The "Grow Your Groceries Home Garden" intervention program, implemented in Chicago, United States in 2022, aimed to improve food access in food-insecure communities. A longitudinal investigation over two annual cycles surveyed 46 participants, complemented by focus groups with 9 participants, to evaluate food access, cost savings, health, and socioemotional outcomes. While results on improved gardening confidence over time emerged non-significant, participants reported increased food access, cost savings, healthier eating, stress reduction, and strengthened relational bonds.

A review of 22 studies (2001-2024) across six countries, primarily the US and Canada, examined how high school garden programs support adolescent food security and resilience. Findings indicated contributions across multiple socio-ecological levels, but uneven implementation significantly constrained their overall impact. Specifically, opportunities for shared decision-making were limited, and short-term, inconsistent support for policy, funding, and governance structures restricted long-term effectiveness.

A study in RT 11, Belimbing Sub-district, BTN PKT Bontang Housing Complex, Indonesia, examined the implementation of the Neighborhood Association (RT) fund policy for community empowerment programs. Despite adequate funding, community participation in programs such as urban farming remained relatively low, typically 60–75% of the 20-person quota. While communication, resources, implementer disposition, and bureaucratic structure functioned relatively well, increasing community participation remains a challenge due to socioeconomic factors like work commitments and time constraints.

This qualitative study explored facilitators and barriers to implementing an electronic redemption system in a Healthy Food Incentive (HFI) program among farmers' markets, farm stands, and community-supported agriculture. Semi-structured interviews with HFI staff identified six facilitators and ten barriers, including a cumbersome registration process, technological difficulties, the risk of losing customers, and insufficient capacity. The evaluation highlighted the necessity of localizing technology dissemination.

This study in Surabaya, Indonesia, investigated hydroponic cultivation among two farmer groups, Kelompok Tani Anggrek (19 members) and Kelompok Tani Sawi (14 members). It found that the farmer groups were not yet optimal in hydroponic cultivation due to a lack of understanding, minimal assistance, and improper use of fertilizers and seeds. However, knowledge among the farmer groups increased by 51.52% due to extension activities, and most respondents agreed that hydroponics is a suitable solution for food security and that assistance had a positive impact.

Kinga Kimic, Magdalena Błaszczyk · Sustainability · Poland (Warsaw)

This study identified and assessed vegetable cultivation projects submitted to the Warsaw Participatory Budget (WPB) between 2015 and 2023. The research classified projects into six types and evaluated them across social, functional, ecological, and economic dimensions. The results showed that vegetable-related projects in the WPB were decidedly niche, with only 101 initiatives submitted and 31 implemented, primarily focusing on education for children rather than direct food access.

The capacity of Family Allotment Gardens (FAGs) in Warsaw, Poland, to provide air-pollution filtration and microclimate regulation was quantified. Particulate matter, air temperature, and relative humidity were measured inside and outside three allotment complexes in autumn 2023. Results showed a moderate reduction in PM concentrations inside gardens (by about 2 µg/m³) and slightly higher humidity (2.1%). However, the cooling effect was weak (less than 0.3 °C), indicating a limited spatial range under autumn conditions.

A choice-based survey of over 600 US residents from Rhode Island examined preferences and perceived value for green rooftop (GR) space allocations for agriculture, solar energy, and recreation. Latent class modeling revealed that Class 1, representing 20% of respondents, was generally unsupportive of GR installation and expressed disutility towards GR space allocation for solar energy. Both classes uniformly favored allocating GR space for agriculture production and showed a positive willingness to pay for this feature.

Serafina Stone, Jeremy Farr, Damian Hine, Yasmina Sultanbawa, S. K. Fyfe · Local Environment · Australia (Brisbane)

This research investigated how 16 members of four urban community gardens in Brisbane, Australia, derive value from their involvement in relation to the food system, using semi-structured interviews and participant observation. The findings indicate that while urban community gardens alone cannot address food security needs, they provide spaces for building community, generating social capital, connecting to nature, and developing food systems education. These benefits are contingent on the gardens' continued existence and primarily extend to those able to participate.

In Dar es Salaam, Tanzania, the utilization of faecal sludge derived compost (FSDC) by urban farmers remains limited due to farmers' prejudice and hesitance. This study investigated factors influencing FSDC acceptance through a cross-sectional survey of 76 urban farmers. Results indicated that garden location in communal areas, income generation as the primary farming purpose, and accessibility of soil inputs were significantly associated with FSDC acceptance. Farmers' awareness and experience also played important roles.

Magdalena Raftowicz, Mirosław Struś · Sustainability · Poland

An empirical study in Poland, based on a critical literature review and a 2024 CAWI (computer-assisted web interview) survey of CSA producers, examined whether social capital theory explains food producers' engagement in Community-Supported Agriculture (CSA) and whether this holds in practice. It found that social capital theory does explain the mechanisms underlying CSA engagement, with implications for local food system and small-farm policy, but that because of Poland's low level of social capital, the CSA model there remains only a niche complement to traditional agriculture, functioning primarily for a narrow group of socially and environmentally conscious consumers and small producer clusters.

A 2024 systematic survey of 217 urban farming households in Yogyakarta City, Indonesia, used Stata 19 for hypothesis testing and SPSS 27 for descriptive statistics, running a multiple linear regression of net urban farming income against 22 variables covering sociodemographics, farm structure, input management, biotic stress and institutional support (R2 = 0.7448). Eleven variables had a significant effect, with farm size the most favorable factor, followed by financial support, seed subsidies and technical aid; gender and family size also showed positive effects. Crop type correlated negatively with income, and biotic stress — particularly pest type and severity — substantially reduced income, while training and market access were not statistically significant.

A study in Makassar City, Indonesia, evaluated the multidimensional sustainability of urban agriculture (UA) through expert discussions and semi-structured interviews with 23 purposively selected stakeholders including academics, practitioners, urban planners, legislators and government officials. A Multidimensional Scaling (MDS) approach compared sustainability indices from two previous studies, supplemented by prospective and interdependence analyses to identify key leverage factors. Results showed the overall sustainability status of UA in Makassar during 2016-2020 remained "less sustainable," with a multidimensional sustainability index of 43.02%; the ecological (51.84%) and technological (65.09%) dimensions improved to moderately sustainable status, while the economic (46.15%), social (49.81%) and institutional (39.20%) dimensions showed declining sustainability performance. The study proposes three policy directions: strengthening UA planning and management systems, improving institutional coordination among stakeholders, and expanding UA's socio-economic and environmental functions.

Liz Ignowski, John Luis Lagdameo, Liel Gonzalez, Arma Bertuso, Pepijn Schreinemachers · Urban Agriculture & Regional Food Systems 11(1) · Philippines (Quezon City, Metro Manila)

A quantitative survey of 300 urban food producers in Quezon City, one of the 17 cities of Metro Manila, examining who practises urban agriculture, the methods and technologies used, the challenges met and the benefits gained. Production is mainly small-scale and subsistence-oriented, with commercialisation limited except among those with access to agricultural land. Self-produced food does increase access to fruit and vegetables, but participation reflects economic vulnerability rather than food sufficiency, and both scale and commercialisation depend strongly on land access — a structural barrier in dense cities. The authors conclude that urban agriculture in Quezon City acts as a safety net rather than an income source, while also providing enjoyment and stress relief, and that urban food-security policy should be realistic about the limited role of urban food production.

Pearson, Natalie · British Food Journal · 英国（食を育てる人びとへの質的調査）

It is often argued that growing one's own food reduces household food waste by raising appreciation of food, but focused research on this is lacking. Using thematically analysed qualitative surveys with a privileged sample of food gardeners, this study finds the relationship more complex than proposed: for these gardeners, growing their own food can also decrease appreciation of food and create waste because of the challenges of growing, processing and storing it. Food gardening could nonetheless become an instrumental waste-prevention practice if growing is made easy and convenient, gardeners are given opportunities to work together, more channels exist for sharing surplus, and cooking skills improve. Its contribution is to critique the assumption that growing your own always leads to appreciation of food and less waste.

A systematic review of the irony between abundant arable land and persistent hunger in African cities. It asks why a disproportionate share of urban residents do not produce their own food, even as food insecurity rises with heavy reliance on market-bought food, high poverty and rapid urbanisation, screening peer-reviewed literature via PRISMA and five inclusion benchmarks to clarify the debate on low uptake of urban agriculture.

A systematic review (PROSPERO CRD42021254450) searching four databases to 19 February 2025, with duplicate independent screening, risk-of-bias assessment and certainty grading, on food-based interventions that could reduce household food insecurity (HFI) in Canada. Exposure to food voucher programmes may reduce HFI, but exposure to food box, community gardening, school food, hunting and fishing, and food charity programmes may have little to no effect on HFI. The authors conclude that because HFI is primarily an economic problem, food-based responses are unlikely to have a major impact on overall HFI and a more comprehensive public policy approach is required. This is direct counter-evidence to framing community gardens as a food-insecurity intervention.

Marisol Silva-Vera, María de Jesús Jiménez González, Laura Varela Almanza · JÓVENES EN LA CIENCIA · Mexico

A quasi-experimental study in Mexico with 21 adults over 65 evaluated a community urban garden intervention for nutritional status. Participants showed increased nutrition knowledge, a 47.7% rise in vegetable intake, and a 23.8% increase in physical activity. However, anthropometric variables did not show significant differences, indicating limited impact on physical measurements despite positive changes in knowledge and habits.

Juliane Forßmann, Simon Goebel · Zeitschrift für Flüchtlingsforschung · Germany

An urban gardening project in a residential facility for up to 230 refugees in Germany aims to counteract precarious living conditions. While the garden offers a low-threshold space for knowledge exchange on resource-saving cultivation, biodiversity, and health promotion, this paper also reflects on the project's limits.

Limachi Pérez, Vicente · Macedonian Journal of Medical Sciences (University of Skopje) · Bolivia (Cochabamba)

This study examined the influences of family, school, and sociodigital networks on environmental awareness among secondary school students in urban and rural Cochabamba, Bolivia. Data from three schools showed students' environmental concerns varied by region, and the internet was their primary information source. Despite isolated initiatives like school gardens, schools did not effectively integrate environmental education into the curriculum, limiting its formative impact.

This research, conducted in San Juan, Puerto Rico in July 2019, investigates how women experienced the impacts of Hurricane Maria on their urban farms (huertos urbanos). Findings show that while many women enjoy urban farming and it provides fresh produce, almost all women farmers experienced a decline in volunteer participation a few years after the farms' establishment and even more so after Hurricane Maria. Despite this, many women described the urban farms as very important for community food cultivation and gathering.

This study investigated Spanish consumers' perceptions of five lettuce cultivation systems using explicit and implicit methods with 105 participants. Local/small agriculture was most favorably regarded, while urban community gardens were perceived as less safe for lettuce production. High-tech greenhouses were considered safer but less sustainable, and vertical indoor farming elicited a surprise reaction due to low familiarity.

This field study, involving 20 residents of Dom Pedrito/RS, Brazil, who practice home gardening, aimed to identify motivational factors, difficulties, and benefits. The main difficulties reported were the time required for cultivation and the presence of pests and insects. While benefits included consuming healthy food, health improvements, and supermarket savings, the significant challenges of time commitment and pest management indicate limitations to the widespread positive impact of home gardening.

This review explored how community connectedness influences sustainable eating, particularly meat consumption. It found that while community ties can encourage pro-environmental behaviors and support plant-based diet initiatives, a strong connection to one's community may also hinder the adoption of environmentally friendly diets by reinforcing meat-heavy culinary traditions. The potential for community connectedness to promote sustainable eating depends on factors like environmental awareness.

A qualitative study at State Elementary School 2 Metro Timur, Indonesia, explored the use of the surrounding environment as a Social Studies learning resource. While school gardens and community activities were found to be contextual and meaningful, obstacles included time constraints, unpredictable weather, poor student coordination, and limited facilities. The study suggests that environment-based learning has the potential to improve conceptual understanding and social skills, but faces significant limitations.
