This chapter argues that rapid urbanization and global capitalism are destroying established livelihoods faster than creating new ones, leading to a growing surplus population. Dispossessed rural classes are reproducing themselves in urban spaces and converging with wage laborers to create agricultural livelihoods in cities of both the global South and North. This makes urban agriculture an important arena for land struggles and a livelihood option, shaping urbanization and socioecological relations.

This study evaluated the quality of irrigation water in urban gardens in Valdivia, Chile, against Chilean standards NCh 1333 and NCh 409. Measured parameters included pH, electrical conductivity, total dissolved solids, and iron concentration. All urban gardens met the established standards, with the exception of the Collico garden, which showed an elevated iron concentration.

Ronald O. Muchelo, Thomas F. A. Bishop, Sabastine U. Ugbaje, Stephen Akpa · Land · Uganda (Kampala)

This study examined urban growth and agricultural land loss in Kampala (1989-2015) and Mbarara (2002-2016), Uganda, using multi-temporal Landsat imagery. Kampala's urban area surged from 7.14% to 55.10%, and Mbarara's from 6.37% to 30.95%, while agricultural land decreased significantly in both cities. A substantial portion of urban growth encroached upon agricultural land (66.7% in Kampala, 57.8% in Mbarara), and unsustainable practices also converted wetlands and forests to agricultural land.

This qualitative study analyzed urban farming business innovation in Surabaya, Indonesia, using the Business Model Canvas (BMC) model across five Women Farming Groups (KWT) and Farmer Groups (Poktan). Findings showed that KWT Guyub Rukun had the lowest revenue, while Poktan Serpis had the highest. The study concluded that low revenue was due to income solely from crop sales and having only one main partner, indicating a limitation in revenue streams for some groups.

Sonia Gatchair · · Jamaica (Kingston)

In Kingston, Jamaica's largest urban space, systematic efforts to stimulate the adoption of commercially viable urban agriculture have lagged. This study examines the facilitators and impediments to commercially viable urban agriculture, arguing that knowledge transfer and the adoption of innovative, technology-driven approaches to farming, financing, and marketing are needed for success.

Hayato IIDA, Yasushi Kyutoku, Wakana KUDO, Yoshiki HARADA · Transactions of Japan Society of Kansei Engineering · Japan (Tokyo)

This study investigated whether the UGS (Urban Green Space Scale), an impression evaluation scale for Tokyo's urban green spaces, could assess impressions of two urban rooftop gardens with flat versus stepped spatial configurations. Based on an online questionnaire (N=670), confirmatory factor analyses indicated a poor or unacceptable fit of urban rooftop gardens to the UGS. Exploratory factor analyses yielded different factor structures, suggesting that new scales are required for evaluating impressions of urban rooftop gardens.

Ophélie Véron · Antipode · Germany (Berlin)

This paper, based on activist ethnography in Berlin's community gardens, people's kitchens, and co-operative projects, explores how community food spaces reproduce, exacerbate, or dismantle power relations and socio-environmental injustices. It systematically examines exclusion and inclusion dynamics, arguing that diversity alone is not a sufficient indicator of social equity and can overshadow forms of injustice. The study exposes the complex, dual nature of Berlin's food activist landscape, where privilege and power contribute to social inequities.

Arcadius Martinien Agassin Ahogle, Sammy Letema · Water International · Kenya (Nairobi)

This article examines the dynamics of irrigated urban agriculture (IUA) and its socio-technical arrangements in the Nairobi catchment, Kenya. The research identified five principal forms of IUA, differentiated by land size, water sources, technicality, actors, and market orientation. A critical finding is that city services do not provide hydraulic infrastructure or agricultural extension for IUA, and state agencies do not account for IUA practices, indicating a lack of governance support.

Adi Nugraha, Raphaël Paut, Ari Ganjar Herdiansah, Susanti Withaningsih, Parikesit Parikesit, Oekan S. Abdoellah · Cogent Food & Agriculture · Indonesia (Bandung)

This study examined the social and economic feasibility of urban farming in Bandung, Indonesia, from the viewpoint of actors, using observations, semi-structured, and in-depth interviews with key informants including urban farmers, community leaders, traders, and government representatives. The findings indicated that urban farming in Bandung is not economically motivated because the practices are not economically profitable for the actors. Instead, social factors such as social collectivity and personal aspirations were found to have propelled the continuity of the urban farming movement.

Anna Rosman, Joseph MacPherson, Marie Arndt, Katharina Helming · Agricultural Systems · Germany

This study investigated the impact of Community Supported Agriculture (CSA) structures on farm resilience among CSA farmers in Germany. A mixed methodology was applied, combining a case study with one CSA farmer and a survey of CSA farmers across Germany. The findings indicated that CSA provides mechanisms for improving farm resilience through increased income security, risk protection, market independence, and satisfaction. CSA farmers demonstrated a high level of perceived resilience compared to non-CSA farmers.

This qualitative case study in East Jakarta, Indonesia, investigated urban farming as a means to balance urban life. Field observations, interviews, and documentation identified several obstacles: a lack of community awareness, limited facilities, and challenges from extreme weather. Proposed solutions include community empowerment, improved facilities, and better climate control and supply chain systems.

Ji-Won Choe, Choong-Hyeon Oh · 환경정책 · South Korea

This study collected and analyzed 223 local government ordinances supporting urban agriculture in South Korea to identify its characteristics and propose institutional improvements. The analysis revealed regional imbalances in institutional support for urban agriculture, indicating a need to expand and revise direct support ordinances. Many direct support ordinances lacked explicit provisions regarding administration, expenses, technology, education, equipment, and locations, requiring amendment. It was also noted that the definition of urban agriculture tended to be narrower than in the "Act on the Promotion and Support of Urban Agriculture," and inconsistencies existed between the titles, purposes, and definitions of related ordinances.

It compares the decrease in agricultural land with the increase in built-up areas. The study highlights that agricultural land conversion negatively impacts food security and proposes a nature-based solution to achieve urban food self-sufficiency.

Chiara Tornaghi · ˜The œGeojournal library · Global

This chapter, based on 15 years of research, discusses key issues hindering urban agriculture from reaching its full potential for human and non-human health. It highlights shortcomings in urban planning policy, specifically the failure to recognize urban agriculture as food production, the invisibility of soil and lack of understanding of living soils, and the disregard for the advisory role of soil care and food production specialists in public land design and soil management. The chapter suggests that agroecological considerations can deepen urban agriculture's ambition in public spaces.

A qualitative survey analyzing the July 2023 Delhi flood and its impact on women revealed that changing climatic patterns over the last 20 years pose survival threats to the most vulnerable group, women and cattle, in urban agricultural societies. The study also indicated that various infrastructure projects have altered the terrain in the Yamuna River floodplains, leading to changes in the river's course and annual floods.

Margaretha Häggström, Mårten Häggström · The Trumpeter · Sweden

This four-year exploratory study in a clearcut in western Sweden investigated the feasibility of cultivating crops in a nutrient-poor, shadowless environment to support biodiversity. The study found that while it was possible to grow potatoes, peas, and some summer flowers without special efforts, it was difficult to grow other vegetables and root vegetables. The project suggests that planting activities in clearcuts may impact people's sense of human-nature identity and respect for the natural environment.
