This study investigated the needs and commercialization challenges of chinampa producers in Xochimilco, Mexico City, to assess the potential of a green label. The analysis, based on a literature review and producers' mental model analysis, found that unresolved issues like commercialization problems, consumers' unwillingness to pay fair prices, soil degradation, and poor irrigation water quality persist. These issues make it difficult for most producers to bear certification costs, indicating that implementing a green label would likely fail to deliver its intended benefits.

This study aimed to identify the impacts of land use change experienced by urban farmers in Kapanewon Kasihan, Indonesia. Using a deductive-qualitative approach, it was analyzed that urban development has both positive and negative impacts on farmers. The most significant negative impacts included pollution, decreased productivity, and the squeezing of urban agricultural land, which could lead to long-term environmental quality degradation and further spread of land use change.

Arnim Wiek, Stefanie Albrecht · Urban Agriculture & Regional Food Systems · United States (Phoenix)

A multiyear transdisciplinary project in Phoenix, United States, analyzed the development of a sustainable urban food forest enterprise. The project built a coalition of supporters, secured a suitable site, codeveloped a vision and action plan, and fundraised a major start-up donation. However, research findings indicate that despite achieving success factors to some extent, an underdeveloped sustainable entrepreneurial ecosystem jeopardizes long-term success and multiplication efforts.

Annie Stéphanie Nana, Timo Falkenberg, Andrea Rechenburg, Annet Adong, Anne Ayo, Pierre Nbendah, Christian Borgemeister · Agriculture · Cameroon

This study investigated factors influencing farming practices and disease prevalence among 130 vegetable producers in the lowlands of Yaoundé, Cameroon, through a cross-sectional survey. Education level and farm size were positively associated with overall fertilizer use, while pesticide usage was positively associated with years cultivated but negatively with land ownership. Waterborne disease prevalence was linked to education level, and malaria prevalence to farmer gender. The location of cultivated areas significantly influenced reporting malaria and headaches, concluding that despite associated health risks, vegetable production is necessary for farmers’ livelihoods.

Kinanti Safitri, Oekan S. Abdoellah, Budhi Gunawan, Parikesit Parikesit, Yusep Suparman, Akhmad Mubarak, Margareth Pardede · The Qualitative Report · Indonesia (Bandung)

This mixed-method study, involving 107 export-scale urban farmers in the Bandung metropolitan area, Indonesia, investigated their adaptation during the COVID-19 pandemic. Farmers prioritized commercial agriculture and adapted through market access, agricultural management, and financial resource strengthening. However, some adaptation methods were not environmentally friendly, as farmers increased reliance on synthetic inputs and used cold storage on open land, leading to intensive, non-environmentally friendly agricultural practices.

André Torre, Brenno Fonseca · Sociologia Ruralis · Brazil (São Paulo)

A study on the development of peri-urban agriculture in the São Paulo Metropolitan Region, Brazil, was conducted based on expert interviews, analysis of the regional daily press, and local information sites and blogs. It was found that territorial opposition between different land uses is one of the main factors preventing food production in urban and peri-urban areas. The study investigated local conflicts, their location, their link to agriculture, the consumption of agricultural soils, and the typology of opponents and supporters of this activity.

Bikram Pratim Bhuyan, Ravi Tomar, Amar Ramdane-Chérif · Sustainability · Global

An extensive systematic review of knowledge representation techniques used in smart agriculture, specifically in the urban agricultural domain, was conducted. The review found that spatial-temporal characteristics were rarely approached, a generalized representation technique to include all agricultural domains remains an issue, and a proper validation technique was missing in such ontologies.

Raquel Yurie Hioki, Moacir Roberto Darolt · Archives of Veterinary Science · Brazil (Curitiba)

This study, conducted in Curitiba, Brazil, and its metropolitan area, aimed to discuss the risks and benefits of legalizing urban poultry farming. Through interviews with key informants, challenges were identified across sanitary, legislative, and commercial areas, urban chicken breeders, and bird management. The main challenges cited were sanitary and environmental risks, mistreatment, irregular slaughter, and neighborhood disturbances, which could be addressed through activity regulation, registration of farms, technical monitoring, and implementation of pilot projects.

Noëllie W. Kpoda, Hamidatu S. Darimani, Adama Ouéda, Idrissa Ouédraogo, Gustave B. Kabré · Agricultural Sciences · Burkina Faso (Ouagadougou)

This study evaluated the risk of parasitic infection among vegetable producers in Ouagadougou, Burkina Faso, who use polluted water, employing a quantitative microbiological risk assessment method. Protozoa and helminths from 9 species were detected in irrigation water, with Ancylostoma sp. eggs being common and severe across all water types. Contamination risk was higher for groups using raw wastewater than for those using well water, and halved for those using treated wastewater; however, regardless of water type, gardeners had an approximate 9.83 × 10−1 pppy probability of Ancylostoma sp. infection.

April M. Roggio, Jason Evans · Sustainability · Global

Participatory Guarantee Systems (PGS) are locally-rooted agroecological governance mechanisms that have garnered interest globally. However, there is little evidence of their development in the United States, where community supported agriculture (CSA) and farmer's markets grew instead, though many of these mechanisms failed to sustain interest and support. This study explores factors driving PGS creation in other global regions and identifies factors shaping a different trajectory for local agriculture in the United States.

Alesandros Glaros, Geoff Luehr, Zhenzhong Si, Steffanie Scott · Land · China

An exploratory study investigated the manifestation of urban agriculture within the context of Ecological Civilization (EC) in four Chinese cities, through four months of on-site interviews and surveys with urban agriculture practitioners. The study found that capital-intensive and peri-urban approaches to urban agriculture are favored under EC, while small-scale intra-urban initiatives are actively discouraged in policy and risk overlooking grassroots efforts and local residents' needs.

This research in the Arrondissement of Zinvié, Africa, investigated agricultural land governance through surveys of 109 people and field observations. Findings indicate rapid urbanization is causing anarchic land occupation and uncontrolled consumption of agricultural space, with renting being the dominant land access mode (50%). From 2010 to 2020, cultivable land decreased by 517.69 hectares due to urbanization, highlighting significant governance challenges.

Paulo Silvano Magno Fróes-Júnior, Fabrício Khoury Rebello, Marcos Antônio Souza dos Santos, Cyntia Meireles Martins, Maria Lúcia Bahia Lopes, João Paulo Borges de Loureiro · Conjecturas · Brazil (Belém)

This study interviewed 63 urban farmers in Curuçambá, Belém Metropolitan Region, Brazil, analyzing business management and entrepreneurial skills amidst urbanization and crime risks. It found that 98.41% of businesses are family-managed, but 52.38% have little management experience, with 76.19% never keeping financial records and 81.71% never seeking technical assistance. A significant 33.33% of farmers rated criminality as "very high" severity, indicating that a lack of public safety severely limits commercial performance and investment in urban agriculture.

Anithadevi Kenday Sivaram, Logeshwaran Panneerselvan, Aravind Surapaneni, Elliot Lee, Kurunthachalam Kannan, Mallavarapu Megharaj · Environmental Advances · Australia

This study assessed 19 commercially available composts, garden soils, and potting mixes in Australia for 38 per- and polyfluoroalkyl substances (PFAS). Total PFAS concentrations ranged from 1.26 to 11.84 µg kg−1 (dry weight), with total perfluorinated carboxylic acids (ƩPFCAs) being higher than perfluoroalkyl sulfonic acids (PFSAs). The total oxidizable precursor assay (TOPA) showed an increase in short-chain ƩPFCAs (0.48 to 7.63 µg kg−1) in composts and potting mixes, indicating transformation of PFCAs precursors. The measured concentrations of short-chain PFCAs in soil substrates have the potential to contribute to plant uptake and food chain transfer of PFAS to humans.

Organic stores, trendy coffee shops, and food initiatives generally associated with the alternative food movement, such as farmer's markets and community gardens, have become a clear symbol.

Rafael Lima Oliveira, Gabrielly Dos Santos Lima Oliveira, José Raimundo Oliveira Lima · P2P E INOVAÇÃO · Brazil

This study investigated the role of cooperativism as an element for strengthening urban and peri-urban agriculture (AUP) in Brazil. Findings revealed that the absence of public policies and credit availability are limiting factors for AUP. Increased production and product outflow are also difficulties faced by these farmers, which could potentially be resolved through cooperation.

Héritier Mesa · Cahiers d études africaines · Congo (Kinshasa)

This article explores social trajectories and inequality dynamics among informal workers in Kinshasa, focusing on labor relations within the informal economy. Drawing from ethnographic data on street bread, second-hand clothing, and urban agriculture, the study finds that limited access to capital constrains many workers to sell their labor power with weakened bargaining power, revealing unequal social positionalities.
