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.

2018Marit Rosol · · Global
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 the phytotoxicity of copper oxide nanoparticles (CuO-NPs) in lettuce and cabbage, exposing them via leaves for up to 15 days to various CuO-NP concentrations. High foliar Cu uptake occurred, leading to decreased plant weight, net photosynthesis, water content, and necrotic Cu-rich areas. The findings highlighted a potential health risk associated with consuming vegetables contaminated with CuO-NPs.
Contamination & food safetyHealthContested urban green spaces in the compact city: The (re-)negotiation of urban gardening in Swiss cities
2017Simone Tappert, Tanja Klöti, Matthias Drilling · Landscape and Urban Planning · Switzerland
A qualitative study conducted in the Swiss cities of Basle, Berne, Geneva, and Zurich analyzed the political negotiation processes of urban gardening within the compact city framework. Findings demonstrated that urban growth strategies, aiming for efficient and resource-saving reorganization of urban space, are discursively rationalizing current transformation processes. This has led to traditional forms of urban gardening being closed down, displaced to less significant locations for urban development plans, or spatially and functionally transformed, while new forms of urban gardening are emerging in inner-city areas.

2017Andrew Butt, Elizabeth Taylor · Geographical Research · Australia (Victoria)
This paper analyzes planning appeals and media from 2011–2016 in Victoria, Australia, regarding intensive poultry developments, revealing tensions between planning processes and local politics. Planning for intensive farming assumes stability and agricultural primacy, but concerns about agricultural industrialization are live local issues in dynamic peri-urban areas. Code-based planning's certainty does not negate the ongoing, inconvenient politics of intensive peri-urban agriculture.

2017Virginia Webb · New Zealand sociology · New Zealand (Palmerston North)
This research in a Palmerston North, New Zealand community garden examined the struggle over norms and power relations, specifically regarding tobacco cultivation. It found that the garden hierarchy's reluctance to accommodate alternative perspectives on tobacco cultivation revealed a troubling politics of race and class. This reluctance meant the garden's potential to disrupt social hierarchies was unrealized, highlighting how health notions can become a basis for social control.
