This article suggests that establishing a Community Supported Agriculture (CSA) or farm share pickup at libraries supports the local foods movement, reduces food travel distance, promotes healthy eating, and fosters community engagement. Additional benefits include donating fresh produce to food pantries. A CSA involves a relationship where members provide labor or monetary support in exchange for a share of farm produce.

This paper presented several circular economy practices integrating circular strategies at an urban scale, focusing on the Centocelle district in Rome, Italy. Through the employment of smart solutions and a collaborative process involving citizens, circular economy urban practices such as community gardens, co-workings, local and km0 production systems, and recycling centers were identified. These practices achieved urban transformation in terms of regeneration, sharing economy experiences, resource optimization, and closed-loop systems, positively and actively influencing the urban community in supporting the transition towards circular economy models.

A study analyzed the distribution of local products through short food supply chains (SFSCs) in Hungary, focusing on farmer markets and Community Supported Agriculture systems, using data from multiple databases. Both traditional and neo-traditional SFSC forms were found to be viable in Hungary, but as in other Central and Eastern European countries, traditional SFSC types—particularly local farmer markets—remain dominant in numbers; the study concludes that forming and supporting neo-traditional organizations is useful for exploiting the potential of short supply chains.

Paul de Graaf · Eetbaar Rotterdam · Netherlands

This Eetbaar Rotterdam retrospective (author Paul de Graaf, published 30 April 2019) on Rotterdam urban farming project Uit Je Eigen Stad (UJES) states that UJES was declared bankrupt on 13 November 2018, bringing a definitive end after 6 years to one of the most notable urban agriculture experiments in Rotterdam. It opened with a festive celebration in September 2012, but the idea's seed dates to 2006, when Bas de Groot's graduation plan at the Warmonderhof school (for a care garden) went unrealized and later grew within the urban-agriculture expertise group Eetbaar Rotterdam. The site was the Marconistrip, designated a 'freezone' by the municipality; financing came from housing corporation Havensteder (investing in buildings, expecting return via rent), high-interest loans from Stichting DOEN and Rabobank, small crowdfunded contributions, and municipal officials' time (under alderwoman Van Huffelen) securing permits. The plan was to build a farm and recoup investments over 10 years, but the article describes this as a difficult effort in which urban-farming ideals clashed with profit-driven activity.

This study examined the relationship between direct marketing strategies and technical efficiency among U.S. farmers using stochastic frontier analysis. On average, farmers employing direct marketing strategies were found to be less technically efficient than those who do not. However, for the largest quantile of growers, direct marketing users were more technically efficient.

Agni Kalfagianni, Sophia Skordili · · Global

This book explores the potential of short food supply chains (SFSCs) to address environmental, social, and economic challenges in the global agri-food system. It demonstrates that SFSCs, including farmers' markets and community-supported agriculture, offer innovative forms of collective action for local sustainable transformations. The book concludes that alternatives to the dominant agri-food system are possible and thriving, but require concerted effort and collaboration to realize their full potential.

Using data from the literature and government sources, this study quantified life-cycle greenhouse gas (GHG) emissions of the United States food system at an estimated 3,800 kg CO2e per capita in 2010, with cities directly influencing about two-thirds of food-sector emissions. Assessing selected mitigation measures, the study found that up-scaling urban agriculture and expanding home grocery delivery would each cut only about 0.4% and roughly 1% of total food-sector emissions respectively, whereas changes in waste management and a 50% reduction in post-distribution food waste would cut total food-sector emissions by 5% and 11% respectively.

This descriptive piece from Utah, United States, explains Community Supported Agriculture as a farming arrangement providing a direct link between the community and the grower, in which shareholders purchase a share of the CSA and receive produce at regular intervals, typically weekly. It lists potential benefits — access to local, fresh produce free of preservatives and added hormones, and support for diversified agriculture — alongside potential barriers, including the seasonality of production, a smaller variety of products and the upfront cost of a share.

Fábio Cunha Coelho, Enilce Maria Coelho, Monika Egerer · Scientia Agricola · Global

A review paper on the consumption of locally produced food examines its relationship to local and global sustainability, the effect of transport distance ("food miles"), low-carbon farming practices, urban agriculture's contribution to local food, and links to nutrition and health. It states that transportation is not the sole determinant of how efficiently local food is consumed — the agricultural technologies used are often more responsible for the degree of sustainability — and that local production does not always mean lower greenhouse gas emissions.

RESET · RESET · France

Article from the German web media outlet RESET describing La Caverne, an underground farming project by startup Cycloponics in a disused 3,500 m² Paris car park. It grows mushrooms, endives, and microgreens, with yields ranging from 2 kg for herbs up to 300 kg for endives depending on the crop. The project uses energy-efficient LED-lit hydroponics, won the City of Paris's 'Parisculteurs' competition, and plans deliveries by electric bike and fully electric vehicles.

Malin Gustafsson, Matilda Olsson · · Netherlands (Schiedam)

This thesis focuses on a design proposal for a multifunctional foodscape in a peri-urban area on the city edge of Schiedam, in the Metropolitan Region of Rotterdam-The Hague, Netherlands. The proposal includes food production, education, and recreation, aiming to transform peri-urban areas into multifunctional zones and exemplify their role as transition zones between urban and rural landscapes. An empirical pre-study was conducted, focusing on urban farming in Rotterdam, dairy farming in Midden-Delfland, and greenhouse horticulture in Westland.

Gundula Proksch · · Global

This chapter investigates factors for implementing sustainable, energy-efficient urban agricultural operations, focusing on the solar needs of plants, the extension of growing seasons indoors, and passive solar gains for buildings. It provides an overview of greenhouse typologies, cover materials, and lighting systems to optimize energy use and production. Additionally, it examines the potential for photosynthesis and the carbon cycle to utilize building exhaust systems for CO2-rich air and excess heat to support crop cultivation, exploring intersections among nutrient, water, and energy cycles through case studies.

Youjin Jang, 곽혜란 · 한국실과교육학회지 · South Korea

This study analyzed the agricultural content of the 2015 revised elementary practical arts curriculum in South Korea, comparing it with the 2009 curriculum, focusing on goals, content systems, achievement standards, and learning elements in the agriculture and life science domain. It found that while learning elements in the agricultural domain did not significantly change, the 2015 curriculum emphasized sustainable agriculture, particularly eco-friendly future agriculture and agricultural experiences in daily life, centered on the core concept of sustainability. The study suggests that future agricultural education should incorporate multi-dimensional sustainable agriculture, such as urban agriculture, local food, and eco-friendly agricultural certification, into new textbooks.

An exploratory study of existing literature on locally grown food systems identified common findings, recommendations, and proposed priorities, key variables, and relationships for future research. Findings indicate that local food marketing through farmers' markets and Community Supported Agriculture, along with the benefits of local food systems to local economies (an ongoing debate), heavily dominate the literature. Prior studies commonly reported enthusiasm for locally grown fresh produce but presented diverging results regarding significant consumer characteristics.

Richard Almenius · · United Kingdom

A 2016 urban planning thesis on London, United Kingdom. It states that London imports 80 percent of its food, much of it from abroad over long distances ("food miles"), raising sustainability concerns and contributing to road freight congestion and pollution in the inner city. The thesis proposes redeveloping the brownfield land of Greenwich Peninsula in south-east London — near the Millennium Dome, the Thames, and underground access — by combining rooftop and courtyard urban farming with large-scale food production in a converted former industrial building, presented as a pilot project for a sustainable way of living in London beyond meeting housing needs alone.

A University of Nebraska study examined whether urban farming could support future food security through a literature review and hands-on work on small farms. Mapping community garden locations in Omaha, Nebraska against the city's median household income found that urban farming is prevalent even in poverty-affected areas, despite Omaha being surrounded by extensive rural farmland.

Hiran Roy, C. Michael Hall, Paul W. Ballantine · · Global

This excerpt is the introduction to a chapter on barriers facing hospitality businesses' use of local food; it covers only the background on rising North American and European consumer demand for local food, driven by desire for fresh food access, support for local farmers and communities, and concerns over trust, locality, transparency, animal welfare and food safety, alongside the post-1990s growth of farmers' markets, food box programs and community-supported agriculture. The specific economic barriers and constraints named in the chapter's title are not described within this excerpted text.

Jean-Francois Paquay, Sue Spaid · The Journal of Somaesthetics · Global

This philosophical essay observes that somaesthetics — the philosophy of embodied aesthetic experience — has tended to shift its focus from producers to consumers when discussing food, neglecting farmers, and proposes urban farming as a somaesthetics case study. It begins by examining urban farming's absence from Aesthetics, then discusses how the aesthetic experiences associated with urban farming collapse artistic and aesthetic distinctions, debates whether somaesthetics can be considered a subset of everyday aesthetic practice, and analyzes whether urban farming's capacity to contribute to well-being makes it a potential somaesthetic enterprise. One explanation offered for urban farming's absence from somaesthetics is that its success owes more to luck than to the disciplined will that guides successful somaesthetic practices, and the essay argues that for it to function as a somaesthetic practice, cultivators would need to adopt unconventional approaches that raise "the foodies' bar."

Resilient Cities Network · Resilient Cities Network · France

Article from the Resilient Cities Network describing Parisculteurs, the urban-agriculture support programme launched by the City of Paris in 2016. The '100 Hectares' charter has 82 partner organizations, and more than 50 projects have been realized with an equal number under development. Goals cited include shortening food supply chains, strengthening community cohesion, promoting healthy eating, food security, and ecosystem services.

Subramanian Senthilkannan Muthu · · Global

This abstract discusses how urban expansion and the separation of urban and agricultural areas increase energy demand for transporting food and goods. It notes that despite technological advances, a gap exists between energy demand and supply, even in advanced countries. The abstract concludes that reducing energy demand is a more realistic approach for sustainable development than solely relying on technological progress.

Peri-urban agriculture is exposed to pressures toward diversification and multifunctionality, developing differently depending on territorial features. A paper studies the case of Trentino, an Italian Alpine region where the ratio of urban to rural domain is heavily skewed toward the latter and farms face environmental problems that jeopardize their competitiveness in mainstream markets, comparing the development of alternative food chains there with other Italian peri-urban areas. The mountain environment makes it difficult for farms to standardize products to large retailers' requirements, but alternative food chains endorse and communicate to the market the typicality of products and farmers' savoir-faire, the two main factors of added value. Survey data from short food chain consumers show they are inherently more attentive to these product cues, as a result of a lifestyle more attached to identity and origins, and prouder of their territory. These findings confirm that, given its structural and cultural traits, alternative food markets in the Trentino area are meaningful for the survival and development of the local agricultural sector.

Research at the University of British Columbia (UBC), Canada, investigated whether rooftop gardens could reduce greenhouse gas emissions and food transportation carbon emissions. While edible landscapes could potentially assist with climate goals, they require careful selection of crops, buildings, and resources. Preliminary calculations indicated that rooftop and community gardens would do very little to reduce the UBC campus's dependency on imported food.
