The study revealed that UPA significantly contributes to Bogotá's environmental resilience, particularly in soil conservation and integrated water management. However, while UPA promises food security, its unstructured value chain limits its impact on economic sustainability.

Francisco Tomatis, Ana Marí­a Bonet de Viola, Ulises Reno, Ouiam Fatiha Boukharta, Luis Manuel Navas-Gracia · · Argentina

In Argentina, public policies like the Argentine Plan Against Hunger and the ProHuerta Program have stimulated urban agriculture to address the food emergency crisis in early 2024. Despite urban gardening being recognized as a crisis-addressing strategy, the existence and future forms of public policies supporting urban gardens remain uncertain amid recent national political changes. Several barriers to integration and consolidation of these programs are highlighted.

Meznanat Tame, Kassahun Gashu, Bantayehu Ayalew Workineh · City Territory and Architecture · Ethiopia

In north-west Ethiopia, a study analyzed urban expansion driving factors, compensation, and livelihood coping strategies of displaced farmers surrounding medium-sized towns. Primary data was collected through 350 survey questionnaires, two FGDs, and six key informant interviews. Findings revealed that compensation was mostly cash-based, and social relationships and community values decreased after displacement. The study suggests a need for proper urban land governance with a participatory approach that includes farmers, and for appropriate urban planning and land policy to improve urban land use efficiency.

This study investigated Spanish consumers' perceptions of five lettuce cultivation systems using explicit and implicit methods with 105 participants. Local/small agriculture was most favorably regarded, while urban community gardens were perceived as less safe for lettuce production. High-tech greenhouses were considered safer but less sustainable, and vertical indoor farming elicited a surprise reaction due to low familiarity.

Stefan Galley, Rita Saleh, Patrick Bottazzi · Journal of Rural Studies · Switzerland

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.

This article explores the circularity of organic matter streams in Nkayi, an intermediate city in Congo, through interviews and observations. The qualitative inquiry reveals the coexistence of institutional household waste streams, supported by a development project, and informal organic matter streams, identified through intra- and peri-urban agricultural practices. These streams are subject to various socio-territorial, political, and economic tensions.

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.
