A field-trial study conducted in the United States, where small-scale urban agriculture has become more prevalent due to the availability of abandoned property and demand for locally grown produce. Weed suppression is described as a major concern for urban growers, with mulch valued as an inexpensive, readily available control method. Black plastic mulch, the industry standard, is impermeable and difficult to remove and dispose of; newspaper end-rolls (unprinted remains from newspaper printing) are proposed as an alternative that is permeable and biodegradable but have a high C:N ratio that can reduce soil fertility and crop growth. Because plant residue alone requires large quantities for adequate weed suppression, combining newspaper with plant residues is proposed as a way to achieve adequate suppression with less material and a lower C:N ratio. The study's objective was to compare two continuous sheet mulches — newspaper and black plastic — with and without an underlying particulate mulch of killed cover crop, in field trials conducted in 2011 and 2012 measuring soil moisture, soil temperature, weed growth, weed removal cost, and collard (Brassica oleracea) performance in a low-input production system. The abstract does not report specific results.

Sandy Campbell · The Deakin Review of Children s Literature · Canada

This is a review of Hadley Dyer's "Potatoes on Rooftops: Farming in the City" (Annick Press, Toronto, 2012). Although marketed by the publisher for grades 4–7, the reviewer finds the actual reading level higher — Tenth Grade on the Coleman-Liau Index and 9.2 on the Flesch-Kincaid Grade Level test. Despite a children's-book design, the content is dense and textbook-like, moving from an introduction on food and the need for urban agriculture through small- and larger-scale urban agriculture examples to related social and political movements, with a glossary, resource list, and index. The Toronto-based author received Ontario Arts Council funding, but the review notes little Canadian content, with the book's apparent market being the United States; it cites international examples including Africa, Japan, and Scotland but says little about the practicalities of urban gardening in Canada, where growing conditions differ sharply by region (e.g., Florida vs. Edmonton). The review rates the book 3 out of 4 stars, recommending it for high school and public libraries and noting it is most useful for teen and adult readers.

Michael Dubnewick, Karen M. Fox, D. Jean Clandinin · Leisure/Loisir · Canada

This autobiographical narrative inquiry follows one author's (Michael's) lived experience of gardening with his family's gardens and two community gardens, Heritage and Eco, in Edmonton, Canada. Using narrative inquiry methodology, the authors present institutional, community and personal narratives from Michael's gardening experience to illustrate gardening as a leisure practice shaped by multiple, sometimes paradoxical, contexts of people, cultures and communities.

In Worcester, Massachusetts, an urban farmers' group called "The Shop" built a greenhouse for year-round produce, but it became too cold to sustain plant growth during winter. Drawing on the group's composting experience, a project examined using biogas -- methane from anaerobic digestion of organic waste -- to heat the greenhouse, calculating the energy needed to heat the space and the expected energy yield from different available substrates using data from case studies and other sources. The results verified biogas as a viable way to heat the greenhouse at The Shop.

This paper examines guerrilla gardening as an example of sustainability in action, using participatory action research methods. Two case studies were developed in Kingston, Ontario: Dig Kingston, a guerrilla gardening project, and the Oak Street Community Garden. The research found that interventions like guerrilla gardening open up unexpected possibilities for conceptualizing sustainability and contribute to producing engaging and sustainable communities.

Mary Margaret Fischer · OpenSIUC (Southern Illinois University Carbondale) · United States

This study evaluated commercial and vermicompost-blended green roof media for annual herb production in shallow modular trays on a university roof in Southern Illinois, Carbondale, during two experiments in 2011. The commercially available media generally produced more significant results for shoot growth parameters in sweet basil, Thai basil, and parsley. Partial shade also showed significant effects on shoot-to-root ratio in the first experiment, while most basil variables were insignificant in the second.

This report assesses irrigation systems for a new rooftop garden at the Student Union Building (SUB) in Vancouver, Canada, which aims for LEED Platinum+ certification. Micro-irrigation is recommended due to limited space, the need for high water efficiency, and a low carbon footprint. Micro-irrigation systems apply water directly to plants, reducing evaporation and energy costs, with an observed 80% improvement in water efficiency compared to conventional practices.

Community Gardening Works! ACGA 2011 Conference, Mara Gittleman, Kelli Jordan, Eric Brelsford · Cities and the Environment · United States (New York City)

This paper is a case study of Farming Concrete, a community-based project in New York City, which has more than 500 community gardens, over 80% of which host food production according to a 2010 GrowNYC survey. Using citizen science methods in which gardeners and researchers jointly designed and conducted the research, the project measured how much food was grown in New York City community gardens in 2010 and 2011.

Mikhaela Mullins · Lincoln (University of Nebraska) · United States (Lincoln)

This case study at Saratoga Elementary School in Lincoln, Nebraska, aimed to identify children's desires for a garden space. A school garden was constructed, and an after-school garden club was implemented, where participating students drew their ideal gardens. Elements from these drawings were categorized as 'highly desired' or 'somewhat desired' and subsequently integrated into a proposed garden design plan for Saratoga, which utilizes Permaculture design methods for sustainability.

Renato Teixeira de Oliveira · Cadernos de Agroecologia · Brazil (Fortaleza)

This experiment, conducted at the Urban Agriculture Teaching and Research Center of the Federal University of Ceará in Fortaleza, Brazil, evaluated the influence of different container sizes and substrates on andiroba seedling development. Seedlings grown in 24.6 L polyethylene bags showed statistically superior aerial part height, collar diameter, main root length, and dry mass of aerial part and root system compared to those produced in smaller bags after 190 days. Dry masses of the aerial part and roots were also greater for seedlings developed in the substrate containing earthworm humus.

Louise Chawla · Children Youth and Environments · United States (New York City)

This article reviews the 2010 film "Truck Farm," directed by Ian Cheney, which explores urban gardening in New York City. The film follows Cheney as he cultivates a vegetable garden in his grandfather's pickup truck and visits other urban farmers and food experts across the city. "Truck Farm" combines serious exposition with humor, prompting viewers to consider the future of urban farming and the role of whimsy in sustainability. The reviewer suggests the film is a valuable resource for youth community gardening programs or food systems classes.
