operations. She says Lufa’s hydroponic greenhouses use up to 90 per cent less water than comparable ones that don’t recirculate. “It’s all automated. We irrigate most of our plants using drip lines set up where we water the plants from above. Water that’s not taken up by the plants and doesn’t evaporate is captured, sent down to our collection tank, filtered, and reused.” Some plants, mostly the lettuces, grow with their roots submerged entirely in gently flowing water, continuously irrigated. Others sit in soilless coconut husk grow sacs.

While growing food within city limits is exciting for urban dwellers, it also raises some unique food safety issues.

To be clear, my opinion is that urban farmers and gardeners can absolutely keep livestock safely within the city limits. However, my experience has been that urban livestock keepers are also more likely to be novices. As a result, I have seen some unfortunate situations where people underestimate the amount of attention baby goats need or the dedication it takes to milk a goat every day.

Pallet manufacturers in Canada and the United States must now either heat-treat or fumigate pallets as a precaution against such pests as the emerald ash borer.
Discarded shipping pallets, long used as construction material by gardeners, have now been discovered by crafters. But recent regulations designed to prevent invasive pests from hitching a ride in the wood mean some pallets really shouldn’t be used in the garden or home (or burned for fuel, either).

In New York City, there are more than 700 community gardens and urban farms.
By Vinnie Mancuso
New York Observer
Bad news for people who like to support their local community gardens when shopping for their vegetables. Good news for people who love ingesting arsenic and lead with their vegetables.
The New York Post reports that a study on soil contamination by the state Center for Environmental Health found toxic soil at 70 percent of New York’s gardens. A shocking 44 percent of the total gardens had lead levels above federal guidelines.
A Freedom of Information Law request by the Post revealed the exact names and locations those gardens most contaminated. Brooklyn did not come out looking so hot.

RUAF Urban Agriculture Magazine No. 27, March 2014
RUAF-Foundation (International network of Resource centres on Urban Agriculture and Food security)
This issue is prepared with support of the UN Habitat Cities and Climate Change Initiative. It reports on the joint urban agriculture programme implemented by RUAF and UN Habitat. This issue also shares findings of a CDKN funded innovation project on monitoring urban agriculture impacts on climate change.
Cities and climate change are virtually inseparable. Cities are major contributors to Green House Gas (GHG) emissions and thus climate change.

“Rooftop farms in some of the world’s most crowded cities, including Hong Kong, New York and Tokyo, are adding green to the gray. They are reconnecting city dwellers with nature, teaching consumers about homegrown food and offering a glimpse, perhaps, of a more secure and sustainable food supply.”
—Mary Hui, New York Times (2012)
Many commentors now predict that we will see peak food around the world in the next two decades— we will begin to consume more food than we can possibly produce. Following that, alternatives to the current model of mass agriculture will have to be found. A big potential for an alternative model lies within the idea of the natural city.

The people need their guacamole. Or so it seemed when the Internet exploded in rage and disbelief this week over a line in an otherwise mundane risk assessment sent to investors in Chipotle, the popular Mexican fast food chain. It concluded that climate change is affecting the price of some ingredients, like avocados and tomatoes, and Chipotle could be forced to cut out guacamole, at least temporarily.
