(Must see. Mike)
With Stark and Carlson, everything was different. We parked our car at a corner in West Oakland and within seconds these gents were pointing out sow thistle, mallow, dock, sourgrass, and nearly everything else you see here. Most of it was good enough to eat on the spot; some of it would’ve benefited from cooking. A portion … well, I’d ignore.

Feature documentary looking at the latest science about the health benefits of children re-connecting with nature
“I think that city farms could play a massive part in future health!”
By Toni Harman,
Producer / Director, A Probiotic Life
As well as the general point about the need for our children to reconnect with nature, the film explores the latest science that suggests young children could really benefit from being more exposed to more farm microbes.
We recently returned from filming on an Amish farm in Indiana where the children have remarkably low rates of asthma and allergies – the scientists hypothesise that a diet of locally sourced organic food plus the children being exposed to the microbes from farm animals from a very young age – these could be conferring considerable health benefits for the Amish children.

From flower-emblazoned cemeteries to rooftop gardens and balconies, Norway’s capital Oslo is creating a “bee highway” to protect endangered pollinators essential to food production.
“We are constantly reshaping our environment to meet our needs, forgetting that other species also live in it,” Agnes Lyche Melvaer, head of the Bybi, an environmental group supporting urban bees, which is leading the project.
“To correct that we need to return places to them to live and feed,” she explained, sitting on a bench in a lush city centre square bursting with early Nordic summer growth.

Agriculture is highly dependent on local weather conditions and, therefore, is expected to be highly sensitive to changes in climate in the years to come.
FAO Press Release

8 June 2015, Rome – Global warming will have profound consequences on where and how food is produced, and also lead to a reduction in the nutritional properties of some crops, all of which has policy implications for the fight against hunger and poverty and for the global food trade, experts say in a new book.
“Climate Change and Food Systems” collects the findings of a group of scientists and economists who have taken stock of climate change impacts on food and agriculture at global and regional levels over the past two decades.
“The growing threat of climate change to the global food supply, and the challenges it poses for food security and nutrition, requires urgent concerted policy responses … ,” wrote FAO Deputy Director-General Natural Resources, Maria Helena Semedo, in her foreword to the volume.

Blair Leano-Helvey is bringing a new twist to Louisville’s growing urban agriculture scene. She’s started a butterfly farm.
“It’s just like any other farm,” she said. “It’s just that we have very small livestock.”
And colorful, too.

Although the vineyard is only three-fourths of an acre, Frazier did his homework on what to plant, where, and how. Frazier was a complete novice, so he immersed himself in learning.
He’s consulted with Greg Johns, manager of Ohio State University’s Ashtabula Agricultural Research Station, and David Popp of Bacchus Vineyard & Winery Services LLC, who serves as his viticulturist.
There are 14 rows, 21 vines per row, half Frontenac and half Traminette, chosen specifically for their cold-hardiness.

The lack of an effective system of trash sorting and processing works against us, because much of the waste used for compost in the urban organic gardens has had previous contact with materials like cans, paints, and batteries, thrown indiscriminately into landfills all over the country.

Nationwide, about 40,000 people work in urban agriculture projects on some 83,000 acres (130 square miles) that are divided into 145,000 parcels, 385,000 patios*, 6,400 intensive gardens and 4,000 urban organic gardens. These last under the leadership of the Ministry of Agriculture, although with some autonomy for crop management.
With these lands planted in populated areas, it has been the goal to reduce food insecurity, offer greater access to fresh produce and to expand green spaces in urban zones.

Other pollinators don’t like urban areas as much as rural, but bees live in similar numbers across different landscapes
By Marissa Fessenden
February 12, 2015
Katherine Baldock, of the University of Bristol, surveyed pollinator abundance across 36 different sites that spanned farmland, nature reserves and urban areas. Her team counted honey bees, bumble bees and other flying pollinators. The group found that each area had about the same amount of total pollinators. Even though urban areas might not seem like the ideal place for flower-loving bees, those landscapes held more diverse bee species, though the other pollinators were less diverse and numerous. Baldock and her colleagues published their findings in the Proceedings of the Royal Society B.

Designing for Beauty and Biodiversity in the Home Garden
By Rick Darke and Doug Tallamy
A home garden is often seen as separate from the natural world surrounding it. In truth, it is actually just one part of a larger landscape made up of many living layers. And the replacement of the rich layers of native flora with turf grass greatly diminishes a garden’s biological diversity and ecological function.

Stella Ursua works for a greener Long Beach
By Andrew Edwards
For Stella Ursua, an acre or so’s worth of carrots, kale, strawberries, tomatoes and other produce growing in the middle of the city is but an example of her vision for a greener city.
The crops grow at a place called Lincoln Spring Farms, near the crossing of Spring Street and Atlantic Avenue within site of Long Beach Memorial Medical Center. The catchphrase for such a place is “urban farming,” and Ursua herself doesn’t run the farm, she said. It’s an example of the kinds of activity her organization, Green Education Inc., seeks to promote.

WASHINGTON (AP) – In May 2013, the mayor of the nation’s capital announced that the city would partner with a produce supplier to build what the company called “the most productive urban farm in the world.”
But no one bothered to inspect the site. If they had, they would have found an unlicensed landfill that’s 18 feet deep; 10-foot-high piles of debris including roofing material and insulation; and rusting petroleum containers on the banks of a creek.

Vigil told me that the farms have soil tested every year for lead levels, and the results have always come out safe. So when the press started railing against the toxic dangers of his veggies, Vigil was put off (OK, he was royally ticked). He wrote an open letter about what’s really going on and how urban farmers are handling soil toxins. Here’s a taste:
In the past two years we have partnered with the Department of Sanitation to distribute over 5,000 bags of NYC Compost to East New York gardens, and applied over 10 cubic yards of new compost to our farm.

Paired vegetable/soil samples from New York City and Buffalo, NY, gardens were analyzed for lead (Pb), cadmium (Cd) and barium (Ba). Vegetable aluminum (Al) was measured to assess soil adherence. Soil and vegetable metal concentrations did not correlate; vegetable concentrations varied by crop type. Pb was below health-based guidance values (EU standards) in virtually all fruits.

Heather Hava, right, who is working on a doctorate in aerospace engineering sciences at the University of Colorado Boulder, describes a computerized system she is developing with other graduate students participating in the exploration HABitat (X-Hab) Academic Innovation Challenge.
The ROGR robots can visit a specific plant to deliver water or to locate and grasp a fruit or vegetable. If an astronaut requests tomatoes for a salad, the system decides which specific plants have the ripest tomatoes and assigns parallel harvesting tasks to ROGR.

For more than a half-century, NASA has made the stuff of science fiction into reality. Researchers are continuing that tradition by designing robots to work in a deep-space habitat, tending gardens and growing food for astronaut explorers. It sounds like a concept from Star Wars, but a team of graduate students from the University of Colorado Boulder is now developing the innovative technology to make it possible.
As astronauts explore beyond Earth, they will need to make their habitat as self-sustaining as possible. This includes growing fruits and vegetables.

Understanding the role of urban and peri-urban crop production in urban food security at scale remains a major knowledge gap in the field of urban agriculture.

Published 3 November 2014
The role of urban agriculture in global food security is a topic of increasing discussion. Existing research on urban and peri-urban agriculture consists largely of case studies that frequently use disparate definitions of urban and peri-urban agriculture depending on the local context and study objectives. This lack of consistency makes quantification of the extent of this practice at the global scale difficult. This study instead integrates global data on croplands and urban extents using spatial overlay analysis to estimate the global area of urban and peri-urban irrigated and rainfed croplands.
