A study analyzed urban agriculture supply chains in Havana, Kigali, Bissau, and Singapore based on fieldwork conducted from 2018 to 2020. It found that while shortened supply chains are typical for urban agriculture, their benefits are not arbitrary and depend on local economic, social, and spatial conditions, as well as the supply chain's organization and structure. The positive effects of localized food production are not universal, indicating a need for further research into supply and value chain structures.

Jelena Živanović Miljković, Vesna Popović, Aleksandra Gajić · Land · Serbia (Novi Sad)

A study conducted in Futog, Novi Sad, Serbia, investigated land take (LT) processes and challenges for urban agriculture, focusing on the role and implications of land use planning. Quantifying LT for 2000–2018 using CORINE Land Cover and Urban Atlas datasets revealed that a significant portion of agricultural land in Futog, registered as a Geographical Indication (GI) for Futog cabbage, was planned for conversion into construction land. The study concluded that current land use planning in Serbia is inadequate to ensure the protection of either urban agriculture or GIs.

Diana Galos, Silviu Medeşan · sITA · Romania (Cluj-Napoca)

This study examines the case of urban gardening in the "La Terenuri" area of Mănăștur neighborhood, Cluj-Napoca, Romania. Residents began gardening in the land between buildings during the 1970s and 1980s, influenced by communist laws encouraging food production and green space care. This phenomenon utilized the skills of rural residents to complete "socialist utopian projects" when resources were insufficient, leading to the creation of strong, lasting community groups.

Elias Danyi Kuusaana, Isaac Ayurienga, Joyce A. Eledi Kuusaana, Joseph Kwaku Kidido, Ibrahim Abu Abdulai · Frontiers in Sustainable Food Systems · Ghana (Bolgatanga)

A study in Bolgatanga Township, Ghana, used field surveys, key informant interviews, and GIS mapping to examine urban agricultural practices. It found that agricultural lands significantly decreased in size and contiguity since 1996 due to urban sprawl, forcing farmers to use segregated plots and undeveloped residential areas which are easily lost to development. The study concluded that urbanization exacerbates food production challenges without policies to protect agricultural lands.

Ndeyapo Nickanor, Lawrence N. Kazembe, Jonathan Crush · · Namibia

A household survey of 853 households in Namibia's Oshakati-Ongwediva-Ondangwa (OOO) urban corridor found 77% household food insecurity and a mean dietary diversity of less than 5. The most common coping strategies were relying on less preferred and less expensive foods (67%) and rural-urban food transfers (55%). Urban agriculture was found to be very limited in this region.

Stella Kabiri, Molly Allen, Judith Tomma Okuonzia, Beatrice Akello, Rebecca Ssabaganzi, Drake N. Mubiru · Open Research Africa · Uganda

This study investigated the extent of wetland loss and encroachment by urban agriculture in Wakiso and Kampala, Uganda, over 30 years from 1986 to 2016. Using field surveys, Landsat, and MODIS NDVI data, the analysis found that 72,828 ha (73%) of Wakiso-Kampala wetlands were lost, while agricultural areas doubled. Of this, 16,488 ha (23%) were converted from wetlands, with all cultivated agriculture in Kampala occurring in wetlands and 73% in Wakiso.

A. Smaliychuk, Dmytro Khiblin · Vìsnik Nacìonalʹnogo unìversitetu Lʹvìvsʹka polìtehnìka Serìâ Arhìtektura · Global

This study discussed the necessity of active development of food production at the local level to prevent a predicted global ecological collapse and inability to feed the human population after 2050. It proposed that locating agricultural production in anthropogenic environments and making the synergy of energy, agricultural production, and waste recycling a key structural planning principle for architectural objects would ensure food security and impact urban planning structures. Local food production capacity would limit the maximum size of megacities and contribute to a more dispersed settlement structure.

This study used a Life Cycle Analysis (LCA) to compare the environmental impacts of eight scenarios for fresh tomato supply to urban citizens. Zero-miles production in heated greenhouses showed the highest environmental impact (GWP 0.33 kg CO2 eq/kg tomato), performing worse than unheated greenhouses with long-distance transport (GWP 0.21 kg CO2 eq). Conversely, open-field zero-miles production was the most environmentally favorable option (GWP 0.12 kg CO2 eq), and product travel distance was less important than transport efficiency. Urban Agriculture was not environmentally superior to zero-miles agriculture carried out in rural areas.

Emma Burnett · Smart Cities · Global

This chapter explores the complex relationship between urban environments, food, and agriculture, examining divergent philosophies on agriculture's future. It discusses the role of technology in both rural and urban agriculture, how food production integrates into cities, and various urban agriculture practices. The text investigates the benefits and drawbacks of technology in food systems and the impacts of Smart City technologies, suggesting that clever city development should align with practitioners' needs to build resilient urban food systems.

Francesca Peroni, John Michael Humphries Choptiany, Samuel Ledermann · · Global

This chapter explores the role of agroecology in smart cities and investigates how Information and Communications Technologies (ICT) could spread agroecological approaches to boost urban agriculture. Smart cities are criticized for their inability to build just and inclusive environments, and ICT alone cannot guarantee sustainable development. While agroecology enhances ecosystem services and human well-being, its introduction in urban ecosystems is complex. The chapter suggests ICT could provide tools to enhance dwellers' competencies in practicing agroecology, ultimately exploring how smart urban agriculture contributes to food sovereignty and ecosystem service maintenance.

Ana Zazo Moratalla, Alejandro Orellana-McBride, Claudia Cerda-Inostroza · · Chile

A study investigated how Chilean urban planning has conceived productive agriculture within urban limits, analyzing the evolution of territorial planning instruments in five Chilean cases. While agriculture was once conceived as an urban use, changes in Chilean legislation have led to this activity being conceived as transitory and in fallow, inevitably transforming into other more profitable urban uses.

This study investigated urban growth and urbanization in N'Gaous, Algeria, over the last 60 years, using an analytical approach and Geographic Information Systems to assess the agronomic potential of soils. It found that N'Gaous experienced significant urban sprawl, with its land area expanding over ten times and population increasing more than six times, leading to serious issues for peri-urban orchards. The study quantified and monitored the agricultural potential consumed by construction, highlighting the negative impact of urban expansion on agricultural land.

Gizaw Ebissa, Hayal Desta · City and Environment Interactions · Global

This study extensively reviewed the literature on how urban agriculture (UA) can contribute to flooding risk management for building water-resilient cities. UA plays a key role in transforming linear water economies into circular ones, thereby reducing urban areas' dependence on rural areas for ecosystem services, including flood risk management. UA exhibits higher infiltration capacity, and urban flood-prone areas can be allocated to UA for flood management. The Sponge City Concept demonstrated the possibility of reducing 100-year storms to 25-year storms.

The contemporary industrial food system is problematic, producing diverse foods for a small elite and replicating past labor injustices rooted in colonialism. Urban agriculture is a growing global trend and is expected to be the future of food production. The future of food will also diversify what we eat, including aquaponic tilapia, sprouts, algae, fungus and yeast-derived foods, and imitation meats.

Tong Zou, Ali Cheshmehzangi, Ayotunde Dawodu, Eugenio Mangi · Journal of Resilient Economies (ISSN 2653-1917) · Global

This study investigated how urban agriculture can improve the sustainability and resilience of the urban food system through the analysis of existing literature. The literature review, conducted on April 11, 2022, on the Web of Science database, included bibliographic coupling, co-citation analysis, and co-occurrence analysis. Findings highlighted that urban agriculture alone cannot substitute large-scale food systems in the short term, but it could be a promising approach in the future.

Abdulaziz I. Almulhim, Patrick Brandful Cobbinah · International Journal of Sustainable Development & World Ecology · Saudi Arabia

This article reviews literature on urbanization and its implications for the urban environment in Global South cities, discussing eight implications of the urbanization-environmental conundrum with cases from Saudi Arabian cities. Findings indicate that the sustainable development agenda in Saudi Arabian cities is skewed towards socio-economic development with limited focus on environmental issues. This situation is threatening the sustainability of rapidly urbanizing cities.

Giulia Caterina Verga, Ahmed Z. Khan · Frontiers in Built Environment · Belgium (Brussels)

This study examined spatial factors fostering or hampering the embedding of urban circularity practices (UCPs) in the Brussels Capital Region (BCR) through a literature review and case-study research. It showed that access to spaces and land emerges as one of the most recurrent barriers to embedding UCPs. Beyond real estate prices, frictions in political agendas where the need for housing, productive spaces, urban agriculture land, and green-blue infrastructures compete for the same limited space also contribute to this issue.

Pierre Michard Beaujour, Frank Cézilly · Caribbean Journal of Science · Haiti (Port-au-Prince)

This survey assessed the distribution of pollinating insect orders in 16 urban green sites in Port-au-Prince, Haiti, from January to April 2018. Researchers collected 2,747 pollinating insects and found that insect order richness was significantly higher at agroforestry plantations compared to unexploited forest remnants. Site area, elevation, and built area percentage had no significant influence on the total number of insects collected.
