This case study in Brooklyn, New York, used mixed qualitative research methods to investigate the political possibilities of urban agriculture for fostering food justice. Findings indicate that problematic contradictions rooted in the neoliberalization of urban agriculture limit the transformative possibilities of farming the city as currently practiced in Brooklyn. The study suggests that longstanding agrarian questions are informative for critically interrogating urban agriculture as a politicization of food.

A survey of Wisconsin-certified organic vegetable farmers investigated the relationships between farm characteristics, marketing strategies, and farmers' perceptions of profitability and quality of life. The data indicated that farmers selling into farmers' markets and through community-supported agriculture (CSA) were more likely to be dissatisfied with their profitability. Conversely, farmers selling into wholesale markets and restaurants/institutions were significantly more likely to be dissatisfied with their quality of life.

This study in the Middle East and North Africa region investigated the relationship between urban agriculture and food security in two peri-urban locations: Bebnine, Lebanon, and Wadi el Seer, Jordan. High food insecurity was prevalent in both locations, demonstrating that producers were more food insecure than non-producers. Food security was found to be strongly associated with poverty and the number of household members.

This study used multiple land use scenarios to assess different spaces in Montréal, including residential gardens, industrial rooftops, and vacant land, that could be allocated to vegetable production. Results indicated that implementing hydroponics on industrial rooftops could easily satisfy Montréal's vegetable demand, though these operations are generally costly. Utilizing only vacant space also has the potential to meet the city's demand with lower operating costs.

Laura Oliven Silberfarb, Sonja Savre, Gayle Geber · Preventing Chronic Disease · United States (Hennepin County)

Hennepin County assessed the extent to which 41 cities were engaged in making policy, systems, and environmental (PSE) changes to increase residents' access to healthful food. Results revealed that some cities, particularly those with higher resident demand for healthful food, are making nationally recommended PSE changes, such as sponsoring farmers markets. However, cities moved more slowly to make changes in areas with perceived negative cost consequences or lesser public demand, such as parks and recreation vending.

Kizito K. Mwajombe · · Tanzania

This study investigated urban agriculture (UA) produce marketing in three Tanzanian municipalities. Findings showed UA farmers lacked pre-arranged contracts with buyers, limiting their marketing, and faced problems including poor packaging, bylaws, taxes, and difficulty meeting consumer preferences. Farmers also lacked direct links to retail and consumer units like supermarkets.

Using a combination of remote sensing and GIS, this study assessed the rate of agricultural land-use change in the Kaduna metropolis, Nigeria, between 1980 and 2012, classifying and comparing four satellite images (Landsat MSS 1980, Landsat TM 1990, Landsat ETM+ 2005, and Nigeria Sat X 2012). The study found a significant reduction in agricultural land and continued disappearance of farmland over the period, which it links to loss of livelihoods, reduced food supply, and increased poverty. It states that this has raised concerns about the sustainability of urban and peri-urban agriculture (UPA) production in the study area, with small-scale farmers the most affected.

Against the backdrop of demographic projections that global population will reach 9.4 billion within the next 50 years, requiring an additional area of fertile land roughly the size of Brazil that does not exist on the planet, this study evaluated the economic viability of a Canadian vertical farm model as a sustainable urban-rural food production alternative. Using the NCIC method via a participant-observer approach, the study reported the model as economically viable and sustainable, as well as innovative in flattening production chains.

Oliver Moore, Olive McCarthy, Noreen Byrne, Michael Ward · Journal of Agriculture Food Systems and Community Development · Europe

This paper examines one of the earliest and most prominent community supported agriculture (CSA) initiatives in Ireland, focusing on its organizational restructuring under productivity pressure. CSA is built on sharing risk and reward, and some uncertainty is treated as acceptable, but in this case the realized risk of insufficient produce, once pushed to its limits, became in fact unacceptable to members. The process by which this member-owned and member-operated CSA critically self-assessed and restructured after this shortfall is termed "reflexive resilience" — a description of an initiative that had to acknowledge a real produce shortfall and rebuild, not merely one that anticipated shocks in the abstract.

Michela Felicetti · Advanced engineering forum · Italy

A paper examining whether the food hub concept can be applied to the Piana di Sibari area of Calabria, Italy, designated a Quality Agrifood District (DAQ) under regional law. After identifying features of the food hub concept within the area's largest cooperative, the paper argues that this arrangement represents an opportunity for small farmers to access conventional food supply chains from which they would otherwise be excluded. It frames food hubs as a hybrid of alternative and conventional food networks and, notably, as a way to address the economic viability problem faced by local food initiatives such as community-supported agriculture (CSA)—that is, the paper's premise is that CSA-type local food initiatives struggle to be economically viable on their own.

This study examined two tomato production areas in Burkina Faso with potential for counter-seasonal production aimed at Ghanaian urban markets, identifying the main obstacles to developing a horticultural supply chain: the monopsony power of Ghanaian traders and insufficient road quality causing high mechanical-damage losses in transport. Using a spatial-temporal simulation model to assess transport effects on tomato quality, the study found refrigerated transport is not a necessary condition for successful trade, since climate conditions alone do not severely harm quality, and concluded that regional diversification of exports offers Burkina Faso producers the best opportunities for improving their position in the chain, given the persistent trader monopsony and infrastructure constraints.

Ryan E. Galt · Economic Geography · United States (California)

A study of 54 Community-Supported Agriculture (CSA) farms in California's Central Valley used qualitative and quantitative data to explain farmers' earnings. An ordinary least squares regression analysis revealed that farmers' age, number of employees, and CSA type strongly influence earnings. The study found that the moral economy of CSA often results in self-exploitation due to farmers' strong sense of obligation to members, despite allowing for economic rents.

Soraya Pourjavid, Hassan Sadighi, Hossein Shabanali Fami · RePEc: Research Papers in Economics · Iran (Tehran)

This study identified constraints affecting urban agriculture in Tehran, Iran, by surveying 320 city dwellers across 22 municipal districts. The most important constraints identified were "high start-up costs" and "lack of knowledge among managers and authorities." Factor analysis revealed seven factors explaining 67.36% of the variance, including financial-economic and technical aspects.

Wen-jiang Li, Linjun Li, Guoyu Qiu · Journal of Integrative Agriculture · China (Shenzhen)

Water and electricity-use patterns in Shenzhen, South China, were analyzed from 2001 to 2009. Water and electricity use per GDP in agriculture was the highest among sectors, indicating inefficiency. Traditional agriculture in Shenzhen will not be sustainable during urbanization and industrialization, except for high-tech intensive agriculture with low water and energy costs, and has been gradually substituted by industry, construction, residential life, and services.

Phil. Caleb Mireri · African Journal of Agricultural Research · Kenya (Kisumu)

This study surveyed 194 urban farmers in Kisumu municipality, Kenya, to assess urban agriculture's role in income, employment, and food supply. It found that most urban farmers and their employees receive very low income, with a mean monthly income of US$135 (US$0.64 per person per day), which is below the acceptable one dollar a day per person. Urban agriculture primarily supplements food requirements for the urban poor and provides income for a few commercial farmers.

Andrew Butt · Economic Papers A journal of applied economics and policy · Australia

This article reviews changes in farm output and structure in peri-urban regions around Australia's cities. It concludes that farming in these regions is changing differently from other agricultural regions, with productivity centered on a few high-value activities. The majority of peri-urban farming, while potentially providing landscape services, is unable to adjust to changing productivity regimes, creating vulnerabilities for these farming systems.

This paper examines the rise of vertical farms, arguing that they advance the corporate food regime and promote urban elite consumption. It differentiates vertical farms as local food projects that reproduce the capitalist industrial system rather than challenging it, facilitated by devalued built environments and labor surplus in neoliberal cities. The study concludes that these farms reproduce troubling trends in the corporate food regime, signifying capital's ability to standardize food cultivation and incorporate it into factory-like production systems.

Atănăsoaie George Sebastian · Annals - Economy Series · Global

Community Supported Agriculture (CSA) farms are an alternative to conventional agriculture but face numerous policy issues related to product, price, distribution, and promotion. A literature review indicated that farmers need to offer more flexible basket content in terms of quantity and product type, and consumers require information on product preparation and preservation. To offset the negative impact of high prices, measures such as cost reduction, flexible payment rescheduling, and compensation for financial resource deficits are necessary.

WU De-hu · Anhui nongye kexue · China (Zhengzhou)

This study elaborated on the significance of developing characteristic agriculture in China's Central Economic Zone, using Zhengzhou urban agriculture as an example. It identified existing problems in urban agriculture development, including understanding deviation, extensive development, market confusion, short industrial chains, low specialization, and harsh environments. The research proposed countermeasures such as strengthening government macro-control, perfecting compensation mechanisms, and promoting scientific innovation and industrialization.

This study conducted 13 in-depth interviews with farmers to assess their perceptions of Freight Farms, a company growing leafy greens and basil in adapted shipping containers. Most farmers doubted the economic feasibility of Freight Farms, questioned its technologies, and noted the lack of organic certification.

Philani Moyo · Journal of Human Ecology · Zimbabwe

This study qualitatively examined the role and contribution of urban agriculture to household food security, employment creation, and income generation among low-income working-class and urban poor households in Bulawayo townships, Zimbabwe. It was found that urban food production significantly contributes to household food access and security, improving dietary diversity and nutritional intake. However, the potential of urban agriculture is constrained by factors including land tenure insecurity, erratic water access, small plot sizes, inadequate capital for optimizing plot productivity, and ambivalent application of urban land-use laws.

Michael R. Hoadley · Illinois Digital Environment for Access to Learning and Scholarship (University of Illinois at Urbana-Champaign) · Global

A talk by Michael Hoadley, founder of Chicago firm Fewzion, discussed challenges in vertical farming and controlled environment agriculture. The presentation emphasized the importance of framing discussions within the context of economically self-sustainable models, free of dependence on policy subsidy and philanthropy. This highlights concerns about policymakers' over-zealous view of urban agriculture as a panacea for social ills.

This study analyzed the determinants of commercialization among 230 urban vegetable farmers in Oyo and Lagos states, southwest Nigeria, using primary survey data and a Tobit model. It found that farmers' participation in domestic and regional markets remains low due to various constraints, notably poor market access. The average farm size was 0.05ha, and the average market participation index was 0.73. Factors influencing commercialization included age, farm size, association membership, education, distance to market, and input costs. The study concluded that social capital significantly affects market participation, and recommended proactive support from governments and NGOs to facilitate farmer organizations and market linkages.
