2019Julian Cribb · Cambridge University Press eBooks · Global
This paper points out that none of the world's megacities can feed themselves, and food chain risks pose an imminent threat of starvation. It presents concepts such as climate-proof food supplies, novel urban food production systems, the importance of urban permaculture, rewilding, and developing wise consumers as solutions to urban food risk. However, it does not explicitly state that these solutions fully resolve the issue of urban food self-sufficiency.

2019Neal Chalofsky · Advances in Developing Human Resources · Global
This paper reflects on the 35-year growth experience of the TPSS Food Cooperative, examining challenges faced by social entrepreneurship. It notes that individuals with vision often lack social movement learning (SML) and human resource development/organization development (HRD/OD) skills to grow and direct organizations, leading to their demise or a shift towards business over social aspects. The paper argues that lessons from the 1970s food cooperative movement can benefit contemporary social entrepreneurships.

2018S. Alan Walters, Karen Stoelzle Midden · Agriculture · Global
Vegetable production on green roofs faces multiple challenges, resulting in minimal current activity despite its potential for urban agricultural sustainability. While intensive green roof systems are considered suitable for vegetable production, extensive systems with shallow-rooted crops like lettuce, kale, and radish show the greatest potential for sustained productivity due to building weight restrictions. Deeper-root crops like tomatoes require constant monitoring of fertility and moisture. Green roofs are not presented as a total solution for urban food provision.

2018Michelle Tendai. Chihambakwe, Paramu Mafongoya, Obert Jiri · Challenges · Zimbabwe
This review maps the use of food sovereignty principles in urban and peri-urban agriculture (UPA) in Zimbabwe, addressing its potential for food security. Despite UPA being ingrained in urban households' livelihoods, institutional arrangements governing the practice remain ambivalent. The review underscores that the failure to involve all stakeholders undermines UPA, leading to heightened food insecurity and unsustainable practices.

2018Robert McDougall, Paul Kristiansen, Romina Rader · Proceedings of the National Academy of Sciences · Australia
This study evaluated small-scale urban agriculture systems in Australia using economic and emergy (embodied energy) analyses. While these systems used land efficiently, they were relatively inefficient in their use of material and labor resources. Benefit-to-cost ratios demonstrated that, on average, the gardens ran at a financial loss, and emergy transformity was one to three orders of magnitude greater than many conventional rural farms. Only 14.66% of all inputs were considered "renewable," resulting in a moderate mean environmental loading ratio (ELR) of 5.82.

2018Suranga Wadduwage · Journal of Land Use Science · Australia (Adelaide)
A multi-criteria spatially-explicit study in the Adelaide metropolitan area, Australia, investigated agricultural land vulnerability to urban sprawl under opposing policy directions. The study showed higher agricultural land vulnerabilities in “Business-As-Usual” and “Accelerated Economic Development” scenarios, extending into rural areas with a leap-frog effect. This confirms the need to sacrifice farmland uses to maintain land supply for urban development under these conditions.

2018Khadija Benis, Rukaia Gashgari, Adnan Alsaati, Christoph Reinhart · DSpace@MIT (Massachusetts Institute of Technology) · Saudi Arabia (Riyadh)
The Urban Foodprints (UF) methodology was applied to assess the environmental sustainability of high-yield urban agriculture in Riyadh, Saudi Arabia, focusing on tomatoes. While urban production in high-yield greenhouses could reduce Global Warming Potential by 9% and water savings were significant, the energy needs of these greenhouses were considerably higher than the baseline. This indicates a trade-off where environmental benefits are partially offset by increased energy consumption.

2018Dona Pickard · International Journal of Sociology of Agriculture and Food · Bulgaria (Plovdiv)
This paper analyzes an urban agriculture case in Plovdiv, Bulgaria, where the municipality cleared over 2 hectares of long-tolerated allotments without involving users, despite NGOs promoting urban agriculture as a social innovation. The case exemplifies barriers hindering social innovation, particularly regarding governance, as the eviction occurred without discussion about the future of urban agriculture. This suggests a lack of civic participation and access to resources for deprived groups.

2018Percy Toriro · · Zimbabwe (Harare)
This chapter explores the governance of urban food production in Harare, Zimbabwe, from 1890 to the present. Evidence indicates that while the practice has gained general acceptance through shifting positions over the years, the status of producers remains uncertain. This uncertainty stems from the lack of full incorporation of urban food production into city plans by planning officials, whose values are out of sync with Harare's lived reality.

2018Joseph Chabi, Miracle C. Eziefule, Rebecca Pwalia, Joannitta Joannides, Dorothy Obuobi, Godwin Amlalo, Charlotte Addae, Alidu Iddrisu, Dominic Acquah-Baidoo, Samuel Akporh, Sampson Gbagba, Kwadwo K. Frempong, Melinda P. Hadi, Helen Pates Jamet, Samuel Dadzie · Advances in Entomology · Ghana
This study in Accra Metropolis, Ghana, compared Anopheles gambiae s.l. species composition and insecticide resistance between two vegetable-growing and two non-vegetable growing areas. All A. gambiae s.l. populations tested were resistant to five insecticides, with lower mortalities observed in vegetable-growing areas (e.g., 2.6% and 12.5% for deltamethrin) compared to non-vegetable areas (36.2% and 38.9%). Anopheles gambiae s.s. and Anopheles coluzzii were dominant in vegetable-growing areas. The findings indicate that urban agriculture contributes to the development of insecticide resistance, which needs consideration in vector control strategies.
Environmental trade-offsHealthBiodiversityUrban–rural linkageThe fate of compost-derived phosphorus in urban gardens
2018Gaston E. Small, Paliza Shrestha, Adam D. Kay · International Journal of Design & Nature and Ecodynamics · Global
Dissolved phosphorus (PO4 3-) and nitrogen (NO3- & NH4+) losses in leachate from experimental raised-bed garden plots were measured. Plots receiving cow manure compost showed high PO4 3- concentrations (5-11 mg/L), while municipal organics compost plots had concentrations an order of magnitude lower (0.5-1.2 mg/L), and no-compost plots had 0.3 mg/L. Phosphorus lost through leachate and harvest accounted for only 1-10% of total applied phosphorus, indicating soil build-up was the dominant fate. This study illustrates a potential trade-off in urban agriculture between crop production and efficient phosphorus recycling from urban food waste.

2018Mohamad Assad, Michel Chalot, Fabienne Tatin‐Froux, Valérie Bert, Julien Parelle · Journal of Environmental Quality · Global
This study investigated element transfer in edible crops (cucumber, pepper, cabbage, lettuce) and poplar (Skado cultivar) grown on soils contaminated with sediments dredged from water canals in the 1960s, aiming to develop a biomonitor. The results showed accumulation of cadmium (Cd) and zinc (Zn) in the edible parts of crops, particularly leafy vegetables, indicating that Cd could be ingested in amounts reaching the tolerable daily intake (TDI) in this context. No accumulation of lead (Pb) was detected.

A study in Ouagadougou sub-urban agricultural fields, Burkina Faso, assessed the impact of using untreated Solid Urban Wastes (SUW) as agricultural fertilizers on soil properties and crop production. SUW amendment significantly increased pH, total C, N, P, and available P, and maize height and biomass yield were 124% and 164% higher in amended plots, respectively. However, trace metal elements (Cu, Zn, Pb, Ni, Cr) concentrations were higher in amended fields, indicating that urban waste carries contaminants posing public health risks.

2018Salvatore Engel‐Di Mauro · Gender Place & Culture · Global
This study discusses two concerns regarding urban community gardens' political potential, suggesting caution. It notes that the community in urban community gardens can be reactionary and capitalism-friendly, potentially impeding the collectivization of social reproduction if it remains largely women's work. Additionally, urban gardeners, primarily women, people of color, and the elderly, may face exposure to toxic substances and increased care work needs due to health effects.

2018Paloma Gonzalez de Linares · International Journal of Design & Nature and Ecodynamics · Hungary (Budapest)
This paper aimed to assess factors contributing to more successful integration of urban agriculture in some cities and to introduce agro-ecology practices in public green spaces and community gardens through landscape assessment and map-based comparison. A key problem identified was the lack of motivation among planners to integrate urban agriculture into urban plans, preventing these green structures from becoming part of the city's landscape and dynamics. The sustainability of food systems was concluded to depend on the city's planning strategy and governance policies.
