A study of urban gardens in Vienna, Austria, building on a previous study of eleven gardens in the city that found elevated lead (Pb) levels in some soil and plant samples. This work examined the elemental composition of soil and plants from two of the affected gardens one year after compost amendment. ICP-MS analysis of tomato fruit skin, pulp and seeds showed only minor variations in elemental composition unlikely to affect food safety, whereas radishes showed a tendency toward contaminant accumulation in root tips and leaves. Washing lettuce significantly reduced levels of potentially toxic elements including Be, Al, V, Ni, Ga and Tl, underscoring the importance of washing garden produce before consumption; compost amendment was associated with reduced Zn, Cd and Pb levels in radish bulbs. Lead isotope ratios in soil and spinach leaf samples from the earlier study, assessed by MC-ICP-MS, showed a direct linkage between the Pb isotopic signatures in soil and spinach leaves, supporting their use as tracers of Pb sources in the environment.

Using soil data from ten peri-urban case farms near Oslo and Bergen, Norway, this study estimated how quickly potentially toxic element (PTE) concentrations would rise in soil under intensive application of compost or digestate from food waste, composted garden waste, or horse and poultry manure applied annually to meet a theoretical carrot crop's nitrogen, phosphorus and potassium demand. Under this intensive fertilization scenario, Norwegian soil quality limits for PTEs would be reached within 20-85 years, faster in soils with more organic matter, with limits reached first for copper and zinc, both essential micronutrients. The urban waste-based fertilizers were also found to be poorly balanced in macronutrients, with rates covering potassium demand leading to high phosphorus and nitrogen surpluses. The study concludes Norway's PTE regulations are stricter than the EU's and do not support recycling organic matter and nutrients from urban waste.

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.

A review examines the dynamics of antibiotic resistance (AR) in urban soils, cataloguing multiple sources that introduce antibiotics into urban soil, including domestic wastewater, industrial effluent and urban agricultural practices, as well as microplastics and domestic animal excrement. It states that the selective pressure from these anthropogenic sources promotes the proliferation of antibiotic-resistant bacteria through horizontal gene transfer among soil microorganisms, poses a significant public health threat by potentially transferring resistance genes to human pathogens via direct contact, food consumption and water ingestion, and disrupts microbial community dynamics in ways that affect soil fertility, plant growth and overall environmental quality.

This study assessed heavy metal contamination in 96 surface sediment samples collected from urban, agricultural, and forested areas of the Bug River catchment in Poland between July 2018 and 2020, measuring metals (Zn, Pb, Cr, Ni, Cu, Fe, Mn, Cd) by atomic absorption spectroscopy and applying the geoaccumulation index (Igeo), contamination factor (CF), and pollution load index (PLI). Urban sediments showed significantly higher heavy metal concentrations than agricultural or forested areas, with cadmium reaching up to 2.5 mg/kg; the average Igeo for cadmium was 0.24 in agricultural areas and 0.15 in urban areas, while the highest PLI values, reaching a maximum of 0.33, occurred in urban areas, and statistical analysis showed both urban emissions and agricultural activities significantly influenced heavy metal presence in the sediments.

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 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 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 Lahore, Pakistan, investigated trace element (TE) contamination in water, soil, fodder, and buffalo milk due to the use of untreated wastewater from the Hudiara drain for agriculture. Samples collected along the drain showed that TE contamination, including Cd, Cu, Ni, and Zn, increased from upstream to downstream sites. Concentrations of these elements in water, soil, fodder, and milk surpassed permissible limits, indicating a significant transferability risk up the food chain and high Hazard Index values for irrigation water, fodder, and milk.

A cluster randomized controlled trial in rural Nepal (n=680 school children aged 9-13 across 30 schools) investigated whether an integrated school and home garden intervention improved hemoglobin levels and reduced anemia. The intervention did not lead to a direct significant reduction in anemia, as nutritional improvements were not strong enough to impact hemoglobin levels. However, the program indirectly improved hemoglobin levels for children under 12 by increasing good food and hygiene practices at home, particularly for girls, young children, and those with literate caregivers.

COULIBALY Moussa · International Journal of Advanced Research · Côte d'Ivoire (Korhogo)

This study in Korhogo, Côte d'Ivoire, surveyed 81 farmers to assess the impact of urban agriculture on food production and farmer health. It found that urban agriculture, predominantly practiced by women (85.19%) with no formal education (71.61%), involves the use of chemical fertilizers and pesticides with non-adherence to application intervals. A significant portion of farmers (59.26%) discard chemical packaging in the environment. Despite contributing to empowerment, this practice exposes farmers to health problems including fatigue (53.09%), injuries (25.92%), skin burns (11.11%), dry coughs/colds (32.10%), and diarrheal diseases (19.75%).

This phenomenological study investigated the motivations of non-traditional urban agriculture students of color to remain in agriculture. Findings suggest that while systematic instruction in agricultural sciences and positive local youth organization experiences contribute to a favorable perception of agriculture, they do not necessarily lead to a career preference for agriculture among these students. Furthermore, urban students of color perceived that the FFA Organization above the school level is not inclusive of them.

This overview identified eight ecosystem services generally attributed to urban agriculture, including food production, microclimate regulation, stormwater retention, and social-cultural values. However, the study found that quantitative evidence for many of these ecosystem services, especially intangible ones, is scarce. It suggests that while urban agriculture could be integral to green infrastructure, further consideration is needed for types, technology, management, and potential tradeoffs.

This study assessed human health risks from contact with contaminated soil and consumption of plants grown in contaminated soils in allotment gardens and farmlands located in areas affected by Zn-Pb and steel industries and hard coal mining. Using US EPA methodology and pseudo-total concentrations of Potentially Toxic Elements (PTEs) in soil and plant samples, estimated daily intake and non-carcinogenic and carcinogenic health risks were analyzed for recreational and residential exposure scenarios. Findings indicated that the proportion of different exposure pathways in total health risk decreased in the order: intake of contaminated vegetables > accidental soil ingestion > dermal contact > inhalation of contaminated soil particles, and children are more exposed to toxic effects of PTEs than seniors and economically active adults.

This study compared bioactive compounds in pomegranate genotypes from a continental region (Sremski Karlovci, Serbia) and a Mediterranean urban region (Bar, Montenegro). Analysis of phenolics, tannins, flavonoids, proanthocyanidins, pigments, vitamin C, acidity, pH, and sugars, along with DPPH and ABTS antioxidant tests, revealed that pomegranates grown in the continental area had significantly higher amounts of biochemically active compounds than those from the Mediterranean urban region. This suggests adaptation to continental conditions, with continental samples showing greater antioxidant potential and proanthocyanidins content.
