This paper presents a methodology applicable to sustainable community actions, developed from seven years of experience with low-income communities in a Brazilian community garden. The methodology is based on participatory action research, systemic design, agroecology, food sovereignty, and solidarity economy principles. The study demonstrates the importance of integrated work among the elements of the quintuple helix model (society, government, industry, academia, and environment), but it does not detail specific challenges or limitations regarding governance.

In Kampung Ngemplak Sutan (Kampung Sayur Organik), Surakarta, Indonesia, sustainability of the local urban farming initiative was evaluated using primary data from observation, questionnaires and interviews plus secondary data, analyzed with Multidimensional Scaling and Rapid Appraisal for Sustainability (MDS/RAPS). The socio-cultural dimension scored highest at 75.44 ("very sustainable"), while the economic dimension scored lowest at 56.71 ("fairly sustainable"); the study also noted that urban farming there functions mainly as a side activity that receives limited attention and that community participation has been declining.

A 2024 paper reports on an educational practice with elementary school students at a community garden at IFG-Anápolis, Brazil, framed around "omnilateral formation" and critical environmental education. Through periodic visits, workshops, and discussion sessions, the practice addressed problems arising from the use and consumption of pesticides in food. It reports that the critical environmental education approach was significant in revealing the latent meanings behind an agribusiness food market based on unrestrained pesticide use.

A chapter examines the role of technology across the European 'agrifood' system, an umbrella term for the agriculture, horticulture, food, and drink sectors. Placing the dysfunctional consequences of making economic growth the driver of food-system organization in historical context, it shows through a case study of a daffodil farm in South West England that when technology is deployed as an engine of efficiency, unbridled growth, and profit maximization, it vastly improves productivity through worker quantification—time, motion, and output tracking—while transforming worker-nature relationships in exploitative ways. By contrast, when used to prioritize non-exploitative, collaborative relationships, technology can support sustainable well-being and ecological production, illustrated through three alternative food network cases: a UK community garden, a UK Community Supported Agriculture scheme, and a network of social agricultural cooperatives in Italy.

A review combining scientific literature analysis and interviews with urban farmers examined urban farming models including community, indoor, rooftop and vertical farms using techniques such as aeroponics, hydroponics and aquaponics. It found that sustainability and yield remain major challenges to fully realizing urban farming's potential, identifying limited land and water resources, pest and disease incidence, financial constraints on setup and maintenance, knowledge and skill gaps among participants, and a lack of effective collaboration between universities, government and industry as the key barriers.

A commentary on the current state of urban agriculture implementation in large Indonesian cities, the initiatives underway and the mechanisms for pursuing stated goals. It identifies land scarcity, inadequate urban agricultural infrastructure, financial constraints, and regulatory and administrative problems as the major obstacles to implementation. It also states that urban agriculture improves quality of urban life by providing fresh, healthy food and fostering community engagement, and cites Singapore, New York and Ghana as examples showing the importance of policy support, innovation and community involvement.

Two years of monthly water sampling and hydrological monitoring at the outlet of the Wadi Guenniche watershed (86 km², with rainfed cereal, legume and orchard cultivation and irrigated market gardening) in northern Tunisia, a tributary of the Bizerte coastal lagoon, tested for 469 pesticide active ingredients and metabolites. Twenty-nine pesticide active ingredients and 2 metabolites were detected in the water, 24 of which are authorized for use in Tunisia; 14 of the authorized substances had never before been mentioned in farmer surveys. The five most frequently detected herbicides and metabolites were AMPA (100%), glyphosate (94%), simazine (94%), 2,4-D (70%) and deisopropylatrazine (DIA, 47%). The detection frequency and concentration range suggest phytosanitary pressure and water contamination comparable to the northern Mediterranean shore, indicating a need for further study of pesticide use and fate on the southern shore, particularly in Tunisia.

Treated wastewater from the plant serving Bole Lemi Industrial Park (BLIP) in Addis Ababa, Ethiopia was sampled at the treatment plant's influent and effluent and analyzed using a treated wastewater quality index (TWWQI) to assess suitability for urban irrigation agriculture. The aggregate TWWQI classified the water as 'very poor' for urban irrigation agriculture, with heavy metals contributing 85% of that grade, nutrient load 4%, salinity 8%, and miscellaneous contaminants 4%. Discrete indices varied: heavy metals scored 'very polluted', nutrients 'excellent', salinity 'poor', and miscellaneous contaminants 'good'. Contaminant removal efficiency ranged from 30% to 100% (58% in aggregate), and some contaminants showed higher concentrations in the effluent than the influent, indicating the treatment plant failed to remove them. Cr3+, Cl− and TDS contributed most to the poor rating, and the plant was found to need upgrading to increase removal efficiency.

Using a GIS-based risk assessment methodology, this study develops a quantitative food-insecurity scale for the most vulnerable urban populations, calculating risk as a combination of social vulnerability and hazard (difficulty of access to food distribution), and applying the model to two case studies: southeast Washington, D.C., in the United States and Puente de Vallecas in Madrid, Spain. A Social Vulnerability Index was computed from average income, education level, unemployment rate, and age, while hazard values were derived from proximity to supermarkets. The analysis identified high-risk food-insecurity areas in both neighborhoods requiring urgent intervention measures. In Puente de Vallecas, census tract 07913143 was identified as a high-risk hotspot with a Social Vulnerability Index of 1.646495 (range 0.901–3.223) and a risk value of 3 (range 3–10); in southeast D.C., tracts 7601 and 7605 were selected as high-risk zones for further study, with Social Vulnerability Index values of 2.221 and 1.737 (range 1.040–3.525) and risk values of 2 and 5 (range 0–10), respectively. The study also identifies a general shortage of areas combining residential and commercial use and limits on public transport availability in the food-insecure urban areas studied.

In New Jersey, 50 food desert areas face the most severe food insecurity across both rural and urban contexts. This study identified nine barriers to implementing urban agriculture initiatives in New Jersey's urban food deserts, using a sequential quantitative analysis combining a survey of food systems professionals with a GIS-based spatial analysis to identify the most prevalent barrier. Working in partnership with New Jersey urban agricultural organizations, the study found that lack of funding was the most commonly cited barrier to expanding urban agriculture initiatives. The GIS-based spatial analysis found that high-priority barriers varied by region, but that all organizations identified funding, or lack of access to funding, as a significant barrier regardless of whether they operated in a low- or high-income neighborhood. The study concludes that policymakers must reevaluate the role of urban agricultural organizations in New Jersey's urban food deserts.

This study investigated heavy metal concentrations in soil and crop leaves from 23 urban gardens in Jinju, Korea, to assess suitability for cultivation. While average concentrations of As, Cd, Cr, Cu, Ni, Pb, and Zn generally did not exceed Korean guidelines, the Geoaccumulation Index indicated ongoing contamination by Cd, Cu, Pb, and Zn. A significant amount of Pb was introduced into some soils from the atmosphere, and continuous monitoring for heavy metals in urban garden soils is required for food safety.

This study on the local contract farming (LCF) movement in Switzerland is based on an ethnography of three LCF networks. The research focuses on the contract that formalizes the "promise of difference" and the redefinition of food quality and value. It acknowledges both the potential for transformation of LCF ventures and their clear limitations, aiming to foster discussions beyond simple statements of success or failure.

This community service activity focused on the Empelan Terbin Farmer Group in Denpasar City, which practices urban agriculture but faces challenges in distributing and selling its produce. The group's agricultural products were often only shared locally or discarded due to excess harvest, indicating a lack of effective sales channels. To address this, the activity provided training and assistance in digital marketing via Facebook to help the group introduce its products to a wider audience and generate profit for sustainable land management.

This article aimed to map authors discussing environmental aesthetics in urban agriculture research, inspired by Porteous's work. Using a bibliographic survey and visual representations, the study found no publications intersecting urban agriculture and environmental aesthetics. Research on urban agriculture and landscape was notably greater than on urban agriculture and aesthetics, and studies applying aesthetic theory to urban agriculture were very limited, especially in high-tech contexts like vertical farms.

This study mapped and characterized 82 urban and peri-urban agriculture (UPA) initiatives in Porto Alegre, Brazil. It found that educational and health-related initiatives with social and ecological objectives predominated. A significant finding was that only half of these initiatives were active at the time of the survey, with the rest being inactive or closed, indicating structural fragilities, especially in peripheral and less dense areas impacted by the COVID-19 pandemic.

A qualitative descriptive study with 13 fourth-grade students at MIN 1 Karanganyar, Indonesia, found that the Adiwiyata program's greenhouse initiative was not running smoothly due to a lack of funds. The students' ecoliteracy in the "head" and "heart" aspects needed improvement, as most did not habitually sort waste despite knowing types, and some lacked empathy for plants. However, students demonstrated ecoliteracy in the "hands" aspect through proper cleaning tool use, bringing supplies from home, and saving electricity and water.

This phenomenological study investigated the views and experiences of 9 headteachers and 9 teachers from 6 preschool institutions in Turkey and England regarding outdoor learning. It found that in Turkey, school gardens, equipment, and time spent outside are insufficient compared to England. While family participation in outdoor learning is more common in Turkey, teachers and headteachers there experience greater family pressure concerning child safety, illness, and dirty clothes, and feel anxious due to a lack of classroom assistance. Both countries showed insufficient inclusion of outdoor learning in vocational and in-service training.

From 2017 to 2018, University of California Agriculture and Natural Resources (UC ANR) researchers conducted a series of 16 workshops for urban farmers in California. The evaluation found that economic issues such as profitability and land access are among the greatest barriers for urban farming in California. While networking among participants was an unexpected positive outcome, urban farmers expressed a need for more opportunities for mentoring and building partnerships.

A discourse analysis of historical school garden texts in North America reveals that school gardens have not been welcoming or accessible to all children, despite persuasive research on the positive effects of nature-based learning. Historically, school gardens were used to serve adult agendas, including containing urban children, assimilating marginalized groups, and creating laborers, thereby reinforcing patriarchal, colonial, white supremacist, and eugenic aspirations. This study explores how these discourses culturally constructed childhoods and influenced children.

A study in Bandung, Indonesia, surveyed 321 households to assess urban agriculture's contribution to household food fulfillment and income. The findings showed an insignificant 9% contribution to food fulfillment and a 41.5% contribution to income. This limited impact was attributed to metropolitan complexities, including restricted land access and increasing commercialization.

Workshops critically experimented with the possibilities and challenges of blockchain as an infrastructure for food abundance and reparative work, using fictional scenarios set in a London transformed into a city farm by 2025. This experimentation suggested that blockchain presents challenges to such restorative and sustainable work. For participants, reparation involved working in the aftermath of social and environmental collapse to bring into being more-than-human-value systems that radically decentered human knowledge and experience.
