2021ELISABETH MEYER-RENSCHHAUSEN · Materia Arquitectura · Germany (Berlin)
This paper discusses the historical presence of gardens and urban agriculture in cities, from ancient civilizations to modern times. It notes that after disappearing in the late 19th century, family gardens were replaced by garden city movements, and after WWII, land was offered for cultivation. The paper suggests that the growing demand for garden plots in the 20th and 21st centuries and the global community gardening movement represent a new type of urban agriculture.

2021T. G. McCarthy · Michigan Historical Review · United States
Joseph Stanhope Cialdella's book, "Motor City Green," describes how Detroit residents maintained various relationships with nature, including growing plants and food in their backyards and vacant lots, throughout the city's 130-year history. The book presents a series of episodes, from 1890s vacant lot programs to the Detroit Urban League's 1920s efforts to encourage gardening among African American residents and 1930s summer camps, which defined ideas about urbanism, nature, and relationships among residents.

2020Manuela Alves da Cunha, Lidice Almeida Arlego Paraguassú, José Geraldo de Aquino Assis, Arthur Benjamin de Paula Carvalho Silva, Ryzia de Cassia Vieira Cardoso · Journal of Ethnobiology and Ethnomedicine · Brazil (Salvador)
A city-wide mapping of active food gardens in Salvador, Bahia, Brazil, followed by site visits and interviews with gardeners. Only 18 active food gardens could be located in the whole municipality; 17 took part (8 communal, 9 private). Gardeners averaged 55.76 years old and were 52.9% male overall, but women made up 87.5% of communal-garden gardeners and had higher education levels. For 52.9% of respondents the garden was their main source of income; 82.4% ate the produce, 70.6% also sold it and 47.1% donated. Fifty-nine neglected and underutilized species (NUS) were recorded, with 76.5% of respondents reporting they eat 19 of them. The gardens supply affordable food and food diversity without government support — but the very small absolute number of active gardens in a city of this size is equally part of the finding.

2020Jeffrey Alan Hoffmann · · United States
Hoffmann examined oral histories and interviews (1995-1996, 2014, 2017) with elders of multiple ethnicities in a working-class urban agricultural neighborhood in the U.S. Southwest. The study found that while ecocultural memory fosters trust in shared water relationships, historical anxieties stemming from urban development violence can impede communities' ability to organize to protect and restore ancestral waterways.

2019Cinthia Asunción Peralta-González, Rodolfo Mondragón-Ríos, Eduardo Bello Baltazar · Estudios Sociales Revista de Alimentación Contemporánea y Desarrollo Regional · Mexico (San Cristóbal de Las Casas)
This qualitative study analyzed sociocultural spaces and communication mechanisms used for collective learning and knowledge appropriation regarding medicinal and gastronomic plant use among residents of San Cristóbal de Las Casas, Chiapas, Mexico. Ethnographic techniques were employed with members of the urban agriculture network Sembrando Jovel, citizens from the Santa Lucía neighborhood, and various city markets. Results identified formal, non-formal, and informal spaces linked by communication mechanisms such as intergenerational coexistence, daily practices, experimentation, knowledge exchange, classes, courses, workshops, diplomas, and mass media. The study was limited to a small number of families (four cases) in the Santa Lucía neighborhood regarding the domestic sphere. As a result of appropriation processes, knowledge about medicinal and gastronomic plant uses has been re-signified, adopting critical stances against food industries and in favor of personal, social, and cultural well-being.

2019In-Kyoung Hong, Young Chae, Sang-Mi Lee, Young-Bin Jung · Journal of people, plants, and environment · South Korea
This study aimed to improve the diversity of urban gardens by identifying suitable crops from "Gwanhyuji," an agricultural book from the Joseon Dynasty. Fifty-three crops were selected based on traditionality, historicity, health functionality, and popularity, and their properties were evenly distributed. The study suggests that applying traditional knowledge to urban agriculture can transform urban gardens into resources offering educational and traditional values, thereby enhancing their diversity and utility.
