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.

Chhaya 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.

This paper explores the concept of Urban Agriculture (UA) and discusses its locational and strategic dimensions. Using case examples from cities worldwide, it shows that UA can contribute to the social, environmental, and economic pillars of sustainable city development; however, there are limitations that cities investing in urban agriculture should consider.

Miguel A. Altieri, Clara I. Nicholls · Agro Sur · Global

Although urban agriculture (UA) is estimated to provide 15-20% of global food, its significant contribution to city food self-sufficiency is questionable due to low yields in most existing urban farms. Agroecology can enhance UA's productive potential by offering key principles for designing diversified, productive, and resilient urban farms. This paper describes principles and practices for increasing soil quality and enhancing plant health.

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.

This paper assesses the spatial distribution of heavy metals and potential ingestion risks in Kumasi, Ghana, using geostatistical techniques on topsoil samples. Results from univariate and multivariate semivariogram models showed strong spatial dependence with autocorrelations ranging from 100 to 300 meters. The produced risk maps indicate strong spatial heterogeneity for most soil heavy metals, with extremely high contamination risk found near commercial areas.

Pascale Scheromm, Christophe‐Toussaint Soulard · Geographical Research · France

This paper provides a spatial analysis of agriculture in three mid-sized French cities, focusing on professional farms. It confirms the existence of significant agricultural spaces within cities and the persistence of field-based, market-oriented agriculture. Key determinants in the observed dynamics include the cities' geographies, the impact of land speculation and urbanization on farmers, and the resistance and adaptation processes implemented by some farmers.

This survey evaluated 10,078 hectares of unmanaged land in Lasiana, Kupang city, Indonesia, to assess its capability for urban agriculture. The study found that two land units were classified as Class III land capability due to limiting factors such as soil depth, erosion level, soil fertility, drainage, and stoniness. Recommendations for land management included increasing soil depth and applying urban forest or urban farming development with multifunctional land uses.

This chapter discusses the politics of urban community gardening, positioning it ambiguously between neoliberal/austerity urbanism and progressive urban politics. It argues that urban community gardening can reinforce neoliberal urbanism through land use struggles and gentrification, the role of volunteering in neoliberal urban governance, and governing through community and technologies of the self. The continuous emphasis on self-help in urban green spaces is problematic when civic engagement focuses exclusively on certain groups and values.

This study assessed gardeners' lead exposure in urban agriculture sites (UAS) to improve the derivation of soil assessment criteria. Researchers sampled nearly 280 paired soil and crop samples across 31 UAS gardens in the United Kingdom and measured blood lead levels (BLL) of 43 gardeners and 29 non-gardening neighbors. While 98% of sampled soils had lead concentrations above the current UK UAS soil guideline (80 mg/kg), all participants' BLL were below 0.1 mg/kg despite high soil lead. The study indicated that soil-to-plant concentration factors (SPCFs) used for UAS significantly over-predicted lead uptake.

This review examines the application of food sovereignty principles in urban and peri-urban agriculture in Zimbabwe. It notes that despite urban households integrating these practices into their livelihoods, institutional arrangements governing them remain ambivalent. The review concludes that the failure to involve all stakeholders undermines urban and peri-urban agriculture, leading to increased food insecurity and unsustainable practices.

김정식, 한미영 · · South Korea

This study examined the suitability of urban agriculture expert training programs in South Korea, surveying students in Daejeon in 2018. Over 60% of students viewed experts as knowledge transmitters, with most motivated by qualification acquisition. While major city programs focused on basic cultivation, the study concluded that current curricula are insufficient for future urban agriculture trends. It recommended adding programs on urban community understanding, industrialization, cooperative agriculture, and farm management.

This paper describes urban agriculture as an activity gaining new support but facing difficulties due to inadequate governance. The research identified eight instruments for sustainable urban agriculture, including food security and economic development. It concludes that each city requires specific governance to achieve synergies.

M.K. Saleh, Azher Mustafa · Journal of Agricultural Extension · Nigeria (Kaduna State)

This study investigated food security and productivity among 213 urban farmers in Kaduna State, Nigeria, using interviews and statistical analysis. Results showed that 54.5% of households were food insecure. A regression model predicted that the probability of urban farming households being food secure was 51%, indicating a limited effect on food security despite urban farming efforts.

A postdoctoral project involving collaboratively planting and maintaining a community garden on land that was once part of the East Armidale Aboriginal Reserve in New South Wales, Australia, began in 2014. This research offers a personal narrative of involvement in an anti-colonial multispecies research project within the confines of a neoliberal university, interrogating the potential and limitations of anti-colonial projects undertaken from colonial subject positions predicated on social and environmental privilege.

Marie Gisclard, Richard Raymond · Institut français d’études anatoliennes eBooks · Turkey (Diyarbakır)

This article examines the Hevsel Gardens in Diyarbakır, Turkey, which face sustainability challenges due to the city's growth and an asymmetric relationship where the city dominates the gardens. It highlights the unbalanced relationships between the gardens and the city, stemming from a lack of quality and quantity in water resources. The coexistence and competition of three socio-political projects, including centralized political networks and farmer-specific adaptations, call for a re-examination of this relationship and an alternative to the concentration of powers in the metropolis.
