One of his accomplishments was to convince the Berkeley planners to turn over a piece of land next to a BART tunnel for the establishment of a communal garden, where it still exists—The Carl Linn Peralta Community Garden.

RW: In establishing a commons, would you say, that ideally part of what it would consist of would be a garden?
Karl Linn: Well in the past I saw an interesting development. I worked in about ten cities and established two non-profit corporations and inspired about eight others that were the first pioneering community design centers where volunteer professionals worked with economically disenfranchised neighborhoods helping them to build these common areas—architects, landscape architects, anthropologists, sociologists, lawyers, just name it. There was always some vegetation, but primarily we used recycled building materials, voluntary labor and tax delinquent land. From urban renewal demolition we used marble steps, bricks and flagstones.

In 2016 in New York City people will be able to visit a barge containing edible, perennial plants. We want to reinforce water as a commons, and work towards fresh food as a commons too.
By Adam Born
June 14, 2016
A leased barge, measuring in at 120 x 30 feet, will provide the foundation for a forest growing a range of produce. Whilst touring piers around New York state for six months, the forest will accommodate up to 300 people per day coming aboard, exploring and foraging for anything from herbs, berries and kale to kiwis.
The project is partly inspired by the growing urban agriculture movement found in New York City, now home to the largest rooftop farms in the world. From what was once a hobby for a few keen enthusiasts, this expansion has been supported by grassroots movements, volunteering and municipal programs.

Last summer was so hot that many probably thought it was one for the books. Well, it turned out that Earth in 2015 had its warmest summer in recorded history. It was another sign that the planet is heating up, due mainly to human-induced greenhouse-gas emissions into the atmosphere.
For some folks in Vancouver, the dry conditions at the time made gardening so challenging that they immediately started an experiment.

Agricultural chemicals are only part of the problem. Homeowners and urban landscapes are big contributors, even when hives are directly adjacent to crop fields.”

“Although crop pollen was only a minor part of what they collected, bees in our study were exposed to a far wider range of chemicals than we expected,” said Krupke. “The sheer numbers of pesticides we found in pollen samples were astonishing. Agricultural chemicals are only part of the problem. Homeowners and urban landscapes are big contributors, even when hives are directly adjacent to crop fields.”
Long, now an assistant professor of entomology at The Ohio State University, said she was also “surprised and concerned” by the diversity of pesticides found in pollen.

The environmental benefits of urban farming get even more complicated when we consider indoor “vertical farms,” which are often touted as a sustainable option that use less soil and water. Although designs differ, some of these set-ups can use an enormous amount of energy, especially if they require artificial lighting.

“It’s hard to make sweeping generalizations here,” Santo told me. When designed right, urban farms can make some modest but valuable improvements to the sustainability of our food system. But when designed poorly, they can end up being even worse for the environment — say, if they’re using fertilizer inefficiently and polluting nearby waters with nitrogen run-off.
In our conversation, Santo mentioned one feature of urban farms that often gets shortchanged in dry policy discussions: “They can reconnect people with how to grow food.”

“I think a mother killdeer could not have chosen a better place for a nest,” said Clavette.

May 07, 2016
Community gardeners near the Moncton Area Control Centre were expecting to dig in for another planting season but instead found a killdeer had set up a nest right in the middle of their plot.
Charles Daigle, a photographer who works for NAV Canada in Riverview, found the bird when he went to till the garden. He has since done his best to make sure it would be protected.
“We’re going to be delayed a bit of course. I’m in charge of the garden but I talked to the people who are in charge of the building and basically we all made the decision unanimously to give the bird some space and let it do its thing.”

Current Opinion in Environmental Sustainability
This paper systematically reviews literature on urban and peri-urban agriculture and forestry (UPAF) in mediating climate change. The study includes both peer-reviewed and grey literature (274 literature sources), and synthesizes evidence and agreement on both UPAF’s potential and limitations for mitigating and adapting to climate change. Eight East and West African cities were included in the review: Accra, Addis Ababa, Dakar, Dar es Salaam, Douala, Kampala, Ibadan and Nairobi. The review focuses on urban livelihoods, ecosystem services and urban policy responses as pathways to mediating climate change.

The Nature of Cities
April 8, 2016
Get back to the ground level: conventional farming within cities is potentially a much graver concern, be it located in a skyscraper or just in the ground. The big issue here is the dissemination of pesticides and fertilizers as well as of the wastes and the by-products of industrial urban agriculture, especially in vine-growing or grain-growing regions—two agricultural productions with high added-value—where vines and fields are frequently incorporated in the city. The inhabitants of such cities are exposed to critical levels of pesticides on a daily basis without them even knowing. Well, they are beginning to know, and it appears that they are not happy at all.

The earthquake, tsunami, and resulting nuclear disaster that rocked Japan’s Tohoku region in March of 2011 dealt a series of sharp blows to the 70,000 farmers living in Fukushima prefecture

City Farm Odaiba, which sits atop a high-rise overlooking Tokyo Bay, on the manmade island of Odaiba, represents one of many initiatives aimed at reversing the farm-sector decline. Established in 2012 by real-estate behemoth Mitsui Fudosan as a kind of refuge for elderly farmers who had fled Tohoku after the tsunami, the community farm—with rice paddies, soybean fields, staked tomatoes, raised beds, and a flock of resident chickens—quickly became something more than a place for the displaced people to dirty their trowels.

It may be possible to build new cities that avoid the current contamination issues. But in existing cities, where urban farming is an afterthought, some lateral thinking is required to give urban agriculture a future. Growing non-food crops such as textile fibre plants, biomass crops and timber would make use of urban and suburban waste land, green the city, recycle waste water and biosolids, and produce crops that currently take up rural land that is ideal for food production.

Food safety authorities recently warned that Dar es Salaam residents who eat vegetables grown in the urban gardens may be exposed to health risks caused by the waste matter and industrial spills contaminating the farms’ water supply.

Shoppers buying fresh vegetables from the maze of stalls at Dar es Salaam’s Kariakoo market have no idea of the risks they are taking, but food safety officials are alarmed by the chemicals and effluent in the water used on the city’s urban farms.
Doreen Nkya always buys some spinach or amaranth on her way home because she considers them an important part of her family’s diet. “I like vegetables because they are healthy. We don’t often go without them at our dinner table,” she said.

In heavily-polluted cities like Beijing and Shanghai, people are paying upwards of $160 for a single jar of air

Leo De Watts from Britain has jumped on the bandwagon; selling jars of air collected from locations like Yorkshire, Somerset and Wales.
The air from each region is described in elaborate detail that may be surprising for those who do not consider themselves “air connoisseurs”.
Welsh air for example has a “morning dew feel to it” with “vibrant and flavoursome undertones” whilst air originating from Somerset has “unblemished qualities”.

Kopf went to Lightfoot, and told him that she was leaving to start a greenhouse software company — or, as she put it, “Hey. I’m going to do this. Buy it.” She found a programmer and cofounder, a Google engineer named Jason Camp, through a family friend. Agrilyst launched in spring of 2015. By autumn of 2015, the duo had beat out 1,000 other companies and were standing onstage as one of 25 finalists at the TechCrunch Disrupt startup competition in San Francisco. Much to their surprise, they won.
