Findings indicate that urban farming positively impacts food accessibility, availability, and affordability, while also promoting environmental sustainability and socio-economic inclusion. However, challenges such as limited space, regulatory hurdles, and public awareness gaps hinder its widespread adoption.

Rabia Admin, Malka Shahzadi, Malika Shahzadi, Muhammed Faisal Rasheed · Social Sciences Spectrum · Pakistan

This study examines women's involvement and empowerment in agricultural activities in Lahore Cantonment, Punjab, Pakistan, based on data from 118 women engaged in agriculture, analyzed using mixed methods including descriptive statistics, chi-square tests, correlation, and multiple regression. The results show that while participation rates among women are high, women are not yet empowered, owing to existing socio-cultural and resource-based obstacles. Significant associations were found between land ownership and women's decision-making, between education and participation, and between access to credit and extension services and involvement in agricultural activities; the correlation matrix showed positive relationships among key variables, and regression analysis identified land ownership, education, and access to credit as significant predictors of women's empowerment. The paper states that changes to law, access to resources, and social support are needed to improve women's agency in peri-urban agriculture, and proposes policy measures including land rights reform, targeted educational initiatives, and improved access to resources.

Kanosvamhira T.P., Magidi M. · International Journal of Agricultural Sustainability · 南アフリカ・ケープタウン／ジンバブエ・ノートン

A qualitative case study comparing the motivations, operational dynamics, land access challenges and legislative contexts of urban agriculture in two contrasting cities — Cape Town (South Africa) and Norton (Zimbabwe) — through stakeholder interviews and policy analysis, guided by social capital theory. In Cape Town urban agriculture is semi-institutionalised, backed by governmental and civil society actors and framed within wider food justice and community development agendas, yet practitioners face significant constraints from land access, urban policy fragmentation and competition over space. In Norton it is largely informal, a survivalist response to persistent socio-economic hardship with minimal formal support but relatively flexible regulation, where land-tenure insecurity and the threat of eviction are the pressing concerns. The paper argues that context-specific legislative frameworks, secure land rights and inclusive urban planning are the enabling conditions, situating urban agriculture within debates on land governance and urban informality.

This study explored how state-initiated, unplanned urbanization in Mbarara City, Western Uganda, affects the sustainability of urban farming and urban livelihoods. The research found that rapid, haphazard urban expansion, lacking strategic planning, has led to significant challenges. These include the emergence of slums, illegal land occupations, destruction of wetlands and riverbanks causing water pollution, and inadequate waste management, all negatively impacting public health and urban farming 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.

This global review examines the development of rooftop agro-voltaic systems (RAVs), which integrate photovoltaic panels with rooftop farming. While RAVs offer benefits like energy production, improved agricultural yields, and environmental conservation, challenges such as efficiency trade-offs, financial constraints, and regulatory gaps limit their widespread adoption. Pilot projects in India demonstrate dual benefits, but these limitations hinder broader implementation.

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.

Ioana Florea · Environmental Sociology · Romania

This paper investigated three collective gardening projects in Bucharest that closed between 2019 and 2021, analyzing what remains of their sustainability capacities and commoning efforts after termination. Findings indicate that while essential commoning aspects like collectivity building and autonomy can endure and transfer to other spaces, cross-class aspects fade away with these transpositions. This reveals that what persists from closed gardening projects is strongly tied to structural historical contexts.
