A one-month community-service program in Gulon RT 01 RW 19, Kelurahan Jebres, Surakarta, Indonesia, addressed underused home-yard land and limited vegetable-cultivation knowledge by delivering outreach, hands-on training and mentoring to 15 participants in growing bird's-eye chili using simple growing media. Participation, understanding and skills in productive use of yard land increased; most participants applied the techniques independently and reported healthy plant growth with harvest potential, and the activity was reported to reduce household spending and raise awareness of food security.

A Photovoice study in Addis Ababa, Ethiopia, had women of reproductive age photograph challenges to healthy diets for themselves and their children under five, then discussed the images in five focus groups (n=31 women) split by lower and higher socioeconomic status, analyzed with hybrid deductive-inductive thematic coding. Financial and physical barriers to accessing healthy food, time constraints and perceived poor food safety were major shared contributors to poor diets; lower-SES women also cited limited nutrition knowledge, inadequate family support and poor home food environments, while higher-SES women cited unhealthy food preferences combined with easy access to and aggressive promotion of unhealthy foods. Proposed solutions included government-level measures (job creation, nutrition education, affordable healthy food, household infrastructure investment, expanded childcare, restrictions on unhealthy-food promotion) and societal-level measures (gender equality, community-based loan schemes, and support for urban agriculture).

A book chapter addresses rising food and nutritional insecurity from rapid urbanization in Sub-Saharan Africa, South Asia and elsewhere, noting that 55% of the world population currently lives in cities, projected to reach 70% by 2050. It states that as much as 10-20% of food consumed could be grown within city limits, but that careful planning is needed to reduce risks from soil contamination, plastic pollution, and reuse of grey/black water and city-waste compost. It identifies rooftop gardens, multistory glass buildings, and soil-less methods such as aquaculture, hydroponics and aeroponics as modern forms of urban agriculture, and discusses barriers including land tenure and research priorities for scaling up.

A review article addresses how, in Sub-Saharan Africa (SSA) where malaria transmission is increasing in urban and peri-urban areas due to rapid urbanization and inadequate infrastructure, urban agriculture — a vital livelihood strategy in peri-urban SSA — often intersects with poor water management practices, creating favorable breeding grounds for malaria vectors, particularly Anopheles mosquitoes. It examines the complex relationship between urban agriculture, water management and mosquito breeding in peri-urban areas, including how irrigation systems, water storage and waste management contribute to malaria transmission, and discusses the implications for malaria control. It also reviews emerging technologies such as remote sensing, GIS and mobile health platforms that can enhance mosquito surveillance and community involvement, and calls for a multi-sectoral approach spanning urban planning, vector control and community-based interventions, along with sustainable urban agricultural practices to mitigate malaria risks in SSA.

A comparative cross-sectional study of 315 urban vegetable-farming households along the Akaki Rivers in Ethiopia used structured questionnaires, multivariable logistic regression, multilevel mixed-effects models and bootstrapped mediation analysis. Two-week diarrhea prevalence was 11.4% (36/315) among children and 8.7% among adults; in this cross-sectional design, which cannot establish causality, wastewater irrigation was associated with more than double the odds of diarrhea (AOR=2.10, 95% CI 1.30-3.40), frequent contact with irrigation water with 80% higher odds (AOR=1.80), and regular raw-vegetable consumption with 60% higher odds (AOR=1.60). Handwashing with soap (57% risk reduction), bathing after farm work (41% reduction) and household water treatment (45% reduction, AOR=0.55) were protective, clustering by irrigation site was modest (ICC about 6%), and hygiene practices mediated 28% of the exposure-outcome relationship.

Using four pooled annual cross-sectional surveys of Zimbabwean urban households from 2019 to 2023, this analysis applied an endogenous switching model with count outcome (ESMC), with propensity score matching as a secondary robustness check, to estimate the effect of urban agriculture on household dietary diversity. Large households, and those headed by women, older heads, or married couples living together, were more likely to practice urban agriculture; practicing urban agriculture increased the likelihood of greater dietary diversity, but this effect held only for the sub-population of households that did not receive support from rural relatives.

Focused on the UPZ 96 Lourdes area of the Santa Fe Tercera locality in Bogota, Colombia, this paper reports on an initiative that treats urban agriculture as a tool for building sustainable food systems. From an environmental standpoint, it advances a process of training and knowledge exchange using an agroecological approach in private spaces, generating self-supply and self-consumption of agricultural products and using household spaces to plant and harvest organic food free of fungicides that compromise food safety, aiming to prevent declines in quality of life and health problems for consumers. Drawing on a political ecology perspective, the initiative seeks policy directions and direct social action to improve the quality of food consumed in daily diets, prioritizing responsible environmental management and the practice and production of organic agricultural food in urban spaces — promoting healthy eating habits while culturally preserving knowledge exchange and ancestral planting, harvesting and consumption practices in a country whose historical character has been agricultural, and aiming to guarantee food sovereignty.

The Community Cultivation program, a grant proposal project focused on Hays, Kansas, in the United States, sets out a plan for how a community garden could improve access to healthy food in rural areas. Guided by the question of how community-based food initiatives can reduce nutrition-related disparities, the proposal responds to the HaysMed Community Health Needs Assessment, which identifies nutrition and fresh produce access as critical concerns for Ellis County. With an emphasis on food-insecure and low-income individuals, the planned garden aims to reduce health disparities tied to socioeconomic status and strengthen community connections by building gardening and cooking skills. It proposes a multi-phase implementation plan involving collaboration with sustainable landscapers, development of gardening infrastructure, and educational classes, with visitor logs and participant surveys planned to track access to fresh produce, garden usage and skills applied; data collection and analysis are planned to continue throughout implementation.

Against the background of children's gradually weakening connection to nature amid spreading urban lifestyles and digitalization, this paper presents the concept of "accessible nature," which places direct, local experience of nature at the center of environmental education. The described program, "The World of Our Garden" (Kertünk világa), uses urban gardens as learning environments and offers modular activities grounded in experiential and inquiry-based learning. Through observation and hands-on activities, students gain insight into natural processes while developing scientific thinking, an emotional connection to nature, and cooperative skills. Using examples, the paper shows how a schoolyard or community garden in an urban setting can become a complex, motivating learning space for sustainability education.

One in eight South Dakota residents faces food insecurity, which has been linked to higher prevalence of chronic diseases such as heart disease and diabetes. Against this backdrop, this study conducted a preliminary process and impact evaluation of Dakota Food Rx, a pilot community-supported agriculture (CSA) produce prescription (PRx) program in the Northern Black Hills of South Dakota. Healthcare providers (Prescribers) referred low-income and/or food-insecure adults with diet-related chronic disease (Patients) to receive weekly produce boxes from a local specialty producer (Grower); evaluation measures included patient pre-post surveys and key informant interviews with Prescribers, Growers and Patients. From June to November 2024, 30 patients participated, receiving 434 produce boxes (mean 14.5 per patient) valued at over $14,000. Ten pre-surveys and eight post-surveys were completed (seven pre-only, five post-only, three both), along with nine interviews. Overall program satisfaction was high, and patients responding at post-test reported higher food security and sense of community than at pre-test. Thematic analysis of the interviews indicated patients improved their diet, food access and overall health, and that relationships were built among program participants; however, Prescribers, Growers and Patients all reported having to adapt to the program, with future considerations including increased communication, improved workflow, and additional resources.

A field-based comparative study in Saharanpur district, Uttar Pradesh, India, compared soil properties, the growth response of Indian mustard (Brassica juncea L. Czern.), and tissue accumulation of cadmium, chromium, copper, iron, manganese and zinc under irrigation with paper mill effluent (PME) versus borewell water as a control. PME irrigation significantly raised soil pH (8.79), electrical conductivity (4.73 dS/cm), organic matter (3.94%) and all six heavy metals (p<0.001); vegetative growth increased, but heavy metal accumulation was pronounced in roots, with bioaccumulation factors for iron and manganese exceeding the hyperaccumulation threshold and root enrichment factors reaching 226.50 for copper and 40.51 for chromium. Dietary risk modeling found that the health risk index from chromium in leaves exceeded the safety threshold in children (HRI=1.05) and approached risk levels for cadmium and chromium in adults, whereas the borewell-irrigated control soil remained within safe agricultural ranges, marking a clear contrast with the contaminated PME-irrigated soil.

A study of lead, cadmium and copper in urban agricultural systems in three industrial-area Nigerian cities (Owerri, Aba and Port Harcourt), assessing spatial distribution, bioaccumulation and health risks using both deterministic and stochastic (Monte Carlo) approaches. Atomic absorption spectrophotometry found soil concentrations following Pb > Cu > Cd in Owerri and Port Harcourt but Pb > Cd > Cu in Aba, while fish and vegetables followed Pb > Cd > Cu at all three sites. The deterministic assessment found cadmium's incremental lifetime cancer risk exceeded the US EPA acceptable threshold of 1×10⁻⁶ at every site for every sample examined, identifying cadmium as the metal of greatest concern.

A pilot study testing whether a multicomponent school garden and nutrition education intervention increases actual school lunch consumption. Students in grades 1–5 from matched pairs of public schools (one high-poverty and one low-poverty intervention school, each paired with a comparison school) were observed with the System of Observational Cafeteria Assessment of Foods Eaten over 13 days across 28 lunch periods, with consumption defined as the percentage of each entrée and side salad eaten. Students at intervention schools consumed 47.5% of the entrée and 44.1% of the entrée plus side salad, against 34.5% and 31.2% at comparison schools; adjusted models showed 0.13 (P = 0.006) and 0.11 (P = 0.01) more portion units consumed, with no significant treatment-by-pair interactions. The authors conclude that a cluster-randomised trial is warranted.

A quasi-experimental pilot study with 3-month follow-up assessed a food pantry-led, subsidized community-supported agriculture (CSA) program called Farm Share in New York City. Farm Share provided biweekly bags of about 25 pounds of fresh produce at $5 per bag; control participants were recruited from a comparable food pantry without CSA (Farm Share n=54, control n=69), predominantly Hispanic/Latino, Black or African American, foreign-born, female and with a high school education or lower. Retention at follow-up was 65.0% (Farm Share n=33, control n=47). Skin carotenoids increased by 12 points in the Farm Share group relative to control, adjusted for smoking status, age, sex and birthplace (P=0.005), but total Healthy Eating Index (HEI) declined by 6.3 points (P=0.031) and the saturated fats HEI component declined by 1.1 point (P=0.027) in the Farm Share group. Improvements in fruit and vegetable intake (P=0.25) and food security (P=0.16) were not statistically significant.

A PRISMA-based review synthesising peer-reviewed articles published between 2015 and 2025 on the status, challenges and opportunities of home and urban vegetable gardening in Ethiopia. It frames urban and home-based gardening as a practical response to food insecurity, malnutrition and environmental degradation in rapidly urbanising areas where the search for better opportunities has driven rising unemployment and limited access to nutritious, affordable food. The barriers it identifies — limited access to land and clean water, gendered barriers to women, limited technical knowledge, inadequate extension services and weak institutional support — all hinder production and sustainability. It further notes that widespread irrigation with untreated wastewater poses significant health and environmental risks through heavy-metal contamination and soil-transmitted infectious disease. Opportunities such as using vacant urban lots, promoting vertical gardening and supporting local seed production remain untapped; government support for urban gardening has grown recently but its implementation remains inconsistent. The review also identifies a significant geographical gap within the existing literature.

A shotgun metagenomic study motivated by how little is known about the microbial communities and antimicrobial resistance (AMR) profiles of rooftop and surface garden soils in Bangladesh, and their potential role as reservoirs and disseminators of AMR, despite the growing expansion of urban agriculture. Twenty-seven soil samples were sequenced — 7 from Dhaka rooftop gardens, 6 from Dhaka surface gardens, 8 from Gazipur rooftop gardens and 6 from Gazipur surface gardens. The work identified 88 antibiotic resistance genes (ARGs), of which 19 (21.6%) were shared across all sites, and found significant differences in resistome composition by garden type (p = 0.04). Rooftop soils harboured more ARGs (Dhaka 50, Gazipur 48) than surface soils (Dhaka 40, Gazipur 41) and were dominated by glycopeptide resistance genes, collectively 62.43-74.07% of ARGs; rooftop soils were also enriched in efflux pumps (adeF, 45.21% of rooftop ARGs) and the ribosomal-protection oxazolidinone resistance gene O23S (62.13% in Gazipur rooftops). Surface soils instead featured more genes mediating antibiotic inactivation, such as CATA (11.64% in Dhaka surface gardens) and fosBx1 (5.94% of surface ARGs).

A qualitative study of a home gardening intervention in Siaya county, rural Kenya, undertaken because home gardens are promoted as a climate change adaptation strategy in sub-Saharan Africa but the lived experience of them is less documented. Between September and November 2023 the authors ran two focus group discussions with stakeholders (n = 5) and implementers (n = 8), plus 30 in-depth interviews with male (n = 5) and female (n = 25) beneficiaries, using purposive sampling and semi-structured guides; data were transcribed verbatim and analysed by inductive content analysis mapped along the proposed impact pathways. Participants articulated a good understanding of the trainings and valued them as an occasion for knowledge exchange, and the adoption of tailored garden structures, organic gardening and food preservation created feelings of fulfilment, women's empowerment and family peace. Challenges included water scarcity, ineffective pesticides and long distances between beneficiary households. Perceived benefits were increased income, cost savings and increased dietary diversity.

Polycyclic aromatic hydrocarbons (PAHs) persist in soil and resist common recovery strategies, which matters for urban agriculture because such sites are highly exposed to varied pollution sources — and because that exposure shapes how urban growing is perceived. This study examined the fungi already present in polluted soil intended for urban agriculture, aiming to build an active microbial consortium able to transform the pollutants and lower site toxicity. The mycobiota was dominated by Ascomycota; among 28 isolated taxa across 16 genera, Aspergillus, Scedosporium, Trichoderma and Fusarium were the most abundant. Isolates differed markedly, between and within species, in their ability to grow in the presence of low- and high-molecular-weight PAHs, and some produced biosurfactants. Combining this with the ability to grow on carriers, six fungi were selected for in situ soil remediation, and biostimulation was compared with bioaugmentation using strains in co-culture. The best results came from a consortium that also showed high tolerance to high-molecular-weight PAHs. Chronic ecotoxicity testing showed no effect on Eisenia fetida except under biostimulation, which produced a 44 per cent decrease in toxicity. A mix of millet and canary seeds worked as an efficient fungal carrier.

This Wikipedia article covers Robert Hart (1913-2000), a British horticulturist credited as the pioneer of temperate-climate forest gardening. He converted a 0.12-acre (500 sqm) orchard at his Shropshire home into a model forest garden structured in seven layers (canopy, low-tree, shrub, herbaceous, ground-cover, rhizosphere, and vertical/climber). The article also notes he followed a roughly 90% raw vegan diet, citing the Hippocratic maxim to 'let food be thy medicine.'

This official U.S. EPA page on 'The Effects' of nutrient pollution explains that excess nitrogen and phosphorus entering air and water cause algal blooms, degrading water quality and reducing dissolved oxygen. It states cyanobacteria can release toxins that sicken people and animals via contact, drinking water, or contaminated seafood, that nitrates in drinking water pose risks to infants, and that excess airborne nitrogen contributes to ammonia and ozone formation. The page itself contains no specific numeric statistics on economic damages or dead-zone area.
