17pgs, There is a lack of data on resources used and food produced at urban farms. This hampers attempts to quantify the environmental impacts of urban agriculture or craft policies for sustainable food production in cities. To address this gap, we used a citizen science approach to collect data from 72 urban agriculture sites, representing three types of spaces (urban farms, collective gardens, individual gardens), in five countries (France, Germany, Poland, United Kingdom, and United States). We answered three key questions about urban agriculture with this unprecedented dataset: (1) What are its land, water, nutrient, and energy demands? (2) How productive is it relative to conventional agriculture and across types of farms? and (3) What are its contributions to local biodiversity? We found that participant farms used dozens of inputs, most of which were organic (e.g., manure for fertilizers). Farms required on average 71.6 L of irrigation water, 5.5 L of compost, and 0.53 m2 of land per kilogram of harvested food. Irrigation was lower in individual gardens and higher in sites using drip irrigation. While extremely variable, yields at well-managed urban farms can exceed those of conventional counterparts. Although farm type did not predict yield, our cluster analysis demonstrated that individually managed leisure gardens had lower yields than other farms and gardens. Farms in our sample contributed significantly to local biodiversity, with an average of 20 different crops per farm not including ornamental plants. Aside from clarifying important trends in resource use at urban farms using a robust and open dataset, this study also raises numerous questions about how crop selection and growing practices influence the environmental impacts of growing food in cities. We conclude with a research agenda to tackle these and other pressing questions on resource use at urban farms.
14 pages, Since the start of the COVID-19 pandemic in March 2020, the U.S. and other countries around the world saw a dramatic increase in the number of people starting pandemic gardens. In this article, the authors use rhetorical framing analysis to explore how news coverage of this gardening boom presented the illusion of control framed around the themes of economics, food sovereignty, physical and mental health, and community and connection. It concludes with a discussion of how these four themes offer an overly-optimistic view of gardening that deemphasizes sustainability, focuses on processes over harvests, and ignores food chain inequities.
10 pages, Ongoing climate change and associated food security concerns are pressing issues globally, and are of particular concern in the far north where warming is accelerated and markets are remote. The objective of this research was to model current and projected climate conditions pertinent to gardeners and farmers in Alaska. Research commenced with information-sharing between local agriculturalists and climate modelers to determine primary questions, available data, and effective strategies. Four variables were selected: summer season length, growing degree days, temperature of the coldest winter day, and plant hardiness zone. In addition, peonies were selected as a case study. Each variable was modeled using regional projected climate data downscaled using the delta method, followed by extraction of key variables (e.g., mean coldest winter day for a given decade). An online interface was developed to allow diverse users to access, manipulate, view, download, and understand the data. Interpretive text and a summary of the case study explained all of the methods and outcomes. The results showed marked projected increases in summer season length and growing degree days coupled with seasonal shifts and warmer winter temperatures, suggesting that agriculture in Alaska is undergoing and will continue to undergo profound change. This presents opportunities and challenges for farmers and gardeners.
10 pages, BACKGROUND
Our objective was to evaluate the effect of garden-based learning on outlook and behaviors toward vegetables among primarily Latinx students. An educational strategy, garden-based learning is a teaching tool that complements other disciplines.
METHODS
Third- and fourth-grade students at 4 elementary schools with different garden programs completed a bingo survey and participated in class discussions to measure outlook and behaviors toward vegetables.
RESULTS
Students in schools with more garden exposure were more likely to answer “Yes” to survey questions reflecting a positive attitude and behaviors toward vegetables. In class discussions, students most often mentioned vegetables grown in the school garden as their favorite vegetables.
CONCLUSION
For third- and fourth-grade students, the length of exposure to a school garden appears to have a positive impact on both perceptions of and desire to consume vegetables. Other studies have shown that positive outlook and behaviors toward vegetables can change vegetable consumption habits in children. Integrating garden-based learning into the school curriculum may positively influence eating behaviors over the long-term future.
5 pages., Article # 1IAW6, vial online journal, Project Happy Apples began as an effort to assist backyard growers in managing codling moth in their fruit trees. We developed a process using emails and a web page to provide timely information related to the life cycle of codling moth and relevant integrated pest management (IPM) strategies. The content of our updates included pertinent photos, costs of tools, and suggested dates of action. Results from a survey of participants suggest that they were more confident, knowledgeable, and successful in using IPM strategies in their own backyards as a result of our project.
13 pages., via online journal., This paper conducts a detailed analysis of urban food and online networks in Bristol, UK. In particular, it examines social media postings of grass-roots food networks. Qualitative research identifies and analyses five core themes, from which two dominant discourses emerge. Analysis reinforces the multifunctional nature of city food but moves beyond dominant scholarly pre-occupations with nutrition and physical resources. Instead, the paper positions social and symbolic aspects as equal components within the convening power of food. To date, social media has been neglected in urban food research, although this is a space as well-tended and structured as the physical spaces it augments. The paper finds a relationship of limited collaboration between the grass-roots networks and the city council. While the former are dynamic and networked, the council adheres to a linear policy process that limits the scope of citizenship. The relationships examined here indicate implications for urban planning processes.
