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.

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.”

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.

In general, fruit and vegetables produced in city environments contain more undesirable substances than rural produce.

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.

Before fridges and electricity existed, digging a hole in the ground was just one of the many ways people went about preserving their perishables. Despite taking its cues from this old method, the Ground Fridge still feels like a fresh idea.

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.

Urban canners and college researchers are testing city-grown fruit to see if it is safe

Last month, the Wellesley researchers announced some unexpected results of their early tests: Not only are they safe, but fruits off city trees — or sidewalks — may be more nutritious than those on store shelves.
“We’re excited about these initial results, and the biggest surprise is the micronutrients,” says Brabander. “I think there’s a growing realization that urban environments can support a wide range of agricultural activities, from food projects to community gardens to foraging.” He and his students presented their methodology and preliminary results to the Geological Society of America’s annual meeting in Baltimore.

“It is highly unlikely that urban agriculture will increase incidences of elevated blood Pb for children in urban areas. This is due to the high likelihood that agriculture will improve soils in urban areas, resulting in reduced bioavailability of soil Pb and reduced fugitive dust.”

Using compost is the single best thing you can do to protect your family from any danger associated with lead in urban soils. Good compost will also guarantee that you will have plenty of vegetables to harvest.
That’s the main finding of a paper appearing this month in the Journal of Environmental Quality. The University of Washington-led study looked at potential risks associated with growing vegetables in urban gardens and determined that the benefits of locally produced vegetables in cities outweigh any risks from gardening in contaminated soils.

Control of rodents is essential for food safety and financial success on urban farms.

It is essential for beginning farmers, home gardeners and experienced farmers to prevent rodent infestations on the farm. Rodents affect the farm in several ways. First and foremost, they are disease carriers. Rodents can cause, but not limited to Hantavirus Pulmonary Syndrome, Leptospirosis, Salmonellosis and Rat Bite Fever. Additionally they contribute to the spread of other diseases caused by the parasites that infect rodents. Rodents also cause physical damage to structures. Rat’s teeth never stop growing and to keep them from getting to long, a rat must chew to grind them off. The chewing can cause damage to wood, plastics and concrete used in the urban farming operation. Finally, rodents cause financial loss due to crop damage, and damage to facilities.

Highline College program — with new $80K grant—brings urban agriculture classes and resources to area residents
Andy Satkowski waters the edible garden at Highline College earlier this year. The garden gives students like Satkowski, who is enrolled in the college’s new Urban Agriculture certificate program, hands-on practice growing and harvesting fruits and vegetables.
Des Moines, Washington. Highline will recruit participants from the area’s immigrant and refugee communities.

The college’s 80-acre campus provides plenty of space for demonstrating and practicing urban agriculture, agroforestry and edible landscaping. Through these efforts, Highline will promote deeper understanding of and support for community-wide food security.
The total cost of Highline’s two-year project is $194,000. The college is funding the balance of the project, which it expects to become self-sustaining through tuition revenue.
