Johan Pottier · Africa · Rwanda

This article explores the themes of knowledge, ignorance, and power in the context of a Rwandan development project, demonstrating how ignorance is generated through agricultural extension. It argues that agronomic services rely on power structures reminiscent of social inequality, and assesses whether the project-induced creation of ignorance leads to the displacement of local knowledge and the adoption of new methods.

· 法令（e-Gov法令検索・401AC0000000058） · Japan

The 1989 special-measures act exempting small, short-term, non-commercial farmland lettings (the allotment-garden pattern: under 10 ares, up to five years) from Farmland Act transfer permission. It let local governments, agricultural cooperatives and others run citizen farms, forming the legal foundation of Japan's allotment gardens.

Rakodi C. · The Journal of Modern African Studies · Zambia (Lusaka)

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.

François Villien · Cahiers d Outre-Mer · Central African Republic (Bangui)

Bangui, Central African Republic, exhibits significant inter-urban agricultural activity, reflecting population poverty. This agriculture is categorized as "inter-domain," practiced within concessions near houses, or "extra-domain," conducted outside family domains. Inter-domain agriculture includes small "jardin de case" (hut gardens) for diverse foodstuffs and larger "champ de case" (hut fields) for single crops like manioc, now also serving as income sources. Extra-domain agriculture utilizes empty land in peripheral districts for food, income, or temporary pioneer front crops, sometimes becoming permanent and hindering urban expansion. Urban agriculture is considered essential for the survival of many family units and for integrating the city into its food supply space.

C J van Vuuren · Development Southern Africa · South Africa

This article discusses the nature and functioning of community gardens in Ciskei, KwaZulu, and KwaNdebele, South Africa. It found that these community gardens are indigenous, acceptable to the local people, and are actively producing food, also demonstrating significant local expertise that should be recognized and developed by agencies. The article argues that these units have often been neglected by agricultural officers.

Chiaki Negoro, Atsushi Tunekawa · Journal of the City Planning Institute of Japan · Japan

This paper examines the public perception of urban agricultural land as valuable open space in urban fringe areas. The study found that urban agricultural lands are considered valuable "green" spaces, with orchards (mainly persimmon trees) and farms being particularly highly evaluated. These positive perceptions were observed in both agricultural and nearby residential areas.

M. 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.

Youko Yokokawa, 洋子 横川 · Institutional Repositories DataBase (IRDB) · Japan

This 1988 report describes changes in Tokyo's agricultural structure driven by urbanization alongside the state of urban residents' diets. Labor and farmland shifted from Tokyo's special wards to the Tama area, where intensive cultivation of fresh produce such as vegetables was concentrated, while in mountainous districts agriculture was combined with forestry. Cultivated land had shrunk by about 60% over the preceding 25 years, and the number of full-time farm households had fallen by 70%, while part-time farm households roughly doubled. Taking advantage of proximity to a large consumer market, 118 vegetable species were cultivated, with production of daikon radish, spinach, and komatsuna increasing year on year. Self-sufficiency rates for key products were 12.7% for vegetables, 7.2% for milk, 3.4% for eggs, and 2.4% for meat. In the urban diet, average nutrient requirements were largely met, though calcium was somewhat lacking and vitamins B1 and C slightly insufficient. Intake of beans, seafood, and vegetables was low by food group, and average daily salt intake was 13.4g, above the 10g target. Eating out and skipping meals were relatively uncommon overall, but skipping meals — especially breakfast — was more common among high-school-age students and older.

Williams, 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.

Yuzo 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.

和彦 武内, 洋一 松木 · Institutional Repositories DataBase (IRDB) · Japan

The available abstract for this 1987 Japanese paper consists only of a repository description (the University of Tokyo's institutional repository, UTokyo Repository) rather than the paper's content, so no findings, methods, or data about farmland's green-space value or the role of urban agriculture can be reported from it.

Christine Furedy · Water Science & Technology · India

This 1986 paper argues that sociocultural factors — the attitudes and behaviors of both planners/administrators and service recipients — need more attention in waste disposal and treatment policy in developing countries, drawing examples from Calcutta and Lucknow, India, and contending that more research on informal waste reuse practices, including in aquaculture and urban agriculture, could inform how reuse is integrated into community waste disposal systems, which would require changes in officials' attitudes toward established informal practices.

Michael S. Jamison · Sociological Quarterly · Global

This study assesses the organizational cultures of collectives and bureaucracies within the urban gardening movement, finding serious underlying differences despite government assistance. Although government agencies provided resources and established projects, collectives and bureaucracies interpreted the urban gardening experience differently. This divergence in understanding the benefits and structuring the experience reveals a source of potential bureaucratic/collectivist conflict.

Allan Bunch · Global Knowledge, Memory and Communication · Global

A short 1984 review (Global Knowledge, Memory and Communication) of the third edition of the "Community festivals handbook," published by Community Projects Foundation. The review describes the handbook as a practical guide to organizing local, day-to-multi-day community festivals, covering committees, publicity, legal and site-management aspects, and notes it is also relevant to other community-based activities such as barbecues, fundraising, adventure playgrounds, or "setting up a city farm." The review does not report any study, data, or findings specific to urban farming.

H. 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.

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.

W.P. Holtz, H.J. Mooy · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · United States

A 1982 final report presenting the design and construction of a community greenhouse in Newark, New Jersey, United States. It includes photographs and drawings of the greenhouse construction along with a demonstration of budgeting information.

Earle Barnhart · Birkhäuser Basel eBooks · United States

This paper argues that producing food within a forest ecosystem through careful cultivation of tree crops on hilly, marginal land is a successful and sustainable strategy for conserving soil and nutrients, and holds potential for the northeastern United States, where natural vegetation is predominantly steep, hilly forest unsuited to normal food production. Drawing on forest farming development at the New Alchemy Institute on Cape Cod, Massachusetts, it discusses concepts of ecology, energy use and erosion control in agricultural ecosystems.

Abalimi Bezekhaya · Abalimi Bezekhaya · South Africa

The official site of Abalimi Bezekhaya, a non-profit founded in 1982 that provides urban agriculture training, affordable resources, irrigation and soil-building support, and market access in Khayelitsha and Nyanga, Cape Town. It states its Harvest of Hope programme generated R16 million in sales between 2008 and 2019, of which R10 million went directly to about 245 farmers (supporting 1,225 dependants) across roughly 70 gardens.

· Nutrition & Food Science · Global

The Institute of Biology held a symposium to assess the value of vegetables for feeding people and livestock. The symposium considered the energy, labor, and monetary inputs required for vegetable production across various scales, from allotments to large market gardens. Discussions also included the role of traditional and unconventional animal species within vegetable growing systems.

Ledogar Rj · PubMed · Zambia (Lusaka)

In 1978, a pilot project was initiated in Lusaka, Zambia, by UNICEF and The American Friends Service Committee to expand urban agriculture. This project aims to establish kitchen gardens on residential plots, cultivate road reserves and green belts, utilize idle land during the rainy season, raise small livestock, promote cooperative cultivation of small holdings in the urban periphery by low-income residents, and eventually resettle some urban residents on farms. The goal is for the service to be self-supporting by 1980.

Howard 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.

M. A. Latheef, R.D. Irwin · The Canadian Entomologist · United States

A paper on field experiments conducted in southside Virginia, United States, sought to quantify the effect of companion plants (repellent herbs) on major lepidopteran pests of cabbage. It cites an estimated 33 million home and community gardens grown in the United States during 1976 and 1977 as context, noting that claims about companionate planting's protective effects made by organic growers had little field evidence to substantiate them. The abstract does not report the experiment's specific results.

Bundesverfassungsgericht · Bundesverfassungsgericht (DFR, Universität Bern) · Germany

The First Senate judgment of the Federal Constitutional Court of 12 June 1979 (docket 1 BvL 19/76). It held that the combination of a blanket bar on termination, narrowly enumerated grounds, mandatory administrative approval and price control under the 1944 protection ordinance and the 1969 amending act was incompatible with the property guarantee of Article 14 of the Basic Law as it applied to private landlords. Section 1(3) of the 1944 ordinance and section 2(2) of the 1969 act were declared void for breaching rule-of-law principles. The court reasoned that allotments had shifted from subsistence necessity to recreational use, weakening the social justification for restrictions of that breadth.
