Metals in urban gardens ‐ effect of lime and sludge
1995James R. Preer, Ahmed N. Abdi, Harkewal S. Sekhon, George B. Murchison · Journal of Environmental Science and Health Part A Environmental Science and Engineering and Toxicology · Global
This study investigated cadmium (Cd) and zinc (Zn) concentrations in vegetables grown in community gardens on different urban soils. Vegetables from a low-pH urban soil without contamination history showed higher Cd and Zn levels than those from a reclaimed landfill with digested sewage sludge, and also higher than a low-metal, neutral-pH site. Liming on the low-pH site reduced Cd and Zn concentrations in beet, lettuce, radish, and Swiss chard leaves, reaching background levels after four years. The findings indicate that soil pH is more important than total soil Cd and Zn in determining vegetable metal availability.
Contamination & food safetyHealthCommunityOrganic cycleUrban horticulture: a part of the biodiversity picture
1994H. B. Tukey · Cambridge University Press eBooks · Global
This paper defines urban horticulture as the functional use of plants to improve urban environments. It states that urban horticulture contributes to screening views, food production, reducing noise and air pollution, ameliorating urban climates, and improving human well-being. The abstract notes that information on city plants often comes from observations and anecdotes, and that strategies from commercial agriculture do not always apply well to urban horticulture.

1993Lee M · PubMed · Ethiopia
In Ethiopia, urban agriculture faces significant challenges due to government disapproval of public land use for farming and difficulty in obtaining credit. A 1983 survey in Addis Ababa found that 17% of 1352 households produced their own food on less than 25 sq. meters, with 90% of non-farmers citing lack of land. Despite urban agricultural cooperatives demonstrating 70% higher member income, their lack of government legalization prevents access to loans for productivity improvement.

A field-based study of Zambian urban settlements in the 1970s-1980s, finding that urban cultivation serves as a vital survival strategy for low-income households and warrants integration into urban development planning.

1988Kasipathy Kailasapathy · Ecology of Food and Nutrition · Sri Lanka
This study developed a model school garden (28m²) in Sri Lanka to provide part of the nutritional requirements for school children. The garden produced an average daily yield of 813g of vegetables, supplying significant percentages of a 10-12 year old child's recommended daily intake, including 115% of calcium, 151% of iron, 557% of vitamin A, and 1222% of vitamin C.

1988M. Krelowska‐Kulas · Food / Nahrung · Poland (Kraków)
An investigation using atomic absorption spectroscopy in Kraków, Poland, found that vegetables from urban allotment gardens had average levels of lead, cadmium, copper, zinc, and iron several times higher than control samples from farms 100 km away. In some cases, maximum levels of certain elements approached the admissible limit. However, average levels of lead and cadmium in pigs and cattle showed no reason for objection.
Contamination & food safetyHealthCommunityCadmium and lead in soils and crops from allotment gardens in the Netherlands.
1987P. van Lune · Netherlands Journal of Agricultural Science · Netherlands
A study analyzed cadmium (Cd) and lead (Pb) in soils and crops from 57 allotment gardens in potentially contaminated areas of the Netherlands. The median Cd and Pb concentrations in the soil samples were found to be higher than those in soils used for arable farming and horticulture. However, Cd and Pb concentrations in the crops themselves were normal.

1987Williams, Patrick Neal. · K-State Research Exchange (Kansas State University) · United States (Manhattan, Kansas)
A five-month study of children gardening in the Manhattan Community Garden, Manhattan, Kansas, investigated differences in self-esteem, horticultural knowledge, and garden quality. Children without other siblings gardening showed higher self-esteem, gained more horticultural knowledge, and had better appearing gardens than children with other siblings gardening.
Food educationCommunityHealthA Comparative Study on the Types of Community Farms by Urban Residents
1987Yuzo Uchida · Journal of the City Planning Institute of Japan · Japan
This study aims to clarify the situation and types of community farms in Japan, their usage patterns, and their impact on the lives of urban residents. It notes the strong demand for community farms for cultivating vegetables and flowers among urban residents. Various types of community farms exist, including allotment gardens, Japanese Kleingartens, self-supplying community farms, and full-scale orchards in the countryside.
CommunityEconomicsHealthUrban Horticulture: Horticulture for Populated Areas1
1983H. B. Tukey · HortScience · Global
Urban horticulture is defined as a scientific field focused on the functional uses of plants to maintain and improve urban environments. These functional uses extend beyond aesthetics to include screening against wind and views, influencing climate, reducing noise, combating air pollution, providing food, and enhancing human well-being in densely populated areas. The audience for urban horticulture includes landscape professionals, plant societies, and amateur horticulturists.

1982Pauline Raphaely · Birkhäuser Basel eBooks · South Africa
Food Gardens Unlimited is an educational project in South Africa that teaches disadvantaged urban populations to grow food in small areas using limited resources. The project provides five-day training courses, step-by-step directions, and subsidized seeds through existing institutions. It aims to deliver physical, emotional, and spiritual benefits to participants.

1979Howard J. Atkinson, Naomi Gibson, Harry C. Evans · Plant Pathology · United Kingdom (Leeds)
A survey of 140 growers across 12 allotment sites around Leeds, UK, identified a wide range of crop pests, with brassicas, potatoes, and carrots being more frequently damaged. Soil samples from 33 plots at 10 established sites and 6 plots at 2 new sites revealed potentially damaging levels of pale potato cyst nematode in 21 and 1 plots, respectively. Widespread overwintering populations of carrot fly larvae and pupae were also found in soil samples from eight sites.
Contamination & food safetyCommunityBiodiversityHealthA study of soil contamination and plant lead uptake in Boston urban gardens
1979T. M. Spittler, William A. Feder · Communications in Soil Science and Plant Analysis · United States
This study demonstrated a serious problem of lead contamination in Boston's urban environment by analyzing about 900 soil samples from backyards, play areas, community gardens, and playgrounds using X-ray fluorescence spectroscopy. An average lead level of 800 ppm was found, traceable to the past widespread use of lead paint. Selected plant species grown in soils with lead levels ranging from 100–2000 ppm showed differing affinities for lead uptake, with fruits taking up less than roots and roots less than tops, indicating positive translocation of lead from soil into plant tissue.
Contamination & food safetyHealthPlants as “Children” in Introductory Child Psychology
1979William E. Roweton · Psychological Reports · Global
This study discussed the instructional advantages of growing vegetable seedlings in an introductory child psychology course. The project drew students' attention to the importance of nutrition in child development, as well as the popularity and practicalities of urban gardening. Additionally, the activity of "raising" plants proved to be a provocative analogy to "rearing" children.
Food educationHealthDIYThe Community Garden: Horticulture for the People1
1973Steven L. Doud, Greg Pagano · HortScience · United States
Many American urban dwellers are rediscovering that gardens can provide inexpensive, high-quality food, recreation, and relaxation. This "green thumb boom" is particularly evident in the emergence of community garden projects in college communities, where students seek to supplement incomes and work with plants. While these projects vary in management philosophy and workload allocation, they share common goals of abundant food production and enjoyment for gardeners.

1971重一朗 浜, 伝 中村 · 年会予稿集 · Cuba
In Cuba, programs such as dietary diversification, food fortification, and supplementation are implemented to address micronutrient deficiencies like iron, vitamin A, and iodine. Urban agriculture is positioned as one strategy to increase dietary diversity by enhancing the availability and consumption of vegetables and fruits. Research in Cuba has shown that vitamin A deficiency is nonexistent in children up to 7 years of age.
