This study investigated levels of Cu, Pb, Cd, and Zn in soils and vegetables from 17 urban agriculture farms around the "Calle 100" landfill in Havana, Cuba, during 2006-2007. Findings showed that 35% of soils exceeded typical Cuban agricultural ranges for Zn, and 52% for Pb. Critically, 23% of soils surpassed phytotoxic and international limit levels for Pb, and 12.5% of vegetable samples exceeded Cuban maximum permissible limits for Pb in food for human consumption. The results indicate a need for strict monitoring of horticultural crops in the area due to contamination.

This study screened soil samples from peri-urban agricultural areas to investigate heavy metal contamination and identify heavy metal-tolerant fungi. Results showed that the majority of isolated fungi were resistant to lead (Pb) and chromium (Cr). Among the strains, Aspergillus niger was the most tolerant to Pb with an MIC of 600 mg/l, and Aspergillus flavus was the most tolerant to Cr with an MIC of 400 mg/l.

Miguel Lorente · Dialnet (Universidad de la Rioja) · Global

This paper describes the recent social movement promoting urban gardens as sources of leisure, social interaction, and healthy self-consumption food. Factors such as environmental awareness, increased unemployment, physical exercise for retirees, the pleasure of producing one's own food, and trends are contributing to the creation of small vegetable gardens in and around cities. This small-scale activity allows urban populations to discover and understand the role of agriculture.

Heather McIlvaine-Newsad, Rob Porter · Journal of Ecological Anthropology · Global

This conceptual paper focused on the benefits of community gardens, informed by participant observation and literature from the environmental justice movement. Community gardens are stated to be models for improving health through growing and eating local produce, and instruments for generating social awareness and community change.

This study is based on a University Extension Program titled "The Urban Orchard: A Tool for Inclusion of Children and Adolescents," conducted under the UBANEX Programme 2012/2013 by the University of Buenos Aires. The program aimed to develop children's and adolescents' ability to generate and produce a self-managed urban garden. Program implementation showed that the urban orchard produced positive effects at both inter- and intra-subjective levels, fostering curiosity, creativity, responsibility, self-confidence, self-esteem, self-criticism, teamwork, and the quality of links between subjects.

Kibassa, Kimaro, Shemdoe · Scientific Research and Essays · Tanzania (Dar es Salaam)

A study assessing heavy metal concentrations in soils from selected urban agriculture areas in Dar es Salaam, Tanzania, found that zinc, chromium, cadmium, lead, and copper levels in all six investigated sites were within the Tanzania Bureau of Standards permissible limits. The highest values for copper, zinc, and lead were observed in Tazara Mchichani, potentially indicating pollution from surrounding manufacturing industries. Flooding did not appear to influence the distribution of these heavy metals.

Kelly Donati, Christopher Taylor, Craig J. Pearson · · Australia (Melbourne)

Australian policy initiatives address threats to food production from climate change and petrochemical dependency, as well as socio-economic disadvantage. In Victoria, natural disasters like droughts, bushfires, and floods have increased food costs for low-income households. This case study explores farmers markets and community gardens in Melbourne as potential localized food systems, collecting data between 2009 and 2010 using GIS-based land use descriptions and interviews with local producers.

Fernando Richter · Dialnet (Universidad de la Rioja) · Global

This article examines the current boom in urban agriculture, noting a shift from its historical function of food production to a focus on recreational and leisure activities. It suggests that symbolic dynamics associated with new-ruralism, consumption, and a nostalgic search for authenticity converge in this phenomenon. The study proposes that Leisure Studies offer a valuable perspective for understanding the complexity of urban agriculture as a leisure experience.

Jorge Cotter, Maria J. Cotter, Pedro Oliveira, Pedro Cunha, Jorge Polónia · Journal of Hypertension · Portugal

A 6-month study in northern Portugal evaluated the impact of three interventions on salt intake and blood pressure in 155 children aged 10-12. Interventions included a control, theoretical lessons on high salt intake, and theoretical lessons combined with practical school garden activities (planting, collecting herbs for salt substitution). Only the practical group showed a significant reduction in salt intake (1.1 g/day), with 50.9% of children reducing intake by at least 1g/day, suggesting that combined theoretical and practical education is more effective.

This is a systematic review protocol — not a completed review — that sets out methods for identifying, appraising and synthesizing evidence on how urban agriculture programs affect food security and nutrition in low- and middle-income countries. It notes urban agriculture is widely promoted as providing the urban poor with food and income while improving the urban environment, but also carries potential disadvantages: use of wastewater can contaminate produce, intensive irrigation can spread malaria and water-borne disease and strain limited water supplies, and soil erosion and intensive fertilizer/pesticide use can pose health risks and environmental damage. Despite the current policy drive to promote urban agriculture, the paper states that the evidence base for its benefits and harms is not well understood. As a protocol, it reports planned search, screening, bias-appraisal and synthesis methods rather than results.
