This study aimed to develop a sustainable social entrepreneurship model for urban farming initiatives in Johannesburg. Through a literature review and qualitative interviews with experts, findings highlighted several important challenges that limited urban smallholder farmers' ability to ensure the financial viability and sustainability of their farming initiatives. These challenges included limited accessibility to farming land, markets, funding, and knowledge regarding setting up and managing small agri-businesses.

This study compiled evidence from over 200 food forests worldwide, with detailed insights from 14 exemplary food forests in Europe, North America, and South America, gained through site visits and interviews. Findings indicate that most food forests perform well on social-cultural and environmental criteria, such as building capacity, providing food, enhancing biodiversity, and regenerating soil. However, for broader impact, food forests need to enhance their economic viability, as they currently show a deficit in this area.

A survey of 40 urban farmers and gardeners in Louisville, Kentucky, assessed their agricultural practices and barriers. Most growers engaged in urban agriculture for non-commercial reasons, with only 11% operating for profit, and smaller farms were less likely to be profitable or certified. Common sustainable practices included composting (60%) and crop rotation (54%), while challenges involved limited space, farm certification access, pests, and lack of record-keeping.

This article analyzes a charity-led community gardening project in a disadvantaged northern English community, which operated for three years with external funding. While it successfully engaged marginalized people, leading to increased skills, confidence, reduced isolation, and improved wellbeing, the project faced significant challenges requiring professional management. Crucially, after the funding ended, the community garden's future was fragile, and the long-term sustainability of outcomes for marginalized participants was vulnerable due to economic viability issues.

Amid a COVID-19 outbreak that caused 15,587 deaths in São Paulo city through December 2020, this study examined effects on urban agriculture from April to August 2020, drawing on two government surveys (2,100 farmers in São Paulo state, 148 in São Paulo city) and two qualitative surveys of volunteers from ten community gardens and seven urban farmers. Fifty percent of farmers reported being affected by the pandemic through drops in sales, particularly those who depended on intermediaries, and 22% said obtaining inputs had become difficult. No municipal support was provided to urban agriculture in São Paulo, and pre-existing problems worsened; activity in community gardens declined, though none closed permanently.

This chapter examines the 2000s housing financialization wave in Hungary, analysing financial over-inclusion and exclusion -- alternating dynamics of reaping gains and externalizing costs. It shows that "intermediate" rural-urban transitional zones are prime areas for high-risk mortgage lending while also containing spaces excluded from institutionalized housing finance, using as its case study an allotment garden where households combine formal jobs and mortgage repayment with informal dwelling to reduce housing costs, arguing that such informal reproductive solutions function as a resource for capital accumulation through inclusion and exclusion.

A study on Malaysia's Movement Control Order (MCO) noted the extension may effectively contain the pandemic's spread but is expected to have a devastating impact on food security, and proposed urban farming as a means of generating household income and food security for the low-income B40 group. Econometric modeling of the effect of lockdown measures and COVID-19 on selected vegetable prices found that not all vegetables reacted uniformly to lockdown measures; price increases were associated with reduced household purchases and income, denying people access to food security. While the substitutability of vegetables allowed some switching to cheaper options, the study states that higher food prices themselves deny people access to food security.

In-depth interviews with community supported agriculture (CSA) farmers in the Pioneer Valley of Massachusetts, United States, examined their livelihoods. CSA farmers earned more farm income than other US farms and other farms in the region, but their earnings remained far below the median national household income. Despite this income shortfall, CSA farming provided non-market social, ecological and economic benefits tied to feeding the community rather than producing for mass markets, which farmers described as a significant source of well-being.

Valéria Borges Yonegura, Henrique Manoel da Silva · Confins · Brazil

A study of the Tatuquara neighbourhood and surrounding areas of Curitiba, Brazil, combining bibliographic review, historical-geographic analysis, and interviews with community gardeners (horteiros) conducted over 2017-2018, found that urban gardens improved local life, landscape and community safety and fostered topophilia and place attachment. Despite being used in city marketing, the practice's continuity is threatened by the possible end of a partnership with the electric utility and by pressure from the real-estate market.

A comparative study of Community Supported Agriculture (CSA) models in Canada and China was conducted based on interviews and survey results. The study developed a framework to compare CSAs based on initiators’ motivations, economic characteristics, ecological practices, shareholder relations, and community building. It was found that CSAs in both Canada and China are struggling to maintain the movement’s original values and economic viability, moving away from the traditional ‘risk sharing’ approach to more flexible payment mechanisms. However, other original tenets of the CSA model, such as member engagement, are strengthening.

Tezcan Mert-Cakal, Mara Miele · Agriculture and Human Values · United Kingdom (Wales)

This article examines Community Supported Agriculture (CSA) projects in Wales as social innovation, exploring their emergence, innovative role, and transformative potential. Based on qualitative data from four different CSA case studies in Wales, the research showed that Welsh CSA cases play distinctive roles in the social economy, satisfying needs for ecologically sound and ethically produced food and empowering individuals at a micro level. However, the paper argues that for CSA initiatives to become 'workable utopias', they need to overcome barriers preventing replication, participation in macro-level policies, and scaling up, particularly concerning economic sustainability and resilience on a small scale.

A random sampling survey in Dhulikhel, Kavrepalanchok district, Nepal, found that while all respondents perceived rooftop farming as beneficial, many could not practice it due to constraints like fear of roof damage. Practicing farmers also faced difficulties managing rooftop gardens due to a lack of proper knowledge and reliance on non-recyclable planting materials.

Non-market sales, barter, trade, donations, and other creative transactions have been integral to Community Supported Agriculture (CSA) since its inception, promoting creativity and new economic thinking due to its advance payment system for unknown harvests. Based on qualitative field research, primarily in the Northeastern United States, this chapter examines the innovative transactions that have enabled CSA and other Community Supported Enterprises (CSEs) to grow. While acknowledging that the 'Community Supported' model has not solved the challenge of providing adequate incomes for producers or attracting diverse participants, the chapter presents evidence of CSA as a vibrant system connecting producers and consumers through creative transactions.

This review discusses vegetable production in South Africa, focusing on the impacts of root-knot nematodes (Meloidogyne species) on small-scale farming communities. The review highlights that these nematodes are a primary pest, causing delayed crop maturity, reduced yields, poor quality produce, and escalating production costs. This leads to substantial income losses for farmers and the abandonment of community gardens, intensifying challenges for vegetable production and food security.

This descriptive study, using purposively sampled primary data from 30 farmers in Danurejan sub-district and 25 farmers in Jetis sub-district, Yogyakarta City, Indonesia, examines the contribution of urban farming income to household income through farm income analysis, a one-sample t-test, household income analysis, and multiple linear regression. Urban farming produced a positive annual income (Rp 112,883/year), but its contribution to total household income (Rp 46,579,988/year) was only 0.24%. This low share was attributed to the very small quantity of crops cultivated per household — for example, 4 polybags/year of bird's-eye chili, 10 polybags/year of large chili, and 11 polybags/year of mustard greens. Farmer age, education level, quantity of crops grown, and seedling price were the factors significantly affecting urban farming income.

This research inspected existing practices and obstacles in rooftop farming in Nagdhungha and Birauta, Nepal. Two practitioners were interviewed and 60 non-practitioners were surveyed. Results show that rooftop farming can benefit the environment by reducing atmospheric carbon and assist urban areas by reducing stormwater management costs, with a high willingness to practice rooftop farming among urban dwellers.

This paper discusses different types of urban agriculture (UA) to assess its potential for future food production. Conventional open-air farming is found to be rarely commercially viable for meaningful food production, though it offers community, educational, psychological, and environmental benefits. High-yielding Controlled Environment Farming (CEF), while potentially contributing substantially to food output, is highly capital and knowledge-intensive and likely to develop at city fringes due to economic considerations.

A focus group interview with young urban farmers in Daegu, South Korea, explored job creation through urban farming. Participants perceived farming as physically demanding and unrewarding, despite seeing urban farming as a promising industry for job creation. They also noted a lack of national support policies and difficulties in participation. A contradiction was identified between the young farmers' desire to adopt labor-saving new technologies and the goal of creating jobs through traditional farming.

This study analyzed technical-productive and socioeconomic limitations to urban agriculture adoption within the Urban and Periurban Agriculture Network (RAUP) in Xalapa, Veracruz, Mexico. Based on 25 questionnaires from active members and 10 from sporadic participants, both groups agreed that the main constraints are socioeconomic, such as lack of space and limited free time, which are linked to urban lifestyles. Technical-productive limitations were not considered relevant.

This study analyzed technical-productive and socioeconomic limitations to urban agriculture adoption among members of the Network of Urban and Periurban Agriculture (RAUP) in Xalapa, Veracruz, Mexico. Researchers applied 25 questionnaires to active members and 10 to non-practicing participants. Both groups of RAUP participants identified socioeconomic factors, such as lack of space and limited free time due to urban lifestyles, as the main constraints, while technical-productive limitations were not considered relevant.

This research explored the potential of urban agriculture in Cape Town, South Africa, and Maputo, Mozambique, through two baseline surveys among urban farmers and home gardeners, as well as qualitative in-depth interviews. Findings indicated that urban farmers and home gardeners add nutrients and diversity to their diets and can partly contribute to their income. However, in Cape Town, main challenges included access to local and external markets, fair pricing, and sovereignty in production.

This paper explores market-oriented urban agriculture along the Yamuna River in Delhi, India, from the farmers' perspective. Using a multi-method Rapid Assessment Process, the study investigates how urban agriculture is practiced and what factors influence farmers' livelihood decisions. The research argues against assuming the sustainability of urban agriculture, emphasizing the need to understand city-level conditions and their impact on farmers' economic viability.

Catherine Dobbins · Journal of the Arkansas Academy of Science · United States (Arkansas)

This mixed-method needs assessment in Arkansas investigated urban agriculture, using interviews with 16 urban farmers and a quantitative survey of County Extension Agents (CEAs) with a 57% response rate. Farmers expressed varied needs, and while they viewed the Cooperative Extension Service (CES) positively, CES lacked specific resources for small-scale sustainable farming. The survey revealed that 70.2% of CEAs reported low or nonexistent concentrations of urban farming in their counties, indicating potential barriers for agents to work with urban farmers.

Lemi Gonfa · · Africa

This paper reviewed the role of urban agriculture in socio-economic and environmental sustainability in Africa, drawing on theoretical and empirical literature. While urban agriculture is recognized for job creation, improved diet, and environmental benefits like urban greenery and biodiversity, challenges such as difficult land access, lack of experience, financial support, training, and credit facilities, as well as low land productivity, animal grazing, and theft, were identified. These factors present potential negative externalities and hinder the development of urban agriculture.

Interviews with school food environment staff across Canada examined how provincial nutrition regulation changes affected food procurement. While the regulations opened opportunities to improve nutrient content and involve local producers or school gardens, some schools struggled to procure nutritionally compliant food because of higher costs of transporting produce to rural, remote or northern communities and logistical problems such as spoilage. Regulations improved food environments in some schools, but others still require more support.
