This study investigated the implications of urban growth on maize yield in Harare metropolitan city, Zimbabwe, from 1984 to 2018 using Landsat data. Cropland area was reduced from 11,120 ha in 1984 to 2631 ha in 2018. Consequently, the estimated average maize yield decreased significantly from 52,264 tons in 1984 to 12,366 tons in 2018, demonstrating that urban growth has the potential to compromise food security.

A systematic literature review on urban farming in Indonesia identified its trend in achieving urban resilience as a response to urban food security issues and an economic boost during the COVID-19 crisis. While urban farming is suggested to promote urban resilience in Indonesia, it has several weaknesses in the urban resilience design due to problems with production, food security, and land scarcity in urban areas.

A study in Bandung, Indonesia, surveyed 321 households to assess urban agriculture's contribution to household food fulfillment and income. The findings showed an insignificant 9% contribution to food fulfillment and a 41.5% contribution to income. This limited impact was attributed to metropolitan complexities, including restricted land access and increasing commercialization.

A prospective cohort study in South Sudan (2019–2021) examined the impact of cash assistance for work in community gardens on food security among 1213 cash-receiving, 582 non-intervention, and 300 later cash-receiving households. The study found no significant differences in changes over time in household hunger, coping strategies, or meal frequency between participants and the comparison group. Cash transfers did not appear to have lasting benefits on food security and livelihoods coping strategy use.

This mixed-methods study surveyed 120 community garden participants in Ward 18, Umdoni Municipality, South Africa, to assess the impact of community gardens on household food security. The survey found that 58.3% of participants did not receive sufficient food from the gardens, and only 15.8% achieved food security, with 40% experiencing moderate food insecurity. Despite their establishment, community gardens appeared ineffective in substantially improving household food security, with challenges including climate change impacts.

Lena Katharina Mietz, Bárbara Civit, Alejandro Pablo Arena · Environmental & Socio-economic Studies · Argentina (Mendoza)

This study investigated vegetable consumption patterns, interest in vegetable production, opinions on urban agriculture, and barriers in the metropolitan city of Mendoza, Argentina. Using quantitative research methods and a citizen survey, the results showed strong interest from citizens in urban agriculture, but also identified barriers such as lack of time and resources.

Jin-Seul Park, Suk-Kyung Kim · 한국실내디자인학회 논문집 · South Korea (Seoul)

This study aimed to derive space planning elements for creating user-centered community spaces utilizing idle spaces in Seoul subway stations. Observation analysis with site visits, using the WELL Community certification standard, was conducted on eight continuously operating community spaces in subway stations in 2022. Findings indicated that "Pedestrian-Scale design of Movement," "Preservation of Scenic views of Mind," and "Social space and Community confidence of Community" were generally satisfied. However, "Urban Agriculture of Nourishment," "Public space of Community," and "Restorative Blue space of Mind" were not sufficiently satisfied.

Marek Hekrle, Jan Macháč, Lenka Dubová · Resources · Czechia

This study investigated how ecosystem services (ES) provided by the community garden 'Žížala na Terase' in Czechia are affected during crises related to the COVID-19 pandemic and increased food prices. Results indicated that the importance of social interaction and educational ES significantly decreased in the COVID-19 scenario. Conversely, the role of community gardens as places for recreation increased. In the food self-provisioning scenario, provisioning ES increased at the expense of recreational ES. Economic assessment further showed that cultural ES were the most monetarily valued, followed by provisioning ES.

Candan Türkkan · Moment Journal · Turkey (Istanbul)

This paper analyzes urban gardening practices in Yedikule Bostanlari and Kuzguncuk Bostani in Istanbul, examining the convoluted relationship between the food movement and urban agriculture. It argues that while urban agriculture initiatives are significant for generating community and proposing alternative uses for urban space, they do relatively little to mitigate the structural problems underlined by the food movement. As such, even though they are examples of urban agriculture in practice, their aspirations do not readily associate with those of the food movement.

This paper proposes agroecological assessment as a tool for formulating evidence-based local food policies, adapting the Tool for Agroecology Performance Evaluation (TAPE) model on a sample of 20 farms in the city-region food system of Rome, Italy. Data analysis showed that agroecological principles are not fully adopted by the majority of farms considered in Rome. Additionally, farms with the highest agroecological level are mainly driven by social factors and have a lower propensity for innovation, which could hinder the transformation process of food systems.

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.

A case study in a low-income former township area in South Africa, involving 140 home garden owners, found that gardens did not substantially contribute to household food security. Only 10% of households were completely food secure, and dietary diversity was very low. Key constraints included cultural practices, a focus on ornamental plants, and reliance on purchased food.

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.

An urban farming program was initiated in Gunung Putri District, Bogor Regency, and qualitative descriptive methods, Likert scale, and SWOT analysis were used to identify development strategies, analyze public perceptions, and formulate strategies. While urban farming showed potential across technical, social, institutional, commercial, financial, and environmental aspects, obstacles included respondents' time, usable land, capital, supportive institutions, and limited marketing information. The most significant weakness identified was product marketing.

The potential and constraints of urban farming development on the railroad border in Bangetayu Wetan Village, Genuk District, Semarang City, Indonesia, were investigated through observation, interviews, and documentation. The approximately 1 to 2-hectare area cultivated crops such as corn, cassava, and sugarcane, with yield predictions sufficient to meet food needs. However, the presence of pests, diseases, and weeds were identified as constraints, indicating challenges for urban farming development.

Participatory Guarantee Systems (PGS) are locally-rooted agroecological governance mechanisms that have garnered interest globally. However, there is little evidence of their development in the United States, where community supported agriculture (CSA) and farmer's markets grew instead, though many of these mechanisms failed to sustain interest and support. This study explores factors driving PGS creation in other global regions and identifies factors shaping a different trajectory for local agriculture in the United States.

This narrative review searched Scopus, the Directory of Open Access Journals, Web of Science, Google Scholar and Academic Search (EBSCO) using terms including "urban farming," "urban agriculture" and "climate change" to synthesize literature on climate change's effects on urban agriculture in sub-Saharan African cities. While reviewed studies agree that climate change affects urban agriculture from production through processing, storage and distribution, integrated literature on the topic remains scarce, and the extent and magnitude of impacts differ by region, meaning adaptation and mitigation strategies cannot be applied universally and must instead be context-specific.

Smart urban agriculture — food produced in closed, controlled and digitally augmented environments such as vertical farms, plant factories and aquaponics systems — is found in cities worldwide and is said to produce fresh food year-round using fewer chemicals and fewer food miles. However, critiques of smart urban agriculture note it is a marginal activity that often produces food with low nutritional value and requires energy-intensive artificial lighting. Using qualitative research methods, this report examines the development of smart urban agriculture in Sweden, identifying experimental and entrepreneurial initiatives and analyzing them in relation to high-level policy agendas such as food policy, smart cities and digitalisation. The findings show Swedish smart urban agriculture broadly consists of technology-oriented entrepreneurial start-ups and experimental initiatives split into production-oriented (mainly herbs and leafy greens), community-oriented (prioritizing social benefits), and technology-oriented (developing and supplying digital solutions and services) types. However, product output was limited to a small variety of financially high-margin crops sold at premium prices. In relation to high-level strategic agendas, smart (urban) agriculture is recognized for environmental and social benefits such as mitigating flooding.

This paper focuses on the social urban garden in the Ponticelli neighborhood on the eastern outskirts of Naples, Italy, an area facing significant social and cultural problems including high unemployment and crime rates. The urban garden demonstrates how social cohesion can be built through urban agriculture and contribute to sustainability. However, the initiative risks remaining isolated and providing limited benefit to regional environmental sustainability efforts if not framed within an overall metropolitan strategy.

This review examines the potential of urban agriculture by the elderly to support food security. While urban agriculture could produce 180 million tons of food globally per year, representing 10% of total global food production, it is currently insufficient to meet urban food needs, with urban food supply still heavily reliant on rural areas and imports. With an increasing urban elderly population, empowering seniors through urban agriculture technologies like vertical farming is proposed as an opportunity for food security.

This article analyzed precipitation data in Pointe-Noire, Republic of Congo, using agronomic criteria and frequencies to understand rainy season behavior for agricultural planning. The study found that Pointe-Noire has a bimodal rainfall regime, allowing for two cultivation periods annually. However, the rainy seasons are very random, with increasingly late starts, early endings, and shortening durations over the years.

This paper discusses rooftop gardens as an alternative for vegetable production in Bhubaneswar City, India. While rooftop agriculture can improve ecosystem services and enhance urban biodiversity, vegetable production activities on rooftops are limited due to multiple challenges that need to be addressed for widespread implementation. Rooftops are not a total solution for food security but can supplement other urban food sources.

Salvatore Engel‐Di Mauro, George Martin · · Global

Claims that urban food production raises food security and creates a more just society are questionable and contradicted by data from the Global North. Urban land is insufficient, sunlight is often inadequate, and soil pollution is widespread. Technological attempts like vertical and rooftop farming have limited feasibility, may worsen environmental and social problems, and do not address major food sources, access, or waste. Furthermore, urban gardens are increasingly linked with socially devastating gentrification.

This study explored the potential and limitations for agroecological scaling through formal educational structures, using the LabVida school gardens program in Chiapas, Mexico as a case study. Through training, educators gained an appreciation of agroecology and applied practices in their school gardens, although their understanding of agroecological principles and scientific process remained limited. The program's greatest impact was on educators’ eating habits and their perception of the value of local knowledge and its relevance to schoolwork.
