A paper on rapid urbanization and rising urban poverty shifting the historical locus of food insecurity from rural areas to the cities of Africa uses baseline survey data from the African Food Security Urban Network (AFSUN), carried out in 11 cities in 9 southern African countries in 2008-2009, to demonstrate extremely high levels of urban food insecurity. It finds that lack of access to food results primarily from household poverty, high unemployment, and limited income-generating opportunities rather than any absolute food shortages. The paper also shows the growing importance of supermarkets, and finds that urban agriculture plays a relatively insignificant role in the food sourcing strategies of the urban poor.

Les Levidow, Katerina Psarikidou · · United Kingdom

In Manchester, England, environmental and health issues have been folded into a wider agro-food strategy aimed at making the city "more sustainable." With support from state bodies and charities, several initiatives have expanded access to fresh, healthy food, particularly in "food deserts," mobilizing resources, skills, and voluntary labor through "community engagement" to create "community spaces" for social inclusion. Manchester's agro-food networks shorten supply chains by linking peri-urban agriculture more directly with urban consumers and by promoting urban agriculture grounded in local resource mobilization and personal trust, offering an alternative to conventional agro-food chains; food relocalisation is described as helping overcome socio-economic inequalities and health problems, with Manchester initiatives cooperating to build environmentally sustainable, socially just, healthy communities and reconstructing local identities and social commitments, within a national policy context that advocates food relocalisation but provides little actual support. Despite that activity, the larger food system in Manchester remains dominated by conventional agro-food chains, and community food initiatives play only a marginal role, leading practitioners to discuss how to overcome these limitations; from 2010 onward, the UK government's austerity regime is described as undermining state support further, making community engagement even more important for mobilizing resources.

A study in a peri-urban agricultural community in Ghana explored attitudes towards sanitized human excreta as fertilizer, collecting data from 154 households. It found a general negative attitude towards fresh excreta and its handling. While residents accepted excreta could be used as fertilizer, they were unwilling to use it on their own crops or consume such fertilized crops.

A study surveyed 700 randomly selected households across Kano (Nigeria), Bobo Dioulasso (Burkina Faso), and Sikasso (Mali) to explore the relationship between household socioeconomic status (SES) and participation in urban and peri-urban agriculture (UPA). The results showed no significant differences in UPA participation rates across socioeconomic groups. Instead, UPA participation was significantly and positively related to household size.

This study evaluated the contribution of community gardens to alleviating food insecurity for 53 community gardeners in Maphephetheni, KwaZulu-Natal, South Africa. Using the Household Food Insecurity Access Scale, it was found that 89% of these households were anxious about food supplies, consumed insufficient food, and were severely food insecure. Additionally, 72% consumed poor quality food. Community gardens were unable to solve the problem of food insecurity, but their contribution to consumption cannot be entirely ignored.

M. Tshitangoni, A. Okorie, Joseph Francis · Scientific Research and Essays · South Africa

In Vhembe District, Limpopo Province, South Africa, the performance of 30 poverty alleviation projects (12 community gardens, 8 poultry, 2 piggery, 2 bakery, 6 other) was reviewed. Based on structured questionnaires with 108 respondents, project performance differed by type. All bakery projects were successful, poultry projects achieved 62% success, and community garden and other projects each achieved 33% success. In contrast, all piggery projects performed poorly.

John James Okiror, Biryabaho Matsiko, Joseph Oonyu · Journal of Agricultural Education · Uganda

This study, conducted in eight primary schools in Uganda, compared the learning achievement of pupils taught using supervised home gardens and those taught using school gardens. Data were collected over four school terms using questionnaires, focus group discussions, interviews, observations, and a posttest examination, and analyzed with a t-test. Findings showed no significant difference in knowledge achievement between the two groups of pupils.

This article examines the contemporary importance of household food production in poor urban communities across 11 Southern African Development Community (SADC) cities. It finds that urban food production is not particularly significant in most communities, with many more households relying on supermarkets and the informal sector for food access. Furthermore, few households derive income from selling produce, though the situation varies considerably by city.

Jonathan Crush, Bruce Frayne · Journal of Southern African Studies · Southern Africa

This article reviews urban food sources in Southern African cities, focusing on supermarket expansion, its impact on informal food suppliers, and the relative insignificance of urban agriculture for poor urban households. Findings from an eleven-city survey by AFSUN are presented, highlighting that urban agriculture has limited significance in addressing urban food insecurity in the region.

Shinichi TAHARA, Sayaka SHIOYAMA, Hideharu KURITA, Toru Terada · Journal of The Japanese Institute of Landscape Architecture · Japan

This study in Japan aimed to identify the actual amount of agricultural production by measuring harvested products from two urban agricultural gardens. It found that production from an 'experience farm' was sufficient for annual household consumption, while allotment gardens could not reach these amounts. At the district scale (500m radius) in this study, urban agricultural gardens could cover more than 10% of all vegetable consumption by urban residents.

A mid-term evaluation was conducted on 3103 California public schools (80.6% of applicants) to assess the effectiveness of the California Instructional School Garden Program (CISGP). Many schools reported not achieving their predicted goals related to the CISGP grant, with only 39.4% of schools accomplishing all their garden-related goals. Additionally, 37.8% of schools reported that their school gardens were negatively affected by the California budget deficit, suggesting that the discrepancy between predicted and actual grant utilization may be due to a combination of budget shortfall and insufficient grant award amounts.

An assessment of Cuban urban agriculture's production and distribution outcomes finds that the most successful subprogram is fresh vegetable production, which has grown rapidly island-wide, while other subprograms remain active but less developed. Distribution occurs through thousands of points-of-sale, MALs, self-provisioning, and MAEs, with social consumption at workplaces, hospitals, and schools. Urban agriculture plays a significant role in improving Cuban diets but has not led to food sovereignty; other outcomes cited include employment generation, environmental benefits, and community building.

This paper evaluates the sustainability of the Market Basket (MB), a modified Community Supported Agriculture program run by Post Oil Solutions in Brattleboro, Vermont, USA, that provided local, fresh vegetables to low-income consumers at wholesale prices across two locations over two years, drawing on the author's experience as market coordinator, focus groups, interviews, and secondary data. Over 60 people participated in the MB during that period, and the paper argues the MB was an effective approach for increasing produce consumption, but issues affecting its sustainability remained unresolved — most notably funding to support a coordinator and increasing participation among generationally low-income consumers — with steps to address both currently underway.

Morongoa Rosina Pako · · South Africa

This qualitative study assesses the Mogabane Community Garden Project in South Africa to determine why it did not reach its objective of poverty reduction in the community. It situates the project against South Africa's poverty lines — roughly 33% of the population living on less than R271/month, 50% on less than R422/month, and 79.1% on less than R1,230/month, with the highest poverty rates in the Eastern Cape (68.3%) and Limpopo (60.7%) provinces and the lowest in the Western Cape (20%) and Gauteng (28.8%) — and the government's post-1994 anti-poverty programs spanning social assistance, employment generation, enterprise development, basic household security, social services, disaster relief, and employment-related social insurance. Against this backdrop, the study assessed the Mogabane project and confirmed that it failed to achieve its poverty-reduction objective.

Senthot Sudirman, Irham Irham, Slamet Hartono, Azwar Maas · · Indonesia (Yogyakarta)

This study analyzed agricultural land use changes in peri-urban Yogyakarta from 1996-2007, covering 922.17 ha in Sleman, 1,888.60 ha in Bantul, and 1,082.79 ha across 47 villages. Factors like agricultural production exchange value, irrigated land, built area percentage, population density, education, and land price significantly influenced land change rates, which negatively correlated with distance from the city. However, agricultural land percentage to village area, land tax, and dummy variables for Bantul and Kulon Progo did not significantly influence these rates, and the changes negatively impacted regional food loss, availability, and farming sustainability prospects.

Kevin C. Matteson, Gail Langellotto · Insect Conservation and Diversity · United States (New York City)

The ability of adding 70 plants of seven native wildflower species over two years to augment beneficial insect richness, including bees, butterflies, and predatory wasps, was assessed in New York City community gardens. Bayesian analyses failed to find a strong influence of the native plant additions on beneficial insect richness, even after correcting for prior floral abundance. Butterflies and megachilid bees were found to heavily utilize introduced ornamental and crop flowers in these gardens, even when native flowers were present.

Dick Foeken, Samuel Owuor, Alice Mwangi · Children Youth and Environments · Kenya

A survey was conducted in almost all primary and secondary schools in Nakuru Town, Kenya, to examine the extent to which school farming contributes to school feeding programs. The survey found that while school farming and feeding programs are common practice, school farming substantially contributes to school feeding programs in relatively few cases.

Eric L. Hazzard, Elizabeth Moreno, Deborah Lane Beall, Sheri Zidenberg‐Cherr · The FASEB Journal · United States (California)

This study evaluated the effectiveness of the California Instructional School Garden Program (CISGP) grants by surveying 749 grantee schools. It found that the development, sustained use, or expansion of gardens was less than expected (p=.01), and fewer schools than expected reported using gardens for instruction (p<.001) or to teach academic subjects (p<.003). Less than 40% of schools reported accomplishing all their garden goals with the funds.

A. C. Egun · Journal of Agricultural Sciences · Global

This paper examined the competencies needed by Agricultural Science teachers in urban areas for effective institutional preparation. Teachers identified 24 competencies for urban agriculture teaching but expressed deficiency in 19 competencies (79.17%). The curricular implication is to include basic Humanities subjects like Geography, Economics, and Commerce in Agricultural Science teacher programs and to effectively implement field trips to strengthen the relationship between theory and practice.

Eva Collins, Kate Kearins · Academy of Management Learning and Education · New Zealand (Auckland)

A sustainability instructor took a graduate class to an eco-village near Auckland, New Zealand, where students observed off-grid homes and community gardens. While New Zealand students were inspired by the alternative lifestyle, two international students from China and Tajikistan expressed that this lifestyle was how they lived at home and they did not wish to live that way, preferring the New Zealand lifestyle. This indicates a limited appeal of the eco-village model to some international students.

A pilot study in Houston, Texas, investigated the impact of 11 established community gardens on property crime numbers using 2005 crime data. Statistical comparisons between community garden areas and randomly selected city areas showed no statistically significant differences in the mean number of crime occurrences. The presence of a community garden was not found to be a predictor of a lower crime rate for a neighborhood.

W. Van Averbeke · Water SA · South Africa (Pretoria)

This study in five informal settlements of Atteridgeville, Pretoria, South Africa, used a pilot study, household survey, and multiple case studies to assess urban farming's contribution to food security and household income. While over half of households participated in urban farming, its contribution to total household income and food security was generally modest. Main constraints included lack of space and limited access to irrigation water.

Kwesi Acheampong, Amoako Mensah, Boatemaa Boateng · Zenodo (CERN European Organization for Nuclear Research) · Ghana

A survey conducted from January to March across five favelas in Accra, Ghana, investigated the impact of community gardening workshops on food security. While participants gained knowledge on sustainable gardening techniques, 45% of respondents still lacked access to necessary resources like seeds and tools. The study concluded that workshops improved awareness but further support is needed to address practical implementation barriers.

Nigel L. Webb, Harrison Kasumba · Africanus Journal of Development Studies · South Africa

In Ezibeleni near Queenstown, Eastern Cape, South Africa, a sustainable-development framework was used to gather empirical findings on vegetable crop cultivation, covering duration of crop consumption, the value of produce to households, environmental benefits, and social/psychological benefits. Both the scale of cultivation and the benefits obtained were found to be modest, reinforcing prior studies that focused on the actual practice of urban agriculture rather than its hypothetical potential.

Chris Hillbruner, Rebecca Egan · Food and Nutrition Bulletin · Bangladesh (Dinajpur)

A study in Dinajpur, Bangladesh, from 2002 to 2003, investigated the impact of seasonality on food security and nutritional status in approximately 600 low-income urban households. Data collected through surveys and child measurements revealed significantly higher rates of food insecurity, wasting, and inadequate growth during the monsoon season compared to the dry season. While dietary diversity and lost work due to weather were identified as pathways affecting food security, child illness was not found to be a significant mechanism contributing to seasonal nutritional declines.
