2020Herman Parfait Awono-Ambene, Laurelle Djieukap Njieyap, Patrick Akono Ntonga, Josiane Etang, Christophe Antonio‐Nkondjio, Cyrille Ndo, Jacques Étamé, Flobert Njiokou, Serge Hubert Zébazé Togouet · Journal of Environmental Science and Public Health · Cameroon (Yaounde)
This study analyzed water and soil samples from three market garden sites in Yaounde, Cameroon, from October to December 2016, for physicochemical characteristics and parasite identification. The analysis of 82 samples revealed the presence of 3 protozoans (Entamoeba histolytica, Sarcocystis sp., and Giardia intestinalis) and 11 helminths in the soil. The presence of viable helminths suggests that harmful soil pathogens such as protozoans and helminths can spread through market gardening.

2020Debra J. Davidson · International Journal of Sociology of Agriculture and Food · Global
This study assessed the multiple emergent effects of urban agriculture activities through an extensive, interdisciplinary literature review to discuss its disruptive potential. It suggests that producing food in cities is not inherently transformative in itself, but the potential and observed new forms of social engagement emerging in many contexts can create institutional conditions that may disrupt conventional agri-food systems by building social capital as much as physical capital.

2020Noiry Pérez Pompa, Santa Laura Leyva Rodríguez · Sinergia Académica · Cuba
A diagnosis of farms infested by Dichrostachys cinerea (marabú) in urban and suburban agriculture was conducted at Los Téllez farm in Becerra, Las Tunas municipality, Cuba. Soil quality indicators for reddish-brown Fersialitic soils over granitoids were evaluated across four land-use systems: two infested by D. cinerea and two agricultural systems cultivated for 10 years after marabú deforestation. Results showed that D. cinerea systems exhibited the highest soil quality index, based on organic matter, bulk density, and earthworm biomass. Conversely, cultivated systems achieved the lowest accumulation of organic carbon, oligochaete density and biomass, and total porosity.

This article considered the potential risks of contamination in urban agricultural products. Urban agriculture, particularly in large cities, areas with heavy traffic, or near industrial zones, can lead to the accumulation of heavy metals in vegetable crops due to air pollution, traffic pollution, and other sources. Consuming these contaminated fresh vegetables is noted to potentially deteriorate human health.
Contamination & food safetyHealthUrban–rural linkageA systematic, mixed studies review of the outcomes of community garden participation related to food justice
2020Kate Gardner Burt, Gail Mayer, Rachel Paul · Local Environment · Global
A systematic review analyzed 277 community gardening articles to assess outcomes of community garden participation related to food justice, synthesizing 31 studies. Many positive impacts were indicated across seven social and dietary outcomes. Community garden participation was positively correlated with community connectedness, but evidence demonstrating diet improvement was neutral. Methodological rigor in study design and lack of participant racial/ethnic and socioeconomic diversity were common issues, leaving the effectiveness of community gardening as a strategy for a more equitable food system unclear.

2020Martí Rufí-Salís, Felipe Parada, Verónica Arcas‐Pilz, Anna Petit‐Boix, Gara Villalba, Xavier Gabarrell · Frontiers in Plant Science · Spain (Barcelona)
This study investigated a closed-loop crop cascade system in a Barcelona rooftop greenhouse, using tomato leachates to irrigate five successive lettuce cycles. The results showed that low yields (below 130 g per lettuce plant) were obtained when the cascade system was used during the early stage of the donor crop, as the nutrient amount, especially nitrogen, was insufficient for the receiving lettuce crop. Additionally, electrical conductivity values became too high (near 3 dS/m) at the end of the donor crop cycle, indicating limitations in maintaining optimal conditions throughout.

2020Alison Hope Alkon, Yahya Josh Cadji, Frances C. Moore · New York University Press eBooks · United States (California)
In North Oakland, California, USA, collaborations between food justice organizations and residents, spurred by gentrification, were explored. The partnership and merger of Phat Beets Produce and the Self-Help Hunger Program were analyzed, initiated after a community garden was used in a gentrification advertisement in 2014. While this collaboration created a strong alliance, it was found to be insufficient to resist the structural forces driving gentrification.

2020Razzaq Ahmed, Shaukat Khan, Khalida Mahmood, Ahsanullah · Irrigation and Drainage · Pakistan (Karachi)
Agricultural activities in the Gadap Basin, Karachi, Pakistan, showed a declining trend over two decades from 1997 to 2016. Analysis of 13 irrigation water samples revealed that water quality had severely degraded, with sodium concentration substantially increasing, especially near sand and gravel excavation sites. While 100% of samples were suitable for irrigation in 1997, this dropped to almost 50% by 2016, and SAR also decreased, indicating irrigation water quality degradation. Satellite imagery further showed a 60% decline and degradation of agricultural land in the basin during the same period.

2020Stefan Staehle · sub\urban zeitschrift für kritische stadtforschung · Global
This study offers an alternative perspective on the critical practice of urban gardening, highlighting the ambivalence of the phenomenon. Specifically, the decoupling of social and artistic critique is shown to lead to a programmatic weakening of initiatives and their co-optation by neoliberal urban policies. This can reverse the critical practice of spatial appropriation into its opposite.

2020Luca Sára Bródy, Mandy de Wilde · Local Environment · Netherlands (Amsterdam)
Based on a qualitative study of 19 community gardening projects in Amsterdam, this research argues that community gardens function as “controlled space.” Various institutional governance actors, including local government, welfare organizations, green NGOs, and housing associations, exert varied levels of influence and control over the gardens. These relations both impair and enable the civic participation of gardeners, the inclusive potential of gardens, and an alternative, local food provision and distribution.

2020Adrián H. Hearn, Thaís Mauad, Chris Williams, Luís Fernando Amato‐Lourenço, Guilherme Reis Ranieri · Journal of Urbanism International Research on Placemaking and Urban Sustainability · Australia (Melbourne)
This article analyzed the phenomenon of urban agriculture promotion by real estate developers and community associations in Melbourne and São Paulo. Developers of upmarket condominiums advertise urban agriculture as a purchasable commodity, but the gentrifying effects of these developments deepen rather than alleviate social and environmental ills. In contrast, community projects in four case studies emphasized urban agriculture's ability to confront the long-term neglect of land, employment, and environment.
