This paper examined three types of locally oriented Short Food Supply Chains (SFSCs) in southern New England and their spatial alignment with demographic factors. The findings indicate that pay-as-you-go operations are more prevalent in predominantly White areas and, to some extent, higher-income areas. Box share arrangements (community-supported agricultures) showed stronger associations with educational attainment. The study concludes that local food availability is a systematically uneven phenomenon, varying with both outlet type and social characteristics.

This study examined how local government actors pursue urban agriculture (UA) policies in the Brazilian cities of Recife, Rio de Janeiro, and Curitiba, using a comparative case study approach based on key informant interviews and documents. It found that certain municipal bureaucrats act as "policy entrepreneurs," playing pivotal roles in creating, maintaining, and adapting UA policies. They employ strategies such as collaborating with civil society, forging partnerships within and outside of government, and framing proposals within international policy guidelines.

This study examined the perceived links between Community Supported Agriculture (CSA) and local food systems (LFSs) among consumers in 13 communities in the Southeastern United States, using survey responses. It found that residents were more aware of CSA if they knew about other direct markets or were exposed to local food campaigns. Consumers also evaluated CSA performance more positively if they had similar evaluations of direct markets and experience with on-farm activities, with these patterns varying by location.

This descriptive, quantitative study investigated the relationship between various Communities Supported Agriculture (CSA) variables in Southeastern Brazil using Structural Equation Modeling. The study confirmed that socioeconomic characteristics positively influence CSAs’ performance. However, limitations were identified regarding the data collection method and difficulties imposed by the Covid-19 pandemic.

Hayley Birss · Social Epistemology · Canada

This study examines Infarm's vertical farming practice, a venture capital-backed solution for climate change mitigation, by mapping its actor-network. The analysis reveals that Infarm's vertical farming and its climate change mitigation logics are shaped by venture capital and its biopolitical epistemology of valuation. This framework conceptualizes life, biology, and climate in terms of political economy, indicating that economic viability is a primary driver.

Baltimore, United States, has developed urban agriculture policies over the last decade, integrating them into a food systems approach to sustainability. Policy development covered zoning, permitting, land leasing, and soil regulations. However, challenges were encountered regarding staffing, funding, resident engagement, and differing city agency priorities, especially concerning land access. The experience highlights the importance of mainstreaming food policy into urban planning.

Rob Roggema, Aleksandra Krstikj, B. J. Erazo Flores · Nutrients · Mexico (Monterrey)

This study in the Noreste of Mexico, focusing on Monterrey, investigated spatial and non-spatial barriers to adopting healthy diets and accessing plant-based foods. Findings revealed significant disparities in food access across the Monterrey metropolitan area, with central urban zones having superior access to fresh foods compared to suburban and peripheral regions. This inequality disproportionately affects marginalized areas with higher poverty rates, worsening food insecurity.

This scoping review explored factors associated with Community Supported Agriculture (CSA) participation among low-income households in the United States. Analyzing 18 articles, findings suggested that women may be more likely than men to enroll in CSA. A lack of familiarity with CSA may hinder enrollment, whereas more education and self-efficacy for food preparation may facilitate participation.

Marcos Xavier · Boletim Campineiro de Geografia · Brazil (São Paulo)

This article aims to present peripheral urban agriculture in the outskirts of São Paulo, Brazil, as an element of the lower circuit of the urban economy. These agricultural activities, carried out by the city's poor, exhibit forms of organization and methods of practice specific to the urban context and participate in the dispute over the appropriation and use of urban space.

Arnaldo Monteiro, Neusa Barbosa, Rosimeire Pereira, Josimar Cardoso · International Journal of Research in Agronomy · Brazil (São Paulo)

This 12-month study (March 2022-February 2023) at the University of São Paulo, Brazil, evaluated the productivity, water efficiency, and economic viability of a media-bed aquaponics system compared to conventional hydroponics and soil-based cultivation. Lettuce and basil were grown alongside Nile tilapia. Aquaponics used 78.2% less water than soil-based production and 22.1% less than hydroponics per kilogram of produce. Lettuce yields in aquaponics reached 4.83 kg/m², slightly below hydroponics (5.12 kg/m²) but well above soil cultivation (3.27 kg/m²), and the aquaponics unit achieved economic break-even at month 9 and returned a 14.3% annual profit margin.

Martin Bailkey, Rosalind Greenstein · Urban agriculture · United States

This paper reviews “Farming Inside Cities: Entrepreneurial Urban Agriculture in the United States” (2000) by Jerry Kaufman and Martin Bailkey. This report was one of three concurrent research studies on for-market urban agriculture as a viable reuse of vacant land in major US cities. While its practical nature and description of urban agriculture's opportunities and challenges remain relevant today, it does not explicitly state the value of farming as a vehicle for social equity and food justice in urban communities of color.

This study investigated the connection between local farmers markets (FMs), community-supported agriculture (CSAs), and physical well-being at the state level across the 50 states of the United States. Analyzing 2016 data from the United States Department of Agriculture using an ordinal logistic regression model, the study found an inconclusive relationship at the state level. While local FMs and CSAs may increase physical well-being, this study did not find such an increase.

Domenic Vitiello · Urban agriculture · United States

US cities have developed urban agriculture support systems reflecting competing values, with some prioritizing public good and others economic gains. A chapter reflecting on urban agriculture planning in Chicago and Philadelphia notes that institutional structures significantly impact equity and justice. The study indicates that the existing urban agriculture support systems in these cities may not adequately promote equity and justice.

A systematic review of 34 studies (37 articles) from 2000-2020 evaluated the impact of local food system (SVC) models on food and nutrition security among low-income populations in the United States. Farmers market interventions were more extensively evaluated than other SVC models, with fruit and vegetable intake being the most measured outcome. Barriers to SVC use included lack of program awareness, limited accessibility, and cultural incongruence, while facilitators included health-promoting environments, community cohesion, financial incentives, and high-quality produce.

A study of 18 urban community gardens in Central Coast, California, USA, used gardener surveys and field measurements to evaluate food production and its distribution. Gardeners produced an average of four pounds of food per week, saving an estimated $16 USD weekly. However, gardeners with greater food insecurity (larger families or lower incomes) were not the largest producers, indicating uneven benefit distribution despite high overall productivity.

This study reviewed and categorized 73 food asset maps in Canada based on their included food assets and design characteristics. Most maps included built environment assets like grocery stores and food banks, as well as agriculture-based natural food assets such as farms, community gardens, and orchards. However, representations of Indigenous-focused food assets and non-agriculture-based natural food assets like forests, water bodies, and foraging areas were generally lacking. This lack of Indigenous perspectives reinforces the values of a settler-colonial food system within food asset maps.

To investigate the economic potential of urban agriculture in existing public green spaces, gross economic returns per hectare from horticultural crops were calculated from eight sources and fourteen growing approaches. Findings showed returns ranging from $22,249 to $360,000 USD per hectare annually, with several small urban agriculture businesses achieving gross returns of $150,000-$300,000 per hectare. The study concludes that urban agriculture in existing public green spaces offers opportunities to increase economic viability, alongside additional benefits like job creation, local food availability, education, training, health, and environmental improvements.

This study examines the role of urban gardens in Cachoeiro de Itapemirim, Espírito Santo, Brazil, exploring their economic, social, and environmental dimensions. Urban gardens mitigate environmental degradation, promote biodiversity, and have the potential to generate employment and income opportunities for local residents, while reducing food costs. Through the efficient use of local resources like idle land and organic waste, these gardens yield significant environmental benefits, including reduced pollution and improved air quality, and foster sustainable agricultural practices.

Matthew L. Richardson, John Taylor, Megan J. Thompson, Anusuya Rangarajan, Mamatha Hanumappa, Neith G. Little · PLoS ONE · United States (Northeastern United States)

This online survey of 394 urban growers, primarily in the Northeastern United States, profiled growers and assessed urban agriculture's state, identifying needs and challenges. Most growers were white (non-Hispanic), under 45, well-educated but without agriculture degrees. Urban agriculture was dominated by small non-profits and home/community gardens. A critical finding is that urban growers face diverse barriers, with the most common being land availability and long-term access in urban areas, and many reported low revenue or operating at a net loss.

This study assessed São Paulo's urban agriculture (UA) potential using an Ecosystem Services (ES)-based approach, combining ES spatial mapping and a producer survey at 49 UA sites. Results showed natural habitats and anthropic areas within urbanized land, especially in the south, with high habitat quality scores. Nine ES were identified: food supply, commercialization, income generation, waste mediation, lifecycle maintenance, soil formation, leisure/social, well-being, and education.

Uilma dos Santos Ramos, Heron Ferreira Souza · Revista Macambira · Brazil

This study investigated the meanings of work relationships in the Ipiaú community garden in Bahia, Brazil, which was established in response to 1980s unemployment. Using semi-structured interviews and thematic content analysis, the research found that "freedom" emerged as a central meaning of work. The educational character of the work was reinforced through the experience of values and practices supporting an "Other Economy."

Jairus Rossi · Sustainability · United States

A study used survey responses from residents in five US South communities in 2019 and 2022 to evaluate how consumer perceptions of local food systems changed after COVID-19. Using a treatment effects model with propensity score matching, residents became more aware of most local market channels, such as specialty retail stores and Community Supported Agriculture (CSA). Some residents also showed a more positive perception of markets providing fresh vegetables to low-income residents and desired more investment in markets making local products available.

This paper presents clay 3D-printed hydroponics as an urban farming and architecture proposal, reporting on a pilot study conducted in Atlanta, Georgia. It positions additively manufactured clay hydroponics as a soilless agriculture technique and discusses it in relation to urban food self-sufficiency. The paper is described as the first in a series on technology implementations.

Iara Rafaela Gomes · Sociedade & natureza · Brazil

A study examining agricultural activity, in particular family farming, in the Fortaleza Metropolitan Area (FMA) of Ceará State, Brazil. Drawing on primary and secondary data on producer profiles and agricultural and food-processing establishments in the region, it identifies key issues in production and food systems within the FMA. The study presents the production strategies used by family farmers, the challenges they face, and opportunities they identify, and argues that examining agriculture in metropolitan areas links socio-spatial and socio-environmental problems and points toward cross-sectoral public policy.
