Influence of Social Inequality on Urban Agriculture
2018Kwaku Obosu-Mensah · · Ghana (Accra)
This study examines the influence of social inequality on urban agriculture in Accra, Ghana, focusing on land ownership and cultivation practices. It found that urban residents born or raised in other regions of Ghana are more likely to be middle/upper class, own urban land, and engage in enclosed cultivation. A disadvantage of enclosed cultivation is associated with water supply.

2018Jenny Smart, David Tschirley, Francis Smart, Smart, Jenny Cairns, Tschirley, David, Smart, Francis · AgEcon Search (University of Minnesota, USA) · Mozambique
Food system transformation and changes in diet quality were assessed in Mozambique amidst rapid urbanization and income growth. Rising incomes and processed food consumption were found to be associated with a worsening of negative dietary factors. Furthermore, urbanization, controlling for income, was more strongly associated with a worsening of negative factors than an improvement in positive dietary factors. However, owning one's own farm had a positive and significant effect on nutrition for urban households, primarily driven by reduced purchases of unhealthy foods.

2018Timo Falkenberg, Deepak Saxena, Thomas Kistemann · The Science of The Total Environment · India (Ahmedabad)
A cohort study investigated the contribution of wastewater irrigation to in-household water contamination among urban farming households in Ahmedabad, India, within the context of WASH (Water, Sanitation, Hygiene). Drinking water samples from 204 households were collected four times over 12 months, and E. coli was quantified. Significant positive differences in water quality between point-of-source and point-of-use samples were identified in 78% of households. During the monsoon, the peak of contamination, only 6% of households had access to safe drinking water at the point-of-use. Wastewater irrigation showed an adverse effect on in-household water contamination, with an effect size larger than the mitigation effect of access to sanitation or personal hygiene.
Contamination & food safetyHealthTemporal Dynamics and Motivations for Urban Community Food Gardens in Medium-Sized Towns of the Eastern Cape, South Africa
2018Sky Roberts, Charlie M. Shackleton · Land · South Africa
This study investigated urban community food gardens in four towns in South Africa, using surveys and GIS analysis over three decades. It found that common motivations included cash poverty (37%) and the need to grow food (34%), with reported benefits such as a healthy lifestyle (58%) and food consumption (54%). A significant challenge was theft of garden infrastructure or produce, and there were declines in the number and area of urban community gardens, with only 16% of gardens from the 1980s still operating in the 2000s.

2018John Misenheimer, Clay Nelson, Evelyn Huertas, Myriam Medina-Vera, Alex Prevatte, Karen D. Bradham · Geosciences · Puerto Rico
Total and bioaccessible arsenic (As) and lead (Pb) levels, and their uptake by 10 commonly grown garden plants, were examined in three urban community gardens in Puerto Rico. Total As ranged from 2 to 55 mg/kg and Pb from 19 to 172 mg/kg in soils. Leaves accumulated higher concentrations of As and Pb than edible flesh, with culantro leaves showing the highest concentrations (3.2 mg/kg dw As, 8.9 mg/kg dw Pb).
Contamination & food safetyCommunityHealthOrganic cycleSession J: Debating the inclusion of animals in the Urban Farming Movement in Detroit
2018Michelle Marie Proctor · · United States (Detroit)
Urban agriculture programs in Detroit have seen many urban farms begin to include animals, sparking policy and ethical debates. Supporters claim animals accelerate land remediation, fertilize and aerate soil, and improve petroleum-polluted soils. However, opponents point to problems such as botched slaughters and lack of animal welfare oversight, arguing that backyard animal husbandry should be regulated in the best interests of the community and animal welfare.

2018Sugandhi del Canto, Rachel Engler‐Stringer · Policy Press eBooks · Global
Restrictive covenants, a corporate real estate practice, are identified as a significant barrier to establishing new food stores in older neighborhoods globally. These covenants place conditions on land use, such as prohibiting food sales or grocery store development, making it harder to address existing nutrition deserts. Government support is needed to limit these covenants and develop alternative food channels, including urban agriculture.

2018D.V. Belobrova, Д. А. Шаповалов · Dokuchaev Soil Bulletin · Russia
This study conducted large-scale (1:5000) soil mapping of garden non-commercial partnerships in the Meshchera lowland of Noginsk district, Moscow region. Investigations revealed that initial soils underwent significant transformation since their creation, with soddy podzolic and boggy soils changing into agro-soddy podzolic soils and agrozems due to intensive development and fertilizer use. While these changes reflect increased productivity and quality of allotment soils, the transformed soils are characterized by neutral pH and high/medium mobile phosphorus content, but are poor in exchangeable potassium compared to natural soil profiles.

2018Chhaya Kolavalli · UKnowledge (University of Kentucky) · United States (Kansas City)
This dissertation, based on 26 months of ethnographic fieldwork in Kansas City, examines green urban development and urban agriculture projects from the perspective of residents in an African American majority neighborhood. It argues that dominant narratives of urban sustainability and agriculture, shaped by upper-middle-class white voices, support green development projects that marginalize and displace people of color and the poor. The study documents the lived consequences of these narratives and highlights resistance efforts by minority-led agricultural projects and neighborhood councils.

2018Muhammad Shahid, Camille Dumat, Nabeel Khan Niazi, Sana Khalid, Natasha Natasha · VertigO · Global
Arsenic concentrations exceeding the World Health Organization's recommended limit (10 μg/L) have been frequently found in groundwater in several countries globally, exposing millions to arsenic. This study synthesizes recent interdisciplinary knowledge on arsenic, particularly for urban gardeners and farmers who may face contamination in well water or produced vegetables. Geogenic arsenic poses a major health threat in many countries, especially in Asia, and advice is proposed to avoid and reduce human exposure to arsenic in urban agriculture contexts.
