This qualitative study compares three Swiss communal agricultural prosumption (CAP) types: allotment gardens (AGs), community gardens (CGs), and community supported agriculture (CSA), using Grounded Theory. It found that community-centred CAPs (CSAs, CGs) generate political agency but face financial barriers limiting participation. Individual-centred CAPs (AGs) offer autonomy but have high knowledge requirements and lack political leverage, posing crucial challenges for long-term viability. The study concludes that targeted policy and institutional strategies are needed to ensure the continuity of all CAP types.

Ylva Wallinder, Maria Langa · Environmental Sociology · Sweden

A study investigated the consequences of institutional policy change on urban gardening practices in Swedish municipalities over the last decade. Local sustainability policies have led to an increasingly business-centered model, which clashes even with entrepreneurial gardens. This shift caused associational gardening to give way to an extended focus on entrepreneurship and food production, representing a "green rationalization" of gardening practices in urban sustainability policies that hinders their sustainability potential.

Joshua Zeunert, Scott Hawken, Josh Gowers · Land · Australia (Sydney)

A critical GIS analysis was conducted for Sydney and neighboring regions in NSW, Australia, to understand and advocate for Sydney's food production capacity. The study challenged the notion that Sydney's metropolitan landscape has low inherent biophysical quality for agriculture. Despite current metropolitan planning policy that marginalizes agricultural productivity, datasets revealed western Sydney is biophysically well suited for agriculture. Sydney's overall agricultural capacity was found to be comparable to five of six other coastal regions of NSW and superior to at least two, challenging current planning orthodoxy and policy.

Yanxin Liu, Victoria Chanse, Fabricio Chicca · Land · New Zealand (Wellington)

This study evaluated the role of urban agriculture (UA) in enhancing post-disaster food security in Wellington, New Zealand, a region highly prone to earthquakes. It calculated vegetable self-sufficiency by mapping potential productive land, estimating vegetable yields, and assessing post-disaster food demands across multiple scenarios. Potential productive land accounted for 0.3% to 1.5% of the total area, primarily distributed in the eastern part of the city. Results indicate that Wellington's vegetable self-sufficient rates through UA range from 3% to 75%, with higher rates for displaced and vulnerable populations. Realizing this potential will require stronger policy support and integration with urban planning and disaster preparedness.

Rapidly growing urbanization presents complex socio-economic and environmental challenges, necessitating a sustainability approach that encompasses social well-being (the brown agenda) and ecological protection.

Claudia Rochael Oliveira · Terra Livre · Global

This article argues that while vertical farms (VFs) are often presented as indispensable for sustainable cities, their purported sustainability is difficult to achieve without structural changes to reduce social inequalities. Critiques of urban agriculture, including VFs, point to their contribution to gentrification, racialization of space, and vulnerability to real estate capital, indicating a critical finding regarding equity. The article advocates for VFs to be appropriated by social movements to foster critical stances against conventional agriculture and catalyze urban utopias.
