Benno Gammerl, Rainer Herrn · sub\urban zeitschrift für kritische stadtforschung · Global

This article outlines the theoretical, empirical, and political potential of the tension between affective disruptions of ordered structures and the emotional processing of power-infused spatial relations. It uses urban gardening practices and gentrification debates as examples to demonstrate how analyzing dynamic interactions between spaces and feelings can foster a critical perspective on urbanity, particularly regarding issues of equity. The study focuses on the ambivalent dynamics and effects of emotional-spatial processes.

Martin Dyer, Richard M. Mills, Beatrice Conradie, Jenifer Piesse · Open University of Cape Town (University of Cape Town) · South Africa (Cape Town)

This paper investigates the efficiency relationships between inputs and outputs of urban micro-farms in two Cape Town townships, Nyanga and Khayelitsha. Data Envelopment Analysis (DEA) applied to 33 producers supplying a social enterprise box scheme revealed an average overall efficiency of 72.4%. Overall efficiency was negatively correlated with land holdings and the use of compost and seedlings, indicating efficiency losses with greater input quantities. Furthermore, it was not shown that mulching or operator experience increases profitability.

Yuki Kato · Journal of Agriculture Food Systems and Community Development · United States (New Orleans)

This case study, based on ethnographic observation and interviews, examined an alternative food market in a New Orleans neighborhood to understand different views of "community." The study identified four distinct groups—community gardeners, locavores, hipsters, and local residents—each with different expectations for the organization. Findings did not demonstrate a unified community emerging around this organization, with no single group staking a claim on it.

Qing Guo · · China (Dalian)

This paper, based on the China urban agriculture development report 2013 and a SWOT analysis, studied the development of urban modern agriculture in Dalian. The study found that the agricultural industrial structure, shopping basket program, agricultural management system, land circulation, and agricultural information technology have restricted the development of Dalian's urban modern agriculture.

Elvis Albert Robe Wandscheer, Rosa Maria Vieria Medeiros · LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas) · Brazil (Porto Alegre)

This study descriptively and qualitatively analyzed the socioeconomic dynamics of urban agriculture in Porto Alegre, Brazil. It highlighted issues in the demarcation of urban and rural spaces, showing that many areas designated as urban possess distinctly rural characteristics. The most significant impacting factors were markets and real estate speculation. The study concluded that while urban agriculture is relevant to the municipality, it faces difficulties arising from competition for space, which can lead to the extinction or displacement of production activities to other areas.

Rosangela Medeiros Hespanhol · Confins · Brazil (Natal)

This study analyzed the trajectory of farmers from AMIGS (Association of Friends and Producers of Vegetables Residents of Sitio Gramoré and Adjacencies), a significant vegetable supplier in Natal, Brazil, who have been transitioning from conventional to organic production since 2012. The organization of farmers through the association and partnerships with companies and institutions were crucial for enabling this change, reducing dependence on intermediaries through direct sales at ecological fairs. However, problems related to the individual acquisition of inputs and conflicts with farmers still using conventional systems were observed.

Abdul‐Halim Abubakari, Laura Atuah, B. Banful, Hypolite Bayor · Journal of Soil Science and Environmental Management · Ghana

A study in Ghana reviewed literature and surveyed farmers on soil amendments for urban horticulture. The review found that research on soil amendments has been limited to land management and nutrient recovery, not addressing quality issues for specific production systems. Farmers adopt varying application rates due to lack of standardization, and barriers include technology for collection, funds for purchase, and labor employment.

Ryan E. Galt, Katharine A. Bradley, Libby Christensen, Julia Van Soelen Kim, Ramiro Lobo · Sociologia Ruralis · United States (California)

A study of 111 CSA farms in California examined the effects of competition within alternative food networks. Analysis showed that perceived competition is negatively correlated with CSA farms' profitability, farmer satisfaction, various indicators of CSA's social embeddedness, and two community food security strategies. Competition was found to undermine some commonly held CSA values, specifically fair farmer compensation and strong member-farmer relationships.

Eric Weaver · Suburban Sustainability · Global

This review details the relationship between key planetary systems and the many adverse impacts of industrial agriculture, drawing from top-tier journals. Research indicates that industrial agriculture is a major force pushing environmental limits, with multinational corporations continuing to influence national environmental regulations. Current literature debates whether political systems can institute sustainable solutions, suggesting that grassroots efforts may be the most viable solution to displace the industrial agriculture model.

Kin Wing Chan · Open Research Exeter (University of Exeter) · Hong Kong

This study examines the politics of meat production in Hong Kong's 2006-2007 License-Buy-Back Scheme (LBBS), focusing on pig farming. It investigates how the LBBS served as a tactic to reduce and control the pig farming industry, contrasting it with urban vegetable farming which holds a more positive aesthetic image. The research highlights a scarcity of studies on why certain forms of urban agriculture are valued more than others.

West Africa, Olufunke Cofie · · West Africa

An examination of urban agriculture (UA) development in West Africa reveals that despite its known benefits for food supply and livelihoods, UA is not fully recognized as an important component of urban development. This is due to high land demand from other sectors and perceived health risks by authorities. Policy makers need to address issues to institutionalize UA and integrate it into urban development plans.

Claire L. McCarty, Pamela Dixon · Journal of case studies · Global

A case study on the West Central Food Hub Producers' Co-op reveals that the group decided not to proceed with starting the Food Hub Co-op. The decision was made because the costs for management, infrastructure, and delivery would far outweigh the co-op's profitability, leading to its discontinuation.

Sarah James · Area · Australia (Sydney)

This paper argues that small-scale family farmers on Sydney's urban fringe are directly connected to and reliant on the mainstream food system for their economic viability. It highlights that a localized focus on threats and solutions risks neglecting the impact of supermarket power and consumer choice on these producers. The study emphasizes the need to examine the continuing connection between the mainstream system and 'local', small-scale producers to achieve food system change.

David Mkwambisi, Andrew J. Dougill, Philip Antwi‐Agyei, C. P. Chabvuta · CABI eBooks · Malawi

Research in Lilongwe and Blantyre, Malawi, assessed urban agriculture's potential to improve soil quality, crop yields, and livelihoods. Preliminary evidence showed urban waste could address food insecurity and soil nutrient benefits, but several constraints in waste management were identified. City authorities are not proactively utilizing organic municipal waste for soil quality and agricultural production benefits.

Kristina Satterlee · Digital Commons @ Connecticut College (Connecticut College) · India (Mumbai); United States (New York City)

This comparative study of urban agriculture in Mumbai, India, and New York City, USA, utilized in-depth interviews with urban farmers and secondary research. The research revealed that farms and gardens in lower-income areas in both cities had access to significantly fewer resources than their counterparts in wealthier areas. Additionally, both movements struggled to form networks across socioeconomic divides.

Pei Xin Koh · DR-NTU (Nanyang Technological University) · Singapore

This study aimed to verify the viability of vertical farming systems with LED supplementary light compared to conventional hydroponic farming systems, focusing on energy consumption, cost, plant growth quality, and yield. Experiments with Butterhead lettuce showed that LED lights contributed 90.12% of the total energy consumption in the vertical farming setup. The commercial viability and realistic cost levels of vertical farming have not been established, and a detailed cost-benefit and energy-benefit analysis is yet to be made.

Georgeanne M. Artz, Linda Naeve, Artz, Georgeanne M., Naeve, Linda · AgEcon Search (University of Minnesota, USA) · United States (Iowa)

A study in Iowa indicated that small-scale farmers considering scaling up production face challenges balancing increased labor costs with the need for specialized machinery. The study collaborated with five groups of farmers who shared different pieces of machinery, developing sharing agreements. While the article provides an overview of the benefits and challenges of machinery sharing, the abstract does not state specific findings that machinery sharing resolved economic viability issues.

Alan Hallsworth, Alfred Wong · International journal on food system dynamics · United Kingdom (Portsmouth)

This empirical case study examined the potential for urban gardening to contribute to individual food security. Focusing on Portsmouth, England, the study found that prevailing economic and social structures hamper the likelihood that urban gardening can offer much greater food security. Realistically, contemporary urban gardening most closely resembles a middle-class pursuit for personal enjoyment, rather than a significant contributor to food security.

Stephen R. Miller · · United States (Newark, New Jersey)

This article proposes a new approach to financing local food, viewing it as a finance problem similar to urban manufacturing, to scale up local food production. It explores the necessity of large-scale urban agriculture, focusing on vertical farms, and examines creative financing examples like AeroFarms in Newark, New Jersey. The paper suggests deploying existing and potential financing types, modeled on economic development agreements, to advance local food initiatives.

Sara Parme · Educational Media Reviews Online · Global

The documentary film "Plant This Movie" (2014, 83 min) explores our relationship with food and the wasted space and resource of the 21st-century lawn. This film, one of many similar documentaries on urban farming, proposes learning from and improving upon past mistakes of the Green Movement. It notes that many agricultural nonprofits, including one highlighted, fail due to lack of funding, and while it suggests sustainability efforts should be run like a business, only a fraction of the film is dedicated to this aspect.

Silene Maciel dos Santos, Samuel Ferreira da Fonseca, Luiz Andrei Gonçalves Pereira · Dialnet (Universidad de la Rioja) · Brazil (Pirapora-MG)

This study analyzed the spatial distribution of urban agricultural activities in the Sagrada Família neighborhood, Pirapora-MG, Brazil, through a literature review. It examined urban agriculture practices, their socio-economic role, and the problems and challenges faced by urban agriculture actors in the neighborhood. The study concluded that the identified issues suggest urban agriculture as an emancipatory process.

Gabriel R. Valle · Aztlán A Journal of Chicano Studies · United States

This essay explores the self-valorization of work in community gardens to advance a grounded theory of time and value, which has been lacking in Chicana/o studies. Urban community gardens are pivotal to the environmental justice movement, with Chicana/os playing a central role. The essay proposes a revolutionary logic of labor through reframing time and value, aiming to reconnect community gardeners to the means of their own production and reproduction. By creating "gardens of sabotage," communities challenge capitalism by reclaiming the value of work and confronting orthodox notions of economy, work, citizenship, community, and time.

徐晶, 吴聪 · 中国土地 · China (Wuhan)

This paper analyzes the practice and problems of "multi-plan integration" in Wuhu Street, Huangpi District, Wuhan City, a rapidly urbanizing area dominated by modern urban agriculture. Wuhu Street faces issues such as the disorderly sprawl of construction land and low land use efficiency. The study proposes targeted policy recommendations based on these findings.

Sabine Lefkowitz · · United States (Portland)

This thesis examined the relationship between socioeconomic status (SES) and outdoor time in Portland, Oregon public elementary schools. The study found that higher SES elementary schools spend more time outdoors than low SES schools. This disparity amplifies existing disadvantages for children in high-poverty schools, suggesting an inequity in outdoor time provision.

Geneviève S. Metson, Elena M. Bennett · PLoS ONE · Canada (Montreal)

This study quantified the role of urban agriculture (UA) in phosphorus (P) cycling in Montreal, Canada, using existing data and surveys of local UA practitioners. In 2012, Montreal imported 3.5 Gg of P in food, with 2.63 Gg accumulating in landfills, 0.36 Gg discharged to local waters, and only 0.09 Gg recycled through composting. UA was found to be only a small sub-system in the city's overall P cycle, contributing just 0.44% of the P consumed as food. Although recycling rates within the UA system are high, the land area dedicated to UA is too small to accommodate all P waste produced on the island.
