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.

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.

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.

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.

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.

Gary B. Palmer · Anthropological Quarterly · United States

This paper applies Clifford Geertz's theory of involution, defined as social and technological substrategies for resource scarcity, to water development in the Colorado River Basin, United States. It proposes involution, including urban agriculture, as an alternative to competitive expansion, interpreting its regional implications for geothermal, desalinization, and irrigation projects. The study suggests that impacts on regional water allocation and quality from energy development depend on institutional and economic factors.

This study investigated the actual conditions of school gardens at 77 primary schools in Osaka City, Japan. Based on the findings, it designed a model plan for creating school gardens in urban primary schools; the average garden area was 956 sq m, and the average utilization rate (garden area relative to available space) was 37.1% — figures the study characterizes as insufficient both in space and in tree variety for maintaining trees as teaching materials — and it examines how to most effectively use the limited available space given these constraints.

Sam Love · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · Global

This paper discusses contemporary industrial societies' reliance on extensive resource networks and proposes an alternative: moving towards self-sufficient small loop and flow systems. It describes examples of short loop arrangements in urban agriculture and solar energy housing, advocating for decentralization and diversity.

· 法令（e-Gov法令検索・349AC0000000068） · Japan

The 1974 law establishing productive green land districts: farmland inside urbanisation promotion areas keeps farmland-level taxation in exchange for restrictions on construction. The 1991 amendment paired it with residential-level taxation in the three metropolitan areas; the 2017 amendment lowered the size threshold to 300 square metres and created the tokutei (specified) designation.

This chapter is subdivided into three sections concerned with public parks, children's playgrounds, and allotment gardens.

Steven 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.

The 1973 act on conservation and promotion of urban green space, providing green space conservation areas, citizen-green-space contracts and greening districts. The 2017 amendment added the certified citizen green space scheme and explicitly positioned urban farmland as green space, joining farm policy to green-space policy.

E. F. Schumacher · Blond & Briggs · United Kingdom

E.F. Schumacher's 1973 book challenges the mainstream "bigger is better" economic ethos, advocating small, "appropriate" technologies as an alternative. Its four parts cover the modern economy, resources, the developing world, and organization/ownership; in 1995 the Times Literary Supplement named it one of the 100 most influential books since World War II.

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.

Jeff Garmany · The Journal of Modern African Studies · Africa

This article argues that many African countries, in their pursuit of rapid economic development, risk misaligning their strategies and priorities concerning the rural-urban and agricultural-industrial balance. It specifically advocates for increased research attention on traditional food farming, whether for subsistence or cash, which has been neglected despite its crucial and inevitable role in supporting growing populations over the long term.

Natalia Przesmycka, Rafał Strojny · Teka Komisji Architektury Urbanistyki i Studiów Krajobrazowych · Poland (Lublin)

This article examines allotment gardens in downtown Lublin, Poland, from a historical, architectural, and landscape perspective, focusing on the oldest garden, "Nasza Zdobycz nad Bystrzycą." It identifies that city-center allotment gardens are at risk from commercial development and discusses the increasing alienation of owners and progressing devastation of these areas. The study also attempts to explain these issues and suggests design applications for revitalization.

Clifford W. Scherer · Journal of Applied Communications · United States

A 1970 article situates the traditional rural orientation of agricultural extension audiences historically, noting that 66% of the U.S. population was rural when the land-grant colleges were established, and that more than a quarter of the population still lived on farms 52 years later when the Smith-Lever Act created the Cooperative Extension Service. The abstract text provided contains only this historical background and no specific findings about the actual use of radio public service announcements for urban agriculture.

Natália da Silva Lemos, Liza Maria Da Souza de Andrade, Valério Augusto Soares de Medeiros · Paranoá cadernos de arquitetura e urbanismo · Brazil

This research analyzed urban planning challenges in Brazil from the perspective of urban agriculture, examining social policies and legal frameworks including the City Statute (Law 10.257/2001) and Law 6.766/1979. The findings indicate a gap in legal provisions for urban agriculture actions and practices within land use and occupation regulations. The study suggests guidelines for implementation to address this deficiency.
