A study in southern Benin surveyed 60 onion farmers across three municipalities (Grand-Popo, Cotonou, Sm-Kpodji) using quantitative and qualitative methods. It found onion production to be financially profitable, with performance enhanced by age, experience, and producer group membership, and improving socio-economic and food situations. However, significant constraints include financial, institutional, organizational, property, and production-related issues.

Camille Frazier · Journal of Political Ecology · India (Bengaluru)

This article examines the motivations and practices of organic terrace gardeners (OTGians) in Bengaluru, India, who grow food in private spaces. While OTGians successfully create a vibrant community driven by food safety and environmental concerns, their efforts are limited to the middle class due to class-specific concerns and production practices. The study highlights that urban gardening in this context remains an intervention primarily for the middle class.

Zsofia Mendly‐Zambo, Dennis Raphael · Social Policy and Society · Canada

Household food insecurity (HFI) affects over 1.7 million Canadian households, yet government action to address it has been remarkably limited. Non-governmental efforts like food banks and community gardens have depoliticized HFI, complicating solutions. The study argues that the critical materialist political economy discourse, which is least considered, best explains HFI in Canada and offers the most effective response.

Khadija Benis, Rukaia Gashgari, Adnan Alsaati, Christoph Reinhart · DSpace@MIT (Massachusetts Institute of Technology) · Saudi Arabia (Riyadh)

The Urban Foodprints (UF) methodology was applied to assess the environmental sustainability of high-yield urban agriculture in Riyadh, Saudi Arabia, focusing on tomatoes. While urban production in high-yield greenhouses could reduce Global Warming Potential by 9% and water savings were significant, the energy needs of these greenhouses were considerably higher than the baseline. This indicates a trade-off where environmental benefits are partially offset by increased energy consumption.

Dona Pickard · International Journal of Sociology of Agriculture and Food · Bulgaria (Plovdiv)

This paper analyzes an urban agriculture case in Plovdiv, Bulgaria, where the municipality cleared over 2 hectares of long-tolerated allotments without involving users, despite NGOs promoting urban agriculture as a social innovation. The case exemplifies barriers hindering social innovation, particularly regarding governance, as the eviction occurred without discussion about the future of urban agriculture. This suggests a lack of civic participation and access to resources for deprived groups.

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.

Gabrielle Roesch‐McNally, Jacqueline Ann Nester, Andrea Basche, Eric Christianson, Emily Zimmerman · Lincoln (University of Nebraska) · United States (Iowa)

Story County, Iowa, despite being in a highly agriculturally productive state, faces significant food insecurity. In 2014, 15.2% of its residents (nearly 14,000 individuals) were food insecure, with 45% of them not qualifying for government assistance. The county dedicates only 2.4 acres of cropland per thousand residents to fruit, vegetable, and nut production, significantly lower than the US average of 32 acres, highlighting a paradox of hunger amidst agricultural abundance.

Tinashe P. Kanosvamhira · Development Southern Africa · South Africa (Cape Town)

Based on a literature review, urban agriculture and its organizational forms in Cape Town, South Africa, were explored. A lack of effective coordination of initiatives among supporting actors was suggested to be a significant pitfall in the development of urban agriculture. Furthermore, the failure of farmers to self-organize was identified as equally detrimental. Therefore, improved synergies between state and non-state actors are called for to enhance the gains of urban agriculture.

Georgia Pollard, James Ward, Philip Roetman · Sustainability · Australia (South Australia)

This paper explores the economic sustainability of home food gardens in South Australia using new data from the Edible Gardens project online survey. While saving money is a top motivation for many respondents, the study notes that it remains to be seen whether current gardening practices actually support this aspiration. The paper concludes that more work is needed to measure the full costs of different gardens to better predict their financial accessibility and economic sustainability.

In-Kyoung Hong, Young Chae, Yoonah Jang, Sangmi Lee, Jung Nam Su · Journal of people, plants, and environment · South Korea

A study in South Korea surveyed 115 urban citizens to analyze urban agriculture's effects based on income level, identifying socially sustainable, negative, and economically sustainable factors. Findings showed psychological stability, connection with nature, and local agricultural vitalization correlated significantly with income level. However, the negative effect of urban agriculture showed no significant correlation with income level.

Percy Toriro · · Zimbabwe (Harare)

This chapter explores the governance of urban food production in Harare, Zimbabwe, from 1890 to the present. Evidence indicates that while the practice has gained general acceptance through shifting positions over the years, the status of producers remains uncertain. This uncertainty stems from the lack of full incorporation of urban food production into city plans by planning officials, whose values are out of sync with Harare's lived reality.

Shannon Donovan · Case Studies in the Environment · United States (Anchorage)

A multi-faceted needs assessment, including a community survey, stakeholder workshop, and key informant interviews, was conducted in Anchorage, Alaska, to explore the strategic expansion of its community garden system. The study found that demand for community gardens far outweighs supply. To sustainably meet diverse needs, expansion efforts should focus on accessible locations, gardener capacity building, and strengthening partnerships.

The process of systematizing the experience of AUÊ!, the Urban Agriculture Study Group at the Federal University of Minas Gerais, helped to record and critically reflect on the group's trajectory. This systematization made it possible to identify the qualities, potentialities, and gaps in the group's performance.

Dan Yu, Dongyan Wang, Wenbo Li, Shuhan Liu, Yuanli Zhu, Wenjun Wu, Yongheng Zhou · Sustainability · China (Changchun)

This paper assessed the landscape ecological security (LES) of peri-urban cultivated land in Changchun City, China, at three time points, considering both cultivated and surrounding landscapes. Results showed that urbanization affected the peri-urban cultivated landscape, with metrics like patch density and edge density progressively increasing for cultivated land within 20 km of the urban center. This indicated elevated fragmentation and vulnerability, and the study concluded that decreased LES of cultivated land impedes sustainable peri-urban agriculture.

Kamran Zendehdel, Lorraine Clarke, Xiaochu Hu, Richard Hess · Journal of Extension · United States (Washington, DC)

A 2015 youth urban agriculture workshop for students from underserved areas in Washington, DC, revealed gender and racial differences in perceived knowledge gain and intended behavior change. Female students and Black students reported about half-grade higher (0.43–0.63 points) scores for knowledge change, while only female students showed an increase in intent to change behavior. These results suggest that female students may learn at a faster rate than males and that experiential learning aids Black students in gaining knowledge.

Mitch Rose · Antipode · United States (Detroit)

This paper discusses the Detroit urban farming movement, conceptualizing the economy as an over-productive and wasteful system of energy exchange. It argues that the inefficient, redundant, and wasteful nature of urban farming in Detroit is an appropriation of potentialities within the general economy. The study highlights that diversity is not a result of positive relations but emerges from the prolific nature of the general economy.

장인수, 서동주, 김홍석 · 지역연구 · South Korea

This study in South Korea explored ways to revitalize urban agriculture based on empirical analysis of experience and subjective perceptions, defining its main functions as enhancing ecological, landscape, and participation values. Survey results showed that exposure to urban agriculture information was higher in large cities, and participation experience was higher with larger residential spaces. While positive responses were high for urban agriculture's functions, negative responses were high regarding perceptions of the surrounding residential environment.

This study in Accra Metropolis, Ghana, compared Anopheles gambiae s.l. species composition and insecticide resistance between two vegetable-growing and two non-vegetable growing areas. All A. gambiae s.l. populations tested were resistant to five insecticides, with lower mortalities observed in vegetable-growing areas (e.g., 2.6% and 12.5% for deltamethrin) compared to non-vegetable areas (36.2% and 38.9%). Anopheles gambiae s.s. and Anopheles coluzzii were dominant in vegetable-growing areas. The findings indicate that urban agriculture contributes to the development of insecticide resistance, which needs consideration in vector control strategies.

Solomon Tulu Tadesse, O. Oenema, Christy van Beek, Fikre Lemessa Ocho · Nutrient Cycling in Agroecosystems · Ethiopia

This study investigated the diversity and nutrient balances of urban and peri-urban agriculture (UPA) systems in three Ethiopian cities, using data from 425 households (Addis Ababa: 175, Adama: 126, Jimma: 124). It identified six farm types, including commercial livestock (cLS) and subsistence field crop (sFC) systems. The study found that cLS systems accumulated significant nutrients (450 kg N, 85 kg P, 260 kg K ha−1 year−1) with low use efficiency (26% N and P, 15% K), while sFC systems depleted nutrients (−30 kg N, −17 kg K ha−1 year−1) with high use efficiency.

Natalia Matesanz Ventura · · United States (New York City)

This article examines over fifty self-managed community gardens in Loisaida, New York, which form an informal network combining "affection" and "dissidence" to create "affect-dent" spaces. These gardens, established since the 1960s, reconfigure public space by opposing administration, the real-estate market, media invasion, and the appropriation of public space by the private sector. The study highlights how these spaces challenge dominant power structures and serve as a reference in contemporary architecture of the common.

A survey in the Western Transdanubia region investigated major problems in Community Supported Agriculture (CSA) within short food supply chains, involving farmer organizations and consumers. The analysis identified the insufficient market power of CSA organizations as the most influential factor. This finding suggests a significant constraint on the effectiveness of CSA models in the region.

Dissolved phosphorus (PO4 3-) and nitrogen (NO3- & NH4+) losses in leachate from experimental raised-bed garden plots were measured. Plots receiving cow manure compost showed high PO4 3- concentrations (5-11 mg/L), while municipal organics compost plots had concentrations an order of magnitude lower (0.5-1.2 mg/L), and no-compost plots had 0.3 mg/L. Phosphorus lost through leachate and harvest accounted for only 1-10% of total applied phosphorus, indicating soil build-up was the dominant fate. This study illustrates a potential trade-off in urban agriculture between crop production and efficient phosphorus recycling from urban food waste.

Rodrigo Clemente GOIS, Flamarion Dutra Alves, Evânio dos Santos Branquinho · Geografia (Rio Claro) · Brazil (Alfenas)

This article aims to characterize urban and peri-urban agricultural activities in Alfenas, Brazil, and analyze the encroachment of real estate speculation on these properties. It notes that Alfenas has seen an increase in residential developments occupying areas previously used for livestock and agriculture. The study suggests organic farming as a viable alternative to mitigate socio-environmental problems arising from this encroachment.

Marina Silalahi, Lauresius Sihotang, Sunarto Sunarto, Fajar Adinugraha, Adisti Ratna Puri · · Indonesia (Cianjur)

A survey was conducted among 21 students at Pusaka Junior High School in Cianjur, Indonesia, to assess their understanding of hydroponic farming. Students knew the definition, methods, maintenance, and production of hydroponic plants, but literally interpreted that media like sand could not be used. While many students had experience with hydroponic farming, they claimed it was more expensive than conventional farming.

Annie Svensson · · Sweden

This research investigated the economic sustainability of 14 Community Supported Agriculture (CSA) farms in Sweden through interviews. The study found that Swedish CSA farms had difficulties covering labor costs and suffered from inefficiency, indicating weak economic sustainability. The study did not identify specific approaches or business models that were more conducive to higher profitability.
