The study highlights that despite its potential, vertical farming faces challenges regarding economic viability due to high energy consumption.

Arild Eriksen, Deni Ruggeri, Esben Slaatrem Titland · · Norway (Oslo)

This essay examines urban agriculture from the perspective of an architect and urban farmer/beekeeper practicing bottom-up, participatory design in Oslo. Critical dimensions of urban agriculture in public space include private and corporate claims on these landscapes, and its current aesthetics of impermanence are critiqued. The essay questions the notion that the joy and freedom urban agriculture brings to a community should be built upon and enriched by future development and policy.

Much Faisal Syaputra · Jurnal Administrasi dan Kebijakan Publik · Indonesia (Makassar City)

This qualitative case study critically examined the governance structure of Makassar City's Lorong Wisata program, which integrates urban farming for food self-sufficiency. The study found a fragmented governance network dominated by the municipal government's vertical authority, with weak cross-sectoral collaboration, particularly with universities and private actors. Institutional fragility was evident due to the absence of functional task forces, leading to symbolic rather than substantive coordination.

This mixed-methods study in Addis Ababa, Ethiopia, compared 446 households (223 displaced and 223 non-displaced) to investigate the effects of urbanization-induced displacement on economic capital and food security. Evicted households showed a 72.7% lower likelihood of achieving economic capital security and 93.4% reduced odds of maintaining food security compared to non-evicted households, indicating significant negative differences.

Md. Ashikuzzaman, Mohammad Shahidul Hasan Swapan, Atiq Zaman, Yongze Song · Sustainability · Bangladesh (Dhaka)

This study explored the connection between organizational rational choice in urban rooftop farm (URF) policy development and social innovation, using a literature review and a case study of Dhaka, Bangladesh. Despite the rising popularity of URFs in Dhaka, existing policies and strategies were found to lack clarity and governing mechanisms are absent. The findings suggest that a participatory and co-productive approach, involving community members, local governments, and NGOs, is optimal for URF policy formulation and successful governance.

Christina Frendo · Urban Geography · Canada (Montréal)

This study analyzed how urban agriculture contributes to green gentrification in Montréal. Based on interviews with planners, developers, and community actors, and discourse analysis of municipal policy documents, it showed that ecological initiatives are prioritized over housing, and sustainability fixes reconcile progressive rhetoric with growth imperatives, leading to policy trade-offs that undermine housing affordability. These findings reveal how progressive governments reproduce structural injustices through their ecological transition agendas within the context of a housing crisis.

Francis Mwaijande · African Journal of Empirical Research · Tanzania

This study, using a mixed-methods approach with 600 respondents from urban and peri-urban farmers and agri-food supply chain producers in Tanzania, confirmed urban agriculture's contribution to food availability, accessibility, stability, and utilization. However, it found that urban agriculture is not well-integrated into urban food and poverty reduction policies in Tanzania and is practiced without legitimate policy and legal frameworks. This policy gap indicates an inadequate policy enabling environment for urban agriculture to enhance food security.

Zhongxue Zhou, Fangze Zhao, Bingjie Song · Ecological Indicators · China

This study proposed the concept of agricultural comprehensive ecological effects (ACEE), developed an evaluation framework, and applied it to the Xi'an metropolitan zone, China. A key finding was the observed decrease in the comprehensive ecological effects of agriculture when transitioning from grain planting to urban agriculture due to unsuitable agricultural practices in urbanizing areas. This decline occurs because modern agricultural practices in urbanizing areas are ecologically detrimental compared with natural ecosystems.

Biochar is presented as a promising nature-based solution for urban resilience, applicable in soil remediation, stormwater management, and carbon sequestration within green infrastructure. However, its widespread adoption faces significant barriers, including inconsistent feedstock supply, high production costs, limited public awareness, and a lack of standardized quality and safety regulations. The study also identifies a critical need for policies that integrate biochar into urban planning frameworks and incentivize its production and application.

Firdavs Berdikulov, Iroda Orifjonova, Bekhzod Eshboev, Jumanazar Xolmurzayev, Bakhtiyor Abdusayitov · Springer Link (Chiba Institute of Technology) · Uzbekistan (Samarkand)

This study examined agricultural growth in Samarkand, Uzbekistan's peri-urban regions from 2000 to 2024, using government data and predictive modeling. It found that urban populations surged while arable land declined, and the vegetable surplus, though currently meeting demand, began shrinking around 2015, suggesting a tipping point toward shortages. The research indicates that without proactive measures like smarter land allocation and advanced irrigation, Samarkand risks a structural food deficit within a decade.

Marvin Joseph F. Montefrio, Nathalie Dagmang · The Journal of Peasant Studies · Philippines (Metro Manila)

This article examines two cases of radical urban agriculture in Metro Manila, Philippines, where urban poor communities strive for food sovereignty and assert rights over contested urban lands. It highlights that the spatiality of material constraints in cities acts as a mediating factor, influencing the formation of rural-urban alliances and the sustainability of urban resistance efforts. The study reveals challenges in establishing and maintaining these alliances due to urban material limitations.

· The MIT Press eBooks · Brazil (Rio de Janeiro), China (Beijing)

This account describes the challenges in building support for Rio de Janeiro's Hortas Cariocas urban farming initiative in 2016. Negotiations among environmental protection officers, education officials, and school administrators generated "fiery discussions" regarding garden placement, teacher training, and incentives. The presence of a foreign professor was used to strengthen arguments for urban farming's benefits.

Urban farming is the third-highest contributor to the city's gross domestic regional product, accounting for 10.66% of total economic output, yet the sector's overall growth fluctuates, and its direct economic impact is underreported. In terms of environmental performance, Kendari's energy consumption and CO₂ emissions exceeded Asian Green City Index thresholds, categorizing the city as "below average" in sustainability.

Popov, Velian · reposiTUm (TU Wien) · Bulgaria (Plovdiv)

This study examines the disappearing phenomenon of informal urban gardening, known as Rancho, in Plovdiv, Bulgaria, focusing on its socio-historical factors. Despite its authentic, decades-long existence, Rancho is neglected and considered outdated, with a lack of legal regulation and its informal character endangering its future. The study proposes a gradual transformation of these areas into community urban gardens with new infrastructures to raise awareness and encourage authorities to reintegrate Rancho into the urban context.

Elias Nuwagaba, Murindwa Rutanga · East African Scholars Journal of Education Humanities and Literature · Uganda (Mbarara City)

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.

Meredith L. Mull, Mario Torralba · Frontiers in Nutrition · Global

This exploratory Q-methodology study investigated how university students in sustainability programs conceptualize sustainable food systems. Analysis revealed five distinct narratives, with consensus on food security and transparent governance. However, elements like urban agriculture, GMOs, and food traditions were consistently deprioritized by the participants. The findings emphasize incorporating plural perspectives and context-sensitive approaches in food system research and policy.

Moschella Miloslavich, Paola · Portal de Revistas PUCP (N/A) · Peru (Cajamarca)

This study in Cajamarca, Peru, analyzed the expansion of the city onto vital agricultural land, examining perceptions, consequences, and solutions through surveys and interviews. It found that weak regulations and external factors accelerate informal subdivision of rural properties, leading to future urban areas lacking public spaces and services. Despite high regard for agricultural land, comfort and the land market override beliefs in decision-making, and initiatives to protect the valley were unsuccessful due to permissive regulations and a lack of political will.

This chapter examines the global growth and implications of urban agriculture. While urban agriculture enhances food security, it also introduces food safety risks from contaminated soils and infrastructure gaps. Challenges related to heavy metals, waste, and inadequate land planning are evaluated, and barriers such as land access and limited training for producers persist.

Jairo Guzman-Molina, Gustavo Carrazana-Rosales, Daniel Karthe, W. C. Tabares Rodríguez, Serena Caucci · Environmental and Sustainability Indicators · Colombia (Bogotá)

To assess the sustainability of Urban and Peri-Urban Agriculture (UPA) in Bogotá, Colombia, a Composite Indicator (CI) integrating 43 variables from an in-depth survey of over 3,500 households was developed. 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.

Mercedes Muriel Sáiz · Dialnet (Universidad de la Rioja) · Spain (Madrid)

This article examines the phenomenon of urban gardens from a socio-community perspective, based on a methodology combining a literature review and participant observation in the community garden Ensancha el huerto (Alcorcón, Madrid). The analysis shows that urban gardens operate as micro-ecosystems of mutual support and learning, but the study also highlights risks associated with institutionalization, commodification, and legal insecurity surrounding such initiatives.

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.
