A study in Quebec City, Canada, interviewed 55 food-insecure households and 59 stakeholders to compare perceptions of food security needs and community programs. While both groups agreed on the need for better financial resources, households reported that food quality and access were neglected, and that existing programs, even combined, were insufficient to meet their needs. Stakeholders, however, largely perceived households as satisfied with programs and believed their primary need was a basic amount of food. The study concluded that community programs alone cannot bring about the social change needed to prevent food insecurity.

Alex Thornton, Etienne Nel · Africanus Journal of Development Studies · South Africa (Peddie)

This study investigated the significance of urban and peri-urban agriculture (UPA) as a livelihoods strategy in Peddie, Eastern Cape province, South Africa, based on a PhD study. The findings indicate that UPA is not as significant or widely practiced as often assumed, despite its potential to address food insecurity and generate income. Its development has been slowed by various structural historical and socioeconomic barriers, limiting its current impact.

Jonathan Kingsley, Mardie Townsend · Urban Policy and Research · Australia (Melbourne)

A small qualitative study of members of the 'Dig In' community garden in Melbourne, Australia, explored the social capital benefits of urban community gardens. The study found that garden membership offers benefits such as increased social cohesion, social support, and social connections. However, these benefits do not necessarily extend beyond the garden setting, especially in the early stages of development.

Emma Lea, Jodi Phillips, Madeleine Ward, Anthony Worsley · Ecology of Food and Nutrition · Australia (Victoria)

This qualitative study interviewed 20 consumers and 12 farmers in Victoria, Australia, to examine their knowledge, perceived benefits, and barriers regarding Community Supported Agriculture (CSA). The study found that knowledge of CSA was limited among both groups. Consumers perceived fresh food as a benefit but cited lack of produce choice as a barrier, while farmers saw financial benefits but were concerned about risk-sharing.

This study, conducted in 2003 by UNISOL REGIONAL and UFRRJ, aimed to develop an organic, condiment, and medicinal garden through social education activities. A socioeconomic survey of the community revealed urgent problems with water scarcity, mosquitoes, and rodents. While two garden beds and 12 planters were built to encourage self-sustaining urban agriculture, the abstract does not explicitly state the success or failure of achieving self-sustainability or addressing the identified community problems beyond the construction itself.

A study of 196 elementary students in McAllen, Texas, compared the academic progress of students participating in a school garden program with those receiving traditional classroom instruction. No statistically significant differences were found in science achievement scores, indicating similar benefits for both groups. However, students receiving traditional math instruction showed more improved math achievement scores compared to those in the garden program.

A 2005 survey in the 'Alamar' organoponic in Havana province, Cuba, observed typical phytoplasma-symptoms of little leaf and witches' broom in all basil (Ocimum basilicum) plants. DNA analysis of leaf samples from 27 symptomatic plants confirmed an association with a 16SrI group phytoplasma (Aster Yellows; 'Candidatus Phytoplasma asteris'). This report from Cuba is the first record of this new disease, for which the name basil little leaf is proposed.

This field survey in the Modder River basin, South Africa, investigated the potential expansion and implications of a rainwater harvesting technique introduced to small-scale farmers. While a rapid spread within home yard sizes was expected, no significant spread to community gardens or beyond was anticipated in the short term. This limitation was attributed to socio-economic constraints, including poverty and a lack of appropriate tools and basic farming skills.

Ching‐Fu Chen, 黃琮聖, 閻淑慧, 蕭玉華, 蔡郁芬 · · Taiwan

This study surveyed 180 participants from five city farms in Taichung, Taiwan, between March and April 2004, to assess service quality, satisfaction, and intentions. While perceived service qualities were generally good, overall satisfaction was rated as "slightly satisfied," and renewal and recommendation intentions were rated as "slightly agreed," indicating significant room for improvement. Service content and management had significant effects on overall satisfaction, management on renewal, and service content on recommendation.

This paper compared the successes and failures of two urban creek restoration programs in California: Temescal Creek (initiated nearly 30 years ago) and White Oak Creek (completed about four years ago). Based on the author's success criteria, the more recent White Oak Creek program achieved significant success, while the earlier Temescal Creek restoration did not reach generally acceptable success levels. This difference is attributed to changes in management and scientific practice over 30 years, including substantial changes in the legal basis for restoration, improved monitoring requirements, and the critical role of properly engineered low flow distribution structures.

Yansui Liu · · China

China's agricultural structure adjustment from 1997 to 2000 focused on comprehensive adjustments of quality, varieties, industrial, and regional structures. While distinctive agriculture increased by 3.1% during this period, the effects of the adjustment varied significantly due to regional comparative advantages. Notably, foodstuff crop seeding areas dropped by 3.97% and foodstuff yield by 6.47% nationally, with visible drops in 22 provinces, leading to a warning that loosening vigilance on food security necessarily leads to a significant drop in China's food security.

Jean-Noël Consalès · Rives méditerranéennes/Rives méditerranéennes · Europe

This study examines allotment gardens in Marseille, Genoa, and Barcelona and finds that, although urban agriculture is potentially at stake in these cities, allotments struggle to establish themselves within complex urban contexts. Their actual function appears limited: their social role is often overestimated, while their environmental and landscape significance remains largely neglected.

Sigrid Stagl, Sabine O’Hara · International Journal of Agricultural Resources Governance and Ecology · United States (New York City)

This study examined whether Community Supported Agriculture (CSA) groups are a broadly accepted or limited alternative food system, based on a household survey in two distinct socio-economic neighborhoods in upstate New York. The survey found that approximately 25% of respondents expressed interest in becoming CSA members, with similar interest levels in both wealthier and low-income areas. However, several factors preventing food demand through CSAs were identified, indicating that these barriers would need to be addressed for expansion.

Maurizio Tiepolo · PORTO Publications Open Repository TOrino (Politecnico di Torino) · Niger

This paper investigates whether urbanization in Niamey, Niger, generates or aggravates urban food insecurity by examining agro-pastoral production, food demand, and buying power. It found that Niamey's high rate of urban growth has increased food insecurity for its inhabitants. This insecurity is attributed to low productivity of peri-urban agriculture, insufficient food influxes, rising prices, extreme poverty, and a nutrient-poor diet, with current measures failing to address root causes like land tenure uncertainty.

Rachel Slater · Development Southern Africa · South Africa

This study examined urban agriculture (UA) in Cape Town, South Africa, focusing on its contribution to low-income households. It found that UA's contribution to income generation and expenditure substitution is limited. However, UA is important to women in low-income households in ways less directly related to monetary gain, being used for empowerment, establishing social networks, symbolizing a sense of security, and encouraging community development.

Candan Kuş · · Turkey (Ankara)

A study in Yenimahalle District, Ankara, evaluating multiple schools including 80 primary schools, assessed the importance of school gardens and their place within the urban open-green space system. The findings revealed that many school gardens were unsuitable for use by teachers and students, being narrow, containing only ceremonial areas and a few plants, and lacking sufficient furnishing elements. It was also observed that additional buildings further narrowed school gardens, and insufficient attention was given to recreation areas, sports areas, and green spaces.

Raúl Ortíz, Celia Patricia Vera, Antonio Leyva · DOAJ (DOAJ: Directory of Open Access Journals) · Cuba

A diagnostic study was conducted on the conditions of urban gardens, their producers, and families in 20 gardens across five localities in the "Boyeros" and "Arroyo Naranjo" municipalities of Havana, Cuba, between December 1998 and March 1999. While the garden agroecosystems showed satisfactory biodiversity, general knowledge of biological technologies in sustainable urban agriculture remained relatively low. None of the surveyed plot owners consciously knew or used vermiculture, pisciculture, biofertilizers, biopesticides, or biostimulants, and almost half did not consciously use crop rotation.

This study evaluated the "Nutrition in the Garden" program's effect on students' attitudes and behaviors regarding fruit and vegetables. While students' attitudes towards vegetables and fruit/vegetable snacks became significantly more positive after gardening, no differences were detected in attitudes towards fruit. Crucially, students' fruit and vegetable consumption did not significantly improve, remaining at an average of 2.0 servings per day, which is below national averages and recommendations.

智 藤田, Satoshi FUJITA · Institutional Repositories DataBase (IRDB) · Japan

At Keisen Women's College farm in Japan, the potential of using Low-Input Sustainable Horticulture (LISH) and vegetable gardening as environmental education materials was investigated over 15 years, starting in 1984. The study found that 16 different vegetable varieties could be grown organically, but cucumbers, other fruit/vegetables, and Cruciferae were virtually impossible to grow organically. However, damage could be reduced for some varieties through specific cultivation methods, and the vegetable garden was found to maintain beauty even in cold seasons and provide a suitable hands-on learning experience for environment and food.

This paper examines the "myth of the urban peasant" in Russia, which suggests urban households survive economic collapse through subsistence agriculture. Based on official and survey data analysis, it shows that while many urban households grow food, those with low incomes are least likely to do so, and subsistence production complements rather than replaces paid employment. Furthermore, those who grow their own food work long hours for little return, spending no less on purchased food than those who grow nothing.

A study in Southern Flevoland, Netherlands, from 1994 to 1996, assessed inoculum sources of potato late blight. It found that 74% of early disease foci in commercial potato fields were linked to nearby infested refuse piles. Infected seed tubers, volunteer plants, and infested allotment gardens appeared to be of minor importance for late blight development in potato fields. However, in August 1994, infested organic potato fields became major mid-season infection sources, spreading the disease to adjacent conventional fields.

Dick Foeken, A. Mboganie-Mwangi · Leiden Repository (Leiden University) · Africa

Using survey data collected in 1994 in Korogocho, one of Nairobi's slum areas in Kenya, this study examined whether access to farmland influences a household's food situation. Access to land had a positive impact on urban households' overall welfare, but not necessarily on their food situation. Households with access to a rural plot appeared better off in terms of self-reported food situation than households without any land access, and access to rural land appeared more favorable for food situation than access to urban land alone. Among the very poor households in Korogocho who claimed access to rural land, half did not actually use that land themselves.

A. Mboganie-Mwangi, Dick Foeken · Leiden Repository (Leiden University) · Kenya (Nairobi)

A 1996 study in Nairobi, Kenya, compared the food security and nutritional status of low-income households engaged in urban agriculture with those not farming. It found that urban farmers primarily produced for home consumption and faced theft as a major problem. While the Undugu Society Urban Agriculture Project (USUAP) group showed better food situations and higher energy and protein intakes than other groups, all three groups had inadequate energy intake on average. The long-term beneficial effect of urban agriculture on nutritional status was negligible.
